VEHICLE SUPPORT DEVICE FOR EXECUTING COLLISION PREVENTIVE OPERATIONS ON THE BASIS OF A POSITION AND A MOTION CONDITION OF A TARGET OBJECT

摘要

A driving support apparatus installed in a host vehicle calculates an overlap ratio concerning a target object located in front of the host vehicle within the same lane as the ratio of the width of the target object to its lateral distance from a lane marker line of the lane, and detects in addition, the moving condition of the object (that is, whether it is stationary, moving in the direction or the same direction as the host vehicle, or moving laterally with respect to the forward direction of the host vehicle). An amount of compensation for delaying or advancing the start of a collision avoiding operation by the driving support device is determined on the basis of the overlap ratio and / or the moving condition of the target object.
