Combined tire pressure monitoring and keyless entry receiver
First Claim
1. A system for monitoring conditions within a tire comprising;
- a sensor assembly disposed within each tire of a motor vehicle, a transmitter in communication with said sensor assembly to transmit signals indicative of current tire conditions;
a remote transmitter for actuating a remote keyless entry system, said remote transmitter emitting a signal to actuate a function of said keyless entry system;
a receiver assembly for receiving said signal indicative of said current tire conditions and said single to actuate a function from said remote transmitter, said signal indicative of said tire conditions is different than said signal to actuate a function of said remote keyless entry system.

Abstract
A system for monitoring conditions within a tire (12) including a sensor assembly (14) including a pressure sensor (36), an accelerometer (34), a temperature sensor (32), and a transmitter (40) to transmit signals indicative of current tire conditions. A remote transmitter (22) for actuating a remote keyless entry system (19) emits a signal to actuate a function of the keyless entry system (19) such as unlocking doors (20) of the motor vehicle (10). A receiver assembly (16) includes an amplitude shift keyed receiver (52) and a frequency shift keyed receiver (58) selectively engagable to receive radio frequency transmissions from the tire monitoring system or the remote keyless entry system (19).

25. A method of determining a position of sensor assemblies for a tire pressure monitoring system of a motor vehicle comprising the steps of:
-
a. transmitting a signal indicative of tire acceleration to a receiver assembly;
b. obtaining data indicative of motor vehicle speed from a vehicle system;
c. comparing the signal indicative of tire acceleration with the data indicative of motor vehicle acceleration;
d. recording the sensor assembly identification code in response to the signal indicative of tire acceleration being substantially equal to the data indicative of motor vehicle acceleration.

30. A method of preventing data transmission overlap between signals emitted from a tire pressure monitoring system and a remote keyless entry system, said method comprising the steps of;
-
a. setting a receiver assembly including an amplitude shift keyed receiver and a frequency shift keyed receiver such that incoming transmissions are received by said amplitude shift keyed receiver;
b. switching from said amplitude shift keyed receiver to said frequency shift receiver in response to a triggering event. - View Dependent Claims (31, 32, 33)
