5. Driving Directions
5.3.6
Hill Hold Control (HHC)
HHC allows the driver to easily move his/her
foot from the brake pedal to the accelerator pedal
when starting on slopes without using the parking
brake to avoid sliding accidents.
Activation Conditions for HAC
–
HHC function is activated to apply braking
pressure
to
vehicle
with
pressure
maintenance time of 1 second, if the driver
loosen the brake pedal in following condition:
When ramp slope is more than 4%, the shift
lever is not in "P" or "N" gear, EPB is not
applied, the driver depresses on the brake
pedal to stop the vehicle and the vehicle is in
static state.
–
During the working time of HHC, when the
engine torque exceeds the vehicle resistance
torque, the braking pressure will be released
and the activation will be completed
successfully.
–
HHC also works when the vehicle goes
downhill and the shift lever is switched to “R”
gear.
Hint
•
The HHC will apply a brakeforce automatically
when starting on a steep uphill or shifting to
reverse gear on downhill, to prevent slipping.
•
HHC is integrated on the ESP system. If the
HHC fails, the ESP indicator light will be on
and graphic prompt will appear on the
instrument cluster display accordingly.
