Abstract

A vehicle door controlling device includes a vehicle-side controller, installed on the vehicle including a door capable of being opened automatically; and a mobile device on which reservation setting of automatic door-opening of the door can be made by a user. The mobile device includes a transmitter unit configured to transmit a signal that includes information about the reservation setting, by a wireless communication function. The vehicle-side controller includes a receiver unit configured to receive the signal transmitted from the mobile device, a first detection unit configured to detect the mobile device having the reservation setting and existing in a first area around the door, based on the signal received by the receiver unit, and a control unit configured to unlock the door when the mobile device having the reservation setting has been detected in the first area by the first detection unit, and to open the door when the mobile device detected in the first area by the first detection unit is further being detected in the first area for a predetermined time.

First claim

1 . A vehicle door controlling device, comprising:
a vehicle-side controller, installed on the vehicle including a door capable of being opened automatically; and a mobile device on which a reservation setting of automatic door-opening of the door can be made by a user, wherein the mobile device includes a transmitter unit configured to transmit a signal that includes information about the reservation setting, by a wireless communication function, wherein the vehicle-side controller includes a receiver unit configured to receive the signal transmitted from the mobile device, a first detection unit configured to detect the mobile device having the reservation setting and existing in a first area around the door, based on the signal received by the receiver unit, and a control unit configured to unlock the door when the mobile device having the reservation setting has been detected in the first area by the first detection unit, and to open the door when the mobile device detected in the first area by the first detection unit is further being detected in the first area for a predetermined time.

2 . The vehicle door controlling device as claimed in claim 1 , wherein the control unit reduces door-opening speed of the door slower than normal speed when opening the door.

3 . The vehicle door controlling device as claimed in claim 2 , wherein the control unit reduces the door-opening speed of the door slower than the normal speed when opening the door, until the door reaches a predetermined position between a start point and an end point on an opening trajectory of the door.

4 . The vehicle door controlling device as claimed in claim 1 , wherein the control unit pauses opening the door after having started opening the door.

5 . The vehicle door controlling device as claimed in claim 1 , wherein the vehicle includes a plurality of the doors,
wherein the first detection unit is further configured to be capable of detecting in which one of the first areas corresponding to the respective doors, the mobile device having the reservation setting exists, wherein the control unit opens the door that corresponds to the first area in which the mobile device having the reservation setting has been detected by the first detection unit.

6 . A vehicle door controlling device, comprising:
a vehicle-side controller, installed on the vehicle including a door capable of being opened automatically; and a mobile device on which a reservation setting of automatic door-opening of the door can be made by a user, wherein the mobile device includes a transmitter unit configured to transmit a signal that includes information about the reservation setting, by a wireless communication function, wherein the vehicle-side controller includes a receiver unit configured to receive the signal transmitted from the mobile device, a first detection unit configured to detect the mobile device having the reservation setting, and existing in a first area around the door, based on the signal received by the receiver unit, a second detection unit configured to detect the mobile device existing in a second area included the first area and formed on a side approaching the door in the first area, based on the signal received by the receiver unit, and a control unit configured to unlock the door when the mobile device having the reservation setting has been detected in the first area by the first detection unit, and to open the door when the mobile device detected in the first area by the first detection unit is further detected in the second area by the second detection unit.

7 . The vehicle door controlling device as claimed in claim 6 , wherein the control unit reduces door-opening speed of the door slower than normal speed when opening the door.

8 . The vehicle door controlling device as claimed in claim 7 , wherein the control unit reduces the door-opening speed of the door slower than the normal speed when opening the door, until the door reaches a predetermined position between a start point and an end point on an opening trajectory of the door.

9 . The vehicle door controlling device as claimed in claim 6 , wherein the control unit pauses opening the door after having started opening the door.

10 . The vehicle door controlling device as claimed in claim 1 , wherein the vehicle includes a plurality of the doors,
wherein the first detection unit is further configured to be capable of detecting in which one of the first areas corresponding to the respective doors, the mobile device having the reservation setting exists, wherein the control unit opens the door that corresponds to the first area in which the mobile device having the reservation setting has been detected by the first detection unit.
