Optimization of a method for controlling an internal combustion engine

A method for managing an internal combustion engine operating in a predetermined cycle during which cyclical tasks, referred to as segment tasks, are triggered so as to be initiated by a calculator at a predefined moment of the cycle, which moment is referred to as “segment”, in order to determine setpoint values for a forthcoming action, said setpoint values needing to be available before a predetermined angular starting time for application of said setpoints corresponding, the method comprising:

• a) executing a segment task,
• b) determining the difference between the angular starting time for application of the setpoints and the position corresponding to the availability of the setpoint values,
• c) comparing the difference determined in step b) with both a lower difference value and also a greater difference value, the greater difference value being greater than the lower difference value,
• d) modifying the position of the segment for a segment task to be subsequently performed if the difference determined in step b) does not lie between the lower difference value and the greater difference value, the position of the segment being advanced if the difference determined in step b) is less than the lower difference value and said position of the segment being delayed if the difference determined in step b) is greater than the greater difference value.
