The adaptive cruise system needs to meet the acceptance conditions of the vehicle manufacturer before mass production. One of the crucial evaluation scenarios is cut-in, especially when the distance between the target vehicle and the ego vehicle is close and the relative speed has little difference, or the vehicle in front suddenly brakes. In this paper, the desired acceleration and jerk of the adaptive cruise system are calculated using kinematic equations. The ego vehicle reaches the state of the target vehicle after a period of predicted time, where the predicted time is determined by the relative speed and distance between the two vehicles. To improve the subjective experience of the driver in the cut-in scene, the authors propose a fuzzy logic correction strategy based on the duration-distance of the target vehicle, which changes the trend of acceleration by reshaping the jerk. Cut-in simulation and real-vehicle test results show that this strategy can reduce the discomfort caused by rapid acceleration changes to the driver under the premise of ensuring the safety of the ego vehicle.
