Abstract:
1. A traveling vehicle system comprising: a plurality of traveling vehicles; a controller which controls operations of the plurality of traveling vehicles; and a power line which electrically connects the plurality of traveling vehicles with each other, and supplies electric power to each of the plurality of traveling vehicles; wherein each of the plurality of traveling vehicles (i) includes a motor which runs on the electric power supplied via said power line and drives the respective traveling vehicle, and (ii) when decelerating, generates regenerative electric power to be supplied to another one of the plurality of traveling vehicles via said power line; said controller controls the operations of the plurality of traveling vehicles so that a time when one or more first traveling vehicles of the plurality of traveling vehicles decelerates overlaps a time when one or more second traveling vehicles of the plurality of traveling vehicles accelerates, said first traveling vehicles being decelerating traveling vehicles, and said second traveling vehicles being accelerating traveling vehicles; and when the number of said first traveling vehicles is greater than the number of said second traveling vehicles, said controller controls the operations of the plurality of traveling vehicles so that a time of said first traveling vehicles decelerating overlaps a time of said second traveling vehicles accelerating.
