Method and device for selecting a starting gear in a vehicle

摘要

A method and a vehicle transmission for selecting a starting gear in a vehicle are provided, the method including steps of measuring a starting gear selection parameter, and selecting a starting gear for the next coming vehicle take-off in dependence of the measured starting gear selection parameter, wherein the starting gear selection parameter is the number of vehicle take offs per time unit. Additionally the parameter can be acceleration in movement of an accelerator pedal being depressed by a driver, accelerator pedal position and clutch wear. Benefits are increased clutch endurance for a vehicle that during at least a period has to perform frequent take-offs and at the same time enhancing take-off comfort for a vehicle that during at least a period goes long-distance.

1. A method for selecting a starting gear in a vehicle, the method comprising:
selecting a normal starting gear as a function of vehicle mass; and after selecting a normal starting gear
measuring at least one starting gear selection parameter, andselecting, via a control unit, a next starting gear for the next coming vehicle take-off in dependence of the measured starting gear selection parameter, the starting gear selection parameter being the number of vehicle take-offs per time unit, the next starting gear being a gear lower than the normal starting gear if the number of vehicle take-offs per unit time exceeds a predetermined number.
