Object detecting system for vehicle
First Claim
1. An object detecting system for a vehicle, comprising:
- a radar which includes an electromagnetic wave transmitting means for transmitting an electromagnetic wave in a direction of movement of the vehicle, and a reflected wave receiving means for receiving a reflected wave from an object existing ahead of the vehicle in the direction of movement of the vehicle; and
a determining means for determining presence or absence of an obstacle in the direction of movement of the vehicle based on a result of detection by said radar,wherein said radar can detect objects in each of a plurality of vertically different detection areas, andwherein the detection areas are established so that an overlapped region, produced by overlapping of the detection areas, includes a region parallel to a travel road surface.

Abstract
An object detecting system for a vehicle includes a radar. The radar includes an electromagnetic wave transmitting device for transmitting an electromagnetic wave in a direction of movement of the vehicle and a reflected wave receiving device for receiving a reflected wave from an object which exists ahead of the vehicle in the direction of movement of the vehicle. A determining device determines the presence or absence of an obstacle in the direction of movement of the vehicle based on the result of the detection by the radar. In the object detecting system, the radar can detect objects in a plurality of vertically different detection areas, respectively. In addition, it is clear in which areas the object has been detected. Thus, it is possible to appropriately determine whether there is a possibility that the object is an obstacle to the vehicle.
