This proposal is to add Component and Separate Technical Units (STU) approvals regulatory supplement to the UN Regulation No. 159 for “Uniform provisions concerning the approval of motor vehicles with regard to the Moving Off Information System for the Detection of Pedestrians and Cyclist” .
Document identifies challenges with headlamp aiming for glare prevention. UP-DOWN aiming challenges include vehicle actual load and cut-off line definition. LEFT-RIGHT aiming challenges include references on the vehicle and kink point definition. Cut-off line definition makes it difficult to check up-down aiming; kink point definition makes it difficult to check left-right aiming. The beam pattern must be used to check alignment. The way forward includes reviewing criteria for passing-beam orientation in approval and adapting inspection criteria accordingly.
The hard-working team identified glare issues in four areas: aiming procedures lack clear definitions of cut-off line and kink point, making PTI inspection difficult; high-mounted headlamps tend to glare lower vehicles in front, and cleaning hardware and auto-levelling performance are insufficient; PTI lacks a dedicated chapter on provisions; and measurements using 75 kg on driver’s seat are impractical, alignment is not mandated at end-of-line, and no general requirements exist for headlamp testers.
