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 HHC
●
HHC function is activated to apply braking
pressure to vehicle with pressure
maintenance time of 1 second, if the driver
loosens the brake pedal in following
conditions: When ramp slope is more than
4%, the shift lever is not in “P” or “N” gear,
EPB is not applied, and 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
●
When the HHC will be integrated with
braking function automatically to
prevent sliding on the steep rampway
or when the shift lever is switched to
downhill reversing gear.
●
HHC is integrated on the ESP system. If
the HHC fails, the ESP indicator light is
illuminated and the relevant hints are
displayed on the instrument cluster
display.
