Vehicle communication for tire sensor initiation and vehicle keyless entry via a shared resource
First Claim
1. A communication system for a vehicle, said system comprising:
- a portable identification device for keyless entry into the vehicle, including means for receiving an interrogation signal and means for transmitting an identification indicative signal responsive to the interrogation signal;
a tire sensor device for providing information regarding a condition at a tire of the vehicle, including means for sensing at least one tire condition, means for receiving an initiation signal, and means for transmitting a condition indicative signal responsive to the initiation signal; and
a transmitter arrangement for emitting the interrogation signal at a first frequency and the initiation signal at a second, different frequency, said transmitter arrangement including at least one component that is operable for provision of both the interrogation signal at the first frequency and the initiation signal at the second frequency.

Abstract
A communication system (10) for a vehicle (12) includes a portable identification device (32) for keyless entry into the vehicle (12) and a tire sensor device (e.g., 48A) for providing information regarding a condition at a tire (e.g., 46A) of the vehicle (12). The portable identification device (32) includes an antenna (110) for receiving an interrogation signal (36) and for transmitting an identification indicative signal (38) responsive to the interrogation signal. The tire sensor device (48A) includes a sensor (158) for sensing at least one tire condition. The tire sensor device (48A) includes antennas (148 and 172) for receiving an initiation signal (e.g., 66A) and for transmitting a condition indicative signal (e.g., 50A) responsive to the initiation signal. The system (10) includes a transmitter arrangement (e.g., 72A, 28A, and 64A) for emitting the interrogation signal (36) at a first frequency and the initiation signal (66A) at a second, different frequency. The transmitter arrangement includes at least one component (72A) that is operable for provision of both the interrogation signal and the initiation signal.

12. A communication method for a vehicle, said system comprising:
-
operating at least one component for transmission of an interrogation signal at a first frequency;
receiving the interrogation signal at a portable identification device for keyless entry into the vehicle;
transmitting an identification indicative signal from the portable identification device responsive to the interrogation signal;
operating said at least one component for transmission of an initiation signal at a second, different frequency;
receiving the initiation signal at a tire condition sensor device; and
transmitting a condition indicative signal, which is indicative of at least one sensed tire condition, from the tire condition sensor device responsive to the initiation signal.
