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.

Abstract: A method of calibrating the injectors of an injection system for an internal combustion engine which can compensate for the different flow rates of the injectors fitted in the engine, which are due to the production tolerances of the injectors, in order to re-match the injectors with consequent balancing of the combustion and overall improvement in the performance of the engine. The method is based on the determination of the flow rates of the injectors both with low admissions (idling) and with high admissions (acceleration) by measurement of the torque pulses supplied by each cylinder of the engine with the use of a dynamic torque measurement method.

Abstract: A control device for a coupling electromagnet in particular for a starter motor for a motor vehicle, operable to regulate the speed of engagement of the pinion of the ring gear in such a way as to avoid stresses wear and noise due to excessive speed of engagement in the initial phase of the starting operation. The device operates in a closed loop with a feedback signal generated by an estimator.

Abstract: A method of generating a phase signal over 720.degree. for an internal-combustion engine comprises a multi-point electronic injection system operating sequentially, permitting firing in only some of the cylinders during the starting stage and detecting the angular position in which the first firing occurs.
