    摘要: Engine monitor/control microprocessor primarily effective to automatically adjust the engine power setting in a transmission power train in which the transmission drive reduction is variable in ratio, by step change or continuously so, such as for use in farm tractors. The microprocessor adjusts the position of the setting so that engine power set at all levels is produced at the right brake specific fuel consumption for substantially minimum pounds of fuel per horsepower hour, or within a band width thereof if not all that sensitive. Preferably, the microprocessor has a higher priority primary function of also automatically adjusting the transmission drive reduction ratio, for the same purpose but with high sensitivity.

    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.
