发明名称 METHOD AND DEVICE FOR DETERMINING THE RESET TIME AND/OR FOR DRIFT COMPENSATION IN A COMBUSTION CHAMBER PRESSURE SENSOR
摘要 In a method for determining the reset time in a pressure sensor that detects the pressure in a combustion chamber of an internal combustion engine and emits a corresponding pressure signal, with the pressure curve in the combustion chamber having at least one high-pressure region the reset time is determined as a function of at least one pressure value detected in the high-pressure phase, so that it is possible, within the sensor, to determine a favorable time at which to reset the drift, based on the pressure range In the method according to the invention, information about the auxiliary rotation speed is determined based on the pressure curve of the compression phase and is then used to generate the reset time, the method entails only slight circuitry-related expense and can therefore be implemented even in an ASIC without complex signal processing, and it functions in almost all known engine operating states.
