Abstract

A remote control system includes a remote control transmitter that transmit a signal and a receiver than can receive the signal from the transmitter. A control device performs a function having a first and a second option. The control device responds to the signal received by the receiver and performs the first option if the distance between the remote control transmitter and the receiver is greater than a particular distance and performs a function based on the ambient noise level.

Claims

1-21. -21. (Cancelled)

22-1. The vehicle according to claim 21, wherein the confirmatory signals include at least two audible signals, a first audible signal being louder than a second audible signal, the control device causing the confirmation device to produce the first audible signal when the ambient noise level is greater than a predetermined level and to produce the second audible signal when the ambient noise level is less than the predetermined level.

26. A method of controlling a remote function comprising:

providing a remote control transmitter and a receiver;

sending a signal from the remote control transmitter to the receiver;

determining the ambient noise level in the area;

performing a first function in response to the signal from the transmitter if the ambient noise level is less than a first predetermined level; and

performing a second function in response to the signal from the transmitter if the ambient noise level is greater than a second predetermined level.

27. The method according to claim 26, wherein the first function includes producing a first audible signal and the second function includes producing a second audible signal that is louder than the first audible signal.

28. The method according to claim 26, wherein the first function includes not producing an audible signal and the second function includes producing an audible signal.

29. The method according to claim 26, wherein the first and second predetermined levels are the same level.

30. A method of controlling a remote function comprising:

providing a remote control transmitter and a receiver;

sending a signal from the remote control transmitter to the receiver;

determining an ambient noise level;

performing a function in response to the signal from the remote control transmitter;

producing a first confirmatory signal having an adjustable output level, the output level being adjusted based on the ambient noise level.

31. The method according to claim 30, wherein the confirmatory signal is an audible signal and the signal loudness is adjusted based on the ambient noise level, the loudness increasing with increasing ambient noise level.

32. A remote control system comprising:

a remote control transmitter operable to transmit a signal;

a receiver operable to receive the signal from the remote control transmitter;

an ambient noise sensor operable to determine the ambient noise level;

a control device responsive to the signal received by the receiver and operable to produce an audible signal if the ambient noise level is greater than a first predetermined level and to not produce an audible signal if the ambient noise level is less than a second predetermined level.

33. The remote control system according to claim 32, wherein the control device is further operable to control a function of a vehicle.

34. The remote control system according to claim 32, wherein the first and second predetermined levels are the same level.

35. The remote control system according to claim 32, wherein the ambient noise sensor is a microphone.
