摘要:
The invention relates to a method and device for recording serviceable lives, especially up to the technical failure, of a product and for determining the remaining serviceable life of the product. The aim of the invention is to be able to estimate, in a manner that is as precise as possible and without support provided by a model, the lifetime for any product, which is equipped with an operational data memory or has access to such a memory, without storing temporal signal progressions. To this end, the invention provides that the determination of the remaining serviceable life of the product, the recording of serviceable lives of products, and the determination of the serviceable life threshold values are carried out on the basis of operational quantities that are subdivided in classes (so-called classified operational quantities). For this, weighting factors (a_ij) are firstly determined. Afterwards, the weighting factors (a_ij) are used in order to determine weighted cumulated serviceable lives and serviceable life threshold values. This enables the monitoring of the reliability of s = 1...S products used in series.

The invention relates to an energy storage device (1) for generating an n-phase supply voltage, wherein n ≥ 1, comprising a plurality of energy supply branches (1a) that are connected in parallel, each of which is connected to an output connector (6) of the energy storage device (1). Each of the energy supply branches (1a) is provided with a plurality of energy storage modules (2) that are connected in series, each having at least one energy storage cell (2a), and comprising a plurality of coupling modules (3) connected to one of the plurality of energy storage modules (2), respectively, each configured to couple, or to bridge, the connected energy storage module (2) with the energy supply branch (1a). The energy storage device further comprises a control system (9), which is connected to the coupling modules (3), and which is configured to actuate each of the coupling modules (3) as a function of a value of the aging functions of each energy storage module (2) for coupling each of the connected energy storage modules (2) with one of the plurality of energy storage branches (1a), and to turn the energy supply branches (1a) on or off by way of actuating the branch coupling modules (4) as a function of the sum of the aging functions of the energy storage modules (2) in the respective branches (1a), and as a function of the load demand of an electric consumer (8).

The invention relates to a steering wheel (1) for a vehicle having several sensors (7, 9). The sensors (7, 9) are divided into a multitude of segments (13, 15) thus enabling a local highly resolved detection of the position of the hands on the steering wheel (1). The inventive method for evaluating the signals output by the sensors (7, 9) enables the position of the hands to be detected and additionally enables the maximum possible steering angle on the steering wheel (1) to be determined without changing the position of the hands. A control device derives control operations and control signals from this information.

The invention relates to a device and a method for storing and/or evaluating data in a memory in a vehicle. The data is transmitted in the vehicle via a data bus (108). Components such as vehicle systems (111, 112, 113), sensors (114), actuators (115) and additional vehicle components (116) are connected and can be connected to the data bus (108). The memory is configured as a central memory medium (101) for the components connected to the data bus and is also connected to the data bus. The data is permanently stored in the memory medium (101) during the entire utilisation period of the vehicle. In a preferred embodiment, the data is interpreted by evaluation means (102-104) which can be connected to the memory medium in such a way that a measure for the utilisation and/or wear and tear of the vehicle and/or the components is produced.

The invention relates to a system and a method for storing data in a motor vehicle. As storage medium having a very large storage volume the invention provides for a data storage card which is assigned to the motor vehicle and housed in a vehicle-side interface designed for reading/writing into the storage card. The motor vehicle is equipped with a data bus to which the interface as well as other systems, components and sensors of the motor vehicle are connected. A vehicle-mounted error-diagnosis unit generates malfunction codes which together with other relevant data of different vehicle-side systems are constantly stored in the data storage card so as to generate permanent load profiles and are maintained throughout the service life. The stored data include data on the motor vehicle and its owner, malfunction codes reflecting the state of different systems and components of said motor vehicle, operating data, repair and service information and possibly data regarding mandatory technical checks as well as technical specifications and operating instructions. From an evaluation of these data conclusions can be drawn which are relevant for product improvements and repair strategies and indicate the performance of a motor vehicle in the field.

The invention relates to a method for operating an internal combustion engine (1), especially an internal combustion engine pertaining to a motor vehicle, by means of a control appliance (2) for controlling/regulating the operation of the internal combustion engine (1) according to an air mass sensor signal (L_1) of a first air mass sensor (HFM_1). A first auxiliary signal (H_1), obtained from an additional sensory mechanism or from models of the internal combustion engine (1) by means of calculation, enables a plausibility control to be carried out or the substitution of the air mass sensor signal (L_1) if interference is detected in terms of said signal (L_1), thus ensuring that the internal combustion engine (1) can continue to be operated in an optimum manner.
