Abstract: Intelligent harvester unmanned driving system mainly includes the development of CAN network architecture and control strategy software development.The control strategy software includes the management of the operation mode and switching of the whole machine, the automatic control of the key operation parts, the development of the safety control function, the development of the remote control system, and the matching development of the automatic navigation system.Multiple control parts are organically combined with intelligent switching to ensure the reliability, operation accuracy and safety of the working parts under unmanned driving conditions.The application of intelligent harvester unmanned control system greatly reduces labor, workload and solves the problem of unavailability during busy farming time.
