What are the meanings of P, R, N, D, S and L in automatic transmission?

The operation of automatic transmission models is not so complicated. Usually, the D file is the best in the world, but there are some places to pay attention to:

1) It is recommended to use S or L gear when going downhill, and use engine brake to assist braking to improve driving safety.

2) When waiting for a red light or stopping for a short time, if the time exceeds 30s, it is recommended to put N-block hand brake, and you can choose whether to keep D-block on the brake within 30s according to your habits;

3) automatic wave can't slide in neutral, and the weakening of braking force will easily lead to rear-end collision, which will not save fuel.

4) flameout step: on the horizontal road, the car enters the parking position, and steps on the brake-tightens the handbrake-pushes the P gear-lightly lifts the foot brake-flameout;

If you park on a ramp or potholed road, you can park in the following ways to prevent the claws of P gear from being pressed by the gear of the gearbox:

Press the brake pedal firmly-put it into N gear-pull the handbrake-release the brake pedal (let the handbrake stop the car)-put it into P gear-turn off the engine.

Automatic cars are often dubbed "stupid cars"!

Why? Because it was invented to make driving easier and make drivers no longer worry. Therefore, the more "stupid" the operation of automatic transmission, the better, especially the newly launched automatic transmission model has been "stupid" to the fourth gear!

1)P position: parking space, used only when parking. When the P position is engaged, the transmission output shaft is locked.

2)N gear: neutral gear, which is equivalent to the neutral gear of a manual transmission car. When it is towed or automatically cleaned, the car can move.

3)R position: reverse position. A gear used only when reversing.

4)D gear: the gear used when the car moves forward. You can automatically shift from 1 to the highest gear (such as 4th gear, 5th gear, 6th gear, 7th gear and 8th gear).

The above is a relatively new gear mode for vehicles. For the old automatic transmission, there are L, 4, 3, 2, 1 and other gears, with the following meanings:

1)L gear: low gear, generally used on slopes.

2) 4th gear: automatic gear shifting only between1~ 4th gear.

3) 3rd gear: only shift gears automatically between1~ 3rd gear.

4) 2nd gear: automatic gear shifting is only between 1 and 2nd gear.

5) 1 gear: fixed at 1 gear without shifting gears.

1)E-position: economic mode, the transmission can run in a high gear as far as possible, which can save fuel.

2)S position: motion mode. After pressing this button, the engine speed will remain high and the upshift will be slow. Try to run in a low gear, and the torque output will remain high.

3)? : Snow mode, used when starting in the snow. It allows the car to start directly in second gear to prevent slipping.

4)OD: overtime. Press this button, the speed of the transmission shaft is greater than the speed of the engine output shaft, which can save fuel when the car cruises at high speed.

5) "+":"Upshift" in manual mode.

6) "-":"Downshift" in manual mode.

It should be noted that when stopping/starting frequently in congested road sections, please try to choose D gear; When it is really necessary to accelerate overtaking, please use the manual mode function to directly select the lower gear with greater torque.

Extended reading

When driving an automatic car, the shift lever should be kept in the D position. The car can automatically shift gears between 1 ~ 4 or 1 ~ 3, and the driver can control the speed by controlling the accelerator pedal.

1) Shift error, idle speed correction. When driving, if you put the gear lever into N gear by mistake, immediately lift the accelerator pedal, and when the engine speed drops to idle speed, put the gear lever into the required gear to continue accelerating. It should be noted that never slide in neutral, otherwise it will easily damage the automatic transmission.

2) The uphill is not big, so you can use D gear. Cars can use D gear when the slope is not big, but it is forbidden to put the gear lever in N gear or D gear when going down a long slope. You need to use the S or L gear, and the speed should be less than 30 km/h. Choosing the L or S gear can achieve a strong engine braking effect and reduce the wear of the service brakes.

3) If conditions permit, use the overdrive gear. The automatic transmission of most new cars is equipped with an overspeed gear (O/D gear). If conditions permit, try to drive too fast. How to use the overdrive gear is as follows: After the engine is started, pull the gear lever from P or N to D, press the overspeed switch on the gear lever at the same time, and then step on the accelerator pedal gradually. When the vehicle speed continues to increase, the gear of the automatic transmission can be automatically upgraded to the second gear, the third gear and the overspeed gear; If you don't press the overspeed switch or press it again, the shift lever can only get the third gear at most when it is in D gear.

4) Step on the accelerator and overtake deeply. When overtaking, just press the accelerator pedal quickly to the end, and other operations and precautions are the same as driving a general car.

