Abstract
A setpoint torque is determined from a torque factor, a maximum torque and a minimum torque. The torque factor is derived from a pedal value and a rotational speed. The maximum and minimum torques are determined as a function of the rotational speed, a loss torque and engine performance parameters. The loss torque is determined as a function of the rotational speed and the performance parameters.
Claims10
A method for controlling an internal combustion engine, which comprises:
- sensing a pedal value with a pedal value sensor;
- sensing a rotational speed with a rotational speed sensor;
- sensing performance parameters of an internal combustion engine with respective sensing devices;
- deriving a torque factor from the pedal value and the rotational speed;
- deriving a loss torque in dependence on the rotational speed and at least one of the performance parameters;
- deriving a maximum torque and a minimum torque in dependence on the rotational speed, the loss torque and at least one of the performance parameters;
- determining a setpoint torque for a clutch end of a crankshaft from the torque factor, a maximum torque at the clutch end of the crankshaft and a minimum torque at the clutch end of the crankshaft;
- and
- deriving an actuating signal for an actuator of the internal combustion engine from the setpoint torque.
