▶ Detects the position of the shifting lever for the HDC operation among ABS/ESP
functions.
It is used for the second item of the 6 operation conditions of the ABS/ESP's HDC function.
Please refer to the ABS/ESP section for the specific information related to the HDC.
- HDC Operation switch ON
- Forward/Reverse Shifting lever location
Manual transmission: operates in the 1st gear or reverse gear position
·
Automatic transmission: possibly operates except in the P (parking) or N (neutral) position.
·
- The vehicle with the manual transmission does not have a separate device or switch that
detects the 1st gear. It only detects the forward/reverse direction of the vehicle through the
back-up light switch and the neutral switch, and cannot solely detect the 1st gear position.
The reason for noting the 1st gear above, though the HDC also operates in the 2nd gear
position, is because the engine may turn off during the HDC operation process. You may
face a very dangerous situation if the engine turns off at a steep hill.
- The HDC aids the slowdown of the vehicle when driving down a steep hill and cannot
sufficiently decelerate only with the engine brake. Thus, a driver must operate the HDC
only in the 1st gear when driving a vehicle with the manual transmission.
- When not depressing the accelerator pedal or brake pedal.
- The vehicle speed is above 7 km/h
(based on the automatic transmission/4H drive mode).
- The ESP's vehicle position control function and HBA function are not in operation.
The HDC is added to aid drivers when driving down the hill, but when any basic
·
function of the ESP is in operation prior to the HDC system operation, the ESP takes
priority over the HDC.
- The inclination of the driving road exceeds 10%.
· When the inclination of the driving road exceeds 10%, the HDC operates until the
vehicle reaches the speed condition given in step 4).
When the Inclination is 10% ~ 20% During the HDC Operation
When depressing the accelerator pedal or brake pedal, it converts to the stand-by mode, and
when depressing the accelerator pedal again, the HDC operates again. Therefore, driver may
maintain a desired speed by repeating this depressing and releasing process of the accelerator
pedal.
When the Inclination Exceeds 20% During the HDC Operation
When depressing the accelerator pedal, it converts to the HDC operation stand-by mode.
When depressing the brake pedal, the HDC operation state is maintained and the braking
power is enhanced.
In this case, the HECU emits an abnormal noise and the brake pedal may feel very rigid, but
this is a normal occurrence resulted from the HDC operation.
(does not operate in the neutral position).
