摘要： A wheel position detecting device can suppress an erroneous detection of a wheel position even if a moving direction of a vehicle cannot be determined by wheel speed sensors whether in a forward direction or in a rearward direction. When an edge number (or a tooth number) is incremented based on detection signals of the wheel speed sensors of one, two or three wheels while the vehicle is at a halt, the edge number (or the tooth number) is not used as learning data. Thus, it is less likely that the wheel position is erroneously detected based on erroneous learning data. Therefore, even if the moving direction of the vehicle cannot be determined whether in the forward direction or the rearward direction by the wheel speed sensors, the wheel position detecting device can suppress the erroneous wheel position detection.

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.

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 attached to a back surface of a tire tread and 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, and calculates a high frequency component level of the detection signal detected during the ground contact duration as road surface condition data. When the ground contact duration is ended, a transmission trigger is transmitted to the transmitter and the transmitter transmits the road surface condition data. The vehicle side device estimates a road surface condition of the travelling road based on the road surface condition data.

摘要： A tire system includes a tire side device that is arranged corresponding to a tire provided in a vehicle and transmits data related to the tire, and a wear estimation unit that estimates a tire wear state based on the data related to the tire. The tire side device holds data related to an elapsed time since the tire was manufactured as data related to the tire, transmits data related to the elapsed time to the wear estimation unit. The wear estimation unit estimates the tire wear state based on the mileage from the start of use of the tire and a tire deterioration degree indicated by the data related to the elapsed time.
