Road-shape recognition system
First Claim
1. A road-shape recognition apparatus comprising:
- a radar device for emitting a detection wave ahead of a vehicle, and detecting objects in response to echoes of the emitted detection wave;
reflector detecting means for detecting reflectors among the objects detected by the radar device, the reflectors being located along a road;
reflector-row extracting means for, in cases where there are a plurality of rows of the reflectors detected by the reflector detecting means in one side of the vehicle, extracting one from among the reflector rows; and
road-shape recognizing means for recognizing a shape of the road on the basis of the reflector row extracted by the reflector-row extracting means.

Abstract
A radar device operates for emitting a detection wave ahead of a vehicle, and detecting objects in response to echoes of the emitted detection wave. A reflector detecting device operates for detecting reflectors among the objects detected by the radar device. The detected reflectors are located along a road. A reflector-row extracting device operates for, in cases where there are a plurality of rows of the reflectors detected by the reflector detecting device in one side of the vehicle, extracting one from among the reflector rows. A road-shape recognizing device operates for recognizing a shape of the road on the basis of the reflector row extracted by the reflector-row extracting device.
