According to the technical scheme, the inner cavity of the ECU is communicated with the cockpit, and air expansion (pressure rise) caused by heat generated by system operation is balanced. In the technical scheme, ventilation of the ECU is realized through the ventilation holes in the HCU valve body and the cockpit, rather than the ventilation holes being arranged on the ECU shell and covered by a waterproof ventilation film. The beneficial effects are as follows:
1. The waterproof breathable film and the corresponding welding structure and welding and testing equipment thereof are canceled, the ECU shell structure is simplified, and the cost is greatly reduced;
2. The whole system does not have a relatively weak part of a waterproof breathable film, and the waterproof grade is greatly improved.
