Motor controller and vehicle

The motor controller comprises an upper shell and a lower shell which are assembled together, and the lower shell comprises an upper cavity and a lower cavity which are separated by a separation plate; the transmission control processor, the control circuit board, the driving circuit board and the boost inductor are arranged between the partition plates of the upper shell and the lower shell, the boost inductor water cooler is used for cooling the boost inductor, and the control circuit board and the driving circuit board are separated by a shielding plate so as to prevent mutual electromagnetic interference; the main capacitor, the IGBT module, the IGBT module water cooler, the boost capacitor and the current sensor are arranged in the lower cavity of the lower shell, and the IGBT module water cooler is used for cooling the IGBT module. The invention further relates to a vehicle comprising the motor controller. 本申请公开了一种电机控制器，其包括：组装在一起的上壳体和下壳体，所述下壳体包括由分隔板隔开的上部腔和下部腔；设置于所述上壳体和所述下壳体的所述分隔板之间的变速器控制处理器、控制电路板、驱动电路板、
