Description

[0001] This invention relates to an identification device for a remote control arrangement of a vehicle, in particular for a remote access control arrangement of a vehicle and to a remote control arrangement for a vehicle, in particular remote access control arrangement for a vehicle.

[0002] Modern vehicles are commonly equipped with remote keyless systems (RKS), such as a remote keyless entry system (RKE) for remotely locking and unlocking of the vehicle doors or a remote keyless ignition system (RKI) for remotely starting the vehicle engine.

[0003] Known remote keyless systems comprise a portable key unit having one or more push-buttons allowing the user to send command signals to a receiving device of a vehicle. Upon receipt of the command signal a control unit of the vehicle then initiates the desired action, e.g. the locking or unlocking of the vehicle doors.

[0004] Since nowadays almost everyone carries a mobile phone, vehicle manufacturers as well as original equipment manufacturers commenced developing remote keyless systems that can be coupled with or integrated into such mobile phones.

[0005] In DE 10 2010 030 578 A1 a vehicle remote control arrangement comprising an identification device is disclosed, wherein the identification can be integrated into a mobile phone. The identification device allows for locking the vehicle doors by using the user interface of the mobile phone. However, the identification device has to be integrated into the hardware of the mobile phone and therefore a quick and easy extension of the mobile phone functionality is not possible without great efforts. Hence, the disclosed identification device cannot be used as a toolless retrofittable electronic module for portable communication devices.

[0006] The object of the invention is to provide a solution for a quick and easy extension of the functionality of a control device such that the control device can be used as a remote control device for a vehicle.

[0007] The object is solved by means of an identification device for a remote control arrangement of a vehicle, in particular for a remote access control arrangement of a vehicle according to claim 1. Further developments are subject-matter of the sub-claims.

[0008] The identification device according to the invention comprises a first communication module configured for wirelessly transmitting a remote control signal to the vehicle. The remote control signal can be, for instance, a signal for locking or unlocking of one or more vehicle doors, a signal for closing or opening of one or more vehicle doors, a signal for closing or opening of one or more vehicle windows or a signal for starting the vehicle engine. The identification device according to the invention further comprises a second communication module configured for wireless communication with a control device, such as a mobile phone. The second communication module has an energy supply unit that is configured for generating electrical energy out of the wireless communication with the control device for supplying the first communication module with that generated electrical energy. According to the invention the first communication module and the second communication module operate at different frequencies. Since the identification device is capable of wirelessly transmitting the remote control signal to the vehicle at a first frequency and wirelessly communicating with the control device at a second frequency, different than the first frequency, the communication module of vehicle and the control device can operate at different frequencies. Therefore, a hardware modification is neither required at the vehicle nor at the control device in order to establish a communication between the control device and vehicle using the identification device as a gateway device.

[0009] Hence, the identification device allows for a quick and easy extension of the functionality of the control device such that the control device can be used as a remote control device for the vehicle.

[0010] The energy supply unit of the identification device preferably is configured for generating electrical energy by converting electromagnetic radiation energy of the wireless communication with the control device into electrical energy. For converting the electromagnetic radiation energy and providing it to the electric circuitry of the first communication module the energy supply unit preferably comprises an antenna for converting the electromagnetic radiation energy into electrical energy, a rectifier for converting the resulting alternating current into direct current, a charge pump for raising the voltage level and/or a voltage regulator for maintaining a constant voltage level.

[0011] In a preferred embodiment, the identification device according to the invention further comprises a detector device for detecting the presence of electromagnetic radiation energy.

[0012] In another embodiment of the identification device according to the invention, the energy supply unit is also configured for supplying the second communication module and/or other electrical components of the identification device with the generated electrical energy.

[0013] In an advantageous embodiment of the identification device according to the invention, the first communication module comprises a radio frequency (RF) transmitter. The radio frequency transmitter preferably operates at a frequency of 315 MHz, 433, 93 MHz, 868 MHz or 915 MHz. Since the majority of modern automotive vehicles have at least a receiving unit configured for wirelessly receiving signals at one of these frequencies there is no need to add any electronic communication equipment to the vehicle in order to allow the vehicle to receive signals from the identification device.

[0014] Alternatively or additionally, the first communication module of the identification device comprises a Bluetooth transmitter, an infrared transmitter or a near field communication (NFC) transmitter for wirelessly transmitting the remote control signal to the vehicle. Modern automotive vehicles which are adapted to the needs of public carsharing often use Bluetooth, infrared or NFC communication for the remote access control system. The identification device according to this embodiment is also capable of transmitting a remote control signal to such vehicles.

[0015] In one embodiment of the identification device according to the invention, the second communication module is configured for near field communication. The second communication module preferably operates at a frequency of 13,56 MHz. By means of near field communication a quick and secure signal and data transmission is possible. Furthermore, near field communication allows for a transfer of signals and/or data only within a range of approximately 20 centimeters and therefore manipulating or intercepting the signals or the data packages being transmitting between the control device and the identification device is made very difficult.

[0016] In a preferred embodiment of the identification device according to the invention, the first communication module is configured for transmitting the remote control signal to the vehicle upon receipt of a command signal from the control device at the second communication module. This allows for transmitting a remote control signal from the identification device to the vehicle without having a user interface on the identification device. The transmission of remote control signals to the vehicle can be controlled just through the control device with this embodiment.

