摘要:
A vehicle tire pressure monitoring (TPM) system, the system including an immobilizer transmitter that transmits at least one low frequency (LF) sensor diagnostic signal, at least one TPM sensor, wherein the at least one TPM sensor includes a transceiver that receives the at least one LF sensor diagnostic signal and, when the at least one TPM sensor is operating properly, presents at least one radio frequency (RF) message signal, and a TPM receiver that receives the at least one RF message signal and provides an indication to an operator when the at least one RF message signal is received, wherein the LF sensor diagnostic signal is transmitted to determine proper operation of the at least one TPM sensor.
摘要:
The present invention provides a vehicle information display and communication system having a plurality of operative modules, the system includes a control processing unit adapted to provide an interface among the plurality of operative modules. The operative modules include a display module adapted to provide visual information to the occupants of the vehicle, a navigation module adapted for global positioning satellite reception to provide vehicle position information to the control processing unit, and a telecommunications module adapted for wireless communication to provide communication between the control processing unit and a wireless telecommunications network and between the control processing unit and any one of a plurality of local wireless devices. The system further includes a local network interface module adapted to provide communication between a vehicle control bus and the control processing unit, and an antenna array including a GPS antenna mounted in an overhead console, the overhead console adapted to extend forward over the upper edge of the vehicle windshield such that GPS antenna maintains line-of-sight with at least one global positioning satellite transmitter at all times.
