Abstract:
1. A method for receiving signals at a vehicle, the method comprising: configuring a receiver at the vehicle to tune to a first frequency channel having a first set of frequencies in order for the receiver to receive a remote keyless entry (RKE) signal transmitted from a key fob at a transmission frequency falling within the first frequency channel; configuring the receiver to tune from the first frequency channel to a second frequency channel, which has a second set of frequencies disjoint from the first set of frequencies, in order for the receiver to receive a passive entry signal transmitted from the key fob at a transmission frequency falling within the second frequency channel; maintaining the tuning of the receiver to the second frequency channel until the passive entry signal from the key fob has been received by the receiver; receiving by the receiver the passive entry signal from the key fob while the receiver is tuned to the second frequency channel; and configuring the receiver to tune from the second frequency channel back to the first frequency channel upon reception by the receiver of the passive entry signal from the key fob.
