ABSTRACT:
To prevent wheel spinning in reverse gear on a slippery road surface the electronic control system of the present invention transmits signals representing the states of a reverse range detecting switch and a winter mode switch to a microcomputer, and output signals from the microcomputer are transmitted to an engine control computer which in turn, sends ignition period delay angle signals to the spark timing controller, and the output torque of the engine is thereby reduced. When the output torque of the engine is reduced, the driving power to the wheels is decreased and slippage is reduced in reverse start on a low coefficent of fuction .mu. path.
