Abstract
A system and method for adaptive calibration of a self-propelled work vehicle comprising a chassis and a blade front-mounted thereto for working a ground surface. First sensor signals correspond to a blade slope, and second sensor signals correspond to a chassis slope. During a first operating mode, a blade position is controlled relative to the chassis, based at least on a stored calibration value and a detected difference between the blade slope and a target slope of the ground surface, and a difference is also determined between the chassis slope and the target slope of the ground surface. During a second operating mode, the position of the blade is controlled relative to the chassis until the chassis slope corresponds to the target slope of the ground surface, and the stored calibration value is altered based on adjustments to the blade position during the second operating mode.
