Abstract: Adaptive cruise control for assessing the risk of collisions between adjacent vehicles and adjusting the distance between them to improve driving safety. An adaptive cruise control system is developed on an AIT intelligent vehicle is implemented. The vehicle's original throttle system and braking system have to be changed to create the adaptive cruise control system. By using a dc motor with a position control algorithm, the original throttle valve which is operated by a cable from the accelerator pedal is changed to the drive-by-wire System. An autopilot vehicle is considered as a solution to prevent crashes.The methodology to predict dangerous situations and change the speed automatically to avoid a crash,predicting adjacent vehicle positions can be applied on a real vehicle in the near future. The proposed method allows estimating each driver's operating characteristics and applying the estimated results to obtain the prediction of the trajectory and based on such estimation, the probability of the collision is calculated.The method detected lane changes with 99.3%, achieved trajectory prediction error of 0.066 m, speed and distance from adjacent vehicles accordingly to minimize the collision risk.
