ABSTRACT:
A processing device capable of starting the sequence of the speed change operations automatically in the gearbox of a vehicle, such as the automatic transmission of a truck. A first comparator (302) compares the data received from a gearbox condition detecting device (500) and that received from a speed ratio selection device (200). In the event of a difference, the comparator (302) sends to a gearbox control device (400) either a pulse for increasing by one speed ratio, or a pulse for decreasing by one speed ratio.
