Abstract
In the solution put forth, a pressure level of a pump in a hydraulic transmission system of a hydraulic working machine, or power that is feedable to an electric drive motor of an electric working machine is monitored, and/or the rotation speed at the output of the drive motor of the working machine and the rotation of moving means of the working machine are monitored. The pressure level of the hydraulic power transmission pump, or the power feedable to an electric drive motor, is compared with a lower threshold value to detect a fault situation, and/or the rotation speed at the output of the drive motor is compared with the rotation of the moving means also to detect a fault situation. In case a fault situation is detected, the braking system of the working machine is controlled to apply the brakes.
