20120296495 | VEHICULAR DRIVING SYSTEM AND DRIVING METHOD THEREOF - 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. | 11-22-2012 |
20120330540 | APPARATUS AND METHOD FOR CONTROLLING TRAVEL OF VEHICLES - A method for causing vehicles to travel improves work efficiency by minimizing stop time of the vehicles while avoiding deadlock, wherein reservation-requested routes are generated for the respective vehicles. The reservation-requested routes are parts of travel routes and between the current positions and travel stop positions, and are generated in so that a position not interfering with an interference region shown on a map and the terminal position of the reservation-requested routes for other vehicles becomes a terminal. Then, an already reserved route, is generated on conditions that the reservation-requested route for the vehicle does not interfere with the already reserved routes for the other vehicles and that deadlock does not occur. Then, the respective vehicles are controlled to travel from the current positions to the terminal positions of the already reserved routes. | 12-27-2012 |
20130211712 | DRIVE SYSTEM FOR UNMANNED VEHICLE AND METHOD OF DRIVE CONTROL OF THE SAME - In giving a travel command to an unmanned vehicle in both-side loading, or in setting a position of a loading point in both-side loading, whether a working machine of a loading machine is positioned on left-loading point side or right-loading point side is discriminated in correlation between an orientation or a position of the working machine when the travel command is instructed and a direction or a position of the boundary line. In setting the position of the loading point in both-side loading, whether the working machine of the loading machine is positioned on left-loading point side or right-loading point side is discriminated in correlation between the orientation or the position of the working machine when position setting of loading point is instructed and the direction or the position of the boundary line. | 08-15-2013 |
20130238182 | METHOD OF CONTROLLING TRAVEL WITHIN TRAVEL SYSTEM FOR UNMANNED VEHICLE AND TRAVEL SYSTEM FOR UNMANNED VEHICLE - Topographical data for a work location is created and information on a new travel route is generated. Next, a work location including the new travel route is constructed on the basis of the created topographical data. Then, the information on the new travel route generated is provided to the vehicle, the vehicle is made to travel along said new travel route in accordance with temporary travel control data, and actual topographical data for the new travel route is acquired. Next, the aforementioned temporary travel control data is corrected on the basis of the acquired actual topographical data for the new travel route. After that, the unmanned vehicle is made to travel in accordance with the corrected travel control data. | 09-12-2013 |
20130325208 | DRIVING SYSTEM OF UNMANNED VEHICLE AND DRIVING PATH GENERATION METHOD - Based on initial position information on an instructed fixed switch-back point and position information on a loading point, a relative positional relationship between the loading point and the switch-back point is generated. If the position of the loading point moves, then based on position information on the position- moved loading point, information on a direction of an unmanned vehicle at the loading point and information on a relative positional relationship, a new switch-back point is set at a position where the relative positional relationship can be maintained. When the initial position of the switch-back point is instructed, then on the basis of the initial position information on the switch-back point, a driving path leading to the loading point via the instructed switch-back point is generated and, when the position of the loading point moves, a driving path leading to the position-moved loading point via the new switch-back point is generated. | 12-05-2013 |
