Abstract
The invention relates to a method for determining a starting gear step for a vehicle with a multi-speed stepped variable transmission, wherein the starting gear step is determined by an electronic control device which is dependent on the vehicle mass; and a second variable which depends on the vehicle state is determined from the vehicle mass, the current traction and the current vehicle acceleration resulting therefrom.
