Abstract
A method for sampling a sensor that receives a pressure signal, the pressure signal being used as a basis for a pressure signal-based cylinder charge calculation for calculating the fresh-gas charge of cylinders of an internal combustion engine. At the instant at which an intake valve closes at a respective cylinder of the internal combustion engine, the pressure signal is received multiple times in succession in a sampling sequence of individual impulses.
Claims8
A method for sampling a pressure sensor that generates pressure signals (1) and receives pressure signals (1), which are used as the basis of a pressure signal-based cylinder charge calculation for calculating the fresh-gas charge of the cylinder of an internal combustion engine, wherein the pressure signal (1) is received multiple times in succession, using a sequence (10) of samplings, at the instant of the closing (9) of the intake valve in question at the cylinder in question of an internal combustion engine.
