Torque detector and controls for prohibiting the operation of an electric motor on a hybrid vehicle when the driving torque of the vehicle exceeds a predetermined value during start-up

摘要

Either the front wheels and rear wheels of a front wheel- and rear wheel-drive vehicle are driven by an engine and the other thereof are driven by an electric motor. The electric motor is operated when the vehicle starts. A driving torque detecting circuit detects a driving torque of wheels to be driven by the engine. Control circuit prohibits the operation of the electric motor when the driving torque to be detected at vehicle start-up exceeds a predetermined value.
