Areas of focus
Dynamic scenario-based inspection of automated and connected driving systems
- The development and equipment of (highly) automated, connected assistance and driving functions is progressing dynamically.
- To be able to fully exploit the accident prevention potential (Vision Zero) of these driving functions and to avoid risks for society, they must function without errors and be regularly checked for possible safety risks.
- Furthermore, it remains necessary to ensure the proper and professional inspection of these functions by a neutral third party with regard to fit ment and condition, as well as function and performance in particular. The inspection organisations provide this with expertise and technical competence.
- New inspection methods and tools for monitoring of automated, connected assistance and driving functions are currently being developed and prepared for near-term implementation in the inspection bodies.
- In addition to static methods, scenario-based test methods offer the possibility of testing the response of the vehicle during a specific scenario by suitably depicting the traffic environment (virtually/physically). Several methods, including a dynamic vehicle inspection with a moving target or on functional test benches with environmental simulation, are being evaluated in appropriate pilot environments.
Event-driven remote-assisted inspection of automated and connected driving systems
- On the basis of defined, remotely transmitted vehicle in formation, abnormalities during operation can be quickly detected and any necessary steps, like repair initiated.
- In supplementing periodic on-site inspections, event-driven remote-assisted inspections ensure a high level of road safety over the entire service life of the vehicle.
- Requirements on safety and environment relevant systems, and their abnormalities must be defined and adapted dynamically by official bodies, as is the case today for periodic vehicle inspections.
Software inspection of all vehicle systems with relevance to safety and the environment
- Software and corresponding updates, in particular for safety-relevant systems (e.g. driving dynamics, driver-assis tance systems, engine management), must be able to be checked for conformity and integrity.
- In the event of software updates causing a risk to road users or a deterioration of environmental performance, measures must be taken ranging from recalls ordered by the authorities to the revocation of the operating licence.
- Software checks using the PTI-Adapter are already an integral part of the PTI. They are carried out e. g. following software-related recalls initiated by the German Federal Motor Transport Authority (KBA).
- With entry into force of the General Safety Reg. (GSR), new safety relevant systems have become mandatory and the software of these systems is certified in the type approval. Functionality and software integrity are inspected in PTI as software-checks.
- The authorities must have access to comparison values for software and corresponding updates (including software numbers and integrity features such as checksums) in order to be able to implement a corresponding conformity check.
Holistic inspection of vehicle emissions for better air quality
- A holistic life-cycle review of applicable emission thresholds is ensured through synchronised requirements for certification, type approval and periodic inspection within the context of the PTI.
- Appropriate combination of on-board diagnostic values and extended tailpipe measurement as part of the PTI: measurement of the particle count also in gasoline engines and further development of efficient nitrogen oxide measuring methods for diesel engines, taking into account load points in the entire spectrum of the combined exhaust gas after-treatment systems.
- Supplementation of the PTI by independent monitoring of the fuel and/or power consumption of conventional vehicles and hybrid vehicles, as well as the purely electric distance travelled by hybrid vehicles.
- Independent consistent field monitoring based on remotely transmitted vehicle information complements market surveillance and product monitoring measures by the vehicle manufacturers (in-service conformity).
Safe e-mobility
- High-voltage (HV) components and the high-voltage storage system are checked for faults via the electronic vehicle interface, but visual inspection of the components, lines, markings, etc. also continues to play an important role.
- The complexity of high-voltage cells and battery management require continuous field observation and further development of test methods and technologies. Not only the charging/discharging efficiency and the durability, especially the safety state of the high-voltage storage system is highly relevant in this context. The evaluation is also based on data from long-term observation.
- Reliable inspection of HV safety is implemented quickly and efficiently by measuring equipotential bonding and insulation resistance at the charging port.
- In combination with field data, dynamic inspection and vehicle diagnostics, essential functions of the HV drive must be tested:
- Testing of the HV insulation or insulation monitoring devices
- Testing of start-up prevention during charging processes
- Inspection of the electrical efficiency
- Checking of the traction batteries for safety-critical features, such as ageing effects or mechanical damage
Access to vehicle data via OBD and remote interfaces
- Independent and unrestricted access to vehicle data via both the physical interface (OBD) and the remote interface (OTA) are necessary for performing sovereign tasks such as the PTI.
- Secure handling of – and neutral access to – mobility and vehicle data is ensured by suitable TrustCenter solutions for authorisation management.
- The vehicle owners or users are the key players and they decide on the (private, non-official) use and sharing of the mobility or vehicle data they have generated.
