ABSTRACT:
A system having a motor operatively connected to a steering system for reducing the steering effect is provided with a steering torque sensor for detecting steering torque in the steering system during a steering operation, an alternator output level sensor for detecting the output level of an engine driven alternator, and an ignition key switch sensor. In response to the output signal of the steering torque sensor, an assist signal is provided. In response to the output level of the alternator output level sensor and the position of the ignition key switch, an engine stall condition is detected. When engine stall occurs, the output torque of the motor is controlled in response to the assist signal for a predetermined period.
