    Abstract: A method of controlling the fuel rail pressure of a fuel injection system of an internal combustion engine is disclosed. A failure condition of a fuel rail pressure sensor is detected. A fuel rail pressure target value and an injector fuel output target value are determined on the basis of an internal combustion engine operating condition. A fuel pump output target value to be supplied into the fuel rail is determined. The fuel pump is driven in order to provide the fuel pump output target value. The fuel pump output target value is determined on the basis of the injector fuel output target value, and the fuel injector is energized for an energizing time target value determined on the basis of the fuel rail pressure target value and the injector fuel output target value.

    Abstract: A method of determining the timing and quantity of fuel injection to operate an internal combustion engine is disclosed. While operating the fuel injector to perform a fuel injection; a signal of a fuel pressure within the fuel rail during the fuel injection is sampled. The signal is used to determine first and second integral transforms yielding as output a value of first and second functions having as variables the fuel rail pressure drop caused by the fuel injection and the timing parameter indicative of the instant when the fuel injection started. Values of the first and second functions are used to calculate a value of the fuel rail pressure drop caused by the fuel injection and a value of the timing parameter. A value of a fuel quantity injected by the fuel injection is calculated as a function of the value of the fuel rail pressure drop.

    Abstract: Methods and apparatus are provided for a high current control strategy and a low current control strategy using fixed threshold values and variable threshold values. An electrical quantity related to an electrical current which is to be switched is received on an input. The electrical quantity related to the electrical current is compared with a predefined first fixed threshold value in a first comparator for determining a first logical state. The electrical quantity is compared with a first variable threshold value in a second comparator for determining a second logical state. The electrical current is switched between an ON state and an OFF state in response to a switching signal on an output terminal when the electrical quantity of the electrical current meets the first variable threshold value. The first logical state, the second logical state and the switching signal provided at the output terminal vary the first variable threshold value.
