The problem of interfacing automotive body mounted electronics to sensor elements mounted on a vehicle's rotating wheels presents a serious challenge. The main requirement is to reliably pass continuous real time pressure, temperature and force vector data from sensors that are mounted inside a vehicle's rotating wheels to chassis mounted receiver electronics. This paper focuses an ETV's VisiTyre, a direct measurement Tyre Pressure Monitoring System (TPMS) incorporating sensor elements which are complete 'system on silicon' subsystems having a simple yet robust, directly connected, 2-wire interface and communication channel to chassis mounted receiver electronics. VisiTyre obviates the need for sensor batteries and RF transmitters inside the tyre and introduces the concept of standardised 'TPMS Enabled Tore Rims' and 'TPMS Enabled Wheel Hubs' that allows easy tyre and wheel removal, replacement and transparent wheel rotation using existing tyre industry equipment and facilities. The VisiTyre standard is proposed for adoption as an universal standard for direct connect tyre pressure measurement systems.
