Tire parameter sensing system with signal relay device 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 for sensing a parameter of the at least one tire and for transmitting a tire parameter signal indicative of the sensed parameter;
a transceiver device located on the vehicle for receiving the tire parameter signal and for transmitting a relay signal indicative of the received tire parameter signal;
a vehicle-based unit mounted on the vehicle in a location spaced away from the transceiver device, the vehicle-based unit adapted to receive both the tire parameter signal and the relay signal; and
an indicator coupled to the vehicle-based unit for providing an indication of the sensed parameter of the at least one tire, the vehicle-based unit controlling the indicator in response to receiving at least one of the tire parameter signal and the relay signal.

Abstract
A tire parameter sensing system (12) comprises a tire-based unit (28) associated with a tire (20) of a vehicle (10) for sensing a parameter of the tire (20) and for transmitting a tire parameter signal (42) indicative of the sensed parameter. A transceiver device (34) receives the tire parameter signal (42) and transmits a relay signal (42′) indicative of the received tire parameter signal (42). A vehicle-based unit (32) is adapted to receive both the tire parameter signal (42) and the relay signal (42′). An indicator (54) is coupled to the vehicle-based unit (32) for providing an indication of the sensed parameter of the tire (20). The vehicle-based unit (32) controls the indicator (54) in response to receiving at least one of the tire parameter signal (42) and the relay signal (42′).

13. A method of monitoring a parameter of at least one tire of a vehicle, the method comprising the steps of:
-
sensing the parameter of the at least one tire;
transmitting a tire parameter signal indicative of the sensed parameter;
receiving the tire parameter signal at a first location;
transmitting a relay signal from the first location, the relay signal being indicative of the received tire parameter signal;
monitoring at a second location for both the tire parameter signal and the relay signal; and
displaying an indication of the sensed parameter in response to receiving at least one of the tire parameter signal and the relay signal at the second location. - View Dependent Claims (14, 15, 16, 17)
