Problems solved by technology

This spinning phenomenon leads to the loss of engine torque, so that the traction control system (Traction Control System, TCS) that controls the engine torque is controlled to start, and it cannot make full use of the friction of the road surface, so that the turning performance of the vehicle is reduced
Furthermore, due to the occurrence of spin, the lateral friction force is reduced, and in severe cases, it will cause understeer (understeer) phenomenon

Embodiment Construction

[0027] Referring to the accompanying drawings, a vehicle turning control method according to an embodiment of the present invention will be described below.

[0028] figure 2 is a control flowchart showing a turning control method of a vehicle according to an embodiment of the present invention.

[0029] like figure 2 As shown, the turning control method of the vehicle in this embodiment may include the step of calculating the turning radius of the vehicle.

[0030] The step of calculating the turning radius of the vehicle may include receiving a lateral acceleration signal of the vehicle from a lateral acceleration sensor mounted on the vehicle, by which the turning radius of the vehicle is calculated. In addition, the step of calculating the turning radius of the vehicle may include a step of calculating the turning radius of the vehicle by receiving an angular velocity signal of the vehicle from a yaw rate sensor installed on the vehicle. The method of calculating the ...

Abstract

The invention provides a cornering control method for a vehicle and a cornering control system for the vehicle. According to one aspect of the invention, the cornering control method comprises the step of critical allowed speed difference calculation for calculating the critical allowed speed difference between inner and outer driving wheels during cornering; and a step of brake torque distribution. A preset brake torque is assigned to the inner driving wheel during cornering if speed difference measured is greater than the critical allowed speed difference.

Description

technical field [0001] The present invention relates to a turning control method of a vehicle and a turning control system for a vehicle, in particular to a vehicle capable of improving the turning performance of the vehicle by transferring the engine power lost by the driving wheel on the inner side of the turning to the driving wheel on the outer side of the turning when the vehicle is turning A turning control method and a turning control system for a vehicle. Background technique [0002] figure 1 It is a diagram showing the driving state of the vehicle when turning. like figure 1 As shown, when the vehicle 10 turns, the turning radius of the drive wheel LW on the inside of the turn is different from that of the drive wheel RW on the outside of the turn. That is, the drive wheel RW on the outside of the turn has a larger turning radius than the drive wheel LW on the inside of the turn, and therefore, the drive wheel RW on the outside of the turn needs to rotate more t...
