What do you mean by car gear?

Question 1: What is the RNDP file of the car? P: Parking gear-you need to put it in this gear, and you can't pull out the key until the car stops.

N: neutral

D: Forward gear, which is engaged during normal driving.

reverse gear

Question 2: What is the rnds gear of the car? What's the difference between my 12345 reverse? Automatic gearbox generally has several gears, such as P, R, N, D, 3, 2, 1.

P stands for parking gear, and R stands for reverse gear when parking or waiting for a bus.

N stands for neutral, which means the same as neutral in manual gear. It's for short-term parking!

D stands for forward gear. In this gear, the gearbox will automatically switch to 1 ~ 5 according to the vehicle speed and throttle condition.

Other gears that may appear in automatic transmission vehicles are S gear and L gear, and some gearboxes also have snowflake key OD OFF button.

S means exercise. In this gear, the gearbox can shift gears freely, but the chance of shifting gears is delayed, which keeps the engine at a high speed for a long time and increases the power of the vehicle. Obviously, this will increase fuel consumption.

L stands for low gear, which should be the same as 1 of the new Accord. In this gear, the transmission will remain at 1 without upshifting.

The snowflake button means to start on a wet road. When this button is pressed, the vehicle will start from the second gear instead of 1 gear, so as to reduce the torque output and prevent the vehicle from slipping when starting on wet roads.

The OD OFF key indicates that the highest gear is prohibited. Vehicles with this key often do not have D3, because the fourth gear of the highest gear (4-speed gearbox) has been prohibited by pressing this key, which is equivalent to D3.

-

If it is a manual gear, you need to cooperate with the clutch to shift gears normally. You need to step on the clutch first to shift gears. There seems to be nothing else to explain. After all, under normal circumstances, learning to drive is a manual gear, you know better!

Question 3: What is the meaning of each gear of an automatic car? An ordinary automatic car has six gears, which are P, R, N, D, 2 and L from top to bottom.

Stop the car, stop the car. When not in use, stop the car, and the gear is here. At this time, the wheels are mechanically locked to prevent slipping.

R-forward gear and reverse gear. Use when reversing.

None, neutral. Use this gear when stopping temporarily (such as at a red light). Note that this gear indicates neutral. In order to prevent the vehicle from slipping on the slope, be sure to step on the brakes.

Forward gear, also called drive gear. Needless to say, just use this block when moving forward.

2- low gear, which can be used when starting on a big slope or on a relatively inclined slope. Here, in principle, the gear shift can limit the automatic shift of the car to the low gear (equivalent to the first gear and the second gear of the manual car), so as to ensure that the car can get the maximum forward power.

Low gear. When going downhill or down a long slope, the gear here can automatically limit the gear of the car to the lowest gear (equivalent to the first gear of a manual car), which can make the car brake with engine power when going downhill, without the driver stepping on the brake for a long time, resulting in overheating of the brake pads and danger.

OD-OD gear is an overspeed gear, which is used at high speed to save fuel.

Question 4: What does the gear of an automatic car mean? First of all, automatic gears generally have P, R, N, D, 3, 2, 1. Please remember:

Parking gear

R, reverse

Neutral position

D, driving gear

3,2, 1 means to force the transmission to be limited below a certain gear. For example, 3 means that the transmission is forced to be limited below the third gear.

Well, it's important to remember that. If you know the English words of parking, reversing, driving and neutral, I believe it is easier to remember the symbols of those gears.

Basic driving methods of automatic transmission;

First of all, don't use force when you can't move the gear lever. More than 99% may be that you did something wrong. For example, there is a pull rod under the pole of Opel car, which can be pulled out or pushed into P gear. On the Polo, it's the thumb button, which needs to be pressed. It must be noted that this mechanism is set to prevent misoperation and pushing into R or P gear during driving, which are extremely dangerous actions!

1. When parking, be sure to put on the P gear and pull the handbrake. Parking here means parking for a long time, and people may leave the vehicle.

2. The engine can only be ignited in P gear and N gear. And because of the first point, when restarting after parking, it must be in P gear. Generally, it is impossible to shift to other gears before the engine is ignited.

