TIRE PARAMETER SENSING SYSTEM HAVING ALTERNATING FREQUENCY TRANSMISSION AND TWO CHANNEL RECEPTION AND ASSOCIATED METHOD
First Claim
1. 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.

Abstract
A tire parameter sensing system (12) for a vehicle (10) having a tire (16) comprises a tire-based unit (26) associated with the tire (16) and including structure (70, 72) for sensing a parameter of the tire (16) and for transmitting a parameter signal (38) indicative of the sensed parameter. The parameter signal (38) having at least first and second different signal characteristics. The tire parameter sensing system (12) also comprises a vehicle-based unit (34) having a first receiving channel (116) for receiving at least portions of the parameter signal (38) that include the first signal characteristic and a second receiving channel (118) for receiving at least portions of the parameter signal (38) that include the second signal characteristic. A signal detection portion (120) of the vehicle-based unit (34) is responsive to the first and second signal characteristics for determining the sensed parameter of the tire (16).
