Abstract:
A method for determining a starting gear step for a vehicle having a stepped variable transmission, said transmission having at least two gear steps, said method comprising the following steps:connecting the stepped variable transmission, said transmission having an input side and an output side, on the input side with an engine that produces an engine torque, by an optionally engageable starting clutch, and operatively on the output side with input gears of the vehicle, to transmit a traction; determining the starting gear step by an electronic control device according to at least a vehicle mass (8) and a second variable (6), said second variable dependent on a driving mode comprising a climbing resistance of the vehicle; constantly determining during a drive an actual value of the second variable (6) from the vehicle mass (8), an actual traction (4), and an actual vehicle acceleration (2) resulting therefrom.