5) In rainy and snowy sections, use low gear. When the car is driving on the rainy and muddy road, it is easy to slip in the high-grade D gear, so it is necessary to adopt the low gear, and control the engine speed by using the size of the accelerator pedal to pass at a low speed.

6) Shift mode, select the appropriate one. Most of the electronically controlled automatic transmissions of modern automobiles have two or more shift modes. In the selection of shift modes, the most commonly used shift modes are "economy" and "power". When the "economy" shift mode is selected, the automatic transmission can be upgraded to a higher gear at a lower speed, but the downshift will only occur when the throttle is large or the engine load is high. On the contrary, when the "power" shift mode is selected, the automatic transmission will only be upgraded to a high gear at high speed, and will start to downshift when the throttle is small or the engine load is low.

When an automatic car stops temporarily, it is necessary to choose the correct parking mode according to the length of parking time.

1) short time, braking. Generally, when waiting for the traffic lights, the parking time is short, and when the shift lever is set to D, the service brake is used, because you can start again as soon as you release the brake pedal.

2) the time is a little longer, and d pushes n bits. If the parking time is a little longer, it is best to push the shift lever from D to N, otherwise the oil temperature of automatic transmission will be too high, which will affect its performance and service life, and more attention should be paid to it when traffic jams occur in summer. It is best to tighten the parking brake lever at the same time to avoid accidents caused by the car rushing forward when the brakes are slightly loose.

3) Stop on a steep slope and stop at the P position ... If you stop on a steep slope, tighten the parking brake lever and put the gear lever at the P position.

La la la, here comes the female driver! Nowadays, both at home and abroad, car manufacturers love to mark in English, probably because Chinese characters are too capitalized. Since it is English, we should learn it:

1, p (parking) stands for parking gear.

This is the parking gear, also known as the parking gear, that is, when parking, pull the selector lever to the P position. Make the parking brake of the transmission lock the output shaft and tighten the handbrake, so that the car will not move.

2.r (reverse gear) stands for reverse gear.

This is reverse gear, that is, you should put it in R gear when reversing. Be careful not to change this gear before your car stops, or the gearbox will wear out quickly.

3, n (neutral) stands for neutral.

This letter is neutral and is often used for car starting, trailer and pause, for example, when waiting for a red light.

4.d (drive) stands for forward gear.

This letter is a forward gear, which is often used in normal driving. As long as the shift lever is placed in the D position, the shift can be automatically adjusted when the car is driving.

5.S(Sport) stands for sports equipment.

This is a low gear, which can be used to start on a big slope or on a relatively inclined slope. This will increase fuel consumption.

6.L(Low) stands for low-grade downhill.

This is a low gear, equivalent to "1 gear". When going downhill or down a long slope, the gear here is often used, which can automatically limit the gear of the car to the lowest gear, so that the car can be braked by the engine power when going downhill, so that the driver does not need to step on the brake pad for a long time to cause overheating and danger.

It's a coincidence that the old driver's car just contains P, R, N, D, S and L gears. The car is slippery at present. Get in the car quickly. The old driver will tell you the meaning of these gears, use skills and pay attention to problems. Fasten your seat belt and let's go!

P Parking gear is suitable for long-term parking, because an automatic car cannot be put into gear to prevent the car from slipping like a manual gear. The automatic car is cleverly designed with P gear. When parking, it will be put into P gear and the car will not slip. It should be noted that the handbrake should be tightened before shifting into P gear, which plays the role of auxiliary braking and double protection.

R reverse gear, needless to say, is the same as manual gear. It should be noted that the problem of reversing must pay attention to safety and distinguish between throttle and brake.

N neutral, which means the same as neutral of manual transmission. N gear is suitable for short-term parking, such as waiting for a red light. If you wait for the red light for a short time, just step on the brakes and so on. The hand brake must be tightened before the car is put into N gear to prevent slipping.

D forward gear, automatic gear replaces 1, 2, 3, 4, 5 gears of manual gear. As long as D gear is used to move forward, there is nothing wrong with this.

S gear, automatic gear has more power output than manual gear. In order to make up for the dilemma that the automatic transmission does not accelerate, such an S-gear is designed. Overtaking, uphill and other situations with high power requirements can be used. I tell you, it's great, you can experience it, but the fuel consumption will soar. S file and D file can be switched directly.

L we often say low, just this L. If S gear makes up for the lack of power at medium and high speeds, then L makes up for the lack of power at low speeds. On a big ramp, it can be used in occasions with high power requirements.

