发明名称 HAULAGE VEHICLE AND TRAVEL CONTROL SYSTEM FOR THE SAME
摘要 A haulage vehicle comprises: a position calculating system (220) calculating an estimated position of its own vehicle; a position range calculating unit (201b) calculating a position range which is centered around the estimated position and in which the haulage vehicle is present with a predetermined expected probability; a maximum deviation amount calculating unit (602) calculating a maximum deviation amount indicating a highest value among the amounts of deviations between a target route of the haulage vehicle and each of points included in the position range; a target vehicle-speed decision unit (603) setting a target vehicle speed of the haulage vehicle to be relatively low when the maximum deviation amount is relatively large; and a target route-tracing unit (201g) performing control for the haulage vehicle to travel along the target route in compliance with the target vehicle speed.

主权项 1. A haulage vehicle connected to a control server configured to implement fleet management over wireless lines and to autonomously travel while taking instructions from the control server into account, comprising: a position calculating device configured to calculate an estimated position of its own vehicle; a position range calculating unit configured to calculate a position range which is centered around the estimated position and in which the haulage vehicle is present with a predetermined expected probability; a maximum deviation amount calculating unit configured to calculate a maximum deviation amount indicating a highest value among the amounts of deviations between a target route of the haulage vehicle and each of points included in the position range; a target vehicle-speed decision unit configured to set a target vehicle speed of the haulage vehicle to be relatively low when the maximum deviation amount is relatively large; and a target route-tracing unit configured to perform control for the haulage vehicle to travel along the target route in compliance with the target vehicle speed.
