ABSTRACT:
A vehicle steering apparatus1includes an EPS actuator17and an EPS ECU18that controls the EPS actuator17. The EPS actuator17applies an assist force that assists a steering operation. A microcomputer43of the EPS ECU18determines whether the currently executed oversteer control (OS control) is being intensified or converged. In the OS control intensification state, in which the vehicle stability is low, the microcomputer43reduces a damper compensation current command Idp* (Idp**), which is a damper compensation component for attenuating a steering wheel turning speed ωs.
