Definitions
- the present invention relates to the field of driving aids to driving a vehicle and to a secondary object located on the traffic lanes adjacent to said vehicle when changing lanes. a motor vehicle, including obstacle avoidance systems.
- the pre-collision time estimation module comprises a module for calculating an angle between the motor vehicle and the detected object, assuming that the trajectory of the object is parallel to the main track, a module projecting the relative velocities transmitted by the radar on the road axis to obtain a relative speed that follows the road in order to exploit these data whatever the speed of the road, and a module for calculating the time before collision for each object detected by the radar for each obj and detected according to the actual distance and the relative speed.
- the most critical detected object is determined by filtering the detected objects whose flag is true, that is, the objects in the danger zone, and determining the most critical of them. depending on the distance to the vehicle and / or the time before collision.
- FIG. 2 diagrammatically illustrates the danger zone determined by the collision risk detection system of FIG. 1;
- the collision risk detection system 10 comprises a data recovery module 12 from detection means (not shown) provided on the motor vehicle.
