AI Technical Summary

Technical Problem

In existing technologies, the real-time performance and accuracy of differential lock locking are poor, which reduces the vehicle's passability and driving stability in complex road conditions, especially on separated road surfaces where the best opportunity to get out of trouble is easily missed.

Method used

By acquiring vehicle driving parameter information, including motor speed and vehicle acceleration, the system can quickly identify the road surface separation and promptly control the differential lock to lock. The mechanical or electronic differential lock limits the speed difference between the left and right wheels, ensuring that the wheel on the side with high adhesion receives sufficient driving force.

Benefits of technology

It improves the vehicle's passability and driving stability in complex road conditions, avoids wheel spin on the low-adhesion side, ensures that the high-adhesion side wheels receive sufficient driving force, and enhances the vehicle's driving performance on separated road surfaces.

Abstract

This application provides a control method, device, and vehicle. The method includes: acquiring vehicle driving parameter information, including motor speed and vehicle acceleration; determining, based on the driving parameter information, that the road surface where the vehicle is located is a separated road surface; and sending first instruction information to a first controller, the first instruction information being used to instruct the first controller to control the differential lock to lock, the first controller being located within the vehicle. Based on the above method, it is possible to efficiently identify that the vehicle is on a separated road surface and promptly control the differential lock to lock, thereby improving the vehicle's passability and driving stability under complex road conditions.
