Embodiment Construction
[0014] The present invention will be further described below according to the embodiments provided by the accompanying drawings.
[0015] The first part, detection principle.
[0016] Pre-test preparation stage: when the car is turning, the axes of all the wheels intersect at one point, and all the wheels move around a common center of circle, which is called the steering center O point 16 of the car. This steering center O point 16 is the intersection of the radial straight line passing through the center of the front outer wheel and the front inner wheel of the vehicle and perpendicular to the plane of the front wheel and the extension line passing through the axis of the rear axle of the vehicle. When the vehicle is turning around the turning center O point 16, all points on the vehicle perform circular motion around the turning center O point 16, because the turning center O point 16 is on the extension line of the rear axle axis of the vehicle, and the rear axle axis is p...
