Problems solved by technology
[0006] Aiming at the problem that the existing ACC system cannot handle complex traffic conditions such as intersections and vehicle merging, and the distance is fixed, the present invention needs to design a system that can not only change lanes autonomously when there is an emergency ahead, but also can change lanes when there are vehicles. Adaptive cruise controller with lane change assistance function switching to ACC system while driving and its working method

The invention discloses an adaptive cruise controller with a lane-changing auxiliary function and a working method thereof. The controller includes a sensing system, a lane-changing warning system, a lane-changing auxiliary system and an ACC system. The sensing systems respectively It is connected to the lane change warning system, the lane change assist system and the ACC system. The lane change assist system is bidirectionally connected to the lane change warning system and the ACC system respectively. The lane change assist system is respectively connected to the lane change trajectory planning path tracker. Connected to MPC controller. The invention not only has all the functions of the original ACC system, that is, it can monitor the road traffic environment in front of the car through sensors such as on-board radar, and control the vehicle longitudinally to keep the car at a safe distance from the car in front; it can also be used when there is complex traffic ahead. When the driver has the intention to change lanes, the system can avoid obstacles and change lanes autonomously; it can effectively avoid accidents and greatly improve the discomfort caused by the ACC system to the driver when changing lanes.
Description
technical field [0001] The invention relates to the technical field of assisted driving, in particular to an adaptive cruise controller with a lane-changing auxiliary function and a working method thereof. Background technique [0002] The development trend of the automobile industry is the "four modernizations of automobiles", namely electrification, intelligence, sharing and networking. On the basis of new energy vehicles, it combines intelligent bicycle technology and Internet technology to finally realize advanced assisted driving of intelligent network connection. Technology will become an inevitable trend in the future of the automotive industry. At the same time, in order to deal with the global safety problems 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 driving systems. At the same time, it ha...
