Moving object detection apparatus and drive support apparatus
First Claim
1. A moving object detection apparatus that is provided on a host vehicle positioned adjacent a shield object, the shield object positioned behind the host vehicle and at a left side thereof or at a right side thereof, the vehicle including a radar sensor on a front or rear portion thereof and a drive support control apparatus configured to perform a drive support control for reducing a probability of a collision between the host vehicle and a monitoring object passing behind the host vehicle from the left side thereof to the right side thereof or from the right side thereof to the left side thereof,the moving object detection apparatus generating, based on detection information of the radar sensor, object information used in the drive support control, the moving object detection apparatus comprising circuitry configured to:
- calculate, based on detection information of an object from the radar sensor, a moving direction of the object with respect to the host vehicle to generate the object information, the object information including the information representing the calculated moving direction;
set an invalidation time period or an invalidation section according to a size of a shield range due to the shield object, the invalidation time period is set from a detection start timing when the object is started to be detected by the radar sensor, and the invalidation section is set from a position of the vehicle at the detection start timing such that the invalidation time period and the invalidation section becomes longer when a detection start distance is a first value than when the detection start distance is a second value that is smaller than a first value, the detection start distance corresponding to a distance between the host vehicle and the object at the detection start timing; and
prevent a calculation of the moving direction during a period from the detection start timing to an invalidation end timing, the invalidation end timing being at a lapse of the invalidation time period or a timing when the object exits from the invalidation section, or prevent the calculated moving direction from being used as the moving direction of the monitoring object in the drive support control during the period from the detection start timing to the invalidation end timing.

Abstract
A moving object detection apparatus is configured to calculate, based on detection information of an object from a radar sensor, a moving direction of the object with respect to a host vehicle to generate object information, the object information including information representing the calculated moving direction; set an invalidation time period or an invalidation section; and prevent a calculation of the moving direction during a period from the detection start timing to an invalidation end timing, the invalidation end timing being at a lapse of the invalidation time period or a timing when the object exists from the invalidation section, or prevent the moving direction calculated by the object information generating part from being used in a drive support control during the period from the detection start timing to the invalidation end timing.
