Abstract: A method for sharing data between a microcontroller and a plurality of driving circuits of actuators is disclosed. A microcontroller is provided with a microsecond bus and a plurality of chip-select outputs. A plurality of driving circuits have input pins for data signals received from the microcontroller through the microsecond bus. Each of the driving circuits has an input pin receiving a signal from a chip-select output of the microcontroller and at least two configuration pins connected to the ground voltage or to a supply voltage. A data frame signal is sent on the microsecond bus. Each of the driving circuits is supplied with a portion of the data frame signal as a function of the chip-select output of the microcontroller and as a function of the voltage connection of the at least two configuration pins.

Abstract: Technical solutions are described for measuring fuel injection to an engine of a vehicle. For example, an engine control unit (ECU) that controls the operation of the engine, is equipped with a first direct memory address channel to store rail pressure values that are received from the engine in a first buffer. The ECU further includes a second direct memory address channel configured to copy a first subset of the rail pressure value from the first buffer to a filter module in response to an angle-based interrupt request. The ECU further includes a third direct memory address channel configured to copy filtered pressure values from the filter module to a second buffer. The ECU also includes a processor that computes a pressure drop based on the filtered pressure values from the second buffer, and compute a quantity of fuel injected into the engine based on the pressure drop.

Abstract: A clutch adapted to transmit the motion from a driving shaft to a driven shaft, having an axis of rotation coaxial to the driven shaft and comprising, a ring gear, a first bell integral in rotation with the ring gear and coaxial to the axis of rotation, an axially fixed hub internal to the first bell and coaxial to the axis of rotation, an axially movable pressure assembly including a disk-pusher element, a disk pack, a plurality of elastic elements, and a centrifugal assembly. The clutch comprises at least one first clearance-recovery device of a unidirectional type, adapted to limit the separation of the disk-pusher element from the axially fixed hub and from the disk pack, and a second clearance-recovery device of a unidirectional type, adapted to enable an axial movement of the centrifugal assembly only towards the disk-pusher element.
