A method for controlling an internal combustion engine includes the determination of a measured value of an actual torque. An estimated value of the actual torque is determined as a function of operating variables of the internal combustion engine. A correction value is calculated as a function of the estimated value and the measured value of the actual torque. A setpoint value of the torque that is to be set by the air mass flow rate is calculated as a function of a pedal position, which is determined by a pedal position sensor, and of at least one further operating variable, and correction as a function of the correction value. An actuator signal for an actuator element of the internal combustion engine is determined as a function of the corrected setpoint value of the torque.

Method for controlling an internal combustion engine

A method of determining a mass of fuel to be introduced into a suction pipe or into a cylinder of an internal combustion engine precontrols a basic injection time constituting a basic injection quantity, through a prescription of a lambda set point. The lambda set point is determined by a coordinated calculation through selecting a minimum and a maximum from a multiplicity of different lambda requirements which are derived from operating states of the internal combustion engine. Different priorities are allocated to the various lambda requirements.
