Design and implementation of TPMS tire air leakage alarm functionion based on the SP370

摘要

A tire pressure monitoring system TPMS was designed, while realized the real-time monitoring vehicle tire pressure, temperature, battery voltage and other functions. TPMS transmitting module uses the infineon triad integrated module SP370 design, to achieve detection information, and transmitting to the receiving module by the wireless transmission. The receiving module is to accept data and process of abnormal situation, and through the process of software to design the tyre gas leak detecting method.
