Embodiment Construction

[0013] The present invention will be described in detail below with reference to the accompanying drawings.

[0014] like figure 1 As shown, the control method for the hybrid vehicle cooling system provided by the present invention includes the following steps: obtaining the working state of the engine and the working mode of the air conditioner 1; collecting the temperature of the coolant in the radiator 2 of the electric part or obtaining the external temperature; Acquire the temperature of the coolant in the engine radiator 3; it is characterized in that it also includes the following steps. Whether it is in the working state and whether the air conditioner 1 is in the cooling state, the work of the cooling fan 5 and the condensation fan 4 is controlled.

[0015] In the step of obtaining the working state of the engine and the working mode of the air conditioner in the method, the information of whether the engine is in the working state can be obtained from the engine con...

Abstract

The invention provides a cooling system of a hybrid power automobile, which comprises an air-conditioner with an air-conditioner controller, a radiator of electrical parts with a temperature sensor, an engine radiator, a condensating fan and a cooling fan. The condensating fan and the cooling fan are used for reducing the temperatures at the inlet parts of a condensator and the engine radiator in the air-conditioner respectively; wherein the cooling system further comprises a cooling controller which is connected with the air-conditioner controller in the air-conditioner, the temperature sensor in the radiator of the electrical part, the cooling fan and the condensating fan respectively; The cooling controller can control the operation of the condensating fan and the cooling fan based on the operation mode of the air-conditioner, which is transmitted from the air-conditioner controller, the temperature value of the cooling liquid in the radiator of the electrical part, which is sensed by the temperature sensor, or the external temperature value which is transmitted by the air-conditioner controller, the temperature value of the cooling liquid in the engine radiator, and the operating condition of the engine. The cooling system can minimize the power consumption on the premise that the requirements for the cooling system are met.

Description

technical field [0001] The present invention relates to a cooling system and a control method, more particularly, to a cooling system and a control method of a hybrid electric vehicle. Background technique [0002] The cooling system of the existing hybrid electric vehicle usually includes: an electric part radiator, which is used to exchange heat between the cooling water and air for cooling the electric part, to cool this part of the cooling water; an engine radiator, which is used to cool the cooling engine The water exchanges heat with the air to cool this part of the cooling water; the condenser is used to exchange heat between the high-temperature refrigerant in the air conditioner and the air to cool the refrigerant. The electric part is an electric part related to the control of the electric motor, such as a motor controller, an air conditioner controller, and the like. The cooling system also includes a condensing fan and a cooling fan, respectively used to reduce ...
