This set of combo punches down.

I'm afraid that I won't have a few years to think about it.

However, autonomous driving can make a name for Longhan Automobile.

The world's first automotive company to achieve autonomous driving.

It's awesome to think about.

Su Han said: "That's right, Shenlong! Are you talking about a hassle to write a smart program? How long will it take? ”

Shenlong said: "It can be written in a minute." However, in order to achieve the desired design effect, it was necessary to redesign the chip and change the body. I can only provide modified drawings, and the specific situation depends on when the engineering prototype can be designed. ”

Su Han said: "Then you are ready to prepare." I will ask the R&D department to design the engineering prototype according to the drawing requirements as soon as possible. ”

"Good boss!"

……

A few days later.

Su Han handed over the new drawings of the control chip provided by Shenlong to Longhan Microelectronics, and asked them to produce the new control chip according to the drawings

The construction drawings were handed over to the R&D department of Longhan Automobile, and they were asked to design the engineering prototype according to the requirements of the drawings.

And, of course, buy some necessary accessories.

It will take at least a month to see the engineering prototype.

……

During the Chinese New Year.

Su Han, Shao Yutong, and Yuan Meixia returned to the county seat for the New Year together.

Su Han and Yuan Meixia have actually not returned to the county seat for a long time.

Mainly because this year is Su Han's first year of marriage, and he has to go back to the county to visit relatives.

Su Han and Shao Yutong planned to turn all their relatives in the county around during the Chinese New Year.

However, the leaders of the county town did not know from there, knowing that Su Han had returned.

I actually came to the door to say hello.

Politely for a long time.

In fact, he wanted Su Han to return to the county to invest.

Of course, Su Han couldn't refuse.

Because since he and Shao Yutong got married.

The old father-in-law, Shao Wenxue, was promoted to the official level by the county.

Of course, Su Han knew that this was the county courting him.

So he agreed to invest in the construction of a 10-billion-level auto parts processing plant in the county.

Anyway, now Longhan automobile industry is very large.

Dropping some accessories casually is enough for employment in the county.

Of course, the county leaders were very happy.

The employment problem that tens of billions of enterprises can solve is not a star.

The father-in-law, Shao Wenxue, suddenly became a big celebrity in the county.

……

years later.

The new engineering prototype was successfully produced.

Compared with the Xianglong S1 engineering prototype, there are almost no changes to the appearance.

Only detection devices have been added to some key components.

The power unit and on-board computer have also been redesigned to add an intelligent core, but most people don't know what this core is for.

Su Han personally came to the new car test center.

Updated the intelligent program generated by Shenlong to the new version of the system.

The next step is testing.

The senior management of Longhan Automobile also stood aside.

Actually, they all felt a little strange. 7

Because the new engineering prototype is almost the same as the Xianglong car.

If Su always wants to come up with a new car.

The shape should also be changed!

Spend money on the same car.

How can a customer be so stupid.

However, Su Han didn't say anything, and everyone didn't dare to ask.

The first is to test the theoretical endurance in the laboratory.

However, before you start the test, you need to turn on the precision power saving mode.

This feature is a new feature of the on-board computer, which can be turned on or off.

After opening.

The on-board computer will alert the driver to adjust his driving status according to the instructions.

After the test starts, the computer will make a sound from time to time to remind the driver to adjust the speed, and the driver also feels very magical.

I didn't expect this computer to be able to talk.

Of course, if the driver does not meet the requirements of the computer, it will repeatedly remind until the other party meets its requirements.

However, after the start of the standard endurance test.

Su Han turned and left.

Because the current standard range of Xianglong cars has reached 950 kilometers.

It usually takes more than 10 hours to test it all.

He didn't have time to wait here.

The standard tests are urban speed (less than 50 km/h) and suburban speed (less than 120 km/h).

The driver has to drive repeatedly until the car runs out of power.

It has been tested in detail.

The cruising range of the engineering prototype with the power-saving mode turned on has reached 1,092 kilometers.

The standard range has increased by 15 percent.

See this result.

Everyone in the R&D team of Longhan Automobile was also a little dumbfounded.

It turns out that this precise power saving mode is not a play on words.

It really saves so much electricity.

Of course, this is only the standard lab endurance.

It does not represent the actual road conditions.

Longhan Automobile's engineering prototype also needs to be tested for outdoor endurance, after all, the real situation is the only criterion for testing product quality.

……

It's winter.

Although it has just passed the Spring Festival, the temperature has risen, and the temperature outside is about minus 10 degrees.

Because lithium iron phosphate batteries do not perform well at low temperatures.

So the R&D team added a heating device to the battery.

Usually it consumes a certain amount of energy.

And the driver also needs to turn on the air conditioner when driving.

In the same case, heating costs more electricity than cooling.

This is also the reason why electric vehicles are more power-hungry in the cold north.

Winter under normal circumstances.

A veteran of new energy vehicles, with accurate control, can control the cruising range at about 660 kilometers.

A novice of new energy vehicles does not know much about new energy vehicles, so the range is about 570 kilometers.

If the road conditions become bad, there are traffic jams or there are frequent climbs, then the range is about 470 kilometers.

But on average, Xianglong cars can reach about 600 kilometers under standard road conditions in winter.

This time, the driver is an old Jianghu.

But this time, he needs to drive the whole way in precision power-saving mode.

The engineering prototype left the research center.

Then go around in circles on the highway outside the capital.

The whole journey of the outer expressway of the capital is 190 kilometers, even if it is 600 kilometers of battery life, it is not so easy to use up the power.

In power saving mode.

The computer constantly reminds the driver to control the speed of the car according to his requirements.

It's just that the driver was surprised!

When his car is close to a certain car.

The computer system will indicate the safe distance of both parties and even the speed of the other party.

This surprised the driver.

Because of driving at high speeds for a long time, many small details cannot be felt at all.

But if you know the speed of the car in front, you can also control the speed in advance, which is very convenient.

And that's not all.

The car in front of you suddenly slows down, and the computer will alert you.

There is a car approaching quickly in the passing lane, and the computer will also alert you.

The driver was also a little dumbfounded.

Does this car have eyes?

What surprised the old driver and the accompanying driver even more.

That's the range of this car.

Originally, in this temperature, even with his driving level, he could only run 650 or 60 kilometers, which was not bad.

But in the end, he actually ran a full 780 kilometers.

You know, it's winter.
