Abstract

The present application relates to the technical field of automobile thermal management and energy consumption evaluation, and relates to a vehicle thermal and power integration virtual simulation evaluation method, device, medium and equipment. The preset vehicle data is imported into a virtual simulation software, a vehicle model is constructed, and a thermal domain module, a power domain module, a control domain module and an evaluation domain module of the vehicle are built. The vehicle model is run in the virtual simulation software, data generated by the thermal domain module and data generated by the power domain module are input into the control domain module, the control domain module returns a control strategy to the thermal domain module and the power domain module, so that the thermal domain module and the power domain module run the vehicle model according to the control strategy. According to the evaluation domain module, the running evaluation result of the vehicle model is determined. The running process of the vehicle model is comprehensively evaluated through the evaluation domain module, so that the vehicle design scheme can achieve optimization in multiple key performance indicators, and the systematic consideration of the thermal-power coupling effect of the whole vehicle is realized.
