Abstract

The invention relates to the field of vehicle heat dissipation, and provides a vehicle heat dissipation control method and system. The vehicle heat dissipation control method comprises the steps of detecting the temperature of a heating component of a vehicle, the temperature change rate, and the vehicle running speed; determining a corresponding target cooling request level based on the detectedtemperature and the temperature change rate; and controlling a heat dissipation component to execute a heat dissipation action of a corresponding heat dissipation amplitude based on the detected vehicle running speed and the determined target cooling request level, wherein the heat dissipation amplitude is in positive correlation with the vehicle running speed and the target cooling request level.Therefore, the vehicle speed is also considered in addition to the temperature and the temperature change rate of the heating component in the heat dissipation process, heat dissipation treatment should be conducted even if the temperature is low and the driving speed is high, and the risk that the heating component is burnt down due to the fact that cooling is not conducted in time when the driving temperature rise is too high can be avoided.

Description

technical field [0001] The invention relates to the technical field of vehicle heat dissipation, in particular to a vehicle heat dissipation control method and system. Background technique [0002] At present, the vehicle mainly drives the heat dissipation components installed in the vehicle, such as water pumps, so as to realize the heat dissipation management of the vehicle. Its function is to make the power components, power components and control components work at the limit operating temperature designed by the component supplier Within the range, the passenger compartment can meet the comfort requirements and the energy consumption of the thermal management components of the vehicle can be optimized. [0003] At present, some related technologies propose to directly control the rotational speed of the water pump according to the temperature and the rate of temperature change, so as to achieve a balanced control between energy saving and temperature control. However, t...
