Abstract
A method for controlling a working machine provided with a bucket as a work implement by which a lifting force can be exerted on an object such as a gravel pile, and at least one ground engaging element by which a traction force can be exerted on the same object is provided. A state input indicative of a current bucket state is received, the bucket height being a parameter of the current bucket state, determining a lifting force eliminating speed of the power source ('LFES') at the current bucket state, the LFES being the speed at and above which no lifting force could be achieved considering a reaction force acting on the bucket caused by the traction force, and the speed of the power source is controlled not to reach the LFES in order that at least some lifting force could be achieved.
