摘要： A method for setting a shift point for shifting a transmission for a powered vehicle between a first gear ratio and a second gear ratio. The method includes determining input power data points based on real-time input torque data. The input torque data includes a maximum input torque. The method also includes calculating a gear step value based on the first gear ratio and second gear ratio. The method further includes determining a first power value and computing a second power value based on the gear step value. The first power value and second power value are compared to one another and adjustments are incrementally made in the first power value speed until the difference between first and second power values meets a threshold. The shift point is therefore based on the result of comparing the first power value and the second power value and the corresponding speed associated with the first power value.

摘要： Methods for machine velocity change gear selection and shift execution are disclosed. A current velocity and a maximum velocity change for a work machine from the current velocity may be determined. The maximum velocity change may be based on a maximum amount of energy expended to change the velocity of the work machine without exceeding an operational limit of a work machine component. A selected machine velocity change target gear may be a highest one of the available gears that will not cause a difference between the current velocity and an end of shift velocity of the work machine that is greater than the maximum velocity change so that the maximum amount of energy will not be exceeded. Factors affecting the maximum velocity change may include the grade, the mass of the work machine, and a transmission oil temperature.

摘要： A system and method of controlling the operation of a transmission using fuel consumption data. The system and method includes controlling the operation of a vehicle transmission which is operatively connected to an engine and to a transmission control module having access to a memory. Fuel consumption data for a plurality of engines is converted to engine efficiency loss data representative of the each of the engines' operation. The plurality of patterns, each representative of the operating characteristics of one of plurality of engines, is stored in the memory. Engine operating characteristics are recorded during operation of the vehicle. One of the pluralities of patterns is selected based on the recorded operating characteristics to operate the vehicle in a fuel efficient manner.

摘要： A vehicle includes an engine, dual-clutch transmission (DCT), and controller. The controller executes a method to control a requested change-of-mind shift of the DCT to a second desired gear state. The requested shift is initiated after a prior-requested but not yet fully-executed shift of the DCT to a first desired gear state. The controller detects the requested shift, identifies the second desired gear state, and aborts the prior-requested shift immediately upon identifying the second desired gear state. The controller also shifts the DCT to the second desired gear state using a calibrated shift profile corresponding to the detected shift. The calibrated shift profile describes required oncoming and offgoing clutch torques needed for achieving the second desired gear state. Engine speed control may be used to synchronize engine and input shaft speeds.

摘要： A vehicle includes an engine, a dual-clutch transmission (DCT), and a controller. The controller executes instructions embodying a method to control a requested change-of-mind shift of the DCT to a second desired gear state. The requested change-of-mind shift is initiated after a prior-requested but not yet fully-executed shift of the DCT to a first desired gear state. Execution of the instructions causes the controller to detect the requested change-of-mind shift, identify the second desired gear state, and abort the prior-requested shift to the first desired gear state immediately upon identifying the second desired gear state. The controller also shifts the DCT to the second desired gear state using a calibrated shift profile corresponding to the detected change-of-mind shift. The calibrated shift profile describes required oncoming and offgoing clutch torques needed for achieving the second desired gear state. Engine speed control may be used to synchronize engine and input shaft speeds.

摘要： A system for selecting shift schedules of a transmission of a vehicle includes a controller configured to receive a signal indicative of acceleration of the vehicle prior to a change of a gear of the transmission. The controller is further configured to estimate tractive effort of the vehicle following the change of the gear of the transmission, the tractive effort estimation being based on at least an estimation of a road load on the vehicle. The controller is further configured to select between a first shift schedule and a second shift schedule based on the tractive effort estimation, wherein, if the tractive effort estimation is less than a threshold value, the controller selects the first shift schedule, and if the tractive effort estimation is at least equal to the threshold value, the controller selects the second shift schedule.
