确定滚动轮胎的接触印迹事件的持续时间的方法及TPMS部件
摘要：
示例提供了用于确定滚动轮胎的至少一个接触印迹事件的持续时间的方法、部件、轮胎安装式TPMS模块、TPMS系统和机器可读存储器或计算机程序。用于确定滚动轮胎的至少一个接触印迹事件的持续时间的方法，包括：从轮胎安装式加速度传感器获得滚动轮胎的加速度测量样本的序列；以及基于序列中的在当加速度测量样本越过第一阈值时的第一时间实例和当加速度测量样本越过第二阈值时的第二时间实例之间的加速度测量样本，来确定接触印迹事件的持续时间。
摘要（英）：

Examples provide a method, a component, a tire-mounted TPMS module, a TPMS system and a machine readable storage or computer program for determining a duration of at least one contact patch event of arolling tire. A method for determining a duration of at least one contact patch event of a rolling tire, comprises obtaining a sequence of acceleration measurement samples of the rolling tire from atire-mounted acceleration sensor,and determining the duration of the contact patch event based on acceleration measurement samples of the sequence between a first time instance when the acceleration measurement samples cross a first threshold and a second time instance when the acceleration measurement samples cross a second threshold.
