摘要:
A vehicle entry/tire pressure monitoring system for a vehicle includes an ECU, LF antennas mounted on the vehicle and being in communication with the ECU, and tire sensors mounted in, on or adjacent respective tires of the vehicle. Each LF antenna is configured to transmit an LF tire sensor wake up field and a SMART entry LF search field to wake up a portable transmission/reception unit for keyless entry of the vehicle tire sensor. Each tire sensor includes a two-axis receiver antenna and an RF transmitter configured to transmit an RF signal. Each two-axis receiver antenna is configured such that a first axis of the two-axis antenna is configured to detect a respective LF field transmitted by one of the LF antennas and a second axis of the two-axis antenna is configured to detect a respective LF field transmitted by another of the LF antennas.

A smart entry system for a vehicle having a lockable trunk is provided. The smart entry system includes portable devices, an onboard transmitter for transmitting request signals to the portable devices, an onboard receiver for receiving identification signals from the portable devices, and a trunk lockout protection feature. The trunk lockout protection feature is configured to receive a command signal to either initiate a trunk lockout protection sequence to unlock the trunk in the event that one of the portable devices is locked in the trunk or to disable the trunk lockout protection sequence to permit the trunk to remain in a locked state in the event that one of the portable devices is locked in the trunk.

An entry system for a vehicle includes a fob, a transmitter on the vehicle, a receiver on the vehicle, a control unit on the vehicle, and a vehicle lock in communication with the control unit. The fob is configured to transmit fob signals and to receive vehicle signals. The transmitter is for transmitting the vehicle signals to the fob. The receiver is for receiving the fob signals from the fob. The control unit is in communication with the transmitter and the receiver. The control unit is configured to determine whether the fob is getting closer to or farther from the vehicle based on the fob signals received by the receiver. The vehicle lock locks or unlocks in response to the control unit determining that the fob is getting closer to or farther from the vehicle and that the fob is not located in a hysteresis zone, which is disposed between a proximal zone, which is closer to the vehicle, and an outer zone, which is farther from the vehicle.

A tire pressure monitoring system includes tire sensors mounted in, on or adjacent respective tires of the vehicle, LF antennas mounted on the vehicle, and an ECU. Each tire sensor is configured to transmit an RF signal and to detect an LF field. Each antenna is configured to transmit an LF field to wake up the tire sensors. The ECU is in communication with the antenna, the tire sensors and a radio configured to receive AM broadcast signals. The ECU can communicate with the radio to inhibit speakers in communication with the radio from emitting sound while each LF field to wake up the tire sensors is being transmitted.
摘要:
A vehicle system includes a plurality of tire sensors, a plurality of low frequency (“LF”) antennas and an ECU. Each tire sensor is mounted in a respective tire of the vehicle. Each LF antenna is mounted on the vehicle and is configured to transmit an LF field to wake up two tire sensors. The ECU is in communication with the tire sensors, via a receiver, and the LF antennas. The ECU is configured to receive identification signals from the respective tire sensors and to determine locations of the respective tire sensors based on which antenna woke up the tire sensor transmitting the respective identification signal and whether the respective identification signal matches other received identification signals. The ECU is further configured to store the identification signals in the memory with the identification signals being associated with the respective tire sensors that transmitted the identification signal.

A wireless unit for a wireless vehicle system includes a receiver for receiving a vehicle-originating signal, a transmitter for transmitting a reply signal, a received signal strength indicator (RSSI) for determining a received signal strength of the vehicle-originating signal, a memory for storing sensitivity data, and a control unit in electrical communication with the receiver, the transmitter, the RSSI and the memory. The receiver has a sensitivity, and the memory is for storing sensitivity data corresponding to the sensitivity of the receiver. The control unit is configured to communicate with the transmitter to direct the transmitter to transmit the reply signal. The reply signal includes received signal strength data used for determining a distance between the wireless unit and an associated vehicle-side transmitter on an associated vehicle. The received signal strength data is based on the received signal strength and the sensitivity data.

A vehicle entry/tire pressure management system includes a plurality of tire sensors, a plurality of low frequency (“LF”) antennas and an ECU. Each tire sensor is mounted in a respective tire of the vehicle. Each LF antenna is mounted on the vehicle and is configured to transmit an LF field to wake up two tire sensors. Some antennas can also be configured to transmit a SMART entry LF search field to wake up a portable transmission/reception unit for keyless entry of the vehicle. The ECU is in communication with the tire sensors, via a receiver, and the LF antennas. The ECU is configured to receive identification signals from the respective tire sensors and to determine locations of the respective tire sensors based on which antenna woke up the tire sensor transmitting the respective identification signal and whether the respective identification signal matches other received identification signals.

A slide actuated key fob includes a housing having a transmitter disposed therein and at least one slide actuated button disposed on the housing. The transmitter sends an actuating signal when the at least one slide actuated button is slidably moved in a first direction and subsequently depressed in a second direction.
