Embodiment Construction

[0031] The damage prediction system includes the following components:

[0032] – transmission unit 1,

[0033] — measuring system and data logger2,

[0034] — Evaluation software 3

[0035] — Data Archive 4,

[0036] — display module 5 for the driver,

[0037] — Service life module 6,

[0038] — damage model 7, and

[0039] — Service life database8

[0040] The relevant components of the vehicle are continuously or intermittently monitored by means of the vehicle's own diagnostic sensor system 9 . The data of the diagnostic sensor device 9 are supplied to the measuring system 2 and the evaluation software 3 . While detecting the state of the component, it also checks the actual time and distance used by the component. The data archive 4 contains reference distances and reference periods until failure of each component to be monitored. If a damage to a component is detected, the evaluation software 3 compares the damage distance or time period until the damage occurre...

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 ofthe 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.

Description

technical field [0001] The invention relates to a method of predicting damage to motor vehicle components. Background technique [0002] From JP 2003-345421 A is known a vehicle with a management system, which is arranged so that vehicle components are monitored by a sensor system and sent to a central computer in case of problems. The central computer identifies the extent of the problem and determines damage to system components, and predicts further damage characteristics and service life. The user of the vehicle is informed about the results of this evaluation. In addition, various information is sent to the seller and stored in the database. As a result, recommendations for inspections and maintenance appointments are given to the user before any serious damage occurs. The disadvantage is that the information is not further evaluated until it has been sent to a central computer. Therefore, real-time evaluation of the measured data cannot be guaranteed, so that, in e...
