A method for determination of numbers of gear steps N for a gearbox in a motor vehicle. The vehicle comprises an engine connected to drive, the gearbox. The numbers of gear steps N being the number of downshifts or the number of upshifts which the gearbox respectively effects at an upshift point or a downshift point, wherein a downshift point represents a first engine speed at which the gearbox effects a downshift, an upshift point represents a second engine speed at which the gearbox effects an upshift, and the numbers of gear steps N are determined on the basis of a predicted time period which the engine takes to change from a first engine speed ω1 at a first point in time to a second engine speed ω2 at a second point in time. Also, a system, a motor vehicle, a computer program and a computer program product thereof for the method are disclosed. |
