Abstract

A system for remotely controlling the position of a land vehicle door includes a hand-held communication device such as a key fob having a low-power setting and a high-power setting for wirelessly transmitting low-power command signals and high-power command signals, respectively. Each of the command signals containing command data which identifies a command issued by a pedestrian carrying the hand-held device and identification data which identifies the hand-held device. A mobile communication device is supported on the vehicle for movement therewith and is capable of wirelessly receiving the high-power and low-power command signals. Control logic is coupled to the devices. The hand-held and mobile communication devices automatically transmit and receive, respectively, the low-power command signals as long as a pedestrian carrying an authorized hand-held device is within a predetermined short range of the mobile device.

Claims

1. A system for remotely controlling the position of a land vehicle door externally of the vehicle, the door being capable of moving between a closed position in which the door covers a vehicle opening and an opened position in which the door uncovers the opening to provide access to the vehicle, the system comprising:

a hand-held communication device having a low-power setting and a high-power setting for wirelessly transmitting externally of the vehicle low-power command signals and high-power command signals, respectively, drawn from an energy storage element within the hand-held communication device, each of the command signals containing command data which identifies a command issued by a pedestrian carrying the hand-held device and identification data which identifies the hand-held device;

a mobile communication device supported on the vehicle for movement therewith and capable of wirelessly receiving the high-power and low-power command signals, the mobile device being operative to remove the identification and command data from the command signals; and

control logic coupled to the devices and operative to determine if the hand-held device is an authorized hand-held device based on the identification data and operative to generate door-opening command signals based on the command data wherein the hand-held and mobile communication devices are capable of wirelessly transmitting and receiving, respectively, the high-power, command signals as long as a pedestrian carrying the hand-held device is within a first range of the mobile device and wherein the hand-held and mobile communication devices automatically transmit and receive, respectively, the low-power command signals as long as a pedestrian carrying an authorized hand-held device is within a second range of the mobile device and wherein the second range is less than the first range.

2. The system as claimed in claim 1, wherein each of the devices includes a transceiver and wherein the transceivers communicate via two-way wireless communication.

3. The system as claimed in claim 1, wherein the hand-held device includes a user interface coupled to the control logic and wherein the control logic is operative to determine whether the pedestrian carrying the hand-held device has activated the user interface to transmit the high-power command signal.

4. The system as claimed in claim 3, wherein the user interface includes a push button dedicated to opening the vehicle door.

5. The system as claimed in claim 1, wherein the hand-held device is a key fob.

6. The system as claimed in claim 1, wherein the energy storage element comprises a battery.

7. A key fob for use in a system for remotely controlling the position of a land vehicle door externally of the vehicle, the door being capable of moving between a closed position in which the door covers a vehicle opening and an opened position in which the door uncovers the opening to provide access to the vehicle, the system having a mobile communication device supported on the vehicle for movement therewith and capable of wirelessly receiving high-power and low-power command signals, the mobile device being operative to remove identification and command data contained within the command signals, the key fob comprising:

a hand-held communication device having a low-power setting and a high-power setting for wirelessly transmitting externally of the vehicle low-power command signals and high-power command signals, respectively, drawn from an energy storage element within the hand-held communication device, each of the command signals containing command data which identifies a command and identification data which identifies the hand-held device; and

control logic coupled to the hand-held device and operative to determine if the key fob is an authorized key fob based on the identification data wherein the key fob is capable of wirelessly transmitting the high-power, command signals as long as a pedestrian carrying the key fob is within a first range of the mobile device and wherein the key fob automatically transmits a low-power command signal as long as a pedestrian carrying an authorized key fob is within a second range of the mobile device, and wherein the second range is less than the first range.

8. The key fob as claimed in claim 7, further comprising a transceiver which communicates via two-way wireless communication.

9. The key fob as claimed in claim 7, further comprising a user interface coupled to the control logic and wherein the control logic is operative to determine whether the pedestrian carrying the key fob has activated the user interface to transmit the high-power command signal.

10. The key fob as claimed in claim 9, wherein the user interface includes a push button dedicated to opening the vehicle door.

11. The key fob as claimed in claim 7, wherein the energy storage device element comprises a battery.

12. A system for remote actuation of a vehicle function, the system comprising:

a hand-held device capable of wirelessly transmitting from externally of the vehicle low-power command signals and high-power command signals, respectively, drawn from an energy storage element within the hand-held device, each of the command signals containing command data for actuation of a vehicle function and identification data which identifies the hand-held device;

a mobile communication device associated with the vehicle and capable of wirelessly communicating the high-power and low-power command signals, the mobile device being operative to remove the identification and command data from the command signals; and

control logic coupled to the devices and operative to determine if the hand-held device is an authorized hand-held device based on the identification data and operative to execute the vehicle function of the command data wherein the hand-held and mobile communication devices wirelessly communicate with one another the high-power, command signals when the hand-held device is within a first range of the mobile device and wherein the hand-held and mobile communication devices automatically transition to communicate the low-power command signals when an authorized hand-held device is within a second range of the mobile device and wherein the second range is less than the first range.