Correct ignition action:

2. 1. Turn the key to 1 (or 2); Many lights on the dashboard are on. At this time, the computer in the car starts self-checking (equivalent to the startup of PC), and the oil pump starts to work. After a few seconds, the light went out. Depending on the car, some lights will not go out until they are lit.

2.2. Ignition.

2.3. When the idle speed of the engine drops steadily and the pointer of the thermometer starts to move, step on the brake, put on the D gear and release the brake.

2.4. Release the brakes and let's go.

The above ignition process is also applicable to manual transmission cars, except that manual transmission cars must step on the clutch to ignite.

If you think that environmental protection or burning a little gasoline in a hot car is more important than engine life, please skip the hot car step.

Just like computer games, step on the accelerator to accelerate and brake to slow down.

4. If you encounter a red light or other reasons, you need to stop for a short time and step on the brakes to keep the car stationary. Release the brake and start.

5. Stop for a long time, such as waiting for a train to pass at a railway crossing, or knowing that this red light lasts for a long time; See the first point. 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. Especially when the air conditioner works and the engine idle speed is high, it is even more unfavorable. -There seems to be no clear statement on whether to put P or N for long-term parking. I saw a quarrel on Sina for almost two years, especially last summer, and it was so noisy that there was no conclusion at last. Anyway, I touch P gear, and the front wheels and rear wheels are locked together. Besides, parking is designed for P, so there is no harm. )

6. Before shifting from D to P or R, or from R to D (which may be necessary in the garage), please make sure that the car has stopped completely.

7. It's gone.

In short, always put the D file when moving forward; Put the r gear backward; Stop the car and leave in P gear.

Automatic transmission is easy. Otherwise, it is an idiot car.

Don't worry, there are the following points. My experience and practice, or what I read in books and jars, are welcome to further discuss and even pat bricks.

============================================

Intermediate driving method of automatic transmission;

First of all, many automatic gears tend to accelerate with delay. When you step on the accelerator, the engine speed rises quickly, but the acceleration is not fast, usually between half a second and one second. Then, the acceleration rises rapidly, and it seems that the stamina is sufficient. Grasp this flexibly and avoid braking when accelerating in urban areas; Or when overtaking at high speed, there is everything except acceleration.

1. If nothing happens, don't use the N gear. Only when:

1. 1. Turn off the engine while driving, and quickly push the neutral gear to reignite. After lighting the lights, push the D gear to the repair shop.

1.2. When the engine fails to start, other towing ropes or hard connections are needed for traction. Put on the n gear.

1.3. Unless you think it's safer to save some gas money, don't slide the car in the gap like a trolley! ! ! And the life of the transmission. I read an article about DX, he removed the automatic gear, manually ... >; & gt

Question 5: What does the B gear in the automobile gear stand for? Cancel the gearbox, the braking system of the car is basically completed by brake pads, which increases the loss of brake pads, and the frequent use of brake pads leads to safety hazards. In order to solve this problem, the "engine braking" (B) gear is specially designed. When you dial into B gear at a speed of about 50 kilometers per hour, the vehicle will have obvious deceleration feeling without stepping on the brakes; When driving at high speed, the sense of deceleration in block B is not so obvious, and brake assistance is still needed for emergency braking. As the rear brake light does not light up when using the B-block brake, it is recommended not to use this block when driving on the expressway to avoid rear-end collision. When the mountain road goes downhill, block B is the most effective time.

Question 6: What do you mean by all the gears of a car? What is the difference? General situation: the first gear is within 20KM, the second gear 15-30km, the third gear is 30-40km, the fourth gear is 40-60KM, and the fifth gear is over 60KM.

Hope to adopt

Question 7: What does it mean that a car has nine gears?

Question 8: What does P R N D stand for in automobile gear? The following is my collection of articles about automatic driving, but because it is a combination of several articles, I can't tell the source ~ it's just a turn.

Gear position of automatic transmission

Generally speaking, the gears of automatic transmission are divided into P, R, N, D, 2, 1 or L, etc. P (parking): It's for parking. It uses a mechanical device to lock the car.

