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.

First claim

The invention claimed is:

1. A vehicle position guidance system that guides a user to a position of a parked vehicle, the vehicle position guidance system comprising:
a terminal position measurement section that measures a position of a terminal carried by the user;
a vehicle position measurement section that measures the position of the parked vehicle;
a calculator that obtains a route for the user to reach the parked vehicle using position information related to the terminal measured by the terminal position measurement section and position information related to the parked vehicle measured by the vehicle position measurement section; and
a guide that 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 that has been obtained by the calculator, wherein
the first guidance provides guidance to the position of the parked vehicle using the terminal, and
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.

2. The vehicle position guidance system according to claim 1 , wherein, after the user gets out of the vehicle, the vehicle autonomously locates a parking position and automatically travels to the parking position to proceed with parking.

3. The vehicle position guidance system according to claim 1 , wherein the terminal position measurement section and the vehicle position measurement section measure their own positions using at least one of a network communication via a wireless LAN or a global positioning system that measures a position using radio waves from a satellite.

4. The vehicle position guidance system according to claim 1 , comprising an operating section that causes the parked vehicle to automatically travel to an entering position of the parked vehicle when the entering position is designated, wherein
the calculator obtains a route to the entering position designated by the user, and
the guide guides the user to the entering position in accordance with the route to the entering position.

5. The vehicle position guidance system according to claim 4 , wherein the operating section obtains an expected time at which the user will reach the entering position and causes the vehicle to automatically travel in accordance with the expected time.

6. The vehicle position guidance system according to claim 1 , wherein the first guidance is provided by at least one of a sound notification or a screen display in the terminal.

7. The vehicle position guidance system according to claim 1 , wherein the second guidance is provided through projection of an image using the vehicle on-board device.

8. The vehicle position guidance system according to claim 7 , wherein the guide checks whether near-field communication between the vehicle and the terminal is established and performs, when the near-field communication is established, the second guidance to execute guidance through the projection of the image using the vehicle on-board device.

9. The vehicle position guidance system according to claim 7 , wherein the projected image provided by the vehicle on-board device associates the terminal and the vehicle with each other.

10. The vehicle position guidance system according to claim 7 , comprising a registration section that manages registration of the projected image by the user.

11. A vehicle position guidance method that guides a user to a position of a parked vehicle, the vehicle position guidance method comprising:
measuring a position of a terminal carried by the user;
measuring the position of the parked vehicle;
obtaining a route for the user to reach the parked vehicle using measured position information related to the terminal and measured position information related to the parked vehicle; and
assisting 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 calculated route, wherein
the first guidance provides guidance to the position of the parked vehicle using the terminal, and
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.
