    摘要： To increase the resolution of digital words, for example eight-bit words, being supplied via a digital/analog (D/A) converter (2) to a closed control loop, the lowest-order bit (2a) is chopped with a duty cycle, that is, controlled pulse duration/pulse gap ratio, for accurate resolution of the entire word being transmitted. The D/A converter will provide an output of undulating or wavy form, which undulations or waves are averaged or integrated by a low-pass filter (5) or low-pass transmission characteristics of a controller (6) or the overall control loop (4-6-7-8-9-10-11-4) to which the analog signal is applied as a command signal. The system is particularly suitable for accurate control of a fuel supply control element, such as a throttle (9), in the induction pipe of an internal combustion engine using only eight-bit command words, by not transmitting the lowest-order bit in steady-state form but, rather, chopped with controlled duty cycle for conversion of the chopping effect into analog form in the D/A converter (2). The repetition frequency of the pulse duration modulation is suppressed by the low-pass filter or filter characteristics of the control loop.

    摘要： To sense proper operation of a servo control loop including a fuel control pedal (1) which operates a command control transducer (2), e.g. a potentiometer coupled thereto, to provide a command signal to a controller (3) which energizes an amplifier (4) operating a positioning motor (5) which, in turn, changes the position of a fuel control element (7, 207), the instantaneous position of which is fed back to the controller by a position control transducer (6), a signal processing and logic circuit (9, 13) is provided which has the actual fuel supply signal applied thereto. The actual fuel supply signal is evaluated with respect to predetermined limits, for example at a "rest" or OFF position of the fuel control element. This condition can be sensed, for example, based on operating data of the engine, e.g. when a brake light switch is operated, the engine operates above a certain speed, or the vehicle operates at a certain speed, or the like. Additionally, a position sensing switch (8) coupled to the control pedal (1) can be monitored by determining if the output signal from the command transducer is within a limited range when the switch is in a position indicating that the pedal is at, or close to, OFF or "rest" position. By evaluating the actual signal from the respective transducers at predetermined positions of the elements to which they are coupled, e.g. the fuel control element (7, 207) being against an idle or rest stop (16, 216) or the fuel control pedal (1) being at "rest" position, limit switches, particularly in the engine compartment, can be eliminated.

    摘要： The invention is directed to an arrangement for determining the internal resistance of a lambda probe having a positive pole and an internal resistance. A computer includes at least one computer port having a switchable state, a signal input and fixed pregiven values. A supply voltage source having a positive pole and a measurement resistor are also provided. The positive pole of the supply voltage source is connected to the positive pole of the lambda probe via the computer port and the measurement resistor. An analog/digital converter is connected forward of the signal input and the positive pole of the lambda probe is connected directly to the analog/digital converter for applying variable values to the signal input via the analog/digital converter. The computer is adapted to compute the internal resistance of the lambda probe from the variable values applied to the signal input and the fixed pregiven values. A method of determining the internal resistance of a lambda probe is also disclosed.

    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 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.
