Method and apparatus for recognizing shape of road |
摘要 |
A transmission wave is applied to a predetermined angular range in a width-wise direction of a vehicle. A position of each object and a relative speed of the object are detected on the basis of the reflected wave. A determination is made as to whether each object is moving or stationary on the basis of the detected relative speed of the object and a speed of the vehicle. For at least one of right-hand and left-hand sides of the vehicle, calculation is given of a vehicle width-wise direction position where each stationary object effective for road shape recognition passes through the related side of the vehicle. The calculated vehicle width-wise direction position is memorized. A line connecting the memorized vehicle width-wise direction position and the detected position of the currently handled object corresponding to the effective stationary object is recognized as a road edge.
