摘要： A method for localizing tire sensors includes determining a wake up field power, transmitting an LF wake up field having the wake up field power from an LF antenna on the vehicle, receiving an identification signal from each tire sensor awakened by the transmitted LF wake up field, and determining whether a desired number of tire sensors have woken up in response to the transmitted LF wake up field based on the received identification signals. When the desired number of tire sensors have woken up, the method can further include recording the identification signals received from the awakened tire sensors and the respective antennas that awoke the respective tire sensors. The method further includes determining whether a desired number of antennas have transmitted a respective LF wake up field. When the desired number of antennas have transmitted a respective LF wake up field, the method can further include comparing the received identification signals and determining locations for the tire sensors based on which respective antenna woke up which respective tire sensor and whether the received identification signals match other received identification signals.

摘要： In a wheel identifying apparatus, first and second devices respectively transmit first and second trigger signals. The first device is mounted on the body of a vehicle closer to the front axle than the rear axle and closer to one of the front wheels than the other; it has the same height as the front axle and an orientation angle in a range of 0 to 90°. The second device is mounted on the vehicle body closer to the rear axle than the front axle and closer to one of the rear wheels than the other; it has the same height as the rear axle and an orientation angle in a range of 0 to 90°. Consequently, the first trigger signal can be reliably received by transceivers on the front wheels, and the second trigger signal can be reliably received by transceivers on the rear wheels.

摘要： A tire parameter monitoring system has a plurality of sensor units for monitoring tire parameters, with each sensor unit mounted with a different vehicle tire. Each sensor unit has an RFID tag reader for interrogating an RFID tag securely mounted to the vehicle adjacent the corresponding tire and containing a unique identification code. Each sensor unit has a microcontroller for combining each RFID identification code with corresponding tire parameter signals, and a transmitter for transmitting the combined signals to a receiving location. Received tire parameter signals are correlated with the tire location using the RFID identification code, and driver advisory signals are presented to the driver by a display/alarm unit. Two alternative power supplies are provided. A first type uses a battery and a power management circuit for eliminating power drain when the RFID tag reader is energized. A second type uses inductive power to provide an inexhaustible power source.

摘要： Systems, methods, and apparatuses are provided for monitoring the status of sensors that sense the parameters of one or more vehicle components. A monitor in a first vehicle receives RF signals from sensors that are located remotely from the monitor. The sensors may be associated with vehicles other than the first vehicle, and it is desired to monitor only the sensor(s) that are also associated with the first vehicle. Sensors may be selected for monitoring by reading a plurality of different sensors and selecting one or more sensors from the plurality of sensors that are associated with the first vehicle and thus are to be monitored Sensors that are to be monitored are selected based on predetermined criteria after it is determined that the first vehicle is in motion. The monitor includes a motion sensor that is operable to determine if the vehicle is in motion.

摘要： The device and the method enable the localization of transponders, particularly in motor vehicles. A determination of the distance of different transponders from the base station is made possible by evaluating the different request signals and response signals received and also the physical variables contained therein, such as signal level, charging time, and signal propagation delay. As a result of the relative determination of the different distances of the transponders from a base station, it is for example possible to determine the position of wheels of a motor vehicle. This means savings in terms of tire electronics, which require a separate power supply and are technically more complicated and more expensive to use than transponders.

摘要： In a system for remote monitoring of vehicle tire pressure, a system and method for automatically identifying tire location. A tire pressure monitor mounted in each tire includes a sensor for sensing tire pressure, a transmitter for transmitting a signal representative of the sensed tire pressure, and a magnetic switch for actuating the transmitter. An electromagnets is mounted on the vehicle in proximity to each tire location and generates a magnetic field causing the magnetic switch to actuate the transmitter of the associated tire pressure monitor. A controller mounted on the vehicle is provided in communication with the electromagnets, processes the tire pressure signals from the transmitters, and conveys tire pressure and location information to a user. The controller energizes the electromagnets so that each received tire pressure signal is automatically associated with a specific tire location.
