摘要： A circuit configuration for generating a virtual ground includes a micro-controller, an analog circuit and a read-only memory. A pulse-width modulated signal, which is output by the micro-controller, is converted, by using the analog circuit, into the virtual ground as a common reference potential of an exhaust probe which operates according to the principle of the galvanic oxygen concentration cell with a solid electrolyte. The actual value of the virtual ground is read into the micro-controller through the use of an A/D converter and is compared with a predefined setpoint value. The potential value of the virtual ground is then controlled on the basis of the difference value. An exhaust probe configuration is also provided.

摘要： A circuit configuration for controlling a pump current includes a microcontroller, an analog circuit and a read-only memory. A pulse-width modulated signal, which is output by the micro-controller, is converted, by using the analog circuit, into the pump current for a pump cell of an exhaust probe which operates according to the principle of the galvanic oxygen concentration cell with a solid electrolyte. A pump current actual value is determined from a voltage drop across a measuring resistor, and a pump current setpoint value is determined from a voltage difference between an actual value of a Nernst voltage in the corresponding measuring cell and a predefined setpoint value. An exhaust probe configuration is also provided.

摘要： A method for monitoring the operation of sensors in an internal combustion engine includes providing reference values from output signals from a sensor. A sliding average (comparison value) is calculated from a relatively large number of reference values. The operation of the sensor is diagnosed as a function of the amplitude distribution of the reference values about the comparison value. If a malfunction is found, a fault message is transmitted to the driver and reversionary running of the internal combustion engine is started. An electric controller operating in accordance with the sensor is also provided.

摘要： A method for determining a closing time of a valve having a coil drive, in particular a direct injection valve for an engine of a motor vehicle, has the steps: (a) switching off a current flow through a coil (L_inj) of the coil drive, so that the coil (L_inj) is depowered, (b) capturing a time curve (110) of a voltage induced in the non-powered coil (L_inj), wherein the induced voltage is generated by decaying eddy currents in a magnetic circuit of the coil drive and by a motion of the armature relative to the coil (L_inj), (c) evaluating the captured time curve (110) of the voltage induced in the coil (L_inj), and (d) determining the closing time based on the evaluated time curve (110). A corresponding device and a computer program for determining the closing time of a valve with a coil drive can be provided accordingly.