Turn the parts so that the car can't move. When the car needs to stay in a fixed position for a long time, or before leaving the car after stopping working, you should pull the hand brake and push the joystick to the "P" position. It should be noted that the P gear can only be used when the vehicle comes to a complete stop, otherwise the mechanical part of the automatic transmission will be damaged. In addition, the automatic car is equipped with a neutral start switch, so that the car can only start the engine in the "P" or "N" gear to avoid the car jumping forward suddenly when other gears are started by mistake.

R (reverse gear): reverse gear, used for reversing. Usually, you must press the safety button on the control lever before you can move the control lever to the "R" position. It should be noted that under the condition that the vehicle has not stopped completely, it is absolutely impossible to shift to the "R" gear forcibly, otherwise the transmission will be seriously damaged.

N (neutral): neutral. Put the joystick in the "N" position, and the power between the engine and the transmission has been cut off and separated. If the stay time is short, you can put the shift lever in this position, pull out the hand brake lever, and your right foot can leave the brake pedal to have a rest.

D (drive): forward gear, used for general road driving. Because different countries have different model designs; Therefore, the "D" gear generally includes from 1 gear to high gear or from 2 gear to high gear, and will automatically shift gears due to changes in vehicle speed and load. Put the joystick in the "D" position, and the driver can control the speed just by controlling the accelerator pedal.

Second gear: second gear is a forward gear, but the transmission can only change between 1 gear and second gear, and will not jump to third gear and fourth gear. Put the joystick in the second gear, the car will start from 1 gear, and will automatically shift to the second gear when speeding up. 2nd gear can be used for uphill and downhill. The advantage of this gear range is that when going up or down, the vehicle will stay in the position of/kloc-0 and/or 2nd gear stably, and the transmission will not keep shifting due to load rise or speed imbalance. When going downhill, using the resistance of the engine at low speed as a brake will not make the car drive faster and faster.

1 (first gear Cear): 1 gear is also a forward gear, but the transmission can only work in 1 gear and cannot be shifted to other gears. It works best when used in serious traffic jams and steep slopes. When going uphill or downhill, the torque of the automobile engine can be fully utilized.

A general automatic car has six gears, which are P, R, N, D, 2 and L from top to bottom.

Stop the car, stop the car. When not in use, stop the car, and the gear is here. At this time, the wheels are mechanically locked to prevent slipping.

R-forward gear and reverse gear. Use when reversing.

None, neutral. Use this gear when stopping temporarily (such as at a red light). Note that this gear indicates neutral. In order to prevent the vehicle from slipping on the slope, be sure to step on the brakes.

Forward gear, also called drive gear. Needless to say, just use this block when moving forward.

2- low gear, which can be used when starting on a big slope or on a relatively inclined slope. Here, in principle, the gear shift can limit the automatic shift of the car to the low gear (equivalent to the first gear and the second gear of the manual car), so as to ensure that the car can get the maximum forward power.

Low gear. When going downhill or down a long slope, the gear here can automatically limit the gear of the car to the lowest gear (equivalent to the first gear of a manual car), which can make the car brake with engine power when going downhill, without the driver stepping on the brake for a long time, resulting in overheating of the brake pads and danger.

OD-OD gear is an overspeed gear, which is used at high speed to save fuel. After you know the functions of various gears in automatic wave, you can enjoy driving a car with automatic wave.

Automatic gear use

◇ 1. When the engine is started, the automatic gearbox will also limit the gear, which is adjusted by the manufacturer for safety reasons. In general, the engine can only be started when the shift lever is in the P or N position. If the gear lever is within the driving range, such as D, R, etc. , the engine can't start ... >; & gt

Question 9: What does automatic transmission mean? How to use each file? 1. gear introduction

The so-called automatic gear, as the name implies, means that the driver does not need to manually shift gears, and the vehicle will automatically choose the appropriate gear according to the driving speed and traffic conditions. But why are there so many gears in the automatic transmission? Now briefly introduce the gear and function of automatic transmission.

Take Honda's new Accord as an example ~ The gearbox of the new Accord has several gears, P, R, N, D, 3, 2, 1.

P stands for parking gear, which is used when parking (the engine is turned off and idling for a long time)! ~

R stands for reverse gear. I believe I don't need to explain this! ~

N stands for neutral, which means the same as neutral in manual gear. It's for short-term parking! ~

D stands for forward gear. In this gear, the gearbox will automatically switch to 1 ~ 5 ~ according to the speed and throttle.

