Abstract
A work vehicle may include a chassis, a ground-engaging blade, a sensor, and a controller. The ground-engaging blade may be movably connected to the chassis via a linkage configured to allow the blade to be raised or lowered relative to the chassis. The sensor may be connected to the chassis at a fixed relative position to the chassis and configured to provide a pitch signal indicative of a rotational velocity in a pitch direction. The controller may be configured to receive the pitch signal and send a command to raise or lower the blade, the command based on a first gain and the pitch signal when the pitch signal indicates a rotational velocity in a first direction and based on a second gain and the pitch signal when the pitch signal indicates a rotational velocity in a second direction.
