摘要： Vehicle information (e.g., status information, calibratable parameters, or diagnostic data) is transmitted from a base station mounted in a vehicle to a portable RKE fob via a radio-frequency signal within a specified average field strength limit. A multi-byte vehicle message is formed and then coded into a multi-bit coded message. The multi-bit coded message is framed into a plurality of packets. The radio-frequency signal is wirelessly transmitted from the base station with a plurality of spaced packet windows having a predetermined duty cycle, each packet window including a respective one of the plurality of packets. The radio-frequency signal within each of the packet windows has a predetermined field strength greater than the average field strength limit and a substantially zero field strength between the packet windows. The predetermined duty cycle results in an actual average field strength for transmitting all of the packets not exceeding the average field strength limit.

摘要： A two way remote communication system for a vehicle includes a fob portion and a vehicle portion. The fob portion includes a fob battery, a fob transceiver, at least one button and at least one display. The vehicle portion includes a vehicle battery, a vehicle transceiver, and at least one electrical component. The timers are synchronized to simultaneously activate and deactivate the transceivers to establish periodic time intervals when the fob transceiver is open to transmission, which establishes idle time for the fob transceiver and reduces the amount of power consumed by the fob battery.

摘要： A system and method for remote monitoring of vehicle tire pressure include monitors in each tire to transmit signals representative of tire pressure and receive control signals for use in regulating transmission of the tire pressure signals. A vehicle receiver receives the tire pressure signals and passive entry signals transmitted by a remote passive entry device. A vehicle transmitter transmits the control signals for use in regulating transmission of the tire pressure signals. A controller on-board the vehicle in communication with the receiver and transmitter conveys tire pressure information to a vehicle occupant based on the tire pressure signals, determines whether the vehicle is occupied based on the passive entry signal, and generates a control signal operative to halt transmission of the tire pressure signals when the vehicle is unoccupied.

摘要： A passive entry system for a vehicle of a particular model communicates with a portable fob that may be located in either an interior and an exterior of the vehicle. An internal antenna is disposed in the interior and an external antenna is disposed in the exterior. At least one amplifier drives at least one of the antennas and has a configurable gain. A controller is coupled to the amplifier for transferring at least one of internal and external software-configured gain values to the amplifier for controlling a transmission power of interrogation signals broadcast by the internal and external antennas, respectively. The software-configured gain values are obtained in an advance calibration procedure with respect to the particular model of the vehicle.
