Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] Such as figure 1 As shown, a tractor intelligent control method, the steps are as follows:

[0027] a) Monitor the road conditions and set the limit slip rate corresponding to the current road conditions;

[0028] b) judging whether the real-time slip rate is less than the limit slip rate corresponding to the current road condition;

[0029] c) If the real-time slip rate is greater than or equal to the limit slip rate corresponding to the current road conditions, further judge whether the tractor is overloaded, if not, reduce the throttle opening and brake; if overloaded, reduce the throttle Open, brake and cut off the power output of the engine to the power system, and lift the agricultural implements.

[0030] When the tractor is in an excessive slipping or overloading state, the above method can relieve the excessive slipping or overloading state...

Abstract

The invention relates to a tractor intelligent control method and an intelligent control system. A corresponding signal is collected by a sensor to obtain an existing operating state of a tractor, all parameters are calculated, analyzed and judged by a controller on the basis, and after information is processed, control signals are transmitted to a stepping motor and a high-speed electromagnetic valve so as to enable a main clutch, a PTO clutch, and a brake pedal executing mechanism, an engine throttle draw bar executing mechanism, a hydraulic hanging mechanism and the like to conduct motion to prevent a driving wheel of the tractor from excessive trackslip and overload of a transmission system, ensure good comfort, fuel economy and traction, and prolong service life of the transmission system and tires of the tractor.

Description

technical field [0001] The invention relates to an intelligent control method and an intelligent control system for a tractor. Background technique [0002] Tractors are the main driving force for farmland operations in our country. However, due to the limitation of adhesion during plowing operations, tractor driving wheels slip seriously, especially on uncultivated land. When a wheeled tractor is running at a high slip rate, the drive train will be unstable, resulting in strong self-excited vibration, which not only affects the comfort of the tractor, but also significantly reduces its traction performance, increases fuel consumption, and causes rapid tire wear. When the tractor is working with agricultural machinery in the farmland, the working resistance will change due to the change of the soil condition, especially when the agricultural machinery touches debris such as stones and wooden piles in the soil, the working resistance will suddenly increase. A sudden increase...
