Problems solved by technology

[0004]The existing technical solutions usually need to be equipped with two force sensors, which increases the product cost and also increases the failure points. In addition, the tension sensor solution is less applicable to plowing operations. Good, poor adaptability to working conditions that use power output such as rotary tillage

Abstract

The invention relates to the technical field of electric control, and discloses a tractor lifter control method and device, a storage medium and a tractor. The method comprises the steps that operation parameters of the electronic control engine are obtained; determining a load sudden change coefficient, a soil hardness change coefficient and an actual engine-torque percentage according to the operation parameters of the electronic control engine; determining a force control parameter of the lifter according to the load mutation coefficient, the soil hardness change coefficient and the actual engine-torque percentage; and adjusting the rotating speed of the electric control engine or the height of the lifter according to the force control parameters to enable the force control parameters to be within a preset range. A force sensor does not need to be configured, the product cost is reduced, and meanwhile fault points are reduced; the system composition is simplified, and the cost is reduced; the device is suitable for plowing operation, and the adaptability of power output operation working conditions such as rotary tillage is improved.

Description

technical field [0001] The invention relates to the technical field of electronic control, in particular to a control method for a tractor lifter, a device storage medium and a tractor. Background technique [0002] In tractor farmland operations, the lifter controls the depth of entry into the soil of the supporting equipment, which has a great impact on the quality of the operation. At present, the electronically controlled hoist usually has three modes: position control, force control and force-position comprehensive control. The center control is to keep the position of the lifter relative to the vehicle unchanged during the operation, the force control is to keep the traction force constant during the operation, and the force-position comprehensive control combines force control and position control. Proportional adjustment of lifter traction and position. [0003] At present, in order to realize force control and position control, the electric control lifter is usual...
