Abstract
A control and evaluation unit for the operation and evaluation of at least one sensor, in particular for the operation and evaluation of at least one lambda probe of an internal combustion engine, signal inputs being disposed for the reception of analog measured signals of the at least one sensor, received analog measured signals being digitized by way of an analog/digital converter, a signal transfer unit, by way of which digitized signals are transferred to a calculation unit, being disposed, and provision being made in particular that the signal inputs are switchable by way of a multiplexer.
Claims13
A control and evaluation unit for the operation and evaluation of at least two sensors, comprising:
- signal inputs of the at least two sensors to receive analog measured signals of the at least two sensors;
- an analog/digital converter to provide digitized signals of the received analog measured signals;
- a signal transfer unit to transfer the digitized signals to the calculation unit;
- and
- a multiplexer to switch the signal inputs of the at least two sensors.
