UN Regulation 171 Homologation of Level 2+ Driver Assistance Systems

UN R171 Homologation Capabilities

With Level 2+ systems, vehicles are capable of controlling steering, acceleration, and braking, while the driver remains in charge and the system continuously monitors their level of attention. IDIADA provides end-to-end support for manufacturers deploying these advanced systems, with particular expertise in assisted highway driving, including complex manoeuvres such as automated lane changes under the driver's active supervision.

Our comprehensive service covers all phases of the homologation process:

• Interpretation of regulatory requirements under UN R171
• Design and execution of tests, carried out on tracks, in real-road environments, and in simulated scenarios
• Safety audits to ensure system compliance
• Virtual tools credibility assessments
• Verification that manufacturers have the necessary capabilities to monitor system performance throughout the vehicle's entire lifecycle
