Method for monitoring a gear-change operation in a motor vehicle provided with a dual-clutch transmission

摘要

The method consists in monitoring a gear-change operation in a motor vehicle provided with an engine (E) whose crankshaft (ES) is connected to a transmission (T) having a gearbox (GS) comprising first and second primary shafts (S1, S2) connectable to the crankshaft (ES) of the engine (E) by respective friction clutches (FC1, FC2) controlled by corresponding actuators (A1, A2), and a secondary or output shaft (SS) connectable to the primary shafts (S1, S2) by gears (G1, G2) defining a plurality of velocity ratios or gears. The method comprises the operation of verifying and validating the detection of the disengagement of the previously engaged gear by detecting the angular velocity (É p,dis ) of the primary shaft (S1) corresponding to the gear to be disengaged, and comparing the detected value of said angular velocity (É p,dis ) with at least one reference angular velocity (É ref ).
