Abstract: In this paper, the problem of vehicle setback control with assistant driving adaptive cruising function is analyzed, and the driving comfort is optimized by adding negative torque request decision logic tou pper controller. In the course of car-following, the linear motion smoothness of the front and rear directions of the vehicle is improved when the vehicle is controlled lengthways to decelerate, so as to achieve a smooth and comfortable subjective driving feeling, it provides an effective solution for the following vehicle development, assistant driving and adaptive cruising function tuning. With the optimization and perfection of the function and performance of vehicle assistant driving, the problem of comfort perception of intelligent driving will be better, and the technology of intelligent driving will be developed rapidly.
