## Abstract

A parking assistance device that assists parking of a vehicle includes: a position acquiring unit that acquires a vehicle position as a position of the vehicle; a route acquiring unit that acquires a plurality of routes as routes from the vehicle position to a plurality of parking positions; a judging unit that judges whether execution of automatic parking is possible, the automatic parking being such that the vehicle travels on any one of the plurality of routes and is parked in the parking position; a suggesting unit that, when execution of the automatic parking is possible, suggests the automatic parking before the vehicle passes through a junction of the plurality of routes; and a parking control unit that executes the automatic parking using the selected route.

## Claims

### Claim 1

A parking assistance device that assists parking of a vehicle, comprising:
a position acquiring unit configured to acquire a vehicle position as a position of the vehicle;
a route acquiring unit configured to acquire a plurality of routes from the vehicle position to each of a plurality of parking positions, the plurality of routes being connected by a junction;
a judging unit configured to judge whether execution of automatic parking is possible, the automatic parking being such that the vehicle travels on at least one of the plurality of routes and is parked in a corresponding one of the plurality of parking positions;
a suggesting unit configured to, when execution of the automatic parking is possible, suggest the automatic parking before the vehicle passes through a junction between a route to a parking position where execution of the automatic parking is possible and another route; and
a parking control unit configured to execute the automatic parking using a route for executing the automatic parking that has been suggested.

### Claim 2 (depends on 1)

The parking assistance device according to claim 1,
wherein the suggesting unit is configured to determine the junction as a standard point immediately preceding a standard point at which a distance between each of a plurality of standard points and a corresponding one of a plurality of corresponding points becomes equal to or greater than a predetermined threshold distance for the first time when seen in order from the vehicle, the plurality of standard points indicating a standard route that is one of the plurality of routes, and the plurality of corresponding points being points on another route that is a route different from the standard route and corresponding to the plurality of standard points respectively.

### Claim 3 (depends on 1)

The parking assistance device according to claim 1, wherein
the suggesting unit is configured to suggest the plurality of routes, and
the parking control unit is configured to perform the automatic parking in which the vehicle travels on the route selected by a driver of the vehicle.

### Claim 4 (depends on 2)

The parking assistance device according to claim 2, wherein
the suggesting unit is configured to suggest the plurality of routes, and
the parking control unit is configured to perform the automatic parking in which the vehicle travels on the route selected by a driver of the vehicle.

### Claim 5 (depends on 1)

The parking assistance device according to claim 1, wherein
the suggesting unit is configured to perform the suggestion at a location where a distance between the vehicle and the junction is equal to or less than a predetermined suggestion distance.

### Claim 6 (depends on 2)

The parking assistance device according to claim 2, wherein
the suggesting unit is configured to perform the suggestion at a location where a distance between the vehicle and the junction is equal to or less than a predetermined suggestion distance.

### Claim 7 (depends on 1)

The parking assistance device according to claim 1,
wherein the suggesting unit is configured to perform the suggestion at a location where a time to arrival of the vehicle at the junction is equal to or less than a predetermined suggestion time.

### Claim 8 (depends on 2)

The parking assistance device according to claim 2,
wherein the suggesting unit is configured to perform the suggestion at a location where a time to arrival of the vehicle at the junction is equal to or less than a predetermined suggestion time.

### Claim 9

A parking assistance method executed by a parking assistance device that assists parking of a vehicle, comprising:
a position acquiring step of acquiring a vehicle position as a position of the vehicle;
a route acquiring step of acquiring a plurality of routes from the vehicle position to each of a plurality of parking positions, the plurality of routes being connected by a junction;
a judging step of judging whether execution of automatic parking is possible, the automatic parking being such that the vehicle travels on at least one of the plurality of routes and is parked in a corresponding one of the plurality of parking positions;
a suggesting step of suggesting, when execution of the automatic parking is possible, the automatic parking before the vehicle passes through a junction between a route to a parking position where execution of the automatic parking is possible and another route; and
a parking control step of executing the automatic parking using a route for executing the automatic parking that has been suggested.
