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： 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： 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： An electronic control system for an engine of a vehicle is provided with an idling RPM set-point regulator to deliver at its output a nominal idling speed control signal, and a summer for combining the control signal with a modulating error signal which is generated in response to a detection of a defect in a component part of the vehicle. The modulated nominal control signal causes a corresponding change in the normal running of the engine during idling operation or during reduced load thus signalling to the operator a faulty condition. Additional warning means are provided for generating optical warning signals, and means for generating the modulating error signal to be supplied to the electronic control system when a defect occurs in the warning means.

摘要： To allow for apparatus tolerances, aging of equipment, and changes in operation, for example due to changes in temperature, in a closed-loop servo system in which an operator-controlled fuel supply control element (1) provides, via a coupled command control transducer (2), a signal to control a positioning motor (8) which moves a fuel supply control element (9, 29) in accordance with deflection of the operator control panel, a logic and calculating element, in form of a microprocessor (3) is provided, included in the control loop. When the fuel control element, for example a throttle in the induction pipe of an Otto-type internal combustion engine (ICE) or a fuel injection controller of a Diesel engine reaches a predetermined limiting position, for example no-load idling, or full-load wide-open position, and engages a corresponding stop (12, 14; 212, 214), the microprocessor provides a test or monitoring signal which algebraically differs from that which a command signal should have when the fuel control element is at the respective position. The test signal is changed, in linear steps, towards the condition at which an error signal within the servo loop becomes zero or null; the value of the test command signal is stored at that time and used as a compensation or added, algebraically, to the transduced command signal from the command control transducer (2), or interpolated with respect to the other limiting position to derive an interpolation characteristic, thereby modifying the transduced command signal, so that the actual position of the fuel supply control element will be that desired by the operator controlling the operator-controlled controller (1).
