    摘要： A tire monitor system ( 100) employs a single RF detector ( 112) mounted on the vehicle. The tire monitor system (100) also includes a control unit ( 110) and a receiver ( 120). The single RF detector ( 112) is positioned to be proximate a front axle or a rear axle. The RF detector (112) also may be positioned off-center. The control unit (110) distinguishes front tire monitors from rear tire monitors by comparing a number of RF transmissions received by each tire monitor. The control unit also may distinguish between left tire monitors and right tire monitors by comparing the number of RF transmissions received by each tire monitor. In other embodiment, the tire monitor system (100) may further use a received signal strength and/or acceleration signals to determine position information of the tire monitors.

    摘要： A remote tire monitor system (102) includes a control unit (112) and a plurality of tire monitors (124, 126, 128, 130) mountable on respective wheels (104, 106, 108, 110) of a vehicle (100) to transmit radio signals to the control unit. The tire monitors each include a pair of motion sensors such as shock sensors (210, 212) and a control circuit (202) configured to determine position information for the respective tire monitor based on first and second shock sensor signals from the pair of shock sensors. The shock sensors produce an output voltage proportional to a change in applied force. Therefore, the offset created by centrifugal force in previously used accelerometers is absent, simplifying design of the tire monitors.
