Digital Image Processing Assisted Active Air Suspension in Automotive Vehicle

Since the last two decades, the Active Suspension system has been a major area of research in the automobile sector. An Active Suspension consists of a mechanical spring, a damper, and actuator which is operated by an algorithm using sensor feedback. Spring damps the static load of the sprung mass and force actuator gives the required reactive force to minimize or absorb deflection caused by road irregularities. These irregularities are monitored by image processing to provide prior information of road due to which suspension act as active suspension. Vehicle sprung and unsprung mass is differentiated as a full car model. This reviews the quarter car MATLAB SIMSCAPE model of the vehicle. It also involves only the parameter values and not mathematical equations, which makes it easier to understand the behavior of the suspension body. After a detailed study, it is assumed that vehicle suspensions are inclining towards the active suspension system due to their precise and adaptable force control, lower maintenance, high ride quality, simple design and tractable performance.
