  • Method for operating a combustion engine in order to prevent excessive switching between at least two modes of operation
    Patent number: 9523314
    Abstract: A method for operating an internal combustion engine of a motor vehicle having a plurality of cylinders all of which are operated in a full load engine mode and some of which are shut down in a partial load engine mode is disclosed, wherein the full load engine mode is switched to the partial load engine mode only if a partial engine operating torque which can be provided by the internal combustion engine in the partial load engine mode is greater than or equal to a target torque set on the internal combustion engine. In order to switch from the full load engine mode to the partial load engine mode, a switch variable determined on the basis of at least one specific parameter of the internal combustion engine and/or of the motor vehicle must additionally be set.
