Abstract
A method for limiting an air charge of an internal combustion engine. A maximum permissible pre-controlled charge and an exhaust-gas temperature-dependent delta charge are determined by means of a PI controller. A total permissible charge is determined on the basis of the maximum permissible pre-controlled charge and the exhaust-gas temperature-dependent delta-charge, and the air charge of the internal combustion engine is limited by the total permissible charge.
Claims8
A method for limiting an air charge of an internal combustion engine, the method comprising the following steps:
- determining, using a PI controller, a maximum permissible pre-controlled charge and an exhaust-gas temperature-dependent delta charge;
- determining a total permissible charge based on the maximum permissible pre-controlled charge and the exhaust-gas temperature-dependent delta-charge;
- and
- limiting the air charge of the internal combustion engine by the total permissible charge.
A non-transitory machine-readable storage medium on which is stored a computer program for limiting an air charge of an internal combustion engine, the computer program, when executed by a computer, causing the computer to perform the following steps:
- determining, using a PI controller, a maximum permissible pre-controlled charge and an exhaust-gas temperature-dependent delta charge;
- determining a total permissible charge based on the maximum permissible pre-controlled charge and the exhaust-gas temperature-dependent delta-charge;
- and
- limiting the air charge of the internal combustion engine by the total permissible charge.
An electronic control device configured to limit an air charge of an internal combustion engine, the control device configured to:
- determine, using a PI controller, a maximum permissible pre-controlled charge and an exhaust-gas temperature-dependent delta charge;
- determine a total permissible charge based on the maximum permissible pre-controlled charge and the exhaust-gas temperature-dependent delta-charge;
- and
- limit the air charge of the internal combustion engine by the total permissible charge.
