Abstract

System for controlling vehicular doors includes an initiation system that initiates door opening or closing based on action by an individual that controls vehicular access, and a door control system associated with each door. At least one of the door control systems opens or closes the associated door in response to detection of an action by the individual. The initiation system may include an interrogator that detects the presence of a key fob unique to the vehicle, and the door control systems open or close the doors only when the key fob is determined to be within a threshold distance to the vehicle for a threshold duration. The interrogator may be configured to direct each door control system to open or close the associated door based on a direction of a responsive signal from the key fob such that the door closest to the key fob is controlled.

Claims

1. A system for controlling at least one door of a vehicle, comprising:

an initiation system that initiates opening or closing of the at least one door based on action by an individual that controls access to the vehicle; and

a door control system associated with each door of the vehicle and coupled to said initiation system, at least one of said door control systems opening or closing an associated one of the doors in response to detection of an action by the individual.

2. The system of claim 1, wherein said initiation system comprises an interrogator that detects the presence of a key fob unique to the vehicle, said door control systems being configured to open or close the doors only when the key fob is determined to be within a first threshold distance to the vehicle for a threshold duration.

3. The system of claim 2, wherein said interrogator is configured to direct the at least one of said door control system to open or close the associated door based on a direction of a responsive signal from the key fob such that the door closest to the key fob is opened or closed.

4. The system of claim 2, wherein opening of a door via one of said door control systems is delayed after initial detection of the presence of the key fob until the key fob is within a second threshold distance of the vehicle.

5. The system of claim 1, further comprising an obstacle detection system that detects obstacles in an opening or closing path of each door and stops opening or closing movement of the door when an obstacle is detected.

6. The system of claim 1, wherein said initiation system comprises a detection system that detects of the presence of a person or part thereof in a door access area associated with each door, the door access area being that portion of space around the vehicle in which the person will be situated or will place a part of their body to indicate they want the associated door to open.

7. The system of claim 6, wherein said detection system is configured to detect and interpret gestures indicative of a desire to open or close a specific one of the doors of the vehicle, such that said door control systems associated with the specific door is directed to open or close the door based on the gesture interpreted by said detection system.

8. The system of claim 6, wherein said initiation system is configured to perform biometric recognition a person in the door access area and initiate opening or closing of the at least one door via said door control systems only when the person is biometrically recognized.

9. The system of claim 8, wherein said initiation system further comprises an interrogator that detects the presence of a key fob unique to the vehicle such that said initiation system initiates opening or closing of the at least one door via said door control systems only when the person is biometrically recognized and the key fob is determined to be within a first threshold distance to the vehicle for a threshold duration.

10. The system of claim 6, wherein said detection system is configured to receive waves and convert reception of waves into an indication of the presence of a person or part thereof in the door access area.

11. The system of claim 1, wherein said initiation system comprises a responsive system that monitors sounds originating within a passenger compartment of the vehicle and determines when sound indicative of a command to open or close a door of the vehicle is present.

12. The system of claim 1, wherein said initiation system comprises a responsive system that monitors gestures by an occupant of a passenger compartment of the vehicle and determines when a gesture indicative of a desire to open or close a door of the vehicle is present.

13. The system of claim 12, wherein said responsive system is configured to apply pattern recognition to recognize gestures by the occupant.

14. The system of claim 12, wherein said responsive system is configured to determine which one of the doors is to be opened or closed based on the recognized gesture.

15. The system of claim 1, wherein said initiation system comprises a button accessible to an occupant of the vehicle.

16. The system of claim 15, further comprising an interlock that prevent said button from causing said door control system to open or close the associated door unless a vehicle transmission is in park or a vehicle ignition is in an off position.

17. The system of claim 1, wherein said initiation system comprises a pivotable steering wheel and pivotal movement of the steering wheel is correlated to opening or closing of a driver'"'"'s door of the vehicle by said door control system associated with the driver'"'"'s door.

18. The system of claim 17, wherein said initiation system comprises a sensing system that detects angular position or movement of the steering wheel, upward angular movement above a threshold causing opening of the driver'"'"'s door and downward angular movement above a threshold causing closing of the door.

19. The system of claim 18, further comprising an interlock that prevent pivotal movement of the steering wheel from causing said door control system to open or close the driver'"'"'s door unless a vehicle transmission is in park or a vehicle ignition is in an off position.

20. The system of claim 1, wherein said initiation system comprises at least one pressure-sensitive area on a steering wheel and depression of the at least one pressure-sensitive area is correlated to opening or closing of a driver'"'"'s door of the vehicle by said door control system associated with the driver'"'"'s door.
