Kia Sportage: Assist Emergency Braking(AEB) System / Description and operation
| – |
AEB system is designed to help avoid a potential collision or reduce
its impact when drivers applies inadequate, delayed or no brakes at
all to avoid a collision.
|
| – |
The system detects the risk factors on the road by using the frontal
impact sensor and warn the driver and activate the emergency brake to
prevent collision or reduce collision speed.
|
The following is the system control process
| 1. |
Detect preceding vehicles (pedestrians) and analyze the data (CAN comm.)
by using the radar sensor of the Smart Cruise Control System (SCC) and
the camera sensor of Lane Departure Warning System (LDWS).
|
| 2. |
Confirm the object to be protected by AEB system (vehicles and pedestrians)
by using the analyzed data.
|
| 3. |
Calculate the speed reduction depending on the speed, distance, existence
or nonexistence of preceding vehicle.
|
| 4. |
Report the "required speed reduction" to Vehicle Dynamics Control (VDC)
(CAN Comm.)
|
| 5. |
VDC performs automatic control after calculating the required torque
to achieve "required speed reduction" (CAN Comm.).
|
※ The time indicated will be changed according to vehicle speeds.
| • |
Step 1: Issue a visual (display) and vocal alarm when a danger is detected.
|
| • |
Step 2: Reduce engine torque and activates AEB when there is a high
chance of collision.
|
| • |
Step 3: Activate emergency brake when a collision is imminent.
|
| • |
After stopping the vehicle: Maintain the braking control for a certain
time and then release it.
|
| • |
Braking power is adjusted depending on the risk levels of collision,
but it is released immediately when it detects the driver's
action to avoid a collision.
|
| 1) |
When it exceeded the maximum operation speed.
|
| 2) |
When it detected driver's action to avoid a collision such as
sudden steering changes.
|
| 3) |
When the shift lever is in R or P
|
| 4) |
When you pressed the accelerator pedal half way.
|
|
| 1) |
When you drive at 80km/h or faster, the system does not go to
step 3 of emergency braking.
|
| – |
Full auto braking is not available.
|
| 2) |
While driving at 80km/h or slower on a straight or slightly
curved road, the system performs three steps after issuing a
warning.
|
| – |
But a collision may occur at 30km/h or faster depending on the
road conditions.
|
| 3) |
While driving at 80km/h or slower on a straight or slightly
curved road, after a visual and vocal warning, AEB is activated
to reduce the vehicle speed.
|
| 4) |
At 80km/h or faster, it's impossible to avoid a collision. Offset
should be less than 50%.
|
| 5) |
AEB does not work on the vehicles backing up or resisting.
|
| 6) |
At 70km/h or faster, it does not respond to pedestrians.

Offset : Rate of non-overlapping on the line between the front
driving car and my car

| 1) |
Offset 0% :

Description
Evaporative Emission Control System prevents fuel vapor stored in fuel tank
from vaporizing into the atmosphere. When the fuel evaporates in the fuel tank,
the vapor passes through vent hoses or tubes to the canister filled with charcoal
and the canister temporar ...
