Abstract: A control system (190) of a braking device (180) is provided. Said braking device includes at least one braking element (203, 405, 410) adapted to apply a braking action (Tb) to a moving body (140, 205). The control system includes receiving means (310) for receiving an indication of a target value of the braking action to be applied to the moving body, measuring means (320, 330) for measuring an indication of an actual value of the braking action applied to the moving body and driving means (320) for driving the braking element according to a comparison between the target value and the actual value. The measuring means includes sensing means (330) for sensing a warping of at least one part of the moving body and/or of the braking device, and logic means (320) for estimating the actual value according to the warping.

Abstract: The amount of fuel to be injected in each cylinder of a multi-cylinder spark ignition internal combustion engine may be determined with enhanced precision if the fuel injection durations are determined in function of the sensed mass air flow in all the cylinders of the engine, instead of considering only the air flow in the same cylinder.
This finding has led to the realization of a more efficient method of controlling a multi-cylinder spark ignition internal combustion engine and an innovative feedforward control system.

Abstract: A method of sensing the air/fuel ratio in a combustion chamber of an internal combustion engine that may be easily implemented by a respective low-cost device is disclosed.
The device includes a pressure sensor and a learning machine that generates a sensing signal representing the air/fuel ratio by processing the waveform of the pressure in at least a cylinder of the engine. In practice, the learning machine extracts characteristic parameters of the waveform of the pressure and in function of a certain number of them generates the sensing signal.
