Research on Cruise Control of Hydrostatic Tractor Based on CAN Bus

Hydrostatic tractor is an agent tool of artificial intelligence mechanical transmission system. In order to improve the automatic control level of driving path in constant speed cruise of hydrostatic tractor, a constant speed cruise control method of hydrostatic tractor based on CAN bus control and kinematic parameter fusion analysis is proposed. The kinematic planning model of hydrostatic tractor moving in constant-speed cruise is constructed, the visual characteristic parameters of hydrostatic tractor moving in constant-speed cruise are extracted by the method of visual perception of unknown environment of hydrostatic tractor, and the path space parameters capture and obstacle avoidance parameters fitting of hydrostatic tractor moving in constant-speed cruise are realized by CAN bus learning and man-machine interface parameter fitting method. Using the method of fitting and tracking discrete points of driving trajectory, combined with path planning and visual parameter tracking and identification methods, the adaptive control and spatial movement planning design of driving path of hydrostatic transmission tractor in constant speed cruise are realized. The test results show that this method has strong environmental adaptability and high control robustness, and improves the accuracy of constant-speed cruise control of hydrostatic tractor.
