I ask you to build tractors, but you build rockets?

On November 29, just before December, the first batch of X32115 automotive chips and supporting ternary storage particles/memory rolled off the production line.

To be honest, Huaxin International and Modu Huahong were very confused about these two orders. It's not that they didn't understand. Their chip engineers knew that these chips were ternary when they looked at the pictures.

It is now 2015, 24 years after the demise of the alliance. Those who play with ternary systems are basically amateurs. They use tubes or relays to make simple circuits to shoot videos. There are no practical ternary electrical components at all.

The ternary computer died in its infancy. It is completely incomparable with the mature and powerful binary system, and there is no need to spend huge sums of money on research. Who knows how Xinyuan spent so much effort to develop this thing.

The 28nm process manufactured by Huaxin International has 1.8 billion transistors, composed of 860 million analog effect transistors (what Xinyuan engineers call ternary basic components simulated by diodes), which is obviously extremely complex and mature. the design of.

When conducting yield testing, Huaxin International didn't even know what to do. It could only ask Xinyuan engineers to come to the scene to help, and then it accepted the first batch of chips.

200,000 pieces, with a total price of 590 million yuan. Taping out and testing cost more money. In addition, the total price of supporting components produced by Huahong is also 180 million yuan. The cost of the chip set that can be used in 200,000 vehicles is 770 million yuan. Each car is allocated an average of 3,850 yuan.

Supplemented by other components, installation and testing, the estimated cost is about 9,000 to 10,000 yuan.

With this batch of chips, the 100 XC4 engineering prototypes that have been produced one month in advance finally have usable chips.

According to Xin'an's design, both battery management and intelligent driving will be handled by the X32115, so when there is no chip, you can only test the mechanical performance and crash performance of the sports car, and then wait for the chip.

At the Xin'an Automobile Factory in Shancheng, the first XC4 was installed with a complete X32115 control chipset and then flashed into the XW151 intelligent driving system.

The XW151 intelligent driving system is divided into two parts. The most important battery control and driving parts are brushed into the ternary storage particles on the motherboard. The remaining human-computer interaction, which is also the largest part, is brushed into the traditional solid-state drive connected to the motherboard. .

This is mainly because the price of producing ternary memory particles is too expensive. If the silicon carbide field effect tubes in the system are purely used, the storage density is actually higher than the NAND flash storage density of the solid hard drive, but the cost of using analog field effect tubes is Too high, the price of 1G capacity is as high as 10 yuan, which is two or three times more expensive than the NAND flash memory of the same era.

Therefore, for the secondary human-computer interaction part, Micron's 1T solid-state drive is used. This requires adding a conversion chip to the motherboard, but it is still much cheaper than ternary storage particles.

After the X32115 chip and intelligent driving system are installed, the 2-ton XC4 is considered complete. It was first driven to Southern Motor's closed test road by Xinan engineers.

Although 4G technology has been around for several years at this time, base stations are still far less popular than in later generations. Therefore, the intelligent driving system of this period cannot rely on the Internet and dense base stations to assist. Most of the time, it must be judged based on the vehicle's own sensors and the system requirements. Very high.

In the circular closed road, many Southern Automobile employees also stood here to watch the legendary space sports car.

Last month, I also went on a space trip. The specially launched CS105 space commemorative edition was priced at 350,000 yuan. It actually achieved an excellent result of 41,000 units (including pre-sales) in the first month, which was 1.4 billion. The sales volume has been very high, and it has suddenly created a style that does not belong to domestically produced cars.

After all, although the CS105 can indeed reach a high level in terms of configuration, after all, domestic brands are here, so how can they easily sell at a higher price? To have sales of 40,000 units in the first month is simply a miracle... Tsiolkovsky bless !

Moreover, demand exceeds supply, and many 4S stores have to increase prices to pick up cars. Many people are still waiting for the next batch!

Many other domestic car dealers are jealous and jealous, but this kind of operation is out of print and cannot be reproduced at all. They can only watch Southern Automobile climb all the way up, and at the same time pay more attention to Xinnan Automobile, the son of Xinyuan Automobile.

In 2015, the impression given by new energy vehicles was that they were crudely made, like four-wheeled electric donkeys, with poor safety and performance.

But Xin'an XC4 has a different style when it is released. It is a 2-ton coupe that can accelerate from 0 to 100 kilometers in less than three seconds. It has a dedicated chipset for battery management and intelligent driving systems, and it also promotes "aerospace-grade quality". It is indeed very exciting.

On the test track, the engineer first drove the car and turned on the sports mode to enter the performance state to test the acceleration to 100 kilometers and battery performance.

Xin'an CEO Chen Jun was sitting in the passenger seat, nervously staring at the parameter fluctuations on the laptop screen.

The XC4 drives to the starting line and immediately accelerates to the full throttle when the traffic light turns green. The innate characteristics of the motor allow all 653 kilowatts of power to explode within 0.1 seconds, outputting more than 1,100 Nm of torque.

Chen Jun only felt a strong thrust for an instant, and then the car sped out violently. He could still vaguely feel the tires slipping slightly when starting.

The burst of torque from the motor is so terrifying, it has the advantage of being more advanced in principle than a gasoline vehicle, so much so that the ABS system is difficult to design. Only semi-thermal tires used in special venues can ensure starting grip.

The numbers on the laptop screen jumped from 0 to three digits so fast that they produced afterimages. Fortunately, the test engineer slowed down in time and slowly stopped.

“0 to 100km/h acceleration time: 2.43 seconds, test top speed: 186km/h

Remaining battery: 98.2% (492 kilometers available) Status: Excellent Battery pack maximum temperature: 34 degrees. "

After the 100-kilometer acceleration test, the results were better than originally expected, and the most important thing is that the temperature of the battery pack is not high under the management of XW151, and the output power curve is also very soft, which means that even with sudden high current output, The battery pack is still under the excellent regulation of electronic control without damaging the battery and extending its life.

However, the number of available kilometers is only a reference, based on the most ideal energy-saving state. If you drive it casually, you will get at least a 30% discount.

Then the test engineer started running laps to test the speed, and reached a top speed of 316km/h with the restrictions completely relaxed. The maximum speed in the sports mode open to users is 260km/h. This test did not turn on the intelligent driving system assistance. .

Then the test engineer started the XW151, turned on the advanced assisted driving and set the mode to "Sport" to test the performance of the XW151.

The first is the basic lap. The test engineer ran the lap in a regular but high-speed manner and immediately felt the difference.

After the intervention of XW151, the pedal feedback is more linear and accurate. There is still the same amount of power but the distribution is better. You can clearly feel the power when you step on it a little, and there is no feeling of slowing down and fatigue at the end of the acceleration.

And when switching after turning on lane keeping, you can feel the system helping to slightly correct the steering wheel and throttle, which is smoother than manual. Even novices are not afraid of slipping when cornering and losing grip.
