摘要： In a disc brake control system for a vehicle, a control unit determines that a brake disc is in a condition of a thermal inclination of brake disc, and further determines that the brake disc is restored from the thermal inclination. The control unit operates an actuator of a disc brake devices to push a brake pad to the brake disc, when it determines that the brake disc is restored from the thermal inclination. According to such operation, the brake pad is moved to its normal position to the brake disc, so that a brake drag of the brake pad to the brake disc is suppressed.

摘要： 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.

摘要： 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.

摘要： A signal processor comprises wheel speed-detecting means for detecting a wheel speed signal including vibrational components of a tire, extraction means for extracting a resonant frequency of the vibrational components of the tire or a tire spring constant based on the wheel speed signals, air pressure-estimating means for estimating a tire air pressure based on the resonant frequency or the tire spring constant, and determining means for determining whether the estimated tire air pressure is abnormal or not by comparing with a determination value. Further, correcting means corrects at least one of the determination value, the estimated tire air pressure, the resonant frequency and the tire spring constant in response to a tire temperature. A temperature-sensing device is mounted inside the signal processor to detect a temperature associated with the tire temperature.

摘要： To achieve both accuracy in correcting sensing error caused by nonstandard factors of a pulse signal generated by rotation of a rotor to be measured and reduction in cost of an apparatus for doing the same, each passage of rotor sensors which rotate integrally with vehicle tires are sensed to produce pulse signals. The pulse signal periods are sequentially integrated every pulse signal train consisting of multiple pulse signals. When all of the pulse signal periods of the pulse signal train are integrated, the integrated value is stored in memory. The memory always stores the integrated values of the newest one rotation of the rotor to be measured. The pulse signal periods are averaged from the sum of the integrated values. With such a construction, the average of the pulse signal periods can be obtained as a learning reference value in the correction without storing all of the pulse signal periods of one rotation, thereby realizing both correction accuracy and cost reduction.

摘要： A wheel position identification apparatus includes: braking force fluctuation generating means controlling the braking force-applying means to generate a braking force fluctuation of the wheel independently. The apparatus further includes response probability obtaining means for obtaining a presence, or an absence, of a response of the wheel relative to the braking force fluctuation based upon a wheel rotational speed fluctuation of the wheel. The wheel rotational speed fluctuation is obtained from a rotation state sensor mounted on each wheel. The apparatus still further includes associating means for associating the wheel with the braking force-applying means respectively. The association is based upon a combination of a presence, or an absence, of the braking force fluctuation at each braking force-applying means and the presence, or the absence, of the response obtained by the response probability obtaining means.
