VEHICLE DRIVING SUPPORT APPARATUS FOR EXECUTING COLLISION AVOIDANCE OPERATIONS BASED ON POSITION AND MOTION CONDITION OF TARGET OBJECT
First Claim
1. A driving support apparatus for installation in a host vehicle, the host vehicle incorporating a target object information detection apparatus for detecting target objects positioned ahead of the host vehicle and a lane marker line detection apparatus for detecting a pair of lane marker lines delimiting a traffic lane of the host vehicle, the driving support apparatus comprising:
- target object information acquisition means configured for acquiring target object information relating to a target object, based on detection results produced from the target object detection apparatus;
lane marker line information acquiring means configured for acquiring lane marker line information relating to the pair of lane marker lines, based on detection results produced from the lane marker line detection apparatus;
ratio calculation means configured for calculating at least one overlap ratio based on the lane marker line information and on the target object information, as a ratio of a value of lateral distance to a value of width of the target object, respectively as measured in a direction at right angles to a forward direction of the host vehicle and respectively as viewed from the host vehicle, the lateral distance comprising a distance between the target object and one of the pair of lane marker lines;
motion condition detection means configured for detecting a motion condition of the target object, based upon the target object information; and
, timing compensation means configured for setting a compensation amount of advancement or retardation to be applied to a timing of commencement of a driving support operation, the driving support operation to be potentially executed for avoiding collision between the target object and the host vehicle, and thecompensation amount being based upon the overlap ratio calculated by the ratio calculation means and the motion condition detected by the motion condition detection means.

Abstract
A driving support apparatus installed in a host vehicle calculates an overlap ratio relating to a target object positioned ahead of the host vehicle within the same traffic lane, as the ratio of the width of the target object to its lateral distance from a lane marker line of the traffic lane, and also detects the motion condition of the object (i.e., stationary, moving towards, or in 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 retarding or advancing the commencement of a collision avoidance operation by the driving support apparatus is determined based on the overlap ratio and/or the motion condition of the target object.
