Abstract
A method for operating an internal combustion engine includes evaluating a variable which represents the load of the engine. This variable is determined from a torque value measured at an output shaft of the engine. The invention is also directed to an arrangement for operating the engine.
Claims12
An arrangement for operating an internal combustion engine having a transmission, the arrangement comprising:
- means for detecting an input value (MFA);
- a control apparatus for controlling the torque of said engine in dependence upon said input value (MFA);
- a sensor for measuring a torque (meff) at an output shaft of at least one of said engine and said transmission and for supplying a signal indicating said torque (meff);
- said control apparatus including means for receiving said signal;
- said control apparatus further including a torque model operating in dependence upon the measured torque (meff) to determine a variable (rlact) representing the engine load;
- and,
- said control apparatus including means for evaluating said variable (rlact) and said input value (MFA) when controlling said torque.
A method for operating an internal combustion engine connected to a transmission, the method comprising the steps of:
- measuring a torque (meff) at an output shaft of at least one of said engine and said transmission;
- converting said torque (meff) into a variable (rlact), which represents engine load, utilizing a torque model;
- detecting an input value (MFA) for the torque of said engine;
- and,
- determining at least one control quantity of said engine on the basis of said variable (rlact) while considering said input value (MFA).
