Method to determine an optimized shift point, in particular upshift point, for a manual transmission

CURNEWNEWIn order to determine an optimized upshift point, it is proposed that a control circuit, on the basis of a current engine operating point (TQ;N) calculates a new engine operating point (TQ; N) produced when shifting up at approximately the same vehicle speed, wherein the current engine oper...

Zusammenfassung:CURNEWNEWIn order to determine an optimized upshift point, it is proposed that a control circuit, on the basis of a current engine operating point (TQ;N) calculates a new engine operating point (TQ; N) produced when shifting up at approximately the same vehicle speed, wherein the current engine operating point is determined as the optimized upshift point if the calculated new engine operating point is below a preset upper torque limit (TQ_MAX_LIM) and is at the same time above a preset lower engine speed limit (N_MIN_x+1) for the higher gear.
