The blind spot of car driving, whether driving or not, should be understood.

Before we begin, I want to tell you something.

Me: the king of bending in the community.

I drove my new calf out yesterday.

I can't believe I was separated by a big brother.

I don't know if you can understand what I mean by "don't"

I move forward normally.

The eldest brother in front suddenly jumped to the left.

If I hadn't reacted quickly

My beloved calf was almost rubbed off by paint.

I really didn't say:

"Eldest brother, what are you worried about in front of my calf?"

"Yadea is amazing!"

"Everyone is not two wheels!"

Because of this, of course.

I ran to the big brother's blind spot.

Brother turned the corner without looking for the car behind him.

What a broad mind.

So today

Let's talk about "blind spots"

of course

It means the blind spot of the car.

The size of two-wheel electric blind spots only depends on

How lazy are you to turn around?

In fact, blind spots are very common.

It was born even before the car.

Bicycles, tricycles, electric cars

There are even blind spots ...

There is also a carriage!

so far

All vehicles have it, too.

Their respective blind spots

generally speaking

The bigger the model, the bigger the blind spot.

So we can see

On buses and trucks.

There is a mirror like this.

I have to say.

This thing looks easy to use

But it is still inevitable.

It still has a certain visual blind spot.

For example, this picture:

Around this van

A * * * standing 123 children.

(Yes, I really counted it)

But sitting in a truck

I can't see any of them!

obviously

This is the blind spot of medium-sized trucks.

That's ridiculous.

If it is a large semi-trailer.

The blind spot will be bigger.

This is a schematic diagram of a truck blind spot.

We can see that in addition to the conventional blind spots before and after.

Among them, the left and right blind areas are the most prominent.

This is also the most deadly.

Because of the inner wheel difference.

Trajectory of front and rear wheels of large trucks when turning.

Inconsistent.

Especially the longer the car body, the more obvious it will be.

So we often see

Accidents in which pedestrians or vehicles are involved in the bottom of cars often occur.

Just because I didn't notice the existence of the blind spot of inner wheel difference.

Let's go back to the blind spot of small family cars.

In fact, the blind spot of family car is more conventional.

Is nothing more than

Front, back, left and right

Four directions

According to my current experience.

There are some cars because the front design is bigger.

It will cause a serious blind spot ahead.

So when I first drove these cars,

It may be in some relatively narrow places such as turning in the basement.

lack confidence

The most dangerous thing is

If before the vehicle is started,

Did not observe in advance whether there were "obstacles" ahead.

Some serious accidents are likely to happen.

There were even casualties.

But now many models

A forward-looking camera is added in front.

At the same time, there are

360 panoramic image

This can effectively reduce the surrounding blind spots.

However, this configuration has only gradually become popular in recent years.

A few years ago, I wanted to reduce blind spots.

Pure?

The intelligence of ordinary people

For example, the left and right blind spots, Otawa rearview mirror.

So about ten years ago,

There is a very popular gadget.

"small round mirror"

This is a convex mirror with high reflectivity.

Because you can see a wide range.

So it is also called wide-angle lens.

Because the original rearview mirror can only see a limited range

When we reverse into the warehouse or overtake.

There will be some blind spots.

For many beginners,

I feel insecure when driving.

So this "plug-in artifact" came into being.

But even though it is small and has a good view.

These undeniable advantages

But its shortcomings are also very fatal.

This convex mirror with great curvature

Will break your existing sense of space

Give you some wrong judgments.

In fact, there may be only vehicles a few meters away.

Small round mirror still has a long way to go.

If you overtake according to the space in the small round mirror

That would be very dangerous.

If the current 360 panoramic image

Used to eliminate the blind area of the vehicle in the static/low speed state.

Then assist the family car in parallel.

A new "good medicine" for changing lanes and overtaking

The principle of this configuration is simple.

Is to use radar to monitor the vehicles in the adjacent lane behind.

If there is a car in your blind spot

There will be a yellow LED light in the rearview mirror on the same side.

Play a warning role.

If you still turn on the lights and change lanes at this time

Will it increase with the risk factor?

Start the buzzer to give an audible and visual alarm.

In the past, this configuration will appear on some luxury models.

But now more and more family cars have started to have this configuration.

It is still very practical

You can pay more attention when buying a car.

Speaking of which,

Basically, we only have one place left to talk.

That's the blind spot of the A-pillar.

This place is the most difficult blind spot in history.

Until now, there is still no better solution.

Here I'm going to start telling stories again.

When I was young,

I just got my driver's license and have been eager to drive.

I remember it was a rainy night.

Because of the origin of dark clouds?

As dark as night

At the corner of a country road.

Suddenly from my A-pillar blind spot

Turn around an old man riding a 28-pole.

Fortunately, he is faster than me.

Jumped out of the car and hid.

I was scared silly.

Drive away.

Uncle, I know you must have scolded me after you got off the bus.

I apologize here.

This shows that the blind spot of A-pillar is really terrible.

I have a long memory since then.

Every time I turn a corner, I will tilt my head to see if it is safe, and then I will go there.

Is there such a serious A-pillar blind spot?

Is it destined to be a bug?

In fact, at the beginning, manufacturers made different efforts.

The most direct way is definitely to make it thinner.

However, as an automobile structure, A-pillar

Important security structure

A-pillar is too thin to ensure safety.

So this is not a good idea.

Another way is

On the basis of improving the strength of A-pillar as much as possible

Open the triangular window on the A-pillar

We have this design on some MPV models.

Will be more common.

And cars.

But because it is related to driving safety.

The triangular window has a limited area.

The optimization degree of blind area is also limited.

Volvo pays attention to safety

Once put forward a radical idea.

The A-pillar is designed as a hollow shape.

And it did appear in the SCC concept car of 200 1.

But it did not appear in the production car in the end.

The following design is more radical.

Because the A-pillar will cause blind spots in the field of vision

Then let it disappear.

Super sports car Koenigsegg Agera? rare

Adopt a whole piece of Daqu front windshield.

The vision of the whole vehicle becomes very good.

But the price of more than 20 million.

It's more than the average person can bear.

The last way

It may be the direction of most car companies now.

That is, through an external camera and a built-in screen.

Realize a-pillar perspective

However, due to technology, display, delay

Wait for questions.

There is no mature technology at present.

Mass production can be realized.

There was once a girl of 14 years old.

Through projection technology

The A-pillar perspective device is realized.

And also won a generous bonus.

I think with the development of 5G technology and technology,

This technology should be available soon.

Relatively great development

Let's wait and see.

Say so much.

In addition to making people aware of blind spots,

I also want you to learn.

What are some places that we can't easily notice?

For example, A-pillar blind area and inner wheel difference blind area.

In short, just remember two sentences.

"Drive more."

"Stay away from big trucks"

Ok, that's all for today.
