The invention relates to a method for determining a bite point change of a hybrid separating clutch (4) of a hybrid vehicle, which is actuated by a hydrostatic clutch actuator (12), wherein said hybrid separating clutch (4) disconnects or connects an internal combustion engine (2) and an electric traction drive (3). Starting from a position of the hybrid separating clutch (4) in a non-actuated state, the hybrid separating clutch (4) is moved and a basic bite point of the hybrid separating clutch (4) is determined when the hybrid vehicle is started and/or during the operation thereof. In a method, the bite point change between two breathing processes of the hydrostatic clutch actuator (22) is determined from a pressure signal of a pressure sensor (21) and the basic bite point is adapted on the basis of said bite point change.
