STARTING AND DRIVING
If the speed difference is higher than 40km/h, then the AEB cannot avoid
the collision automatically. To completely avoid the collision in this
situation, the driver shall apply the brake in advance.
The AEB shall not be the reason for the driver to change
the driving style at will. If the driver totally relies on the
AEB, a collision will happen sooner or later.
Enable FCW and AEB
Set in the vehicle state mode in entertainment system: Vehicle State
Mode → Vehicle Control → Driving Assist; Options: OFF/Alann/Alann +
Auto braking.
The FCW and AEB perform three procedures in the sequence below:
1 Collision Warning
First warn the driver of a possible collision. The FCW can detect
stationary vehicle or vehicle moving in the same direction before
the driver's vehicle. When there is a risk of collision with other
vehicles, the vehicle will alert the driver via the blinking "FCW/AEB
Warning Lamp (yellow)” acoustic signal and mild tactile
warning in the form of cadence braking. For low speed, emergency
braking or acceleration, no tactile warning is provided.
2 Brake Support
If the risk of collision has already escalated, then the auxiliary brake
will be enabled. If the system thinks the braking force is not sufficient
to avoid the collision, it will strengthen the braking force of the
FCW and AEB
The FCW alerts the driver of the front vehicle by visual and acoustic
signals. If the driver fails to take actions within a rational time, the system
will trigger the AEB automatically.
The FCW can prevent collision or decrease collision speed, providing
aid when there is a risk of collision with other vehicles. The AEB is an
auxiliary function which helps the driver to avoid collision at traffic jams,
for example, when an accident may occur due to change of the front
traffic or distraction. When a collision is going to happen, the function
can provide aid for the driver by applying the brake automatically when
the driver does not apply the brake and/or when he/she does not avoid
an obstacle due to slow action.
The AEB provides short, quick braking and it stops the vehicle under
normal situations, exactly behind the front vehicle. For most of the
drivers, this is not a normal driving style, so they may feel uneasy.
The AEB is enabled only when the driver applies the brake in advance,
therefore, it cannot help the driver in all cases. To avoid unnecessary
intervention, the design of the AEB requires late initiation.
Normally, the driver or passenger notices the AEB only when a collision
is coming.
The AEB can decrease the vehicle speed to 40km/h at most, this avoids
collisions with the front vehicle.
STARTING AND DRIVING
When the AEB is enabled and the brake is applied, the "FCW/AEB”
Warning Lamp (red)" on the instrument cluster will
illuminate, and it will send an acoustic alarm to indicate that the
function is enabled or has been initiated.
3 Auto Braking
The auto braking is enabled at the final step. In this case, if the driver
still does not take any anti-collision action, and a collision is going to
happen, then the auto braking will be triggered. This happens
whether the driver applies the brake or not. Apply the maximum
braking force to reduce collision speed, or apply a limited braking
force sufficient to avoid a collision. When the AEB successfully
avoids a collision with the static object, the vehicle will come into a
standstill to expect for the driver's action. In the event that the slow
speed of the front vehicle causes the vehicle to stop, the vehicle
speed will be decreased to the same level as the front vehicle. The
driver can stop the brake intervention by depressing the accelerator
When AEB applies the brake, the brake lamps illuminate
The AEB is just an auxiliary function, so it cannot a work
under all driving conditions, traffic, weather and road
conditions. The alarm Is triggered only when a collision Is
likely to happen. Before using the AEB, the driver shall
read this section to understand the specified restrictions.
The auto braking function of the AEB can prevent
collision or decrease collision speed. To ensure a full bra
kl ng performance, the driver shall always depress the
brake pedal, even for auto braking.
The AEB wlll not enable the auto braking option under
heavy acceleration. The driver shall always keep a
correct distance and speed, and never wait the system to
send a collision warning or the AEB takes an
Sensitivity Setting of FCW
With the FCW enabled, set the sensitivity.
Set in the vehicle state mode in entertainment system: Vehicle State
Mode → Vehicle Control → Driving Assist; Options: High/Medium/Low.
The sensitivity determines the warning distance of the system and
controls the distance triggered by visual, acoustic and tactile warnings. If
the warning is excessive or it disturbs the driver, reduce the sensitivity.
This will cause the system warning to occur later and the number of the
warning to be decreased.
