  • Patent number: 11680811
    Abstract: A vehicle position guidance system includes a terminal position measurement section, a vehicle position measurement section, a calculator, and a guide. The terminal position measurement section measures a position of a terminal carried by a user. The vehicle position measurement section measures a position of a parked vehicle. The calculator obtains a route using position information related to the terminal and position information related to the parked vehicle. The guide assists the user in entering the vehicle by selectively using a first guidance and a second guidance depending on whether a distance is long or short between the terminal and the parked vehicle on the route. The first guidance provides guidance to the position of the parked vehicle using the terminal. The second guidance provides guidance to the position of the parked vehicle through a notification using a vehicle on-board device of the parked vehicle.
