VEHICULAR DRIVING SYSTEM AND DRIVING METHOD THEREOF
First Claim
1. A vehicular driving system for creating a driving path for vehicles along which a vehicle is to drive from an entry point of a loading site to a loading point where a loader exists, and for making the vehicle drive along the created driving path, characterized in thatthe system comprises:
- driving path creating means for creating a driving path from an entry point to a loading point by way of a waiting point located in a neighborhood of the loading point based on position information on the loading point and position information on the entry point;
first driving control means for making the vehicle drive from the entry point to the waiting point along the driving path created by the driving path creating means based on information on the driving path;
waiting means for making the vehicle stand by at the waiting point until a permission is given by the loader;
partial driving path creating means for creating, when there is an order to change the position of the loading point from the loader to a supervising device and/or to the vehicle while the vehicle is standing by at the waiting point or driving between the entry point and the waiting point, a partial driving path from the waiting point to the position changed loading point based on position information on the position changed loading point and position information on the waiting point on the driving path before the loading point has moved; and
second driving control means for making, when there is not the order to change the position of the loading point from the loader to the supervising device and/or to the vehicle while the vehicle is standing by at the waiting point and driving between the entry point and the waiting point, the vehicle drive from the waiting point to the loading point along the driving path created by the driving path creating means based on the information on the driving path, andfor making, when there is the order to change the position of the loading point while the vehicle is standing by at the waiting point or driving between the entry point and the waiting point, the vehicle drive from the waiting point to the position changed loading point along the partial driving path created by the partial driving path creating means based on the information on the partial driving path.

Abstract
Provided are a vehicular driving system and a driving method thereof that can improve production efficiency by driving a vehicle toward a loading point without fail even when the loading point is changed successively due to a movement or the like of a loader, and by keeping driving the vehicle as close as possible to the loader without stopping the vehicle forcedly (without waiting time). A waiting point, which is a point where the vehicle should stand by until permission is given by the loader to the vehicle, is set on a driving path. For example, a switch-back point is set as the waiting point. The vehicle drives from an entry point of a loading site to the waiting point along the driving path, and stands by at the waiting point until the permission is given by the loader. In a case when there is an order to change the loading point when the vehicle is standing by at the waiting point or driving from the entry point to the waiting point, a partial driving path is created, and the vehicle drives from the waiting point to the new loading point along the partial driving path. Meanwhile, in a case when there is no order to change the loading point when the vehicle is standing by at the waiting point and driving from the entry point to the waiting point, the vehicle drives from the waiting point to the original loading point along the driving path.

the system comprises: -
driving path creating means for creating a driving path from an entry point to a loading point by way of a waiting point located in a neighborhood of the loading point based on position information on the loading point and position information on the entry point; first driving control means for making the vehicle drive from the entry point to the waiting point along the driving path created by the driving path creating means based on information on the driving path; waiting means for making the vehicle stand by at the waiting point until a permission is given by the loader; partial driving path creating means for creating, when there is an order to change the position of the loading point from the loader to a supervising device and/or to the vehicle while the vehicle is standing by at the waiting point or driving between the entry point and the waiting point, a partial driving path from the waiting point to the position changed loading point based on position information on the position changed loading point and position information on the waiting point on the driving path before the loading point has moved; and second driving control means for making, when there is not the order to change the position of the loading point from the loader to the supervising device and/or to the vehicle while the vehicle is standing by at the waiting point and driving between the entry point and the waiting point, the vehicle drive from the waiting point to the loading point along the driving path created by the driving path creating means based on the information on the driving path, and for making, when there is the order to change the position of the loading point while the vehicle is standing by at the waiting point or driving between the entry point and the waiting point, the vehicle drive from the waiting point to the position changed loading point along the partial driving path created by the partial driving path creating means based on the information on the partial driving path. - View Dependent Claims (2, 3, 6)

4. A vehicular driving method for creating a driving path for vehicles along which a vehicle is to drive from an entry point of a loading site to a loading point where a loader exists, and for making the vehicle drive along the created driving path, characterized by
creating a driving path from the entry point to the loading point by way of a waiting point located in a neighborhood of the loading point based on position information on the loading point and position information on the entry point; -
making the vehicle drive from the entry point to the waiting point along the driving path based on information on the created driving path; making the vehicle stand by at the waiting point until a permission is given by the loader; creating, when there is an order to change the position of the loading point from the loader to a supervising device and/or to the vehicle while the vehicle is standing by at the waiting point or driving between the entry point and the waiting point, a partial driving path from the waiting point to the position changed loading point based on position information on the position changed loading point and position information on the waiting point on the driving path before the loading point has moved; and making, when there is not the order to change the position of the loading point from the loader to the supervising device and/or to the vehicle while the vehicle is standing by at the waiting point and driving between the entry point and the waiting point, the vehicle drive from the waiting point to the loading point along the driving path created by the driving path creating means based on the information on the driving path, and making, when there is the order to change the position of the loading point while the vehicle is standing by at the waiting point or driving between the entry point and the waiting point, the vehicle drive from the waiting point to the position changed loading point along the partial driving path created by the partial driving path creating means based on information on the partial driving path. - View Dependent Claims (5)
