1) Speed available in HDC mode (slope)
2H/4H mode: vehicle speed below 50 km/h
Forward
(operation slope level: 10%, termination slope level: when it reaches 8%)
driving
4L mode: vehicle speed below 25 km/h
(operation slope level: 10%, termination slope level: when it reaches 5%)
2H/4H mode: vehicle speed below 50 km/h
(operation slope level: 8%, termination slope level: when it reaches 5%)
Reverse
driving
4L mode: vehicle speed below 25 km/h
(operation slope level: 8%, termination slope level: when it reaches 4%)
2) HDC target speed in 2H/4H mode
(The HDC target speed is the speed that the HDC is not terminated even after the vehicle speed
reaches 7 km/h, but is converted to the stand-by mode. When the vehicle speed increases again
as a result of the increase of the road steepness, etc., the HDC goes into operation.)
Forward driving: 7 km/h
Reverse driving: 7 km/h (automatic transmission), 8.5 km/h (manual transmission)
3) HDC target speed in 4L mode
Forward and reverse driving: 3 km/h
5. Vehicle position control function in ESP and HBA function are not in
operation:
The HDC is the device to improve the engine brake effect during downhill driving on a steep hill.
If the ESP function is in operation, HDC operation is overridden.
6. Slope level exceeds 10%.
When the slope level exceeds 10%, the HDC operates until the vehicle reaches the speed
value given in step (4).
▶ When the slope level is between 10% and 20% during the HDC operation
When depressing the accelerator pedal or brake pedal, HDC system is changed to stand-by
mode. When depressing the accelerator pedal again, HDC starts its operation again. Therefore,
drivers can control the vehicle speed to a desired level by operating the accelerator pedal.
▶ When the slope level exceeds 20% during the HDC operation
When depressing the accelerator pedal, HDC system is changed to stand-by mode.
When depressing the brake pedal, HDC continues its operation and the braking power is
increased.
In this case, HECU sounds an abnormal noise and brake pedal may be very rigid, but this is a
normal condition due to HDC operation.
