Final report: Study on the assessment and certification of automated vehicles
Published on: 20/07/2017
This study informs the Commission on how to regulate upcoming automated steering functions in vehicles. In particular, ‘lane change assist’ (LCA) and enhanced ‘lane keep assist systems’ (LKAS). These functions are currently not regulated.

Tasks and results of the study

Task 1 - State of the art review

The objective of this task was to assess current automated steering technology and review likely future systems.

Results: A comparison of the functionality of currently available or upcoming automated lane keeping and lane change systems was made.

Task 2 - Best practice: regulation of complex automated systems in other industries/sectors

The objective of this task was to review safety testing processes used in other industrial sectors (i.e. rail, nuclear and aviation. This way approaches to managing safety in these areas can inform the approach applied to vehicles.

Results: The main standards of safety testing processes in other industries (railway, nuclear, process, machine and aviation) are, in principle, similar to those in the automotive industry. To a certain extent, they could be used for the type-approval of automated vehicles.

Task 3 - Review of the proposal currently discussed in the framework of UNECE

The objective of this task was to review the current proposal, identify any potentially safety-relevant issues and make initial recommendations on how they may be resolved.

Results: The following major issues were identified

  1. Inconsistent interpretation and application of the assessment of ‘complex electronic systems’ (Annex 6)
  2. Safety in all real-world scenarios (operational safety), in particular for higher the category (hands-off lane keeping or lane changing)
  3. Driver monitoring
  4. Lack of coverage for in-service safety performance

Task 4 - Identify additional requirements to ensure that the system functionality is safe in all real world driving scenarios

The objective of this task was to propose additional requirements to help resolve the issues identified in task 3.

Results: Proposals were made under task 4 to better cover the issues identified.

Task 5 - Over-the-air updates/Type-approval updates

This task aimed to provide options for type-approval arrangements that could apply to vehicles undergoing over-the-air (OTA) updates after gaining type-approval. Here, the updates materially change the characteristics or performance of the vehicle or its safety systems.

Results: Suggestions to extend the concept of vehicle type-approval to over the air updates.
