Cooling system of hybrid vehicle, and hybrid vehicle

Abstract

The invention provides a cooling system of a hybrid vehicle, and the hybrid vehicle, and belongs to the field of vehicle cooling. The cooling system comprises an engine cooling loop, a transmission cooling loop and a battery module cooling loop; all the cooling loops can communicate with one another through a thermal management module and are connected with a radiator through the thermal management module; and the thermal management module judges the driving state of the vehicle by monitoring states signals of a battery module, an engine and a transmission, a preset signal is determined, thencorrecting is conducted according to measurement results of all temperature sensors, an output signal is determined, and the cooling water flow of all the cooling loops is adjusted. The engine coolingloop, the transmission cooling loop and the battery module cooling loop are integrated to be controlled in a unified mode, the thermal load of the battery module is effectively utilized, the temperature during starting of the engine and the transmission is provided, and emission and fuel consumption of the vehicle are lowered; and meanwhile, the heat loss of the vehicle is lowered by independently controlling all the cooling loops, and the reliability of the 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
