摘要： In a method for monitoring the functionality of a temperature sensor that can deliver an electrical signal as a function of the measured temperature and is disposed, in particular, in the cooling water circuit of an internal combustion engine, the persistence of the temperature sensor in the high signal range is made possible by a method encompassing the following steps: Characterizing the sensor as possibly faulty if the sensor indicates, upon engine shutdown, at least a maximum value of the cooling fluid temperature; determining a first gradient of the cooling fluid temperature, measured by the possibly faulty sensor, up to a first point in time after engine shutdown, and characterizing the sensor as fault-free if the gradient exceeds a minimum value; determining a second gradient of the cooling fluid temperature, measured by the possibly faulty sensor, between the point in time and a point in time after engine shutdown, and characterizing the sensor as fault-free if the second gradient exceeds a minimum value; determining the cooling fluid temperature measured by the possibly faulty sensor at a point in time after engine shutdown, and characterizing the sensor as fault-free if the cooling fluid temperature falls below a maximum value.

摘要： A method for checking at least three sensors which detect a measured quantity in the area of an internal combustion engine. A measure of the sensor signal of the particular sensor to be checked is compared to a reference signal which is obtained from at least one part of the sensor signals of the sensors to be checked. A sensor is recognized as defective on the basis of a comparison of the measure for the sensor signal with the reference signal. The reference signal is formed, for example, from a mean value of a measure of the sensor signals of at least one part of the sensors to be checked, the individual sensor signals being weighted using correction factors in forming the mean value. The sensors are temperature sensors or pressure sensors, for example, which may be situated in an intake area of the internal combustion engine, on the internal combustion engine itself, in an exhaust area, and/or in an exhaust gas treatment system.

摘要： A method for monitoring motor vehicle systems that include mechanical components and at least one control device detects, in a first step, input signals and output signals as quantitative signals that characterize the operating behavior, assigns discrete qualitative values to value intervals of the input signals and output signals, which are established using a particular sequence of threshold values. A change to one of the qualitative values is recognized as an event, and consecutive events are stored as an event sequence. The event sequence is compared with a model of the normal behavior of the motor vehicle system, in particular a model composed of all event sequences of the proper operation of the motor vehicle system. If there is a match, it is assumed that the motor vehicle system is operating properly. If there is no match, erroneous operation is assumed.

摘要： The invention relates to devices and methods for reducing the contamination of a sensor with which a sensor or sensor element—preferably a hot film air-mass meter—is deactivated when a software function integrated in the electronic control unit detects a possible contamination or a media carry-in. The sensor is deactivated using a high-side switch in the voltage supply or a low-side switch in the ground connection, wherein the media carry-in detection and the switch control are carried out by the control unit or an evaluation unit in the sensor. After the sensor is deactivated, a substitute signal is optionally generated that replaces the missing output signal of the sensor.

摘要： A method for monitoring a microprocessor and a circuit arrangement having a microprocessor are described. A microprocessor is monitored using an assigned watchdog. The watchdog monitors whether reset pulses are received within a time interval of predetermined duration. If the reset pulse is received, the time interval is reset and restarted. If reset pulses are not received, a reset of the microprocessor is initiated. In suitable operating phases of the microprocessor, a check function of the watchdog is activated. During the execution of the check function, first a reset of the watchdog is executed and then a sequence of waiting loops, whose duration is greater than the duration of the time interval of the watchdog, is executed.
