Abstract
A disclosed example receiver for receiving transmissions and data for both a remote keyless entry (RKE) system and a tire pressure monitoring (TPM) system tailors the data slice level to the characteristics unique to each of the RKE transmissions and the TPM transmissions.
Claims15
A receiver assembly for receiving transmissions from a remote keyless entry (RKE) system and a tire pressure monitoring (TPM) system, the receiver assembly comprising:
- a data slicer module including a first mode of operation for receiving a transmission for the RKE system and a second mode of operation different than the first mode of operation for receiving a transmission for the TPM system;
- and
- a controller for switching the data slicer between the first mode and the second mode responsive to an expected transmission from one of the RKE and TPM systems, wherein the controller switches the data slicer between the first mode of operation and the second mode of operation based on a speed of a vehicle in which the receiver assembly is installed.
A receiver assembly for receiving transmissions from a remote keyless entry (RKE) system and a tire pressure monitoring (TPM) system, the receiver assembly comprising:
- a data slicer module including a first mode of operation for receiving a transmission for the RKE system and a second mode of operation different than the first mode of operation for receiving a transmission for the TPM system;
- and
- a controller for switching the data slicer between the first mode and the second mode responsive to an expected transmission from one of the RKE and TPM systems, wherein the controller switches the data slicer to the first mode of operation responsive to a condition indicating that a vehicle in which the receiver assembly is installed is not moving.
A method of receiving transmissions from a remote keyless entry (RKE) system and a tire pressure monitoring (TPM) system comprising the steps of:
- determining which of a RKE transmission and a TPM transmission that is expected;
- and
- modifying the slice level of a receiver responsive to which of the RKE and TPM transmissions are expected, wherein the step of determining which of the RKE and TPM transmissions are expected includes determining a vehicle speed and expecting one of the RKE and TPM transmissions based on vehicle speed.
