摘要： PROBLEM TO BE SOLVED: To detect a tire air pressure drop accurately by eliminating an influence of a slip of a driving wheel and eliminating an influence of a tread lift. SOLUTION: A wheel speed deviation value D computed according to a vehicle speed is sequentially corrected to produce a wheel speed deviation value D' presumed if an influence of a tread lift is eliminated. On the basis of the wheel speed deviation value D' for every short time from which the tread lift influence is eliminated, a regression line representing a relation between the wheel speed deviation value D' and a front-to-rear wheel speed ratio β is computed, and from the regression line, a corrected wheel speed deviation value D"AVE from which an influence of slips of the driving wheels 1c and 1d is eliminated is computed. On the basis of the corrected wheel speed deviation value D"AVE thus computed, a tire air pressure drop is detected.

摘要： PROBLEM TO BE SOLVED: To improve the detection accuracy of tire air pressure by accurately correcting an influence of a tread lift. SOLUTION: Tread lift correction is not executed until a differential pressure decision value ΔD'AVE exceeds a given threshold value Cth, and is executed upon such an excess. Specifically, the differential pressure decision value is corrected only if a tread lift has a truly great influence and correction is necessary, which can prevent dispersion in the differential pressure decision value caused by correction despite a minor tread lift influence. The differential pressure decision value is, however, corrected accurately under a great tread lift influence, so that an accurate differential pressure decision value can be computed and that degradation in detection accuracy of tire air pressure can be prevented.

摘要： PROBLEM TO BE SOLVED: To accurately compute a rotational state value in an ideal travel state by correcting overcompensation for a drop in air pressure of a driving wheel. SOLUTION: An average value D'AVE of wheel speed deviation values D and an average value βAVE of front-to-rear wheel speed ratios β are regressively computed to derive a regression line. An ideal state value βid is computed, which corresponds to a front-to-rear wheel speed ratio β in an ideal travel state with no slips. A point of intersection with a line of βid=F(A) representing the ideal state value βid is taken as a corrected wheel speed deviation value D'AVE.

摘要： PROBLEM TO BE SOLVED: To detect a tire air pressure drop accurately even under an influence of a tread lift. SOLUTION: An air pressure drop rate is computed from a variation in a corrected wheel speed deviation value D'AVE per unit time, and from the air pressure drop rate, a warning prediction time when the wheel speed deviation value D'AVE will be across a warning threshold level is computed. When the warning prediction time is reached, a tire air pressure drop is detected irrespective of an actual wheel speed deviation value D'AVE. In the course of the drop in air pressure, even if a vehicle speed is increased and a tread lift influences the corrected wheel speed deviation value D'AVE to change to a side causing no tire air pressure drop, the tire air pressure drop can be detected accurately when it is the warning prediction time.

摘要： PROBLEM TO BE SOLVED: To provide an electronic control type fuel injection device for an internal combustion engine to prevent leakage between a fuel injection valve and a fuel distribution piping, improve the assembling ability of an engine, and suppress the generation of working noise of the injection valve to a low value. SOLUTION: A mounting hole 24 through which a fuel injection valve 5 is mounted vertically to a fuel passage 23 in a fuel distribution piping, and the housing yoke 25 of a fuel injection valve 5 to contain an electromagnetic coil being a working noise generating source is inserted in the mounting hole 24. Since the fuel injection valve 5 and a fuel distribution piping are integrally coupled together, a leakage of fuel through a fuel passage 23 does not occur and a space in an engine is ensured, whereby, the assembling ability of the engine is improved. Further, since an injection nozzle hole position is situated in the vicinity of the intake valve of the engine, an amount of fuel wet in an intake pipe is reduced, and the power performance of an engine is improved. Further, since an electromagnetic coil is located in the fuel distribution pipe, working noise is not propagated to the outside.

摘要： PROBLEM TO BE SOLVED: To accurately determine that a vehicle is in a straightly advancing condition, only from wheel speed data under any travelling condition. SOLUTION: A wheel speed ratio operating means 21 and a distance operating means 31 and a distance ratio operating means 32 operate right and left wheel speed ratios, an actual traveling distance, a straight line distance and the distance ratio of both distances respectively for every predetermined check point (CP) based on right and left wheel speed values operated by a wheel speed operating means 13 from the detected values of right and left wheel speed sensors 11, 12. A wheel speed ratio fluctuation range evaluating means 24 extracts CP's at those points of time when the fluctuation range of the wheel speed ratio is comparatively small as an effective CP, and a determining means 43 determines that the effective CP whereby the distance ratio becomes minimum is the one at which the vehicle is in the straightly advancing condition among other effective CP's.

摘要： PROBLEM TO BE SOLVED: To improve detection frequency and improve detection accuracy by sampling a predetermined frequency component from an oscillation frequency of a wheel speed and sampling a frequency component of a frequency range used for inflation pressure detection, and selecting a wheel revolution speed based on gain ratio such as deflection. SOLUTION: Pickup coils 14a through 14d fixed to rotation axles of tires 10a through 10d are connected to an ECU 16 The ECU 16 calculates a wheel speed from outputted alternating current signals, sampling oscillation frequency component thereof, performs frequency analysis (FFT), and calculates an overall gain. Next, calculation of gain in a frequency range used for inflation pressure detection is performed based on a result of FFT calculation, a gain ratio between the overall gain and the frequency range used for the inflation pressure detection is calculated, and it is determined whether the gain ratio is in an appropriate range. Even if the overall gain is small, as long as gain of the sampled frequency component is suitable for detection, this value is used for detection, increasing a detection frequency thereby.
