Claim 16:
17. A leveling control device, comprising:
an acquiring module configured to respectively acquire an elevation of a current position of a blade of a motor grader, an elevation of a target position, and a movement speed of the motor grader, wherein the target position is on the ground with a certain horizontal distance from the current position along a movement direction of the motor grader;
a first determining module configured to determine a movement time of the blade from the current position to the target position according to the horizontal distance and the movement speed;
a second determining module configured to determine a lifting speed of a lifting cylinder according to an elevation difference between the elevation of the target position and the elevation of the current position and the movement time; and
a controlling module configured to control the lifting cylinder to adjust the blade to reach the target position from the current position according to the lifting speed,
wherein the acquiring an elevation of a target position comprises: respectively acquiring an elevation of a Global Positioning System (GPS) and a vertical distance between the GPS and the target position, wherein the GPS is fixedly arranged relative to a frame of the motor grader, and acquiring the elevation of the target position according to the elevation of the GPS and the vertical distance between the GPS and the target position.
