摘要： A sensor-equipped wheel support bearing assembly is provided which performs high-accuracy load estimation without providing with another sensor, even in a state where a ground contact load on a wheel supported by the bearing is very low as compared to other wheels. The assembly includes: a plurality of sensor units (20) detecting a load on a wheel support bearing segment (100); sensor signal calculator (31) processing sensor signals (S) from the units; and load calculation processor (32) calculating a load on a road surface contact point on a wheel, based on the processed information. The processor (32) determines whether a target wheel is in a predetermined low load state, based on information of a detected load on a wheel other than the target wheel; and switches a load calculation scheme in accordance with a result of the determination to calculate a load on the wheel.

摘要： A method for estimating the magnitude of a tire force acting on a rolling tire is disclosed, wherein: using at least seven sensors mounted on a tire sidewall portion, surface strain is simultaneously measured at seven measuring positions; with respect to a combination of the seven measuring positions, a coefficient matrix representing correlation with seven force components is defined, and a equation including the coefficient matrix is defined; using the data on the surface strain measured with the sensors, the equation is computed to find at least one of the seven force components, e.g. air pressure. The estimated air pressure is compared with a reference pressure, to determine whether the tire pressure is dropped or not. Further, a secondary sensor is mounted in a peculiar region where the surface strain is substantially not affected by the vertical load.

摘要： This invention is intended to enable performing a vehicle straight-line performance adjustment operation surely in a short time without the need of operator's skill. An actually moving state of a vehicle completed with an alignment adjustment is reproduced after the vehicle is mounted on rollers of a bench tester, and the side force of each of wheels at this time is measured, it is determined whether or not the measured side force is within a preset reference range, it is determined whether or not the side force of the wheel, which has been determined to be out of the reference range, is within the reference range when a toe angle of the wheel is corrected within a preset toe angle correction allowable range, the toe angle is corrected within the correction allowable range when it is determined that the side force falls within the reference range, and the side force is corrected to fall within the reference range, the side force of the each wheel after the toe angle is corrected is obtained, a drift amount of the vehicle is calculated from the obtained side force of the each wheel, and it is determined whether or not the vehicle has a good straight-line performance based on the calculated drift amount.

摘要： The invention makes it possible to measure a lateral displacement amount of a vehicle accurately in a short time on a bench testing machine without damaging a vehicle body and tires.Respective rollers 1F, 1R on which respective wheels WF, WR of the vehicle A are placed respectively are made movable in a lateral direction. In a state in which the respective wheels WF, WR are rotating at a predetermined speed, lateral forces (cornering forces) acting on the respective rollers 1F, 1R are detected by respective detectors 3. Then, a yaw angle speed when the vehicle A is brought into a state of steady circular turning is calculated based on the lateral forces acting on the respective rollers 1F, 1R and the lateral displacement amount is calculated from the yaw angle speed.
