Abstract:
The self-propelled vehicle system includes a drive line, a start marker, and a self-propelled vehicle. The self-propelled vehicle includes a plurality of drive line sensors arranged, in a direction intersecting with the travel direction of the self-propelled vehicle, at a wider range than a width of the drive line, a marker sensor that detects the start marker, and a control unit. After the start marker is detected by the marker sensor, the control unit nullifies the detection output of one group of the drive line sensors out of a plurality of groups that are formed by dividing all the drive line sensors, and in accordance with the detection output of another of the groups, the control unit makes the travel direction of the self-propelled vehicle follow the drive line branched towards a side of the another group, which is one of the two drive lines branched into two directions.

Claim (Index 13):
A drive control method of a self-propelled vehicle using:\n a drive line that is laid on a road surface and branches from a first direction into a second direction and a third direction; a start marker arranged along the drive line at an upstream side of a travel direction with respect to a point where the drive line branches into the second direction and the third direction; and a self-propelled vehicle that runs in the travel direction along the drive line and changes the travel direction, wherein the self-propelled vehicle includes:\n a drive section that runs the self-propelled vehicle; \n a plurality of drive line sensors that is arranged, in a direction intersecting with the travel direction of the self-propelled vehicle, at a wider range than a width of the drive line, and each detects the drive line; \n a marker sensor that detects the start marker; and \n a control unit that controls the drive section in accordance with a detection output of each of the drive line sensors and the marker sensor, \n the drive control method includes: a first step of causing the drive section to make the travel direction of the self-propelled vehicle follow the drive line of the first direction in accordance with the detection output of each of the drive line sensors before the start marker is detected by the marker sensor; and after the start marker is detected by the marker sensor, a second step of nullifying the detection output of the drive line sensors forming a group at one end side, the group being one of groups formed by dividing all the drive line sensors in the intersecting direction, and in accordance with the detection output of a group other than the group at the one end side, causing the drive section to make the travel direction of the self-propelled vehicle follow the drive line branched towards a side of the group other than the group at the one end side, the drive line to be followed being one of the two drive lines branched into the second direction and the third direction.
