Abstract

본 발명은 전자제어 현가장치에 관한 것으로, 특히 차량의 제동 작동시나 후진시에 탑승자의 쏠림현상을 방지하도록 현가장치의 감쇠력을 자동으로 조절하는 전자제어 현가장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronically controlled suspension, and more particularly, to an electronically controlled suspension that automatically adjusts the damping force of the suspension so as to prevent the occupant from tipping during braking or reversing of the vehicle.

이와 같은 본 발명의 차량용 전자제어 현가장치에서는 차속감지센서, 제동동작감지부를 구비하고, 제어부에 의해 스프링상수와 감쇠력을 가변시켜 현가장치의 감쇠력을 조절하는 차량용 전자제어 현가장치에 있어서, 상기 제어부에 접속되어 차량의 후진 시점을 감지하는 후진지시등 작동 감지부를 구비하여 차량의 속도와 제동작동여부 및 후진지시등 작동여부에 따라 현가장치의 감쇠력을 자동제어 되도록 한 것이다.The vehicle electronically controlled suspension device of the present invention includes a vehicle speed sensor and a braking motion detection unit, and in the electronically controlled suspension device for a vehicle in which a spring constant and a damping force are varied by a control unit to adjust the damping force of the suspension system. It is connected to the reverse direction indicator operation detection unit for detecting the reverse time of the vehicle to automatically control the damping force of the suspension according to the vehicle speed, braking operation and whether the reverse direction indicator operation.
