Description
Technical Field
[0001] This invention relates to the field of vehicle thermal management technology, and in particular to a vehicle thermal management control system. Background Technology
[0002] In recent years, with the increasing global emphasis on environmental protection and sustainable energy development, electric vehicles, with their advantages such as zero emissions and low noise, have gradually become the mainstream direction of the automotive industry. However, the thermal management system of electric vehicles, as a key technology to ensure vehicle performance, safety and battery life, still faces many problems that need to be solved.
[0003] According to application number CN201810541137.6, a control method and control system for a hybrid vehicle thermal management system are disclosed, relating to the field of vehicle thermal management systems. The control method includes comparing the current remaining battery charge of the hybrid vehicle with the minimum remaining battery charge in pure electric driving mode; determining whether the hybrid vehicle's driving mode is pure electric driving mode or hybrid driving mode; determining whether the engine coolant temperature of the hybrid vehicle is greater than the minimum coolant temperature when the engine starts; if the engine coolant temperature is not greater than the minimum coolant temperature when the engine starts, determining whether the motor preheats the engine and whether the fan operates; if the engine coolant temperature is greater than the minimum coolant temperature when the engine starts, determining that the motor cools independently and the fan does not operate in pure electric driving mode. This invention solves the problem that the control method of the thermal management system in the prior art cannot quickly increase the engine temperature, resulting in low cooling efficiency of the hybrid vehicle thermal management system.
