Abstract

The invention provides a road roller and a motion control device and method thereof. The motion control device comprises a position sensing device for sensing position information of an operation lever, and a controller connected with the position sensing device, wherein the controller is used for automatically adjusting driving current output to a travel pump according to the preset current-time relation curve which is in one-to-one correspondence with each motion indication range when the position sensor senses that the operation lever is positioned in each motion indication range; and each motion indication range comprises at least one of a forward indication position range, a backward indication position range or a stopping indication position range. According to the invention, the driving current output to the travel pump can be automatically adjusted, thereby the automatic adjustment on the operation speed of the road roller can be realized.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a road roller and a motion control device and method thereof. Background technique [0002] When the road roller compacts the asphalt for road construction, it usually compacts back and forth on the road surface of 10 to 100 meters within a certain temperature range. Cyclic operation and parking operation of high-speed driving and other processes. Good starting / accelerating, stopping / decelerating effects and maintaining a steady speed for compaction are critical to construction quality. These processes require the roller operator to constantly change direction, accelerate, decelerate and control the steady speed. [0003] At present, the widely used method is: the operator of the road roller manipulates the joystick or handle to drive the driving hydraulic pump or output an electronic signal proportional to the movement angle of the joystick to control the driving hydraulic...
