Hybrid vehicle cooling system and hybrid vehicle

Abstract

The invention provides a hybrid vehicle cooling system and a hybrid vehicle, which belong to the field of complete vehicle cooling. The cooling system includes an engine cooling circuit, a transmission cooling circuit, and a battery module cooling circuit; each cooling circuit can communicate with each other through a thermal management module; and The thermal management module is connected to the radiator; the thermal management module judges the driving status of the vehicle by monitoring the status signals of the battery module, engine and transmission, determines the preset signal, and then corrects it according to the measurement results of each temperature sensor to determine the output signal. Adjust the cooling water flow of each cooling circuit. The invention integrates the cooling circuit of the engine, the cooling circuit of the transmission and the cooling circuit of the battery module for unified control, effectively utilizes the heat load of the battery module, provides the temperature when the engine and the transmission are started, reduces the emission and fuel consumption of the whole vehicle, and at the same time , by independently controlling each cooling circuit, the heat loss of the whole vehicle is reduced, and the reliability of the whole vehicle is improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle cooling, and more specifically relates to a hybrid vehicle cooling system and a hybrid vehicle including the hybrid vehicle cooling system. Background technique [0002] The traditional vehicle cooling system is usually divided into engine cooling system and transmission cooling system, in which only the engine cooling system is applied for thermal management, but the transmission cooling system is not applied for related thermal management, and comprehensive control cannot be performed, thus causing the heat of the transmission Losses reduce the reliability of the transmission components, causing the cooling system of the vehicle to fail to achieve the best working mode, increasing the fuel consumption and emissions of the vehicle. [0003] As environmental protection measures around the world become more and more stringent, and in the face of increasingly stringent regulations on fuel consumptio...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a hybrid vehicle cooling system to solve the problem that the traditional vehicle cooling system in the prior art cannot meet the cooling requirements of the battery module and the engine under different working conditions due to separate control, and cannot meet the needs of the entire vehicle. Equilibrium cooling of the car, not applicable to technical problems of hybrid cars
