Patent ID: 7416513

Claim:
A self-propelled working machine comprising: ground engaging means that are in drive connection with an engine for propelling the working machine; a desired speed input means having a range of movement for inputting a desired speed; a control unit operable to receive a desired speed signal from the desired speed input means and operable to control an actuator that is influencing the speed of the ground engaging means based upon the desired speed signal, characterized in that the control unit is operable to automatically establish a relation between the desired speed signal and a propelling speed based upon the desired speed signal, characterized in that the control unit is operable to control the actuator to accelerate the working machine beyond the maximal speed designated by the relation established between the desired speed signal and the propelling speed when the desired speed signal corresponds to an acceleration signal, the acceleration signal indicating a position of the desired speed input means within an upper speed portion of a range designated by the relation established between the desired speed signal and the propelling speed.
