Technical Field of the Invention
[0001] The present invention relates to a method for starting an engine and stopping the
engine after the engine has started. The invention also relates to a computer program
and a control unit for starting and stopping the engine.
Background of the invention
[0002] Remote engine starting systems are well known and incorporated in many road vehicles
today. By e.g. pushing a button on a handheld radio signal transmitter, a person is
able to remotely start an engine of a vehicle. US-5673017-A is one example of a number
of documents that disclose such a starting system.
[0003] However, soon after the engine has been remotely started, the person who initiated
the starting might discover various signs of a critical problem, which directly or
indirectly is associated with the running engine. Such signs may be e.g. leakage from
a hose for hydraulic oil and a jarring sound from e.g. the engine or a power take
off. None of the remote engine starting systems provides any means for stopping the
engine. A person has to get into the cab of the vehicle and turn off the engine with
a key or the like. Damage caused on the vehicle or the environment (e.g. due to oil
leakage) due to the time it takes to get into the cab and turn off the engine, can
sometimes be substantial and cost a considerable amount of time and money to repair.
Valuable time and money for using the vehicle are also lost, for example if the vehicle
is a hauling vehicle owned by a hauling contractor.
[0004] Some vehicles have a stop button/switch for the engine on the outside of the vehicle,
but substantially the same problem with the time it takes to stop the engine remains
for these vehicles. The person has to locate the stop button and touch the stop button
before the engine is stopped.
Summary of the invention
[0005] An object of the present invention is to provide a faster and easier way of avoiding
damages directly or indirectly caused by a running engine after a sign of a problem
that causes the damages has been detected by a person.
[0006] The invention relates to a method for starting an engine, e.g. in a vehicle, and
stopping the engine after the engine has started. The method comprises the steps of:
starting the engine by affecting, e.g. depressing or touching, an activation means
of a remote control unit;
staying in physical contact with the activation means during the starting of the engine
and a time after the engine has started; and
stopping the engine by releasing the physical contact with the activation means before
a predetermined time has passed after the engine has started.
Hereby is achieved that the engine is stopped, merely by releasing the physical contact
with the activation means, after the engine has started to run. Thus considerable
time is saved, since an operator of the remote control unit does not have to locate
and get to a position, such as the cab of the vehicle, where the engine can be deactivated.
Throughout the description and claims, the starting of the engine is defined as an
attempt to start the engine, which at the initiation moment of the attempt is at rest.
The definition of when the engine has started is throughout the description and claims
when any predetermined condition known in the art for defining that the engine is
capable of running on its own is fulfilled, such as the condition that the engine
is defined as started when the engine speed has reached a certain predetermined level.
[0007] The method may also comprise the step of stopping the starting of the engine if the
engine has not been started before a time limit after the starting of the engine has
begun. Hereby is achieved that an attempt to start the engine with an electric starter
motor is stopped if the time limit is reached. Hence an undesired discharge of a vehicle
battery connected to a starter motor is avoided. The time limit may be within a time
interval of 2-20 seconds.
[0008] The method may comprise the step of allowing the starting of the engine only if all
of at least one start criterion is fulfilled, one of the at least one start criterion
is that a remote control switch means allows the starting of the engine through the
remote control unit. Hereby is achieved that an undesired starting of the engine from
the remote control unit is avoided if it is not permitted through a position of a
remote control switch means. Hence safety is enhanced.
[0009] In one aspect of the method, the method comprises the step of sending a start confirmation
signal from the remote control unit to a control unit for the engine when the physical
contact with the activation means is released. Hereby is achieved that a continuous
signal for indicating that the activation means still is affected can be avoided,
thus saving power requirements for the remote control unit.
[0010] In another aspect of the method, the method comprises the step of substantially continuously
send a signal from the remote control unit as long as the activation means is affected.
Hereby is achieved that the control unit may sense that the operator of the remote
control unit has released the physical contact with the activation means when the
signal from the remote control unit ends.
[0011] The predetermined time may be between 0.1-6.0 seconds, for example 1 second.
[0012] The method may also comprise the step of activating at least one light emitting means
immediately after the predetermined time has passed if there still is physical contact
with the activation means at the predetermined time. Hereby is achieved that the operator
is able to see that the engine has been started successfully and that the physical
contact with the activation means can be released without stopping the engine. The
visual indication from the light emitting means makes it easier for the operator to
feel safe when starting the engine in a noisy environment and/or at a longer distance
from the vehicle.
