Travel assistance method for lane change in host vehicle
A recently granted patent (Publication Number: US11884276B2) discloses a travel assistance method for facilitating lane changes of a host vehicle based on a determined route and vehicle speed. The method involves detecting oncoming vehicles in the opposite lane when the host vehicle initiates a lane change. By determining a crossing point between the host vehicle's virtual advancing route and the linear advancing route of the oncoming vehicle, the system can decide whether to proceed with the lane change based on the time difference between when each vehicle is predicted to reach the crossing point. If the time difference falls within a predetermined range, adjustments are made to the route or vehicle speed to ensure safety during the lane change.
Furthermore, the patent includes provisions for decelerating or accelerating before the lane change based on the time difference between the vehicles, as well as changing the determined route to optimize the steering angle or start position of the lane change. The method also considers factors such as the speed of the oncoming vehicle, road width, and presence of a median strip to determine the crossing region and ensure safe execution of the lane change. Additionally, a travel assistance device is described in the patent, equipped with sensors to detect the surrounding environment and facilitate the lane change process by adjusting the route and speed of the host vehicle accordingly. Another aspect of the patent covers a similar travel assistance method for performing turns, taking into account the presence of oncoming vehicles and ensuring safe navigation onto a travel lane from a side road.
