Abstract: A work vehicle includes a work implement. A control system for the work vehicle includes a controller. The controller acquires work range data indicative of a work range. The controller determines a division distance by dividing an entire length of the work range by a predetermined number of divisions. The controller determines a plurality of starting positions so that the distance between each starting position matches the division distance in the work range. The controller generates an instruction signal to actuate the work implement from the plurality of starting positions.

Abstract: A controller controls the steering device so as to cause a vehicle body to turn toward the left when a left steering lever is operated without a right steering lever being operated. The controller controls the steering device so as to cause the vehicle body to turn toward the right when the right steering lever is operated without the left steering lever being operated. The controller reduces the rotation speed of the engine when both the left steering lever and the right steering lever are operated and both the operation amount of the left steering lever and the operation amount of the right steering lever are equal to or greater than a first threshold.

Abstract: A work vehicle includes a work implement. A control system for the work vehicle includes a controller. The controller determines a target design terrain indicating a target trajectory of the work implement, and operates the work implement to dump materials on a current terrain sequentially from a nearer side to a farther side of the work vehicle in accordance with the target design terrain. At least a part of the target design terrain is located above the current terrain.

Abstract: The camera captures an image of a surrounding environment of a work vehicle and outputs image data indicative of the image. The shape sensor measures a three-dimensional shape of the surrounding environment and outputs 3D shape data indicative of the three-dimensional shape. A controller acquires the image data and the 3D shape data. The controller generates a three-dimensional projection model based on the 3D shape data. The three-dimensional projection model portrays the three-dimensional shape of the surrounding environment. The image is projected onto the three-dimensional projection model based on the image data, thereby generating display image data that represents a display image of the surrounding environment of the work vehicle.
