Abstract
An apparatus and method for automatically controlling a drivetrain coupled to at least one drive wheel of a vehicle can include providing a first assembly including a low range drive ratio and a high range drive ratio. An electronic control unit can be configured to receive information from at least one sensor located on the vehicle and to provide an output signal based on the information. An actuator mechanism can be provided and configured to cause the first assembly to operate at a selected one of the low range drive ratio and the high range drive ratio based on instructions from the control unit. Separate algorithms can be provided to determine when to actuate from the high range drive ratio to the low range drive ratio and vice versa.
