Driver Assis t Syst em (D AS)
The functions associated with the electronic stability control (ESC) system vary
slightly depending on the model. In order to improve the driving safety and
performance of the vehicle, each of the following functions will work automatically
according to various driving conditions. However, it is important to remember that
these functions are only auxiliary and should not be relied upon when driving the
vehicle.
◼
Anti-lock Braking System (ABS)
When driving on slippery roads or during emergency braking, it prevents the wheels from
locking and producing side-slip or runaway.
◼
Electronic Brakeforce Distribution (EBD)
According to the changes of vehicle load, road condition and braking force, the dynamic
proportional distribution of front and rear wheel braking force is implemented to improve
vehicle braking stability and controllability.
◼
Traction Control System (TCS)
It prevents the drive wheels from slipping when the vehicle starts or accelerates on a
smooth road, ensuring vehicle acceleration performance.
◼
Hydraulic Brake Assist (HBA)
Braking force compensation is performed when the brake pedal is depressed quickly,
which can effectively increase the braking force.
◼
Hydraulic Brake Boost (HBB)
Braking force compensation is required when the assistance provided by EPS is
insufficient, which can effectively increase the braking force.
◼
Hill descent control (HDC)
When the vehicle is running downhill at a speed of 8-35 km/h, apply the proper braking
force to the wheels to keep the vehicle at a stable speed. You can set the on/off of HDC
by HDC button.
◼
Hill Hold Control (HHC)
This function properly maintains the braking pressure applied by the driver to prevent the
vehicle from skidding during the period of time when the driver moves his foot from the
brake pedal to the accelerator pedal when the vehicle is starting on a hill.
◼
Electronic Stability Control (ESC)
It helps the driver control sideslip and ensure correct vehicle trajectory when steering
suddenly or steering on slippery roads.
◼
Controlled Deceleration for ACC-Stop & Go (CDD-S)*
It assists adaptive cruise control (ACC) to achieve adaptive cruise deceleration control of
the vehicle.
◼
Controlled Deceleration for Parking Brake (CDP)
Pull up and hold the EPB switch, and the vehicle actively enters the deceleration state.
◼
AUTO HOLD
A function to hold the stationary vehicle via the parking brake applied by the hydraulic
system for a short period of time, after which the parking is taken over by the electronic
parking system.
◼
Automatic Brake Prefill (ABP)
ESC system actively pre-charges the brake system according to the request from the
relevant controller to improve the response speed of the brake.
