ABSTRACT:
An overcurrent circuit interrupts energization of the electric motor of a motor vehicle electric power steering system whenever the motor current exceeds an overcurrent limit, thereby defining an overcurrent duty cycle. When the overcurrent duty cycle reaches a value indicative of motor stalling, the overcurrent limit is reduced to protect the motor and its drive circuitry during prolonged motor stalling.
