AUTOMATIC GUIDANCE SYSTEM OF AGRICULTURAL VEHICLES BASED ON CAN BUS

摘要：

A navigation control system for agricultural machinery was developed which based on CAN bus. ISO 11783 was the standardization for the exchange of information between different devices in the system. The system includes the control termination, GPS signal acquisition unit, digital compass signal acquisition unit, angle sensor signal acquisition unit and steering control unit. A self-adaptive PID algorithm was adopted to achieve steering control. The communication experience proved the effectiveness of the system in collecting data and transmitting instruction. Experimental results showed that the algorithm could quickly track target value, and made the system have better dynamic response characteristics.
