Abstract
There have been cases wherein the program itself does not operate normally and only continues to output the monitoring pulse so that racing cannot be detected, or due to electromagnetic waves or noise a pulse signal being outputted normally is measured erroneously and a mis-detection is made. In a control apparatus of an electric power steering system for, on the basis of a current command value computed from a current detected value of a motor and a steering assist command value computed on the basis of a steering torque arising in a steering shaft, controlling the motor, which applies a steering assist force to a steering mechanism, a control apparatus of an electric power steering system characterized in that it comprises a first control part and a second control part each inputting at least a torque signal, a vehicle speed signal, the motor current detected value and a motor terminal voltage, and the motor is controlled with the first control part and the second control part.
