Driver assistant system for crawler tractor

Abstract

The invention relates to a driver assistant system for a crawler tractor. The driver assistant system for the crawler tractor comprises a display with a built-in inertial navigation unit, a differential positioning device, a rotation speed sensor and a controller, wherein the display, the differential positioning device and the rotation speed sensor are connected with the controller; the display is used for acquiring the attitude information and running path information of the crawler tractor through the inertial navigation unit; the differential positioning device is used for acquiring a satellite differential signal according to the positioning information from a GNSS and the positioning information from a base station; the rotation speed sensor is used for acquiring the rotation speed information of crawlers at two sides of the crawler tractor; and the controller is used for controlling a crawler driving device to adjust the rotation speed of the crawlers according to the attitude information and running path information of the crawler tractor, the satellite differential signal and the rotation speed information from the inertial navigation unit and the GNSS, so as to correct the deviation of the crawler tractor. The driver assistant system for the crawler tractor can improve the accuracy of agricultural machinery operation, reduce operation errors, improve the agriculturalproduction efficiency, reduce the production cost, reduce the fatigue degree of a driver and save the labor force.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to an auxiliary driving system for 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 and the inevitable driving deviation in manual driving, the overall operating accuracy of crawler tractors is not high, and the land utilization rate is low. [0003] The driving work of crawler tractors in the prior art is completely dependent on the driving conditions of the driver. During long-term straight-line operations, it is difficult to meet the high-precision operation requirements, which directly causes an increase in production costs and labor costs, and greatly reduces land use efficiency. Therefore, the realization o...
