Patent ID: 8909445

Claim:
A method for determination of at least one shift point for a gearbox in a motor vehicle, wherein the vehicle comprises an engine, a gearbox connected to the engine, and at least one control unit controlling the gearbox to change gears, the engine driving the gearbox, the method comprising the step of: assisting in automatically determining the at least one shift point through the at least one control unit, each of the at least one shift point being an engine speed at which the gearbox effects a downshift or an upshift, wherein the at least one shift point is automatically determined on the basis of a desired engine target speed ω T and a first engine speed difference Δω TT , which is a difference between a first engine speed at a first time t 1 and said desired engine target speed ω T at a second time t 2 , said first and second times t 1 and t 2 are separated by a time period T, the first time t 1 is: (1) a time at which the engine speed reaches a minimum value in the determination of downshift shift points or (2) a time at which the upshift is completed in the determination of upshift shift points, and the time period T begins at the first time t 1 .
