Problems solved by technology
[0004] However, the disadvantage of this traditional control method is that the mathematical model for predicting the relevant units of the electric vehicle is fixed and cannot adapt to all driving scenarios that appear in the actual driving process.
In addition, because it is based on navigation and satellite positioning data, the accuracy of data acquisition is very high, otherwise there will be problems of overheating or insufficient cooling of the relevant units of the electric vehicle

The present invention provides a cooling control system and method for a motor vehicle, especially to an electric vehicle. The system comprises a server unit and a plurality of N client units, wherein N is larger than or equal to 1, the server unit is in mutual data connection with the N client units in a wireless network, the N client units can be respectively arranged on N motor vehicles, each client unit can collect and store calculation input data which can be used for evaluating the temperature of a unit required being cooled on the corresponding motor vehicle in real time, each client unit can also collect and store the temperature data of the unit required being cooled in real time, each client unit can also predict the temperature data of the unit required being cooled at a future moment by using the collected calculation input data based on a predictive mathematical model determined by the server unit (200), and each client unit is capable of selectively cooling down the units requiring being cooled ahead of time based on the predicted temperature data.
Description
technical field [0001] The present application generally relates to cooling control systems and methods for any components in motor vehicles, particularly electric vehicles, that require cooling. Background technique [0002] Electric vehicles are gaining popularity due to environmental reasons and increasingly stringent emissions regulations. For electric vehicles, thermal control is a very important topic. For example, during the operation of electric vehicles, units such as battery packs, battery management units, inverters, communication modules, gearboxes, and motors will continuously generate a large amount of heat. In the event of overheating, mandatory safety measures are usually taken, such as reducing the operating power of the corresponding components or forcibly stopping the operation of the electric vehicle to avoid component failure. That is to say, if the temperature rise of the components cannot be accurately predicted in advance and cooled accordingly, the...
