Abstract

An electronic passive entry-passive start (ePEPS) system includes a first satellite ultra-wideband antenna, a second satellite ultra-wideband antenna, a third satellite ultra-wideband antenna, and a fourth satellite ultra-wideband antenna. A remote function actuator is in electronic communication with the first satellite ultra-wideband antenna, the second satellite ultra-wideband antenna, the third satellite ultra-wideband antenna, and the fourth satellite ultra-wideband antenna. A body control module can be in electronic communication with remote function actuator. A key fob is in wireless communication with the first satellite ultra-wideband antenna, the second satellite ultra-wideband antenna, the third satellite ultra-wideband antenna, and the fourth satellite ultra-wideband antenna such that predetermined functions in a vehicle are actuated depending on the position of a user.

Claims

1. An electronic passive entry-passive start (peps) system comprising:

a first satellite ultra-wideband antenna positioned within or on a vehicle;

a second satellite ultra-wideband antenna positioned within or on a vehicle;

a third satellite ultra-wideband antenna positioned within or on a vehicle;

a fourth satellite ultra-wideband antenna positioned within or on a vehicle;

a remote function actuator in electronic communication with the first satellite ultra-wideband antenna, the second satellite ultra-wideband antenna, the third satellite ultra-wideband antenna, and the fourth satellite ultra-wideband antenna; and

a key fob in wireless communication with the first satellite ultra-wideband antenna, the second satellite ultra-wideband antenna, the third satellite ultra-wideband antenna, and the fourth satellite ultra-wideband antenna such that predetermined functions in a vehicle are actuated depending on the position of a user.

2. The system of claim 1 wherein the first satellite ultra-wideband antenna, the second satellite ultra-wideband antenna, the third satellite ultra-wideband antenna, and the fourth satellite ultra-wideband antenna are positioned within a vehicle with a maximum possible separation distance with respect to an axis system in a plane parallel to a vehicle floor.

3. The system of claim 1 wherein at least one ultra-wideband antenna has a maximum separation from other anchors with respect to an axis perpendicular to a plane parallel a vehicle floor.

4. The system of claim 1 operable to open at least one vehicle door when a user with the key fob is within a first predefined distance of a vehicle'"'"'s B pillar.

5. The system of claim 4 wherein the user with the key fob must be within the first predefined distance in order to remotely start the vehicle.

6. The system of claim 4 operable to open a vehicle trunk when a user with the key fob is within a second predefined distance of a vehicle'"'"'s trunk.

7. The system of claim 6 wherein the second predefined distance is less than the first predefined distance.

8. The system of claim 1 operable to lock the vehicle when a user with the key fob crosses from a distance less than a third predefined distance to a distance greater than the third predefined distance.

9. The system of claim 8 wherein the third predefined distance is greater than the first predefined distance and the second predefined distance.

10. The system of claim 7 wherein the first satellite ultra-wideband antenna, second satellite ultra-wideband antenna, third satellite ultra-wideband antenna, fourth satellite ultra-wideband antenna, and the key fob transmit and/or receive a signal in the range of 3 kHz to 300 GHz.

11. The system of claim 7 wherein the first satellite ultra-wideband antenna, second satellite ultra-wideband antenna, third satellite ultra-wideband antenna, fourth satellite ultra-wideband antenna, and the key fob transmit and/or receive a signal with a bandwidth greater than or equal to 500 MHz or 20% of a center frequency.

12. An electronic passive entry-passive start (peps) system comprising:
