    • A fuel efficiency degradation amount displaying device detects a tire air pressure and calculates an amount of degradation of fuel efficiency of the vehicle compared to fuel efficiency in a case that the tire air pressure is appropriate. Then the fuel efficiency degradation amount displaying device indicates not only a warning of the decrease of the tire air pressure but also the amount of the fuel efficiency degradation. Therefore the driver can recognize the amount of the degradation clearly and intuitively. As a result, it is possible to prevent drivability of the vehicle from getting worse, because the driver can adjust, knowing a relation between the tire air pressure and the fuel efficiency, the tire air pressure to the appropriate tire air pressure.
    • 在轮胎空气压力适当的情况下,燃料效率劣化量显示装置检测轮胎空气压力并计算与燃料效率相比的车辆的燃料效率的劣化量。 然后,燃料消耗率劣化量显示装置不仅指示轮胎空气压力的降低的警告,而且还指示燃料效率降低的量。 因此,驾驶员可以清楚和直观地识别退化的量。 结果,可以防止车辆的驾驶性能变差,这是因为驾驶员能够调整知道轮胎空气压力和燃料效率之间的关系,轮胎空气压力与适当的轮胎空气压力的关系。

    • A tire condition detecting device 1 and an attaching method thereof, and a tire condition monitoring system, capable of preventing the attenuation caused by tires and wheels, of radio waves transmitted from a transmission section more effectively than before, are provided. The tire condition detecting device comprises a case 3 having an insertion part 5 inserted into a hole 13 provided in a rim 12; and a sensor and transmission section 2 contained in a case main body 4. It is attached to the rim by inserting the insertion part 5 of the case into the hole of the rim from the inside of the rim so that the case main body is arranged inside the rim, that is, on a side of the rim 12 opposite to a side on which an air chamber 15 of a tire 14 is located.

    • A tire condition monitoring system for a vehicle has a chassis-side transmitter/receiver and a tire-side transmitter/receiver. The tire-side transmitter/receiver measures an interval between two successive request signals of the chassis-side transmitter and controls a time point of transmission of a response signal of the tire-side transmitter/receiver based on the measured interval so that the response signal is transmitted when the tire-side transmitter/receiver is in the communication range of the chassis-side transmitter/receiver. A control unit determines a time interval of one rotation of a tire based on a vehicle speed, and drives the chassis-side transmitter/receiver to transmit the request signal at an interval set to be shorter than an interval in which the tire rotates the communication range of the chassis-side transmitter/receiver.
    • 一种用于车辆的轮胎状况监测系统具有底盘侧发送器/接收器和轮胎侧发送器/接收器。 轮胎侧发送器/接收器测量机架侧发送器的两个连续请求信号之间的间隔,并且基于测量间隔控制轮胎侧发送器/接收器的响应信号的发送时间点,使得响应信号 在轮胎侧发送器/接收器处于机箱侧发送器/接收器的通信范围内时,发送。 控制单元基于车速确定轮胎一圈的时间间隔,并且驱动机架侧发送器/接收器以设定为短于轮胎旋转通信的间隔的间隔来发送请求信号 机箱侧发射机/接收机的范围。

    • In a data receiver, pulse edges are sequentially detected from the pulse string. If a pulse which has a width equal to two cycles of the reference clock signals is detected, bit data ‘1’ is restored. If two consecutive pulses each of which has a width equal to one cycle are detected, bit data ‘0’ is restored. If a pulse width between two consecutive pulse edges is not equal to one cycle or two cycles, it is presumed that a pulse edge of an erroneous pulse is detected. If the pulse width between the pulse edge, which is presumed to correspond to the erroneous pulse, and the next pulse edge is equal to or shorter than a predetermined threshold Th, the pulse edge and the next pulse edge is invalidated.
    • 在数据接收机中,从脉冲串顺序地检测脉冲边缘。 如果检测到具有等于参考时钟信号的两个周期的宽度的脉冲,则恢复位数据“1”。 如果检测到两个连续的脉冲,其宽度等于一个周期,则恢复位数据“0”。 如果两个连续的脉冲边沿之间的脉冲宽度不等于一个周期或两个周期,则假设检测到错误脉冲的脉冲边缘。 如果推定为对应于错误脉冲的脉冲边缘与下一个脉冲沿之间的脉冲宽度等于或小于预定阈值Th,则脉冲沿和下一个脉冲沿无效。
