Embodiment approach

[0034] figure 1 A diagram illustrating a method for controlling a suspension system according to an embodiment of the present invention.

[0035] refer to figure 1 , you can select the control mode of Electronically Controlled Suspension (ECS) and Active Roll Stabilizer (ARS) according to the vehicle's straight-line driving, steering and road conditions.

[0036] The ride impression or operation of the vehicle may be controlled according to modes classified into straight-line driving, normal steering, and emergency steering. That is, there is no need to control the vehicle operation during straight running, and it is necessary to control the vehicle operation during normal steering and emergency steering.

[0037] In addition, the ride impression or operation of the vehicle can be controlled according to road conditions. The ECS or ARS of the vehicle may determine whether the road is even or not based on whether the road input signal is generated. That is, during vehicle...

Abstract

A method for controlling a suspension system includes controlling an electronic controlled suspension device (ECS) and an active roll stabilizer (ARS) of a vehicle based on an input sensor value and a driving operation of the vehicle, the input sensor value is based on a road condition and wherein the driving operation is one of a straight driving, a normal turning, and an urgent turning of the vehicle.

Description

[0001] Cross References to Related Applications [0002] This application is based upon and claims the benefit of priority from Korean Patent Application No. 10-2014-0139294 filed with the Korean Intellectual Property Office on October 15, 2014, the inventive concept of which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to a method for controlling a suspension system, and more particularly to a technique for controlling a suspension system for ride impression and ride stability performance. Background technique [0004] Generally, a vehicle including a 4-wheel drive (4WD) device mounted thereon does not include a yaw moment for measuring the yaw moment that rotates the body to the left or right based on the center point of the vehicle, so the front and rear drive forces are simply based on the sliding of the wheels distribution and control. [0005] Therefore, there arises a problem that vehicle behavior cannot...
