中文摘要：
汽车制动失灵，即使在非高速状态下行驶也会影响生命安全。采用汽车轮胎内置传感器的事故防范技术正在兴起。文中通过轮胎内置MEMS电容加速度传感器来获取径向加速度，把制动时段的径向加速度信号向外传送，用作间接监测汽车制动性能的依据。文中提出了为解决制动起始点自动判定这个关键环节所采取的动态平滑去噪、斜率比较等实时处理方法，制动起始时刻自动判别的实验结果验证了该方法的可行性。
英文摘要：
Automobiles braking performance out of order would endanger human life even if in non - high speed driving. A great upsurge has been growing up in technique research of preventing against accidents in running automobiles We propose a scheme of using tire-mounted MEMS accelerometer to sense tire radial acceleration, the radial acceleration signals in braking period are sent to outer receiving system and used as a basis of ance monitoring indirectly. The signal processing method of braking performdynamic smoothing and slop comparing for detecting automatically the beginning time of braking operation are presented, the experiment testing has verified the autodetection method practicable.
