A method for the determination of a probe point change and for adaptation of a coefficient of friction of a hybrid separating clutch of a hybrid vehicle

摘要

The invention relates to a method for determining a bite point change of a hybrid separating clutch of a hybrid vehicle. Said hybrid separating clutch (4) disconnects or connects an internal combustion engine (2) and an electric traction drive (3), and the torque (M) supplied by the internal combustion engine (2) and/or the electric drive (3) is conveyed further to the drive wheels (10) of the hybrid vehicle. Said hybrid separating clutch (4) for determining the bite point (TP) moves from an open state into a closed state and a speed gradient (Ga, Gb, Gc) of the internal combustion engine (2) is determined. According to the invention, a very simple adaption of the bite point of the hybrid separating clutch is possible. Said hybrid separating clutch (4) is moved during the operation of the internal combustion engine (2) with constant torque (M) of said internal combustion engine, until a predetermined torque is transmitted by the hybrid separating clutch (4) and the bite point (TP) is corrected in accordance with the speed gradients (Ga, Gb, Gc) of the internal combustion engine (2).
