Optimum Throttle and Braking Control Algorithm of Adaptive Cruise Control

Safety, ride comfort, and efficiency are the three main parameters in the quality of an advanced driver assistance system. In this research, a new adaptive cruise control strategy is proposed for the development of this module concerning the passengers’ comfort, safety, and the vehicle’s energy efficiency. For further and deeper studies, a Matlab/Simulink dynamics model which includes five subsystems for different actions is designed and simulations are performed based on this model. By optimizing the inputs of the system, namely: brake power, brake control initiation distance, and throttle control initiation distance in various driving scenarios, the control strategy performs in the most optimum way. This adaptive cruise control algorithm is capable of covering the safest distance in a given time, performing braking at the minimum distance, and consuming lesser energy in comparison with conventional models. The jerk and acceleration in the cabin are continuously kept in the comfort zone.
