Abstract

A vehicle travel control system for a parking lot controls traveling of at least a first vehicle and a second vehicle through at least a first radio communication circuit and a second radio communication circuit. The vehicle travel control system for a parking lot causes the first vehicle to travel in a direction of moving away from a third vehicle along a first traveling direction and causes the second vehicle to travel between the first vehicle and the third vehicle when the following conditions are satisfied: the first vehicle is stopped in a parking area, the third vehicle is stopped in a passage area adjacent to the parking area to stand still on a path in the first traveling direction in which the first vehicle travels, the first vehicle stopped in the parking area is in a given state, the third vehicle stopped in the passage area is not in the given state, a first distance measured by the first vehicle is smaller than a given width of the second vehicle, and a sum of the first distance and second distance measured by the first vehicle is larger than the given width of the second vehicle.

First claim

What is claimed is:

1 . A vehicle travel control system for a parking lot, the vehicle travel control system comprising:
a first vehicle including a first radio communication circuit and being configured to be externally controlled in traveling, the first vehicle being configured to measure a first distance to an obstacle in a first direction along a first traveling direction and a second distance to an obstacle in a second direction opposite to the first direction along the first traveling direction; a second vehicle including a second radio communication circuit and being configured to be externally controlled in traveling, the second vehicle having a given width in a direction perpendicular to a second traveling direction; and a third vehicle, wherein the vehicle travel control system controls traveling of at least the first vehicle and the second vehicle through at least the first radio communication circuit and the second radio communication circuit, and wherein when the first vehicle is stopped in a parking area, the third vehicle is stopped in a passage area adjacent to the parking area to stand still on a path in the first traveling direction in which the first vehicle travels, the first vehicle stopped in the parking area is in a given state, the third vehicle stopped in the passage area is not in the given state, the first distance measured by the first vehicle is smaller than the given width of the second vehicle, and a sum of the first distance and the second distance measured by the first vehicle is larger than the given width of the second vehicle, the first vehicle is caused to travel in a direction of moving away from the third vehicle along the first traveling direction, and the second vehicle is caused to travel between the first vehicle and the third vehicle.

2 . The vehicle travel control system for a parking lot according to claim 1 , wherein
when the first vehicle is stopped in the parking area, the third vehicle is stopped in the passage area adjacent to the parking area to stand still on a path in the first traveling direction in which the first vehicle travels, the first vehicle stopped in the parking area is in the given state, the third vehicle stopped in the passage area is not in the given state, and a sum of the first distance and the second distance measured by the first vehicle is larger than the given width of the second vehicle, the first vehicle is caused to travel a given distance in a direction of moving away from the third vehicle along the first traveling direction and stop, and the second vehicle is caused to travel between the first vehicle and the third vehicle.

3 . The vehicle travel control system for a parking lot according to claim 1 , wherein
when the first vehicle is stopped in the parking area, the third vehicle is stopped in the passage area adjacent to the parking area to stand still on a path in the first traveling direction in which the first vehicle travels, the first vehicle stopped in the parking area is in the given state, the third vehicle stopped in the passage area is not in the given state, the first distance measured by the first vehicle is smaller than the given width of the second vehicle, and a sum of the first distance and the second distance measured by the first vehicle is smaller than the given width of the second vehicle, the first vehicle is prevented from traveling in a direction of moving away from the third vehicle along the first traveling direction.

4 . The vehicle travel control system for a parking lot according to claim 1 , wherein
the given state is a state in which a vehicle is capable of traveling.

5 . The vehicle travel control system for a parking lot according to claim 1 , wherein
the third vehicle includes a third radio communication circuit, and wherein the third vehicle is configured to output a state of the third vehicle through the third radio communication circuit.

6 . The vehicle travel control system for a parking lot according to claim 1 , wherein
the third vehicle is configured to be externally controlled in traveling.

7 . The vehicle travel control system for a parking lot according to claim 1 , comprising:
a fourth radio communication circuit installed stationarily; and a server configured to communicate with the fourth radio communication unit.

8 . The vehicle travel control system for a parking lot according to claim 7 , wherein
when the first vehicle is stopped in the parking area, the third vehicle is stopped in the passage area adjacent to the parking area to stand still on a path in the first traveling direction in which the first vehicle travels, the first vehicle stopped in the parking area is in the given state, the third vehicle stopped in the passage area is not in the given state, the first distance measured by the first vehicle is smaller than the given width of the second vehicle, and a sum of the first distance and the second distance measured by the first vehicle is larger than the given width of the second vehicle, the server causes the first vehicle to travel in a direction of moving away from the third vehicle along the first traveling direction, and causes the second vehicle to travel between the first vehicle and the third vehicle.

9 . The vehicle travel control system for a parking lot according to claim 1 , wherein
the first vehicle is provided as at least a plurality of vehicles.

10 . The vehicle travel control system for a parking lot according to claim 1 , wherein
the parking area has at least a first parking area and a second parking area, wherein the passage area is located between the first parking area and the second parking area, and wherein the first vehicle is allowed to park in at least one of the first parking area and the second parking area.

11 . A control method of a vehicle travel control system for a parking lot,
the vehicle travel control system including: a first vehicle including a first radio communication circuit and being configured to be externally controlled in traveling, the first vehicle being configured to measure a first distance to an obstacle in a first direction along a first traveling direction and a second distance to an obstacle in a second direction opposite to the first direction along the first traveling direction; a second vehicle including a second radio communication circuit and being configured to be externally controlled in traveling, the second vehicle having a given width in a direction perpendicular to a second traveling direction; and a third vehicle, and the vehicle travel control system being configured to control traveling of at least the first vehicle and the second vehicle through at least the first radio communication circuit and the second radio communication circuit, the control method comprising: when the first vehicle is stopped in a parking area, the third vehicle is stopped in a passage area adjacent to the parking area to stand still on a path in the first traveling direction in which the first vehicle travels, the first vehicle stopped in the parking area is in a given state, the third vehicle stopped in the passage area is not in the given state, the first distance measured by the first vehicle is smaller than the given width of the second vehicle, and a sum of the first distance and the second distance measured by the first vehicle is larger than the given width of the second vehicle, causing the first vehicle to travel in a direction of moving away from the third vehicle along the first traveling direction; and causing the second vehicle to travel between the first vehicle and the third vehicle.
