ANNEX II
Requirements and tests for the type-approval of motor vehicles with regard to lane departure warnings systems
1. Requirements
1.1. General
requirements
1.1.1. The
effectiveness
of
the
lane
departure
warning
system
(LDWS)
shall
not
be
adversely
affected
by
magnetic
or
electrical fields. This shall be demonstrated by compliance with UNECE Regulation No 10 ( 1 ).
1.2. Performance
requirements
1.2.1. Whenever the system is active, as specified in point 1.2.3., the LDWS shall warn the driver if the vehicle crosses
over a visible lane marking for the lane in which it is running, on a road with a directional form that varies
between straight and a curve having an inner lane marking with a minimum radius of 250 m, when there has
been no purposeful demand to do so.
Specifically:
1.2.1.1. it shall provide the driver with the warning specified in point 1.4.1., when tested in accordance with the
provisions of point 2.5. (departure warning test) and with lane markings as specified in point 2.2.3.;
1.2.1.2. the warning mentioned in point 1.2.1. may be suppressed when there is a driver action which indicates an
intention to depart from the lane.
1.2.2. The system shall also provide the driver with the warning specified in point 1.4.2., when tested in accordance
with the provisions of point 2.6. (failure detection test). The signal shall be constant.
1.2.3. The LDWS shall be active at least at vehicle speeds above 60 km/h, unless manually deactivated in accordance
with point 1.3.
1.3.
If a vehicle is equipped with a means to deactivate the LDWS function, the following conditions shall apply as
appropriate:
1.3.1. The
LDWS
function
shall
be
automatically
reinstated
at
the
initiation
of
each
new
ignition
‘on’
(run)
cycle.
1.3.2. A constant optical warning signal shall inform the driver that the LDWS function has been deactivated. The
yellow warning signal specified in point 1.4.2. may be used for this purpose.
1.4. Warning
indication
1.4.1. The warning referred to in point 1.2.1. shall be noticeable by the driver and be provided by either of the
following:
(a) at least two warning means, to be chosen between optical, acoustic and haptic;
(b) one warning means, to be chosen between haptic and acoustic, with spatial indication about the direction of
unintended drift of the vehicle.
1.4.1.1. Where an optical signal is used for the lane departure warning, it may use the failure warning signal as specified
in point 1.2.2. in a flashing mode.
1.4.2. The failure warning referred to in point 1.2.2. shall be a yellow optical warning signal.
1.4.3. The LDWS optical warning signals shall be activated either when the ignition (start) switch is turned to the ‘on’
(run) position or when the ignition (start) switch is in a position between the ‘on’ (run) and ‘start’ that is
designated by the manufacturer as a check position (initial system (power-on)). This requirement does not apply
to warning signals shown in a common space.
1.4.4. The optical warning signals shall be visible even by daylight; the satisfactory condition of the signals must be
easily verifiable by the driver from the driver’s seat.
1.4.5. When the driver is provided with an optical warning signal to indicate that the LDWS is temporarily not
available, for example due to inclement weather conditions, the signal shall be constant. The failure warning
signal specified in point 1.4.2. may be used for this purpose.
1.5. Provisions
for
the
periodic
technical
inspection
1.5.1. At a periodic technical inspection it shall be possible to confirm the correct operational status of the LDWS by a
visible observation of the failure warning signal status, following a ‘power-ON’ (off – system OK, on – system
fault present).
( 1 ) OJ L 116, 8.5.2010, p. 1.

24.4.2012 Official
Journal
of
the
European
Union L
110/25
In the case of the failure warning signal being in a common space, the common space must be observed to be
functional prior to the failure warning signal status check.
1.5.2. At the time of type-approval, the means to protect against simple unauthorised modification of the operation of
the failure warning signal chosen by the manufacturer shall be confidentially outlined.
Alternatively, this protection requirement is fulfilled when a secondary means of checking the correct operational
status of the LDWS is available.
