Abstract
When a steering speed reaches a steering speed determination threshold, a steering speed gain is set to '0'. As a result, a final basic assist controlled variable becomes '0', and application of an assist force to a steering system is stopped. Therefore, repetition of so-called reverse assist that is a cause of occurrence of an unintended steering behavior, such as self-excited vibration, is stopped. Accordingly, the steering behavior is improved.
