Abstract:
A system for controlling a servo-controlled gearbox (C) fitted in a motor vehicle, comprising:processing means (ECU), sensor means (SENS) operatively connected to the processing means (ECU) for detecting a plurality of physical quantities relating to the operation of the vehicle, and actuator means (AT) operatively connected to the processing means (ECU) for controlling the operation of the servo-controlled gearbox (C); the system being configured so as to detect a plurality of operative conditions of use of the vehicle and to implement different strategies for the control of the servo-controlled gearbox (C) in dependence on the operative conditions of use detected; the processing means (ECU) including reference model means for determining open-loop command signals for said actuator means (AT) on the basis of a predetermined mathematical driving model which sets the behaviour of the vehicle in accordance with a designated profile of the longitudinal acceleration (Ax) of the vehicle, said processing means (ECU) being predisposed for adding to said open-loop command signals closed-loop contribution signals generated by a Linear-Quadratic-Gaussian controller.
