摘要： The invention is directed to a diagnostic arrangement for a potentiometric, electrical exhaust-gas probe for the control of combustion processes with a periodic change of the composition of the combusting air/fuel mixture between oxygen deficiency and oxygen excess. The exhaust-gas probe is heated by an electric heater and outputs a probe signal when the exhaust-gas probe operates without fault which changes between a first region of high signal values (oxygen deficiency) and a second region of low signal values (oxygen excess) with the first region and the second region being separated by a third region of values. A fault announcement is outputted when the probe signal lies within the third region longer than a pregiven longest duration. A fault announcement is also outputted when changes of the current supplied to the electric heater occur within the pregiven longest duration and when the probe signal has temporarily left the third region of values after the change of the heater current.

摘要： A mixture controller for adjusting an output value, which is outputted by a PI two-point controller, to control the air/fuel ratio of a mixture supplied to an internal combustion engine to a pregiven value. The engine produces an exhaust-gas flow during operation and has an oxygen probe mounted in the exhaust-gas flow. The mixture controller continuously detects the signal of the oxygen probe to obtain sequential measurement values of the signal. A check is made as to whether a currently detected measurement value of the signal has crossed over a threshold value in the lean or rich direction compared to the previously detected measurement value of the signal. The output value is changed when a crossover of the signal in the lean direction is present by shifting the output value with a large step via a P-jump in the rich direction and starting an integration of the output value in the rich direction from a previous lean direction. The output value is also changed when a crossover of the signal in the rich direction is present by stopping the integration of the output value in the rich direction and starting an integration in the lean direction after a pregiven delay time has elapsed. The operation of the mixture controller is returned to checking after the output value has changed. A return of the operation of the mixture controller to the checking operation is inhibited until an inhibit time has elapsed.

摘要： The invention is directed to a method for determining the particular current value of at least one control parameter for a lambda control of an internal combustion engine which provides a shift to make the fuel mixture lean or a shift to make the fuel mixture rich in dependence upon the operating state of the controlled engine. The method includes the steps of: determining a base value for the control parameter in dependence upon the current value of at least one pregiven operating variable as the current value applies for a control with a minimal discharge of toxic gas during steady-state operation of the engine; and, modifying the base value with a transition variable having a value decaying as a function of time when changes in the operating state of the engine occur. The method of the invention affords the advantage that the control parameter does not have a value which was applied for a minimum discharge of toxic gas for a typical operation sequence at steady-state or transient operation; instead, for steady-state and transient operations, optimized values are available. In this way, a discharge of exhaust gas is obtained which is lower compared to possibilities which have existed up until now.
摘要翻译：本发明涉及一种用于确定内燃机的λ控制的至少一个控制参数的特定电流值的方法，所述控制参数提供了使燃料混合物偏离或使燃料混合物富集的变化受控发动机的运行状态。该方法包括以下步骤：根据至少一个预定操作变量的当前值来确定控制参数的基值，因为当前值适用于在稳态运行期间具有最小排放有毒气体的控制发动机; 以及当发生发动机的运行状态发生变化时，用具有衰减作为时间的函数的值的转换变量来修改基值。本发明的方法提供的优点是，在稳态或瞬态操作中，控制参数不具有用于典型操作顺序的有毒气体的最小排放的值; 相反，对于稳态和瞬态操作，可以使用优化值。以这种方式，获得与迄今为止存在的可能性相比较低的废气排放。

