Problems solved by technology

[0002] Four-wheeled vehicles (hereinafter referred to as "vehicles") usually use Grip (a cornering method to maintain the grip of the vehicle tires) when passing a curve, but when the relative speed between the vehicle tires and the ground is too large , the tire and the ground will change from static friction to dynamic friction, thus losing grip and slipping, and the vehicle will slide sideways at this time
[0003] Aiming at the problem in the related art that the drift characteristics of the vehicle can only be changed by refitting, no solution has been proposed

Abstract

The present invention provides a method and device for controlling the turning posture of a vehicle, wherein the method includes: acquiring the turning direction and turning range of the steering wheel of the vehicle through a sensor; acquiring the turning mode of the vehicle; in the turning mode, according to the The rotation direction and rotation range of the steering wheel determine the output torque of the corresponding driving wheels of the vehicle; the turning posture of the vehicle is controlled according to the output torque of the corresponding driving wheels of the vehicle. The present invention can solve the problem in the related art that the drifting characteristics of the vehicle can only be changed by refitting, and realize the change of the drifting characteristics of the vehicle by flexibly controlling the turning posture of the vehicle, thereby achieving the effect of improving user experience.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for controlling a vehicle's turning attitude. Background technique [0002] Four-wheeled vehicles (hereinafter referred to as "vehicles") usually use Grip (a cornering method to maintain the grip of the vehicle tires) when passing a curve, but when the relative speed between the vehicle tires and the ground is too large , the tire and the ground will change from static friction to dynamic friction, thus losing grip and skidding. At this time, the vehicle will slide sideways. This feature leads to a driving technique known as "drifting", which is generally seen in performance occasions and off-road races. The drifting characteristics of a vehicle depend on many factors. If a driver wants to experience different drifting characteristics, he must drive a different vehicle with exactly the characteristics he needs. [0003] Aiming at the problem in the rel...
