The method for avoiding collision between a motor vehicle and obstacles placed in the path of the vehicle comprises the stages of forming a radar map of the area in front of the vehicle, reconstructing the geometry of the road, identifying its edges, detecting the position and speed of the vehicle with respect to the road, determining the presumed path of the vehicle on the basis of the road geometry and the manoeuvre being carried out by the vehicle at that instant, detecting objects on the radar map found lying in the presumed path of the motor vehicle and displaying the map found in a perspective representation, ignoring objects which are off the road and indicating objects in the path of the vehicle in a different manner according to their hazard and if appropriate generating alarms of an acoustic type.
In a method for avoiding collision between a human driven motor vehicle and at least one obstacle comprising the stages of:
In a system for avoiding collision between a human driven motor vehicle and at least one object, the system including a sensor (22) for monitoring an environment in front of the motor vehicle (100) to detect the presence of the object, means (47, 49) for calculating the distance (d.sub.obst) and the relative speed (V.sub.obst) of the object, and means (32, 34) for indicating the presence of the object with an indication of its hazard level, the improvement in that the sensor (22) is a scanning sensor for generating a map (115) of the environment in front of the motor vehicle (100) comprising means (39) for reconstructing the geometry of a road (116) on the basis of the map, means (15) for reconstructing a presumed path (119) for the motor vehicle on the basis of the reconstructed geometry of the road, and means (46) for searching for the object within the presumed path.
