Abstract:
1. A method for controlling a hydraulic drive system, which comprises a closed hydraulic circuit with a hydraulic pump and a hydraulic motor, comprising: providing by a control circuit in dependence on a desired speed of the hydraulic motor (n at least one of limiting and reducing by a superordinate control module ( wherein the specified power value of the hydraulic pump is a maximum specified output power of the hydraulic pump, the current power value of the hydraulic pump is a current output power supplied by the hydraulic pump, the specified power value of the hydraulic motor is a maximum specified output power of the hydraulic motor recirculated to the hydraulic pump, and the current power value of the hydraulic motor is a current output power of the hydraulic motor recirculated to the hydraulic pump, such that the power provided by the hydraulic pump does not exceed the maximum specified output power of the hydraulic pump and that a braking torque provided by the hydraulic motor is less than the maximum specified output power of the hydraulic motor, and wherein the actuating signal (I) is at least one of limited and reduced on the one hand in dependence on a matching of a current pump power value (P
