This paper presents a longitudinal control algorithm for a smart cruise control with virtual parameters in multiple transitions by a driver and traffic conditions. The object is to achieve driver's comfort and smooth transition with collision prevention for safety in various driving situations. The proposed algorithm consists of an in-path target selection, a generation of virtual parameters, and longitudinal controller for smart cruise control. The in-path target selection algorithm selects an important target which moves on the driving direction of subject vehicle. In addition, it provides the information in order to drive a subject vehicle smoothly and improve safety in various traffic transitions. Finally, smart cruise control controller with virtual parameters computes the desired acceleration. In order to reduce effects of discontinuous changes caused by traffic conditions or drivers such as time gap, set speed, and automation switching, the virtual parameters are applied to longitudinal control algorithm for smart cruise control. The performance and safety benefits of the proposed smart cruise control system are investigated via simulations using real vehicle driving data.
