SYSTEM AND METHOD FOR REMOTELY CONTROLLING A FUNCTION
First Claim
Patent Images
1. A system for remotely controlling a function, the system comprising:
- a transmitter for transmitting a wireless control signal indicative of a function request;
a receiver for receiving the wireless control signal; and
a receiver control circuit for determining when the function request is indicative of a range-limited function and for measuring an elapsed time value, the elapsed time value being measured from an end of the wireless control signal until a noise signal is detected;
wherein the range-limited function is performed when the wireless control signal is indicative of a range-limited function and the elapsed time value exceeds a threshold value.

9. A method of controlling a function, the method comprising:
-
transmitting a wireless control signal with a transmitter;
receiving the wireless control signal with a receiver;
determining whether the wireless control signal is indicative of a range-limited function;
determining an elapsed time value when the wireless control signal is indicative of a range-limited function, the elapsed time value being measured from an end of the wireless control signal to detection of noise by the receiver; and
performing the range-limited function when the elapsed time value exceeds a threshold value. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method of controlling a vehicle function with a remote keyless entry system having a vehicle-mounted receiver control circuit that includes a receiver and a remote keyless entry fob having a transmitter and an input device, the method comprising:
-
actuating the input device;
transmitting a wireless control signal based on actuation of the input device;
receiving the wireless control signal with the receiver;
decoding the wireless control signal with the receiver control circuit to determine whether the wireless control signal is indicative of a range-limited function or a non-range-limited function;
determining an elapsed time value with the receiver control circuit when the wireless control signal is indicative of a range-limited function, the elapsed time value being measured between an end of the wireless control signal and the presence of a noise signal; and
performing the range-limited function when the wireless control signal is indicative of the range-limited function and the elapsed time value exceeds a threshold value;
wherein the elapsed time value increases as a distance between the transmitter and the receiver decreases. - View Dependent Claims (16, 17, 18, 19, 20)
