An automotive internal combustion engine electronic control unit for performing safety-related functions with a predetermined automotive safety integrity level, including: a microcontroller and an integrated circuit distinct from and communicating with the microcontroller. The microcontroller performs one or more safety-related functions with the same automotive safety integrity level as required to the automotive engine electronic control unit. The integrated circuit performs one or more safety-related functions with an automotive safety integrity level that is lower than that of the microcontroller. The integrated circuit performs, for each performed safety-related function, a corresponding diagnosis function for detecting failures in the performance of the safety-related function. The microcontroller performs, for each performed diagnosis function, a corresponding monitoring function for monitoring performance of the corresponding diagnosis function by the integrated circuit to detect failures that may compromise the diagnostic capability of the diagnosis function.

High diagnosability, quality managed-compliant integrated circuit for implementing ASIL B-compliant automotive safety-related functions

An acquisition system for detecting the angular position of a gas knob of a motorcycle; the acquisition system is provided with: a fixed supporting body; a mobile element, which is mounted mobile in the supporting body; a transmission device, mechanically connected to the gas knob and to the mobile element for transmitting the motion from the gas knob to the mobile element itself; and a main position sensor, which is carried by the supporting body, is coupled to the mobile element for determining the angular position of the mobile element, and is designed to provide two mutually redundant measurements of the angular position of the mobile element.

Method of acquisition and processing of an intake pressure signal in an internal combustion engine without an intake manifold; the internal combustion engine having at least one cylinder that receives fresh air through an intake duct, which is controlled by a butterfly valve and is provided with a pressure sensor connected to an electronic control unit. The acquisition and processing method provides for the following steps: measuring, via the pressure sensor, the instantaneous induction pressure at a plurality of different crank angles distributed over an engine cycle; storing, during each engine cycle, the instantaneous induction pressures in a fast acquisition buffer of the electronic control unit; and determining, at the end of each engine cycle, the mean induction pressure in the engine cycle by calculating a mean of the instantaneous induction pressures previously stored in the fast acquisition buffer of the electronic control unit.

Control method in the case of a fault in an internal combustion engine; the control method provides for the phases of: cyclically checking the correct functioning of a connection between an electronic control unit and an electric drive of an electric actuator coupled to a butterfly valve to control the position of the same butterfly valve, switching off the electric drive in the case of interruption in the connection between the electronic control unit and the electric drive so that the butterfly valve sets itself in a predefined limp-home position, and piloting the engine in the case of interruption in the connection between the electronic control unit and the electric drive to keep the number of revs constant and equal to a predefined emergency value.

A method for detecting the angular position of a gas knob of a motorcycle; the method presents the steps of: detecting simultaneously four mutually redundant measurements of the angular position of the gas knob by means of two mutually independent angular-position sensors forming part of an acquisition system; making a cross comparison two by two between the four measurements for diagnosing any possible malfunctioning of the angular-position sensors; and determining the angular position of the gas knob, using at least one measurement supplied by an angular-position sensor operating properly.

A control method of a fuel feeding system in a bi-fuel internal combustion engine; the feeding system presents: a least a first injector adapted to inject a first fuel type; a least a second injector adapted to inject a second fuel type; a common electronic control unit adapted to drive both injectors; and a switching device, which is controlled by the common electronic control unit and is adapted to electrically connect both injectors to the common electronic control unit by means of at least a first relay adapted to connect/disconnect the first injector to/from the common electronic control unit and by means of at least a second relay adapted to connect/disconnect the second injector to/from the common electronic control unit.

Control method for the mixture ratio in a multi-cylinder internal combustion engine, the control method providing for the following: reading a first real value of the mixture ratio via a master lambda sensor associated with a first cylinder group, reading a second real value of the mixture ratio via a slave lambda sensor associated with a second cylinder group, calculating a first amount of fuel to inject into the cylinders of the first cylinder group to track a mixture ratio target value by using the first real value of the mixture ratio as a feedback variable, calculating the mean of the second real value of the mixture ratio in the detection window, calculating a correction value for the amount of fuel to inject based on the difference between a target value and the mean of the second real value of the mixture ratio, and calculating a second amount of fuel to inject into the cylinders of the second cylinder group by applying the correction value to the first amount of fuel to inject into the cylinders of the first cylinder group.
