摘要： PROBLEM TO BE SOLVED: To provide a device for determining with a new method that a vehicle is traveling. SOLUTION: A radio receiver specifies a change of the RSSI voltage linearly related to intensity of a radio signal during a reception period of the radio signal (120) based on reception of the radio signal from a radio transmitter mounted on a wheel of one's own vehicle (110), and determines that the one's own vehicle is travelling (140) based on the maximum amount of change exceeding a reference amount of change (130). The radio receiver compares a change of the RSSI voltage with the lapse of time during the reception period with the relation between the RSSI voltage and angle, and on the basis of the comparison, when a part similar to a change pattern of the RSSI voltage with the lapse of time exists in the relation between the RSSI voltage and angle (150), the radio receiver considers the angle width of that part as an angle of rotation of the wheel during the reception period, and specifies the travelling speed of the one's own vehicle based on that angle (160).

摘要： PROBLEM TO BE SOLVED: To receive data of a tire air pressure transmitted from a sensor transmitter on the receiver side without generating electric wave interference, even if an electric wave for power charge and an electric wave of the data transmitted from the sensor transmitter have the same frequency band. SOLUTION: The electric wave for power charge is transmitted from a car body side antenna as long as a Tmax time. Power charge is performed in the sensor transmitter by the electric wave for power charge, and a charge voltage of a charge part is heightened gradually. When the charge voltage of the charge part reaches a sensor driving start voltage, the sensor transmitter is started, and transmits the data of the tire air pressure after elapse of the Tmax time. Hereby, since transmission of the electric wave for power charge is stopped without fail when the data of the tire air pressure is transmitted by the sensor transmitter, interference between the electric wave for power charge and the electric wave transmitted from the sensor transmitter can be avoided.

摘要翻译：要解决的问题：即使接收侧的传感器发送器发送的轮胎气压的数据不产生电波干扰，即使电力充电的电波和从传感器发送的数据的电波发射机具有相同的频带。
解决方案：只要Tmax时间，电动汽车的电波就从车体侧天线发送。通过用于电力充电的电波在传感器发射器中进行功率充电，并且充电部分的充电电压逐渐升高。当充电部分的充电电压达到传感器驱动启动电压时，启动传感器发射器，并在经过Tmax时间之后发送轮胎空气压力的数据。因此，由于当传感器发送器传输轮胎空气压力的数据时，由于电力充电用电波的传输停止，所以可以避免电力充电用电波与传感器发送器发送的电波之间的干扰。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a tire air pressure detection device shortening a communication time by reduction of consumption power of a transmitter. SOLUTION: Dummy data indicating transmission of present data are transmitted before the present data including data regarding the tire air pressure, the dummy data are intermittently transmitted. An amount of power required for transmitting the dummy data is thereby reduced. As a result, an amount of power required when the data are transmitted from the transmitter 2 to a receiver 3 is reduced. In the tire air pressure detection device, therefore, the communication time is shortened by reduction of consumption power of the transmitter 2. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To detect which wheel is mounted with each transmitter without reading ID information by a user. SOLUTION: A first trigger machine 5a is arranged at different distances from both front wheels 6a and 6b, a second trigger machine 5b is arranged at different distances from both rear wheels 6c and 6d, and, when a first trigger command is received from first and second trigger machines 5a and 5b, a transmitter 2 reduces sensitivity of a receiving antenna 25. When a second trigger command is generated from first and second trigger machines 5a and 5b during the sensitivity reduction, because of the attenuation of the receiving selectivity of the second trigger command in the transmitter 2, the transmitter 2 mounted to the closer side wheel from the first and second trigger machines 5a and 5b can receive the second trigger command, and the transmitter 2 mounted to the far side wheel cannot receive the second trigger command. Thus, it can be specified which of the wheels 6a-6d each transmitter 2 is mounted to. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a wheel side antenna device capable to communicate in a wide range even if it is mounted in a space-limited place, and a tire condition detecting device having the antenna device. SOLUTION: This wheel side antenna device is installed to wheels 6a-6d, for communicating with a vehicle body 7 side. A plurality of antennas 24 constituted by winding a conducting wire 24b around a magnetic core 24a are provided, and a plurality of antennas 24 are connected in parallel. Thereby, unless the length of the magnetic core 24a is made large, a range capable to communicate with the vehicle body 7 side can be made wider than when a single antenna is provided. Also, when a plurality of antennas 24 are provided, the length of one antenna 24 can be made short, so that the device can be mounted in a narrow place. Thus, if the antenna 24 is mounted to the space-limited place, a wide range of communication is possible. COPYRIGHT: (C)2007,JPO&INPIT
