    摘要： The present invention relates to a device and a method for dividing up a total fuel amount, which is to be injected into the combustion chamber of a cylinder during a combustion cycle, into a plurality of injections. To this end, a first fuel amount, which is to be injected during a first injection is determined, a fourth, minimum fuel amount for a third injection is determined, and the total fuel amount minus the first fuel amount is compared to the fourth, minimum fuel amount. When the total fuel amount minus the first fuel amount is greater than or equal to the fourth, minimum fuel amount, the first fuel amount and a second fuel amount, which is to be injected into the combustion chamber of the cylinder during a second injection, are set to zero, and a third fuel amount, which is to be injected during a third injection, is set to the total fuel amount.

    摘要： A method and a device for driving at least one load, in particular a solenoid valve for controlling the injection of fuel in an internal combustion engine. Using at least one switching element, the current flowing through the load is controlled as a function of a control signal. In the presence of at least one safety signal, the load is driven such that it adopts a safe state.

    摘要： A method for controlling a drive unit of a vehicle which allows a comfortable compensation of the torque requirement of ancillary components. In this method, torque losses are compensated in a steady-state manner in an overrun and an acceleration operation. The steady-state compensation of the torque losses in overrun operation is weighted by a first weighting factor. The first weighting factor is raised in a linear manner when the drag torque decreases in amount, until acceleration operation is reached.

    摘要： A method for detecting a malfunction of a sensor measuring a measured quantity is provided, in which a signal-range check for the output signal of the sensor is performed, provided that the measured quantity is within a permissible range. If the measured quantity is outside the permissible range, no signal-range check is performed, but the output signal is used for detecting the measured quantity and for further calculations. The sensor may be, for example, a hot-film air-mass meter. If this is the case, the measured quantity is the drawn-in air mass, and the signal-range check is performed, provided that the engine operating state and thus the drawn-in air satisfies specifiable conditions. In addition to the signal-range check, onboard diagnoses with regard to specifiable plausibility criteria relating to the offset-drift and/or the sensitivity-drift of the sensor may also be performed.

    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.
