DESIGN OF SMALL UNMANNED VEHICLE INTELLIGENT TRANSMISSION SYSTEM BASED ON PID CONTROL ALGORITHM MECHANICAL STRENGTH OF STRIPPED OPTICAL FIBER

As the future development direction of automobiles, unmanned driving has received wide attention from all walks of life. Unmanned shifting technology plays an important role in the overall performance of driverless driving.The small unmanned vehicle intelligent shifting system based on PID control algorithm is designed in this paper. After the environmental information around the vehicle is collected by the laser radar high-speed data acquisition module, it is transmitted to the decision-making planning module.According to the detailed information, the corresponding operation instructions are given to the driverless smart car. Operational commands are transmitted to the motor drive module to control intelligent shifting. Therefore, the vehicle dynamics model is constructed, and the speed control strategy based on the improved PID control algorithm is used to complete the intelligent shift control of the unmanned vehicle. The experimental results show that the system can effectively control the intelligent shifting of the unmanned vehicle under different scene settings, and the control effect is ideal, as well as it has good control efficiency and can meet the requirements of the variable speed control of the unmanned vehicle.
