Object detecting system for vehicle
First Claim
1. An object detecting system for a vehicle, comprising:
- an object detector which is mounted on a vehicle and detects an object existing ahead in an own vehicle traveling direction;
a detection state determinator which determines whether or not the object is detected by the object detector;
a clocking device which measures a time during which it is determined that the object is not detected by the detection state determinator;
a non-detection determinator which determines whether or not the time measured by the clocking device becomes a determination threshold value or more; and
an informing device which informs an occupant that the object is not detected for a predetermined time or more, based on a determination result of the non-detection determinator;
wherein the non-detection determinator includes a plurality of determination threshold values, and the informing device changes an information content in accordance with the determination threshold value which is used in determination.

Abstract
Whether or not a radar device detects an object is determined by a detection state determinator. Whether or not a time during which the object is not detected and which is measured by a clocking device becomes a determination threshold value or more, is determined by a non-detection determinator. Based on the determination results, an informing device informs an occupant that the object is not detected for a predetermined time or more. Therefore, a state in which the radar device does not detect an object due to absence of the object on a road in a desert or the like is prevented from being erroneously determined as a state caused by contamination of the radar device. Also, the occupant can easily determine whether the operation of the informing device is actually caused by absence of an object or contamination of the radar device, based on the environment around the road on which the own vehicle is traveling. Especially because a reflected wave from a road surface, of which intensity changes in accordance with the condition, is not used for determination, it becomes unnecessary to change the setting of the determination threshold value and determination frequency region, and thus the structure and operation are simplified.
