PROBLEM TO BE SOLVED: To provide a power steering system with improved reliability of a power supply line.SOLUTION: A power steering system 100 includes: a motor 130 having two multi-phase coils; a power supply part 110 having two power supplies 111, 112, for supplying each phase of the motor 130 with power; and a control part 120 having inverters 121, 122 disposed respectively corresponding to the multi-phase coil and detecting a current flowing through a power supply line from the power supply part 110 to the motor 130, for controlling the power supplied to each of the coils. Further, when simultaneously stopping the power supply to one of the multi-coils and supplying power to the other of the multi-coils, the control part 120 detects a failure in the power supply line on the basis of a current.

    【課題】電力供給ラインの信頼性を向上させたパワーステアリングシステムを提供する。【解決手段】二つの多相コイルを含むモータ130と、二つの電源111,112を含み、モータ130の各相コイルへと電力を供給する電源部110と、多相コイルに対応して設けられ、電源部110からモータ130への電力供給線に流れる電流を検出するインバータ121、122を含み、各相コイルに対して供給される電力を制御する制御部120と、を備えたパワーステアリングシステム100であって、制御部120は、一方の多相コイルへの電力供給を停止して、他方の多相コイルへの電力供給を同時に行う際に、電流に基づいて、電力供給線の不良を検出する、パワーステアリングシステム100。【選択図】図1
