摘要： A tire device includes a vibration power generating element, a signal processing unit, and a transmitter. The vibration power generating element is arranged inside a tire and outputs a voltage corresponding to a time variation of a vibration generated in a tread of the tire. The signal processing unit is disposed inside the tire and performs signal processing on the voltage outputted from the vibration power generating element. The transmitter is arranged inside the tire and sends data subjected to the signal processing in the signal processing unit to a device provided outside the tire. The signal processing unit and the transmitter are driven by power generated in the vibration power generating element.

摘要： In a vehicular control device, an operating intention detection unit is disposed on a tire or wheel rim of a vehicle to detect an operating intention of a user relative to an opening/closing body of the vehicle. An operating intention acquisition unit is disposed on the vehicle body of the vehicle to acquire the operating intention. An ID code acquisition unit acquires, from a mobile device carried by the user, an ID code that identifies the user or the mobile device. An ID code determination unit determines whether the ID code is correct. The condition establishment determination unit determines, based on the operating intention of the user and on the result of ID code determination, whether an output condition for outputting operating instruction information that designates an operation of the opening/closing body is established. An output unit outputs the operating instruction information when the output conditions are established.

摘要： A first communication apparatus and a second communication apparatus are capable of wireless communication with each other. The first communication apparatus has a normal operation mode and a tuning mode that differs from the normal operation mode and allows a variable matching portion to adjust a matching state. When the tuning mode is selected, the first transmission portion transmits an operation mode transition request signal to the second communication apparatus. A first reception portion receives a tuning reference signal transmitted from the second communication apparatus in response to the operation mode transition request signal. A reception signal intensity measurement portion measures a reception signal intensity of the received tuning reference signal. The variable matching portion adjusts a matching state based on the measured reception signal intensity of the tuning reference signal.

摘要： An erroneous start is controlled based on vibrations of a tire, irrespective of a poor visibility or an algorithm of an image processing. A tire-side unit detects a vibration of a tire when the tire has collided with a wheel stop or the like, and outputs collision data to a vehicle-side unit. The vehicle-side unit determines an erroneous start of the vehicle. Therefore, the erroneous start of the vehicle can be controlled without being affected by the poor visibility or the algorithm of the image processing as in a case of utilizing a camera or a radar.

摘要： Data representing a ground contact time of a tire is transmitted from a tire side device, and received by a vehicle side device to calculate the ground contact time of the tire, to thereby calculate a ground contact length of the tire at that time. In a situation where a tire air pressure may change such as a tire exchange, the ground contact length at that time is set as a reference ground contact length, and a determination reference value is set on the basis of the reference ground contact length. As a result, the relative determination reference value corresponding to the tire type can be set, and a variation of the reduction rate of the tire air pressure when it is determined that the tire air pressure is reduced can be reduced. As a result, the reduction in the tire air pressure can be detected with high precision regardless of the tire type.

摘要： In a terminal position estimation system, a terminal position estimation apparatus, or a terminal position estimation method, an electric wave is received by a reception antenna of a communication terminal and is transmitted from multiple transmission antennas. A communication terminal position is estimated based on a magnetic field strength of the electric wave. When the communication terminal position is estimated, a position satisfying an approximate expression is estimated as the communication terminal position. The approximate expression shows a magnetic field strength distribution and is expressed by two variables of a distance from the multiple transmission antennas to the communication terminal and an angle between an axial direction of the multiple transmission antennas and a direction in which the communication terminal is positioned.

摘要： A vehicle air conditioner includes a casing, a heater core that heats an air flow by heat exchange between the air flow and a heat medium, an electric heater that heats an air flow by an electric power, and a determiner that determines whether a temperature of the heat medium is equal to or lower than a predetermined temperature. When the determiner determines that the temperature of the heat medium is equal to or lower than the predetermined temperature, an air flow introduced into a casing is heated by the electric heater and flows toward the vehicle interior without passing through the heater core.

摘要： A road surface condition estimation device includes a tire side device and a vehicle side device. The tire side device includes a vibration detection unit outputting a detection signal indicating a tire vibration magnitude, a signal processing unit, and a transmitter. The signal processing unit extracts a ground contact duration during which a portion of the tread corresponding to an arrangement position of the vibration detection unit is in contact with a ground, calculates a high frequency component level of the detection signal detected during the ground contact duration, counts cumulative rotation number of the tire, and corrects the level of the high frequency component based on the cumulative rotation number of the tire. The transmitter transmits corrected level of the high frequency component as road surface condition data. The vehicle side device estimates a road surface condition of the travelling road based on the received road surface condition data.
