Abstract
An apparatus and method are provided for assisting an operator of a motor grader to steer the motor grader in a crab steer mode. The method includes receiving an operator selection of an automatic crab steer mode, determining that a condition of the motor grader is such as to permit automatic crab steer, and receiving an operator steering command. The received operator steering command is converted to an articulation command to place the machine into a crab steer mode. The articulation command is executed and is also converted into a final steering command consistent with the articulation command, and the final steering command is then executed.
