Abstract

The invention discloses an adaptive cruise controller with lane changing auxiliary function and a working method thereof, the controller includes a sensing system, a lane change warning system, a lanechange assistance system and ACC systems, the sensing system is respectively connected with a lane change warning system, a lane change assistant system and an ACC system, the lane change assistant system is respectively bidirectionally connected with the lane change warning system and the ACC system, and the lane change assistant system is respectively connected with a lane change trajectory planning path tracker and an MPC controller. The invention not only has all the functions of the original ACC system, that ios, the rad traffic environment in front of the vehicle can be monitored by sensors such as a vehicle-mounted radar, and the vehicle can be longitudinally controlled so as to keep a safe distance between the vehicle and the front vehicle. It can also change lanes automatically when there is complicated traffic condition in front or the driver has the intention to change lanes to avoid obstacles. And the controller can effectively avoid accidents, but also greatly improve theACC system of driver lane change caused by discomfort.
