    摘要： A method for controlling an injection of fuel in an internal combustion engine in which steady-state optimum injection parameters, in particular the start-of-injection angle, is corrected for non-steady-state operating phases. The correction is carried out by a transmission element to which the driver's request is fed as an input and correction parameters are determined therefrom. Using the correction parameters, fuel injection parameters obtained from a characteristic diagram that is optimum for steady-state operating conditions are corrected. In this manner, the behavior of the internal combustion engine is improved for non-steady-state operating phases.

    摘要： A method and a circuit configuration for gear detection in a motor vehicle transmission detect a signal corresponding to an input rpm and a signal corresponding to an output rpm of the transmission. A quotient of the output rpm to the input rpm is formed. A gear that has been engaged is detected from this quotient and from a known gear ratio of the transmission. A variation over time of the ratio of the output rpm to the input rpm of the transmission is ascertained and compared with a limit value. If the limit value is exceeded, a determination is made that no gear has been engaged.

    摘要： A process for suppressing torque jumps during operation of an internal combustion engine prevents torque jumps when switching pilot injection (pre-injection) on and off in a diesel internal combustion engine by forming a difference between a predetermined total quantity of fuel to be injected and a pilot quantity to be injected by a pilot injector and acting upon the difference with a correction factor that produces torque balancing. A difference quantity which is corrected in this manner represents a main injection quantity.

    摘要： A method for controlling an exhaust gas recirculation device in an internal combustion engine includes calculating an actual value of an exhaust gas recirculation rate from a current air flow rate measured by an air flow rate meter and a theoretical air flow rate that would result without exhaust gas recirculation. A difference is formed from a desired value stored as a function of load and from the actual value for the exhaust gas recirculation rate. The difference is supplied to a controller which triggers an exhaust gas recirculation valve in such a way that a desired value of the exhaust gas recirculation rate is established.

    摘要： Defective actuators in an internal combustion engine with at least one cylinder are detected. A mean value, in particular the arithmetic mean value, determines a measurement variable of all the actuators of a given type present on the cylinders. The measurement variable depends on at least one parameter. In a further step, a deviation is formed which is independent of the parameter. This ensures that the deviation across the entire parameter range remains constant. In a further step, the limit values, in particular the upper and lower limit values, are formed, the limit values being dependent on the deviation and on the mean value formed above. If an individual value of the measurement variable exceeds one of the two limit values, the method according to the invention detects this actuator as faulty and/or defective.
