Abstract
A method of operating a machine having a lockable differential includes monitoring a first operating parameter indicative of wheel slip, and monitoring a second operating parameter different from the first parameter, the method further including controlling locking and unlocking of the differential responsive to the second operating parameter. A machine is provided having an electronic controller including software control logic for controlling locking and unlocking of a differential, the electronic controller being configured to lock the differential where the machine is in an operating mode where wheel slip is likely, such as a digging/dozing mode. Satisfaction of criteria for locking may be recognition by the controller of a predetermined pattern of sensor inputs corresponding with a likely wheel slip condition, or actual slip detection.
