Abstract

The on-board apparatus 50 calculates an automated driving route of the vehicle 55 from the parking space of the vehicle 55 to the destination and an estimated time required to reach the destination in the case in which the vehicle 55 drives by automated driving by following the automated driving route. The server apparatus 30 calculates a walking travel route in the case of traveling by walk from the position of the terminal apparatus 10 to the parking space of the vehicle 55 and an estimated time required to reach the parking space of the vehicle 55 in the case of walking by following the walking travel route. The terminal apparatus 10 displays at the display unit 140 the automated driving route, the estimated time required for the automated driving route, the walking travel route, and the estimated time required for the walking travel route; and when a selection of the automated driving route is accepted, the terminal apparatus 10 starts the drive of the autonomous vehicle.

First claim

The invention claimed is:

1. A method for selecting a route, comprising:
an operation to start exiting from a parking acceptance step of operating an autonomous vehicle to start exiting from a parking space via a terminal apparatus owned by a user;
a parking position information obtaining step of obtaining information indicating a location of the parking space from an on-board apparatus of the autonomous vehicle when accepting the operation to start exiting from a parking as a trigger;
a terminal position information obtaining step of obtaining terminal position information indicating a present location of the terminal apparatus;
a first search step of searching an automated driving route of an autonomous vehicle, the automated driving route being from the parking space of the autonomous vehicle to the present location of the terminal apparatus;
a first calculation step of calculating a first estimated time to reach the present location of the terminal apparatus in a case in which the autonomous vehicle drives by following the automated driving route;
a second search step of searching a walking travel route in a case of traveling by walk from the present location of the terminal apparatus to the parking space;
a second calculation step of calculating a second estimated time to reach the parking space of the autonomous vehicle in a case of walking by following the walking travel route;
a display step of displaying at a display the automated driving route and the first estimated time, and the walking travel route and the second estimated time, and presenting both of the first estimated time and the second estimated time to the user;
an acceptance step of accepting a selection of either the automated driving route or the walking travel route by operating the terminal apparatus of the user; and
an instruction step of instructing the autonomous vehicle to start driving by automated driving when the selection of the automated driving route is accepted,
wherein the parking position information obtaining step includes the steps of obtaining an on-board apparatus ID identifying the on-board apparatus of the autonomous vehicle stored in a memory in advance with respect to a terminal ID identifying the terminal apparatus, requesting the on-board apparatus of the obtained on-board ID to transmit vehicle position information indicating a present location, and recognizing the location of the parking space based on the vehicle position information uploaded from the on-board apparatus, and
the second search step includes the step of searching the walking travel route to the parking space of the autonomous vehicle based on the present location of the terminal apparatus and the location of the recognized parking space.

2. The method for selecting a route according to claim 1 , further comprising:
a selection step of selecting as a recommended route either the automated driving route or the walking travel route, wherein
the display step includes differentiating a display appearance of the automated driving route or the walking travel route that is selected in the selection step from a display appearance of the walking travel route or the automated driving route that is not selected in the selection step.

3. The method for selecting a route according to claim 2 , wherein the selection step includes selecting the walking travel route when a difference between the second estimated time and the first estimated time is greater than a preset time.

4. The method for selecting a route according to claim 2 , wherein the selection step includes selecting the automated driving route when a walking distance by following the walking travel route is longer than a preset distance.

5. The method for selecting a route according to claim 2 , wherein the selection step including selecting the automated driving route when a parking level of the autonomous vehicle is higher than a preset parking level in a case in which a parking location of the autonomous vehicle is a multilevel parking lot.

6. The method for selecting a route according to claim 2 , wherein the selection step includes selecting either the automated driving route or the walking travel route in accordance with a criterion of environment including at least one of weather and outside-air temperature.

7. The method for selecting a route according to claim 1 , wherein while the autonomous vehicle drives by automated driving following the driving route, when failure occurs in the autonomous vehicle or when an obstacle is present in the travel direction of the autonomous vehicle and the obstacle blocks the travel of the autonomous vehicle, the present position information indicating a present location of the autonomous is obtained from the on-board apparatus, and the display step includes the step of displaying a cause that it is impossible to drive by automated driving, and displaying the walking travel route from the present location of the terminal apparatus to the present location of the autonomous vehicle at the display of the terminal apparatus.

8. A terminal apparatus, comprising:
a processor and a display,
wherein the processor
accepts an operation of an autonomous vehicle to start exiting from a parking space;
obtains information indicating a location of the parking space from an on-board apparatus of the autonomous vehicle when accepting the operation to start exiting from a parking as a trigger;
obtains terminal position information indicating a present location of the terminal apparatus;
calculates an automated driving route of the autonomous vehicle, the automated driving route being from the parking space to the present location of the terminal apparatus, and that calculates a first estimated time in which the autonomous vehicle reaches the present location of the terminal apparatus in a case in which the autonomous vehicle drives by following the automated driving route;
calculates a walking travel route in a case of traveling by walk from a location of the terminal to the parking space and that calculates a second estimated time to reach the parking space in a case of walking by following the walking travel route;
displays the automated driving route and the first estimated time, and the walking travel route and the second estimated time at the display, and presents both of the first estimated time and the second estimated time to the user;
accepts a selection of either the automated driving route or the walking travel route which is selected by the user;
transmits instruction information for instructing the autonomous vehicle to start driving by automated driving when the acceptor accepts a selection of the automated driving route, and
wherein the processor obtains an on-board apparatus ID identifying the on-board apparatus of the autonomous vehicle stored in a memory in advance with respect to a terminal ID identifying the terminal apparatus, requests the on-board apparatus of the obtained on-board ID to transmit vehicle position information indicating a present location, and recognizes the location of the parking space based on the vehicle position information uploaded from the on-board apparatus, and
the processor searches the walking travel route to the parking space of the autonomous vehicle based on the present location of the terminal apparatus and the location of the recognized parking space.

9. A non-transitory computer readable medium including computer program that causes a computer to execute a process, the process comprising:
an operation to start exiting from a parking acceptance procedure of operating an autonomous vehicle to start exiting from a parking space via a terminal apparatus owned by a user;
a parking position information obtaining procedure of obtainin
