A control device for guided travel of an unmanned vehicle, in which the unmanned vehicle is guided to travel by receiving a signal sent from a GPS satellite by the unmanned vehicle, measuring its own vehicle position based on the signal, and controlling such that a positional shift between the vehicle position and a target point that is a passing point sequentially set on a target traveling course falls into an allowable range for controlling error, wherein a guidable range is set in advance such that a position measurement error is added to the allowable range for controlling error; the position measurement error is obtained based on position measurement accuracy information from the signal; the allowable range for controlling error is changed according to the obtained position measurement error; and control is performed such that the positional shift falls into the changed allowable range for controlling error.

Leveling operation can be effectively performed at a discharge site without increasing a cost of vehicles, and a running course can be easily generated in a short time and at a low-cost. Based on each of measured position data of a survey lineof a discharge site, a normal line Lc normal to the survey lineis obtained, a target discharge position' is positioned at a prescribed distance away from the survey linein an inward direction of the discharge sitebased on the normal line Lc, and then data of a running coursein which a reference approach directionto approach the target discharge position&#x2032; is a direction normal to the survey lineare generated.

A restricted area () is created based on positional information of a manned vehicle () traveling one of outward/return lanes (), and a detour course () is created based on information of the restricted area (). Information on the detour course () is provided to the unmanned vehicles () and the manned vehicle (). Based on the positional information of the unmanned vehicles () which proceed towards each other from the opposite directions with the restricted area () therebetween, the unmanned vehicle () on the lane () which is the opposite side of the restricted area () is blocked at a block position (B) and at the same time a travel permission command for permitting traveling the detour course () is issued to the unmanned vehicle () traveling the lane () on the restricted area side so that the unmanned vehicle () travels the detour course ().

Travel control device and method for vehicles

A travel controlling apparatus of an unmanned vehicle provided with a GPS receiver ( ) receiving a GPS signal so as to position a position of a vehicle, an autonomous navigation computing device ( ) positioning a position and an azimuth of the vehicle on the basis of a traveling direction and distance of the vehicle, a position measuring portion ( ) calculating a present position and azimuth, and a travel controlling portion ( ) controlling the vehicle travel. The travel controlling apparatus is provided with a roadside zone distance measuring device ( ) for measuring a distance from the vehicle to a roadside zone ( ) provided in a side of the traveling path ( ), and the present position and azimuth is determined on the basis of the roadside zone distance measured by the roadside zone distance measuring device ( ).

Travel controlling apparatus of unmanned vehicle

What is proposed is a battery pack incorporating a lithium ion battery. The battery pack has: a circuit board (,A) of the type that parts are mounted on one surface thereof, on the part-mounting surface (,A) of which a plurality of circuit parts (,) forming a protective circuit (,) for preventing the over-charge and over-discharge of the battery; and resin (,A) which seals the whole part-mounting surface of the circuit board after the circuit parts have been mounted thereon. Transistors (Q,and Q,) and ICs (IC,and IC,) employed as the circuit parts are bear chips.