[0017] The identification device preferably comprises a microcontroller operatively coupled with the first communication module and the second communication module, wherein the microcontroller is configured for prompting the first communication module to initiate the transmission of the remote control signal to the vehicle upon receipt of the command signal at the first communication module.

[0018] In another embodiment of the identification device according to the invention, the first communication module comprises a receiver for wirelessly receiving a data signal from the vehicle. The data signal may contain, for instance, information regarding the lock status of the vehicle, the gas level of the vehicle in case the vehicle comprises a combustion engine, the state of charge of the vehicle's accumulator in case the vehicle comprises an electronic motor or the tire pressure of the vehicle's tires. The data signal from the vehicle can also be an authentication request of an immobilizer system of the vehicle.

[0019] The receiver of the first communication module preferably is a radio frequency (RF) receiver that operates at a frequency of 315 MHz, 433, 93 MHz, 868 MHz or 915 MHz. Alternatively, the receiver of the first communication module is a low frequency (LF) receiver operating at a frequency of 125 kHz. Modern automotive vehicle commonly comprise at least one transmitter operating at one of these frequencies.

[0020] In a particular embodiment of the identification device according to the invention, the second communication module comprises transmitter for wirelessly transmitting a data signal to the control device. If the first communication module of the identification device also comprises a receiver for wirelessly receiving a data signal from the vehicle, the identification device supports bi-directional communication between the control device and the vehicle. Therefore, the identification device can forward data signals from the vehicle (concerning for instance the lock status of the vehicle, the gas level of the vehicle in case the vehicle comprises a combustion engine, the state of charge of the vehicle's accumulator in case the vehicle comprises an electronic motor or the tire pressure of the vehicle's tires) to the control device. The control device then provides the user of the device with this information, or with additional information calculated from or extracted out of the received data signal(s). In this configuration the identification device can operate as a bi-directional gateway device between the control device and the vehicle.

[0021] The transmitter of the second communication module preferably is a near field communication transmitter operating at a frequency of 13,56 MHz. This frequency allows for a communication with NFC-enabled control devices, such as NFC-enabled mobile phones.

[0022] In an advantageous embodiment of the identification device according to the invention, the second communication module is configured for transmitting a data signal to the control device upon receipt of a data signal from the vehicle at the first communication module. This allows for transmitting a data signal from the identification device to the control device without having a user interface on the identification device.

[0023] The microcontroller of the identification device is preferably configured for prompting the second communication module to initiate the transmission of the data signal to the control device upon receipt of the data signal of the vehicle at the first communication module.

[0024] In a preferred embodiment of the identification device according to the invention, the energy supply unit comprises an energy storage device for intermediately storing electrical energy for providing the first communication module with electrical energy. The energy storage device preferably comprises at least a capacitor, a supercapacitor and/or a rechargeable cell.

[0025] One embodiment of the identification device according to the invention comprises a liquid tight housing, wherein all electrical components of the identification device, such as the first communication module and the second communication module, are disposed within the housing. The liquid tight housing allows for a usage of the identification device in moist or humid environments. Therefore, the identification device can be, for instance, attached to a mobile device, such as a mobile phone, which might be exposed to high atmospheric humidity or even rain. An advantageous embodiment the housing of the identification device is made by resin transfer molding (RTM).

[0026] Another embodiment of the identification device according to the invention comprises a monitoring unit configured for monitoring the state of charge of the energy storage device. The monitoring unit is configured for either initiating communication with the control device or for initiating the transmission of the remote control signal to the vehicle depending on the state of charge of the energy storage device. By means of the monitoring unit the identification device is able to decide whether the state of charge of the energy storage device is sufficient to completely transmit the remote control signal to the vehicle. In case the state of charge is sufficient to completely transmit the remote control signal, the transmission of the remote control signal by means of the first communication module is initiated. In case the state of charge is not sufficient to completely transmit the remote control signal, communication with the control device is initiated. Then a data signal requesting a wireless communication signal from the control device for generating the missing electrical energy out of the wireless communication to transmit the remote control signal to the vehicle is transmitted to the control device. When the state of charge subsequently takes a level sufficient to completely transmit the remote control signal, the transmission of the remote control signal by means of the first communication module is initiated. This might lead to a delay between transmitting the command signal from the control device to the identification device and transmitting the remote control signal from the identification device to the vehicle, but the remote control function is maintained even when the state of charge of the energy storage device is not sufficient to completely transmit the remote control signal to the vehicle at the moment of transmitting the command signal from the control device.

[0027] In a preferred embodiment of the identification device according to the invention, the transmitter of the first communication module, the receiver of the first communication module, the transmitter of the second communication module, the receiver of the second communication module, the microcontroller and/or the detector device are incorporated in an application-specific integrated circuit (ASIC).

[0028] The object of the invention is also solved by means of an remote control arrangement for a vehicle, in particular an remote access control arrangement for a vehicle according to claim 10.

[0029] The remote control arrangement according to the invention comprises an identification device according to one of the claims 1 to 9, a control device configured for wireless communication with the second communication module of the identification device, and a vehicle-side receiving unit configured for wirelessly receiving the remote control signal from the first communication module of the identification device.

In an even more preferred embodiment of the remote control arrangement according to the invention, the identification device is attached to the control device, for instance to the backside of a control device being formed as a mobile phone. Alternatively, the identification device is disposed within the control device and/or is integrated within a Secure Digital (SD) card.
