基于英飞凌模块的汽车轮胎智能监测系统设计实现

Design of the Infineon module-based tire pressure monitoring system

汽车轮胎智能监测系统主要用于在汽车行驶时实时的对轮胎参数进行自动监测,对轮胎参数异常进行报警,以保障行车安全,是驾车者、乘车人的生命安全保障预警系统。该文基于英飞凌SP30模块及其开发系统的基础上,给出了主要电路设计和软件设计,实现汽车轮胎气压和温度的实时监测,并通过声光报警进行故障预警。

The tire pressure monitoring system（TPMS）is mainly used to automatic monitoring for the tire parameters to avoid accident.By using Infineon SP30 module,this paper develops main circuits design and software design based on the Infineon development system.In this product,the practical temperature and pressure inside each tire of the vehicle can be immediately and real time measured and the defective tire will be located by audio and visual LCD flashing alarm.
