ABSTRACT:
A control system/method for an automated transmission system including a splitter-type, semi-blocked mechanical transmission (12) is provided. The control provides a technique for sensing auxiliary section engagement faults or auxiliary section and main section engagement faults and for operation in a fault-tolerant mode upon sensing such faults. In one embodiment, auxiliary section (214) engagement faults are sensed when the main section (212) is confirmed as engaged in an appropriate ratio and the transmission is confirmed as engaged in a ratio (GR.sub.N) other than the target ratio (GR.sub.T). In another embodiment, engagement faults are sensed when one section is confirmed as properly engaged and the transmission does not achieve engagement in a target ratio after a preset period of time.
