PROBLEM TO BE SOLVED: To stabilize a vehicular behavior when a vehicle travels in-turning.SOLUTION: A power steering system is incorporated in a vehicle and includes: a motor having two multi-phase coils; a power supply part, having two power sources, for supplying power to individual phase-coil of the motor; and a control part, having inverters disposed respectively corresponding to the multi-phase coils, for controlling the power to be supplied to the individual coils. Further, in a case where one power supply fails before the vehicle travels in turning, the control part causes the vehicle to travel in turning, with the power minimized.

    【課題】旋回走行中の車両における車両挙動を安定化させること。【解決手段】二つの多相コイルを含むモータと、二つの電源を含み、前記モータの各相コイルへと電力を供給する電源部と、前記多相コイルに対応して設けられるインバータを含み、前記各相コイルに対して供給される前記電力を制御する制御部と、を備えた、車両に搭載されるパワーステアリングシステムであって、前記制御部は、前記車両が旋回走行前に、一方の電源が故障した場合、前記電力が最小となるように、前記車両を旋回走行させる、パワーステアリングシステム。【選択図】図1
