Hill Hold Control (HHC)
Also known as Hill Start Assist, this feature helps drivers start safely on slopes by preventing the vehicle from rolling backward when transitioning from brake to accelerator.
How It Works:
When the driver stops on an incline and releases the brake pedal, HHC automatically holds the brake pressure for a short period (typically 2–3 seconds). This gives the driver time to press the accelerator and move forward without rollback.
Key Benefits:
- Prevents rollback on uphill roads
- Improves safety in stop-and-go traffic on slopes
- Reduces stress for new or manual transmission drivers
- Enhances confidence during uphill starts
Hill Descent Control (HDC)
HDC is a driver-assist system designed to help safely descend steep slopes by automatically controlling vehicle speed — without the driver needing to press the brake pedal.
How It Works:
When activated, HDC uses Wheel speed sensors and Braking system to maintain a low, steady speed while descending. The system individually applies brakes to each wheel as needed to ensure stability and prevent skidding, especially on loose or slippery surfaces.
Key Benefits:
- Maintains control on steep or rough downhill terrain
- Eliminates need for constant braking
- Reduces brake overheating
