    摘要: A method for regulating the smooth running of a multicylinder internal combustion engine. An inverse linear path model estimates a characteristic process variable from state variables of the internal combustion engine, that is to say actual values, in particular engine speed, fuel quantity, operating temperature, charging pressure, etc. A desired value is compared with the actual value that is determined from state variables of the internal combustion engine by a measuring element. The actual value shows the rotational acceleration contribution of each cylinder. The difference between the actual value and the desired value is supplied to a controller that corrects the combustion in the individual cylinders in such a way that the actual value approaches the desired value. This ensures that the regulation for the smooth running of the engine takes effect both for stationary and non-stationary operating phases of the internal combustion engine.

    摘要: A method for the closed-loop control of a nonlinear controlled system in which a state variable of the controlled system is determined and an actuating value is determined using a control method and a reference variable. In addition, by using the state variable of the controlled system, a correction value is read from a linearization characteristic curve and multiplied by the actuating value and the product is specified as new desired value for the controlled system. The linearization characteristic curve is chosen in such a way that multiplication of the linearization characteristic curve by the nonlinear control action of the controlled system yields a linear control action.

    摘要: A method of starting an internal combustion engine having an injection system and characteristic variables includes the steps of supplying an injection system with an operating parameter that is determined from characteristic variables, supplying a speed regulator with an initialization value as an initial starting variable, and regulating a speed of an internal combustion engine up to an idling speed with the speed regulator based upon the initialization value. The acceleration to idling speed is carried out with the aid of the speed regulator based on the initialization value. The injection system is supplied with a mass of fuel to be injected. Regulation is carried out with a speed regulator already present in an engine controller. The initialization value is stored in a characteristic curve as a function of coolant temperature. The initialization value is applied to a first injection operation of the internal combustion engine.

    摘要: A device for determining a start of injection in a direct-injection internal combustion engine has a magnetoelastic pressure sensor disposed in an injection line leading to an injection valve which detects pressure changes in the injection line owing to an injection process of the injection valve by utilizing the magnetoelastic effect. The device also has an evaluation device that determines a dead time between an initiation of the injection process and the start of injection with the aid of the measurement signal of this magnetoelastic pressure sensor.

    摘要: A transmission system includes an internal combustion engine, a vehicle drive train and a fuel supply. A method for controlling the internal combustion engine for preventing low frequency bouncing oscillations includes connecting a transmission element upstream of the transmission system. The transmission element has a transmission function inverse with respect to a transmission function of the transmission system. A selection of a time constant of the transmission element not only prevents the bouncing oscillations but also achieves a damping of load jolts.

    摘要: A method for detecting a preinjection picks up and evaluates a vibration signal which occurs when a nozzle needle strikes a needle seat of an injector of a direct-injection internal combustion engine operating with a preinjection and a main injection. A sensor for structure-borne noise is provided on the cylinder outer wall for detecting the vibration signal. Based on the evaluation of the vibration signal a conclusion is made on the presence or absence of the preinjection in a combustion cycle. A device for detecting a preinjection is also provided.
