A vehicle thermal management control system and control method

Abstract

The invention provides a vehicle heat management control system and a control method thereof and relates to the technical field of vehicle heat management. The vehicle heat management control system comprises a heat management loop and a controller, wherein the heat management loop comprises multiple water pumps and multiple electromagnetic valves and is used for being controlled to refrigerate orheat a passenger compartment and / or a battery of a vehicle; the controller is configured to control the opening sequence, opening times and openings of the water pumps and the electromagnetic valvesin the heat management loop to adjust the refrigeration or heating of the heat management loop to the passenger compartment and / or the battery according to a detected environment and a detected working condition demand of the vehicle and guarantees the stability of the temperature of the passenger compartment when the battery begins to refrigerate or heat. According to the vehicle heat managementcontrol system, the refrigeration or heating of the passenger compartment and the battery is guaranteed, the influence of the refrigeration or heating of the battery on the temperature of the passenger compartment is also reduced, the comfort of the passenger compartment is improved, customer complaints are reduced, and meanwhile, the temperature fluctuation in the passenger compartment can be improved, and the user experience can be improved.

Description

technical field [0001] The invention relates to the technical field of vehicle thermal management, in particular to a vehicle thermal management control system and control method. Background technique [0002] As the national requirements for energy saving and emission reduction become more and more stringent, the development of new energy vehicles is getting faster and faster. In recent years, the sales volume of hybrid vehicles has been increasing. The requirements are getting higher and higher, and the thermal management system of the battery is getting higher and higher. With the development of automobile technology, fuel consumption regulations are becoming stricter, and the sales of hybrid models are currently on the rise. The national standard requires that the fuel consumption of passenger cars in 2020 should be lower than 5.0L / 100km. In order to meet this requirement, almost none of the conventional power models can To meet the requirements, various car companies h...

Problems solved by technology

When the passenger compartment is heated, if there is a demand for battery cooling at this time, the flow of heated water in the passenger compartment will decrease, resulting in a decrease in the temperature of the passenger compartment, which will increase customer complaints about comfort. Currently, the strategy used in other models is to adjust the air outlet Mitigating the effects of battery cooling or heating on the passenger compartment
