Control method and device of thermal management system in vehicle, vehicle

Abstract

The present invention relates to the field of vehicle technology, and specifically discloses a control method and device for a thermal management system in a vehicle, and a vehicle. The method includes: after obtaining multiple control parameter groups and the real-time working conditions of the vehicle at the current moment, multiple target prediction values ​​of the vehicle in a prediction time domain after the current moment can be predicted based on the real-time working conditions and multiple control parameter groups, and each target prediction value is used to characterize the energy consumption of the thermal management system of the vehicle under a corresponding control parameter group, and whether the temperature rise of the battery in the vehicle meets the temperature rise requirement. Since the thermal management system is controlled according to the control parameter group corresponding to the smallest target prediction value among the multiple target prediction values ​​in the prediction time domain, it can be ensured that the energy consumption of the thermal management system in the prediction time domain is the lowest, and the temperature rise of the battery meets the temperature rise requirement, thereby ensuring the energy consumption of the thermal management system in the prediction time domain is the lowest while ensuring the battery life.
