Definitions

  • the present invention relates to a method and a device for determining the remaining operating time of a product; the invention further relates to methods and a device for recording operating times up to the technical failure of the product as well as methods and a device for determining
  • Operating time threshold values of products as a function of certain time-varying operating sizes for monitoring the reliability of products and finally the invention also relates to a device arranged in a product whose reliability is to be monitored, for comparing the actual operating time of the product with operating time threshold values in accordance with the preambles of independent claims.
  • a method for determining the service life is known from DE 195 16 481 AI.
  • a control device for a motor vehicle is described which has an operating data memory in which the operating sizes of the motor vehicle are stored, which can provide information on the probability of failure or the future reliability of the control device.
  • Operating data memories are used to store essential data relating to the life history of a control unit in order to be able to make a statement as to the reliability of the control unit if necessary.
  • the object of the present invention is to enable the most accurate possible, non-model-based life expectancy for any products that have an operational data memory or have such access. Another task is the optimal acquisition of data and storage in an operating data memory in order to be able to use the memory optimally, in particular in order to save storage space.
  • the invention proposes, starting from a method for recording operating times up to the technical failure of a product, that values of specific operating sizes are recorded, the range of values of the individual operating sizes is divided into classes and the operating times depending on the class in that the recorded value of the company size falls.
  • the invention proposes a method and a device for determining the remaining operating time of a product until technical failure, values of a value range of at least one company size of the product being recorded, the value range of the company size being divided into classes and for each Class determines an operating time of the product and stores it in an operating data memory assigned to the product, the operating times being assigned predeterminable weighting factors and thus at least one weighted, cumulative operating time for the product is determined, the weighted, cumulative operating time being compared with at least one predeterminable operating time threshold value and the remaining operating time of the product being determined therefrom.
  • the product is designed, for example, as a control device or a subsystem (e.g. brake, engine, transmission, steering, etc.) of a motor vehicle.
  • the products have or are assigned to an operating data memory, in which the recorded operating variables or the operating times can be stored and called up again as required.
  • the operating data memory preferably has a non-volatile memory (for example an EEPROM or a flash EEPROM) as well as means for detecting the operating sizes or the operating times.
  • the operating data memory can be implemented, for example, in one or more control units.
  • the operating data memories are used to record discrete system states (e.g. number of start processes, number of emergency starts, number of thermal shutdowns, etc.) and the time-varying operating variables. For example, sensor data such as temperature, current, voltage, pressure, etc. a. detected.
  • a linear or non-linear subdivision of the value range m into several classes is carried out in each case in the value range of the operating variables which is permissible under operating conditions. Extreme values that lead to the immediate destruction of the product are outside the permissible value range.
  • the class assignment is based on the division of the entire value range into relevant load groups. The individual classes have a different influence on the aging / wear of the product.
  • Operating data memory is used to record the operating time of the product for each operating size in each class.
  • the determination of the individual technical operating time of a product and the calculation of the degree of wear at any given time is carried out on the basis of n classes of operating sizes. Due to the classified operating sizes, a particularly reliable and precise determination of the operating time of a product is possible, the storage requirement for the operating data memory being minimized, since it is not necessary to record the time course of the operating sizes. This enables particularly reliable preventive maintenance / repair shortly before the end of the technical operating life.
  • the values of the company sizes are recorded at regular time intervals and a class number of a certain class is increased if the value of a company size falls into this class.
  • each operating size of a specific product can thus be assigned an operating time histogram, from which the operating time of the product results for the operating size within a specific class.
  • the size of the operational data memory in bytes required for the operational data storage results from the product of the number of operational sizes, the average number of classes per operational size and the average number of bytes per class number.
  • the individual classes have a different influence on the aging / wear of the products. For this reason, the classes of company size are assigned weighting factors that determine the relative influence of a particular one
  • the invention provides for determining the weighting factors from a subset K of the products and then applying them to the subset Z of the products. As a result, the critical weighted cumulative operating times of the sizes for series production can be determined for the products from the subset S, and when they are reached, an end to the technical operating time can be concluded.
  • Is weighting factor assigned to class j of company size i and t_ijk is the service life of the product k for class j of company size i.
  • the correlation between the farm sizes can be taken into account, for example, by determining the weighting factors from an equation system in which the weighted cumulative operating times for each farm size are linked to one another by means of operators.
  • the operators can, for example, represent an AND operation (product formation), an OR operation (sum formation) or a fuzzy operation (e.g. an intermediate state between AND and OR).
  • the critical cumulative operating times for the individual operating sizes are to be determined, when they are reached it can be concluded that the technical operating time has ended.
  • a number of Z products are operated with the help of K products until technical failure, whereby the weighting factors calculated from the K products are applied to the classified operating sizes of the Z products.
  • the need for repair, replacement or maintenance by the product can be signaled for all series products equipped with operating data memories shortly before the critical threshold value is reached.
  • the company sizes saved in the product are evaluated as part of regular product maintenance.
  • a_ ⁇ j is the weighting factor assigned to class j of company size 1
  • t_ ⁇ Nk is the operating time of the product k for class j of company size 1.
  • the weighting factors come from the solution of the optimization problem
  • the correlation between the individual farm sizes is taken into account. It is assumed that several Large companies together lead to the technical destruction of the product.
  • the company sizes are linked to one another by means of pure AND operations (product formation). The weighting factors are determined in such a way that the weighted class sums of each product linked by the AND operator have a minimal "distance" from one another.
  • a link between several company sizes at the level of individual classes is provided. It is assumed that several company sizes within certain classes lead to technical destruction of the product.
  • the device be the first
  • the second means increase a class number of a certain class if the value of a detected company size m falls in this class.
