Abstract

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.

Description

technical field [0001] The present invention relates to the technical field of vehicles, and specifically provides a vehicle control method, a vehicle control system, a vehicle-mounted control device and a vehicle. Background technique [0002] The reliability of vehicle components and functions is a crucial topic in the industry. In order to improve vehicle reliability, monitoring equipment is used to monitor the status of components or functions in real time, quickly identify and replace potentially failed parts, and improve system or Functional reliability is one of the important means in the field of vehicles. The electric drive system is the core component to ensure the work of the electric vehicle and is used to drive the electric vehicle. The electric drive system is composed of mechanical parts and electrical parts, and the reliability of the electric drive system is determined by the stability of its components. . [0003] In the current diagnostic scheme, it is n...
