Abstract

본 발명은 차량용 능동 현가장치에 관한 것으로서, 특히 종래 수동 현가장치 차량에서 발생하는 승차감 향상과 안정성 향상이 서로 상충되는 설계사양에서 발생하는 한계에 대해 차량용 현가장치에 비례 압력 제어밸브를 설치하여 각 유압 액튜에이터의 압력을 연속적으로 제어 함으로서 주행상태에 따라서 발생하는 진동을 억제하여 차량을 최대한 수평으로 하여 승차감을 향상시키고, 선회시 및 제동시, 조향시 각 유압 액튜에이터의 압력을 연속적으로 제어하여 차량 자세제어 및 조종성 및 안정성을 동시에 개선하면서 가, 감속시 또는 조향이나 선회시 차량 자세변화를 작게하여 차량의 운동특성을 최적화할 수 있도록한 차량용 능동 현가장치에 관한 것이다.The present invention relates to an active suspension device for a vehicle, and in particular, each hydraulic pressure is provided by installing a proportional pressure control valve on a vehicle suspension device against a limit that arises from a design specification in which a ride comfort and stability improvement that occur in a conventional passive suspension vehicle are in conflict with each other. By continuously controlling the pressure of the actuator, it suppresses the vibration generated according to the driving condition to make the vehicle as horizontal as possible to improve the riding comfort, and continuously controls the pressure of each hydraulic actuator during turning, braking, and steering. And it relates to a vehicle active suspension that can optimize the movement characteristics of the vehicle by reducing the vehicle attitude change during acceleration, deceleration or steering or turning at the same time improving the maneuverability and stability.
