Abstract
An example wireless communication system receives signals from several wireless systems such as for example a tire pressure monitoring (TPM) system, a remote keyless entry (RKE) system, and a passive start and entry (PASE) system. Each of the systems provides different signals of different frequencies and modulations. The example receiver includes multiple channels that correspond to the signals from each of the example systems. Each of the channels is operable concurrently to monitor and receive signals from each of the system according to a desired hierarchy. The multiple channels eliminate transmission collisions between signals from the different systems.
Claims15
A communication system for a motor vehicle comprising:
- a receiver including a plurality of channels that are each configured to receive a desired radio frequency signal;
- and
- a controller for controlling receipt of signals on the plurality of channels.
A method of operating a communication system for a motor vehicle comprising the steps of:
- a) monitoring a plurality of channels concurrently with a receiver disposed within a motor vehicle;
- b) switching to a single one of the plurality of channels responsive to detecting a radio frequency signal corresponding one of the plurality of channels;
- and
- c) receiving the radio frequency signal on the one of the plurality of channels.
