DEVICE AND METHOD OF CONTROLLING ATTITUDE OF UNMANNED CONVEYING VEHICLE FOR LATERAL MOVEMENT THEREOF

摘要

A device for controlling the attitude of an unmanned conveying vehicle (1) for lateral movement thereof, the device having a lateral-movement mode in which a driving unit (11-1) mounted at the front of a vehicle body (10) and a driving unit (11-2) mounted at the rear of the vehicle body move on different tracks (20-1, 20-2), wherein the device has a lateral-movement condition estimating means (S2) for estimating lateral-movement conditions of the vehicle body (10) based on a time difference occurring between the times at which the front driving unit (11-1) and the rear driving unit (11-2) pass through check points (21-1, 21-2) which are arranged on the tracks (20-1, 20-2) so that the front driving unit (11-1) and the rear driving unit (11-2) pass through the check points (21-1, 21-2) at the same time if the vehicle body (10) has a correct attitude. The device is not complex in structure and can be produced at low costs.
