Abstract

The invention relates to a method for forecasting the damage of components of a motor vehicle, comprising the following steps:

• • Providing a damage model for at least one component;
  • detecting the loading of the component;
  • determining the loading and damaging of the component along a damage distance and/or over a damage period;
  • determining a reference distance and/or reference period on the basis of the determined loading of and/or damage to the component;
  • comparing the damage distance and/or the damage period with the reference distance or reference period;
  • determining an acceleration factor from the damage distance and reference distance or damage period and reference period.

Claims

1. A method for forecasting the damage of components of a motor vehicle, comprising the following steps:

providing a damage model for at least one component;

detecting the loading of the component;

determining the loading and damaging of the component along a damage distance and/or over a damage period;

determining a reference distance and/or reference period on the basis of the determined loading of and/or damage to the component;

comparing the damage distance and/or the damage period with the reference distance or reference period; and

determining an acceleration factor from the damage distance and reference distance or damage period and reference period.

2. The method according to claim 1, including determining the expected residual service life or residual distance.

3. The method according to claim 1, including summing the damage percentages of all damage distances and/or damage periods of the component and comparing the sum with a maximum value saved in a database.

4. The method according to claim 3, including determining damage to the component upon reaching the maximum value.

5. The method according to claim, including estimating the remaining service life or remaining distance of the component from the difference to the maximum value.

6. The method according to claim 5, including determining the remaining service life on the basis of at least one service life model stored in a database.

7. The method according to claim 6, including providing the driver with information in an optical, acoustic or tactile manner on a current damage, a service life reserve, a forecast on expected damage, the acceleration factor and/or recommendations on further driving style.

8. The method according to claim 7, including sending current information on damage models, service life models, reference distances, reference periods and maximum damage percentages is sent by way of a wireless connection of the databases.

9. The method according to claim 8, wherein the loading of the component is gained at least partly from simulation data.

10. The method according to claim 9, including calculating a parameter which is relevant for the loading of the component on the basis of a predetermined required remaining service life or remaining distance.
