In order to give a warning to the driver of the host vehicle or to autonomously control the host vehicle in response to the output indicating the vehicle approaching suddenly from the rear or the output indicating the vehicle approaching extremely rapidly from the rear Lane assist system and method
A lane assistance system of a host vehicle for reacting to fast and extremely fast approaching vehicles includes a rear radar sensing unit having a sensor and an electronic controller. The electronic controller determines the distance and relative velocity of the fast approaching vehicle to the host vehicle. Further, depending on the closeness of the approaching vehicle, the lane of the approaching vehicle is determined from angular resolution of the radar signal. When the vehicle is approaching at an extremely fast rate and the angular resolution of the radar signal is not capable of determining an exact relative lane of the approaching vehicle due to the vehicle being too far away, the assistance system warns against or prevents lane changes by the host vehicle.
