Abstract: The system comprises control devices (CS) arranged to implement a stop-start function in which, during a stop stage, the internal combustion engine (1) is disconnected from the electric machine (4) and from the transmission system (2) and is switched off in first predetermined operating conditions of the vehicle (V) and then, in a subsequent start stage, is automatically restarted by an electric machine (4), operating as a motor, and is then-reconnected to the transmission system (2).

Abstract: An internal combustion engine (E) has associated control devices (ECU, GSCU, SCU) for controlling the engine in a manner such that the engine delivers a driving torque (CM) which is variable in dependence on predetermined measured parameters, in particular on the position (&agr;) of the accelerator pedal (AP), and sensors (S1, S2) for detecting the position (&agr;) of the accelerator pedal (AP), and the rate of rotation (&ohgr;M) of the shaft (M) of the engine (E) or the forward speed (v) of the motor vehicle, respectively.

Abstract: A first clutch and a second clutch, which are operable selectively, control the coupling of the rotor of a reversible electrical machine with the transmission and with the internal combustion engine, respectively. A control system is provided for implementing a stop-start function in which, in a stop stage, the internal combustion engine is disconnected from the electrical machine and from the transmission and is switched off, in first predetermined operating conditions of the vehicle and then, as a result of the occurrence of second operating conditions, such as a command imparted by the driver, in a subsequent start stage, is automatically restarted by means of the electrical machine operating as a motor, and is then reconnected to the transmission. The system is characterized especially by particular methods of controlling the clutches and the electrical machine during the start stage.

Abstract: A system for controlling a servo-controlled gearbox (C), configured so as to use gear-shifting strategies similar to those used by a human driver so as to improve the driving sensation experienced by the driver. The control system uses a plurality of sensors (SENS) disposed in the vehicle for detecting the various operative conditions and a system of rules (a rule-based system) for implementing the strategies provided for.
