Latest update date: February 25, 06

Cross-slope derailleur is an important driving technique that every driver needs to master, especially when driving on mountainous terrain or steep roads.

According to statistics from the Vietnam Register, about 15% of new driving-related accidents occur when the derailleur is on a slope.

This technique requires smooth coordination between basic operations such as controlling the accelerator pedal, brake pedal, clutch pedal (for manual transmission vehicles), and gear lever. If done properly, it will help the vehicle start safely on an inclined surface without slipping backwards, while also protecting the vehicle's transmission system.

Factors to pay attention to include the slope of the road surface, surface condition (dry, wet, slippery), vehicle weight, and engine power. In addition, mastering this technique also helps drivers be more confident when driving in difficult situations, contributing to improving traffic safety. Below are the 4 most effective methods to safely and professionally perform cross-hill derailleurs:

Use the handbrake (Emergency Brake)

Handbrake, also known as emergency brake, is the method most favored by many drivers due to its high efficiency and safety. This is especially useful for new drivers when they need to park their car on a steep hill. The procedure is as follows:

  • When the vehicle is stopped on a slope, pull the handbrake to keep the vehicle stationary.
  • Switch your foot from the foot brake to the accelerator.
  • Cut the clutch into gear and release the clutch, stepping on the accelerator as if starting normally on a flat road.
  • Continue to release the clutch and gently step on the accelerator until you feel the car start to move.
  • Lower the handbrake (still holding the throttle) to move the car forward.

Advantages: This method helps prevent the car from drifting backwards, creating confidence for new drivers.

Combine accelerator and clutch

This method requires smooth coordination between the accelerator and clutch pedal:

  • Release the clutch halfway until the car vibrates as if it wants to move forward.
  • Quickly release the brake pedal and switch to the accelerator.
  • Gently step on the accelerator to slowly move the car forward.

Note: This method requires delicate controls and may be difficult for new drivers.

Right toe and heel technique

This is an advanced technique, not popular with everyone because it depends on the vehicle design and the size of the driver's feet:

  • The left foot is cutting the taper.
  • Right foot steps on the brake.
  • Turn your right foot horizontally so that your heel gently presses on the accelerator.
  • When you have enough throttle, release the clutch and brake to let the car move.

Advantage: This technique allows simultaneous control of both the brake and the throttle, making the derailleur smoother.

Taper technique

This technique should only be applied when stopping on a slope for a short time:

  • Combine to produce a moderate taper.
  • At the same time, apply the gas (if necessary) just enough.
  • Keep the vehicle with enough traction to not drift but also not move forward.

Warning: Applying this technique for a long time can cause rapid cone wear due to high friction and heat generation.

Note:

  • Practice regularly: Find a safe slope and practice the slope many times to improve your skills.
  • Stay calm: Stress can reduce vehicle control. Breathe deeply and focus on each step.
  • Use assistive technology: Many modern cars are equipped with a hill start assist system (Hill Start Assist), making it easier to park.

Hilly derailleurs are an important skill that every driver needs to master. By applying the above methods and practicing regularly, you will quickly improve this skill, ensuring safety for yourself and other road users. Remember, each method has its own pros and cons, so choose the one that works best for you and practice until you master it.

Frequently asked questions (FAQ)

1. What is a cross-hill derailleur and why is it important?

A hill-side derailleur is a technique for starting and moving a vehicle from a stationary state on a sloping road surface. This skill is very important because it helps ensure safety when driving in hilly terrain or steep streets. According to statistics, about 15% of accidents involving new drivers occur when the derailleur is on a slope.

2. What methods are recommended for new drivers?

The method of using the handbrake is most recommended for new drivers because it is safe and easy to do. About 80% of driving schools in Vietnam instruct students to use this method first.

3. How long is the time allowed to complete a cross-hill depa?

According to the regulations of the Vietnam Register, the time allowed to complete a steep hill is 30 seconds.

4. How far is the vehicle allowed to back up when performing a steep hill shift?

When putting the brakes on, the vehicle must not move back more than 50cm from the original position to ensure safety.

5. What is the maximum speed after a successful derailleur?

After successful de-padding, the vehicle speed must not exceed 24 km/h for classes B and D.

6. How to practice cross-hill derailleurs safely?

To practice safely, choose a slope with a slope of about 5-10 degrees, with little traffic. Start with a low incline and gradually increase. Always have an instructor accompany you during the workout.

7. Why should you not abuse the taper technique?

Overuse of taper tightening techniques can cause rapid cone wear due to high friction and heat generation. According to experts, using this technique continuously for 5 minutes can reduce the life of the clutch by up to 20%.

8. Is there any difference between hill derailleurs on manual and automatic transmission vehicles?

There is a significant difference. Automatic transmission cars are often easier to use on steep slopes because they do not need to operate the clutch. However, accelerator control technique is still very important. About 85% of modern automatic cars are equipped with a hill start assist system.

9. How to fix the situation when the vehicle drifts when the derailleur is on a slope?

If the vehicle drifts, quickly step on the brakes and pull the handbrake. Then, restart the derailleur process from the beginning. Statistics show that 90% of cases where the vehicle drifts when the brake is on are due to the driver not controlling well the timing of releasing the brake and stepping on the accelerator.

10. What are some common mistakes when doing cross-hill derailleurs?

Common errors include:

  • Releasing the brake too quickly (accounts for 40% of errors)
  • Acceleration too hard (30%)
  • Not keeping the steering wheel straight (20%)
  • Forgot to lower the handbrake (10%)

11. How to set the derailleur uphill when it rains or the road is slippery?

When the road is slippery, use the handbrake method and increase the brake holding time by 1-2 seconds. Step on the accelerator more gently than usual, about 70% of the normal level. If so, activate the vehicle's driving mode for slippery roads.

12. How to maintain downhill derailleur skills?

To maintain your skills, practice at least once a month, even if you are an experienced driver. Participate in training courses to improve safe driving skills, including 20-30% of the time spent on hill-crossing derailleur techniques and handling emergency situations on steep roads.
