When the dual clutch is waiting for a red light, whether to put D gear and apply the brakes or put n

Generally speaking, the D gear is with a drive output, while the neutral gear is unloaded and the engine is idling. When the red light, if you hang D gear, and step on the brakes, it is equivalent to the engine and brake disc in the tug-of-war, temporary braking wins, the result is fuel consumption, the engine and gearbox will heat up, energy turned into heat, pay attention, if your brakes are slightly lax, you may chase the tail of the car in front, hehe. If it is hung in n gear, it means that the engine is idling, and the engine has no power output, but it is rotating itself, which is of course the most economical.

In this analysis, it is recommended to hang back to N gear or P gear when the long red light is long, pull the handbrake, and only a few seconds should not be done again. In fact, waiting for the car in that gear will have no effect on the car itself. Personal original opinions, for reference.

If it is a dry dual-clutch, it is recommended that you can step on the D for a short red light, and if the time is greater than 30 seconds, it is better to push N and pull the handbrake.

This depends on what kind of car you are, many of today's cars are equipped with their own dynamic power cutting off program, that is, there is no power output after stepping on the brake, and the gearbox is not worn.

You can experiment to see if the engine speed under parking D gear is about the same as idle speed, and then adjust to instantaneous fuel consumption to see if it is the same, if it is higher than idle speed, it means that there is power output, no cut-off, more than 20-30 seconds of parking, it is best to put it in neutral position.

When you see a red light and see a red light countdown for more than three seconds, first slowly apply the brakes, then press the brakes and clutch, and wait for the car to stop and then put in one gear and prepare to start.

When you see a red light and the red light countdown is less than three seconds, first slowly press the brakes to reduce the speed of the vehicle, then press the clutch to change to the matching gear, and pass when the light is green, if it is not a green light when you reach the stop line, stop and wait.

Coasting in neutral is an unsafe operation.

Smoothly press the brakes to slow down, then press the clutch again until it stops, and then hang neutral after the car stops.

Regardless of whether it encounters a red light or not, in addition to emergency braking, it is to smoothly step on the brakes to slow down, and then step on the clutch until it stops; You can't put neutral gear in driving, and you can only hang neutral after parking.

1. When coasting in neutral gear, the driving wheel will lose its driving force, and at the same time, the power connection between the engine and the driving wheel will be lost, and the car will slide forward by its own inertia.

Then, if there is an emergency and braking is required, all the braking force will only be provided by the brake, which requires the brake to provide a large braking force in a very short time, but the braking force provided by the braking system is also limited.

Therefore, this will inevitably affect the braking effect, or at least the braking distance will be extended.

2. Coasting with gear, which is commonly referred to as braking with the engine, there is a power connection between the engine and the driving wheels.

Because the running state of the engine has to change to the idle state, the speed has to decrease, and the driving wheels have been trying to keep the engine "synchronized" with it, and finally the result of their "competition" is that the engine speed is not immediately lowered, but gradually decreased, but at the same time, the speed of the driving wheels is also "dragged" by the engine to reduce significantly (engine braking), and there is no "unscrupulous" forward rolling like neutral coasting.

Then, if emergency braking is required in an emergency at this time, the braking effect will be greatly improved under the dual effect of the continuous "containment" of the engine and the vigorous braking of the brake, which is obviously much better than the braking effect of the brake "fighting alone".

1. Stop for a short time.

If there are a few seconds left at the traffic light, you can press the brakes and wait (pull the handbrake if necessary) and stop in 1st or 2nd gear. When the light is about to go green, you can quickly release the handbrake and slowly release the brake to start smoothly.

2. Parking for a long time.

Waiting for the traffic light is relatively long, you can press the brake and clutch to stop, then put the gear into neutral, pull up the handbrake and wait.

Car brake precautions:

1. The brakes tremble.

One situation is that when you brake suddenly, you will feel that the brake pedal will "bounce" like "suddenly, suddenly, suddenly, suddenly, suddenly, this is a normal situation, the reason is that ABS is working and is helping you to brake, which is normal.

The first situation is that there is a problem, because this situation mostly appears on the old body, because the brake disc is worn or unevenly worn, the flatness of the surface of the brake disc has a certain degree of inaccuracy, when this situation occurs, the brake disc should be checked as soon as possible, and it is recommended to choose to use the "disc" or replace the brake disc according to the situation.