3 is also a forward gear. In this gear, the gearbox will automatically switch at 1 ~ 3, and will not shift up to 4 and 5. It can be used as a restricted gear when the traffic is not smooth, which can avoid jumping between the third gear and the fourth gear! ~ (How to avoid it will be introduced below)

2 means second gear. In this gear, the gearbox is in the second gear, which is used as a limit gear when starting on wet roads or driving slowly, to avoid jumping between 1 and the second gear, and between the second gear and the third gear! ~

1 is 1 file. In this gear, the gearbox is in first gear. I don't need to explain this, just look at the situation:)

Other gears that may appear in automatic transmission vehicles include S gear, L gear (such as Honda Fit) and a snowflake button (such as Buick Sail) and OD OFF button on the gearbox.

S means exercise. In this gear, the gearbox can shift gears freely, but the chance of shifting gears is delayed, which keeps the engine at a high speed for a long time and increases the power of the vehicle. Obviously, this will increase fuel consumption.

L stands for low gear, which should be the same as 1 of the new Accord. In this gear, the transmission will remain at 1 without upshifting.

The snowflake button means to start on a wet road. When this button is pressed, the vehicle will start from the second gear instead of 1 gear, so as to reduce the torque output and prevent the vehicle from slipping when starting on wet roads.

The OD OFF key indicates that the highest gear is prohibited. Vehicles with this key often do not have D3, because the fourth gear of the highest gear (4-speed gearbox) has been prohibited by pressing this key, which is equivalent to D3.

It should be noted that in some vehicles, the number 2 above the gearbox does not represent single second gear, but 1 ~ 2 gear (such as Buick). When this gear is used, the gearbox will automatically switch between 1 and 2 without upgrading to a higher gear.

Automatic gears may not have that many gears. Except for P, R and N (these three gears are necessary for automatic transmission), the forward gear is a D gear (such as FAW mazda 6), and the functions of other gears can be realized one by one through manual mode.

2. Driving skills

The biggest advantage of automatic parking is convenience, especially when there is traffic jam, especially when the traffic jam is uphill. At present, automatic transmission is becoming more and more popular. From the perspective of advanced countries, most vehicles have transitioned to automatic transmission, and it is the trend of automobile development that automatic transmission replaces manual transmission as the main vehicle type for daily driving. Many riders are always driving the automatic transmission, so it is certainly possible to drive the automatic transmission, but if you choose the right gear according to the road traffic conditions, then you can greatly reduce the burden of the automatic transmission and reduce the wear and tear of the transmission. In order to make it easier for everyone to understand the truth, the use of automatic transmission limit gear is illustrated with examples in combination with actual driving conditions.

In order to know how to use the limit gear correctly and reasonably, riders should first clearly know the shift timing and shift interval of their vehicle gearbox. The transmission shift timing of each car is different. The engine speed of automatic gear shifting during normal driving is called shift interval, and the shift interval of automatic gear during normal driving is between 2000-2500 rpm. Let me take Honda's new Accord as an example. You can also know the shift timing of your car according to this standard: the gearbox of the new Accord will automatically adjust the shift timing according to the driver's driving situation (the better automatic gearboxes now basically have this function). If you step on the accelerator, the gearbox will automatically delay the shift timing to obtain long-term high-power output. Generally, it will not shift up until 3000 rpm, and it will not shift up until the speed reaches the red line area (if it is fully stepped)>

Question 10: What do you mean by different gears? Gear position is an abstract noun and an abstract concept of the state of each gear set of gearbox. The change of gear refers to changing the working state or working sequence of each gear group in the gearbox to change the power of the engine from low speed to high speed and from low torque to high torque. Different speeds and torques require different gears to convert the power of the engine.

The gear is neither the gear of the gearbox nor the gear lever. It is invisible and intangible. Some people will confuse it with the latter two. I once came across a joke: one of my neighbors bought an old Toyota sports car, and my other neighbor and my classmate boasted to me after making his car, saying that it was too good to have a gear and was awesome. In fact, that car just didn't have a gear lever, but used a steering wheel shift paddle, which almost killed me. . . . . . . . .