[0013] The invention also relates to a computer program for starting an engine and stopping
the engine after the engine has started, comprising computer readable program code
means for adapting a control unit to receive a signal generated by affecting an activation
means of a remote control unit, the signal indicating a desire to start the engine;
computer readable program code means for causing the control unit to initiate starting
of the engine after the signal has been received;
computer readable program code means for causing the control unit to determine when
the engine is started or receive information that the engine is started; and
computer readable program code means for causing the control unit to initiate stopping
of the engine, if the activation means has been released before a predetermined time
has passed after the engine has started. The initiation shall throughout the description
and claims be defined as direct or indirect through another control device ordering
a start of the engine.
[0014] The computer program may comprise computer readable program code means for stopping
the starting of the engine if the engine has not been started before a time limit
after the starting of the engine has begun.
[0015] The computer program may comprise computer readable program code means for causing
the control unit to check if all of at least one start criterion is fulfilled for
the starting of the engine, and
computer readable program code means for causing the control unit to only allow the
starting of the engine if all of the at least one start criterion is fulfilled, one
of the at least one start criterion being that a remote control switch means is in
a position where the starting of the engine through the remote control unit is allowed.
[0016] In one aspect of the computer program, it comprises computer readable program code
means for adapting the control unit to receive a start confirmation signal from the
remote control unit for confirming that the engine, if running, should continue to
run.
[0017] The computer program may also comprise computer readable program code means for causing
the control unit (8) to transmit an indication signal immediately after the predetermined
time has passed if there still is physical contact with the activation means, the
indication signal initiating an activation of at least one light emitting means immediately
after the predetermined time has passed.
[0018] Furthermore, the invention relates to a computer program product comprising a computer
usable medium and the computer program, wherein the computer program is comprised
in the computer usable medium.
[0019] Moreover, the invention relates to a control unit adapted to initiate starting of
an engine and stopping the engine after the engine has started, comprising a processing
means, a storing means, the computer program comprised in the storing means and means
for direct or indirect communication with a starter motor for the engine, the engine
and a remote control unit.

Detailed Description of Embodiments
[0021] While the invention covers various modifications and alternative constructions, some
embodiments of the invention are shown in the drawings and will hereinafter be described
in detail. It is to be understood that the specific description and drawings are not
intended to limit the invention to the specific forms disclosed. On the contrary,
it is intended that the claimed invention includes all modifications and alternative
constructions thereof falling within the scope of the invention as expressed in the
appended claims.
[0022] Fig. 1 schematically shows a vehicle 1 in the form of a truck and a remote control
unit 2 associated with the vehicle 1. The remote control unit 2 comprises an activation
means 3 in the form of a spring loaded push button. When depressing the push button,
a signal is generated and inputted into a transmitter circuit 4 for generating a signal,
here in the form of a radio signal, radiated from an antenna 5 in the remote control
unit 2. In an embodiment adapted for a first aspect of a method described below, the
signal is transmitted as long as the activation means 3 is depressed, against the
force of a spring element (not shown). The signal ends as soon as the push button
is returned to its position of rest. The signal may be a continuous or pulsated radio
wave. Although radio signals are used in this embodiment, signals emitted from the
remote control unit 2 may of course be transmitted to the vehicle 1 in the form of
another kind of wirelessly transmitted signals, such as infra-red signals, or as electrical
signals through a wire connected to the vehicle 1. In a second embodiment adapted
for a second aspect of the method described below, the signal is shorter and substantially
only sent at the moment when the push button first is depressed. When the push button
is released, the remote control unit 2 according to the second embodiment transmits
a start confirmation signal. In a third embodiment adapted for a third aspect of the
method described below, the remote control unit comprises a first timing circuit 6.
Through the first timing circuit 6, the remote control unit 2 is able to first send
a signal in the moment when the push button is depressed and also a confirmation signal
after a certain predetermined time provided that the push button still is depressed
at the predetermined time. In a fourth embodiment, where the remote control unit 2
is connected to the vehicle through a signal wire, the remote control unit 2 lacks
the antenna 5 since the antenna 5 is not needed.
[0023] The embodiment shown in the Fig. 1 also comprises a light emitting means 30, e.g.
in the form of a diod or a bulb. The light emitting means 30 is adapted to emit visible
light after the predetermined time provided that the push button still is depressed
at the predetermined time.
