A method for adapting a biting point pressure of a hydraulically actuated hybrid disengaging clutch arranged in a hybrid drive train of a motor vehicle between an internal combustion engine and an electric machine includes step by step implementation during driving of the motor vehicle via a plurality of selected engagement operations of the hybrid disengaging clutch with a manipulation of a rapid filling routine. Proceeding from an initially stored biting point pressure, a setting pressure, which is reduced relative to a subsequent rapid filling routine, is incrementally increased step by step. An actual value, which is set in each case for a test parameter, is detected until the actual value corresponds to a setpoint value. A change in the transmission of torque of the hybrid disengaging clutch is derivable via the actual value.
