Embodiment Construction

[0020] Such as figure 1 As shown, the electronic water pump 1, the motor water jacket 2, the hybrid power controller 3, and the radiator 4 form a loop, the electronic water pump makes the coolant flow in the loop, and the fan 5 further cools the coolant flowing through the radiator. The coolant is injected through the injection port 6.

[0021] As shown in Figure 2 and Figure 3, the cooling system control module controls the electronic water pump and fan to be turned on or off according to the motor stator temperature and the inverter temperature in the hybrid controller.

[0022] The motor stator temperature is collected by the motor stator temperature sensor, the inverter temperature is collected by the inverter temperature sensor, and the collected signals are transmitted to the error processing module and the cooling system control module in the hybrid controller HCU.

[0023] The first condition for the electronic water pump and fan to work is that the system is normal a...

Abstract

The invention relates to a method for controlling a cooling system of a hybrid vehicle, which can reasonably control operating conditions of an electronic water pump and a fan, guarantee that the system is operated within a high-efficiency section, and guarantee the safety of the system. The method for controlling the cooling system of the hybrid vehicle adopts the technical proposal that the electronic water pump, a motor water jacket, a hybrid controller and a radiator form a loop; the electronic water pump makes a liquid coolant flow in the loop; and the fan performs heat dissipation on the liquid coolant which flows through the radiator. The method for controlling the cooling system of the hybrid vehicle is characterized in that a control module of the cooling system controls the on/off of the electronic water pump and the fan according to the temperature of a motor stator and the temperature of an inverter in the hybrid controller.

Description

technical field [0001] The invention relates to a control method for a cooling system of a hybrid electric vehicle. Background technique [0002] At the present stage of social development, under the situation that energy crisis and environmental pollution have become important obstacles to global development, energy-saving and environmental protection products have become a hot topic in all walks of life. In the automobile industry, people are more committed to the research and development of clean and environmentally friendly electric vehicles while improving fuel vehicles. Hybrid vehicles and pure electric vehicles are attracting more and more attention, but the power source of electric vehicles - the power battery pack is the most expensive part of vehicle production, and it is also an important factor limiting the mileage of electric vehicles, which largely depends on the development of batteries The pure electric vehicle has not made a major breakthrough in the develo...
