Embodiment Construction

[0021] figure 1 A schematically illustrated flow chart of a method 1 according to the invention for designing and dimensioning a new component 2 of a motor vehicle 3 is shown. In order to use the method 1 according to the invention, it is first necessary to develop algorithms suitable for the on-line load spectrum determination and on-line damage degree determination of the reference component 4 and to implement them in the corresponding control devices of the motor vehicles 5 of the motor vehicle fleet 6 . With the aid of these algorithms, during the operation of the motor vehicle 5, in a determination step 7 carried out on all motor vehicles, the continuously current load spectrum, the degree of damage and possibly supplementary vehicle state parameters are determined and transmitted in a transmission step 8 Wirelessly transmitted to the central database 9. The determination step 7 and the transmission step 8 carried out for different motor vehicles 5 are performed asynchr...

Abstract

The invention relates to a method (1) for designing and dimensioning a new part (2) of a motor vehicle (3). All of the motor vehicles (5) of a motor vehicle fleet (6) have a reference part (4) with anidentical structure, and the reference parts (4) and the new part (2) are of the same component type. Load spectra and damage levels of the reference parts of all the motor vehicles (5) of the motorvehicle fleet (6) are continuously ascertained on the basis of sensor and vehicle state information available in each motor vehicle (5) using specified algorithms. The load spectra and damage levels are stored in a central database (9). A reference stress on a component of the component type is ascertained regularly on the basis of the load spectra and damage levels provided in the central database (9) at a specific point in time for the reference parts (4) of all of the motor vehicles (5) of the vehicle fleet (6). The new part (2) is designed and dimensioned while taking into consideration the reference stress. The reference stress is less than the maximally occurring stress on all of the reference parts (4).

Description

technical field [0001] The invention relates to a method for designing and dimensioning new components of a motor vehicle. Background technique [0002] When developing a new motor vehicle, the various components of the motor vehicle to be newly developed are designed and dimensioned by means of known methods. In order to be able to maintain the functional capabilities of the motor vehicle during its service life, new components are designed in such a way that they can withstand the loads and components that occur during the service life of the motor vehicle wear and tear. For this purpose, test drives and computer simulations are usually carried out in order to determine the loads which may occur during the service life of the new component and then to design the new component on the basis of these results. [0003] An alternative method for designing and dimensioning a new component of a motor vehicle, namely a transmission to be newly developed, is described in publicat...
