Energy storage system for powering vehicle electric user devices

A method for managing the 'stop-and-start' mode in a motor vehicle equipped with an internal combustion engine; the method provides for the 'stop-and-start' mode to be enabled or disabled as a function of a state of charge (SOC) of a battery of the motor vehicle, as a function of a state of motion of a crankshaft of the internal combustion engine and as a function of the electric power consumed overall by the electrical consumers of the motor vehicle.

Method for managing the 'stop-and-start' mode in a motor vehicle equipped with an internal combustion engine

A control system with multiprocessor architecture for an internal combustion powertrain is disclosed. The control system has a computing unit capable of executing both basic control functions of the powertrain and ancillary control functions not directly related to the control of the powertrain. The computing unit comprises a main processor, which is dedicated to executing basic functions for controlling the powertrain, at least one auxiliary processor, which is dedicated to executing ancillary control functions, a number of memories, a series of peripheral devices, at least one peripheral bus connection, to which the peripheral devices are connected, and an intelligent main bus connection of the cross-bar bus type to allow the processors to communicate with the memories and with the peripheral bus connection.

Control system with multiprocessor architecture for an internal combustion powertrain

Engine-control device, in which an internal combustion engine coupled to a transmission group is controlled by a central electronic unit which receives at an input a plurality of information parameters measured in the engine and calculates control signals for operating groups of the engine itself. The device comprises an external processing unit communicating with a control circuit of the transmission group and with the central control unit. The processing unit is capable of being activated by commands originating from the control circuit to modify the control signals, regulating alternately the torque generated by the engine and the speed of rotation of the engine itself.

Electronic engine-control device

The system is used to reduce the possibility of re-creating the conditions in which the phenomenon of detonation is triggered in a combustion chamber of an internal-combustion engine of a power unit which comprises an air inlet manifold, a plurality of cylinders, and an electronic ignition and injection system. The system comprises: means that sense the phenomenon of detonation; means that vary the amount of air channelled towards the combustion chamber; and means connected to the sensing means, for controlling the means for varying the amount of air channelled towards the combustion chamber in order to reduce the possibility of re-creating the conditions in which detonation is triggered.
