The invention relates to the technical field of vehicles, and particularly provides a vehicle control method, a vehicle control system, vehicle-mounted control equipment and a vehicle. In order to solve the problem that an existing vehicle needs to be additionally provided with a diagnosis sensor to diagnose the health degree of an electric driving system, and the cost is increased, the vehicle is provided with the electric driving system; the control method of the vehicle comprises the steps that obtained whole vehicle control parameters of the vehicle are substituted into a preset first correlation degree matrix model to obtain part temperature, namely a first temperature value; the actual temperature, namely a second temperature value, of the component of the electric drive system is obtained; the second temperature value and the first temperature value are subtracted to obtain a temperature residual value; and judging the part health degree of the electric driving system according to the temperature residual value. A diagnosis sensor is not additionally introduced, and based on a temperature sensor necessary in protection of the electric driving system, the diagnosis system has zero hardware cost, and the health condition of the electric driving system is judged according to different thermal expressions of components of the electric driving system under the same whole vehicle control parameters.

    本发明涉及车辆技术领域,具体提供一种车辆的控制方法、车辆控制系统、车载控制设备及车辆。为解决现有车辆需要额外部署诊断传感器对电驱动系统进行健康度诊断,造成成本提高的问题,本发明的车辆设置有电驱动系统,本发明的车辆的控制方法包括:将获得的车辆的整车控制参数代入预设的第一关联度矩阵模型中获得部件温度,即第一温度值;获取电驱动系统的部件的实际温度,即第二温度值;将第二温度值和第一温度值作差得到温度残值;根据温度残值判断电驱动系统的部件健康度。通过不额外引入诊断传感器并基于电驱动系统的保护中所必须的温度传感器,使诊断系统零硬件成本,在相同整车控制参数下,电驱动系统部件不同的热表现来判断其健康状况。
