摘要： A road-surface-condition estimation device is configured by a tire-side device and a vehicle-side device so as to grasp a road surface condition based on road surface condition data transmitted from a tire-side device. As a result, the road surface condition or a road surface μ of a traveling road surface of a vehicle can be accurately detected, and a more accurate lane keeping control can be performed according to the detection result. In particular, since the tire-side device estimates the road surface condition by detecting the vibration of a ground contact surface of the tire, the road surface condition can be estimated more accurately. Therefore, the more accurate lane keeping control can be performed.

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： 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： In order to detect a road surface condition, a road surface condition estimation device extracts a detection signal of a portion that detects vibration in a tire tangential direction in a vibration detection and power generation unit which is in a ground contact section, for example, a vibration power generation element. In this case, it is identified that the vibration detection and power generation unit is in the ground contact section, based on whether a centrifugal force acting on the vibration detection and power generation unit is generated, or not, and it is identified that a time when no centrifugal force is generated is in the ground contact section. As a result, even if a pulse level of an output voltage of the vibration detection generation unit changes according to a traveling speed of the vehicle, the ground contact section can be accurately identified.

摘要： A road surface condition estimation device extracts a detection signal of a vibration power generation element during a ground contact section to detect a road surface condition. A threshold used for determination of the ground contact section is variable according to a traveling speed of a vehicle. As a result, even if a pulse level of an output voltage of the vibration power generation element changes according to the traveling speed of the vehicle, the threshold corresponding to the change can be set. The ground contact section is determined with the use of the above thresholds, thereby being capable of performing the determination with high accuracy. Therefore, the road surface condition can be detected with high accuracy based on the ground contact section determined with high accuracy.

摘要： A vehicular power line communication system includes a master and a slave. The master uses a pair of twisted wires, whose far ends are connected to each other to be loop-shaped, as a power line and a communication line. The master thereby outputs high-frequency signals via the pair of twisted wires, transmitting an electric power and data modulation signals. The slave includes an aperture antenna being loop-shaped to receive data modulation signals using an electromagnetic induction connection in an electromagnetic field generated in the pair of twisted wires in response to an energization current of the pair of twisted wires. The slave further includes an error rate monitor circuit which monitors an error rate of data which are obtained from demodulation of the data modulation signals received via the aperture antenna.
