摘要： A control system for a work includes an operating device and a controller. The operating device outputs an operation signal indicative of an operation by an operator. The controller is in communication with the operating device. The controller determines a target profile of a terrain to be worked on. The controller generates a command signal to operate the work implement according to the target profile. The controller receives the operation signal from the operating device. The controller determines an operation of the work implement based on the operation signal. The controller corrects the target profile according to the operation by the operator when the operation of the work implement by the operator is performed.

摘要： A control system for a work vehicle includes a controller. The controller receives actual topography information of a work target. The controller determines a design surface that is positioned below the actual topography. The controller generates a command signal to move the work implement along the design surface. The controller determines if slip of the work vehicle has occurred. The controller raises the design surface when the blade tip of the work implement is positioned below an initial target surface when the slip occurs. The initial target surface is the design surface before the occurrence of the slip.

摘要： A control system for a work vehicle includes a controller. The controller receives actual topography information of a work target. The controller determines a design surface that is positioned below the actual topography. The controller generates a command signal to move a work implement of the work vehicle along the design surface. The controller determines if slip of the work vehicle has occurred. Upon determining that slip has occurred, the controller changes the design surface to a position equal to or higher than a blade tip position of the work implement when the slip occurred.
