Abstract:
A work vehicle includes a boom, an arm, a bucket, an arm control member, a speed limit determination portion, and a target speed determination portion. The speed limit determination portion determines a speed limit for limiting a speed of a cutting edge of the bucket in accordance with a distance between a cutting edge and a design surface. The target speed determination portion determines a target speed of the boom based on the speed limit. The speed limit determination portion decides on a speed limit calculated based on correlation between the speed limit and the distance between the design surface and the cutting edge when an amount of operation of the arm control member is equal to or greater than a prescribed amount and decides on a speed limit lower than the speed limit calculated based on the correlation when the amount of operation is smaller than the prescribed amount.
