Driver-Less Cars – Are They the Future?

Even though we are now well into the computer age, people still have a hard time understanding driverless self-driving cars that look like “ Kit ” in Knightrider or the Batmobile in Batman, with their futuristic ability. to maneuver, are part of our new reality. Yet for nearly a decade, Google, the internet search giant, has strived to bring this concept even to American roads. Google’s driverless cars have now driven 750,000 kilometers on the road without any major incidents occurring and the company confidently announces that driverless car technology, at least when it comes to cars on the highway, is a reality. They believe their cars can handle just about any scenario that comes up on the highway. Driverless automotive technology has become hot news, every major automaker is involved in research in this area. Now Google is trying its driverless car technology in cities, albeit with a little less success than on the highway.

The solution that presents itself to most people when driverless cars are mentioned is that it has to be some sort of v2n solution where the vehicles communicate directly with the net via fixed nodes throughout the city, who can keep up with every car and keep the traffic going by diverting and directing the traffic to keep things going. This type of system would be a natural precursor to a driverless car system. Yet Google has taken the diametrically opposite path by relying almost entirely on sensors inside the car that interact and react to the outside world, those sensors associated with intensive mapping applications. and GPS (although currently GPS is only good up to about 10 meters) are used in a combined operation to guide the vehicle. This is likely due to the fact that a grid-connected driverless car solution would involve many repeaters and amplifiers and be prohibitively expensive in terms of power consumption, infrastructure and bandwidth usage. Google should know! Yet the technology Google uses isn’t cheap either, at some $ 100,000, a few thousand dollars, that doesn’t make it a choice for the average person. Apart from that, the focus on inputting the sensors to maneuver the vehicle also makes the technology extremely complicated. The prospects of seeing driverless cars on the streets of towns and cities in the near future don’t look very promising at the moment, although they will likely be a common sight on the highway soon.

Today, an Indian company, Trigon, claims to have invented new driverless car technology that will cost a fraction of Google’s driverless car system and perform almost flawlessly under virtually any condition. Any successful driverless car technology will require split-second timing and excellent coordination and response times in order to be able to maneuver automatically under normal traffic conditions. Rather than trying to solve the problem by charging with a large number of sensors like in Google, Mercedes and Toyota driverless car systems. The driverless car solution designed by Trigon uses LIDAR mapping via a diffuse laser screen of the environment and a minimum number of small cameras. The detailed route information obtained in this way is stored in the cars’ computers. This means that a car would have to be driven on a given route first before it can follow that route on its own. It should be mentioned here that the efficiency and accuracy of 3D LIDAR mapping have kept pace with computers as they improved their performance. It is therefore now possible to carry out 3D mapping in real time. However, the company quickly came to the conclusion that using only cameras and LIDAR output would be time consuming, imprecise, and inconsistent; another solution would have to be found. This is where Trigon made a breakthrough. The reasoning behind the new Trigon driverless technology is simple; all cars have brake lights, all cars have indicators, insurance, license plates, etc. Why not accept the fact that driverless car technology is here, why deny the existence of this technology?

Basically, this means that since the technology is there and has been proven, why not adjust the infrastructure to accept this fact. What Trigon suggests is that all vehicles such as cars, buses, bicycles, etc., whether or not equipped with driverless car technology, must be equipped with the latest RFID tags ( Radio Frequency Identification Tag) capable of relaying information in real time. These beacons will operate vehicle-to-vehicle and not vehicle-to-network and therefore will not impact communications or occupy unreasonable amounts of bandwidth. In fact, these types of RFID tags are precisely used to transport nuclear material. These advanced RFID tags can monitor the temperature, pressure, humidity and tightness status of nuclear packaging and can be read from up to 100 meters without line of sight. The RFID tags that Trigon will use give the dimensions, weight, orientation and speed of the vehicle, no other information will be given, thus preserving confidentiality. RFID tags can be read from a distance of 100 meters (more if necessary) without line of sight and power the car battery using negligible amounts (a few millwatts) of current. This means that any car equipped with Trigon driverless car technology would have a 3D image of the traffic immediately around it in real time, giving the dimensions, speed, weight and line of approach of these vehicles. These RFID tags would cost less than $ 20 to install and if installed in all cars, driverless technology would be a cinch. It would be easier and less complicated than the systems used by the post office to sort letters according to zip codes or even baggage handling machines at airports. It is instead of sensors collecting information and analyzing it, all the relevant information to maneuver the vehicle would come to the vehicle itself, then it is simply a matter of using software based on the old Newtonian laws of motion to maneuver in the right direction at the correct speed. The technology allows up to 2,000 RFID tags to be read simultaneously, which is overkill because cars on the road will interact with up to eight other vehicles in the immediate vicinity at any given time. Also, due to the limited amount of information conveyed, the problem of bandwidth clogging does not arise, it is a problem. non sequitur. What this actually means is that the use of this system is a leap forward in bringing driverless car technology to the roads. Cars can choose to install the technology or not, but all cars that opt ​​for the system will have a working system.

This is not a new precedent, for example, when motor cars were still a novelty, the available roads were found to be too difficult for them to maneuver, leading people to campaign for the ‘ “ good roads movement ”, which caused the US government to start allocating funds to build motorized roads, the rest is history. Cell phones have had a similar experience, it is the establishment of numerous towers and repeaters that have made cell phones and communication all over the world a success. Today, cell phones are as ubiquitous as clothing.

The advantages of implementing such a driverless car system are numerous, starting with safety, economy, time savings and virtually maintenance-free driving. This is because cars use Newtonian laws of motion, where it is necessary to know the loaded weight of the car at a given stage in order to calculate the appropriate speed at which to travel, so the system has a good idea of ​​what the answer is. The car’s “normal” should be, any deviation from this standard performance would be noted, analyzed, reported and hopefully rectified. Another huge advantage of the system is the considerable fuel savings achieved by effectively stopping the starting and running of cars. Traffic jams would be a thing of the past and, as a result, large amounts of fuel would be saved. The preferred driverless car system platform are hybrids like the Toyota Prius or even all electric cars like the Tesla.

It is time for the United States to once again lead the world and set the tone in innovative technologies, driverless car technology could be one of those technologies that can be implemented at a profit.
