Embodiment Construction

[0028] figure 1 In the block diagram of , a calculator 1 is shown, to which the input unit 2 is fed with actually measured command variables, in particular operating parameters (engine speed, load and speed) as well as predeterminable quantities such as sound selection, etc. as an input parameter. The calculator is equipped with a data memory 3 with a database 4 in which signal samples such as four signal samples A, B, C, D and level curves such as level curves F, G with respect to rotational speed, with respect to load The level curves H, K for and the level curve M for speed. Data groups are defined in the index data area 5, in which addressing of signal samples and level curves are stored.

[0029] Taking into account the actual rotational speed, the calculator 1 performs a rotational speed adaptation for one or combined sounds at the calculated step, together with a level adaptation, and outputs the converter with the output unit 6, if necessary via a further amplifier ...

Abstract

The invention relates to a method for synthesizing an engine noise, in particular of an internal combustion engine, wherein the engine noise is generated by at least one electromechanical transducer, in particular an actuator or a loudspeaker, by means of a signal value corresponding to an electrical transducer excitation signal. According to the invention, at least one signal sample (A) having function values (9) is stored in a data memory (3) as a digital data series, such that at signal sample support points (8) following each other in succession at intervals (7), function values (9) are retrievably stored, and such that in accordance with detected and / or pre-definable guide variables as operating parameters of the engine, optionally of a vehicle driven by the engine, function values (9) are retrieved from the data series adapted to the rotational speed and are allocated, level-matched, to signal values in a computing unit (1), and directly or indirectly supplied to the at least one transducer as transducer excitation signals. A device for carrying out the method is also claimed.

Description

technical field [0001] The invention relates to a method for synthetically generating engine noise, in particular of an internal combustion engine, in which at least one electromechanical converter, in particular an actuator or a loudspeaker, is used to generate an excitation signal corresponding to an electrical converter signal value to generate the engine noise. Background technique [0002] Various methods are known for generating a synthetic engine noise, with which in particular the existing engine noise of a motor vehicle can be supplemented in such a way that overall a satisfactory engine sound is produced. For this purpose, an electrical converter excitation signal is generated as a signal value which is fed into at least one installed electromechanical converter, in particular an actuator / actuator or a loudspeaker. [0003] In this method (DE 690 23 133 T3), the existing engine noise is supplemented by the generated additional noise into a pleasing engine sound i...
