The vehicle controller comprises a controller shell and a water storage tank, the outer surface of the controller shell is fixedly connected with heat-dissipating metal strips, the side wall of the controller shell is fixedly connected with a first fixed mounting block and a second fixed mounting block, connecting line stretching-out holes are formed in the back part of the controller shell, the bottom of the controller shell is fixedly connected with a connecting plate, and the connecting plate is provided with water-permeable holes and further connected with a control device; and the water storage tank is fixedly connected to the lower surface of the connecting plate, an air inlet and an air outlet are formed in the side wall of the water storage tank, a cavity is formed inside the water storage tank, a cooling and heat-dissipating device is fixedly mounted inside the cavity, and the bottom of the water storagetank is fixedly connected with a rubber damping pad.

Description

Technical field [0001] The invention relates to the technical field of control devices, in particular to a complete vehicle controller for a pure electric vehicle. Background technique [0002] As the core control unit of a pure electric vehicle, the vehicle controller needs to collect the driver's operating awareness (start switch, accelerator pedal, brake pedal, etc.), and combine the status of each subsystem of the powertrain to output air conditioning switch signals and brake switches Signal, electric heater, defroster and other switch signals are used to control various functions of the whole vehicle, and output vehicle speed signal, torque speed signal, water temperature signal, SOC signal to the vehicle instrument, so that the driver can clearly know the vehicle is driving In order to drive the car efficiently and safely, the vehicle controller integrates automotive electronics, networking, informatization, intelligence and other control technologies. With the development ...
