For automatic transmission cars, what does the English letter represent?

p stands for parking gear, which is used when parking, and the gears of the transmission system are engaged, and the vehicle does not slide;

R stands for reverse gear, I don't believe I need to explain this, right?!

n stands for neutral, and the neutral of manual gear means a meaning, which is used for starting and stopping for a short time!

d represents forward gear, and the gearbox will automatically switch gears according to speed and throttle in this gear;

S indicates Sport mode, in which the gearbox can shift freely, but the shift will be delayed, allowing the engine to remain at high revs for a longer period of time, which will increase the power of the vehicle, and of course, this will also cause an increase in fuel consumption.

How to drive the car in automatic gear: get into the car and put the gear to neutral N, start the car, press the brake pedal (foot brake) with the right foot, push the gear to D gear, release the brake pedal with the right foot, and the car will move forward, and then put the right foot on the accelerator pedal to drive normally.

When it comes to driving, automatic cars are indeed a lot more convenient than manual ones. One less clutch is like freeing one foot. However, at the beginning of the design of the automatic transmission car, various factors were also taken into account, so several gears were also designed, and each gear corresponded to the corresponding function.

Today, let's talk about the automatic transmission car: P, R, N, D, S, L, M, what do these 7 gears mean? The veteran driver may be able to tell you the answer, and the novice knows that he will not suffer.

The first: P file. This is the gear used when parking for a long time.

Generally, it is necessary to use it with n gears. When the P gear is engaged, the gearbox and the like are directly locked. This also prevents slipping.

The second: r. This is in reverse gear.

This gear is the same for both manual and automatic cars. When reversing, the gear to be used is generally to wait for the car to stop and then put it into this gear. The third:

n gears. This is the famous gap. It is often misused, and many car owners mistakenly think that when using this gear downhill, it will save fuel.

This is not right. In fact, it is easier to use when parking for a short time. Then it is to cooperate with P file and park for a long time.

Fourth: D file. This is the most commonly used forward gear.

This gear is often used by car owners regardless of road conditions, whether it is uphill or downhill, it is unscientific. Fifth: S file.

This is a sporty setting. When in this gear, the engine can provide more powerful power, and when overtaking, it can be more fuel-efficient. It is much more fuel-efficient than hanging D gear and slamming on the accelerator.

And it's a lot faster. Sixth: L file.

This is a low gear. When going downhill or uphill, hooking this gear can make better use of the engine's power to brake or save fuel. When going downhill, you can turn down the engine speed and use the engine to brake instead of slamming on the brakes all the time.

Seventh: M file. This is a manual transmission in the manual automatic model.

When this gear is engaged, it can be adjusted to drive in manual transmission.

Very detailed explanation upstairs. In the tank!

The letters of the automatic transmission are meant as follows:

1. P - parking gear. When the engine is running, the automatic transmission can easily travel as long as the gear lever is in the driving position. When parking, the gear selector lever must be pulled into the P position, so that the output shaft is locked by the parking brake device inside the transmission, and the hand brake is tightened to prevent movement.

2. R - reverse gear. The R position is a reverse gear, so keep in mind that automatic transmissions are not semi-linked like manual transmissions, so pay special attention to the control of the accelerator pedal when reversing.

3. N - neutral. The n-position is equivalent to neutral gear and can be used when starting or when towing. When waiting for a signal or in a traffic jam, the gear selector is often held in the D position and the brake is applied at the same time.

This is allowed if the time is short, but it is best to switch into the n position and tighten the hand brake if the stop time is long.

4. D - forward gear. When driving normally, the gear selector lever is placed in the D position, and it can automatically shift between 1 4th gear (or 3rd gear). The D position is the most commonly used driving position.

What needs to be mastered is that since the automatic transmission determines the gear according to the size of the throttle and the speed of the vehicle, the speed of the vehicle when changing gears is also different due to the different operation methods of the accelerator pedal.

5. S, L - low gear. The automatic transmission is in the low-gear range in the S or L position and can be used on ramps, etc. When going downhill, switching to the S position or L position can make full use of the engine braking and avoid overheating the wheel brakes of the car and the brakes, resulting in a decrease in braking efficiency.

However, when changing from the D position to the S or L position, the speed of the vehicle should not be higher than the corresponding upshift speed, otherwise the engine will vibrate strongly, causing the oil temperature of the transmission to rise sharply, and even damage the transmission.

That is, parking, P gear is a parking gear that is often used.

That is, reverse reverse, which should be hung in R gear when reversing.

That is, neutral. When staying in Orange for a short time, such as waiting for a red light, you can put the gear into N gear.

This represents the forward gear, which is used for normal driving, as long as the gear selector lever is placed in the D gear position, the car can automatically adjust the gear when driving.

It represents a low-speed gear, which is equivalent to 2nd gear, and is often used when going uphill and downhill.

It's the sport mode, and some models have an S gear configuration.

The P on the gear of an automatic car stands for Parking, R for Reverse, N for Neutral, and D for Forward. Here's an introduction to these gears:

1. P gear. That is, parking gear, parking gear, the use of the gearbox mechanical device to lock the rotating part of the car, must be in the case of the vehicle completely stopped before the use of P gear, in addition to the car when the gear must also be in the P gear.

2. R gear. When reversing, as the name suggests, when reversing to hang this gear, it should be noted that when the vehicle is not completely stopped, do not force the R gear, which will cause the transmission to wear.

3. N gear. That is, neutral gear, generally when stopping for a short time, it will hang neutral, at this time the right foot can leave the brake pedal to rest, but if it is up and down the slope, you also need to step on the brakes, otherwise it will slip, unless you pull the handbrake electronic brake, etc.

4. D gear. Forward gear, drive gear, when hooked into D gear, the driver only needs to control the accelerator pedal to control the speed, and the transmission will automatically determine the gear according to the size of the throttle and the speed of the vehicle, so there is no need to manually change gears.

r is reversed, this one is reversed. n Neutral, this is Neutral. This is D gear, and this is Forward gear. It's p parking, it's parking. It's a low gear, it's a low gear. It's motion, it's sport mode. These are the letters on the automatic transmission car.

Automatic transmission cars are equipped with automatic transmissions. There are three types of automatic transmissions that we often see, which are dual-clutch transmission, AT transmission, and CVT transmission.

Dual-clutch transmission is currently a hot automatic transmission, which is a product developed on the basis of manual transmission.

The structure of a dual-clutch transmission is similar to that of a manual transmission. This gearbox just has one more clutch and one more shift control mechanism than the manual gearbox.

One clutch in the dual-clutch transmission is used to control odd-numbered gears, and the other is used to close the stop to control even-numbered gears.

The dual-clutch gearbox has a fast shift speed and high transmission efficiency. This gearbox is more suitable for performance cars and supercars.

The AT gearbox is a torque converter gearbox, and the car is connected to the engine through the torque converter. The inside of the AT gearbox is full of planetary gears. This gearbox technology is mature and widely used.

The CVT gearbox is an automatic transmission with a simple structure. Inside the gearbox there are only two helical gears and a chain of steel plates.

The CVT has a smoother shift.
