The goal of this project was to evaluate the potential of a controller area network (CAN bus) to be used as the communication network for a distributed control system on an autonomous agricultural vehicle. The prototype system utilized microcontroller-driven nodes to act as control points along a CAN bus. Messages were transferred to the steering, transmission, and hitch control nodes via a task computer. The task computer utilized global positioning system data to generate appropriate control commands. Laboratory and field testing demonstrated that each of the control nodes could function simultaneously over the CAN bus. Results showed that the task computer adequately applied a feedback control model to the system and achieved guidance accuracy levels well within the desired range. Testing also demonstrated the system's ability to complete normal field operations, such as headland turning and implement control. ver the past several years, technology has contin- ued to play an increasing role in agriculture. The industry has recently seen the advent and develop- ment of many types of automated vehicles ranging from planters to sprayers to harvesters. These vehicles have all sustained different levels of automation. Some were capa- ble of fully autonomous field operations, while others were developed for specific control operations such as autosteer- ing (Reid et al., 2000). Commercialization of these technolo- gies has come at a substantial cost to the farmer. Autosteer systems range in cost from $10,000 to $50,000 depending on their accuracy and functionality. The largest component of the system price is the level of global positioning system (GPS) accuracy desired. There has also been a recent increase in the number of electronic components on agricultural equipment. During normal field situations, operators must interact with spray rate controllers, variable rate controllers, and implement system controllers, as well as controls for normal vehicle operation. Attempts have been made to create a standard communication link within all agricultural equipment but have thus far failed within the U.S. The most common
