Abstract
A vehicle steering apparatusincludes an EPS actuatorand an EPS ECUthat controls the EPS actuator. The EPS actuatorapplies an assist force that assists a steering operation. A microcomputerof the EPS ECUdetermines 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 microcomputerreduces a damper compensation current command Idp* (Idp**), which is a damper compensation component for attenuating a steering wheel turning speed ωs.
