Abstract Aiming at the problem of motion instability caused by the climbing of intelligent vehicles in the process of warehouse transportation, a design of intelligent variable speed warehouse transport vehicle system was proposed. STM32F103C8T6 single-chip microcomputer is used as the core controller of the intelligent variable speed car. The hardware circuit of the system is composed of power module, servo motor module, ultrasonic sensor module, infrared sensor module, MPU6050 gyroscope, motor drive and other modules. At the same time, the software test of vehicle downhill intelligent transportation, tracking detection speed and differential steering conditions is completed. Finally, the performance of the car is verified, and the results show that the smart car has achieved high stability of avoidance tracking, speed and other key functions. It is a downhill process, which has a lot of practical value.
