摘要： This invention relates to off-road work machines and to controlling the brakes of an off-road work machine and particularly to an arrangement and a method for controlling the working brakes of a hydraulic or electric work machine. It is characteristic of a method according to the invention for controlling the brakes, preferably the working brakes, of a hydraulic or electric work machine (10), (50), in which the hydraulic or electric work machine (10), (50) comprises one or more frame parts (11), (12), (51), (52) and a moving means (13), (53) that the method comprises the steps of: detecting (31), (41) a driver's control action for starting the motion of the hydraulic or electric work machine (10), (50), keeping (32), (42) the brakes of the hydraulic or electric work machine (10), (50) applied and releasing (35), (45) the brakes of the hydraulic or electric work machine (10), (50) when said measured (33), (43) torque value exceeds a predetermined calculatory torque value.

摘要： A control arrangement (20) comprises at least one sensor (7). The sensor (7) is adapted to detect at least one object (9) in an area of at least one predefined sector (10) focused in an area between a control cabin (5) and a boom end (11), and to detect at least one of the following: location information of said detected object at two different time instants, at least, and the speed of said detected object The control arrangement (20) additionally comprises at least one control unit (8) adapted to determine at least the direction of travel of said detected object (9) in relation to the control cabin at two different time instants, at least, on the basis of the detected location information and/or the detected speed of the object (9), and cause a change in the control of a forest machine in response to the detected direction of movement of the detected object (9) being directed towards the control cabin in the area of the sector (10).

摘要： In the present arrangement, a forest machine is controlled, which forest machine includes a body (2), a boom (3) in connection with the body (2) and a tool (4) at the end of the boom (3). A sensor (9) arrangement determines in advance the size of utilisable free space (11A, 11B) starting from the end of the boom (3). This determination consists of determining a direction and a length of the free space (11B). The operation of the tool (4) is allowed into the direction and for the length of the utilisable free space (11A, 11B) determined in advance.
