Abstract
A work vehicle may comprise a chassis, a ground-engaging blade, a sensor assembly, and a controller. The ground-engaging blade may be movably connected to the chassis via a linkage configured to allow the blade to be tilted relative to the chassis. The sensor assembly may be connected to the work vehicle and configured to provide a tilt signal indicative of an angle of the blade in a roll direction and a roll signal indicative of a rotational velocity of the blade in the roll direction. The controller may be configured to determine a target tilt angle, receive the tilt signal, receive the roll signal, and send a command to tilt the blade toward the target tilt angle, the command based on the tilt signal, the roll signal, and the target tilt angle.
