1. A communication system for a vehicle comprising:
- a first transmitter for transmitting a first signal relating to a first vehicle system;
a second transmitter for transmitting a second signal relating to a second vehicle system that is different than the first vehicle system, said first and second signals each having a modulation that is different than the other;
a sensor configured to send a switching signal in response to a sensed condition;
a receiver in communication with said sensor and having a first reception mode and a second reception mode, said first reception mode receptive to said first signal and not said second signal and said second mode receptive to said second signal and not said first signal;
a control unit for switching said receiver between said first reception mode and said second reception mode in response to said switching signal;
wherein said control unit is programmed to switch between said first reception mode and said second reception mode based upon at least one sensed condition; and
wherein said control unit is programmed to switch from said first reception mode to said second reception mode when said at least one sensed condition is at a first value relating to vehicle speed and is programmed to switch from said second reception mode to said first reception mode when said at least one sensed condition is at a second value relating to vehicle speed different from said first value.

Abstract
A communication for a vehicle (10) has a first transmitter (34) for transmitting a first signal relating to a first vehicle system (22) and a second transmitter (42) for transmitting a second signal relating to a second vehicle system (38). (FIG. 1) A single receiver (46) has a first reception mode (50) and a second reception mode (54). The first reception mode (50) is receptive to the first signal while the second reception mode (54) is receptive to the second signal. A control unit (58) switches the receiver (46) between the first reception mode (50) and the second reception mode (54).

5. A communication system for a vehicle comprising:
-
a first transmitter for transmitting a first signal relating to a first vehicle system; a second transmitter for transmitting a second signal relating to a second vehicle system, said first and second signals each having a modulation that is different than the other; a sensor configured to send a switching signal in response to a sensed condition; a receiver in communication with said sensor and having a first reception mode and a second reception mode, said first reception mode receptive to said first signal and not said second signal and said second mode receptive to said second signal and not said first signal; and a control unit for switching said receiver between said first reception mode and said second reception mode in response to said switching signal, wherein said control unit is programmed to detect a first condition relating to a presence of a key in a vehicle ignition and a second condition relating to a gear position of a vehicle transmission, said control unit switching between said first reception mode and said second reception mode based upon said first condition and said second condition.

6. A communication system for a vehicle comprising:
-
a first transmitter for transmitting a ASK signal relating to a remote vehicle port actuation system; a second transmitter for transmitting a FSK signal relating to a tire pressure monitoring system; a receiver having a first reception mode and a second reception mode, said first reception mode receptive to said ASK signal and said second mode receptive to said FSK signal; a control unit programmed to switch said receiver between said first reception mode and said second reception mode based upon a sensed condition; and wherein said control unit is programmed to switch between said ASK mode and said FSK mode based upon said sensed condition, which includes vehicle speed, said ASK mode being a default mode, said control unit switching said receiver to FSK mode in response to a predetermined vehicle speed. - View Dependent Claims (7, 8, 9, 10, 11, 12)
