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 can be made to the route or vehicle speed to ensure safe execution of the lane change.

Furthermore, the patent also 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 during the maneuver. The system also considers factors such as the presence of a median strip between travel routes and the relative speeds and sizes of the vehicles involved. Additionally, a travel assistance device is described, equipped with sensors to detect the surrounding environment and facilitate safe lane changes based on the determined route and vehicle speed. Another aspect of the patent covers a similar travel assistance method for performing turns, taking into account the presence of oncoming vehicles and adjusting the route or speed accordingly to ensure safe navigation.
