Abstract

An automatic damage identification system in vehicles helps car sharing and car rental companies to monitor damage as it happens and to attribute it to a responsible person. The working group "Automotive Electronic Systems" at the Institute of Electrodynamics and Microelectronics (ITEM), Universität Bremen, initiated in early 2012 the joint project KESS – Konfigurierbares Elektronisches SchadenidentifikationsSystem, engl.: Configurable Electronic Damage Identification System – funded by the German Federal Ministry of Education and Research. The innovative damage identification system developed in this project offers transparency to car sharing/car rental businesses and their customers. KESS detects and documents in real time minor damages - such as dents and scratches - that happen during usage a car through the customer or through vandalism. First, a technical overview about the complete workflow in such a system is part of talk. Starting with the detected raw signals of structure-borne sounds (sensor data acquisition), through to signal evaluation and algorithmic assessment of the characteristic indicators for damage (signal filtering and feature extraction), to wireless data transmission of the registered damage to the damage management system of the car fleet owner (information flow and communication). This contribution focuses on two different approaches for algorithm design of the subsequent reasoning framework stage in a main electronic unit. Both ways make it easier to decide which final result of the damage assessment should be transmitted to the fleet management server.
