摘要： A control system for an unattended transport car including a plurality of ground radio transmitters dispersed in a range within which the unattended transport car is movable, the transmitters transmitting positional information or the like by radio. The unattended transport car is provided with detecting means for detecting in a non-contact manner positional information concerning each of the ground radio transmitters memory means for storing a traveling course from a specific start point to a specific end point in the form of a series of pieces of positional information concerning the ground radio transmitters, and control means for effecting traveling course control and start-stop control every time the car passes one of the ground radio transmitters by constantly or intermittently comparing the positional information concerning each ground radio transmitter detected by the detecting means with the contents stored in the memory means. Thus, it is possible to realize traveling control of high reliability with a simplified control program. Further, the unattended transport car is able to determine whether to move forward or backward, turn right or left and stop or proceed.
