Method for assessing the phase angle of a camshaft of an internal combustion engine, in particular for a motor vehicle |
摘要 |
In order to check the phase adjustment of a camshaft, in which process the present phase angle of a variable phase camshaft can be detected reliably, a first value which corresponds to the actual noise level of the internal combustion engine is determined during a predetermined evaluation window and is compared with a second value, which corresponds to the actual noise level after phase adjustment of the camshaft, with the operation of the phase adjustment of the camshaft being assessed as a function of this comparison.
