At present, the rotation of a steering wheel of a motor vehicle is detected by installing a photoelectric encoder on a transmission shaft of the steering wheel, rotating a movable shaft of the photoelectric encoder and the steering wheel together, and outputting counting pulses through the photoelectric encoder to realize the detection of the rotation angle and the rotation angular speed of the steering wheel. The method needs to greatly reform the motor vehicle, and has long installation period and much expenditure and use; in addition, in the later equipment maintenance, the vehicle needs to be disassembled again, which wastes time and labor; in the long-time use process, due to error accumulation, the precision of detection of the rotation angle and the rotation angular speed of the steering wheel is reduced, and the control effect of the steering wheel is influenced.
Because the traditional detection device for the rotation angle and the rotation angular speed of the steering wheel has high use cost and difficult maintenance, the control state of the steering wheel is detected in an indirect mode, namely, a machine vision technology is adopted to judge whether the detected motor vehicle keeps a proper safe distance with other peripheral targets. The method belongs to post qualitative detection, and the driving direction of the motor vehicle cannot be pre-judged through the detection of a steering wheel, so that possible potential safety hazards are actively avoided. In addition, the method has large detection error, and cannot accurately describe the operation state of the steering wheel, so that the driver cannot automatically judge whether the steering wheel is operated correctly.

The function of the steering wheel is to convert the force applied by the driver to the rim of the steering wheel into torque and transmit the torque to the steering shaft and the steering wheel, and the gear system introduced between the driver and the wheels is flexible in operation, thereby well isolating the violent vibration from the road.
