A Research on Driving Performance of Vehicle Body Control using vehicle height adjustment system

Recently, premium cars include a device in the suspension that can adjust the ride height. The main function of this system is to help the vehicle pass through uneven roads by keeping the vehicle body high so that the lower part of the vehicle does not contact the road surface. In particular, the device of the air spring type improves riding comfort by adjusting the vehicle's wheel rate. The proposed system was designed to adjust the ride height by adjusting the position of the spring lower seat up and down. By modeling the machinery topology of the proposed system in detail using a dynamics tool, we would like to investigate the feasibility of implementing driving performance by controlling not only the height adjustment function but also the vehicle body Posture of the vehicle during driving.
