Embodiment Construction

[0018] exist figure 1 1 denotes an internal combustion engine, which can drive a motor vehicle, for example, and can be designed as a gasoline engine or a diesel generator. It is assumed below as an example that internal combustion engine 1 is a gasoline engine. Air is fed into a cylinder bank 175 of internal combustion engine 1 via an intake line 25 . The intake air is influenced here by a power-adjustable element 20 , in this example the position of a throttle valve. The position of the throttle valve 20 is influenced here by an engine control unit 30 in particular as a function of the position of an operating element 5 , in particular an accelerator pedal in the case of the motor vehicle considered here. The position of the accelerator pedal 5 is detected by an accelerator pedal model 195 and further transmitted to the engine control unit 30 . through one or more injectors 170 as figure 1 Fuel is injected directly into the combustion chambers of cylinders in bank 175 as...

Abstract

A process and device for internal combustion engine (1) operation requires little supervising cost for a control device (30) of the engine. A regulating parameter for internal combustion engine (1) operation is obtained based on an operational component (5), particular an accelerator pedal operation. A first value for regulating parameters is obtained directly based on the function of the operational component (5). A second value for regulating parameters is obtained based on at least a require for output end parameters of the internal combustion engine (1). When a require for output end parameters different from the first require deduced based on operational component (5) operation is existed, and has right of priority to the first require, the regulating parameter is adjusted based on the second value, otherwise, the regulating parameter is adjusted based on the first value.

Description

technical field [0001] The invention relates to a method for operating an internal combustion engine, in which a control variable for operating the internal combustion engine is obtained as a function of the actuation of an operating element. [0002] The invention also relates to a device for operating an internal combustion engine, which has a determination unit which determines a control variable for operating the internal combustion engine as a function of the actuation of an operating element. Background technique [0003] It is already known to obtain a control variable for operating the internal combustion engine as a function of the actuation of a control element, in particular an accelerator pedal. In this case, the actuation of the accelerator pedal is converted, for example, into a torque request, the so-called driver's desired torque. The driver desired torque is coordinated with other internal and / or external torque requests of the internal combustion engine to...
