Patent ID: 8788160

Claim:
A clutch control system for allocating clutch wear during shuttle shifting of a transmission, the transmission being operatively connected to a prime mover to control velocity of a machine, the transmission having a first set of clutches and a second set of clutches, the first set of clutches being operatively connected to an input shaft of the transmission, the second set of clutches including a plurality of directional clutches operatively connected to an output shaft of the transmission, a first clutch of the second set of clutches operating as an engagement clutch, a second clutch of the second set of clutches operating as a first braking clutch, a third clutch of the second set of clutches operating as a second braking clutch, a first of the directional clutches being configured to cause the output shaft to rotate in a first direction, and a second of the directional clutches being configured to cause the output shaft to rotate in a second direction, the second direction being opposite the first direction, comprising: a controller configured to: transmit a first engagement signal to engage the engagement clutch; transmit an isolation signal to disengage a first clutch of the first set of clutches and isolate the prime mover from the directional clutches; transmit a first braking signal to the first braking clutch to apply a first braking force; transmit a second braking signal to the second braking clutch to apply a second braking force, the engagement clutch, the first braking clutch and the second braking clutch cooperating to apply a combined force to slow rotation of the output shaft; transmit a first reduction signal to a first clutch of the second set of clutches to reduce the combined force; transmit a second reduction signal to second clutch of the second set of clutches to reduce the combined force; and transmit a second engagement signal to engage a selected clutch of the first set of clutches upon an occurrence of a designated trigger event.