[0024] Fig. 2 shows a system installed in the vehicle 1 for achieving the effects of the
invention. The shown system is applicable to the first, second and third embodiment
described above. A receiver unit 7 comprising an antenna and a decoder is connected
to a control unit 8, which also is connected to an electronic engine control unit
9 and a light control unit 32 via a CAN (Control Area Network) Bus 10. The engine
control unit 9 controls an internal combustion engine 11 and an associated electric
starter motor 12. The starting of an engine with the help of a starter motor and an
electronic engine control unit is as such known in the art and will therefore not
be described in more detail. Any conventional engine starting method for combustion
engines in vehicles may be used in combination with the invention. The light control
unit 32 controls at least some vehicle exterior light emitting means, such as flashers,
warning lights and the main lights of the vehicle 1. The vehicle exterior light emitting
means are here only illustrated with reference sign 34. The control unit 8 is also
connected to an engine revolution sensor 13 (engine speed counter), a neutral gear
sensor 14, a parking brake sensor 15, a stop switch means 16 preferably on the outside
of the vehicle 1 and a remote control switch means 17 in the cab (not shown) of the
vehicle 1. The stop switch means 16 may be e.g. a button or lever switch with two
positions; a first position that stops a running engine or prevents the engine 11
to be started and a second position for allowing the engine 11 to start and run. The
remote control switch means 17 may also be a button, a toggle switch or a lever switch
with two positions, where a first position allows the engine 11 to be started and
stopped through the remote control unit 2 and a second position which prevents attempts
to start and stop the engine 11 through the remote control unit 2.
[0025] In the fourth embodiment, where the remote control unit 2 is connected to the vehicle
1 through a signal wire (not shown), the receiver unit 7 is not needed. Instead the
remote control unit 2 may be connected directly to the control unit 8.
[0026] Fig. 3 schematically illustrates the control unit 8, which comprises a processing
means 18 in the form of a CPU (Central Processing Unit) connected to a first port
191 via a first bus 201 for communication with the engine control unit 9 and the light
control unit 32, a second port 192 via a second bus 202 for communication with the
receiver unit 7, and a third port 193 via a third bus 203 for receiving signals from
the sensors 13-15 and switch means 16-17. The CPU is also connected to a storing means
21, such as a hard disk, a flash memory, a ROM (Read-only memory) or any other computer
readable computer program product, via a fourth bus 204. A computer program comprises
a criteria checking program module 22, an engine speed monitoring program module 23,
a time checking module 24, a module 25 for detecting incoming decoded signals from
the receiver unit 7 and communication interface program modules 26 for causing the
control unit 8 to communicate with the engine control unit 9 and the light control
unit 32 and receiving information from the receiver unit 7, the sensors 13-15, the
stop switch means 16 and the remote control switch means 17. For the purpose of the
second and third aspect of the method (see below) according to the invention, the
computer program comprises a module 27 for detecting incoming decoded start confirmation
signals from the receiver unit. The modules, i.e. parts, of the computer program,
may in an alternative embodiment be separate computer programs interacting with each
other and stored in different storing means in or outside the control unit 8 and/or
the engine control unit 9. In the fourth embodiment the second port 192 and the second
bus 202 are used for receiving signals directly from the remote control unit 2 through
a signal wire.
[0027] Having described a system according to the invention, a first aspect of the method
according to the invention will now be described in conjunction with Fig. 4.
[0028] The push button is pushed in order to start the engine 11 through the remote control
unit 2. A signal is thereby sent from the remote control unit 2. This is done in a
first step S1.
[0029] In a second step S2, the signal is received by the receiver unit 7, which decodes
the signal and sends the decoded signal to the control unit 8. The module for detecting
the incoming decoded signal comprises a program loop for frequent and regular determination
of whether a decoded signal is sent from the receiver unit 7. This means that the
control unit 8 detects when a received decoded signal ends.
[0030] Next, in a third step S3, the control unit 8 receives the decoded signal and checks
whether or not predetermined start criteria for starting the engine 11 are fulfilled.
