Abstract
To provide a motor controller that can achieve sharing of hardware resources, saving space in the entire vehicle, improving stability, and reducing failure rate. [Solution] The parking control unit, differential lock control unit, and motor control unit are integrated onto a control circuit board and controlled using the same microprocessor, thereby saving the layout space and hardware resource costs of the entire vehicle. Closed-loop control of the parking function is achieved by adding a control circuit between the position feedback collection means and the parking control unit. Closed-loop control of the differential lock function is achieved by adding a control circuit between the state feedback collection means and the differential lock control unit. This achieves technical effects such as sharing of hardware resources, improving stability, and reducing the failure rate.