2. Brake "off-track".

Brake deviation is also brake deviation, brake deviation phenomenon is the owner when the brake steering wheel has obvious deviation to one side, that is to say, the braking force is large, and the braking force is small. This kind of malfunction mainly occurs in older cars, and once it occurs, it is easy to cause accidents. The main reason for this is that the brake pads are ecteriorated or there is a problem with the brake cylinder, so once this happens, you need to check it immediately.

3. The brake pedal is "soft" and the braking force decreases.

Most experienced drivers should be very aware of what is going on with the "soft" brake pedal, and there are many reasons for this failure: there is a problem with the brake fluid, too little brake fluid, deterioration, air intake, and long-term non-replacement will lead to problems, so the brake fluid needs to be changed regularly. There is oil leakage from the brake cylinder or the pipeline and joint; The stroke of the brake pedal increases for no reason, and the brake pedal does not return.

1. According to the theory, you should step on the brakes first, wait for the speed to drop, gradually downshift, and press the clutch until it stops when it is about to stop. After stopping, put neutral, lift the clutch, and only apply the brakes.

Second, the actual operation is more used, first step on the brakes, and wait for the speed of the vehicle to drop down (this should be based on experience to choose when to hang neutral, generally hung on the gear to step on the brakes, when the speed is lowered, the car will be clucking, before this can be changed to neutral), step on the clutch to hang neutral, continue to step on the brakes until stopped.

After the car stops, if it is a long wait, just step on the brakes (it has been hung back to neutral before), do not step on the clutch for a long time, only step on the brakes, and the clutch plates will be worn; If it's a short wait, a few seconds, you can step on the clutch, hang a first gear, and be ready to start at any time.

To apply the brakes first, do not press the clutch at the same time when braking. When the brakes are stepped on, there are two braking forces on the car, one is the friction brought by the brake pads, and the other is the traction resistance of the engine. If you step on the clutch, there is only the friction of the brake pads, the braking force is reduced, the braking distance increases, and the safety hazard is brought about, and, in the long run, the brake wear is aggravated and the maintenance cost is increased.

During the driving of the vehicle, do not hang neutral gear under any circumstances, and it can only be hung after it is stopped.

2. Hanging neutral gear increases the braking time and braking distance, because the resistance of the engine to the vehicle is lost.

3. Hanging in neutral gear may cause flameout. While this is rare, it is by no means impossible. Once the ignition is stalled while coasting in neutral, the consequences are catastrophic: the steering wheel locks up (even if it is unlocked, it will be extremely heavy if it loses its power direction), the brakes do not move, and the vehicle loses control.

No matter how fast the speed is, the operation should be to first step on the brakes, and then reduce the speed to the point where the car is a little shaky and then press the clutch, and then hang neutral and stop and wait.

Step on the brake first and then step on the clutch, and wait for the car to stop steadily, you can not hang neutral or neutral, and you can't release the brake when you hang neutral, or you can pull up the handbrake.

Brake while stepping on the clutch, and wait for the car to stop before putting in neutral! The rules are like this, and I personally have a habit of putting in neutral and then braking.

Step on the clutch + brake first, and then hang neutral after the car stops.

The car does not go away and then puts it in neutral.

Brake first, the car is about to stop, step on the clutch and hang neutral.

The first case: the speed of the car is fast, brake first and then leave.

Brake pedal braking is equivalent to the braking system and braking system acting at the same time, and the clutch downshift is applied when the engine speed reaches idle speed, which is done to prevent the engine from stalling.

Stepping on the clutch is equivalent to separating the engine from the transmission system, which is equivalent to coasting in neutral gear, and the car decelerates according to inertia, which is very slow, and the purpose of rapid speed reduction cannot be achieved in high-speed driving.

In the second case, the speed of the car is slower, and you can directly press the clutch.

If the speed of the car is slow, such as 1 or 2 gears, you can directly press the clutch to brake.

In the third case, if it is only a slight deceleration, you can only need to collect one oil.

There are other times, such as when we are almost at the intersection of traffic lights, or the brake light in front of us is on, sometimes we can slow down when we turn on the oil, and if we are sure that it is safe to drive forward, we can brake and clutch without stepping on it.

Depending on your speed at the time, you should brake a few times when it is more than 20 yards, and then press the clutch when it is less than 20 yards, so that it will not stall.

When the speed is less than 20 yards, you should press the clutch first, and then brake.

