The invention provides an automotive thermal management active cooling method and system and an automobile, and the method comprises the following steps: S1, loss calculation: respectively calculating first total loss and second total loss, the first total loss is calculated based on controller loss and motor loss, and the second total loss is calculated based on controller loss and motor loss; the second total loss is calculated based on the electric power input by the motor controller and the mechanical power of the electric drive system; s2, obtaining a loss result: taking a smaller value of the first total loss and the second total loss as the loss result; and S3, heat management control: the motor controller looks up a table to determine the power required by the heat management component according to the loss result, and controls the heat management component according to the power required by the heat management component. According to the invention, based on the total loss of the motor controller and the motor, the motor controller directly controls the thermal management part, so that the hysteresis of thermal management cooling can be solved, and the total loss is checked in two modes, so that the control accuracy is ensured.
本发明提供了一种车用热管理主动冷却方法、系统及汽车,其中方法包括如下步骤:S1、损耗计算:分别计算第一总损耗和第二总损耗,第一总损耗基于控制器损耗和电机损耗计算获得,第二总损耗基于电机控制器输入的电功率、电驱系统的机械功率计算获得;S2、获得损耗结果:取第一总损耗和第二总损耗的较小值作为损耗结果;S3、热管理控制:电机控制器根据损耗结果,查表确定热管理部件的所需功率,并据此对热管理部件进行控制。本发明基于电机控制器和电机的总损耗,电机控制器直接进行热管理部件的控制,由此可以解决热管理冷却的滞后性,并且,总损耗通过两种方式校核,保证了控制的精准性。
