Abstract

A method for determining a cylinder charge of an internal-combustion engine having valves with a variable valve gear, may include determining a maximum intake valve lift, calculating a standardized cylinder charge relative to at least one of a defined intake spread of an intake valve opening phase and a defined exhaust spread of an exhaust valve opening phase, as a function of the maximum intake valve lift, determining an overlap value, which characterizes an actual overlap of the intake valve opening phase and the exhaust valve opening phase, and determining a corrected cylinder charge based on the standardized cylinder charge and the overlap value.
