Automatic Ground Clearance Adjustment System

The handling of vehicle depends upon the various parameters centre of gravity of the vehicle is one of them. For better handling of the vehicle we need to keep centre of gravity as low as possible. Whereas a sedan car or hatchback has to run on smooth roads as well as on rough terrains sometime with its fixed lower ground clearance which tends to create dents on the bottom portion the car. In both cases we need an adjustable ground clearance system in the vehicle to have optimum performance. Most commercial vehicles currently on the market are still equipped with a passive suspension system, while some luxury brands may already use an adaptive suspension. Active suspension systems on the other hand are rarely found, however, they offer great opportunities to close the gap of the well-known trade-off between ride comfort and handling. Besides that, they can also be used to mitigate single event disturbances, an objective of the USA army as announced in a solicitation which initiated and motivated this research. In addition to that, several studies were found stating the impact and danger of potholes and their impact on the vehicle and passenger. “Pneumatic jack� fabricated model consists of a pneumatic control valve which regulates the air flow and double acting cylinder used as a jack which performs lifting. Thus the car is lifted using jack and the problem related to tyres such as puncture types, tyre replacement and wheel balancing can be resolved with less effort and time.
