Abstract
A device is described for determining and/or controlling the operating data of automotive vehicles, particularly for controlling the velocity of vehicles with internal combustion engines and electric transmission of the position of the gas pedal to an electric setting element which is connected to the throttle valve or the displacement device of the injection pump, the device having a measuring device for determining shunt resistances to the electric position transmitter which is connected to the gas pedal and the throttle valve. Such shunt resistances (leak resistances) detrimentally affect the desired precise relationship of the position of the gas pedal to the position of the throttle valve.
