What's the use of L, S and M gears in automatic transmission?

What's the use of L, S and M gears in automatic transmission?

At first, I bought automatic gear for convenience, simplicity and beauty. P, R, N, D, parking in P gear, reversing in R gear, and neutral N is not very easy to use. Just put a D in the front and the car will move.

Nowadays, cars are becoming more and more complicated, especially the integration of hands and feet. What are L, M and S files? Are these things useful? How to use it? Will it break if it doesn't work well?

What's the L-block on an automatic car for?

First of all, this l block is the most chaotic. It is the first letter of the English word Low, which means low grade.

In this state, its gear position will be limited. For example, we are a six-speed gearbox. If we press L in third gear, its gearbox will only switch between first gear, second gear and third gear.

Some cars are set for you, for example, there are only first and second gears, so what is this thing for?

Climbing with load and driving in mud increase traction.

In other words, when climbing a hill with load, you need a lot of traction or torque, so you need a lot of strength.

It's our ordinary car. For example, from 2000 to 4000, there will always be an upshift, right? If this L gear is hung over there, it won't be upshifted. It is more important to continue climbing after switching from 5000 to 6000.

By increasing traction, this unpaved muddy land may be opened, but it may not. Too much force may slip, which is at least an option.

Long downhill control speed

In addition to the two functions just mentioned, this long downhill can also use L gear. When we go downhill, even if we don't step on the accelerator, the car will drive faster and faster, especially on the mountain. Don't be scared to death.

It's uncomfortable to step on the brakes. If you keep stepping on the brakes there, the brakes may fail, overheat and drop. Putting an L gear can solve this problem well, and the speed can be effectively controlled through the gear.

L gear is still more practical. I think the most common thing is to put L gear when going downhill. After all, the load of pulling goods is hard to touch. It doesn't work well in mud, because the traction is too strong to slide.

What's the S-block on an automatic car for?

Then this S block is the English word Sport, which is basically known by every friend, but basically every friend doesn't use it, for fear of driving the car bad.

Completely release engine power.

In fact, the principle is very simple. At the beginning, in order to save fuel or be comfortable, our car was upgraded after driving for two or three thousand revolutions.

What about after the S file? It may take four or five thousand revolutions to upshift, and the power of this engine will be fully released, and the fuel consumption will of course be higher.

Shorten overtaking time by using S gear in high-speed overtaking.

What is this thing for? It is very good to use this when driving at high speed. The shorter the overtaking time, the higher the safety factor.

If there is an S gear to overtake and change lanes quickly, it will actually be helpful to our safety and it will be very cool to drive.

Occasionally used in the city can clean up a little carbon deposit.

Then the city occasionally uses S gear, and the throttle can play a role in removing carbon deposits.

It's just not worthwhile. It is better to add a bottle of fuel treasure to the cooked oil, but at least we know that it has such an effect or a good side effect.

What's the M-block on an automatic car for?

The most puzzling thing is the m block. Some cars have a plus sign and a minus sign on the edge of this D block. This is the legendary unarmed fusion. Then why?

Manual adjustment lifting device

That is to say, whether it is an upshift or a downshift, we can adjust it freely by pressing this button or moving the gear lever left and right or up and down.

Then many friends are worried about whether I will pull the car down because of the high speed, or upshift too fast and so on.

It's called automatic manual gearbox, which is completely different from our manual gearbox. First of all, it doesn't need to step on the clutch, and then it won't stall. This is a big difference between automatic transmission and manual transmission.

Shift operation can only be carried out within the range of safety parameters.

Then, the upshift and downshift we can set will actually be implemented within its safety parameters.

For example, my car has been driving until 120 km/h, and manual downshifting to first gear will not be implemented, otherwise the engine will be pulled off or the gear will fail, right?

I was reversing at a low speed and only drove 20 kilometers per hour. It was unrealistic for me to move up to ninth gear.

Don't worry about car injuries, improve driving pleasure.

So in this mode, you hardly have to worry about damaging the car or stalling it because of your own operation. More often, it is to satisfy your driving pleasure.

At this time, I will raise one liter, and at this time, I will raise another liter. I want you to lift the accelerator after I step on it, mainly for this purpose.

The CVT gearbox feels more direct to use.

So just now, these are mainly aimed AT dual-clutch gearbox and traditional AT gearbox, and CVT gearbox may be slightly different. Originally, it was a continuously variable transmission, but after you put it in M or S, it will simulate several ordinary AT gears.

For example, simulate the sixth gear, from the original sliding slide to stepping on the stairs, so that the power will be more direct and the driving pleasure will be more.

What gears are L, S and M on the gearbox? Let me give you a brief introduction today. You can try it yourself. This car won't break down. It's a pity that the function you bought is not used.
