A METHOD TO DETERMINE AN OPTIMIZED SHIFT POINT, IN PARTICULAR UPSHIFT POINT, FOR MANUAL TRANSMISSION

摘要

Optimized gear shift points for manual transmissions in particular, to a method of determining the up-gear shift point. In order to determine the optimized up gear shift point, the control circuit, the current engine operating point (... TQ _CUR ;. N) on the basis of, roughly at the same vehicle speed than the following new engine operating point resulting from the gear shift to the high gear (... TQ _NEW ;..... N _NEW ) and calculating the calculated new the engine operating point (.. TQ _NEW ;...... N _NEW ) below the preset upper torque limit (TQ_MAX_LIM) for the higher gear than that, and at the same time when the engine speed above the preset lower limit (N_MIN_x + 1), is the current engine operating point is determined as a gear shift point is optimized up by the control circuit.
