Abstract

The invention provides an automatic driving system of a tractor, a control method and a crawler-type tractor. The automatic driving system comprises a GNSS navigation positioning system, a visual navigation system, a controller and an actuator; wherein the GNSS navigation positioning system and the visual navigation system are respectively connected with the controller; the actuator is connected with the controller; the controller controls the operation of the tractor through the actuator; the GNSS navigation positioning system is used for acquiring the longitude and latitude geographic position, the satellite differential information and the operation boundary information of the tractor; and the visual navigation system is used for acquiring the running path, the obstacle and the crop information of the tractor and judging the running path of the tractor. When the scheme is adopted, the operation accuracy of the crawler-type tractor can be improved, the operation error is reduced, thestandardization degree of agricultural production can be improved, and the land utilization rate and the agricultural production efficiency can be improved. The production cost is reduced, the fatigue degree of a driver is reduced, and the labor force is saved.

Description

technical field [0001] The invention belongs to the technical field of tractors, and in particular relates to a tractor automatic driving system, a control method and a crawler tractor. Background technique [0002] As the main labor force in agricultural mechanized production, crawler tractors can complete most of the work in the field by hanging or pulling different agricultural implements; however, due to the relatively harsh working environment of crawler tractors, problems such as driving deviations that are inevitable in manual driving , leading to low overall operation accuracy of crawler tractors and low land utilization rate; traditional crawler tractor driving work is completely dependent on the driver's driving conditions, and it is difficult to achieve high-precision operation requirements during long-term straight-line operations , which directly results in an increase in production costs and labor costs, and greatly reduces the efficiency of land use; therefore...
