Abstract

Portable devices are provided to occupants, who frequently use a vehicle. Based on a result of verification of an ID code of respective portable devices through intercommunication between the respective portable devices and a vehicle side unit, a number and a location of the occupant, who approaches the vehicle to get into a passenger compartment of the vehicle, are sensed. Based on the sensed result, a position of a seat, which is predicted to be used by the corresponding occupant, is changed.

Claims

1. A vehicle control system comprising:

a sensing means for sensing a number and a location of at least one occupant, who approaches a vehicle to get into a passenger compartment of the vehicle; and

a position changing means for changing a position of at least one predicted seat of the vehicle, on which the at least one occupant is predicted to be seated, to increase an available space for occupant entry based on a sensed result of the sensing means.

2. The vehicle control system according to claim 1, wherein when it is predicted that two or more occupants are included in the at least one occupant and are going to get into the passenger compartment through a first row seat door and a second row seat door, which are on the same side of the vehicle and correspond to a first row seat and a second row seat, respectively, based on the sensed result of the sensing means, the position changing means sets a seat position of the first row seat in a front side position, which is closer to a front side of the vehicle, in comparison to a case where it is predicted that only the first row seat door, which corresponds to the first row seat, is going to be used by the at least one occupant.

3. The vehicle control system according to claim 1, wherein:

first to third row seats are provided to the passenger compartment;

the position changing means determines whether the third row seat is going to be used by at least one of the at least one occupant based on the sensed result of the sensing means; and

when the position changing means determines that the third row seat is going to be used by the at least one of the at least one occupant, the position changing means moves the second row seat, which corresponds to a door that is predicted to be used by the at least one of the at least one occupant, in a transverse direction of the vehicle away from the door.

4. The vehicle control system according to claim 1, further comprising an entry completion determining means for determining whether entry of the at least one occupant into the passenger compartment is completed, wherein the position changing means returns each of the at least one predicted seat to a predetermined position thereof when the entry completion determining means determines that the entry of the at least one occupant into the passenger compartment is completed.

5. The vehicle control system according to claim 4, wherein:

the position changing means stores an adjusted position of at least one of the at least one predicted seat, which is adjusted by a corresponding one of the at least one occupant; and

the position changing means returns a current position of the at least one of the at least one predicted seat to the stored position, which serves as the predetermined position of the at least one of the at least one predicted seat, when the entry completion determining means determines that the entry of the at least one occupant into the passenger compartment is completed.

6. The vehicle control system according to claim 1, wherein when it is predicted that one of the at least one occupant is going to get into a driver seat through a driver seat door, which corresponds to the driver seat, the position changing means moves the driver seat in a rear direction of the vehicle and also moves a steering wheel of the vehicle in an upward direction of the vehicle.

7. The vehicle control system according to claim 6, further comprising an entry completion determining means for determining whether entry of the one of the at least one occupant to the driver seat is completed, wherein the position changing means returns each of the driver seat and the steering wheel to a predetermined position thereof when the entry completion determining means determines that the entry of the one of the at least one occupant to the driver seat is completed.

8. The vehicle control system according to claim 7, wherein:

the position changing means stores an adjusted position of the driver seat and an adjusted position of the steering wheel, which are adjusted by the one of the at least one occupant; and

the position changing means returns a current position of the driver seat and a current position of the steering wheel to the stored position of the driver seat and the stored position of the steering wheel, respectively, which serve as the predetermined position of the driver seat and the predetermined position of the steering wheel, respectively, when the entry completion determining means determines that the entry of the one of the at least one occupant to the driver seat is completed.

9. The vehicle control system according to claim 1, wherein:

the sensing means includes;

a plurality of portable devices, which are carriable by a plurality of occupants, respectively; and

a vehicle side unit, which is installed in the vehicle;

the vehicle side unit includes;

a plurality of transmitters, which are provided to a plurality of doors, respectively, of the vehicle to have a corresponding communication area around the door and which transmit a request signal to the plurality of portable devices;

a receiver that receives a response signal of each communicatable one of the plurality of portable devices, which replies the response single in response to the request signal; and

a verifying means for verifying whether a predetermined relationship exists between an ID code of the received response signal of each communicatable one of the plurality of portable devices and a corresponding registered ID code, which is preregistered, wherein;

each communicatable one of the plurality of portable devices transmits the response signal, which includes the ID code that is specific to the portable device, when the portable device receives the request signal; and

the sensing means senses the number and the location of the at least one occupant based on a location of each corresponding one of the plurality of transmitters that has transmitted the request signal to a corresponding verified one of the plurality of portable devices, which has the ID code that is verified by the verifying means.

10. The vehicle control system according to claim 1, wherein the sensing means includes a plurality of sensor devices, which are provided to a plurality of doors, respectively, of the vehicle and use one of a light wave, a sound wave and a radio wave as transmission media thereof to sense the at least one occupant.

11. The vehicle control system according to claim 1, wherein the sensing means includes:

a image capturing means for capturing an image of the at least one occupant, each of who approaches the vehicle toward a corresponding door of the vehicle; and

an identifying means for identifying the number and the location of the at least one occupant based on the captured image, which is captured with the image capturing means.