2. Test
procedures
2.1. The
manufacturer
shall
provide
a
brief
documentation
package
which
gives
access
to
the
basic
design
of
the
system and, if applicable, the means by which it is linked to other vehicle systems. The function of the system
shall be explained and the documentation shall describe how the operational status of the system is checked,
whether there is an influence on other vehicle systems, and the method(s) used in establishing the situations
which will result in a failure warning signal being displayed.
2.2. Test
conditions
2.2.1. The
test
shall
be
performed
on
a
flat,
dry
asphalt
or
concrete
surface.
2.2.2. The
ambient
temperature
shall
be
between
0
°C
and
45
°C.
2.2.3. V i s i b l e l a n e m a r k i n g s
2.2.3.1. The visible lane markings used in the lane departure warning tests of point 2.6. shall be one of those identified in
the Appendix to this Annex, with the markings being in good condition and of a material conforming to the
standard for visible lane markings applied in the Member State concerned. The visible lane marking layout used
for the testing shall be recorded.
2.2.3.2. The vehicle manufacturer shall demonstrate, through the use of documentation, compliance with all the other
lane markings identified in the Appendix to this Annex. Any such documentation shall be appended to the test
report.
2.2.3.3. Where the vehicle type can be equipped with different variants of the LDWS with regional specific adjustments,
the manufacturer shall demonstrate through documentation that the requirements of this Regulation are fulfilled
in all variants.
2.2.4. The test shall be performed under visibility conditions that allow safe driving at the required test speed.
2.3. Vehicle
conditions
2.3.1. T e s t w e i g h t
The vehicle may be tested at any condition of load, the distribution of the mass among the axles being that
stated by the vehicle manufacturer without exceeding any of the maximum permissible mass for each axle. No
alteration shall be made once the test procedure has begun. The vehicle manufacturer shall demonstrate through
the use of documentation that the system works at all conditions of load.
2.3.2. The vehicle shall be tested at the tyre pressures recommended by the vehicle manufacturer.
2.3.3. Where the LDWS is equipped with a user-adjustable warning threshold, the test as specified in point 2.5. shall be
performed with the warning threshold set at its maximum lane departure setting. No alteration shall be made
once the test procedure has begun.
2.4. Optical
warning
signal
verification
test
With the vehicle stationary check that the optical warning signal(s) comply with the requirements of point 1.4.3.
2.5. Lane
departure
warning
test
2.5.1. Drive the vehicle at a speed of 65 km/h +/- 3 km/h into the centre of the test lane in a smooth manner so that
the attitude of the vehicle is stable.
Maintaining the prescribed speed, gently drift the vehicle, either to the left or the right, at a rate of departure of
between 0,1 and 0,8 m/s so that the vehicle crosses the lane marking. Repeat the test at a different rate of
departure within the range 0,1 and 0,8 m/s.
Repeat the above tests drifting in the opposite direction.

2.5.2. The LDWS shall provide the lane departure warning indication mentioned in point 1.4.1. at the latest when the
outside of the tyre of the vehicle’s front wheel closest to the lane markings crosses a line 0,3 m beyond the
outside edge of the visible lane marking to which the vehicle is being drifted.
2.6. Failure
detection
test
2.6.1. Simulate a LDWS failure, for example by disconnecting the power source to any LDWS component or discon
necting any electrical connection between LDWS components. The electrical connections for the failure warning
signal of point 1.4.2. and the LDWS disable control of point 1.3. shall not be disconnected when simulating a
LDWS failure.
2.6.2. The failure warning signal mentioned in point 1.4.2. shall be activated and remain activated while the vehicle is
being driven and be reactivated after a subsequent ignition ‘off’ ignition ‘on’ cycle as long as the simulated failure
exists.
2.7. Deactivation
Test
2.7.1. If the vehicle is equipped with means to deactivate the LDWS, turn the ignition (start) switch to the ‘on’ (run)
position and deactivate the LDWS. The warning signal mentioned in point 1.3.2. 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 LDWS has been
reinstated as specified in point 1.3.1. If the ignition system is activated by means of a ‘key’, the above
requirement shall be fulfilled without removing the key.
