Chapter 38 (1/2)

Thanks to the promotion of old customers and pricing strategy, the iron ox x with a price of 35000 yuan sold 20000 units in a few months, although it did not make much profit as agricultural equipment.

At this price, the automatic cultivated land function is worth it. Most people won't let the equipment idle after the sowing season.

Customers are very enthusiastic about various other uses. Tieniu x can record the GPS coordinates of several locations on the screen, and then move from one place to another without human operation.

The Beidou GPS system does not need to be connected to the network. In fact, this function can be used offline at any time.

However, in the early days, when iron bull x started the driverless mode, it still needed the user's mobile phone to install app, so there was a way to feedback information.

Gradually, more and more data are received in the company's servers. Liang Shicheng seeks improvement by observing these data.

First of all, there is no accident in the whole driverless system. The program code extracted by the universal editor is very reliable, and the program code used in the later stage comes from a carefully selected group of old drivers with more than 30 years of driving experience and no accident.

According to the feedback data of nearly 20000 electric tractors, Liang Shicheng quickly found a problem. At the beginning of the original design, Tieniu x, which can travel 120 kilometers on a single charge, is far from reaching this number in many cases, and the battery is nearly exhausted.

The staff in the company disagreed and explained that it was not a design problem, but that many roads in the countryside were rugged, or some roads had uphill and needed additional power.

In the face of this problem, Liang Shicheng personally led a team to the countryside for investigation. This is not a problem easy to attract other people's attention, or it is common sense.

For traditional cars, the same mileage and rough roads need to consume more gasoline. Of course, the same is true for electric cars. At the same time, they have to endure the bumps all the way.

But he is still somewhat unwilling and hopes to make improvements on this issue.

Things soon took a turn for the better. I accidentally found an old man using a manual wheelchair in the countryside. The old man has rich experience. When the wheel meets a stone, he first accelerates with force, and then forces in the opposite direction, so the wheelchair appears more stable in the whole process.

Inspired by this, and extracted the old man's program code in this process, a patch package is brewing.

The motor controlled by the circuit can change from a motor to a generator only by controlling a conversion of the chip.

And from the battery power supply circuit connected to the high voltage, it is converted to be connected in series with other low-voltage empty batteries.

The whole process can be carried out thousands of times a second. The rugged road surface is equivalent to very small uphill and downhill in some cases.

In order to maintain the overall stability of the car and the speed does not change greatly, we need to increase the force uphill and in the opposite direction downhill like the old man.

For Tieniu x, it can instantly switch to generator mode in the latter case to recover some power resources.

Finally, this patch increased the travel of Tieniu x on rough roads and improved the stability of the car.

After finishing these things, Liang Shicheng plans to reorganize the agricultural equipment company and integrate it into Yilong technology, another artificial intelligence company, so as to facilitate listing and raise more funds.

He is ready to enter the field of driverless electric vehicles from scratch in several years, and is ready to find a reliable start, and then study other fields at ease.

At present, the purpose of letting Tieniu x run all over the street is to prepare for listing, in addition to checking whether there are any shortcomings in the system that need to be improved.

Developing driverless electric vehicles requires more money.

Before a company goes public, it should show itself more potential as much as possible.
