A system and method for detecting the risk of collision between a vehicle and a secondary object located in a lane adjacent to the vehicle when changing lanes

摘要

The present invention relates to a method for detecting a risk of collision between a vehicle and a secondary object located in lanes adjacent to a main lane of the vehicle in case of a lane change by the vehicle. Detecting the presence and estimating a time-to-collision (TTC) between the vehicle and the detected object. The step of detecting the presence of objects in the danger zone (Z) includes: each detected by the radar due to the conversion of the distance (X) transmitted by the radar corresponding to the linear distance between each object detected by the radar and the vehicle. Calculating an actual distance (L _AB ) between the object of the vehicle and the vehicle, wherein the actual distance (L _AB ) corresponds to the length of an arc between two points; Determining a danger zone Z as a function of the lines of the main lane and the width of the main lane; And for each object detected by the radar, checking whether the coordinates L _AB , Y of the object are within a predetermined danger zone Z.
