OBJECT DETECTOR

摘要

An object detection circuit detects an object moving in a periphery of a vehicle by a frame correlation method that uses a plurality of shot images captured at successive times. A state judgment part disables a detection function of the object detection circuit when a steering angle of an own vehicle is not in a prescribed steering angle range. Then, a condition changer changes the prescribed steering angle range corresponding to a condition of the steering angle in accordance with a velocity of the own vehicle. Therefore, the condition changer can relax the condition for enabling the detection function in accordance with the velocity of the own vehicle within a range where detection accuracy is ensured.

1. An object detector comprising:
a detector that detects, by a frame correlation method that uses a plurality of shot images of a periphery of a vehicle captured by a camera at successive times, an object moving in the periphery of the vehicle; and a controller that (i) acquires information about a velocity of the vehicle and about a steering angle of the vehicle, (ii) disables a detection function of the detector when the acquired steering angle is not in a prescribed steering angle range, and (iii) changes the prescribed steering angle range in accordance with the acquired velocity of the vehicle.
