摘要

PPROBLEM TO BE SOLVED: To consistently detect the rotation of a tire unceasingly from a low-speed zone to a high-speed zone even when using an acceleration sensor of low accuracy. PSOLUTION: The normal acceleration measured value ASBi/SBis compared with the threshold THSB1/SBin the high-speed range for each cycle (SSB3/SB). In this comparison, when ASBi/SBTHSB1/SB, it is regarded that the tire is rotated (SSB3/SB→SSB4/SB). When ASBi/SBTHSB1/SB, the absolute value δASBi/SBof the difference between the normal acceleration measured value ASBi/SBand the normal acceleration measured value ASBi-1/SBin the previous cycle is compared with the threshold THSB2/SB(SSB6/SB). When δASBi/SBTHSB2/SB, it is regarded that the tire is rotated (SSB6/SB→SSB4/SB). When the timer performs the counting operation for a long time even if δASBi/SBTHSB2/SB, it is regarded that the tire is rotated. PCOPYRIGHT: (C)2009,JPO&INPIT

要解决的问题:即使使用低精度的加速度传感器,也要始终如一地检测轮胎从低速区域到高速区域的不断旋转。

解决方案:在每个周期的高速范围内,将正常加速度测量值A i 与阈值TH 1 (S 3 。在该比较中,当A i 1 时,认为轮胎旋转了(S 3 &rarr; S 4 )。当A i 1 时,法向加速度测量值A i <的绝对值ΔA i / SB>和上一周期的正常加速度测量值A i-1 与阈值TH 2 (S 6 )进行比较。当ΔA i 2 时,认为轮胎旋转了(S 6 &rarr; S 4 。即使ΔA i 2 ,计时器长时间进行计数操作,也认为轮胎旋转了。
