METHOD AND DEVICE FOR ASSISTING IN THE AUTOMATED DRIVING OF A VEHICLE IN THE EVENT OF THE TRAFFIC LANE BEING SUBDIVIDED INTO PARTS OR PARTS THEREOF MERGING

摘要

A method is intended to assist the driver of a vehicle (VA) possibly being driven in an automated manner on a traffic lane (VC) defined by first (d1) and second (d2) boundaries. This method comprises a step in which, in the event of detection of an upcoming subdivision of the traffic lane (VC) into at least two parts (P1-P2), the vehicle (VA) is driven in an automated manner in an absolute mode, which involves making it follow a path situated at a chosen distance (de) from one of the first (d1) and second (d2) boundaries, and then, when the vehicle (VA) is situated on one of the parts (P1-P2), it is driven in an automated manner in a relative mode, which involves making it follow a path, relative to the width of the traffic lane, with respect to a median line (Im) situated at an equal distance from the first (d1) and second (d2) boundaries.
