Abstract

There is provided an alternative vehicle guiding system wherein a communication sever system receives a fault condition information from vehicles and also transmits the necessary information to the navigation system of an alternative vehicle in order to prevent the damage of loads by quickly guiding the alternative vehicle to the fault generating vehicle position and then realizing smooth transfer of remaining work to the alternative vehicle.

The navigation system, fault monitoring means and vehicle communication means are respectively provided in the vehicles for transportation work and the center server system is also provided to transmit the vehicle distribution information to the vehicles. When a fault is generated in the vehicle, the communication server system receives the information from this vehicle and the navigation system of the alternative vehicle displays the transmitted information. Thereby, the alternative vehicle can always be distributed smoothly without any manual operation, the time required until the alternative vehicle arrives and the work transfer time can be shortened and adverse effect on the loads and successive load distribution work can be prevented.

Claims

2. A communication server system to issue the work instructions by transmitting the information of relaying point and destination for transportation work to the vehicle communication means of each vehicle through the radio communication link among a plurality of vehicles for transportation work based on the preset vehicle distribution information, wherein the position information of relaying point and destination for transportation work based on the vehicle distribution information is transmitted as the initial value to a plurality of vehicles, thereafter the information acquired in the vehicle side including the fault condition information from a certain vehicle is suddenly received, if it is determined that said vehicle cannot eliminate the fault condition, the relevant fault generating vehicle position and the relaying point and destination at which the fault generating vehicle does not yet arrive assigned to the fault generating vehicle are additionally assigned as the relaying point and/or destination of the other predetermined vehicle and the added position information of relaying point and/or destination is transmitted to the vehicle communication means of said predetermined vehicle via the radio communication link.

3-1. An alternative vehicle guiding system as claimed in claim 3, wherein said communication server system searches, a fault condition information is suddenly received from a certain vehicle and a vehicle is requested in place of a fault generating vehicle, the route passing the fault generating vehicle position and the not-passing relaying point and destination assigned to the fault generating vehicle from the current positions of vehicles other than said fault generating vehicle and issues instruction to the predetermined vehicle among a plurality of vehicles which realizes the optimum route to add said fault generating vehicle position and the not-passing relaying point and destination assigned to the fault generating vehicle as the new relaying point and/or destination of said predetermined vehicle.

4. An alternative vehicle guiding system as claimed in claim 4, wherein the optimum route is obtained for the predetermined vehicle which can realize said optimum route by specifying said fault generating vehicle position and the not-passing relaying and destination assigned to the fault generating vehicle as the new points for vehicle to pass in addition to the not-passing relaying point and destination assigned to said vehicle and the information of said optimum route is notified to said predetermined vehicle.

5. An alternative vehicle guiding system as claimed in claim 4, wherein said communication server system searches the route passing the said fault generating vehicle position and not-passing relaying point and destination assigned to said fault generating vehicle from the current positions of vehicles other than said fault generating vehicle and determines whether a plurality of vehicles satisfy or not one or a plurality of restriction conditions in relation to the work assigned to said fault generating vehicle and also issues an instruction to the predetermined vehicle among a plurality of vehicles that satisfies said conditions for work and can realize the optimum route to add said fault generating vehicle position and not-passing relaying point and destination assigned to the fault generating vehicle as the new relaying point and/or destination.
