Internal combustion engine e.g. diesel internal combustion engine, controlling method for vehicle, involves determining variable by comparing noise quantity with set point, where quantity is computed by balanced summation of characteristics

摘要

The method involves comparing a noise quantity with a set point, and determining a controlled variable from the comparison, where the noise quantity is computed by a balanced summation of two characteristics. One of the characteristics is determined from a pressure symbol of a combustion chamber or signal of a structure borne noise sensor, where the noise quantity represents intensity noise characteristics of combustion noise. An independent claim is also included for a device for controlling an internal combustion engine.
