The leader nodded and agreed with Xiang Dahai's words: "Yes, the cars produced by Erqiu are of excellent quality. In the mission on the southern border, there was no one that failed. We still trust Erqiu Factory."
This is called reputation. The reputation passed down on the battlefield is the most important thing. When there was a conflict on the southern border, no one of the cars at the Second Automobile Factory had mechanical failures, so it was highly praised by the army. Second Automobile's off-road vehicle has become the only choice for the army. Until now, a new bid has arrived, and the army still wins the products of Second Automobile Factory!
"Let's go, everyone go to the conference room and listen to the reports of each factory first. You Second Automobile Factory, please report first." The leader said to Xiang Dahai with great enthusiasm.
Xiang Dahai was very excited and wanted to nod, but when he thought of something, he said, "Leader, we cannot be proud. We must be humble and cautious. How can we report first? Let the brothers report first. After all, they are the eldest sons of the country."
"You, is this going to be the finale? What about the representatives of FAW Factory? Do you agree to report first?" the leader asked with a smile.
Generally speaking, good things must be placed behind and used as the finale. Now, the leader has pointed out Xiang Dahai's little thoughts, Xiang Dahai's face is a little red, and Sun Mingyuan, who is beside him, doesn't care: "Okay, let's report first."
After entering the conference room of the base, the leaders sat down. Sun Mingyuan took his laptop to the projector and began to introduce it to everyone. First, when the first slide was played, everyone was stunned.
This slide is an introduction picture. The center is a perspective view of the car that FAW Factory came to bid for. The structure of the long-headed one was criticized just now, but now no one looks at the difference between a long-headed and flat head, but pays attention to the block diagrams pointed by the arrows next to the car.
The upper left corner is the title, which says, "Overland Vehicle Comprehensive Control System". Below, if you count, it should be eight boxes.
"As an off-road vehicle, it must have strong off-road performance. We have studied eight advanced assembly systems for this off-road vehicle. Now, I will introduce to you the leaders in turn. First of all, it is the vehicle control unit, its abbreviation is VCU, which is responsible for coordinating and controlling the entire vehicle. It can be said that it is the brain of the entire vehicle. It needs to observe various road conditions and coordinate the orderly operation of various systems. It is also the core of our vehicle."
Sun Mingyuan said, pointing to the box of instructions. Everyone was staring at each other. Most of their vehicles participating in the bidding were not integrated into the computer control system and all mechanical controls. Who would have thought that FAW Factory is taking such a big step, and the entire vehicle can be controlled by a computer. Isn’t that nonsense?
"Next, let's introduce the power system. The first part is the engine management system, the abbreviation is EMS, which needs to control the power output of the engine. For example, when it is just started, many of our drivers will like to hit the accelerator with big feet. Our management system will refuse to execute such instructions and can only run steadily for more than ten seconds. Of course, it mainly receives the instructions from the VCU, and during the progress, determine the power output based on the instructions issued by the VCU."
"Below the power system is the transmission system. We have specially developed an automatic transmission for this car. It needs to determine the appropriate gear according to the instructions of the VCU. That is to say, with it, even an ordinary novice can choose the right gear on the wild road, perform off-road driving, and switch gears, which is exactly the same as an experienced veteran driver." Sun Mingyuan said.
For the army, cultivating auto soldiers is also a very complicated process. After all, no one will come up and be a veteran. They all start training from novices. Auto soldiers are soldiers, not officers. Therefore, even if they have been volunteer soldiers for a few years, they will still have to be discharged from the army. Once they leave, the novices will come up and continue to start from scratch.

For drivers, simple shifting operations have a great trick. When to choose which gear is not something that ordinary people can play with. Now, with this system, novices can quickly become veterans.
"The power system continues to be transmitted backward through the gearbox. At the back, it is the automatic drive management system, ADM. It can decide whether to lock the differential at any time according to the road conditions to prevent the tire from idling. In this way, once a trap is encountered, it can use the complete tire to break away in time. Many novices lack experience and cannot lock the differential in time. Therefore, after encountering an emergency, they like to step on the accelerator, which eventually leads to the trap getting bigger and bigger. With this system, this situation can be avoided."
For many people, these are like listening to the book of heaven. There are also these things on their cars, but they are all manually operated. I have never heard of automatic operation. It is too magical and incredible. I originally thought that the FAW factory's car used a gantry axle, which is already a high-end thing. Who would have thought that now people don't mention this thing at all. The full set of automatic devices and high-end have already scared everyone.
"Now, let's introduce the walking mechanism. Let's first introduce the previous one. We are using a set of intelligent electro-hydraulic coupled power steering system. Our off-road vehicles often use hydraulic power assist systems. This power assist system depends on the pressure of the oil pump driven by the engine. Therefore, when the engine speed is low, the oil pump pressure is low, the efficiency of the power assist system is low. When driving at high speed, the efficiency of the power assist system is high, which is exactly the opposite of our needs. We need to have a strong steering assist at low speeds.
The steering wheel will be flexible. When driving at high speed, the assist should be reduced so that stability can be ensured. Therefore, we have developed this special power steering system, which can provide the most powerful steering ability at low speeds. Even if it is a little finger of a person, it can pull the steering wheel. At high speeds, it is relatively stable. Its assist strength changes with the speed of the car, and at the same time, it can also help the car return to the right direction at any time. It also responds to the instructions of the VCU and adjusts according to different terrain."
Looking at the dumbfounded people, Sun Mingyuan continued: "Now, I will introduce our electronically controlled and adjustable suspension system."
