10results about How to "Avoid driving" patented technology

This invention belongs to the field of assisted driving technology, specifically relating to a lane centering control method and system. The invention acquires the driving environment surrounding the vehicle's lane and determines whether there are obstacles in adjacent lanes based on the driving environment. When only one adjacent lane has an obstacle, if the distance D between the obstacle and the shared lane line satisfies 0 < D < H, the invention controls the vehicle to adjust laterally by a distance Δd from its current position to the side without obstacles. The value of Δd is calculated based on the distance D, the distance L between the vehicle and the other lane line, and a distance threshold H. This solves the problem of existing vehicle centering control methods failing to reasonably adjust the distance to obstacles when only one side of the vehicle has an obstacle, leading to low driving safety or comfort.
