2.5. Warning and activation test with a moving target U.K.

• For approval level 1: Column H of the table in Appendix 1

• For approval level 2: Column H of the table in Appendix 2

The separation distance between the subject vehicle and the moving target shall be at least 120 m.

From the start of the functional part of the test until the subject vehicle comes to a speed equal to that of the target there shall be no adjustment to any subject vehicle control by the driver other than slight steering adjustments to counteract any drifting.

Textual Amendments

F2 Deleted by Commission Regulation (EU) 2015/562 of 8 April 2015 amending Regulation (EU) No 347/2012 implementing Regulation (EC) No 661/2009 of the European Parliament and of the Council with respect to type-approval requirements for certain categories of motor vehicles with regard to advanced emergency braking systems.

2.5.4. The emergency braking phase shall not start before a TTC equal to or less than 3,0 seconds. U.K.

Compliance shall be verified by either actual measurement during the test or using documentation provided by the vehicle manufacturer, as agreed between the Technical Service and the vehicle manufacturer.

2.6. Failure detection test U.K.

2.6.1. Simulate an electrical failure, for example by disconnecting the power source to any AEBS component or disconnecting any electrical connection between AEBS components. When simulating an AEBS failure, neither the electrical connections for the driver warning signal referred to in point 1.5.4 nor the optional manual AEBS deactivation control referred to in point 1.4 shall be disconnected. U.K.

2.6.2. The failure warning signal referred to in point 1.5.4 shall be activated and remain activated not later than 10 seconds after the vehicle has been driven at a speed greater than 15 km/h and be reactivated immediately after a subsequent ignition ‘off’ ignition ‘on’ cycle with the vehicle stationary as long as the simulated failure exists. U.K.

2.7. Deactivation test U.K.

2.7.1. For vehicles equipped with means to deactivate the AEBS, turn the ignition (start) switch to the ‘on’ (run) position and deactivate the AEBS. The warning signal referred to in point 1.4.2 shall be activated. Turn the ignition (start) switch to the ‘off’ position. Again, turn the ignition (start) switch to the ‘on’ (run) position and verify that the previously activated warning signal is not reactivated, thereby indicating that the AEBS has been reinstated as specified in point 1.4.1. If the ignition system is activated by means of a ‘key’, that requirement shall be fulfilled without removing the key. U.K.

2.8. False reaction test U.K.

2.8.1. Two stationary vehicles, of category M₁ AA saloon, shall be positioned: U.K.

(a)

so as to face in the same direction of travel as the subject vehicle;

(b)

with a distance of 4,5 m between them(2);

(c)

with the rear of each vehicle aligned with the other.

2.8.2. The subject vehicle shall travel for a distance of at least 60 m, at a constant speed of 50 ± 2 km/h to pass centrally between the two stationary vehicles. U.K.

During the test there shall be no adjustment of any subject vehicle control other than slight steering adjustments to counteract any drifting.

2.8.3. The AEBS shall not provide a collision warning and shall not initiate the emergency braking phase. U.K.

(1)

The identification characteristics of the soft target shall be agreed upon between the Technical Service and the vehicle manufacturer as being equivalent to a passenger car of category M₁ AA saloon.

(2)

The point of reference of each stationary vehicle for establishing the distance between the two stationary vehicles, shall be determined in accordance with ISO 612: 1978.
