Abstract

A parking controller according to one aspect of an embodiment includes a specific-parking-frame acquiring unit, a target-parking-frame setting unit, and a vacant-parking-frame detecting unit. The specific-parking-frame acquiring unit acquires information indicating a specific parking frame. The specific parking frame is a parking frame that is specified by an external device among from a plurality of parking frames in a parking lot. The target-parking-frame setting unit sets the specific parking frame as a target parking frame. The target parking frame is a parking frame to be a target. The vacant-parking-frame detecting unit detects a vacant parking frame while an own vehicle is travelling to the target parking frame. The vacant parking frame is a parking frame in a vacant state. The target-parking-frame setting unit changes, when the vacant-parking-frame detecting unit detects the vacant parking frame, the set target parking frame into the vacant parking frame.

an another-vehicle determining unit that determines whether or not there exists another travelling vehicle around the vacant parking frame when the vacant-parking-frame detecting unit detects the vacant parking frame; and

a preference-degree determining unit that determines preference degrees of the own vehicle and the other vehicle for the vacant parking frame when the another-vehicle determining unit determines that there exists the other vehicle, wherein

the target-parking-frame setting unit sets the target parking frame based on a determination result of the preference-degree determining unit.

4. The parking controller according to claim 3, wherein the target-parking-frame setting unit changes the target parking frame into the vacant parking frame when the preference degree of the own vehicle for the vacant parking frame is higher than that of the other vehicle.

5. The parking controller according to claim 3, wherein the preference-degree determining unit acquires, for each of the own vehicle and the other vehicle, as corresponding preference degree information at least one of (i) corresponding acquisition time point information on a time at which information indicating the specific parking frame is acquired, (ii) corresponding distance information from a present position to the vacant parking frame, (iii) corresponding vehicle-size information, (iv) corresponding number-of-occupants information, and (v) corresponding history information indicating a use history of the parking lot, and determines the corresponding preference degree based on the acquired corresponding preference degree information.

6. The parking controller according to claim 3, wherein the preference-degree determining unit does not determine the preference degrees when receiving from the other vehicle information indicating a determination result of the preference degrees, for the vacant parking-frame, of the own vehicle and the other vehicle.

7. The parking controller according to claim 1, further comprising:

a predetermined-parking-frame determining unit that determines whether or not the specific parking frame, which is set as the target parking frame, is a predetermined parking frame that satisfies a predetermined condition, wherein

the target-parking-frame setting unit forbids changing the target parking frame into the vacant parking frame when the vacant-parking-frame detecting unit detects the vacant parking frame and the predetermined-parking-frame determining unit determines that the specific parking frame is the predetermined parking frame.

8. The parking controller according to claim 1, further comprising:

a parking-completion determining unit that determines whether or not parking of the own vehicle into the changed target parking frame has completed; and

a transmitting unit that transmits, to the external device, information indicating the changed target parking frame in which the own vehicle is parked, when the parking-completion determining unit determines that the parking into the changed target parking frame has completed.

13. A parking control system comprising:

the parking controller according to claim 1; and

a vehicle controller that controls the vehicle based on a signal output from the parking controller.
