The provided paper introduces an innovative approach to Adaptive Cruise Control (ACC) systems, emphasizing safety, comfort, and efficiency. Also, the proposed ACC model surpasses traditional longitudinal velocity control by integrating lateral motion and surface condition considerations. The proposed control strategy uses a new tail-following approach with the implementation of a new throttle valve controller which results in a smoother deceleration with an average of 40 percent decrease in maximum deceleration value while following other vehicles. Also, the implementation of brakes is minimized to lower the overall energy waste in vehicle motion. This approach helps the vehicle to stay laterally stable by limiting the lateral acceleration of the vehicle. Based on various studies, 0.75 of gravitational acceleration is set as the lateral acceleration limit. While turning, if the lateral acceleration tries to surpass the limit, the brakes will be employed to maintain both safety and comfort for the passengers. Through various analyses and testing, the model demonstrates superior performance, offering a holistic solution to enhance driving safety, passenger comfort, and overall fuel efficiency. The research signifies a notable advancement in ACC technology, establishing a connection between vehicle dynamics and adaptive control algorithms. The unique contribution lies in the incorporation of lateral acceleration and surface condition factors, making the ACC system versatile in addressing real-world driving challenges.
