Intelligent active control system design for improving vehicle performance and safety

Active control system has an indispensable effect on vehicle stability,performance and safety.so,design and implementation of control systemsis one of the most effective methods,which could considerably enhance the vehicle stability and controllability.motion control,stability maintenance and ride comfort improvement are fundamental issues in design of active control systems. in this paper,intelligent vehicle systems are introduced and in order to optimize the vehicle safety smart control systems such as smart airbag by gps,electronic stability program (esp),traction control system (tcs) and active suspension systems are developed for passenger vehicles. also advanced smart highways technologies with communication systems are presented. these control systems used path,steering angle and throttle as a input to control vehicle velocity,acceleration and yaw rate to improve vehicle safety in sever manouvers and situations. application of these systems results in improving safety,traffic flow and contrallability of vehicle. simulation results demonstrate the effectivness of developed active control systems in vehicle safety and crash aviodance.
