A review on various control functions in adaptive cruise control systems

The use of driver assistance systems in cars is increasing since it helps the driver and reduces his/her activities and fatigue. Among these systems, the Adaptive Cruise Control (ACC) system with longitudinal dynamic automatic control is at the center of attention. With such automation, the role of the driver changes from an operator to a supervisor. Therefore, providing safety and passenger comfort in these systems is of particular importance. It should be noted that ACC can greatly affect traffic flow and can perform better than a human driver. In this paper, various control functions will be examined focusing on their application in the ACCs control section. By analyzing the advantages and disadvantages of each of the studied functions, their effects on various components such as safety and comfort of vehicle passengers are studied. Moreover, the ACC sensitivity road and weather conditions are also addressed. At the end, the horizons ahead of this topic are presented which helps to improve the past works as much as possible.
