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 method is provided for self-aligning a transmitting frequency between a portable transceiving device and a base station transceiving device. A test signal is transmitted from one of a portable or base station transceiving devices to the other of the portable or base station transceiving devices. The test signal has a frequency that varies during the transmission. The varying of the frequency of the test signal generates a plurality of discrete signals. The other of the portable or base station transceiving devices measures a RSSI value of each discrete signal. The other of the portable or base station transceiving devices determines a discrete signal having a maximum RSSI value. At least a portion of a subsequent message from the other of the portable transceiving device or the base station transceiving device is transmitted at an optimum frequency used for the test signal identified by the test result signal.

摘要： A method is provided for monitoring and mitigating exhaust gas emitted from a vehicle in a closable structure. A remote monitoring device within the closable structure is trained in response to a training signal transmitted from a remote transmitter device. A remote engine start signal is intercepted within a receiving circuit of the remote monitoring device during an actual remote engine start operation. The exhaust gas emitted from the vehicle is monitored in response to receiving the remote engine start signal. A determination is made if an exhaust gas concentration level is greater than a predetermined threshold. A control signal is transmitted to a mitigation device for mitigating the exhaust gas within the closable structure when the exhaust gas concentration level is greater than the predetermined threshold.
