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.

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.
摘要翻译：本发明旨在使得能够在短时间内确实地执行车辆直线性能调整操作，而不需要操作者的技能。在将车辆安装在台架试验机的滚子上之后，重新进行具有对准调整的车辆的实际移动状态，并且测量此时的每个车轮的侧向力，确定测量的侧向力在预设的参考范围内，当在预设的脚趾中校正车轮的脚趾角度时，确定已经被确定为在参考范围之外的车轮的侧向力是否在参考范围内角度校正允许范围时，当确定侧力落在参考范围内，并且侧力被校正为落在参考范围内时，在修正允许范围内修正趾角，每个车轮的侧向力在获得脚趾角度，根据所获得的每个车轮的侧力来计算车辆的漂移量，并且确定车辆是否具有良好的直线基于计算漂移量的线性能。
