What does Hill Descent Control (HDC) mean?
1 Answers
Hill Descent Control (HDC), also known as the slope control system, enables drivers to smoothly navigate steep downhill sections without pressing the brake pedal while maintaining full control. Below is more information about descending steep slopes: 1. Low Gear: The L gear in a car stands for L-Low. When going downhill or descending a long slope, shifting to this gear restricts the car's automatic transmission to the lowest gear (equivalent to first gear in a manual transmission car), allowing the vehicle to use engine braking during descent. This prevents the driver from having to press the brakes for extended periods, which could lead to brake pad overheating and potential hazards. 2. Braking Function: In this gear, the transmission remains in 1st gear without shifting up, which can be used on slopes and other similar conditions. It also provides some braking function during downhill driving.
