Abstract
A method of starting or holding a mobile vehicle and, in particular, a working machine. The method determines whether the vehicle is rolling backward on an inclined surface and, as a function of that knowledge, the rotational speed of the drive engine is increased, or a downshift by one gear is carried out in the transmission.
