Do you know that a modern advanced vehicle has about 100 million computer codes? It is true that such a vehicle has more computer technology than some jet fighter. You can actually have 30 computers or maybe 100 cars. A computer here is not a computer you would normally see. But it’s a computer that responds to a command and has its own. These computers are called microprocessor-controlled devices or sensors in English. These are different from the computers we see in everyday offices or homes. That is, these computers can only do a limited amount of work. But that’s enough. We call it Dedicated Microprocessor-Controlled Devices
For example, think of a gatekeeper on an unprotected railroad. He’s on time. To that end, he remembers the time when the train arrived yesterday. He closes the gate. He can hear the sound of the train first. Then the train passes by. After the train passes, to the other vehicles, he finally opens the gate. Look, this process and his role is very simple. Now suppose the vehicle’s computers are designed to work with simple commands. But what if he did not close the gate when the train arrived? We will discuss that in the next article
Let’s call this machine short, this time. This lamp is written for people who don’t know anything about computers. So, these machines are connected to many things in the vehicle. Cruise control, brakes, vehicle driving speed, radio, ignition system etc. are all involved in this process. Let’s take one example. As in the early days, most vehicles don’t have cables to control the fuel from the accelerator to the lower engine power. Nowadays, when the accelerator is pressed in the leg, you turn it into a volume control that increases the sound of a radio. It is directed to a machine. The throttle body commands the machine compared to several other signals that it receives. What are some special advantages or advantages? 
If you want to increase the speed of the vehicle in the early days, open the carburetor gas. The gasoline then evaporates and the engine goes in line with the speed of the wind. (Please see the first tidbits about operating the carburetor.) No other factors are being looked at here. The driver alone determines the amount of gasoline needed for the ride. This is not correct. If you use a machine, you can do it very accurately compared to other factors. For example, the right amount of oxygen from the wind can get into the engine of the vehicle. So you know that the optimal ratio for mixing gasoline and gas is 1: 14.7 with this machine. Since the original method, that is, the amount of gasoline in the engine from a cable does not affect the other things, the above ratio can be changed and the efficiency of the vehicle can be reduced.But there may be other problems with the use of these machines. Because of a faulty command, one signal may be mistaken for a vehicle, which can increase the speed of the vehicle. Such cases have been recorded. As you probably remember, most Toyota vehicles in America were redesigned. As such, the design of the machines and software required to do so is extremely complex. Because the safety of the vehicle and its passengers should be given first priority.Simply put, a computer has two parts. One is what you might see. We call it hardware in English. For example, a keyboard, a hard drive, or a hard disk, monitor, mouse, etc. are the hardware. The other is the command-based command system, which has data attached to it. We call it software in English.Let us take an example. You pick up a smartphone. Now that smartphone has been made from various pieces of the factory. Suppose that is the final design of the model. That is, the production line that made that phone has been set up. You can’t change that on the way. So that smartphone is now on sale from the factory. Now if there is a problem with this cell phone, it is not practical to take it back to the factory. If this is the case, you can change the software on the smartphone without changing the hardware and fix the mess. We call it a software upgrade in English. Now that the phone is so popular and well-sold, the engineers who designed it will not just be there when they start selling it. They look at complaints from all over the world. As mentioned earlier, the phone has two designs. We say it in English, both Hardware and Software.
The software makers are resting, but the software developers are constantly looking at that phone. If there is a problem, they change the software. They change the phone and fix the problem. So you can fix the mess without touching the hardware. You can connect to the internet and put the new software on the phone. It says, in software, how software upgrade is used.There are occasionally hardware upgrades. But it is rare. Because doing it is more expensive than a software upgrade. Let me say the above in another practical way. Let’s take a high-end world-famous camera at a television company. At some point there is only one software version. Let’s say that plane is 3.5 software instances.Meanwhile, the company’s software engineers, according to reports from around the world, have realized some of the pitfalls in the 3.5-degree software and are building new software called Software 4.0. They inform the agents of that company. Those guys are loading the latest software upgrade for the camera.The same phenomenon is the vehicle. The above two examples were written to show how different technological strategies are used in the same technological platform. However, it is not usually easy for a driver to upgrade software on a vehicle today. But this situation may change in the future. There is an intermediate stage in this system. That is, when you take your vehicle to a garage for questioning, you may have seen a machine called a Scanner plugged into the vehicle. It will help you locate and resolve the problem you encountered in the vehicle.Now you want to know what the job of a computer is. These computers are so connected because they do their job very efficiently. This is not common in vehicles. Computers are connected to every field. The above two examples illustrate this. The above software upgrade is involved. Especially in the future cars we will see in the future, you will see a lot of computers
In a post I wrote above, you may have seen an old Benz bus. The most distinctive feature of modern buses or trucks today is the presence of “Dedicated Microprocessor-Controlled Devices”, as are many other factors, as well as sensors, or, as stated earlier. But having electronic components like this requires a lot of conductors to carry the vehicle’s electrical signals. It is a low loss. We will discuss later how to reduce them. So just like hacking a computer, why not hack a vehicle? A vehicle with 100 computers is more a computer than a vehicle? In the next few days, we’ll talk about how to reverse engineer (and hack someone) the shortcomings of these computers
