An OBC, a DCDC, a PDU and a main control board comprising a main control chip are integrated in the controller for the electric vehicle, the OBC, a VCU and an MCU share the main control chip, the OBC and a driving module can be controlled through the main control chip so that the functions of the OBC, the MCU and the VCU can be achieved, the driving module is used for controlling turn-on and turn-off of an IGBT, the OBC and a motor share an IGBT module, and the driving module is used for controlling turn-on and turn-off of the IGBT. The main control chip can control the on and off of the IGBT by controlling the driving module so as to control the OBC and the motor to work. Therefore, the assembly in the controller in the electric automobile is concentrated, the integration level of internal devices in the electric automobile is improved, the hardware cost of the electric automobile is reduced, CAN information interaction among the OBC, the DCDC, the PDU, the VCU and the MCU can be reduced, and the communication time is shortened. Moreover, the OBC, the DCDC, the PDU, the VCU and the MCU are integrated in the controller and can share one shell, so that the occupied volume of the electric drive controller is reduced.

    本申请公开了一种用于电动汽车的控制器,用于电动汽车的控制器中集成有OBC、DCDC、PDU和包括主控芯片的主控板,OBC、VCU和MCU共用主控芯片,通过主控芯片可以控制OBC和驱动模块,以便实现OBC、MCU和VCU的功能,其中,驱动模块用于控制IGBT的导通和关断,OBC和电机共用IGBT模组,主控芯片可以通过控制驱动模块,控制IGBT的导通和关断,从而实现控制OBC和电机工作。由此,电动汽车中的控制器内的装配集中,提高了电动汽车中内部器件集成度,不仅降低了电动汽车的硬件成本,还能够减少OBC、DCDC、PDU、VCU和MCU之间CAN信息交互,减少了通讯时间。而且,OBC、DCDC、PDU、VCU和MCU集成在控制器内部,可以共用一个壳体,降低了电驱动控制器的占用体积。
