Abstract
An industrial machine and methods for providing automatic tilt control for the same. One method includes determining a current tooth vector of a tooth included on a bucket of the industrial machine and a current path vector of the tooth and determining a current digging angle between the current tooth vector and the current path vector. The method also includes determining a delta angle based on the current digging angle and a target angle and automatically adjusting a tilt of the bucket based on the delta angle.
