Abstract: A prime mover has an internal combustion engine and a motor generator. A setpoint of a torque depends on a variable representing the wish of an operator of the prime mover and on operating variables of the internal combustion engine. Actuating signals for actuators of the internal combustion engine depend on the setpoint of the indicated torque. An actuating signal for the motor generator which is arranged on the output shaft of the internal combustion engine depends on the setpoint of the torque.

Abstract: 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.

Abstract: 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.
