Embodiment Construction

[0012] figure 1 is a block diagram showing an apparatus using the vehicle anti-roll / yaw control method of the present invention.

[0013] The device of the present invention comprises the steering angle sensor 10 of the wheel, the yaw rate sensor 11, the lateral G sensor 12, the wheel speed sensor 13, the vehicle speed sensor 14 and the ECU (Electronic Control Unit) 15, the front shock absorber adjustment element 16 and Rear shock absorber adjustment element 17.

[0014] The wheel steering angle sensor 10 detects the steering angle of the vehicle, and then supplies the detected steering angle data to the ECU unit 15 . Also, the yaw rate sensor 11 measures the yaw rate of the vehicle, and then supplies the measured yaw rate data to the ECU unit 15 .

[0015] At the same time, the lateral G sensor 12 detects the lateral G of the vehicle, and then supplies the detected lateral G data to the ECU unit 15 .

[0016] The wheel speed sensors 13 include four wheel speed sensors prov...

Abstract

This method for controlling anti roll and anti yaw of the vehicle includes a step comparing a vehicle roll rate with a predetermined threshold roll rate and determining whether anti roll control is required or not, a step carrying out anti roll control when the vehicle roll rate is larger than the predetermined threshold roll rate, a step comparing difference between an actual yaw rate and a desired yaw rate with a predetermined threshold yaw rate and determining whether anti yaw control is required or not, and a step carrying out anti yaw control when the difference between the actual yaw rate and the desired yaw rate is larger than the predetermined threshold value. Front and rear wheel left and right dampers are simultaneously controlled to hard during anti roll control. Front wheel left and right dampers are controlled to hard and rear wheel left and right dampers are controlled to soft during anti yaw control. Consequently, ride comfort is improved and an accident due to unstable vehicle behavior is prevented.

Description

technical field [0001] The present invention relates to a method of controlling the roll / yaw (yaw) motion of a vehicle, and more particularly, to a method for controlling the resistance of a vehicle by adjusting the damping force of front and rear shock absorbers mounted on the vehicle. Method for optimizing roll / anti-yaw. Background technique [0002] Generally, a vehicle is equipped with a suspension system in order to improve its ride comfort and tire-road adhesion stability efficiency. The suspension system includes springs and buffers, ie shock absorbers. [0003] Generally, the shock absorber is mounted in parallel on a spring provided between the vehicle body and the wheel. The shock absorber absorbs the vibration of the vehicle caused by the shock acting on the spring when the vehicle is running. In other words, the shock absorber reduces the vertical kinetic energy of the spring, thereby improving ride comfort. [0004] Recently, a large number of vehicles use a...
