Research on the structural design of assisted driving robots

With the development of the automobile industry, people have put forward higher requirements for the safety, reliability, durability and other performance of automotive products. In order to accurately detect the operation of the car under the actual road conditions, it is usually necessary to carry out a car test drive experiment, and the experimental results can detect the damage and deformation of the mechanical structure of the car under high-speed movement, and the fatigue damage of the mechanism or parts under the condition of the car under long-term driving. But this dangerous and extreme work cannot be driven by humans. Therefore, the car driving robot was born, which has higher precision, greater safety, lower test drive cost than human driving, and the fatigue driving limit is much higher than that of human drivers. However, there are many disadvantages to the driving robot that has been used in production. For example, the steering wheel angle accuracy ≥ 1 ° / S, the control accuracy of the mechanical leg movement position of the control throttle clutch is above 3mm [1], and the positioning accuracy of the equipped in the inner chamber of the car is difficult to guarantee. Therefore, this study focuses on the optimization of the structure according to the corresponding control accuracy requirements, and tries to design a positioning scheme with a smaller positioning error, a control scheme with lower cost control costs, and a stress analysis of some mechanical parts.
