120 Driving and Controls
Electric Brake Force Distribution (EBD) System
The EBD system uses the high-speed computer to
respectively induce and calculate different ground to which
four wheels are attached, and thus calculate different friction
values at the moment the vehicle brakes. Therefore, four
wheels can be able to brake in different ways and force
based on different conditions, and can be adjusted fast
during movement, so as to ensure that the vehicle is stable
and safe.
Electronic Stability Control (ESC) System
The ESC system is a new-type active safety system,
representing the further development of the functions of
anti-lock brake system (ABS) and traction control system
(TCS). In addition, the yaw rate sensor, lateral acceleration
sensor and steering wheel turn angle sensor are added. The
driving force and braking force of front and rear, left and right
wheels are controlled through the ECU, which ensures the
lateral stability of the vehicle. When the driver operates the
vehicle beyond the limit values, in case of turning at high
speed, the ESC system automatically intervenes to ensure
that the vehicle returns to be controllable and ensure the
safety. Indicators relevant to the ESC system consist of ABS
MIL, EBD MIL, ESC MIL and ESC OFF indicator.
1.
Indicators illuminate for self-check when the ignition
switch is connected. The 4 indicators are normally on
for 3s, indicating that the ESC system is conducting
self-check and indicators work normally. The 4
indicators go out 3s later under the normal condition.
When faults (such as neglected installation, loosened
connector, abnormal CAN communication) exist on
the ESC system, only the ESC OFF lamp will go out
3s later, and other 3 lamps are normally on.
2. In the process of driving the vehicle, if the ESC
function is activated, the ESC lamp will flicker, telling
the Owner that the ESC system is working. If the ESC
system functions abnormally but the ABS+EBD
system functions normally, the ESC lamp is normally
on, indicating that the ESC system gets faulted. If the
ESC system and the ABS function abnormally and the
EBD system functions normally, the ESC lamp and
the ABS lamp are normally on. If the ESC system, the
ABS and the EBD system function abnormally, the
ESC lamp, the ABS lamp and the EBD lamp are
normally on.
3. The ESC OFF lamp is used to indicate that the ESC
function is disabled (the lamp will be normally on so
long as the ESC function is disabled; the lamp will go
out if the function is enabled). If the Owner presses
the ESC OFF switch, some ESC functions will be
disabled, and the ESC OFF lamp illuminates. When
the switch is pressed, the ESC system is working, and
the ESC function will not be disabled immediately and
will be disabled after the work is over. If the Owner
presses the ESC switch again, all functions will be
enabled again. If the pressed time of ESC switch
exceeds 10s, the ESC system will consider it as one
incorrect operation (for example, the switch is pressed
by one unknown article incautiously), the ESC
function will not be disabled.
4. The ESC system will be activated automatically after
every re-ignition.
Note
The ESC system may not be able to help you escape
from out-of-control in the ultimate state for sure.
Therefore, take care during daily driving. You had
better disable the ESC system when crossing country
on a sandy and rocky pavement. As it is time for the
ESC system to function on an icy, snowy and slippery
pavement, the ESC system shall not be disabled.
ESC OFF Switch
Press the ESC OFF switch after starting the vehicle, and the
ESC OFF lamp on the instrument cluster illuminates and
some ESC functions are disabled. Press the ESC switch
again, the ESC function is enabled again and the ESC OFF
lamp on the instrument cluster goes out.
