SYSTEM AND METHOD FOR PROVIDING A DISTANCE TO TARGET FOR REMOTE KEYLESS ENTRY
First Claim
1. A method for providing a distance to target vehicle finder function for remote keyless entry comprising:
- enabling a vehicle finder function from a portable device;
transmitting a low power signal from the portable device to a vehicle onboard receiver;
determining whether the vehicle onboard receiver receives the low power signal from the portable device;
enabling a low power vehicle finding response upon determination that the vehicle onboard receiver receives the low power signal from the portable device;
transmitting a high power signal from the portable device to the vehicle upon determination that the vehicle onboard receiver does not receive the low power signal from the portable device; and
enabling a high power vehicle finding response upon determination that the vehicle onboard receiver receives the high power signal from the portable device.

Abstract
A method and system for providing a distance to target vehicle finder function for remote keyless entry is provided. The method and system include enabling a vehicle finder function from a portable device and transmitting a low power signal from the portable device to a vehicle onboard receiver. The method and system further includes determining whether the vehicle onboard receiver receives the low power signal from the portable device and enabling a low power vehicle finding response. The method and system also include transmitting a high power signal from the portable device to the vehicle when it is determined that the vehicle onboard receiver does not receive the low power signal from the portable device, and enabling a high power vehicle finding response when it is determined that the vehicle onboard receiver receives the high power signal from the portable device.

9. A system for providing a distance to target vehicle finder function for remote keyless entry comprising:
-
a portable device transmitter provided on a portable device transmitting a low power signal to a vehicle onboard receiver provided in a vehicle; a vehicle finding control module provided on the portable device determining whether the vehicle onboard receiver receives the low power signal from the portable device; and a vehicle finding response module provided in the vehicle enabling a low power vehicle finding response when the vehicle finding control module determines that the vehicle onboard receiver receives the low power signal from the portable device; wherein the portable device transmitter transmits a high power signal to the vehicle onboard receiver when the vehicle finding module does not determine that the vehicle onboard receiver receives the low power signal from the portable device, and the vehicle finding response module enables a high power vehicle finding response when the vehicle finding control module determines the vehicle onboard receiver receives the high power signal from the portable device. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method for providing a distance to target vehicle finder function for remote keyless entry comprising:
-
enabling a vehicle finder function from a portable device; transmitting a low power signal from the portable device to a vehicle onboard receiver based off of a user input of a lock input button on the portable device; determining whether the vehicle onboard receiver receives the low power signal from the portable device; enabling a low power vehicle finding response when it is determined that vehicle onboard receiver receives the low power signal from the portable device; transmitting an initial high power signal from the portable device on a different frequency than the low power signal to the vehicle when it is determined that the vehicle onboard receiver does not receive the low power signal from the portable device; transmitting a secondary high power signal from the portable device on a different frequency than the initial high power signal to the vehicle when it is determined that the vehicle onboard receiver does not receive the initial high power signal from the portable device; and enabling a high power vehicle finding response when it is determined that the vehicle onboard receiver receives the initial or secondary high power signal from the portable device. - View Dependent Claims (18, 19, 20)
