Qualifizierung der in Deutschland verwendeten Fahrzeug-Rückhaltesysteme mit verbessertem Schutz für Motorradfahrer nach den aktuellen europäischen Spezifikationen

Passive safety roadside equipment optimized for impacting motorcyclists is used since quite some time at exposed spots to protect potentially impacting motorcyclists. Especially sliding underneath guardrails or impacting at the post is to be prevented. Due to the lack of national and international standards those devices have been tested according to self-defined procedures. Since the publication of the Technical Standard CEN/TS 1317-8:2012 (now DIN CEN/TS 17342:2019-10; DIN SPEC 18193:2019-10) there is a technical regulation which at least covers the sliding impact of a motorcyclist. Until now it is unknown, if the used devices fulfil those test requirements. Basically it has to be distinguished between OEM solutions and not patented solutions which has been built according to former regulations. Within this project the focus is laid on the retrofit of the standard passive safety device ESP (simple steel guardrail).
Aim of this project was to design, assess and modify additional components for the ESP in regard to pass the Technical Standard CEN/TS 13117-8:2012. The nowadays commonly used underride protection of the ESP 4.0 UFS as well as additional components to reduce the impact severity have been tested and designed. However it was not possible to achieve a solution which passed the tests. Problems and fail criteria were identified which can be used as a basis for further projects.
