ABSTRACT:
A tire monitor system employs a single RF detector mounted on the vehicle. The tire monitor system also includes a control unit and a receiver. The single RF detector is positioned to be proximate a front axle or a rear axle. The RF detector also may be positioned off-center. The control unit 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 may further use a received signal strength and/or acceleration signals to determine position information of the tire monitors.
