Title:
STEERING CONTROLLER FOR FREE-RUNNING CAR
Document Type and Number:
Japanese Patent JPH043209
Kind Code:
A
Abstract:
PURPOSE:To facilitate the subsequent work restart in the case the work is interrupted in a state that the free-running car is inclined by constituting the controller so that in the case an incident light exceeding the scheduled number of times is detected from almost the same azimuth, the azimuth in which the incident light is detected is detected as an azimuth of a scheduled light reflecting means looked at from the free-running car. CONSTITUTION:In a photodetecting frequency discriminating part 32, the photodetecting frequency stored at every azimuth in a first azimuth storage part 31 is compared with the scheduled photodetecting frequency (threshold). As a result of comparison, the number of azimuths in which a photodetecting signal exceeding the threshold is detected is detected. When this number of azimuths coincides with the number of reflectors installed in advance, among the azimuths stored in a first azimuth storage part 31, the azimuth in which the photodetecting signal exceeding the threshold is detected is determined as the azimuth of the scheduled reflector. In such a way, even from a state that a free-running car is inclined, the reference point identification processing before running is executed by almost the same light beam scan as the time when running is being continued and the work can be started easily.
