Abstract (en)
[origin: WO2019154549A1] The invention relates to a method for detecting a risk of collision between a motor vehicle and a secondary object located in traffic lanes adjacent to the main traffic lane of said motor vehicle, in the event of a lane change by said vehicle, which involves detecting the presence of objects in a predetermined danger zone (Z), and estimating a time-to-collision (TTC) between the vehicle and a detected object. Detecting the presence of objects in a danger zone (Z) involves: calculating the actual distance (LAB) between the motor vehicle and each object detected by the radar resulting from a transformation of the distance (X) transmitted by the radar corresponding to the distance in a straight line between the motor vehicle and each object detected by the radar, the actual distance (LAB) corresponding to the length of an arc between two points; determining a danger zone (Z) as a function of the lines of the main traffic lane and the width of the main traffic line; and checking, for each object detected by the radar, whether its coordinates (LAB, Y) are inside the predetermined danger zone (Z).
