ABSTRACT:
An IC engine is connected via a clutch with a change-speed transmission. A sensor responding to a gear selection informs the electronic control circuitry in which gear the vehicle is traveling. The rotary part of a tachometer is provided at the output of the transmission and is in cooperation with the sensor part of the tachometer, which feeds a signal to the electronic control circuitry. A universal joint shaft runs from the output of the transmission to the axle transmission, which is connected via the axles to the drive wheels. The rotary tachometer elements, connected with the drive wheels, are in cooperation with the tachometer sensors, whose output signals are supplied to the electronic control circuitry and compared therein with a calibration value. Such comparison determines the optimum clutch engagement time for the respective travel and loading condition of the vehicle. The rotary tachometer elements are in cooperation with the sensor parts of the tachometers and by making a comparison with the signals of the sensors the electronic control circuitry is able to ascertain the condition of the road surface as for instance dry or icy. The output of the engine is provided with a tachometer sensor for cooperation with a tachometer rotary element and at the transmission input there is a tachometer sensor so that the quotient of the output values thereof in cooperation with the torison of the drive train determines the clutch engagement time when driving over obstacles.
