摘要： A tire position determination system includes a position determination unit that determines a tire position by obtaining axle rotation information when each of tire pressure transmitters reaches a specific position on a tire rotation path of a corresponding tire and specifying a tire that rotates in synchronism with the axle rotation information of each axle. A cycle calculator calculates a rotation cycle of each axle based on the axle rotation information. A validity determination unit determines validity of accuracy of gravity sampling based on the rotation cycle, a gravity sampling interval time of a gravitational component acting on each tire pressure transmitter, and a gravity sampling frequency in the rotation cycle. The position determination unit determines the tire position based on a determination result of the validity determination unit.

摘要： A tire valve ID registration system includes tire valves arranged in tires and configured to each transmit a radio wave including a valve ID, and a receiver arranged in a vehicle and configured to receive the radio wave transmitted from each tire valve and register the valve ID. Each of the tire valves selectively executes one of radio wave transmission modes in accordance with whether the vehicle is in a traveling state or a still state. A mode estimation unit monitors whether the vehicle is in the traveling state or the still state and estimates the radio wave transmission mode of the tire valves. An ID registration unit determines that the valve IDs transmitted from the tire valves in one of the radio wave transmission modes estimated by the mode estimation unit are valve IDs of the vehicle and registers the determined valves ID to the receiver.

摘要： A tire position determination system includes a tire pressure detector attached to each tire to generate a tire pressure signal. An acceleration detector generates gravitational information for each tire pressure detector. A receiver arranged in a vehicle body receives the tire pressure signal from each tire pressure detector. An axle rotation amount detector detects an axle rotation amount of an axle corresponding to each tire and generates pulses indicative of the detected axle rotation amount. An automatic locator determines the position of each tire based on the gravitational force and the pulses. A pulse combination determination unit determines whether or not a combination of the pulses from the axle rotation amount detectors is appropriate. A pulse acquisition timing setting unit sets an acquisition timing of the pulse signal for the automatic locator based on the determination of the pulse combination determination unit.

摘要： A tire position determination system provided in a vehicle including a first tire and a second tire includes an initiator that transmits a command signal, a first detector attached to the first tire, a second detector attached to the second tire, and a monitoring unit. A distance between the first tire and the initiator is equal to or shorter than a distance between the second tire and the initiator. Each of the first detector and the second detector includes an acceleration sensor. A detection signal includes a detection value from the acceleration sensor. The monitoring unit performs determination processing for determining a position of the first tire and a position of the second tire based on positional relation between the detector and the initiator estimated from the detection value from the acceleration sensor.

摘要： A tire position registration system includes a receiver that estimates, from a data group of axle rotation information of each of axles obtained for each valve ID, a parent population of the axle rotation information of each of the axles. The receiver sets a synchronized wheel tolerance region, which functions as an index for determining validity of the corresponding axle rotation information, for each parent population based on a population mean that is a mean of the parent population. The receiver specifies the tire position by determining whether or not the axle rotation information obtained for each valve ID is included in the synchronized wheel tolerance region of the corresponding parent population and specifying the axle rotating in synchronization with the tire corresponding to the valve ID.
