摘要： PROBLEM TO BE SOLVED: To provide a wheel information processing device accurately determining to which of an attached wheel and a non-attached wheel the one in which predetermined state amount is detected corresponds.
SOLUTION: An ECU100 mounted on a vehicle has an abnormal condition detecting portion 102, a temperature actual changing amount obtaining portion 106, a temperature changing amount estimating portion 108, a non-attached wheel distinguishing portion 110, and an alarm adjusting portion 112. The abnormal condition detecting portion 102 detects an abnormal condition such as the breakdown of the wheel. The non-attached wheel distinguishing portion 110 distinguishes the non-attached wheel on the basis of actual changing amount of tire inside air temperature of each wheel obtained by the temperature actual changing amount obtaining portion 106 and a changing amount estimating value of the tire inside air temperature of each wheel obtained by the temperature changing amount estimating portion 108, and determines to which wheel of the attached wheel and the non-attached wheel the wheel of the abnormal condition corresponds. The alarm adjusting portion 112 controls a type of the alarm in an alarm device 36 on the basis of a determined result in the non-attached wheel distinguishing portion 110.

摘要： PROBLEM TO BE SOLVED: To certainly detect a tire abnormal condition by using air temperature and pressure. SOLUTION: A temperature sensor and a pressure sensor are attached to a rim, thereby detecting the air temperature and pressure in the tire. Relations between the air temperature and the pressure in a stationary state wherein a tire is in a normal state are respectively obtained in a low temperature stationary state wherein a vehicle stops for not less than a predetermined stopping time period after turning on an ignition switch, and in a high temperature stationary state wherein a change gradient in the air temperature is generally constant after starting of travelling. During travelling of the vehicle, it is determined whether the pressure is outside of an upper limit line and a lower limit line on the basis of detected air temperature, pressure, and a relation between temperature and pressure. If the pressure is outside, a ratio of pressure increment to air temperature increment is compared with a predetermined ratio to obtain contents of the abnormal condition. Due to delay of temperature transmission from a tire main heating portion to a temperature sensor and the like, a detection value is low even when actual air temperature is suddenly raised. However, temperature rise is estimated by air pressure rise, thereby predicting the occurrence of burst and estimating the air leakage of the tire and the generation of bulges.

摘要翻译：要解决的问题：通过使用空气温度和压力来确定地检测轮胎异常状况。
解决方案：温度传感器和压力传感器连接到轮辋上，从而检测轮胎中的空气温度和压力。在轮胎处于正常状态的静止状态下的空气温度和压力之间的关系分别在其中车辆在点火开关接通之后停止不少于预定停止时间的低温静止状态，以及在高温静止状态下，其中空气温度的变化梯度在行驶开始后通常是恒定的。在车辆行驶期间，基于检测到的空气温度，压力以及温度和压力之间的关系来确定压力是否在上限线和下限线之外。如果压力在外部，则将压力增量与空气温度增量的比率与预定比例进行比较，以获得异常状态的内容。由于从轮胎主加热部到温度传感器等的温度传递延迟，即使实际空气温度突然升高，检测值也低。然而，通过空气压力上升来估计温度上升，从而预测突发的发生和估计轮胎的空气泄漏以及产生凸起。版权所有（C）2005，JPO＆NCIPI
