20100121543 | Method for controlling gear ratio changes in an automatic transmission - A method of controlling an automatic transmission of a machine includes a step of identifying an upcoming gear ratio change from a current gear ratio to a proposed gear ratio. An estimated power output value, based on the proposed gear ratio and a current engine speed, is determined. The estimated power output value is adjusted based on a derated operating condition. If the estimated power output value is greater than or equal to a current power output value, a gear evaluation identifier is set to a first value. If the estimated power output value is less than the current power output value, the gear evaluation identifier is set to a second value. | 05-13-2010 |

20150198239 | CONTROL SYSTEM FOR HYBRID POWERTRAIN - A control system for a hybrid powertrain including a transmission and a hybrid system is provided. The control system includes a memory unit, and a controller. The memory unit is configured to store at least one shift map therein. The controller is coupled to the memory unit, the transmission, and the hybrid system. The controller is configured to receive an operating state of the transmission and the hybrid system. The controller is further configured to determine if the received operating state meets a gearshift criteria with the at least one shift map, and trigger one or more gearshifts in the transmission based on the determination. | 07-16-2015 |
