       *  For relative speeds between the listed values (e.g. 53 km/h), the maximum relative impact speed (i.e. 35/40/30/35 km/h) assigned to the next higher relative speed (i.e. 55 km/h) shall apply. For masses above the mass in running order, the maximum relative impact speed assigned to the maximum mass shall apply.
          with  α = Wr/W × L/H, where :

                  (a) Wr is the rear axle load.

                  (b) W is the subject vehicle mass in running order.

                  (c) L is the subject vehicle wheelbase.

                  (d) H is the subject vehicle centre of gravity height in running order

              The speed reduction shall be demonstrated according to paragraphs 6.4. and 6.5.

              At the request of the manufacturer a N1 vehicle may be assessed according to the Requirements for α >1.3 regardless of its α value.

              5.2.2. Car to pedestrian scenario

              5.2.2.1. Collision warning

              When the AEBS has detected the possibility of a collision with a pedestrian crossing the road at a constant speed of 5 km/h. a collision warning shall be provided as specified in paragraph 5.5.1. and shall be provided no later than the start of emergency braking intervention.

              The collision warning may be aborted if the conditions prevailing a collision are no longer present.

              5.2.2.2. Emergency braking

              When the system has detected the possibility of an imminent collision. there shall be a braking demand of at least 5.0 m/s² to the service braking system of the vehicle.

              The emergency braking may be aborted if the conditions prevailing a collision are no longer present

               This shall be tested in accordance with paragraph 6.6. of this Regulation.

              5.2.2.3. Speed range

              The system shall be active at least within the vehicle speed range between 20 km/h and 60 km/h and at all vehicle load conditions., unless deactivated as per paragraph 5.4.

              5.2.2.4. Speed reduction by braking demand

              In absence of driver's input which would lead to interruption according to paragraph 5.3.2., the AEBS shall be able to achieve an impact speed that is less or equal to the maximum relative impact speed as shown in the following table:

                  (a) With unobstructed crossing pedestrians with a lateral speed component of not more than 5 km/h;

                  (b) In unambiguous situations (e.g. not multiple pedestrians);

                  (c) On flat, horizontal and dry roads;

                  (d) In maximum mass and mass in running order conditions;

                  (e) In situations where the anticipated impact point is displaced by not more than 0.2 m compared to the vehicle longitudinal centre plane;

                  (f) In ambient illumination conditions of at least 2000 Lux without direct blinding sunlight.

                  (g) In absence of weather conditions affecting the dynamic performance of the vehicle (e.g. no storm, not below 0°C) and

                  (h) In absence
