Radar device for a vehicle
First Claim
1. A radar device for a vehicle, said radar device comprising:
- an image taking means for obtaining an image including a road surface in front of or behind said vehicle;
a sensor having a center axis for obtaining at least positional information on an object of detection in front of or behind said vehicle; and
a control means for correcting the direction of said center axis of said sensor based on said image obtained by said image taking means, said control means including;
a line segment detecting means for detecting on said image a line segment along a lane in which said vehicle is traveling;
a vector detecting means for detecting a vector indicative of the direction on a road-fixed coordinate system of said line segment obtained by said line segment detecting means; and
a correcting means for controlling correction of horizontal and vertical directions of said center axis so as to coincide with the direction of said vector detected by said vector detecting means.

Abstract
A radar device mounted to a vehicle includes a camera for obtaining images including the road surface in front of or behind the vehicle on which it is mounted, a sensor having for obtaining at least positional information on a target object of detection such as another vehicle in front or behind and a control unit for correcting the direction of the center axis of the sensor based on the image obtained by the camera. The control unit detects a line segment along a lane in which the vehicle is traveling, detects a vector indicative of the direction on a road-fixed coordinate system of the obtained line segment, and controls correction of horizontal and vertical directions of the center axis of the sensor so as to coincide with the direction of the detected vector.
