    摘要: The invention is directed to a brake light switch circuit arrangement having an additional switch S.sub.2 which opens upon actuation of the brake pedal 13 but only after a first switch S.sub.1 closes. The signals from the two switches are processed by a gating circuit (16, 17, 18) to produce brake signals (B.sub.S1 and B.sub.S2) which are to provide a standby idle-running idle-setting signal (LL*) and switch off a driving-speed controller (FGR) via the main computer (30) of the electronic diesel control. In the event that the brake switch S.sub.1 becomes defective and remains closed while overtaking another vehicle, the condition is prevented that the EDC does not reduce the injected fuel quantity to the idling quantity, even though the accelerator pedal is depressed. It is also prevented that, in the event of a fault in the brake switch (S.sub.1) while the accelerator pedal is released, constant vehicle velocity control by the EDC is not switched off.

    摘要: The invention is directed to a system for electronically controlling (open loop and/or closed loop) an internal combustion engine of a motor vehicle. By means of at least one measuring unit at least one signal is generated representing the position of a power-determining component and the measuring unit comprises several sensors. The measuring unit is associated with a power-determining component of the vehicle such as a throttle flap or the control rod and/or accelerator pedal. The sensors are checked with respect to their functional capability by comparing the signal values generated by the sensors to each other with respect to a pregiven tolerance range. When a fault of one or more of the sensors is detected, then that sensor or those sensors which is or are unaffected can be determined.

    摘要: In a supervisory system (FIG. 7) for the accelerator pedal transducer (26) in an electronic engine control (EMS) for a vehicle engine, the output signal (U-FFG) of the transducer (26) is interpreted to show whether or not the transducer is at or close to the idling position. The resulting information is compared with the states of idling and pressure switches (18, 28) which shows whether or not the accelerator pedal (30) is actually at or close to its idling position. A contradiction resulting from this comparison indicates a fault and remedial action can be taken by the EMS, for example, to reduce the engine power to a precautionary value. A contradiction between other comparisons shows that one of the switches (18, 28) is faulty. In the event of the accelerator pedal sticking in a depressed position after the driver has lifted his foot and depressed the brake (FIG. 5) a brake signal (BS) can be passed through a gating circuit controlled by the idling switch signal (FFG-LL) to produce a reaction signal(RS). The EMS processes the latter to reduce the engine power to a precautionary safe value.

    摘要: The invention relates to a system for controlling an internal combustion engine (100), in particular a self-igniting internal combustion engine. A signal (U) for triggering a performance-determining final controlling element (105) is stored in a characteristics map (110) for each of a corresponding fuel quantity (QK) to be injected into the engine. The signal values stored in the characteristics map (110) are then corrected in dependence upon a predetermined relationship of a signal corresponding to the value for the fuel quantity (QK) to be injected and a signal corresponding to the value for the actually injected fuel quantity (QKI).

    摘要: In a method for monitoring an exhaust gas limiting value of an internal combustion engine using an engine controller, the engine controller has at least one exhaust gas sensor, and an error signal is output when the exhaust gas limiting value is exceeded. If the emissions predicted for the present driving state are ascertained with the aid of an engine model and compared to the signal of the exhaust gas sensor or a comparison value for the emission derived therefrom, the prescribed driving cycle may be taken into account when certifying a limiting value monitoring system and a defective system may be reliably recognized in practical operation even in atypical driving states without resulting in erroneous triggering of error signals.

    摘要: In the method for monitoring the sensor device (1), which supplies an analog output signal over a bidirectional output line (3) to an analysis unit (2) for evaluation, a predetermined test signal is applied to a sensor output in a monitoring phase, which is received in the analysis unit (2) and evaluated. In order to initiate the monitoring phase at any arbitrary time without the need of an additional connecting line between the sensor device and the analysis unit, a trigger signal of a predetermined trigger level is transmitted by the analysis unit (2) to the sensor device (1) over the output line (3) and is detected in the sensor device, which generates the predetermined test signal and transmits it to the analysis unit (2) over the bidirectional connecting line (3). A sensor device and connected analysis unit designed to perform this method are also described.
