Title: Object detector and traveling vehicle
Inventor: HIRABAYASHI KENICHI
IPC: G01S15/93
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To enhance detection accuracy of obstacle while reducing the width being occupied by an automatically guided vehicle during traveling by increasing the number of measurements for operating a mean value in a range approximately perpendicular to the radiating direction thereby making uniform the error width along a border lane in the direction perpendicular thereto. SOLUTION: The number of measurements for operating a mean value is increased as the angular range approaches just beside an automatically guided vehicle and the accuracy of mean value is enhanced. Error component in the direction perpendicular to the left and right border lines 37, 38 is decreased significantly in the range of the border lines 37, 38 just beside the vehicle. Width of a gray zone 41 in the direction perpendicular to the border lines 37, 38 is made uniform along the border lines 37, 38. Since the gray zone 41 is reduced just beside the vehicle, detection accuracy of obstacle is enhanced in the area 36 requiring measurement and the width being occupied by the vehicle can be reduced along the traveling route.
