Definitions
- the invention relates to a method for the design and dimensioning of a new part of a motor vehicle.
- the new components are basically designed so that they affect the loads occurring during the life of the motor vehicle as well as over the life of the vehicle
- Component type are, with continuous load and collective
- Algorithms are determined and where the load spectra and damage levels in a central database
- Reference load is less than the maximum load of all reference parts.
- the method according to the invention is thus intended to continuously determine load spectra and damage levels for each vehicle using known methods.
- Life of the examined reference part for the design and dimensioning of the new part can be used.
- the At the beginning of the development already available load spectra and damage levels are processed in order to determine the anticipated stress on the reference components over the intended service life of the reference components.
- This reference stress can be regularly adjusted during the development process by load collectives and damage levels newly gained during the operation of the vehicles of the motor vehicle fleet in order to further improve the dimensioning and design of the new part.
- the new part can be designed based on a sufficiently large database and
- Control units the load collectives and damage levels determined in each case regularly to the central database connected to the control units for data transmission
- the load collectives and damage levels are thus determined on appropriate ECUs - onboard - and using modern Communication systems regularly transmitted to a central database.
- Damage levels are demand-oriented carried out at a later date, the computational power and storage capacity required for the calculation of the given algorithms does not have to be provided in the individual control units, but the load collectives and damage levels on appropriately established
- the method according to the invention allows more precise dimensioning and dimensioning of the new part
- the vehicles whose components are expected to fail in the near future will be identified.
- the new part for example, for a normal driver who is expected to burden the new part in an average manner, so that, for example, 90% of the new parts installed over the entire vehicle fleet will reach the intended service life and only 10% the new parts must be replaced as a precautionary measure before expiry of the planned period of use.
- the reference stress is often referred to as the reference utility profile.
- ECUs the respectively determined sensor and Transmit driving status information and / or load collectives and damage levels to the database via wireless data links.
- Data transmission for example via mobile networks or the like can be used.
- mobile networks or the like can be used.
- new technologies such as
- control devices transmit additional vehicle state parameters to the database in addition to the load collectives and damage levels.
- vehicle state parameters may be, for example, information about each
- Vehicles provided sensors are determined and available.
- the invention provides that the reference stress, taking into account weight ⁇ and cost models for the production of the new part and / or CC> 2 models for estimating that of the
- the expected fuel consumption and the expected service life of the new part can advantageously be taken into account.
- Reference parts is. In particular, even if at least individual new parts of the motor vehicle fleet already based on the
- Damage level limit is exchanged. This replacement is advantageously carried out at the expense of the manufacturer in the context of regular vehicle maintenance, so that the customer no disadvantages arise through the exchange.
- the determined load collectives and damage levels suggest too rapid an increase in the actual damage and, for example, a minimum service life of the respective reference part can not be achieved without adapting the operating strategy.
- Motor vehicles can also be used to determine a residual value of the respective motor vehicle.
- Motor vehicles can also be used to determine a residual value of the respective motor vehicle.
- Load collective criteria and / or damage level criteria are selected and subsequently exchanged in order to be able to examine in more detail the specific reference parts in laboratories.
- the information obtained here can in turn be used for the design and dimensioning of the new part.
- the information determined in this way can be used according to the invention in that, on the basis of the examination of the exchanged reference parts for determining the
- the invention provides that the injury level limit regularly based on the in the central database at a given time
- Motor vehicle fleet is redetermined. On the basis of the information on the new part determined during the operation of the motor vehicle fleet can be determined in advance
- Damage level limit be adjusted continuously, so that a needs-based exchange of the
- Reference parts of the motor vehicle fleet is reached, which will fail with a high probability within the next maintenance interval. As a result, an unnecessary exchange of reference parts can be avoided or the number of unnecessarily exchanged reference parts can be reduced.
- FIG. 1 shows a schematically represented flow chart of the method 1 according to the invention for the design
- the information contained in the database 9 are then used to interpret the new part 2 in a design step 10 and for this purpose a
- Damage level check step 11 is determined that a concrete reference part 4 a predetermined
