A method for operating a drive system including a drive engine for a motor vehicle, including carrying out an acceleration monitoring of the motor vehicle; switching to an alternative monitoring when a signal, which is relevant for the acceleration monitoring and for which a substitute signal exists, does not exist or has failed, and when a driver input which is below a predefined threshold value is specified, and/or a braking intent is specified.

Method and device for operating a drive system for a motor vehicle including an acceleration monitoring system

A method for operating a drive system having at least one drive engine for a motor vehicle, having the following: carrying out an acceleration monitoring of the motor vehicle, a changeover to an alternative monitoring being made when the acceleration monitoring can no longer carry out a reliable monitoring, and, in the alternative monitoring, an engine rotational speed being limited to a maximum permissible engine rotational speed; and ascertaining the maximum permissible rotational speed as a function of a rotational speed specification specified by a driver's request.

Method and device for operating a drive system for a motor vehicle

A method is provided for calibrating an acceleration sensor for ascertaining a longitudinal acceleration of a motor vehicle. One or multiple sensor parameter(s) of a sensor model of the acceleration sensor is/are determined, via which the actual longitudinal acceleration of the motor vehicle is ascertainable from a physical sensor variable. The method includes the following steps:

Method and device for calibrating an acceleration sensor in a motor vehicle

A method for the safe operation of a drive of a motor vehicle, the drive being controlled by at least one control unit, including acceleration monitoring in which the allowability of an operating state of the drive results as a function of a comparison of an ascertained actual acceleration with an allowable acceleration, a fault response being initiated as a function of whether a braking request is present, if the comparison shows that an inadvertent acceleration is present.

Method and device for monitoring a drive of a motor vehicle

A method for monitoring a drive of a motor vehicle, including acceleration monitoring, including: ascertaining an actual acceleration of the motor vehicle with the aid of a signal of a kinematics sensor, in particular of an acceleration sensor or of a wheel speed sensor, ascertaining a permissible acceleration of the motor vehicle as a function of a position of a gas pedal, and ascertaining the permissibility of an operating state of the drive as a function of the ascertained actual acceleration and the ascertained permissible acceleration, the permissibility of the operating state of the drive being monitored with the aid of alternative monitoring instead of acceleration monitoring when the operating state of the drive meets at least one predetermined condition.

A method for monitoring a motor vehicle includes: monitoring whether a speed of the motor vehicle indicates a stopping condition of the motor vehicle; detecting whether at least one vehicle operating condition indicating an imminent unintentional acceleration of the vehicle exists; and triggering a fault response if (i) the vehicle is in the stopping condition and (ii) the at least one vehicle operating condition indicating an imminent unintentional acceleration of the vehicle exists.

Method and device for preventing unintentional acceleration of a motor vehicle

Methods for ascertaining the combustion noises of an internal combustion engine need only a structure-borne noise sensor and may be carried out using little computing power.

Method for ascertaining the noise emission of an internal combustion engine

A method for metering fuel into a combustion chamber of an internal combustion engine is provided, in which a fuel quantity to be metered for a combustion is metered by a preinjection and at least one additional injection, and in which, in the operation of the internal combustion engine, quantity errors of the preinjection are ascertained from the signal of at least structure-borne noise sensor. The method is distinguished in that a correction value is formed as a function of the quantity error of the preinjection, and at least one of the additional injections is corrected using the correction value. A control device is also provided that controls the method.

Method and control device for metering fuel to combustion chambers of an internal combustion engine

A method and control unit for metering fuel into at least one combustion chamber of an internal combustion engine comprising at least one pilot injection and one main injection per combustion cycle, combustion features being detected and an effect of a fuel quantity injected prior to the main injection being ascertained from the combustion features. An actual value of a combined effect of at least two pilot injections per combustion cycle is ascertained and the actual value is regulated to a setpoint value via an intervention on at least one of the pilot injections.

Method for metering fuel into combustion chambers of an internal combustion engine

The invention is based on a method for operating an engine drive train having a connectable electrical machine, the electrical machine being drivingly connectable to the engine in whose exhaust gas system an exhaust gas cleaning device is located. A moment output of or drawn by the electrical machine is impressed on a moment of the engine that is demanded by an engine control unit, as a function of an operating state of the exhaust gas cleaning device.

Method of and apparatus for operating a drive train with an electrical machine

A method for controlling an internal combustion engine calculates the generated internal torque for each cylinder on the basis of the signal generated by an angle of rotation sensor for detecting the angle of rotation of the crankshaft, so that a rapid and precise regulation of the torque supplied by the internal combustion engine may be achieved.

Method and device for operating an internal combustion engine

A method for operating an internal combustion engine enables an improved determination of a preferred position of a shaft of the internal combustion engine. The preferred position of the shaft is derived here on the basis of a signal characterizing a course of combustion of the internal combustion engine as a function of a phase relation determined between this signal and the preferred position of the shaft.

Method for operating an internal combustion engine

A device and a method for controlling and/or regulating an internal combustion engine, in particular an internal combustion engine having direct injection. A regulation adjusts a combustion state variable, that characterizes the combustion state, to a setpoint value. A control and/or a regulation influences a torque variable that characterizes the torque of the internal combustion engine and/or the noise variable that characterizes the noise of the internal combustion engine, using a control variable.

Method and device for controlling and/or regulating an internal combustion engine

In an internal combustion engine, a structure-borne noise generated in a combustion chamber is detected by a structure-borne noise sensor. A quantity is ascertained on the basis of the structure-borne noise signal. A reference quantity of an undrifted structure-borne noise sensor is ascertained for a certain reference operating state for the combustion chamber, during continuous operation of the engine the quantity is ascertained for the reference operating state, and from a change over time of the ascertained quantity with respect to the reference quantity, a drift of the structure-borne noise sensor is ascertained.

A device and a method for controlling an internal combustion engine, in particular a diesel engine, are described. Based on the signal from a structure-borne noise detector, parameters are determined which are used to regulate the internal combustion engine. At least one parameter is determined through an analysis that includes a filtering which selects at least two angular ranges.
