METHOD FOR CONTROLLING THE SMOOTHNESS OF GEAR CHANGES IN VEHICLES WITH AUTOMATIC GEARS

摘要

The invention is directed to a method for controlling the gear-shifting comfort in motor vehicles having automatic transmissions. The method provides for pressure controllers for controlling clutches affecting the gear-shifting operations of the transmission. The preset values for the torque and/or the torque curves of the clutches are stored in dependence upon the particular gear-shifting operations and the transmission rpms in a characteristic field. The actual acceleration of the motor vehicle is detected with the aid of an acceleration sensor and a very low desired acceleration is used as a guide quantity for the torque control at the clutches. The preset values for the clutches corrected by this control are stored in the characteristic field.
