Abstract
A default mode control system for controlling a split torque transmission is disclosed. The default mode control system monitors various inputs to the control to detect an on board electrical, electronic fault or mechanical, hydraulic fault. When a fault is detected, the default mode control will recover from the default and then will limit operation of the split torque transmission based on the fault input.
Claims6
A method for controlling a split torque transmission during a default mode, the split torque transmission having a hydrostatic transmission, a mechanical transmission, and a transmission control, comprising the steps of:
- sensing the hydrostatic transmission, the mechanical transmission and a plurality of electrical components in the transmission control;
- detecting a fault within the sensed transmission control;
- detecting an event within the mechanical transmission and the hydrostatic transmission;
- and
- controlling the split torque transmission relative to the detected fault in the transmission control or the detected event in the split torque transmission.
