AI Technical Summary

Technical Problem

The prior art cannot automatically judge the road environment, resulting in the inability of vehicles to ensure excellent performance in various road environments, reducing the driving experience.

Method used

By obtaining the first-level road type of the vehicle's current road, the vehicle is controlled to enter the corresponding driving mode, and on this basis, the road type is gradually subdivided through wheel speed information and vehicle dynamic information, and the target third-level road type is determined, and the compensation parameters of each electronic control system are adjusted.

Benefits of technology

It realizes that the vehicle can maintain excellent performance in various road environments, without the driver manually judging the road type and choosing driving mode, improving the driving experience.

Abstract

The present invention provides a vehicle control method and device, which relates to the field of vehicle technology. The method includes: obtaining the primary road type of the road currently traveled by the vehicle; controlling the vehicle to enter a driving mode corresponding to the primary road type, wherein the driving mode includes control parameters of each electronic control system of the vehicle; in this driving mode, obtaining the wheel speed information and vehicle dynamic information of the vehicle; obtaining the target secondary road type from the secondary road types included in the primary road type according to the wheel speed information; obtaining the target third-level road type from the third-level road types included in the target secondary road type according to the vehicle dynamic information; determining the compensation parameters for each electronic control system according to the target third-level road type; and adjusting the control parameters of the corresponding electronic control system based on the compensation parameters of each electronic control system. In the present application, the road type is automatically subdivided multiple times and the control parameters of each electronic control system of the vehicle are fine-tuned accordingly, so that the vehicle can maintain excellent performance in various road environments.
