About prospects of development of intelligent control systems One driverless Tesla has almost thrown its passenger off a cliff, and the other one rode a drunk driver fallen asleep, not paying attention to the police, who tried to stop the car over 13 km. Volvo XC60 with Pilot Assist technology estimated the changed marking on the two-lane road incorrectly during a test drive. When one white dividing strip was changed with two side strips indicating the boundaries of asphalt, the artificial intelligence decided that now the whole road was at its disposal, and passed over to drive in its middle (in Russian). How long do we have to wait for an autonomous control system, and will it be able to guarantee absolute safety? As regards string transport, SkyWay has already taken all of it under control long ago. We highlighted the achievements in the field of automation in October 2018. You will learn about the progress personally at EcoFest-2019 to be held on August 17 in EcoTechnoPark. During the event, experts are going to demonstrate how unibuses run at intervals, in a virtual coupling and perform routing tasks. For example, they achieve a pre-set speed, change it at different sections of the track, and, depending on the actions of other pods on the route, stop for pick-up and drop-off of passengers. All unibuses will be able to "communicate" with each other and receive data on the state, position in space, speed, distance and so on. Regardless of whether they are on the same or on different lines. It is planned to demonstrate various operating modes of the control system. Including an emergency duty, when one vehicle will be able to take another one in tow, conditionally out of order to deliver it to the nearest service station. Artificial intelligence controls not only the parameters of the vehicle and the environment, but also the situation inside the cabin. Today, they are fine-tuning algorithms to identify behavior in the cabin, unnatural position of a body (for example, if a passenger doesn't feel well), left things, payment via FaceID. Professionals from SkyWay Technologies Co. have done a lot for the development of the global control system during the year. After all, it will provide a high level of traffic safety due to removal of the human factor, as well as help to set up passenger traffic up to 50,000 people per hour at 2-seconds interval of movement on the line. This is the performance capacity of Moscow metro, with which SkyWay can be compared by other indicators as an innovative type of non-surface transport. Automated control in metro In railway and, in particular, in underground transport, only some processes are automated. A simpler model is used in them. There is practically no crossing of transport routes in tunnels, and routes are isolated from each other in most cases. Automated train control is manifested in three areas: safety, transport control and traffic monitoring. Trains run according to a schedule and control opening and closing of carriage doors themselves. The autonomous monitoring system traces all routes and the environment transmitting the data to the control center. In addition, the system controls the distance between trains and compliance with the speed limit. Obviously, it was the easiest thing to automate the subway, because the infrastructure is initially isolated, and the same vehicles move in the tunnels. Possibly, if the system is scaled up, it can be transferred to other areas of railway transport. But then there will be problems in monitoring and controlling the traffic of international trains or due to environmental challenges. For example, during the arrival of suburban trains at various types of stations. It is quite obvious that SkyWay string transport, with all the same advantages in terms of automation that the metro can boast up, has additional benefits. In underground transport, you are likely to have already encountered a bad smell, stuffiness, crowding, pickpockets and other "charms" of public transport. SkyWay suggests the possibility of travelling at the height of a bird flight, where you can enjoy the surrounding scenery. One of the stages in developing Skyway road network will be the introduction of personal transportation. Of course, this will require to bring string tracks to houses in the same way as it is now implemented in road transport. In addition, you do not need to be an economist to understand that the construction of SkyWay is sufficiently less-costly than tunneling for subway. World autopilot market There is a standard classification system that defines five different levels of automation: Level 0 No automation A driver has full control of the car and the system does not interfere with driving. This includes warning systems on collision or exit from the lane. Level 1 driver assistance A driver controls the car, but the system can change speed and driving direction of the car. These include adaptive cruise control and lane management. Level 2 partial automation A driver should be able to drive the vehicle if necessary, but speed and steering are no longer his responsibility. This includes parking assistance along with Tesla's autopilot function. And also the system Distronic Plus created by Mercedes-Benz. According to the requirements, the driver should not be distracted in modes from level 0 to level 2. Level 3 conditional automation (humanity is here now) The