CONTROL SYSTEM FOR WORK VEHICLE, CONTROL METHOD, AND WORK VEHICLE
First Claim
1. A control system for a work vehicle, the system comprising:
- a current terrain acquisition device that acquires current terrain information indicating a current terrain to be worked; and
a controller configured todecide a virtual design surface located below the current terrain, the virtual design surface having an inclination angle,generate a command signal to a work implement of the work vehicle to move the work implement along the virtual design surface,update the current terrain information with the current terrain acquisition device as movement proceeds, andmodify the inclination angle according to the updated current terrain information.

Abstract
A current terrain acquisition device acquires current terrain information indicating the current terrain to be worked. A controller is configured to decide a virtual design surface that is located below the current terrain and has an inclination angle. The controller is configured to generate a command signal to the work implement of the work vehicle to move the work implement along the virtual design surface. The controller is configured to update the current terrain information with the current terrain acquisition device as the movement proceeds, and change the inclination angle with the updated current terrain information.

8. A method for controlling a work vehicle, the method comprising:
-
acquiring current terrain information indicating a current terrain to be worked; deciding an inclined virtual design surface located below the current terrain; and generating a command signal to a work implement of the work vehicle to move the work implement along the virtual design surface, the virtual design surface being decided so that an inclination angle of the virtual design surface gradually decreases, by repeatedly updating the current terrain and deciding the virtual design surface.
