A method of controlling exhaust gas recirculation in the internal combustion engine includes: sensing one or more sensing signals indicative of operating conditions of an internal combustion engine, producing, as a function of the sensing signal or signals sensed, an exhaust gas recirculation control signal for controlling exhaust gas recirculation in the internal combustion engine, producing, e.g., via a 'virtual' sensor including a neural network, a particulate size distribution signal indicative of the particulate size distribution in the exhaust of the internal combustion engine, correcting the exhaust gas recirculation control signal as a function of the particulate size distribution control signal, thereby producing a corrected exhaust gas recirculation control signal, and controlling exhaust gas recirculation in the internal combustion engine as a function of the corrected exhaust gas recirculation control signal.

A method for control of an internal combustion engine includes generating, with a microelectromechanical system (MEMS) accelerometer, an acceleration signal representing vibrations of the internal combustion engine. An engine crank angle signal is generated based on the acceleration signal. The engine crank angle signal is compared with a target value. The internal combustion engine is adjusted based upon the comparing.

A method of detecting during a combustion cycle a peak value of pressure in a cylinder of an internal combustion engine includes providing and installing on the engine body an accelerometer that generates an acceleration signal representing vibrations of the engine body. The acceleration signal is filtered by comparing the band-pass filtered replica of the acceleration signal to a threshold. When the threshold is surpassed, a pressure peak is detected and flagged.

A control system for an electromechanical-braking system provided with actuator elements configured to actuate braking elements for exerting a braking action has a control stage for controlling the braking action on the basis of a braking reference signal. The control stage comprises a model-based predictive control block, in particular of a generalized predictive self-adaptive control type, operating on the basis of a control quantity representing the braking action. The control system further has: a model-identification stage, which determines parameters identifying a transfer function of the electromechanical-braking system; and a regulation stage, which determines an optimal value of endogenous parameters of the control system on the basis of the value of the identifying parameters.
