Abstract
A method for monitoring a knock control and a device for knock control of an internal combustion engine are provided, in which digital knock data are obtained for the knock control in that the acquisition of data of a knock sensor, converted from analog to digital, is started at a start angle of the internal combustion engine and ended at an end angle. The digital knock data are evaluated so as to detect a malfunction in the acquisition of the digital knock data.
Claims10
A method for monitoring a knock control of an internal combustion engine, comprising:
- obtaining digital knock data for the knock control in that a detection of data of a knock sensor, converted from analog to digital, is started at a start angle of the internal combustion engine and ended at an end angle;
- and
- evaluating the digital knock data in order to detect a malfunction in an acquisition of the digital knock data.
A device for knock control of an internal combustion engine, comprising:
- a data-acquisition device for obtaining digital knock data, which begins an acquisition of data of a knock sensor, converted from analog to digital, at a start angle of the internal combustion engine and ends it at an end angle;
- and
- a monitoring device for detecting a malfunction in the acquisition of the digital knock data and for evaluating the digital knock data.
