Patent number: 10349572Abstract: 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.Type: GrantFiled: November 12, 2015Date of Patent: July 16, 2019Assignee: YANMAR CO., LTD.Inventors: Masaaki Yamashita, Tsuyoshi Kawakami, Daisuke Hirata