If you want to have a 0- 1 with your friends, change to L gear, step on the brake with one foot, step on the accelerator with the other, and release the floor oil with your right foot. Hoo ~ cool! You can directly change from L gear to DS gear, otherwise you need to slow down, just like directly changing from 5 gear to 2 gear, which is definitely uncomfortable.

Automatic cars are still very easy to use, and you need to learn these knowledge seriously. Usually, you must pay more attention to safety when using the car, and the throttle and brake are clearly divided.

I believe that many drivers have been driving for a long time and have not yet understood what the English logo of automatic cars stands for. Although I have specifically inquired about the relevant instructions before, the actual situation basically only uses P, R, N and D when driving. Today, I want to share with you my views on this issue:

Also called parking gear, it means that you can only shift to P gear when the vehicle is completely stopped. It uses a mechanical device to lock the rotating device of the car. It should be noted that if the vehicle is not completely stopped, the damage to the gearbox caused by changing the P gear is considerable. In addition, many automatic cars now have safety devices, and the engine can only be started in P or N gear, or it can only be ignited when the engine is started, thus preventing the vehicle from jumping into other gears when starting.

As the name implies, reverse gear is required when reversing. It is also very important to pay attention to the reverse gear. Only when the vehicle stops can it be put into gear, otherwise it will cause great damage to the gear. Once you have the bad habit of car maintenance, car problems will gradually come out.

N gear refers to neutral gear, which is generally used when starting, trailer or temporary parking. Generally speaking, when we wait for traffic lights or traffic jams for a short time, we often keep the shift lever in the D position, and it is allowed to brake at the same time. However, if the parking time is long, it is best to shift to N gear and tighten the handbrake. Because the gear selection position is in the driving position, the general driving trend of automatic transmission vehicles is weak. Braking for a long time is equivalent to forcibly stopping this trend, which makes the transmission oil temperature rise and the oil easily deteriorate.

As the name implies, the vehicle is moving forward, and the owner only needs to control the throttle. D is the most commonly used driving position. Because the automatic transmission determines the gear according to the size of the accelerator and the speed of the vehicle, if the accelerator pedal is stepped on quickly when starting, the upshift will be late and the acceleration ability will be strong. After reaching a certain speed, quickly release the accelerator pedal and the vehicle will immediately upshift. When accelerating, use D gear to release/step on the accelerator properly, which can make the shift smooth and conform to the vehicle speed, and also has a certain fuel-saving effect.

In the S-gear mode, the delay of gearbox shift timing will first keep the engine at high speed for a period of time, so that the car can drive at low speed and high speed for a long time, and then get greater torque output and acceleration. S gear can sometimes be used as overtaking gear. When using S gear, the engine fuel injection quantity will change, the intensity will increase, the noise will increase, and the fuel consumption will be more touching.

Low-speed gear is the same as D 1, and the gearbox will only work in 1 gear, which is generally used when going up a big slope or down a big slope. When going down a big slope, the engine can be used to cooperate with braking, so that the owner does not need to step on the brakes for a long time to avoid brake failure caused by overheating of the brake pads.

(The article is a bit long. It is recommended that novices read it carefully, and they will certainly gain something. )

This is a good question, because most people still take the driver's license of C 1 and are familiar with manual transmission, but when buying a car, they are more and more inclined to automatic transmission models.

The most intuitive difference between buying an automatic transmission model is that the gear is different from the manual transmission. Here we will talk about the significance of each gear in detail, as well as the matters needing attention in opening the automatic gear.

First, the first is P gear, also called parking gear.

P block only needs to be hung when parking for a long time, and it doesn't need to be hung when parking for a short time such as traffic lights.

The principle is that there is a pawl in the parking system.

This pawl engages with the parking gear during parking and acts as a brake.

After understanding this principle, we can correct the wrong operation of some novice friends when parking, first hang P gear, and then pull the hand brake.

Why is it wrong?

If you put P gear first and then step on the handbrake, the car may move back and forth on the slope. If you don't stop at this time, you will shift into P gear, which will increase the contact force between the chicken feet and the parking gear and seriously damage the parking gear.

So the correct operation steps are:

1. Step on the brake and put on N gear.

2. Pull the handbrake.

3. Loosen the foot brake.

Turn off the fire

5. Put the P gear into the parking gear.

6. Pull out the key.

Then, if your car can only stall in P gear, you can stall in P gear first and then stall, but you must stop the car and then stall in P gear.

Secondly, there is

R gear, which is easy to understand, is reverse gear.

Some novice friends have wide brains. What should I do if I shift the wrong R gear in the process of automatic transmission?

