METHOD FOR CONTROLLING A DRIVE TRAIN OF A MOTOR VEHICLE

摘要

The invention relates to a method for controlling a drive train of a motor vehicle, which comprises a driving motor, an automatic transmission, and an automated clutch disposed in the power flux between the driving motor and the transmission. In order to achieve a low-wear and comfortable trailing throttle operation and a spontaneous transition to the traction mode, it is provided that further trailing throttle downshifts are prevented as soon as the driving speed (v_F) of the motor vehicle has reached or dropped below (v_F <= V_Gr) a previously defined limit speed (v_Gr) for trailing throttle downshifts, or the presently engaged gear (G) corresponds to a previously defined limit gear (G_Gr) for trailing throttle downshifts (G_i = G_Gr), and that after the limit speed (v_Gr) has no longer been met or after the limit gear (G_Gr) has been engaged, a transition into traction mode is prepared in that, as a function of the driving speed (v_F) of the motor vehicle and/or the rotational motor speed (n_M) of the driving motor a current target gear (G_z) and an associated shifting rotational speed (n_s) of an adjustment gear change for the transition into the traction mode is determined.
