Four-hub motor driven unmanned electric tractor control system

Abstract

The invention discloses a four-hub motor driven unmanned electric tractor control system, which comprises a whole vehicle control system, an unmanned driving system, a power battery system, a hub motor driving system, a braking system, a steering system, a PTO power output system, a suspension lifting system, an obstacle avoidance system, a heat dissipation system, a hydraulic system and a fault monitoring and protecting system. The whole vehicle control system is a whole vehicle main control unit. The unmanned driving system is used for autonomously carrying out path planning and vehicle attitude correction; the power battery system is used as a power source of the whole vehicle; the hub motor driving system is used for controlling a hub motor to achieve four-wheel independent driving; and the braking system achieves four-wheel independent driving braking and parking braking. The four-hub motor driven unmanned electric tractor control system can intelligently control a four-wheel unmanned electric tractor and meet the operation requirements of multiple modes and multiple terrains.

Description

technical field [0001] The invention relates to the technical field of control systems, in particular to a control system and method for an unmanned electric tractor driven by four-wheel hub motors. Background technique [0002] With the accelerated development of my country's agricultural modernization, the task of upgrading the agricultural machinery product technology innovation industry and transforming the agricultural development mode is more urgent. Accelerating the development of intelligent agricultural machinery equipment technology and the transformation of agricultural machinery equipment from mechanization to intelligence and informationization are of great significance to supporting the development of modern agriculture. major. Tractors are the most common in agricultural applications. The four-wheel drive unmanned pure electric tractor integrating new energy technology, hub motor drive technology and driverless technology will open a new development field for t...

Problems solved by technology

[0003] At present, domestic unmanned tractors are mostly electrified on the basis of traditional fuel tractors, and still adopt the control mode of front wheel steering and rear wheel drive. The degree of integration and intelligence is not high, and there is a cooperative control of various components. Disadvantages of complexity, single turning mode, large turning radius, and inability to adapt to the needs of various terrain operations
