摘要： For achieving a highest possible measuring accuracy of a circuit for measuring the internal resistance of an exhaust-gas sensor, a method and a circuit for measuring the internal resistance R1 (10) of an electrochemical cell (12) are provided for determining the temperature of an exhaust-gas sensor, especially of a motor vehicle. The circuit is provided with the objective to improve the control to a constant temperature to therefore also improve the performance of the exhaust-gas sensor. A measurement current I_Mess (20) is applied to the internal resistance R1 (10) of the electrochemical cell (12) and a resulting first voltage is detected. A switchover to a reference resistor R2 takes place from time to time or at regular time intervals. With a switchover to the reference resistor R2, the resulting second voltage is stored and thereafter is applied as a reference value for the measurement of the internal resistance R1 (10). The switchover (18) to the reference resistor R2 takes place, for example, via force/sense lines.

摘要： A method and device for generating a simulated signal relating to a temperature in the exhaust system of a motor vehicle. By means of a characteristic curve or a characteristic diagram, a signal for a steady state exhaust gas temperature is generated as a function of the flow rate of gas through the internal combustion engine of the motor vehicle. This signal is further processed to generate a signal for a rapid portion and to form a signal for a slow portion of the exhaust gas temperature. The signals for the two portions are superimposed with a prescribable weighting to generate a signal for the exhaust gas temperature. The signal for the slow portion can be logically connected, before the superimposition, to a correction value which depends on the speed of the vehicle.

摘要： The invention is directed to a method and an arrangement for monitoring deterioration of lambda probes in the context of a two-probe control. The signal of the lambda probe forward of the converter functions to control the lambda controller and the signal of the lambda probe rearward of the converter influences the lambda controller via an actuating variable and the degree to which the controller is influenced operates for monitoring of the probe forward of the converter. With this method and arrangement, the quality and deterioration of the lambda probe forward of the converter are advantageously detected and, if required, an alarm signal is generated.

摘要： The invention is directed to a method for monitoring the operation of a gas probe, such as a .lambda.-probe for an internal combustion engine. The .lambda.-probe has a probe ceramic (Nernst cell) and a probe heater. The internal resistance (x) of the probe ceramic is measured and a desired value (y) is determined in dependence upon the temperature of the gas to be detected and the heating power of the probe heater. The internal resistance (x) is then compared to the desired value (y) and, when the measured value of the internal resistance (x) exceeds the desired value (y), then a fault signal is generated and/or the fault signal is outputted and/or the fault signal is stored.

摘要： A method and device for monitoring a heating device of a sensor mounted in the exhaust system of an internal combustion engine. In assessing the working order of the heating device, use is made of the fact that a sensor heated by a heating element heats up more strongly than an unheated sensor, and that it is possible to establish, with the aid of the signals output by the sensor, whether the sensor has exceeded its minimum operating temperature. The temperature of the sensor is simulated as a function of internal combustion engine operating characteristics. The working order of the heating device can be assessed with the aid of the simulated temperature and the information as to whether the minimum operating temperature is exceeded.

摘要： The invention is directed to a method for the temperature open-loop control and closed-loop control of exhaust gas probes for mixture control systems having several heatable exhaust gas probes. For this purpose, the temperature of one exhaust gas probe is closed-loop controlled in a control loop and the heaters of other exhaust gas probes are open-loop controlled. The closed-loop controlled exhaust gas probe controls the open-loop controlled exhaust gas probes insofar as the actuating variable of the temperature control loop is used as the output value for the temperature open-loop control of the other exhaust gas probes.

摘要： In a free-wheeling vehicle drive system in which the free-wheeling function is cut in and cut out entirely in response to normal driving operation of acceleration and deceleration, at least the signal corresponding to engine acceleration, which may be provided by the accelerator pedal, is subjected to delay before it may set a flipflop establishing the free-wheeling function. The braking signal, which may conveniently be derived from the brake-light switch, can likewise be advantageously delayed in its resetting of the flipflop in order that brief touching of the brakes should not disable free-wheeling. A more refined system which cuts in free-wheeling only after acceleration of the engine followed by the establishment of an idling condition of the engine can be used without the necessity of providing an overrunning clutch, since the control of a normal clutch connecting or separating engine and drive train can provide free-wheeling. The use of both slow-acting engagement of the clutch and an overriding fast-action engagement, and the taking account of engine speed, engine temperature, downward road slope and rapid changes of position of the accelerator pedal, can provide a sophisticated and nevertheless natural control of free-wheeling over a wide variety of driving conditions.
摘要翻译：在其中随着加速和减速的正常驾驶操作而切换和切断续流功能的再循环车辆驱动系统中，至少可以由加速踏板提供的与发动机加速度相对应的信号，在它可能设置触发器建立续流功能之前经受延迟。可以方便地从制动灯开关导出的制动信号同样可以有利地在翻转触发器时被延迟，以便制动器的短暂接触不应该禁止续流。可以使用更精细的系统，其仅在发动机加速后才能切换自由轮，然后建立发动机的空转状态，而不需要提供超速离合器，因为通常的离合器连接或分离发动机传动列车可以提供续航。使用离合器的慢动作接合和超控快速接合，以及考虑到发动机速度，发动机温度，向下的道路坡度和加速器踏板的位置的快速变化，可以提供复杂而自然的控制在各种驾驶条件下的续航。