摘要： The invention is directed to a method for checking the aging condition of a catalyzer by utilizing a lambda probe rearward of the catalyzer. For a transition from lean to rich which takes place within a pregiven time span, a check is made if an overshoot of the probe signal occurs which exceeds a pregiven amplitude. A conclusion is drawn as to the aging condition of the catalyzer from an overshoot when the latter occurs. Transitions between lean and rich and vice versa take place especially during the transition from overrun operation to controlled operation of the engine. Transitions of this kind have large swings of the signals of the lambda probes and this permits reliable measurements. In contrast, conventional methods operate exclusively when the engine to which the catalyzer belongs is lambda controlled. The relatively small signal amplitudes occurring thereby lead to a signal/noise ratio which is considerably poorer than in the methods according to the invention.
摘要翻译：本发明涉及一种通过利用催化剂后面的λ探针来检查催化剂的老化状态的方法。对于在预先设定的时间范围内发生从瘦到丰富的过渡，如果发生超过预先设定的幅度的探头信号的过冲，则进行检查。从后期发生时的催化剂的老化状况得出结论。精益和富余之间的转变反之亦然，特别是在从超速运行过渡到发动机的受控操作过程中。这种转换具有λ探针信号的大的波动，这样可以进行可靠的测量。相比之下，当催化剂所属的发动机是λ控制时，常规方法仅仅是操作的。由此产生的相对较小的信号幅度导致与根据本发明的方法相比差的信噪比。

摘要： The invention is directed to a method for lambda control of an internal combustion engine having a catalyzer and a measuring probe arrangement in front of the catalyzer for emitting a measuring signal and a testing probe arrangement behind the catalyzer for emitting a test signal. The method includes the steps of: forming a ratio between the measuring signal and the test signal at pregiven operating conditions; evaluating said ratio as an estimating quantity for the conversion rate of the catalyzer; and, modifying output values of control parameters in a pregiven controlled manner on the basis of the instantaneous values of said ratio, said output values being applicable for controlling an internal combustion engine having a new catalyzer. This method affords the advantage that it evaluates a catalyzer with the aid of the above-mentioned ratio value and controllably modifies values of control parameters in dependence upon the evaluation ratio. This leads to an especially stable control with low toxic gas discharge.

摘要： In a method for lambda value detection, the voltages of the loaded and the unloaded lambda sensor are detected and the internal resistance of the sensor is calculated from these values with the aid of the known value of the load resistance. The value of the internal resistance and the respective value of the voltage of the sensor in the unloaded state serve as input variables for a characteristic field, in which lambda values dependent on values of the internal resistance and of the voltage of the sensor in the unloaded state are stored. The method of the invention affords the advantage that lambda values can be measured very accurately even in the strongly temperature-dependent rich branch of a sensor, for example, of a sensor of the Nernst type. The values thus detected can be indicated by a measuring device or they can be used for exhaust gas control, for example in warming-up or at full load.

摘要： To reduce disturbance and interference signals, and particularly recurring disturbance signals due to vibration or out-of-round conditions of rotating elements coupled to a speed transducer, a low-pass filter (11) is connected to the speed transducer and, in addition, a high-pass filter (12) which, however, is disconnected upon sensing that the speed of the wheel or of the vehicle is below a predetermined limit, or that the anti brake-lock system unit (13) has responded. Thus, disturbance signals, and particularly periodic disturbance signal which might cause oscillatory conditions to arise in the filter and transducer circuitry, are effectively suppressed. To further increase the reliability of response, the output from the filter circuits is connected to threshold circuits with a variable threshold level in which comparators compare a peak signal with a weighted, then existing signal, so that the comparison level threshold is continuously shifted based on previously occurring peaks, so that disturbance signals are reliably excluded from affecting signal processing within the anti brake-lock system unit (13).

摘要： In the tractor vehicle a current measuring resistor is interposed in the line supplying current to a coupling connector terminal to which the antilock system of a trailer equipped with such a system is connected for its power supply. A resistor load is connected to this power supply line through a switch that is closed when no trailer is coupled but is held open when a trailer is coupled. The current through the current measuring resistor either flowing through the resistor load or through a normally functioning antilock system of a trailer causes operation of a threshold switch to energize the brake antilock system of the tractor vehicle. A relay controlled by a starting circuit controls the application of the supply voltage to the trailer brake antilock system which is arranged to be tripped by a malfunction of the antilock system that may occur after a brief starting period, in which case the reduction of current in the supply line also results in putting the antilock system of the tractor out of operation. Thereafter, the antilock systems cannot be put into operation again until the voltage supply to the trailer is interrupted and reapplied to restart the antilock system of the trailer.
