The disclosure relates to a method for controlling the crane of a working machine by using boom tip control, in which method the crane comprises at least two booms connected to the working machine and each other in an articulated manner, which booms are moved in relation to the working machine and to each other by means of actuators controlled by a control system of the working machine, and in which method the direction and speed of motion of the head of the crane, controlled by the driver applying controls in the working machine, is implemented by applying speeds of the different booms of the crane. In the method according to the disclosure the speeds of different booms of the crane are determined automatically on the basis of at least one of the following factors: positions of the different booms of the crane in relation to the extreme position of their range of motion; the maximum speed of the head of the crane achieved by the crane; maximum force achieved by the crane; location of the head of the crane in relation to the working machine; location of surrounding obstacles in relation to the crane. The disclosure also relates to a system for controlling the head of the crane of a working machine by boom tip control.
