Abstract
In order to use a manned-travel work vehicle, such as a multi-purpose transport vehicle, for transporting machinery or material or for moving for the purpose of work, a rest or the like, and to cause an unmanned-travel work vehicle to reliably arrive at a destination using wireless communication, the present invention provides a work vehicle transport system. In the transport system, travel trajectory information about a travel trajectory of a first vehicle that is a manned-travel work vehicle to a work location is transmitted via wireless communication to a second vehicle, and it is determined whether the second vehicle is to perform unmanned-travel along the travel trajectory.
Claims12
A system of movement control of work vehicles having a first vehicle which is a manned travel work vehicle and a second vehicle which is an unmanned travel work vehicle,
- characterized in that
- a wireless communication system which enables transmission of information between the first vehicle and the second vehicle is configured,
- the second vehicle receives travel trajectory information concerning a travel trajectory of the first vehicle and a state thereof by the wireless communication system, and performs unmanned operating travel to an objective position along the travel trajectory of the first vehicle based on the travel trajectory information, and
- whether the unmanned operating travel of the second vehicle is started or suspended is judged based on the travel trajectory information, and when suspended, travel suspension information which is information concerning a cause of travel suspension is transmitted to the first vehicle by the wireless communication system.
A system of movement control of work vehicles having a first vehicle which is a manned travel work vehicle and a second vehicle which is an unmanned travel work vehicle,
- characterized in that
- a wireless communication system which enables transmission of information between the first vehicle and the second vehicle is configured, and
- the second vehicle receives first travel trajectory information concerning a first travel trajectory of the first vehicle and a state thereof by the wireless communication system and performs unmanned operating travel along the first travel trajectory based on the first travel trajectory information, and receives second travel trajectory information concerning a second travel trajectory of the second vehicle and a state thereof and performs unmanned operating travel reversely along the second travel trajectory based on the second travel trajectory information.
A work system using a first vehicle which is a manned travel work vehicle and a second vehicle which is an unmanned travel work vehicle,
- characterized in that
- a wireless communication system which enables transmission of information between the first vehicle and the second vehicle is configured, and
- the second vehicle receives travel trajectory information concerning a travel trajectory of the first vehicle by the wireless communication system, the travel trajectory of the first vehicle demarcates a boundary of a work area based on the travel trajectory information, a work travel route of the second vehicle in the work area is calculated, and work travel can be performed unmannedly along the calculated work travel route.
