摘要：
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.
