  • Publication number: 20190250614
    Abstract: A vehicle guidance system to guide a vehicle includes a vehicle, a positioning device to measure a location of the vehicle and output location information of the vehicle, and a guidance device to guide the vehicle. When the guidance device guides the vehicle from a first location, through a second location, to a third location, the guidance device transmits a first guidance command to guide the vehicle from the first location to the second location. While the vehicle is moving from the first location toward the second location in accordance with the first guidance command, the guidance device estimates an expected location of arrival of the vehicle based on a change in the location of the vehicle as measured by the positioning device. The guidance device generates a second guidance command to guide from the expected location of arrival to the third location, and before the vehicle arrives at the expected location of arrival, transmits the second guidance command to the vehicle at least once.