Let's just say that your imagination is too rich. Generally, the gearbox can't be changed to R gear, or your gear can be changed to R gear, but the driving computer will recognize and ignore your reversing instructions.

Third gear and N gear are neutral. In this case, there is no power transmission between the gearbox and the engine.

So at the traffic lights.

1. If the waiting time is expected to exceed 30 seconds, the car will be put into N gear, and brake or hand brake will be applied to wait.

2. If you can start at the green light soon, you can temporarily put the D block on the brake.

Fourth,

D gear can be said to be the most commonly used gear, that is, forward gear, not much to say.

Fifth, S-gear means sports, that is, sports gear. Under the same throttle, this S gear performs downshifting logic, which is generally one gear lower than D gear to output large torque.

What do you mean?

For example, if you step on the accelerator to a certain amount, the corresponding digital gear is 4 in D gear, and then 3 in S gear.

This is to output more power.

Sixth, the last one is the L gear. This gear is a range. The gear of the gearbox is controlled between 1-3, which is generally used when climbing or downhill requires strong power output.

For example:

For example, the long downhill section in the above picture needs to be downhill with low-speed L gear and point brake.

If the D gear is engaged, according to the shifting logic of the gearbox, the downhill speed may be faster and the higher gear may be maintained.

At this time, if you keep stepping on the brakes, it will lead to the thermal attenuation of automobile fragments, the braking performance will be reduced, and the braking failure will be serious.

Therefore, it is the best choice to use L gear and control it within 1-3 gear, and control it with engine gear and foot brake.

All right. One breath popularized the precautions I can think of, automatic driving.

English full name: Parking

Stands for parking gear, parking gear. It is usually used with the hand brake of the vehicle.

English full name: Reverse

Represents the reverse gear of a car. Generally used when reversing, it is not recommended to step on the accelerator when using reverse gear.

English full name: None

Represents the gap between cars. Generally, the foot brake and the hand brake need to be used together.

English full name: Drive

Represents forward gear and drive gear. Generally speaking, D gear is enough for automatic vehicles.

English full name: Sport

Represents the sports gear and overtaking gear of the car. Usually used in overtaking situations.

English full name: Low

Stands for low gear and manual gear. You can shift gears up and down through the shift paddle and shift lever.

I hope the above answers are helpful to your question, and I wish you a safe journey.

My car is automatic and I have been driving for many years. I'd like to share with you the gears and using skills of automatic transmission. P is the parking gear, which is suitable for long-term parking. It is connected with the gearbox through an internal locking mechanism to prevent the car from slipping. R is reverse gear, which is the same as manual reverse gear. N is neutral, just like manual transmission. It is used for short-term parking. D is the forward gear. L is a low-speed forward gear, which is equivalent to the first and second gears of manual transmission. You can use this gear when going uphill to give the car more traction; When you use this gear when going down a big slope, you can use the engine to control the speed and prevent the brakes from burning. It should be noted that the car can be shifted from L gear to D gear and S gear. If the speed is fast, you can't shift to L gear, which will affect the gearbox. S is a sport mode, and the response is more positive when the throttle is engaged, so it can be used when overtaking.

Let's talk about the parking skills of an automatic car first: after the car stops at a predetermined place, you need to push the gear into the N gear and tighten the handbrake, release the foot brake and turn off the fire, and push the P gear to pull out the key. Let's talk about the ignition sequence of some automatic cars first. Insert the key to open the car, put on the brake and put N gear, turn the key to ignite, choose forward or backward, and release the handbrake.

Waiting for a red light is also tricky. If the red light lasts for a short time, step on the brakes. If the red light lasts for a long time, you need to put the gear into N gear and tighten the handbrake. It is not recommended to put it in P gear, because once the car rear-ends, it will cause different degrees of damage to the P gear locking mechanism and gearbox.

I don't think anyone doesn't like cars. Actually there are many kinds of cars. When it comes to classifying cars, there are too many standards for classification. But today I think of a simple classification method, that is, according to manual gear and automatic gear. I wonder if you prefer manual transmission or automatic transmission? In fact, the two have their own advantages. Personally, I prefer automatic transmission, mainly because it is relatively simple and worry-free to drive. There are many letters on the automatic gear, which represent different gears and will only be used at every special time. Can you tell the difference? Let's take a look.

First of all, let's talk about what everyone knows, the letter P, which is familiar to some people. Why? Because in the parking lot, that is, the parking booth, you can see this letter, whether there is a car or not, you can know this booth. Just hang it on this stall when you need to park, but it should be noted that this stall will only be used when you park for a long time. If the parking time is short, you don't need to hang on this stall.
