  • Patent number: 6879938
    Abstract: A tire burst predicting device which can predict occurrence of bursting of a tire and gives an alarm properly is provided. A break point frequency is estimated on the basis of time series data of wheel speed detected at a wheel speed sensor from frequency response of a first order model to which a transmission characteristic from a road surface disturbance to a wheel speed is approximated. A braking force gradient corresponding to the estimated break point frequency is estimated, on the basis of a map, which is prestored, representing a relationship between break point frequencies and braking force gradients. Extra high frequency components are eliminated from the estimated braking force gradient by a low pass filter to reduce estimation dispersion. Differentiators detect changing speed of the braking force gradient. An alarm is given when there is a possibility of bursting of tire when the detected changing speed reaches or exceeds a predetermined threshold value.

  • Patent number: 6450020
    Abstract: In a tire air pressure warning device, an outside impact such as hydraulic brake pressure is intentionally applied in a pulsating way to a tire when the vehicle substantially stops so as to exert vibration (rotation variation) of the tire axle. Through data processes in analyzing signals of wheel speed sensors that reflect the rotation variation of the tire axle, tire air pressure is estimated for informing to a driver abnormal tire air pressure.

  • Patent number: 6385553
    Abstract: In a tire air pressure estimating apparatus, wheel speeds of respective wheels are successively calculated when a vehicle is running. At least one of a tire resonance frequency and a tire spring constant is extracted from vibration frequency components included in a wheel speed signal with respect to each of tires. Tire air pressures of drive wheels are estimated based on the extracted tire resonance frequencies or the tire spring constants. Rotational state values (e.g. wheel speed values) of driven wheel tires are calculated based on the detected wheel speeds. Tire air pressures of driven wheels are estimated based on a deviation of the rotational state values of the driven wheel tires.

  • Patent number: 5826207
    Abstract: In a tire air pressure estimation based upon vibration components extracted rom a vehicle wheel speed signal, when the vehicle is a driven vehicle wheel, the precision of estimation is improved by canceling the components of vibration due to the resonance of the drive system from the vibration components based upon which the estimation calculation is made. The vibration components due to the resonance of the drive system can be canceled by canceling those vibration components extracted from the vehicle wheel speed signal which are the same in the phase between left and right driven vehicle wheels. When the tire air pressure of one of a pair of left and right driven vehicle wheels is lower than that of the other, the lower tire air pressure is more correctly estimated. Therefore, the higher tire air pressure may be estimated according to the lower tire air pressure against the drive system resonance.

  • Patent number: 5606122
    Abstract: Pickup coils which generate vehicle wheel speed signals which include vibration frequency components of tires during vehicle cruising are provided. An electronic control unit extracts resonance frequencies of tires from the vehicle wheel speed signals and estimates tire pneumatic pressure based on the extracted resonance frequencies. When an estimated vehicle wheel pneumatic pressure falls below a predetermined critical pneumatic pressure, pneumatic pressure decline warnings are generated and displayed by a display unit. An update switch is provided and when this update switch is turned on when replacing tires, the electronic control unit adjusts and sets the value of the critical pneumatic pressure described above based on the resonance frequency extracted during this time.

  • Patent number: 5557552
    Abstract: An absolute vehicle speed determining system is provided. This system includes generally a first sensor for detecting an unsprung vibration frequency component acting on a front wheel and a second sensor for detecting an unsprung vibration frequency component acting on a rear wheel. A phase difference between the unsprung vibration frequency components is found to project an absolute speed of a vehicle based on the phase difference and a wheel base of the vehicle. In addition, a tire condition monitoring system is provided which is designed to monitor properties of the tire, for example, the inflation pressure, the type of tire, or the amount of tire wear using the absolute speed of the vehicle projected.

Abutting walls are formed on the inside of the slit so as to receive the end of the film trailer, and transmit the rotation of the spool to the roll of film. The film trailer anchored on the spool core is guided by a guide portion on the spool core to be wound smoothly in contact with the surface of the spool core. In a preferred embodiment, the spool consists of two spool pieces. A shaft portion of the external spool piece is inserted in that of the internal spool piece. The film trailer is inserted and anchored between the shaft portions which are fitted together.

  • Patent number: 5251841
    Abstract: A photographic film cassette has a spool with a photographic film wound in a roll thereon. When the spool is rotated in a film unwinding direction, a photographic film leader is caused to advance outward from a cassette shell. The spool is constituted of two spool pieces which are rotatably and slidably coupled together via a guide shaft formed on the spool piece and a sleeve formed on the other spool piece. Each spool piece has a flange and a core. A cam follower is formed on the guide shaft and a cam groove is formed in the sleeve to receive the cam follower. The spool is thereby lengthened and shortened when the spool pieces are rotated relative to each other. Accordingly, when the spool is rotated, the flanges tightly clamp the photographic film roll laterally. The cam groove is formed so as to be closed to a core end which is coupled to the other core.
