AI Technical Summary

Problems solved by technology

[0003] However, due to the inhomogeneity of the terrain, the instantaneous PSD may change frequently, resulting in continuous changes in the terrain pattern, resulting in discomfort
In addition, frequent stops on terrain can also cause changes in the instantaneous PSD, causing instability in terrain control

Abstract

The invention discloses a vehicle control method, a control device, a vehicle and a storage medium, wherein the vehicle control method includes: acquiring the instantaneous state information of the vehicle; identifying the terrain pattern of the vehicle's driving terrain according to the instantaneous state information; recording the cumulative number of recognized terrain patterns; Determine the dominant terrain pattern according to the cumulative number of terrain patterns; determine a control strategy according to the dominant terrain pattern to control the vehicle. The vehicle control method, control device and vehicle of the present invention can improve control stability and comfort.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to a vehicle control method, a vehicle control device, a vehicle, and a storage medium. Background technique [0002] In the related technology, a terrain attribute extraction method based on wheel speed information is proposed. When the vehicle is driving on different terrains, the total power spectral density of the wheel speed can be calculated according to the wheel speed sample information collected in different situations. ((power spectral density, PSD), the size of the total power spectral density is used to characterize the mechanical properties of the terrain, therefore, the corresponding terrain control strategy can be assigned. [0003] However, due to the inhomogeneity of the terrain, the instantaneous PSD may change frequently, resulting in continuous changes in the terrain pattern, resulting in discomfort. In addition, frequent stops on the terrain can al...
