Aiming at the problems of difficult operation of sugarcane transporter in the hilly area and easy rollover accidents during the transfer process, a leveling control system for the scissor sugarcane transporter was designed. By building a sugarcane transporter test platform, the automatic leveling function of the body attitude was realized before sugarcane transfer based on the state measurement unit, single-chip embedded system, and hydraulic system. The function kept the body state within a safe range, and controlled the lifting and turning of the carriage to complete the actions required for the sugarcane transfer process. In order to study the factors affecting the stability of the car body, a critical operation test was carried out on the test platform with load of 120kg. The state parameters were selected as the lateral angle of the vehicle body as 0°, 2°, 4°, 6° and 8°, and the lateral span of the supporting structure as 490mm, 650mm, and 730mm, respectively. And the automatic leveling test was carried to verify the reliability of the stable control of the system using the “chasing” leveling strategy. The results showed that the lateral angle of the vehicle body and the span of the chassis support structure had a significant impact on its stability, and 730mm was the best lateral span of the support structure;when the lateral span of the supporting structure was 490mm and the initial lateral angle of the body was 6°, it was a critical state, and the sugarcane transportation process had safety risks. The designed system can level the transporter within 20s, and the accuracy can reach 0.3°;when the car body passed the leveling safety test, the vehicle can complete unloading operations such as car lift and transfer within 35s, satisfying the safety transfer and unloading within 60s. The control system improved the safety and work efficiency of sugarcane transporter in hilly areas.
