Patent ID: 6948360

Claim:
A tire parameter sensing system for a vehicle having at least one tire, the tire parameter sensing system comprising: a tire-based unit associated with the at least one tire and including structure for sensing a parameter of the at least one tire and for transmitting a parameter signal indicative of the sensed parameter, the parameter signal having at least first and second different signal characteristics; a vehicle-based unit having first and second receiving channels and a signal detection portion, the first receiving channel receiving at least portions of the parameter signal that include the first signal characteristic and providing a first data signal indicative thereof, the second receiving channel receiving at least portions of the parameter signal that include the second signal characteristic and providing a second data signal indicative thereof, the signal detection portion of the vehicle-based unit receiving the first and second data signals and, in response to the first and second data signals, determining the sensed parameter of the at least one tire.
