To solve the problem of deteriorating the operability and the stability of a vehicle because the function of a steering mechanism of wheels stops when a steering motor fails in an electric power steering device which has respective independent steering mechanisms on four wheels of the vehicle.SOLUTION: Steering motors 13a, 13b, 18a, 18b of steering mechanisms 3a, 3b, 4a, 4b provided independently on four wheels of a vehicle have a redundant configuration of a three-phase duplicated motor which respectively has two sets of three-phase windings 19a, 19b, and two sets of inverters 22a, 22b for individually driving the three-phase windings.SELECTED DRAWING: Figure 2

    【課題】車両の4輪にそれぞれ独立した転舵機構を有する電動パワーステアリング装置においては、転舵モータが故障した際には当該の車輪の転舵機構の機能が停止し、車両の操縦性、安定性が低下するという課題があった。【解決手段】車両の4輪にそれぞれ独立して設けられた転舵機構3a、3b、4a、4bの転舵モータ13a、13b、18a、18bは、それぞれ2組の3相巻線19a、19bと、3相巻線を個別に駆動する2組のインバータ22a、22bとを有する3相2重化モータの冗長構成とした。【選択図】図2
