An automotive electronic longitudinal dynamics control system of a motor vehicle comprising a powertrain comprising a propulsor electronically controlled by an electronic engine control module and an automatic transmission electronically controlled by an electronic automatic transmission control module to transmit mechanical power generated by the propulsor to drive wheels of the motor vehicle and comprising an automatic gearbox having a plurality of gears with corresponding gear ratios. The electronic automatic transmission control module is designed to output data indicative of a currently engaged gear and a next engaged gear that will be engaged after the currently engaged gear. The electronic engine control module is designed to receive data indicative of an engine torque request and to responsively control the propulsor based on the received engine torque request to cause the propulsor to output an engine torque equal to the requested engine torque. The automotive electronic longitudinal dynamics control system is designed to:

What is described is a control system for controlling the coupling between a driveshaft of a motor vehicle propulsion system and a primary input shaft of a gearbox by means of a servo-assisted friction clutch. A control unit receives at its input signals indicating a command imparted by the driver of the motor vehicle by operating the accelerator pedal in a driving-away or gear-changing manoeuvre, and generates&#x2014;on the basis of a mathematical reference model&#x2014;reference torque request signals indicating the reference torques requested from the driveshaft and from the friction clutch, the said request signals or data varying in time in such a way as to cause synchronization between the angular velocities of the driveshaft and of the primary gear shaft to be reached at the same moment as the difference between the angular accelerations of the said shafts becomes zero.

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.

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.
