Method and apparatus for controlling a mobile machine during start-up

A computer-based method for controlling a mobile machine during start-up, the mobile machine having an engine, a drive train, and at least one auxiliary system;

• the drive train and the at least one auxiliary system being controllably driven by the engine, including the steps of:
• determining an actual angle of steering of the mobile machine;
• comparing the actual angle of steering with a desired angle of steering;
• starting the engine;
• enabling engagement of the at least one auxiliary system;
• and
• disabling engagement of the drive train in response to the difference between the actual angle of steering and the desired angle of steering being greater than a predetermined threshold value.
