摘要： Techniques are described for using one or more wireless host devices to perform tire localization of TPMS sensor data by determining received signal strength indicator (RSSI) signatures that are unique to the wireless communication channel between a host device and each TPMS sensor. RSSI signatures represents a periodic variation of the wireless communication channel between a host device on the car body and a TPMS sensor in a rotating tire. Characteristics of the communication channel is a function of the wheel angle and is periodic with wheel rotations. The RSSI signatures may be created by matching RSSI measurements of packets received by the host device from a TPMS sensor with wheel angles derived from wheel speed sensor (WSS) data of the anti-lock braking system (ABS). The RSSI signatures are a unique marker of each wheel that may be used to identify the locations of the TPMS sensors for tire localization.
