  • Method for operating a hybrid drive and hybrid drive
    Patent number: 9156199
    Abstract: A hybrid drive includes an electric motor coupled to a hydraulic drive having a double-acting hydraulic piston and a piston rod, and a substantially throttle-less valve for actuating the hydraulic drive, and a control unit for actuating the electric machine. To avoid unnecessary energy consumption, an actuating direction requested by the hybrid drive and a desired actuating force are determined, the valve is switched to a position such that the hydraulic drive is effective in the actuating direction, at least when the actuating force cannot be generated by the electric motor alone, the difference between the force generated by the hydraulic drive and the actuating force is determined, and the electric motor is operated such that the desired actuating force is achieved by adding the force generated by the motor to the force generated by the hydraulic drive, or subtracting the first from the latter.
