Adjustable self-adaptive load reversing control device and control method for tractor

Abstract

The invention relates to an adjustable self-adaptive load reversing control device and method for a tractor. The adjustable self-adaptive load reversing control device comprises a load reversing control device and a control module of the load reversing control device. The operation intention of a driver is judged according to information collected by the signal collecting module, operation of the driver is divided into a starting mode and a reversing mode, the optimal clutch combination requirement torque curve under the current load and the current vehicle speed is automatically calculated, the problem that starting and reversing impact of a tractor under different loads and different working conditions is large is effectively solved, and the reliability of the tractor is improved. Tractor starting and reversing speeds suitable for the tractor are adjusted through the reversing sensitivity adjusting knob, so that starting and reversing control of the tractor is more adaptive, and mechanical impact on the tractor in the starting and reversing processes of the tractor is effectively reduced. The driving comfort of the tractor is improved, and meanwhile a platform is provided for further intelligent development of the tractor.

Description

technical field [0001] The invention belongs to the field of tractor control, in particular to a tractor adjustable self-adaptive load reversing control device and a control method. Background technique [0002] The traditional mechanical reversing tractor, no matter starting or reversing, needs to step on the clutch pedal, then engage the forward or reverse gear, and release the clutch pedal at a suitable speed to complete the starting or reversing. The speed of the clutch release is directly A series of problems will affect whether the tractor can start normally, whether the engine will stall due to excessive load, and whether the starting shock is large. Therefore, driving a traditional mechanically reversing tractor requires the driver to have rich driving experience and operating skills. In addition, the operation of the traditional mechanical reversing tractor in the starting and reversing process is relatively complicated, and the operation efficiency will also be red...
