How do I drive uphill or downhill?

Uphill and downhill both need to be in low gear. Uphill, if the slope is not big and you don't feel heartache, try to go uphill and try to keep the semi-clutch state, so that the car always maintains momentum and does not slip, and the slope is large and often stop-and-go, it is best to use the handbrake to start the car. Downhill, the brake must be mastered, as long as the car has speed, try not to step on the clutch, and suddenly turn off the handbrake must quickly pull up.

According to the operating procedures, it is necessary to reduce the gear in turn, when the gear is lowered to the lowest gear, the speed of the car has slowed down, and then step on the clutch, brake, pull over, pull the handbrake after the car stops, turn off, and hang the gear to the reverse gear.

If you are more proficient in driving, you can directly hang the neutral brake, pull over, pull the handbrake, turn off the engine, and hang the reverse gear. No need to downshift.

The key to the uphill start of the car is to overcome the uphill resistance and prevent the car from slipping backwards. In addition to the essentials and operation of the flat road, it is also necessary to pay attention to the close coordination of the operation of the parking brake lever, clutch pedal and accelerator pedal. How:

Step on the clutch pedal and hook up 1st gear; Hold the steering wheel firmly with your left hand, pull the parking brake lever back with your right hand, press the accelerator pedal with your right foot, keep your eyes on the front, and slowly lift the clutch pedal at the same time. When the clutch begins to make contact, the engine is strained, and the car wants to start driving, relax the parking brake lever, slowly lift the clutch pedal, and continue to press the accelerator pedal to start immediately.

If it is a short gentle slope, you can add or decrease the gears appropriately on the basis of regular driving;

When encountering a long slope, car owners should pay attention to:

1) Reduce the speed of the vehicle before going downhill so that the vehicle enters the downhill at a slow speed.

2) Shift into the appropriate gear before going downhill, generally you should choose the second or third gear. It is strictly forbidden to change gears after entering the downhill section.

3) In the downhill section, it is strictly forbidden to coast in neutral gear, and it must be put into the appropriate gear, and the speed of the vehicle sliding must be reduced by using the traction of the engine.

4) Use braking with caution on downhill sections.

Before driving the vehicle downhill, reduce the speed of the vehicle and control the speed of the vehicle to enter the downhill slope. In order to avoid the thermal degradation of the brakes caused by constantly pressing the brakes, the engine braking can be used to control the speed of the vehicle within a range that is judged to be low, that is, to engage the low gear. Models with automatic transmissions can switch to manual mode and keep them in low gear to keep the speed under control.

Precautions when the car goes downhill: 1. Use low-speed gear and brake together: low-speed gear and brake can be used together to avoid brake loss caused by long-term brake operation; When entering a corner, apply the brakes to complete the corner, and after the corner, release the brakes and use the low gear again.

2. Do not slam the steering wheel: the steering wheel used in the downhill section should be light and not slammed on the steering wheel to prevent overturning due to large inertia force, fast speed, and improper use of the steering wheel.

Hello, the driving method when the car goes downhill is: 1. Reduce the speed before going downhill, so that the vehicle enters the downhill at a slow speed; 2. Shift into the second or third gear before going downhill, and it is strictly forbidden to change gears after entering the downhill section; 3. It is strictly forbidden to slide in neutral gear on the downhill section, and the speed of the vehicle should be reduced by using the traction of the engine; 4. Before going downhill, we should test whether the performance of the braking margin is good, and if there is a fault, we should eliminate the simple volt fault and stop it early before going downhill; 5. Do not slam the steering wheel on the downhill section.

When going downhill on a mountain road, put the gear in 1st or 2nd gear and use the engine brake to control the speed. And the automatic transmission has the same way. Although the automatic transmission seems to have only one D gear, in fact, the old automatic transmission will add a "snow gear" or "3 2 1 gear" after the D gear.

The reason is that the snow gear is a low-speed gear, which is equivalent to hanging on 2nd gear, while the 321st gear is to limit the highest gear to 3rd gear, 2nd gear, and 1st gear. Control your speed by selecting. Most people will hang D gear when driving an automatic transmission car downhill, which is a very correct approach, hanging D gear downhill can make the process of driving safer, but from another point of view, this way is also very dangerous.

