Riderless vehicle steering control apparatus |
摘要 |
A vehicle steering control apparatus for following a riderless vehicle over a reference path defined by a guide tape installed on a floor. A sensor assembly, mounted on the vehicle bottom surface, includes a plurality of sensor units arranged on a line. Each the sensor unit includes a downward-facing light emission diode operable to emit a light ray and a downward-facing photodiode sensitive to a light ray received thereon for generating a sensor signal corresponding to the sensed light intensity. The sensor signal from each the sensor unit is applied to a control circuit which provides a command signal corresponding to the received sensor signals. The riderless vehicle includes a steering device responsive to the command signal for correcting vehicle steering to aline the vehicle sufficient well over the reference path. The control apparatus includes a drive circuit for driving the sensor units in a time-sharing fashion causing sequential light emission of the light emission diodes in a predetermined sequence.
