   ‘type of vehicle with regard to its advanced emergency braking system’ (AEBS) means a category of vehicles which do not differ in essential respects, including as to:

   1. (a)

      the manufacturer’s trade name or trade mark;

   2. (b)

      vehicle features which significantly influence the performances of the AEBS;

   3. (c)

      the type and design of the AEBS;

2. (2)

   ‘subject vehicle’ means the vehicle being tested;

3. (3)

   ‘target’ means a high volume series production passenger car of category M₁ AA saloon as defined in point 1 of Section C of Annex II to Directive 2007/46/EC or, in the case of a soft target, an object representative of such a vehicle in terms of its detection characteristics applicable to the sensor system of the AEBS under test;

4. (4)

   ‘soft target’ means a target that will suffer minimum damage and cause minimum damage to the subject vehicle in the event of a collision;

5. (5)

   ‘moving target’ means a target travelling at a constant speed in the same direction and in the centre of the same lane of travel as the subject vehicle;

6. (6)

   ‘stationary target’ means a target at standstill facing the same direction and positioned on the centre of the same test lane of travel as the subject vehicle;

7. (7)

   ‘collision warning phase’ means the phase directly preceding the emergency braking phase, during which the AEBS warns the driver of a potential forward collision;

8. (8)

   ‘emergency braking phase’ means the phase starting when the AEBS emits a braking demand for at least 4 m/s² deceleration to the service braking system of the vehicle;

9. (9)

   ‘common space’ means an area on which two or more information functions may be displayed, but not simultaneously;

10. (10)

    ‘self-check’ means an integrated function that checks for a system failure on a semi-continuous basis at least while the system is active;

11. (11)

    ‘time to collision (TTC)’ means the value of time obtained by dividing the distance between the subject vehicle and the target by the relative speed of the subject vehicle and the target, at an instant in time.
