The system is operable to control a robotized gearbox (GS) which includes control levers (L1, L2) which can be displaced along at least one working line (1-4) along which a plurality of nominal operating positions are defined which correspond to the speed ratios or gears (I-VI; R) and to a neutral position (N). <??>The control system includes electro-mechanical actuators (A1, A2) coupled to the control levers (L1, L2) and operable to displace them along the said at least one working line (1-4), and an electronic control unit (ECU) operable to control these actuators (A1, A2) to operate in a predetermined manner, so as to position the control levers (L1, L2) selectively in one of the operating positions. <??>The control levers (L1, L2) have associated sensors (PS1, PS2; IS1, IS2; TS1, TS2) operable to supply the control unit (ECU) with signals which together indicate that the levers (L1, L2) have reached predetermined positions along the said at least one operating line (1-4). <??>The control unit (ECU) is operable to carry out a process of learning and memorizing the actual engagement positions of the speed ratios or gears, which makes it possible to eliminate any operations for calibrating or adjusting the positions of the gears at the end of the assembly line. <IMAGE> |
