Shenhao: Gold Medal Investor

Yang Bo asked Gao Si to park the car in the parking lot at the door and took everyone into a test car.

This test car has four wheels and drags a simple flatbed with 4 sets of seats installed on it, which can accommodate 8 passengers. What is strange is that this test car does not see any steering wheel or gear handle at all.

Such control devices can only be seated and cannot be controlled after getting in the car.

Yang Bo took out his mobile phone from his pocket and fiddled with the software on it.

The car chassis immediately made a buzzing sound and then started to move.

Zhao Mengge was startled, then smiled and said: "I don't think this is a car, but a roller coaster."

Yang Bo turned around and explained with a smile: "It's really not a car, it's just a big toy at most." As he said that, the car chassis carrying 5 people began to accelerate and started driving on the road.

The car does not move smoothly. Every time it travels for a while, it will make a snake-like movement on the road. It is the first time for Gao Si and the three of them to ride on the car. When the car makes a snake-like movement, it is really scary.

Shan Changming explained: "It doesn't matter, it is avoiding obstacles on the road."

Gao Si sat in the front row, and after listening to Shan Changming's words, he looked forward. Although the road was not wide, he did not find any obstacles blocking the road.

Ye Peng also felt strange and asked: "Where are the obstacles? Are they virtual on the navigation path?"

Shan Changming said: "It's not virtual. It's just a roadblock set up on the road. Lao Yang, please stop and let everyone take a look."

The vehicle slowed down and everyone got out of their seats.

Shan Changming walked forward for a short distance, then squatted down, pointed at the road and called everyone over.

Gao Si also squatted down and saw a very thin metal wire standing where Shan Changming was pointing. The metal wire was about 50 centimeters high, 1 millimeter thick, and the color was similar to asphalt pavement.

Gray and black, it is extremely difficult to distinguish with the naked eye.

Since the metal wire is soft, there is no safety risk even if the vehicle hits the metal wire.

Ye Peng saw the metal wire and felt very curious. He turned around and returned to the car chassis to see what equipment on the car chassis was detecting the metal wire.

Gao Si also asked curiously: "Is this based on laser radar detection?"

Shan Changming said: "That's right. Lidar. This is a weakness of lidar. There have been cases where a car guided by lidar hit a wire before."

Zhao Mengge reached out and touched the metal wire standing on the ground and said: "It can detect such a thin thing, so if a fly flies on the road, does your car also need to hide?"

Shan Changming smiled and said: "This is the lidar sensing decision-making I just mentioned. Flies can indeed be detected, but after detection, deciding whether to avoid it is the real difficulty."

"Then have you overcome the difficulties?" Gao Si asked.

"Actually, it's not a complete victory. If it's a taut wire, you should definitely stop or avoid it, but if it's a piece of grass, there's no need to hide."

Zhao Mengge said: "There must be no grass on the road."

"Yes, of course there is no such problem on regular roads. However, our requirement is that as long as the human eye can deal with the problem, autonomous driving must be able to deal with it. Otherwise, autonomous driving will never be able to take off."

Everyone got in the car again. Yang Bo clicked on his phone to start the car.

Gao Si asked: "Why don't you have a steering wheel in your car? Are you ready to aim for level 5 autonomous driving? Is this goal set too far?"

Shan Changming replied: "We definitely cannot directly aim at level 5 autonomous driving. In that case, we will all become martyrs before the car is even built."

"Why is that?" Gao Si was curious.

"The reason why manual control is not installed is that our four-wheel steering system is not compatible with the current steering wheel. The four-wheel steering system used in this car can support a U-turn on the spot. Lao Yang, please demonstrate it."

Yang Bo operated his mobile phone and the car slowly stopped, then turned 360° on the spot and then drove forward again.

"If a steering wheel is installed, the four-wheel steering system will not be able to perform as well as it is today. At most, the car can become a little more flexible than it is now, because the steering wheel cannot convey instructions such as turning around on the spot." Shan Changming said.

Gao Si listened and was silent.

After a while, Gao Si said: "This four-wheel steering system is indeed a bit too advanced. It's a bit troublesome. It's hard to say whether this car will pass the new car declaration once it's finished."

Yang Bo explained: "Four-wheel steering is not a brand new thing. Many high-end models are equipped with similar systems. However, the structure of our four-wheel steering system is different from that on the market."

Gao Si asked: "What's the difference?"

"Their design goal is to reduce the turning radius when driving at low speeds and increase stability when driving at high speeds. Our design goals are different. Our four-wheel steering system can support horizontal movement and rotation in place, which is for the vehicle

Designed for networking and high-density vehicle dispatch.”

Yang Bo's explanation was relatively professional, and everyone was confused and half understood.

Seeing this, Yang Bo said: "I'd better give you a demonstration."

After saying that, he quickly operated on his mobile phone. Soon another similar car came up from behind. The car was coming at a very fast speed. Just when the two cars were about to rear-end, the car they were in suddenly swerved towards them.

It moves to the left, while the car behind it moves to the right, and the two cars pass by each other.

After completing the overtaking, the two cars drove smoothly one after the other. Soon, a third car drove out of the intersection on the left. The car first drove side by side with the vehicle they were riding in, then the vehicle behind them slowed down slightly, and the third car moved simultaneously.

, successfully inserted into the convoy.

After the demonstration, Yang Bo said: "This is the Internet of Vehicles. Cars negotiate with each other and share the right of way. In future urban transportation, traffic lights can be completely eliminated, and vehicle control at intersections can be completed by relying solely on communication between cars.

Scheduling. The traffic rate of the road can be increased by at least 5 times, and there will never be traffic jams."

After listening to Yang Bo's explanation, Gao Si sighed: "The foundation of Optimistic Cars is much stronger than what is seen from the outside. This is completely planning for future transportation in advance. I don't understand why your funds are so tight."

Shan Changming said: "Mr. Gao, you are thinking too much. For companies like us that have entered the D-round of financing, it no longer works to play with concepts. The capital side is eager to push us to the market and take advantage of the new

The trend of energy vehicles has helped them make money. Initially, Mr. Shao’s plan for them was to lay out future cars, but no one has bought this ppt now.”

Zhao Mengge suddenly had an idea and said: "Isn't it just like urban development? When you first draw the pie, you are talking about creating a new cultural center area. When the harvest starts, all the investors will force you to build a community.

Buy a house?”

Shan Changming laughed loudly and said: "Mr. Zhao's metaphor is so appropriate, that's what it is. Hahaha."
