Abstract
A work vehicle may include a chassis, a ground-engaging blade, a sensor assembly, and a controller. The blade may be movably connected to the chassis via a linkage assembly configured to allow the blade to be raised and lowered relative to the chassis. The sensor assembly may be configured to provide a chassis inclination signal indicative of an angle of the chassis relative to the direction of gravity and a blade inclination signal indicative of an angle of the blade relative to one of the chassis and the direction of gravity. The controller may be configured to receive the chassis and blade inclination signals, determine a target grade, determine a distance error based on the signals indicative of a distance between the blade and the target grade, and send a command to move the blade toward the target grade based on the distance error.
