Embodiment Construction

[0020] The vehicle controller is one of the key components of the vehicle. As the upper management unit of vehicle electrical control, it is responsible for the controllers of key components in various systems of the vehicle, such as battery management system, motor control system, electric power steering system, electronic braking system, air conditioning and heating system, conversion system, vehicle Coordinated control among major systems such as chargers. During the driving process of the vehicle, various software or hardware problems may occur. In order to ensure the stable operation of the controller, it may cause the reset of the vehicle controller. Therefore, during the process of resetting the vehicle controller and returning to normal operation, the signals sent to other vehicle controllers through the controller area network may be interrupted or changed. When this happens, the vehicle will appear to lose power until it comes to a stop. Thus affecting the normal o...

Abstract

The invention provides a control method and device of a whole vehicle controller and a whole vehicle control method and system. The control method of a whole vehicle controller comprises a step of storing the driving parameter of a vehicle in a driving process, a step of judging whether whole vehicle controller is normally powered and initialized or is failed to trigger the initialization after controller reset according to the stored driving parameter when the whole vehicle controller of the vehicle is initialized to run, and a step of controlling the whole vehicle controller to switch to an operation state before reset when the condition that the whole vehicle triggers the controller reset due to a failure is judged. Through the control method and device of a whole vehicle controller and the whole vehicle control method and system, the stable operation of the whole vehicle controller can be ensured, at the same time the continuity of a controller operating state can be ensured, and thus the drivability of the vehicle is not affected.

Description

technical field [0001] The present invention relates to the technical field of vehicle control, in particular to a control method and device of a vehicle controller, and a vehicle control method and system. Background technique [0002] During the driving process of the vehicle, due to software or hardware problems, in order to ensure the stable operation of the controller, it may trigger the vehicle controller (Vehicle Control Unit, VCU) to reset. Therefore, during the process from reset to normal operation of the vehicle controller, the signals sent to other vehicle controllers through the Controller Area Network (CAN) may be interrupted or changed. When this happens, the vehicle will appear to lose power until it comes to a stop, thereby affecting the normal operation of the vehicle. Contents of the invention [0003] The problem solved by the embodiments of the present invention is how to prevent the operation of the vehicle from being affected when the vehicle contro...
