欧盟降低行人保护第二阶段的限制要求.pdfVIP

The original EC Directive on pedestrian protection, 2003/ 102/EC, introduced pedestrian protection requirements in two stages. Both stages utilised the same test procedures, but the inj ury limits for Stage 2 were more stringent than those applied in Stage 1. Despite the fact that the technical requirements for 2003/ 102/EC were only finalised after many years of discussion and negotiation, and numerous cost/benefit and feasibility studies, many vehicle manufacturers were still of the opinion that compliance with the Stage 2 limits was not feasible. For this reason, 2003/ 102/EC included a review clause on the feasibility of the Stage 2 limits, with the review to be undertaken using data gathered during testing to the Stage 1 requirements. The review on the feasibility of the Stage 2 limits was concluded in 2007 and, as a result of this review, a number of relaxations to the Stage 2 limits were proposed (Note: these revised Stage 2 limits were used as a basis for the recently published Global Technical Regulation on pedestrian protection, GTR No. 9). To offset these relaxations and to ensure that the reductions in pedestrian fatalities and inj uries predicted for the original Stage 2 limits were still achieved, the European Commission proposed mandating the fitment of Brake Assist systems. Brake Assist systems are systems designed to sense an emergency braking situation and assist the driver in achieving the maximum achievable deceleration in the prevailing conditions. Such systems have been shown to have significant benefits in terms of pedestrian protection.
