Object determination apparatus and collision avoidance assistance apparatus
First Claim
1. An object determination apparatus comprising:
- a sensing device that is mounted in a host vehicle, and that sends detection wave and receives the detection wave reflected from an object, and that detects the object in accordance with the received detection wave;
a detection unit that detects reflection intensity of the detection wave received by the sensing device, the reflection intensity changing in accordance with distance to the object; and
a determination unit that determines a state of the reflection intensity by comparing a peak of the reflection intensity with a predetermined threshold value and determines whether the object is a vehicle other than the host vehicle based on the state of the reflection intensity and lateral position information of the host vehicle obtained from the reflection intensity,wherein the predetermined threshold value is set to discriminate a vehicle-type object from an on-road structure-type object.

Abstract
An object determination apparatus includes: a sensing device that is mounted in a host vehicle, and that sends detection wave and receives the detection wave reflected from an object, and that detects the object; a detection unit that detects the state of reflection intensity of the detection wave received by the sensing device which changes with the distance to the object; and a determination unit that determines that the object is a vehicle other than the host vehicle when a peak of the reflection intensity exceeds a predetermined threshold value. Peaks of the reflection intensity change in accordance the distance to the object, but the peaks regarding vehicles tend to be higher than the peaks regarding on-road structures. Hence, by comparing a peak of the reflection intensity with the predetermined threshold value, it can be determined whether the detected object is a vehicle other than the host vehicle.
