In the past, why did manual transmission cars need to change gears, and why didn t they use automati

Automatic is much more expensive than manual, in addition to fuel consumption, and there is no driving pleasure at all, just like driving an electric car.

Automatic is more fuel-intensive than manual.

Nowadays, most people choose to buy an automatic transmission when buying a car.

models, but there are also many car owners who do not know how to gear when driving automatic transmission models, in fact, automatic transmission cars need to change gears, but the method of shifting gears is very simple, which can make it easier for them to drive a car on the road. Especially for novice drivers, automatic transmission models will be more suitable and safer to drive. So how do you shift gears in a car with automatic tarding gear?

1. Normal shift of the gear knob automatic transmission model:

When we encounter a handlebar-type automatic transmission model, first we need to know the meaning of each letter on the gear plateP stands for Parking, R stands for Reversing and N stands for N StopNeutral, D for Forward Gear, S for Overtaking, andHand in oneatGearboxMedium plus minus gears。Generally, driving a car will press and hold the gear knob button to push into the forward gear, so that the car can drive normally. But we must not develop a bad habit of "D gear in the world", we must learn to use plus and minus gears to better protect the gearbox and engine, but also play a good role in fuel saving.

Second, the knob automatic transmission model normal shift:

For some high-end models, the car will use the knob gear, and the knob gear will make the car more advanced and the driver will be more convenient to operateHowever, the letters of the knob block represent the same meaning as the letter of the knob。When the owner of the car correspondsWhen driving in different environments, you need to rotate the knob to the corresponding place。There are many car owners who will not pay attention to the rotation error when using the knob gear, which is a very dangerous situation, so we must pay more attention when applying the knob gear.

The widespread use of automatic transmission is of great help to both the automotive industry and car owners, making their cars smarter, making their driving easier, and making their operations simpler. ButWe must also concentrate when driving a car, and we must not take it lightly.

Gear shifts are required. The gears are mostly P gear, N gear, D gear, R gear, empty balance S gear and L gear, in addition to D gear and S gear two gears to switch at will, other gears need to step on the brake bucket to do the car first, and then change gears.

The car with automatic reading gear does not need to change gears, because during driving, it will automatically switch gears according to your speed and speed, and there is no need to manually switch between them.

I think of course you need to change gears, and you need to push P to D at the start to drive.

In the automotive world, there are many brands of cars, and in many cars, it is nothing more than manual gears and automatic transmission models. Choose or based on your own driving habits, prefer the manual gear, because when the manual block changes, it feels really cool. If there's a racing speed, there's a habitual feeling when you have the manual gear and then change the automatic block, but if you drive the automatic block it's used to change the power stop, it's very uncomfortable and there's a lot to be aware of.

Many people know that when moving a car manually, you need to pedal, then hang the gears in the corresponding position, and the clutch is automatically stopped.

There is only one brake and throttle valve under the foot.

As long as the gear moves forward or back, step on the accelerator, so there are a lot of people who use it to automatically stop the car when they start the dynamic gear, they don't just pedal. When it starts, the car does not move, and the direct suspension does not cause damage to the car. If you need to change shuttles while traveling, there is a possibility that the gear can be scrapped.

Again, when the brakes are applied, the person who turns on the car is in the brakes. In general, it is the first time the brakes are sent, and the person who opens the car steps directly on the brakes. Here, it should be focused on.

Some people have a bullet train. When they pedal the brakes, they occasionally don't step on the clutch, but this is a few, generally stepping on the brakes on the first step, because this will allow the car to stop in the shortest possible time, if you don't step on the clutch in the shortest amount of time, the braking distance of the car.

Relatively long. <>

There are also manual vehicles that need to change the speed of the vehicle, the automatic gear does not need to change, just step on the accelerator, it will change automatically, so some people automatically stop the car habit at the beginning of them, usually when the suspension stops, that one will not hang other gears, directly to the throttle, knowing that the driving time is very long, and the engine is also damaged.

Shaw note: The advent of self-stop cars is indeed convenient for many novice drivers. There is only one throttle and brake, which hangs directly to the step, but if you want to change the dynamic gear, you should try it, after all, all the operating procedures of the manual gear are more complicated than after the automatic block.

If you have never driven manual gears and only automatic blocks, then I advise you not to drive, especially in that kind of vehicle traffic to a large extent, once your garter belt can't keep up, there may be some unnecessary traffic accidents.

You can also get used to it, because the automatic transmission is easier to operate than the manual transmission, although it may be difficult to adapt to the automatic transmission at first, but you can get used to it after a long time.

The habit of driving the same, at the beginning of waiting for the traffic light and always want to change gears, after a long time, it will not be like this, except for changing gears, there will be no big difference in driving.

I'm used to it, but I'm used to driving automatic transmission models, and it's a little strange to drive a manual transmission.

The automatic transmission car can not change gears while driving, because the automatic transmission car has only four gears, a reverse gear, a driving gear, a parking gear, and a neutral gear, and only the driving gear is used during driving, and several other gears can not be forward, so it is said that it cannot be shifted, and it is dangerous to change other gears halfway.

The automatic transmission car can change the gear by itself while driving, avoiding the trouble of manual operation of the shift, and will judge the shift according to the speed of the vehicle, if you encounter the situation that the automatic transmission model can not change the gear while driving, it may be that the transmission is faulty, and you can go to the 4S shop for maintenance and detection.

Because changing gears while driving will reduce the oil pressure of the transmission, affecting the lubrication and heat dissipation of the transmission, and it will definitely damage the transmission in the long run.

Because sometimes the gear cannot be hung during driving, the clutch may be worn, and it will also cause accidents, which is basic common sense.

