  1. ECE/TRANS/WP.29/GRE/2013/57Alternative aiming/leveling(explanations) Informal documentGRE-70-41-Rev.1 (70th GRE, 21-23 October 2013, agenda item 4(b)) Tomasz Targosinski Ph. D. Eng Poland 70 GRE 21-23 October 2013

  2. Informal document No. GRE-65-30 (65th GRE, 28-31 March 2011, agenda item 5(d)) „Analysis of the influence of aiming, on visibility distance and glare”

  3. - 2000 lm (artificial arbitrary criterion)- Gas discharge (35W, 25W?)- LED AUTOMATIC LEVELLING AT PRESENT - DESIGN ORIENTED REQUIREMENT No relation to performance

  4. HISTORICAL ARTIFICIAL AIMING/LEVELING PROVISIONS

  5. PRESENT REGULATORY (Reg.48) ROAD ILLUMINATION DISTANCE [m]

  6. Real sizes and distances 200m 100m 20m 0m Possible road illumination distance in Reg 48. CoP tolerances not taken into account

  7. Proposed road illumination distance dependent aiming/leveling (75m, 50m-100m) 100m 75m 50m

  8. First version of Polish proposal (aiming/leveling) Informal document No. GRE-65-13 (65th GRE, 28-31 March 2011, agenda item 5(d))

  9. Informal document No. GRE-67-33 (67th GRE, 26-29 March 2012, agenda item 4(c)) - Explanations regarding decision making - Three possible options: Optimum (a) With information to drivers (c) Arbitrary obligatory automatic leveling (b)

  10. BASE FOR REAL HUMAN DECISIONS IN MOST SITUATIONS IMAGINATION BELIEF FEELINGS EMOTIONS INTERESTS SCIENTIFIC CONFIRMED REAL VERIFIABLE REPEATABLE RATIONALITY IS IN MINORITY

  11. MY BOSS WHO IS RESPONSIBLE FOR ROAD SAFETY ?(in lighting domain) ADMINISTRATIVE SERVICE LAW CREATORS (GTB, GRE, WP29, EU) MANUFACTURERS GOVERNMENT TECHNICAL SERVICE SERVICE DRIVER Me PTI

  12. GLARE PROTECTION Glare reduction by proposal GRE 2012/21 Proposal reduce glare comparing present situation for most vehicles, especially cars

  13. HOW WILL WORK GRE/2012/21 1. GUARANTED VISIBILITY DISTANCE >[75m] ? YES NO 2. GUARANTED GLARE PROTECTION ? (ACCORDING PRESENT HEADLAMPS REG.) 2. GUARANTED GLARE PROTECTION ? (PRESENT HEADLAMPS REG.) NO NO OBLIGATORY AUTOMATIC LEVELLING (German proposal) YES YES 3. INFORMATION FOR DRIVER (OPTIONAL) 3. INFORMATION FOR DRIVER A (optimal) B(outside GRE/2012/21 ) C(possible)

  14. Comments on GRE/2012/27(Lighting & Signalling WG) Headlamp Initial Aiming Informal document No. GRE-67-27(67th GRE, 26-29March 2012, agenda item 4(c)(i)) Informal document No. GRE-68-20 (68th GRE, 15-18 October 2012, agenda item 4(c)(i)) OICA strong opposition against propsal

  15. Polish strong response against OICA arguments Informal document No. GRE-68-31(68th GRE, 15-18 October 2012, agenda item 4(d))

  16. Proposed Initial nominal aim to correspond to 75m theoretical range • Under proposal, What for are needed overlaps? • No overlap between height bands • Mostheadlamps would be aimed higher than at present • It will depend on manufacturers decision • and choice of range of amended Reg.48 • (30 to100m or 50 to 100m) • It will be safety oriented advantage and goal of amendment because of longer average road illumination distance. • Risks increased glare. • Not true. Decreased glare • comparing present state.

  17. Polish greatly mitigated proposal(s) ECE/TRANS/WP.29/GRE/2013/15 & ECE/TRANS/WP.29/GRE/2013/57

  18. Polish greatly mitigated proposal(s) Near as today requirements

  19. ECE/TRANS/WP.29/GRE/2013/57 Fully optional reguirements

  20. ECE/TRANS/WP.29/GRE/2013/57 GOOD, COMBINED PROPOSAL true „PERFORMANCE ORIENTED” OICA NEARLY AS TODAY BUT „PERFORMANCE ORIENTED” ROAD ILLUMINATION DISTANCE AS CRITERION, NO RESTRICTIONS MANUFACTURER CHOICE NO 2000 lm NO LIGHT SOURCE CRITERION AS TODAY: ARTIFICIAL 2000lm „DESIGN ORIENTED” OR MANUFACTURER CHOICE
