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.

Description

technical field [0001] The invention relates to the technical field of driving assistance, in particular to an adaptive cruise controller with a lane-changing assistance function and a working method thereof. Background technique [0002] The development trend of the automobile industry is "four modernizations of automobiles", that is, electrification, intelligence, sharing, and networking. On the basis of new energy vehicles, combined with single-vehicle smart technology and Internet technology, the advanced assisted driving of intelligent networking is finally realized. Technology will become an inevitable trend in the future of the automotive industry. At the same time, in response to global safety issues caused by traffic accidents, advanced driver assistance systems have been developed rapidly. Adaptive cruise control (ACC: Adaptive Cruise Control) and lane change assistance systems are important components of advanced driver systems. How to integrate them At the same ...
