Abstract (en)
[origin: EP0298888A1] The present invention relates to a method for collecting and reading data for analysing the driving of a road vehicle by means of two transmitters, one connected to any rotary member upstream of the clutch and the other connected to any member located downstream of the gearbox, and two electrical contacts, one connected to the brake pedal and the other to the fuel feed, so that, depending on the variation in the number of pulses per second dependent on the engine speed, said pulses, when they pass at the frequency of one of the predetermined reference marks, cause the simultaneous sequential recording of five parameters on a recording support, in particular at 1 the reference mark of the frequency at a predetermined speed of the engine, at 2 the instantaneous number of revolutions per second of the transmission, at 3 the action of braking or non-braking, at 4 the feed or non-feed of fuel, at 5 the time elapsed in seconds in relation to entry in the recorder of the recording support, the latter causing at 6 the inscription of the date, hour, minutes and seconds of the present time, and intermediately at 7 the minutes elapsed between the recording of the sequences are recorded. <IMAGE>
