A method for controlling an internal combustion engine controlled as a function of an operating-point setpoint, the method includes: determining whether a new operating-point setpoint is received, and if so determining the maximum capacity of the pump based on determined values of rotational speed of the engine, quantity of fuel injected, and fuel pressure in the common injection rail; determining fuel consumption flow rate; subtracting fuel consumption flow rate of the vehicle from the maximum capacity of the pump to obtain the remaining capacity of the fuel pump; determining the difference in fuel flow rate between the current operating point and the operating point of the new operating-point setpoint; and if the remaining capacity of the fuel pump is less than the difference in fuel flow rate, a reduced fuel flow rate gradient setpoint is emitted with the new operating-point setpoint or the quantity of fuel injected is limited.

Method for controlling an internal combustion engine

A method for detecting the malfunction of a software solution configured to generate data representing the instant of interruption of fuel injection of an internal combustion engine. The method comprises acquiring data by a data acquisition device which is connected to a measurement device fixed to an injector body and configured to emit data representing closure instants of an injection nozzle, recording the data generated by the software solution and the data emitted by the measurement device, over a predetermined duration, synchronizing the data generated by the software solution and the data emitted by the measurement device, and comparing the data generated by the software solution and the data emitted by the measurement device, the software solution being considered to be malfunctioning when they do not satisfy predefined criteria.