At this time, the speed of the car is generally not fast, if you need to brake sharply, the operation method is: first press the clutch to the end, and at the same time press the brake pedal to stop the car;If you park normally: first press the brake pedal, wait for the speed to drop, feel that the speed is unstable when the clutch pedal is stepped on, so that the car stops, like you can not make semi-linkage, the clutch is not good, if the car stops must use a gear to start, so as not to hurt the car.

<> from a safety point of view, then when waiting for a red light, no matter how many seconds it takes, it is the most standard practice to pull the handbrake while in neutral, there is no one, and no refutation is accepted, the reason is simple - machines are always more reliable than people. Speaking of which, there must be some counter-examples to refute me, such as the Boeing 737 MAX crash that caused a lot of noise not long ago, etc., but you must know that those are all individual cases, I am talking about the results of macro statistics, and the probability of machine error is much lower than that of humans, which is an indisputable fact.

How to operate the automatic transmission in front of the red light is correct, the cat's eye has been a few times before. Which gear we need to switch is closely related to how long we wait. Now the traffic lights in the urban area are basically maintained at about 1 minute, the red light time is still very long, when the owner stops and waits for the red light, the brakes are stepped on for a long time, the right foot appears very stiff, slightly loosen the right foot, move the muscles and bones, and the vehicle may move forward.

Everyone knows that when driving an automatic transmission car, as long as it is in D gear, the vehicle will move forward regardless of whether you step on the accelerator or not.

This means that there is also a power output at idle. Assuming that the red light time is more than twenty or thirty seconds, then my own approach is to pull the handbrake in N gear, if the red light time is only less than 20 seconds, then I generally hang D gear and step on the brakes. Traffic lights without a time display are generally less than 30 seconds.

It is recommended to hang in the n file here. Because when waiting for the traffic light, the car still has the effect of moving forward, and pressing the brake will cause unnecessary damage to the car's gears.

From the point of view of safety, it is necessary to hang the N-gear handbrake, stand in a comfortable angle, step on the brake for a short time, hang N-gear for a long time, and stand in the technical point of view, both operations do not have the problem of hurting the car.

At a red light, you should put on N gear, and if you put on D gear, the vehicle will move forward.

In fact, both of these methods can be used, which will keep the car under control and will not affect everyone's normal driving.

From a safety point of view, the handbrake must be pulled in N gear.

If you think about it from a safety point of view, then when waiting for a red light, no matter how many seconds it takes, it is the most standard practice to pull the handbrake while hanging neutral, there is no one, and no refutation is accepted, the reason is simply that machines are always more reliable than people.

When waiting for the red light, of course, the automatic transmission is to step on the brake and then hang the N gear. How to operate the automatic transmission car correctly when waiting for the red light has become a hot topic at the moment, I believe that many car owners will be thinking about how to use their automatic transmission car when they buy an automatic transmission model, many owners said that stepping on the brake and hanging D gear can also be, but I think it is not good, if you wait for the red light, you hang to the D gear, as long as the car behind you rear-end you, then your automatic transmission will be seriously damaged, thereby increasing their own maintenance costs, If you step on the brakes and hang in N gear, even if the bike behind you rear-end you, it will not cause damage to your gearbox. <>

If it is from a safety point of view, I think it is most appropriate to hang in N gear, the owner waits for the red light No matter how many seconds, it is the most standard practice to hang neutral gear and pull the handbrake at the same time, and do not accept any refutation. The reason is very simple, that is, the machine is always more reliable than humans, because the probability of machine error is much lower than that of humans, and the probability of human error is very large, because it is affected by external factors and personal factors, if you hang in N gear and pull the handbrake, I believe that in addition to the case of external interference, then this car is absolutely safe. <>

From a technical point of view, stepping on the brakes and hanging N gear does not hurt the car, if you are hanging in D gear, it is easy to get on the car, the reason is also very simple, because in the process of parking, if you hang the gear in D gear, the gearbox will run at high speed, which increases the load of the gearbox, and the high-speed operation of the gearbox will make the internal parts generate enough heat, so that some rubber parts will age, which will lead to a shorter service life cycle of the automobile gearbox. <>

Therefore, how to park when the automatic transmission car is waiting for the red light is as I said above, that is, step on the brake and hang N gear and then pull the handbrake, which is the most correct statement, so as to ensure the safety of your own driving, but also to ensure the safety of your car, so it is very important to develop a good habit.
