摘要： An electric power steering control apparatus can limit a motor impression voltage thereby to maintain an appropriate motor output even upon occurrence of a failure of a motor current detection circuit or a motor current feedback control system. The apparatus includes a motor that generates an assist force to the steering system, an input processing section that takes in a steering torque signal from a torque sensor, an output processing section that drives the motor, and a processing unit that provides an instruction to the output processing section based on the steering torque signal. The processing unit includes an impression voltage calculation section that calculates an amount of operation to the motor in accordance with the steering torque signal, and an impression voltage limiting section that limits the impression voltage to predetermined limit values or less corresponding to the direction of the steering torque signal.
