The embodiment of the invention provides an electronic power steering system, and relates to the technical field of motor control. The electronic power-assisted steering system comprises a controller, a three-phase motor and at least two power supply lines. The power supply circuit comprises a first power supply circuit and a second power supply circuit; the first power supply line and the second power supply line are connected with a three-phase line of the three-phase motor; and the controller is used for distributing power for the first power supply line and the second power supply line according to the fault condition parameters of the first power supply line and the second power supply line. Even if one power supply line breaks down, the other power supply line can still be used for supplying power, the three-phase motor of the electronic power steering system can still work normally, and safety is improved.
本申请实施例提供一种电子助力转向系统,涉及电机控制技术领域。电子助力转向系统包括控制器、三相电机和至少两条供电线路;供电线路包括第一供电线路和第二供电线路;第一供电线路和第二供电线路均连接三相电机的三相线;控制器用于根据第一供电线路和第二供电线路的故障情况参数,为第一供电线路和第二供电线路分配功率。即使一条供电线路出现故障,仍然可以用另一条供电,电子助力转向系统的三相电机仍然可以正常工作,提升了安全性。
