Abstract:
The present invention relates to a method for determination of one or more shift points for a gearbox in a motor vehicle which comprises an engine connected to, in order to drive, said gearbox, where a shift point represents an engine speed at which said gearbox is adapted to effecting a downshift or upshift, said one or more shift points are determined on the basis of an engine target speed ωT and a first engine speed difference ΔωTT, said target speed ωT is a desired speed for said engine, said first engine speed difference ΔωTT is a difference between a first engine speed at a first time t1 and said target speed ωT at a second time t2, and said first and second times t1 and t2 are separated by a time period T. The invention relates also to a system, a motor vehicle, a computer program and a computer program product thereof.
