Embodiment Construction
[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0044] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

The invention provides an automobile thermal management method and a device thereof and a computer readable storage medium, the automobile thermal management device comprises a driving system and a cooling system for cooling the driving system, and the automobile thermal management method comprises the following steps: collecting temperature information of the driving system; calculating a difference value between the temperature information and a preset temperature; acquiring corresponding parameter information according to the difference value; and adjusting the cooling efficiency of the cooling system according to the parameter information. According to the technical scheme, after the temperature information of the driving system is collected, the temperature information is compared with the preset temperature, and after the difference value between the temperature information and the preset temperature is obtained, the cooling efficiency of the cooling system is further determined through a PID algorithm; therefore, accurate control over the cooling system is improved, the situation that parts are overheated and damaged due to the fact that the cooling system cannot dissipate heat in time is avoided, and meanwhile waste of energy consumption caused by excessive cooling is avoided.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile heat management method, automobile heat equipment and a computer-readable storage medium. Background technique [0002] With the development of electric vehicles, the driving range and motor power of electric vehicles have increased, and users have stricter requirements on vehicle acceleration, charging power, and heat dissipation. With the enhanced performance of electric vehicles, the requirements for temperature and heat dissipation in the vehicle are becoming more and more stringent. Therefore, in the prior art, water cooling is usually used to achieve the purpose of thermal management in the car, but the current water cooling control is based on the look-up table method to control the duty cycle of the water pump to control the size of the water flow, which cannot achieve precise control of the size of the water flow, thus result in reduced heat dissipatio...