The precautions are that when the current steep slope is present, the steep slope is quite a test of driving skills and vehicle condition. For this kind of steep slope, if there is a steep hill descent function (mostly seen in off-road models), it is naturally the best, starting the steep hill descent, the vehicle will go downhill at a lower speed, which makes people feel lower.

If you don't have this function, you can only put on a low gear and use the brakes to slow down. Fortunately, in general, the steep slope is not very long, and the low gear + braking is enough to deal with it.

The starting downhill can be carried out according to the leveling principle, as shown in Figure 3-40. However, the acceleration time before the gear should be appropriately shortened, and the gear at the start can be selected according to the slope. However, it is necessary to pay attention to first release the parking brake lever to make the vehicle start to skid, and then slowly lift the clutch pedal, and then shift gears.

In order to avoid damage to parts due to improper handling, it is generally not recommended to start in high gear.

When going downhill, in order to ensure the safety of driving, you should change the appropriate gear in advance according to the slope, and use the resistance of the engine to control the driving speed. If necessary, apply the brake pedal gently according to the slope to assist braking.

As shown in Figure 3-42, the speed of downhill driving tends to get faster and faster due to gravity. In order to ensure safety, it is necessary to control the speed of the vehicle in advance and change the appropriate gear as needed to avoid the danger caused by excessive speed.

Use the service brake reasonably to control the speed of the vehicle, and try to avoid excessive use of the service brake for a long time. As shown in Figure 3-43, when the service brake is used for too long when going downhill, stop to check whether the brake is normal. If you find that the temperature is too high, you should wait for the friction part to cool down before driving, so as to avoid the brake overheating and causing brake failure, making the speed uncontrollable, and even causing danger.

When driving downhill, it is necessary to pay attention to the readings of the barometer (vehicles with air pressure) at all times, always maintain effective air pressure, and stop immediately if the air pressure is insufficient. When using the service brakes, the brake pedal should not be released frequently and continuously to avoid excessive consumption of the compressed air body.

Especially when driving in plateau areas, due to the different terrain of plateau mountainous areas, when the slope ratio is long, be careful not to press the brake pedal all the time. Don't pedal for a while, and then let go of the pedal, it will be dangerous.

On narrow ramps, the uphill side goes first; If the downhill party has already reached the middle of the hill and the uphill party has not gone uphill, the downhill party should be given the first place; Considering that the vehicle is prone to stalling when going uphill, the traffic safety accident is triggered.

When both uphill and downhill vehicles are at both ends of the ramp at the same time, if the downhill vehicle goes first, it is extremely easy to cause driving danger when encountering a ramp at a fast speed; Even if there is a traffic accident, the problem caused by the traffic accident will be reduced compared to the downhill vehicle.

When both vehicles are in the middle of the ramp at the same time, manual transmission is used.

In terms of vehicle types, it is very easy for uphill vehicles to stop when downhill vehicles are restricted, and it is extremely easy to have dangerous traffic accidents on the slope.

In addition, uphill vehicles need to overcome the drag caused by the ramp, and must press the accelerator hard to make the engine produce more power and traction.

to complete the ramp. On the other hand, if you go downhill, you can apply the brakes if you give way.

Be careful when driving:

When you go out to drive, you will encounter various road conditions, and you should do "safe driving, courtesy three first", that is, first give way, first slow, first stop; Establish a sense of safe traffic, develop the habit of civilized travel, and avoid driving with emotions to avoid unnecessary road traffic accidents.

Vehicles traveling downhill give way to vehicles traveling uphill because they are on a narrow road.

It may be affected by the weather and environment to cause the uphill vehicle to slip and stall when parking uphill, which is easy to have a serious impact on the rear vehicle, and even a larger accident, which is not only easy to cause unnecessary losses, but also more likely to cause traffic jams, which shows how important the observance of traffic rules in daily life has on our lives.