Automatic. The model generally does not need to change gears during normal driving, because of D gear.

It is automatically shifted according to the rpm, and some special road conditions require a gear shift, but it is not done in D mode.

1. When the vehicle is uphill and the slope is large.

Because the D-gear shift speed is low, mostly around 2000 rpm, there will be a lack of power for large slope road conditions, at this time, we can use manual or S gear mode to lock the first or second gear to achieve high-torque climbing and prevent rolling. In this case, you can change gears without stopping, switch directly from D gear to manual or S gear mode, and then use the gear lever -number to switch gears, and change back to D gear at the end of the uphill slope to drive normally.

2. When it is necessary to speed up and overtake.

Because of the focus on ride smoothness and fuel economy, the D gear will lag when it is necessary to accelerate sharply to overtake, so we need to use manual or S mode to achieve stronger power response.

Switch to manual or S gear in advance, here you need to note: after switching, the gear will be maintained in the previous D gear state, such as the speed of 60 kilometers may be in 4th gear, after the switch is still 4th gear, if you need to accelerate sharply, press the " " number to lower the first gear and step on the accelerator to speed up, and then change back to D gear after overtaking and returning to the normal lane. You can also switch to S gear and simply step on the accelerator to accelerate, because the S gear itself is a high-speed upshift, and the acceleration will be much faster than the D gear.

3. When you need to control the speed of the vehicle when you are downhill.

If the vehicle is natively equipped with a hill descent, this can be ignored. For cars that don't have this feature, going downhill in D gear will be accelerated by gravity.

And faster and faster, at this time, manually or S gear press the "-" number to lock a lower gear, such as third gear or second gear, etc., and use the engine to pull the effect to achieve the purpose of reducing speed.

4. When you want to experience driving in manual transmission.

Automatic transmissions are equipped with manual or S gear mode, which can realize manual transmission operation, and some models need to shift the gear lever to cut into the manual mode, and then use the gear lever to fluctuate back and forth to achieve addition and decrease of gear; Some have an S gear, and the gear is added or subtracted by the "-" sign on the head of the gear lever.

But the automatic transmission model is not forever without shifting, the automatic transmission is automatically adjusted according to the change of speed and throttle, and there are many special situations on the road, the driving computer of the automatic transmission can not distinguish, so now the automatic transmission car generally has snow mode, sports mode and manual assistance mode to help the car complete the driving of special road conditions. In addition, the general automatic transmission models also have 3 gears, 2 gears and even gears, etc., these gears are generally in the uphill section, which plays a role in restricting the car from increasing gears. If you use these features regularly in your automatic car, you have mobilized every cell in the car; If you're not using these features, you don't know enough about cars.

Reasonable use of neutral gear can also achieve the purpose of fuel saving, such as when waiting for the red light, push to neutral (n), pull the hand brake, will cut off the power output of the engine, at this time than in the "d" gear, stepping on the brake will definitely save fuel. Remember, don't coast in neutral while driving, as mentioned earlier, this won't save fuel and will increase wear and tear on the gearbox.

You don't need to change gears, the accelerator is stepped on heavily and automatically shifts, you just step on the accelerator, step on the brakes if there is a situation in front, and you can shift to N gear when waiting for a long time at the traffic light.

It is necessary to change gears, to understand the needs of automatic transmission car shifting, according to the shift situation in this regard, it is necessary to know the lack of knowledge and change it. You should understand the needs of shifting, pay attention to the requirements of shifting sharply, and you can shift gears according to the observed situation.

It is necessary to change gears, understand the way of shifting, pay attention to the requirements of shifting, and shift gears through the correct operation method.

I think of course you need to change, for example, when you start to switch to D gear, and when you stop parking, you have to press the brakes to switch to P gear.

<> "Self-tease gear car generally does not need to change gears in the normal process of driving, but if the driver wants to speed up and overtake, the D gear response is relatively sluggish at this time, and the gear can be hung to the S gear can provide more powerful power for the vehicle, so as to achieve rapid overtaking.

In addition, when the automatic transmission car is downhill and uphill, the D gear cannot meet the demand, and it also needs to be completed manually or by making the wheel sell in the S gear mode. When the vehicle is driving the car, if there is a traffic jam or driving on a relatively slow road section, it can be attached to the position of L gear.

When the automatic transmission vehicle is driving on the normal road, it only needs to control the accelerator and brake, and these two pedals can be satisfied. The automatic transmission of the automatic transmission will automatically calculate the appropriate gear according to the specific parameters such as the speed and rotational speed, as well as the opening of the accelerator pedal. The driver does not need to manually shift gears when driving this vehicle, so it is easier to drive and more comfortable while driving an automatic transmission.

The manual transmission cannot be changed to an automatic transmission.

Under normal circumstances, it is not possible, and the manual modification may be suspected of illegal modification, because the illegal modification includes the modification of the appearance, power unit, transmission device, and brake system of the motor vehicle that is not allowed by national laws and regulations and allowed by the manufacturer to exceed the load level and function of the original design plan, whether it is replaced with an automatic transmission or an automatic clutch is installed, it is all a modification of the driving force and transmission system of the car, and it is not approved by the relevant departments to belong to the illegal modification of Zhengjia.

If the same car series has an automatic transmission, it is easier to change, and it cannot be inspected annually after changing to an automatic transmission, and the automatic transmission (changed to a continuously variable transmission) consumes more fuel than the manual transmission, and the driving force is significantly reduced. The clutch of the manual and automatic braking system is a key component of the car, which involves key parts such as gear and speed regulation, and it is easy to leave safety risks to the car once the actual operation is unreasonable.
