4-5 Driving assistance function
Driving safety system
In order to improve the driving safety, the following driving safety system will automatically
will be operated automatically based on various driving conditions. However, keep in mind
that these systems are only used to provide the assist functions and should not be overly
dependent during driving process.
ESP (Electronic Stability Program)
The ESP integrates the ABS, VDC, and TCS functional modules as well as HHC, HBA, CDP,
and HDC value-added sub-functions.
VDC (Vehicle Dynamic Control)
When the car turns suddenly during driving, VDC system can determine the driving intention
based on the information, such as the steering wheel rotation angle and the driving speed,
and compare continuously them with the actual situation of the car; if the car is deviated
from the normal driving route, VDC can be used to correct the route by braking the
corresponding wheels to help the driver to control the slipping and maintain the driving
stability of the car.
TCS (Traction Control System)
TCS is used to prevent the drive wheels from slipping during acceleration by reducing the
motor power, if necessary, it can be used to apply a braking force for control to prevent the
drive wheels from slipping. TCS can be used to ensure that the car is easily started,
accelerated and climbed under adverse driving conditions.
Warning
■ In the following cases, TCS may not be operated effectively:
● When driving on slippery roads, even if the TCS system is operated normally, it
may not be able to control the direction and achieve the power requirements;
● Do not drive the car in the conditions where the stability and power may be lost.
Hill-Start Hold Control (HHC)
After the release of brake pedal, the HHC can maintain the braking pressure applied by the
driver for 1s to prevent the backward gliding of vehicle.
