    摘要: A method and an arrangement for the open-loop and/or closed-loop control of the engine power of an internal combustion engine of a motor vehicle is suggested. For checking a safety function, the arrangement intervenes in the fuel metering in the sense of reducing engine speed when an operating condition critical to safety is present. This safety function is triggered in the overrun operation of the internal combustion engine independently of the safety condition and the correct performance is checked. The safety function is detected as being defective when a unlimited metering of fuel takes place in this operating condition when the safety function is triggered.

    摘要: A process for optimizing data and/or program parts for programmed controllers that can be used, e.g., in motor vehicle controllers. In this process, the controller is connected to an external application device via an interface. Changes in the data and/or program parts to be optimized are entered with the help of the application device. This process is characterized in that, at the beginning of the optimizing process, the data and/or program parts are loaded into the data and/or program read-write memory (e.g., RAM) of the controller. In addition, the process is characterized in that specific changes are made in the control program and/or in the memory and/or register locations of the controller to cause the microprocessor of the controller to access the corresponding data and/or program parts in the data and/or program read-write memory (e.g., RAM) instead of accessing the data and/or program parts in the data and/or program read-only memory (e.g., flash EPROM). For a controller to be used in this process, the controller is provided with a decoder circuit that performs a switch when the microprocessor accesses a certain address or a certain address area. As a result of this switch, instead of accessing the data and/or program parts in the data and/or program read-only memory, the microprocessor accesses the corresponding data and/or program parts in the data and/or program read-write memory.

    摘要: A process and a device for air proportioning during idling or overrun mode of operation in an internal-combustion engine are provided. During idling, the internal-combustion engine is regulated to a nominal speed by means of a PI controller (203, 204) and a preliminary air rate control value is determined as a function of temperature, gear position and air-conditioning state of the vehicle. At the same time, the actual air mass or air intake rate (60) is measured and the difference value of the actual air intake rate and the preliminary air-rate control value is stored in a store (304). During overrun, the air-mass throughput of the internal-combustion engine is regulated to this stored value. Furthermore, the control receives a series of auxiliary variables which make it easier to carry out the control as a function of the particular operating mode.