Start criteria for starting the engine 11 through the remote control unit 2 may be
that the engine speed is zero, a gearbox (not shown) in the vehicle 1 is in its neutral
position, a parking brake (not shown) of the vehicle 1 is applied, the stop switch
means 16 allows the engine 11 to be started and/or that the remote control switch
means 17 allows starting of the engine 11 through the remote control unit 2. The control
unit 8 receives information from the engine revolution sensor 13 about the engine
speed, i.e. a value of the instantaneous revolutions per minute performed by the engine
11. The neutral gear sensor 14 produces a signal to the control unit 8 according to
the position of a gear lever (not shown) of the vehicle 1, the signal being indicative
of whether or not the gear lever is in the neutral position. Similarly, the parking
brake sensor 15 may produce a signal indicative of whether or not the parking brake
is applied. As long as at least one of the criteria is not fulfilled, the decoded
signal is ignored and the method continues to step S4, where warning signals are emitted
from e.g. warning lights on the vehicle, a horn and/or loudspeakers in the vehicle
1. A person who tries to start the engine 11 through the remote control unit 2 is
thereby easily informed that the engine 11 is not allowed to be started. The person
would then probably release the push button on the remote control unit 2 and investigate
the cause of why the engine 11 is not allowed to be started. After step S4, the method
returns to step S2, where it is checked if the signal from the remote control unit
2 still is received or if the signal has ended. As long as the decoded signal is received
and any one of the start criteria is not fulfilled, the steps S2, S3 and S4 will be
repeated as a loop. If it is determined in step S2 that the decoded signal has ended,
the method ends.
[0031] If all start criteria are fulfilled, the answer is 'yes' and the method continues
with a fifth step S5, in which the control unit 8 initiates the start of the engine
11 by sending a start request signal to the engine control unit 9, which attempts
to start the engine 11 with the help of the electrical starter motor 12.
[0032] As long as the decoded signal is sent to the control unit 8, the electric starter
motor 12 will try to start the engine 11. This is done in a sixth step S6. The time
when the engine 11 starts is defined as the moment when the engine 11 speed has reached
a predetermined speed (e.g. revolutions/minute). The instantaneous speed is monitored
through the engine revolution sensor 13 and the engine speed monitoring program module
23 in the control unit 8. If the decoded signal ends before the time when the engine
11 has reached the predetermined speed, the starting procedure is stopped; else the
method continues with a seventh step S7.
[0033] A time limit, for example 20 seconds, is set for trying to start the engine 11. In
step S7, it is determined if the time limit has been reached without achieving a successful
starting of the engine 11. This is done with the help of the time checking program
module 25. If the answer is "Yes", i.e. the attempt to start the engine before the
time limit has failed, the starting attempt is stopped. Hence discharge of a vehicle
battery may be avoided automatically. If the engine 11 starts before the time limit,
i.e. if the answer is "No", the method continues with an eighth step S8.
[0034] In step S8, it is checked if the engine has started. If not, the method returns to
step S7. If the engine has started, i.e. reached the predetermined speed, the method
continues with a ninth step S9 provided that the decoded signal is still received
by the control unit 2.
[0035] In step S9, immediately after the engine has reached the predetermined speed, the
control unit 8, through e.g. a timing circuit in the CPU, starts to count the time.
During step S9, the module 25 for detecting incoming decoded signals from the receiver
unit 7 also causes the control unit 8 to check whether the decoded signal is still
being received during a predetermined time, for example 4 seconds, after the engine
11 has started. If the decoded signal is still received by the control unit 8 when
the timing circuit has counted up to the predetermined time, the engine 11 is allowed
to run although the push button is released after the predetermined time. Also, if
the predetermined time has passed, the control unit 8 sends an indication signal to
the light control unit 32, which upon receiving of the indication signal turn on at
least some of the lights 34, such as the flashers, to show the operator that the engine
has been started successfully and that the push button can be released without affecting
the engine. If the decoded signal ends before the predetermined time, the control
unit 8 sends a stop signal to the engine control unit 9, which upon reception of the
stop signal stops the engine 11.
[0036] In a first step S 11 of a second aspect of the method according to the invention,
see Fig. 5, the remote control unit 2 sends a signal to the receiver unit 7 when the
push button is depressed. However, this signal is not a continuously transmitted or
pulsed signal during a relatively long period as in the first aspect. This signal
ends substantially as soon as e.g. identification data associated with the remote
control unit 2 for authorisation and authentication and data requesting start of the
engine 11 have been sent.
[0037] In a second step S12 of the second aspect, the signal is received by the control
unit 8 through the receiver unit 7. The second aspect continues with a third step
S 13, which corresponds to the third step S3 of the first aspect. If the start is
not OK, i.e. at least one of the start criteria is not fulfilled, the method continues
with a fourth step S14, which corresponds to the fourth step S4 of the first aspect.
