Description
Technical Field
The application relates to the technical field of vehicles, in particular to a real-time measuring device for actual rotation angle of a wheel.
Background
The existing steering-by-wire system of the automatic driving vehicle needs to detect the rotation angle and the angular speed of the front wheels so as to realize the closed-loop control of the steering process of the vehicle. The wheel actually rotates around the kingpin, but the rotation track of the wheel is an arc line in space due to the existence of the kingpin caster angle and the inward inclination angle, so that the accurate measurement difficulty of the wheel rotation angle is high, and the problems of expensive measuring device, inaccurate measuring data and the like exist in most of the prior art.
According to the definition of the wheel rotation angle by SAE Vehicle Dynamics Terminology in the United states, the rotation angle which actually affects the running of the automobile is the rotation angle of the wheel around a Z axis perpendicular to the ground.
At present, two methods for measuring the wheel rotation angle mainly exist, the first method is obtained by calculating the transmission ratio of a steering system, the method obtains the rotation angle of a steering wheel from a sensor arranged in a steering power-assisted motor, and then the wheel rotation angle is calculated by the steering transmission ratio and the steering wheel rotation angle, and the calculation of the method is complex and the error caused by uncertainty factors on the measured value of the wheel rotation angle is difficult to eliminate because the steering transmission ratio is often nonlinear.
Another method is to directly measure the rotation angle of the damper, approximate the rotation angle of the damper to the rotation angle of the wheel, and the method is applicable to vehicles in which the kingpin coincides with the damper axis, and for vehicles in which the wheel rotates around the virtual kingpin, the first method is generally adopted. The method is to connect the angle sensor with the vibration absorber, and output the rotation angle of the vibration absorber through the sensor, but the error exists between the measured rotation angle and the actual rotation angle of the wheel due to the existence of the caster angle and the internal inclination angle of the kingpin, and the error also increases along with the increase of the rotation angle of the wheel.
Both of the above-mentioned conventional methods do not consider the load of the vehicle and the change of road surface conditions, resulting in errors in measured data caused by stress deformation of the suspension and the wheels, so that both methods can only obtain rough values of wheel rotation angles, but still need to be improved in terms of accuracy.
Therefore, how to accurately measure the wheel rotation angle during the running of the vehicle and ensure the measurement accuracy is a technical problem to be solved by the person skilled in the art.

the measuring mechanism 200 comprises a rotary encoder 210, an encoder bracket 220 and a rotary rod 230; as shown in fig. 6, the rotary encoder 210 is mounted on the slider frame 120 through an encoder bracket 220;

The rotating lever 230 in the measuring mechanism 200 is horizontally installed. Since the fork arm 310 rotates along with the rotation of the wheel 7, the rotation angle of the fork arm 310 in the direction perpendicular to the ground is the wheel rotation angle, and since the top end of the fork arm 310 is in limited installation with the rotating rod 230, the rotating rod 230 is driven to rotate while the fork arm 310 rotates, and meanwhile, since the rotating rod 230 always keeps horizontal in the moving process, the rotation angle of the rotating rod 230 is the rotation angle of the fork arm 310 around the direction perpendicular to the Z axis of the ground, the action of the rotating rod 230 can be equivalently understood as simulating the wheel axis a or b in fig. 1, and the rotation angle of the rotating rod 230 is the wheel axis change angle of the wheel 7, namely the wheel rotation angle, so that the wheel rotation angle can be obtained only by measuring the rotation angle of the rotating rod 230.
The actual movement track of the wheel 7 during actual rotation is approximately regarded as an arc, so that the movement track of the rotating rod 230 in space is also approximately regarded as an arc, which moves in the lateral direction while rotating around the autogenous axis, so that the rotation angle is measured after the degree of freedom of the movement of the rotating rod 230 in the lateral direction is offset by adding the sliding mechanism 100 when measuring the rotation angle of the rotating rod 230.
