Abstract: PROBLEM TO BE SOLVED: To automatically register information corresponding to wheel identification information in vehicle-body-side device, in a wheel state acquisition device in which a wheel state is acquired by communication between a wheel-side device and the vehicle-body-side device. SOLUTION: Antennas 75, 76 for outputting trigger signals are mounted on a wheel mounting state inspection device. In a case where the wheel mounting state inspection device 14 faces a wheel, when the wheel is rotated, the wheel-side device 100 faces either of the antennas 75, 76, so that the identification information are transmitted from the wheel-side device by the trigger signals transmitted from the antennas 75, 76. The transmitted identification information are received and registered by the vehicle-body-side device 102. Thus, a worker can eliminate the need for transportation of a trigger device for each wheel and can automatically register the identification information. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To automatically determine whether the tire information is transmitted from a non-mounted tire or not when the tire information is transmitted from a plurality of tires including a mounted tire mounted on a vehicle and a non- mounted tire carried on the vehicle without being mounted on the vehicle. SOLUTION: A temperature of the mounted tire is raised with a large gradient as the vehicle traveling time passes, while the temperature variation of the non-mounted tire is small. When temperature variation quantity ΔTh in a predetermined time period shown by the temperature information included in the tire information transmitted from the tire is equal to or lower than predetermined variation quantity ΔTs, it is determined that the tire information is transmitted from the non-mounted tire.

Abstract: PROBLEM TO BE SOLVED: To provide a tire pressure warning system by which safety is further improved. SOLUTION: A tire pressure warning system emits a tire pressure decrease warning, based on a relationship between tire temperature and reference tire pressure, if the tire pressure is lower than a first tire pressure warning threshold value with respect to the reference tire pressure, and after emitting the tire pressure decrease warning, terminates the tire pressure decrease warning if the tire pressure is higher than a second tire pressure warning threshold value with respect to the reference tire pressure. In this system, the first tire pressure warning threshold value is lower than the second tire pressure warning threshold value, and a difference between the first tire pressure warning threshold value and the second tire pressure warning threshold one is structured to be smaller in case that the tire temperature is higher than a predetermined temperature threshold value than in case that the tire temperature is lower than the predetermined temperature threshold value.

Abstract: PROBLEM TO BE SOLVED: To enhance the durability of a rotary seal in an air pressure feeding device for feeding air pressure to a tire. SOLUTION: Pressure is applied to the rotary seal during the feeding of air pressure, and pressed to a non-rotation body and a rotation body by a large force. When a wheel is rotated in this state, the rotary seal is slid, a temperature is raised, and the durability of the rotary seal is deteriorated. Therefore, when the air pressure is fed, when a rotation speed of the wheel is lower than a first set speed (determination of S24 is YES), the air pressure is successively fed (S25). However, when it is not lower than the first set speed (determination of S24 is NO), it is intermittently fed (S26). As a result, the temperature rise of the rotary seal is suppressed and the deteriorated of durability can be suppressed. COPYRIGHT: (C)2009,JPO&INPIT
Abstract translation: 要解决的问题：为了提高空气压力供给装置中的旋转密封件的耐久性，用于向轮胎供给空气压力。
解决方案：在送风过程中，压力被施加到旋转密封件上，并通过大的力将其压向非旋转体和旋转体。 当轮在这种状态下旋转时，旋转密封件滑动，温度升高，并且旋转密封件的耐久性劣化。 因此，当供给空气压力时，当车轮的转速低于第一设定速度（S24的判定为“是”）时，连续供给气压（S25）。 然而，当不低于第一设定速度（S24的确定为否）时，间歇地进给（S26）。 结果，旋转密封件的温度上升被抑制并且可以抑制耐久性的劣化。 版权所有（C）2009，JPO＆INPIT

Abstract: PROBLEM TO BE SOLVED: To feed the identifying information from a wheel side device certainly to a body side device by improving a trigger device. SOLUTION: If a trigger signal transmitted from another trigger device installed in the set region is received when a transmission instructing switch 106 is turned On, existence of a risk of electric wave interference is given to a notification part (S61). In this case, no trigger signal will be supplied. If the identifying signal given after transmitting the trigger signal corresponds to the identifying signal stored in a memory, the count value is left as it is (Yes at S55). The wheel side device having fed the trigger signal is the one which transmitted identifying signal before, and it is known that the trigger signal is not received by the desired wheel side device. The operator can feed trigger signal again, for example upon changing the relative position. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To acquire fitted tire information and non-fitted tire information separately, not requiring a special operation by a driver and causing no vehicular vibration. SOLUTION: A transmission change program S1 stored in each tire side transceiver of a fitted and non-fitted tires is used to detect whether or not a specified signal from a specified signal transmitter is received by the tire side transceiver. When the judgement is YES, the specified signal is judged as the non-fitted tire to set the nonfitted tire judgement information to '10'. When the specified signal is not received and the output value of a vibration sensor 33 is smaller than a set value, the tire has a high possibility of the non- fitted tire, and the non-fitted tire judgement information is set to '01'. Then, the transmission contents of the tire information based on the tire condition detected by various sensors are changed at S6, and is transmitted to the vehicle side receiver. The transmission change at S6 includes a tire information change, a tire information reduction and transmission interval change. The vehicular side receiver discriminates the fitted tire from the non-fitted tire based on the transmitted tire information to apply a different treatment. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To detect a position of a wheel based on a receiving condition of tire information by a receiving device when the tire information transmitted from a transmitting device on a wheel side is received by the receiving device on a vehicle side and the tire condition is detected. SOLUTION: A plurality of receiving antennas 80 to 88 are provided so that the respective antennas direct to a direction of the tire information transmitted from the respective wheels. When the maximum receiving antenna is specified among reception intensity of the tire information of respective receiving antennas 80 to 88, the tire information is transmitted from the wheel in correspondence with the specified receiving antenna. Thus, the position of the respective wheels can be obtained without providing the receiving antennas 80 to 88 on a position adjacent to the respective wheels of the vehicle body.
