If driving in the hills sounds like something you’d like to try, it’s essential for you to learn of the workings of an important driving feature known as the hill descent control system. There is a significant difference in driving on level roads versus hills.
Operating the clutch, brake, and acceleration is a manageable task on city roads. However, driving on hilly or mountainous terrains requires precision. The inclined, slippery, and narrow tracks demand complete attention as the driver navigates steep turns and maintains vehicle balance.
This is where the hill descent control system proves invaluable. It is a driver-assistance feature that uses traction control technology combined with anti-lock brakes. The system continuously adjusts braking pressure to maintain a specific speed and help prevent slippage while descending a steep surface.
Let’s take a closer look at how this system works, its applications, and its benefits.
How does Hill Descent Control Work?
If you frequently travel to hilly regions, then you should invest in cars with hill descent control systems. As an advanced feature integrated into newly manufactured cars, the hill descent control (HDC) has revolutionised the driving experience on rough and steep terrains.
HDC is a low-speed technology that can be activated when your car needs to move slower than 24 to 32 km/h. Once activated and the maximum speed is set, the system uses traction control and an anti-lock braking system (ABS) to prevent tyres from slipping while descending.
The system maintains traction by locking and releasing each wheel as necessary. This allows you to focus solely on steering, as the system handles the car’s speed while ascending or descending a steep slope.
How to Use Hill-Descent Control?
For safety purposes, it is vital to activate this system at the right time. Here’s a breakdown on how it is applied:
- In the cars with hill descent control feature, you can mostly find the HDC button on the left side of the vehicle’s steering wheel, below the instrument cluster or on the centre console. However, the location of the HDC switch can vary according to manufacturer and car’s model.
- Whenever you need to drive your car on a steep slope, uneven terrain, or slippery surface, you should press the HDC switch to activate the system. Remember that the HDC system works when your car is in reverse or forward gear.
- Anti-lock brakes are used by the HDC system to maintain your car’s speed automatically.
- You don’t have to touch the accelerator or brakes to control each wheel’s speed. The vehicle will accelerate, and the hill descent control system will simultaneously apply the brakes to gently slow down your car’s speed during incline and decline.
- Finally, as soon as you reach the levelled road surface, you can turn off the hill descent control system and drive forward at normal speed.
Uses of Hill-Descent Control
Now that you are familiar with the working of hill descent control systems, it’s crucial to understand when, how, and why to use them.
When to Use Hill-Descent Control?
You can use the hill descent control feature in the following scenarios:
- Whenever you are driving on steep inclines or declines, such as off-road trails or mountain roads
- When driving on uneven terrain that has various elevation changes.
- To drive safely on slippery or loose surfaces, such as snow, mud, or gravel.
Why to Use Hill-Descent Control?
Is it so necessary to use the hill descent control system? Let’s learn why you should use the HDC system in your car:
- Enhanced Safety: By regulating your car’s speed, hill descent control can help prevent it from accelerating uncontrollably. You don’t have to worry about your car skidding or losing traction when driving on uneven, steep, or slippery surfaces.
- Better Brake System Management: By integrating the HDC system into cars, wear and tear on the braking components has been significantly reduced. Manual intervention usually overheats or damages the brakes. This system automatically distributes braking force evenly, which decreases wear and tear on brake discs and pads.
- Prevents Driver Fatigue: Stepping on brakes continuously during long descents can be exhausting. With the HDC feature, you don’t have to constantly press the pedal, reducing fatigue and ensuring a more relaxed and comfortable drive on prolonged downhill stretches.
- Enhances Performance: The hill descent control feature optimises the traction and stability of your car, allowing it to navigate challenging terrains smoothly.
- Supports Heavy Loads: Driving downhill is already risky. But the risk increases much more when driving a fully loaded car. HDC can help you manage your vehicle’s additional weight by preventing momentum from overpowering the brakes.
Conclusion
Having a car equipped with a hill descent control system makes navigating steep slopes, uneven terrains, and slippery surfaces effortless. Therefore, make sure to activate the HDC system when heading to the hills.
