Application of different sensors such as laser sensor or stereo camera for scanning road profile and different types of mechanical mechanism such as hydro pneumatic or hydraulic system for readjusting axles are challenges between car manufacturers. In this research, a new method is proposed for improving the vertical movement mechanism in suspension system of vehicles. The proposed method is based on vertical movement mechanism which is equipped with a monitoring system to scan the road profile for stabilizing car chassis. This system will analyze steering wheel angle, weather conditions, the distance between cars during accident and car speed in order to adjust the height of the car’s axles accordingly. Such mechanism can increase comfortability, car handling stability and safety by reducing the vertical movements.

A prototype of a vertical movement model was developed to simulate its function during different driving profiles and conditions.