According to the third paragraph of Article 48 of the Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China: on narrow ramps, the uphill side goes first; If the downhill party has already reached the middle of the hill and the uphill party has not gone uphill, the downhill party should be given the first place; Considering that the vehicle is prone to stalling when going uphill, the traffic safety accident is triggered.

1. Uphill vehicles and downhill vehicles are basically located at the two ends of the ramp, if the downhill car goes first, the ramp driving speed is faster, which is easy to cause driving danger, if the uphill car goes first, even if there is a travel accident, the problem is quite light.

2. When the vehicles on both sides are basically in the middle of the ramp. If the uphill car stops to let the downhill car, for the manual transmission car model, the vehicle is very easy to stall, easy to slip from the slope to cause a travel accident, because the uphill car because of the resistance brought by the ramp, must increase the throttle, so that the engine emits greater kinetic energy and traction, to complete the climbing.

If the downhill car gives way to the uphill car, it will be much easier, and the downhill car can brake in the middle of the way to go downhill easily.

On narrow slopes, the uphill side goes first; However, when the downhill side has reached the halfway point and the uphill side has not gone uphill, the downhill side will go first. -- The traffic regulations stipulate so.

Downhill let uphill, considering that uphill manual transmission is more difficult to start, of course, if it is an automatic transmission, it is also downhill to let uphill.

One day I drove back to the countryside, on the way to turn and go uphill, a tricycle was ready to go downhill, and yelled at me to see a car coming down, and you rushed up, hey, I stopped in a place where the curve and slope were very shaky, I was afraid of slipping back, and the road was narrow.

Subject 4 exam in the mountainous narrow road will car, ask, is under let up, please.

When driving in this situation, does the uphill give way to the downhill, or does the downhill make the downhill go uphill?

Hello. To slope to avoid wave vehicles.

If you want to wave, you will avoid it.

1. Reduce the speed of the vehicle before going downhill so that the vehicle enters the downhill at a slow speed.

2) Shift into the appropriate gear before going downhill, generally you should choose the second or third gear. It is strictly forbidden to change gears after entering the downhill section.

3. It is strictly forbidden to slide in neutral gear on the downhill section, and the appropriate gear must be hung to reduce the speed of the vehicle by using the traction of the engine.

4. Before going downhill, you should test whether the braking performance is good, if there is a fault, you should go downhill after eliminating the fault, and use braking with caution on the downhill section.

5. Do not slam the steering wheel on the downhill section, because the downhill section has a large inertia, fast speed and improper use of the steering wheel is easy to cause overturning.

6. The distance from the car in front should be kept at least 50 meters. If the slope is too long and the inertia of the car is very large, the distance between the workshops should be increased appropriately.

7. If it is uphill after going downhill, when approaching the bottom of the slope, you should be ready to rush the slope, release the brake pedal in time, and shift into the high-speed gear in time.

In order to prevent the brake from malfunctioning due to long-term friction, it should be hung in low gear to go downhill.

Be sure to apply the brakes, the engine brake is only a safer point than neutral, but it cannot be used as a brake. Do you calculate an account, how much does it cost to repair a broken brake? How much did you lose in the event of an accident? Don't worry about the brakes.

The vehicle driving downhill mainly depends on the size of the ramp and the length of the slope to judge what countermeasures to use. I don't know if you are a truck or a car, according to what you said, it can be seen that the long ramp and part of the ramp are steeper, so the following measures should be taken: the long ramp is relatively slow, not steep, it is recommended to downshift in 4 gear (5 forward gears of the car), if the vehicle is a little faster, bring some brakes; If the slope is steeper, the 4th gear with brakes cannot control the speed of the car, so you must downshift; Even if the downhill slope can effectively control the speed of the vehicle and does not hurt the car, it is usually used to sit and brake.

When braking on a short steep slope cannot control the speed of the vehicle, you must sit in the lowest gear.

The specific situation is treated on a case-by-case basis, the principle of downhill driving, can not hang neutral, downshift with brake at the same time, must be able to control the speed, sudden situation, can stop. Hope it helps.