system fully controls speed, steering and the environmental condition. The person should be ready to intervene when the system asks for it. If the driver does not respond within the allotted time, or there is a failure in the system, the car will stop itself. The driver is allowed to distract only partially, for example, to check messengers, but not to sleep. Level 4 high automation The system fully controls the vehicle and the presence of a human is no longer required, but its application is limited with specific conditions. Unmanned taxi Waymo is an example of high automation. However, it is available only to a narrow circle of people and in a small area. Level 5 full automation The system is capable to control the same parameters as at level 4, but will do it under any conditions. Here man is as important as a cargo. Currently, examples of such fifth level systems do not exist. Consumer Reports (something like a ‘onsumer Union in the US) examined autopilots of 4 automakers. Tesla's autopilot was in 2nd place. Cadillac brand product was recognized as the most technologically advanced and efficient. Propilot Assist system of Nissan took the 3rd place, and Pilot Assist of Volvo ranked the fourth. However, these are not the only players in the market of automated technologies. The company Continental is also engaged in promotion of automated driving. In particular, it develops new sensor technologies and high-performance computer systems. In Russia, the company has developed Mobile additional equipment safety of machinery, which is suitable for all vehicle type and model year. It is installed on the windshield and works as a co-pilot or a third eye. Mobile can't be considered an autopilot. Since the device does not replace the driver and does not relieve him of responsibility for driving and compliance with traffic rules. It only helps to predict a potentially dangerous situation and warn in advance so that a person can react. In Russia, the company Mobileye has developed additional equipment for car safety, which is suitable for all vehicle types and model production year. It is installed on the windshield and operates as a co-pilot or a third eye. Mobileye cannot be considered as an autopilot. Since the device does not replace the driver and does not relieve him of responsibility for driving and compliance with traffic rules. It only helps to predict a potentially dangerous situation and warn in advance so that a person could react. Intel has its own Advanced driver-assistance system (ADAS). Together with Waymo and Mobileye, the company is working on the concept of autonomous driving. The latest models they have released are Chrysler Pacifica Autonomous hybrid minivans equipped with Intel technologies for sensor data processing, general computing and connectivity. This allows them to make real-time decisions and move around in urban environments completely autonomously. However, Waymo was not included in the coalition of companies that signed a document on July 2, 2019 on the paramount importance of safety in the development of driving automation. Zoox, Tesla, Amazon Aurora Pony.ai from Beijing, Nvidia and Yandex subdivisions were not its members, either. They explained their refusal by participation in other projects. What are autopilot system components? Camera is the main source of information. It can identify traffic lights, read road signs, distinguish road markings, classify objects: pedestrians, vehicles, buildings. It cannot recognize the speed of objects and the distance to them. It is not effective in fog, rain and snowfall, as well as under bad light conditions. However, camera is an inexpensive sensor. Radar allows to get information on distances to objects and their speeds. It is suitable for working with remote objects, does not depend much on weather conditions, works in the dark. However, it transfers data about objects over a long distance, covering only a small area. Or on objects that are close, but with a much greater coverage. The cost of radars is higher than that of cameras, but lower than that of lidars. Elon Musk believes that only a camera and a radar will be sufficient for automated transport. And there is no need for the next type of sensors. Although most developers, on the contrary, give preference only to them. Lidars provide a well-detailed picture of what is happening around, determine the distance to objects and their speed. They have a good range and high operational rate. They function excellently in bad weather and at night. Their biggest drawback is the cost. However, Luminar has recently developed a new lidar and called it Iris. It is claimed that its cost will be less than 1,000 USD. Compared to the current 75,000 USD lidars, it seems fantastic. Nevertheless, there is a number of problems that the inventors of autopilots have not yet figured out how to solve:
Former Head of the National Highway Traffic Safety Administration Mark Rosekind said in an interview with the BBC: "The death of people at the stage of testing unmanned vehicles is inevitable. Unfortunately, there will be accidents. People will get hurt, some will die." Therefore, for introduction of autonomous vehicles moving independently on public roads in mass production, it will take a lot of time and victims. And there are no such obstacles for launching SkyWay transport, which means it has much more chances to become a leader. |
