The invention discloses a motor controller. The motor controller comprises a shell and a control circuit board arranged in the shell, the parking control unit, the differential lock control unit and the motor control unit are integrated on the control circuit board and controlled by the same microprocessor, so that the whole vehicle arrangement space and the hardware resource cost are saved; a control loop between the position feedback acquisition unit and the parking control unit is added, so that closed-loop control of the parking function is realized; a control loop between the state feedback acquisition unit and the differential lock control unit is added, so that closed-loop control of the differential lock function is realized; therefore, the technical effects of sharing hardware resources, improving the stability and reducing the failure rate are achieved.
本申请公开了一种电机控制器,包括:壳体以及设置在壳体内部的控制电路板;通过将驻车控制单元、差速锁控制单元、电机控制单元集成于控制电路板,并使用同一微处理器进行控制,节约了整车布置空间和硬件资源成本;通过增加位置反馈采集与驻车控制单元之间的控制回路,实现了驻车功能的闭环控制;通过增加状态反馈采集与差速锁控制单元之间的控制回路,实现了差速锁功能的闭环控制;由此实现了共享硬件资源,提高稳定性、降低失效率的技术效果。
