摘要： An electric motor 10 and a reduction gear mechanism 11 are connected to each other by a flexible coupling 12, such as an Oldham's coupling, which is a power transmission mechanism. Also, a casing 11c of the reduction gear mechanism 11 is integrally structured together with a knuckle 5, which is an unsprung part of a vehicle, or mounted to the knuckle 5. Further, a motor case 10a of the electric motor 10 is mounted to a motor mounting member 4m provided on the lower part of a strut 4 for suspending the knuckle 5 through the medium of a shock absorbing mechanism 20 equipped with a spring member 21, a damper, and two guide members 23 for guiding the operating direction of the spring member 21 and the damper. An in-wheel motor system thus structured allows the mass of the motor 10 to act as the mass of a dynamic damper and thus features not only improved ground contact performance and riding comfort of a vehicle running on a rough road but also superior space efficiency.

摘要： Minute surface unevenness formed on the surface of an object under inspection is detected, thereby improving the accuracy of an appearance inspection. A target surface in the sidewall region (21) of a tire (20) is illuminated by a red slit light from a first illuminating means (11) disposed in the direction of 45 degrees with respect to the normal line to the target surface. At the same time, the target surface is illuminated by a blue slit light from a second illuminating means (12) disposed in the direction of −45 degrees with respect to the normal line. The illuminated surface is shot by a line camera (13) from the direction of the normal line. An R-component image and a B-component image are produced from the original image, and their respective luminance distribution waveforms are obtained. The surface unevenness formed on the target surface is detected on the basis of the luminance distribution waveforms.

摘要： A method, featuring robustness against changes in tire size, is provided for determining a road surface condition by dividing a time-series waveform of tire vibrations into windows without resorting to detection of the peak positions or measurement of the wheel speed. A time-series waveform of tire vibrations detected by a tire vibration detecting unit is windowed by a windowing unit. Time-series waveforms are extracted from the respective time windows, feature vectors X are calculated therefor, and then likelihoods Z for road-surface HMMs (hidden Markov models) are calculated. The likelihoods Z1 to Z5 calculated for the respective road-surface HMMs are compared with one another, and a road surface condition corresponding to the road-surface HMM showing the highest likelihood is determined to be the condition of the road surface on which the tire is running.

摘要： A simple method and apparatus for accurately estimating the contact patch shape of a moving tire. The vibration waveforms of a tire (20) with sipe rows (25A, 25B) formed at the respective pitches (Pa, Pb) in the left and right shoulder lands (24a, 24b) are detected by an acceleration sensor attached to a knuckle of the vehicle. Rotational order spectrums are obtained by performing a rotational order analysis on the vibration waveforms. The peak height (Za) of the rotational order (na) corresponding to the pitch (Pa) and the peak height (Zb) of the rotational order (nb) corresponding to the pitch (Pb) are extracted from the rotational order spectrums. The peak height (Za) is compared with the threshold value (Ka) to estimate whether the contact patch shape of the tire is longer than the contact patch length (La) of the tire contact patch shape (Fa) set as the use limit due to internal pressure drop or load increase, and the peak height (Zb) is compared with the threshold value (Kb) to estimate whether it is shorter than the contact patch length (Lb) of the tire contact patch shape (Fb) set as the use limit due to internal pressure rise or load decrease.

摘要： Provided is a tire contact state estimating method using a tire for estimating a contact state having a block row, in which a plurality of blocks having different lengths in a tire circumference direction are arrayed, and having a tread pattern, in which the kicking ends of two adjacent blocks of the block row are formed at a constant period. The method detects the periodic vibrations, which are generated when the kicking ends to be propagated from the tire to the knuckle leave the road surface sequentially, by an acceleration sensor attached to a knuckle. The method detects such a vibration level of the frequency waveform in a detection frequency band as is calculated from both a wheel speed and that period, to estimate the grounding state of the tire. Thus, without attaching any sensor to the tire, the grounding state of the running tire can be precisely estimated.