After step S 14, the method ends. On the other hand, if all start criteria are fulfilled,
a fifth step S 15 follows, in which the control unit 8 sends a start request signal
to the engine control unit 9, which attempts to start the engine 11 with the help
of the electric starter motor 12. Also, the timing circuit in the CPU starts to count
the time.
[0038] As soon as the push button is released, the remote control unit 2 sends a start confirmation
signal to the receiver unit 7, which decodes the start confirmation signal and forwards
it to the control unit 8, where the module 27 for detecting incoming decoded start
confirmation signals causes the control unit 8 to detect the incoming confirmation
signal from the remote control unit 7. The time from the initiation of the starting
in step S 15 to the reception of the start confirmation signal is registered with
the help of the timing circuit in the CPU and time checking program module 24.
[0039] In a subsequent sixth step S16 after step S 15, the control unit 8 checks for a received
decoded start confirmation signal. The method continues with a seventh step S17, if
such a signal has not been received. If the start confirmation signal has been received,
the method continues with an eighth step S 18.
[0040] In step S 17, the time that has passed since the initiation of the starting, is compared
with a time limit, which corresponds to the time limit of the first aspect. If the
time limit has been reached, the control unit 8 sends a stop signal to the engine
control unit 9 for stopping the starting of the engine 11. If the time limit has not
been reached, the method returns to step S16.
[0041] In step S18, it is checked whether the engine 11 has started or not. If the engine
has not started, the control unit sends a stop signal to the engine control unit 9
for stopping the starting of the engine 11. If the engine has started, the method
continues with a ninth step S19, in which the time from the initiation of the starting
to the receiving of the start confirmation signal is compared with a predetermined
time. This comparison is conducted with the help of the time checking program module
24. If the predetermined time is longer than the other time, the push button is considered
as being released too early and the control unit 8 sends a stop signal to the engine
control unit 9 for stopping the running engine 11. If the time from the initiation
of the starting to the receiving of the start confirmation signal is longer than the
predetermined time, the starting of the engine 11 is considered as confirmed and the
engine 11 is allowed to continue to run.
[0042] In a third aspect of the method according to the invention, the remote control unit
2 is able to first send a signal for starting the engine 11 and after a certain predetermined
time send a confirmation signal provided that the push button still is depressed at
the predetermined time. This predetermined time corresponds to the predetermined time
for the other two disclosed aspects above. When the start confirmation signal is received,
it is checked if the engine 11 has started. If not, the timing circuit in the CPU
starts to count up to a time limit corresponding to the time limit of the two other
aspects disclosed above. When the time limit has passed and the engine 11 has still
not started, the attempt to start the engine is stopped. If the engine 11 is running
when the start confirmation signal is received by the vehicle 1, the start of the
engine 11 is considered as being confirmed by the operator of the remote control unit
2. If the start confirmation signal is not received by the vehicle 1 within a certain
time interval, e.g. in the case where the operator of the remote control unit 2 has
discovered that something is wrong and released the push button, the remote control
unit 2 sends a stop signal to the engine control unit 9 for stopping the starting
or running of the engine 11, depending on whether the engine 11 has been defined as
started or not.
[0043] The predetermined time may be a user adjustable parameter in order to suit different
work situations, vehicles and personal preferences. Typically the predetermined time
may be set to any value between 0.0-6 seconds, e.g. 1 second.
[0044] In all the three aspects mentioned above, the first timing circuit 6 may count up
the time until the predetermined time, provided that the push button is depressed
the whole time. As the predetermined time is passed, the light emitting means 30 is
turned on to show that the push button can be released.
[0045] The invention is not limited to starting and stopping of combustion engines, but
may be utilised for e.g. electric motors and gas turbine engines for vehicles as well.
The activation means may of course be any kind of means that could be affected by
a person, e.g. a touch sensitive pad, a toggle switch or a lever switch. Also, the
computer program may be installed in the engine control unit 9 and the receiver unit
7 may be connected directly to the engine control unit 9, thus avoiding the need for
a separate control unit 8 for managing the method according to the invention. Furthermore,
other criteria for defining the actual start of the engine 11 may be used instead
of or in addition to the predetermined engine speed. An example of such a criterion
is that a second predetermined time has passed after the initiation of a starting
attempt. The second predetermined time may be dependent on the engine temperature
at the moment of the initiation of the starting attempt.
