METHOD AND SYSTEM FOR MANAGING A LANE CHANGE OF AN AUTONOMOUS OR PARTIALLY AUTONOMOUS VEHICLE

摘要

The invention relates to a method for managing a lane change of a vehicle, hereafter called host vehicle (1), equipped with an automated driving system (2), the method comprising the following steps: - determining whether the distance between a first vehicle, or front vehicle (6), travelling on an adjacent lane, called target lane (3), and a second vehicle, or rear vehicle (7), travelling on the target lane, is sufficient to allow the host vehicle (1) to enter under nominal conditions; - proceeding with changing the lane of the host vehicle (1) to the target lane if the distance between the front vehicle (6) and the rear vehicle (7) is not sufficient to allow the host vehicle (1) to enter the lane under nominal conditions, and if the risk of collision with the rear vehicle (7) is estimated to be considerably higher than the risk of collision with the front vehicle (6), by provisionally lowering the setpoint value of the minimum safety distance with respect to the front vehicle (6) from a nominal value to a low value; - progressively increasing the setpoint value from the minimum safety distance with respect to the front vehicle (6) to its nominal value when the host vehicle (1) is on the target lane and has entered between the front vehicle (6) and the rear vehicle (7).
