  • METHOD AND OPEN-LOOP AND CLOSED-LOOP CONTROL DEVICE FOR COMPENSATING FOR A CLUTCH TORQUE OF A HYBRID SEPARATING CLUTCH TAKING INTO CONSIDERATION THE ROTATIONAL SPEED OF AN ELECTRIC MACHINE
    Publication number: 20200208690
    Abstract: A method and an open-loop and closed-loop control device for compensating for a clutch torque of a separating clutch located between an internal combustion engine and an electric machine in a hybrid drive of a motor vehicle. The compensation takes into consideration the rotational speed of the electric machine. The rotational speed of the electric machine impacts clutch torque. A compensation factor is calculated, and increases or decreases the necessary clutch torque, causing a corresponding actuation of an actuator to achieve the necessary clutch torque.
