Abstract:
A vehicle steering apparatus 1 includes an EPS actuator 17 and an EPS ECU 18 that controls the EPS actuator 17. The EPS actuator 17 applies an assist force that assists a steering operation. A microcomputer 43 of the EPS ECU 18 determines 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 microcomputer 43 reduces a damper compensation current command Idp* (Idp**), which is a damper compensation component for attenuating a steering wheel turning speed ωs.
