Abstract

An in-vehicle device includes: an empty stall determiner that determines, based on sensing of surroundings by a sensor section provided in a vehicle, whether or not a parking stall present in surroundings of the vehicle is an empty stall; an empty stall storing section that stores information regarding a location of the empty stall determined by the empty stall determiner in association with a passing route of the vehicle; and an automatic travel controller that generates a travel route from a current location to the empty stall based on the sensing of the surroundings by the sensor section, the automatic travel controller performing control to cause the vehicle to travel along the travel route and be parked in the empty stall in a head-in manner.

First claim

What is claimed is:

1. An in-vehicle device comprising:
a processor and a memory,
wherein the memory includes an empty stall storing section storing information regarding a location of an empty stall determined by an empty stall determiner in association with a passing route of a vehicle,
wherein the processor includes
an entry determiner determining whether or not the vehicle enters a parking lot;
a location estimator estimating a current location of the vehicle;
a map generator sequentially obtaining the passing route, which is a route where the vehicle has passed from an entry of the parking lot to a getting-out location where an occupant gets out from the vehicle, by tracing the current location estimated by the location estimator while the vehicle is in the parking lot;
the empty stall determiner determining, based on sensing of surroundings by a sensor section provided in the vehicle, along the passing route, whether or not a parking stall present in surroundings of the vehicle is the empty stall;
a notification controller outputting a notification to the occupant regarding the getting-out location and the location of a target parking stall which is the empty stall where the vehicle is to be parked;
an automatic travel controller, based on the sensing of the surroundings by the sensor section, generating an automatic travel route which travels the vehicle along the passing route from the getting-out location, wherein the automatic travel controller controls the vehicle to travel along the automatic travel route, and when the vehicle reaches at a position where the vehicle starts performing a loading operation into the empty stall, the vehicle is loaded merely by a forward motion without a turning operation to perform a direction change from a reverse motion to the forward motion, and the automatic travel controller performs control to cause the vehicle to be parked; and
a target parking stall setting section setting a new target parking stall which is a new empty stall, when the vehicle reaches the target parking stall, another vehicle is already parked in the target parking stall, from among other empty stalls wherein the new empty stall has a distance to travel to which from the current location is the shortest or the new empty stall is determined to be an empty stall at the latest timing.

2. The in-vehicle device according to claim 1 , wherein the empty stall determiner starts, in response to the vehicle being determined to enter the parking lot, determining whether or not the parking stall present in the surroundings of the vehicle is the empty stall based on the sensing of the surroundings by the sensor section.

3. The in-vehicle device according to claim 1 , wherein the processor further includes a display controller performing control to cause the empty stall where the vehicle is to be parked and another empty stall to be displayed in different manners.

4. A control method for an in-vehicle device that is to be installed in a vehicle, the method comprising:
an entry determination step of determining whether or not the vehicle enters a parking lot;
a location estimation step of estimating a current location of the vehicle;
a map generation step of sequentially obtaining the passing route, which is a route where the vehicle has passed from an entry of the parking lot to a getting-out location where an occupant gets out from the vehicle, by tracing the current location while the vehicle is in the parking lot;
an empty stall determination step of determining, based on sensing of surroundings by a sensor section provided in the vehicle, along the passing route, whether or not a parking stall present in surroundings of the vehicle is an empty stall;
a notification step of outputting a notification to the occupant regarding the getting-out location and the location of a target parking stall which is the empty stall where the vehicle is to be parked;
an empty stall storing step of storing information regarding a location of the empty stall determined in the empty stall determination step in association with a passing route of the vehicle;
an automatic travel control step of, based on the sensing of the surroundings by the sensor section, generating an automatic travel route which travels the vehicle along the passing route from a getting-out location, traveling vehicle along the automatic travel route, and when reaching the vehicle at a position where the vehicle starts performing a loading operation into the empty stall, loading the vehicle merely by a forward motion without a turning operation to perform a direction change from a reverse motion to the forward motion, and performing control to cause the vehicle to be parked; and
a target parking stall setting step of setting a new target parking stall which is a new empty stall, when the vehicle reaches the target parking stall, another vehicle is already parked in the target parking stall, from among other empty stalls wherein the new empty stall has a distance to travel to which from the current location is the shortest or the new empty stall is determined to be an empty stall at the latest timing.

5. The control method according to claim 4 , wherein the determining in the empty stall determination step is started in response to the vehicle being determined to enter the parking lot in the entry determination step.

6. The control method according to claim 4 , further comprising: a display control step of displaying the empty stall where the vehicle is to be parked and another empty stall in different manners.
