VEHICLE DRIVE CONTROL SYSTEM

摘要

A control system for the transmission of a four-wheel drive vehicle which operates in accordance with the driving conditions. The transmission is arranged to transmit power from the engine directly to two main drive wheels (36a, 36b), and an electro-magnetic clutch (22) is provided for transmitting the power of the engine to drive two additional wheels. A steering angle sensor (35) is connected to a control circuit for controlling the clutch current applied to the coil (29) of the electro-magnetic clutch. The control circuit is so arranged that the clutch current is varied in accordance with the steering angle and may be cut off when the steering angle signal exceeds a predetermined level to disengage the clutch and thus to provide two-wheel drive only.
