Abstract

The invention relates to the technical 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 target cooling importance degree corresponding to the detected temperature and the temperature change rate, wherein the cooling importance degree indicates an importance degree of cooling the heating component of the vehicle; determining a corresponding cooling request level based on the detected temperature, the temperature change rate and the determined target cooling importance degree; and based on the detected vehicle running speed and the determined cooling request level, controlling a heat dissipation component to execute a heat dissipation action of a corresponding heat dissipation amplitude, wherein the heat dissipation amplitude is in positive correlation with the running speed of the vehicle and the cooling request level. Therefore, the risk that the heating component is burnt down due to the fact that the temperature rises too fastduring high-speed driving and is not reduced in time is avoided, and safe heat management on important heating components in the vehicle heat dissipation control process is guaranteed.

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...
