    • A wheel position determination system and method to count wheel revolutions in a wheel unit of a tire monitoring system. An indication of the count is transmitted, optionally along with an indication of a left/right side position of the wheel on the vehicle, and an identification unique to the transmitting wheel unit, to a central controller of the tire monitoring system. In the central controller of the tire monitoring system, the count is compared with wheel speed information for the vehicle, such as from an ABS system, to determine if one wheel on each side of the vehicle is rotating at a different speed. Based at least in part upon a determination that each wheel speed is unique, a determination of wheel location may be made.
    • 轮胎位置确定系统和方法,用于对轮胎监控系统的车轮单元中的车轮转数进行计数。 发送计数的指示,可选地伴随着车辆上的车轮的左/右侧位置的指示,以及传送轮单元特有的标识,传送到轮胎监视系统的中央控制器。 在轮胎监视系统的中央控制器中,将计数与来自ABS系统的车辆的车轮速度信息进行比较,以确定车辆两侧的一个车轮是否以不同的速度旋转。 至少部分地基于确定每个车轮速度是唯一的,可以确定轮位置。

    • A TPM system wheel unit measures rotational period over a number of wheel revolutions, calculates a value of a period of the revolutions and wirelessly transmits the calculated value of the period to a tire pressure monitoring system receiver in the vehicle mounting the wheel. Alternatively, each wheel unit transmits an RF burst of a predetermined length and a received RF burst envelope modulated with a periodic modulation pattern is used to calculate the period of one wheel rotation for each wheel. A central vehicle electronic control unit monitors wheel speed signals for each wheel of the vehicle and calculates a period for the wheel speed signal for each wheel of the vehicle, bounded by a rolling window which may be of variable length. The calculated values are compared and the wheel unit and the wheel location are correlated therefrom.
    • TPM系统轮单元测量多个车轮转数的旋转周期,计算转数周期的值,并且将安装车轮的车辆中的轮胎压力监视系统接收器的周期的计算值无线发送。 或者,每个车轮单元发送预定长度的RF突发,并且使用用周期性调制模式调制的接收的RF突发包络来计算每个车轮的一个车轮旋转的周期。 中央车辆电子控制单元监视车辆的每个车轮的车轮速度信号,并且计算车辆的每个车轮的车轮速度信号的周期,该车轮速度信号由可能具有可变长度的滚动窗口所限定。 比较计算出的值,并将车轮单元和车轮位置相关联。
