The TPMS(tire pressure monitoring system)architecture, and WTPM(wireless tire pressure module)components are introduced. The power consumption composition of WTPM, including WTPM pressure measuring module, temperature measuring module, voltage measuring module, signal conditioning module, wireless transmission module, low frequency interface, static power, battery self-discharge, and impulse self-discharge is presented. Taking the WTPM based on the power consumption composition adopted by a famous domestic vehicle manufacturer as a typical example, the calculation and test are carried out. The calculation and test results show that the WTPM power is mainly consumed by the pressure measuring module, the static power, and the battery self-discharge. The presented WTPM power consumption composition and calculation method are reasonable and meet the requirements for vehicle application.
