Abstract

A method for determination of one or more downshift and upshift points for a gearbox in a motor vehicle. The vehicle includes an engine connected to the gearbox, where a downshift point represents a first engine speed at which the gearbox effects a downshift, and an upshift point represents a second engine speed at which the gearbox effects an upshift. One or more downshift and upshift points are determined relative to an engine target speed which is a desired speed for the engine. A system, a motor vehicle, a computer program and a computer program product thereof perform the method.
