Abstract
A method and an arrangement for controlling an internal combustion engine of a vehicle wherein a desired torque value is pregiven, this desired torque value being separated into at least two desired values. The desired values serve to adjust the charge of the internal combustion engine and at least one further power parameter, which effects a rapid torque change. The at least two desired values assume different values at least in one operating state.
Claims10
A method for controlling an internal combustion engine of a vehicle, the method comprising the steps of:
- pregiving a first desired value (Mi-des) for the torque of said engine;
- controlling at least one operating variable of said engine in dependence upon said first desired value (Mi-des) with said operating variable effecting a rapid torque change of said engine;
- pregiving a second desired value (Mi-des-L) for the torque of said engine and adjusting a charge of said engine based on said second desired value (Mi-des-L);
- and,
- pregiving said first and second desired values so that they deviate from each other in at least one operating state of said engine.
An arrangement for controlling an internal combustion engine of a vehicle, the arrangement comprising:
- an electronic control apparatus functioning to determine a first desired value (Mi-des) for the torque of said engine and to form an output signal for at least one operating variable of said engine in dependence upon said first desired value (Mi-des);
- said operating variable effecting a rapid torque change of said engine;
- said electronic control apparatus further functioning to:
- determine a second desired value (Mi-des-L) for the torque of said engine;
- forming an output signal based on said second desired value (Mi-des-L) for adjusting a charge of said engine;
- and,
- pregiving said first and second desired values so that they deviate from each other in at least one operating state of said engine.
