Abstract

When a reservation signal is received from a portable device, an ECU of a vehicle-side controller detects whether a user is present near a door. When it is detected that the user is present near the door, the ECU of the vehicle-side controller transmits a door unlock command signal and a door opening command signal to the door drive control section for unlocking the lock mechanism of the door. The door drive control section drives a motor of the lock mechanism to unlock the door and also open the door the door unlock command signal and the door opening command signal have been received.

Claims

1. A vehicle door controller provided with a vehicle-side controller mounted in a vehicle and a command device in wireless communication with the vehicle-side controller, the command device transmitting a reservation signal to the vehicle-side controller from an outside of the vehicle for making a reservation of automatic opening of one of a plurality of vehicle doors in response to an operation of the command device, the vehicle door controller comprising:

first communication means for receiving the reservation signal transmitted from the command device;

user detecting means for detecting that a user is present near the one of the plurality of vehicle doors; and

drive control means for opening the one of the plurality of vehicle doors when the first communication means has received the reservation signal and the user detecting means detects that the user is present near the one of the plurality of vehicle doors.

2. A vehicle door controller according to claim 1, wherein:

the user detecting means includes second communication means for forming a communication area around the vehicle, the second communication means for carrying out communication in the communication area;

the command device transmits a response signal including an ID code to the second communication means in response to a request signal transmitted from the second communication means;

the user detecting means checks the ID code included in the response signal with a registration code registered in advance; and

if the ID code and the registration code satisfy a predetermined corresponding relation, the user detection means determines that the user is present near the one of the plurality of vehicle doors, and if the ID code and the registration code do not satisfy the predetermined corresponding relation, the user detection means determines that the user is not present near the one of the plurality of vehicle doors.

3. A vehicle door controller according to claim 2, wherein:

the user detecting means starts transmission of the request signal using the second communication means when the first communication means receives the reservation signal.

4. A vehicle door controller according to claim 2, wherein:

the user detecting means transmits the request signal using the second communication means during a predetermined time interval; and

when the reservation signal is received by the first communication means, the communication area formed by the second communication means is increased.

5. A vehicle door controller according to claim 1, wherein:

the user detecting means includes imaging means that captures an image in an area around the one of the plurality of vehicle doors; and

the user detecting means detects that the user is present near the one of the plurality of vehicle doors by recognizing the user based on the captured image.

6. A vehicle door controller according to claim 5, wherein when the capture of the image by the imaging means is started when the user detecting means receives the reservation signal.

7. A vehicle door controller according to claim 1, wherein:

the one of the plurality of vehicle doors includes a backdoor;

the vehicle includes plural rows of seats; and

the vehicle-side controller includes seat drive means for moving a backmost row of the plural rows of seats between a sitting state and a storing state, the seat drive means moving the backmost row of the seat to the storing state when the drive control means opens the backdoor.

8. A vehicle door controller according to claim 7, further comprising:

determining means that determines whether the backmost row of the of the plural rows of seats is capable of being moved to the storing state,

wherein;

the backmost row of the of the plural rows of seats is moved to the storing state when it is determined to be capable of being moved to the storing state; and

the backmost row of the of the plural rows of seats is stopped from being moved when it is determined not to be capable of being moved to the storing state.

9. A vehicle door controller according to claim 8, further comprising:

notification means for providing a notification that the backmost row of the plural rows of seats is not capable of being moved to the storing state.

10. A vehicle door controller according to claim 1, further comprising:

notification means for providing a notification that the one of the plurality of vehicle doors opens when the drive control means opens the one of the plurality of vehicle doors.

11. A vehicle door controller according to claim 1, further comprising:

obstacle detecting means that detects an obstacle near the one of the plurality of vehicle doors, wherein;

the drive control means stops the opening of the one of the plurality of vehicle doors when the obstacle detecting means detects the obstacle.

12. A vehicle door controller according to claim 11, further comprising:

notification means for providing a notification that the opening of the one of the plurality of vehicle doors has stopped when the obstacle detecting means detects the obstacle and the drive control means stops the opening of the one of the plurality of vehicle doors.

13. A vehicle door controller according to claim 1, wherein:

the vehicle-side controller includes state signal transmitting means for transmitting a state signal showing the automatic door opening state of opening the one of the plurality of vehicle doors when it is detected that the user is present near the one of the plurality of vehicle doors; and

the command device includes output means that outputs the state signal transmitted from the communication means.
