  • Patent number: 10302159
    Abstract: The invention relates to a method for determining a bite point of a hybrid clutch in a hybrid vehicle. The hybrid clutch is actuated by a hydrostatic clutch actuator (12) and disconnects or connects an internal combustion engine (2) and an electric motor (3); the bite point is determined by slowly actuating the hybrid clutch (4) starting from a separating position of the hybrid clutch (4), this position being in the non-actuated state, with a defined torque reaction of the electric motor (3) being detected. The invention also relates to a method in which the quality of the bite point is improved, the duration of the bite point adaptation is essentially shortened, the bite point being adapted during the running of the internal combustion engine (2) and when the electric motor (3) is immobile and a torque reaction of the electric motor (3) is validated by the torque reaction of the internal combustion engine (2).
