Abstract
A method for operating a control unit for an exhaust gas sensor, in particular for a broadband lambda sensor for an internal combustion engine, in particular, of a motor vehicle, or for another sensor device. The control unit is designed to electrically activate the exhaust gas sensor. The control unit is, in particular, implemented in the form of an application-specific integrated circuit (ASIC). The method includes: specifying a measuring sequence and/or a starting point in time, in particular, for an operation of the control unit and/or of the exhaust gas sensor, with the aid of a computing device.
