    • Provided is a tire air pressure monitoring device capable of accurately determining the wheel position of a transmitter. The tire air pressure monitoring device comprises: a transmitter installed on each wheel for transmitting detected air pressure information via a wireless signal; a rotational position detection mechanism disposed on the vehicle body side which detects the rotational position of each wheel and also outputs rotational position information to a communications line at prescribed time intervals; and a vehicle body side rotation position estimation mechanism that estimates the rotational position (i.e., number of teeth) at the time of transmission by the transmitters, on the basis of the reception information for the wireless signal from the transmitters and the rotation position information for the wheels input via the communications line.
    • 提供能够精确地确定发射机的车轮位置的轮胎气压监视装置。 轮胎气压监测装置包括:安装在每个车轮上的发射器,用于经由无线信号发送检测到的气压信息; 设置在车身侧的旋转位置检测机构,其检测各车轮的旋转位置,并且还以规定的时间间隔向通信线路输出旋转位置信息; 以及车身侧旋转位置估计机构,其基于来自发送器的无线信号的接收信息和所述发送机的旋转位置信息来估计发送器发送时的旋转位置(即,齿数),以及 车轮通过通讯线路输入。

    • A tire air pressure monitor device is provided for monitoring air pressure in tires using pressure sensors, which are installed in the tire of each wheel. Each wheel has a transmitter for wirelessly transmitting the air pressure information along with a sensor ID when the wheel is at a predetermined rotation position. A vehicle body has a receiver for receiving the wireless signals. A wheel speed sensor is provided on a vehicle body for each wheel to determine the wheel rotation position. A TPMS control unit acquires the wheels rotation position when a wireless signal containing a certain sensor ID is transmitted. The TPMS control unit accumulates wheel rotation position data, and determines the wheel position corresponding to the wheel rotation position data having the smallest degree of dispersion from among the wheel rotation position data as the wheel position for the transmitter corresponding to the sensor ID.
    • 提供一种轮胎空气压力监测装置,用于使用安装在每个轮胎的轮胎中的压力传感器监测轮胎中的空气压力。 当车轮处于预定旋转位置时,每个车轮具有用于将空气压力信息与传感器ID无线传输的发射器。 车体具有用于接收无线信号的接收器。 在每个车轮的车体上设置有车轮速度传感器以确定车轮旋转位置。 当发送包含特定传感器ID的无线信号时,TPMS控制单元获取车轮旋转位置。 TPMS控制单元累积车轮旋转位置数据,并且从车轮旋转位置数据中确定与具有最小分散度的车轮旋转位置数据相对应的车轮位置,作为与传感器ID相对应的发送器的车轮位置。
