[0039] The existing integrated power drive system is mainly a three-in-one electric drive, which mainly includes a motor, an electric control, a reduction box and related accessories.

Wherein, the method can determine the corresponding flow request according to the temperature sensor and the system state, and the flow request is the five-gear request divided according to the pump characteristics.

[0042] Based on this, the method can determine accurate flow request based on the multi-integrated electric power driving system, so as to realize the coupling between cooling and heat transfer, realize the best flow request of the vehicle under the premise of meeting the cooling demand and heat transfer demand, and realize the best endurance mileage of the vehicle.
