Droneless cars for beginners

Pro unmanned cars constantly flash news, but what really happens in this area? How do unmanned cars drive? Who makes them? Why do they still not go en masse through the streets? Let's try to sort everything out.

What is an unmanned car


 3r33354. This is a car equipped with an automatic control system that can move from point A to point B without human intervention.

How do unmanned vehicles


 3r33354. To arrive at a destination, an unmanned vehicle must know the route, understand its surroundings, comply with traffic rules and correctly interact with pedestrians and other road users. To meet these requirements, the drone uses the following technologies:
 3r33354.
 3r33354. 3r3305.  3r33354. 3r3333317. 3r33333. Cameras [/b] : visual detection of objects, such as road markings and signs
 3r33354. 3r3333317. 3r33333. Radar [/b] : Identify obstacles and objects in front and behind, and determine the distance to them 3r-3320.  3r33354. 3r3333317. 3r33333. Lidar [/b] : similar to the radar, but much clearer and allows you to detect objects around the car (full 360 degrees) 3r320.  3r33354. 3r3333317. 3r33333. AI (artificial intelligence) [/b] : machine brains. It processes data from cameras and sensors, drives a car and makes decisions.

Levels of autonomy


 3r33354. An organization called SAE International has done a good deed and has standardized 5 levels of autonomy, which all players on the market adhere to: 3r33346.  3r33354.
 3r33354. 3r3305.  3r33354. 3r3333317. 3r33333. Level 0 - No Automation [/b] : The driver must control everything - steering, brakes and gas. Normal car.
 3r33354. 3r3333317. 3r33333. Level 1 - Driver Assistance [/b] : The car helps to brake or accelerate. Cars with cruise control are just about level 1.
 3r33354. 3r3333317. 3r33333. Level 2 - Partial Automation [/b] : A car can simultaneously control acceleration and braking, but a person must monitor the situation and be ready to take control. The most striking example of level 2 is Tesla.
 3r33354. 3r3333317. 3r33333. Level 3 - Conditional Automation [/b] : The car can fully control the movement, but at some point may ask to take control. Rumor has it that the 2018 Audi A8 is able to do all this, but so far there is not a single review.
 3r33354. 3r3333317. 3r33333. Level 4 - High Automation [/b] : It can do everything that level 3 can do, but it can also cope with more difficult road situations. In general, you can let go of the steering wheel and do nothing, but if the car is unable to make a decision, it will notify you about it and will gently park on the side of the road. The fourth level is stated by companies such as Waymo or Aptiv
 3r33354. 3r3333317. 3r33333. Level 5 - Full Automation [/b] : Full autonomy, human participation is not required. The car itself makes a decision in any situation, the steering wheel may be missing.

Key market players


 3r33354. Most automakers realized that the future was in unmanned vehicles and rushed to open new departments and buy start-ups. In addition to automakers, not only many startups participate in the race, but also IT giants like Google, Yandex and Apple. Here are the most basic.
 3r33354.
 3r33354. 3r3193. General Motors 3r3194.
 3r33354. Being one of the leading automakers, GM spent a lot of money to stay in the lead for unmanned cars. In 201? I acquired a startup Cruise Automation, which was developing a drone, for more than 3r33318. 1 billion dollars [/b] . Cruise poured a total of $ ??? billion in investment from SoftBank and $ 1.1 billion from GM in 2018. To further dominate the market for autonomy, GM also acquired a lidar manufacturer. GM is testing its UAVs in San Francisco with expansion plans for New York. The first commercial trips of UAVs are scheduled for 2019.

Waymo (technology leader)


 3r33354. The oldest startup was founded in 2009. At the moment, is considered the most perfect unmanned vehicle. Estimated at $ 175 billion r3r3319. (!), Waymo has already traveled a total of 10 million miles by Chrysler, Honda and Jaguar cars. More recently, Waymo announced his plans to purchase another 6?000 Fiat Chrysler for the future of a paid unmanned taxi.

 3r33354. 3r3149.
 3r33354.
 3r33354. 3r3193. Uber 3r3194.
 3r33354. After a very serious lawsuit from Waymo, things at Uber were a bit shaky. Then they shook after the accident as a result of which a man died. However, Uber did not give up, and together with partners like Volvo and Daimler raised $ 500 million of investments from Toyota. Temporarily, Uber drones do not drive on their own, but are driven by drivers, simultaneously digitizing cities into HD maps. Probably in the future, Uber will integrate unmanned vehicles into its taxi service.

 3r33354.
 3r33354. 3r3193. Lyft (taxi service, Uber competitor)
 3r33354. Compared to the aggressive expansion and marketing of Uber, the Lyft approach is more focused. Lyft started with Aptiv, who was once on the verge of bankruptcy. Together, they made more than ?000 paid trips on UAVs (with only 20 cars) in Las Vegas. When ordering a taxi Lyft, the passenger can choose unmanned taxi.

 3r33354. 3r33175.
 3r33354.
 3r33354. 3r3193. Tesla 3r3194.
 3r33354. Tesla has a completely different look at the unmanned future. Ilon Musk believes that the drone can work only on the same cameras (after all, a person drives a car with just a pair of eyes), without lidars. Despite the fact that Tesla cars have autopilot functions, they still tread on the 3rd level of autonomy, and there are enough accidents due to autopilot too.

 3r33354. 3r3193. Baidu 3r3194.
 3r33354. Baidu has been shaking the local Chinese drones boat since 2014. In 201? Apollo announced, an open-source (open) platform for unmanned vehicles. Baidu aimed at mass production of unmanned vehicles from 2019 to 202? but its chances shaken after a number of AI specialists left the company (including Lu Qi).

Why so long? 3r33333.
 3r33354. Waymo was founded in the 2009th and only now they are more or less ready for commercial trips (and even then in sunny California). That is, after almost 10 years. Why so long? Although the unmanned technology race has accelerated over the past 5 years, all companies have common problems: 3r33346.  3r33354.

Lidar


 3r33354. Lidar is essentially a laser machine that constantly rotates and “shoots” a 360-degree laser, producing the distance to each point that it was possible to measure. Here's a video for better visibility:
 3r33354.
 3r33354.
3r33333. 3r33333. 3r33333.
 3r33354. Unfortunately, the lidar costs a lot of money (from ??? rub for 1 piece), and you need a lot of them in an unmanned car (2-5 pieces). It is also impossible to get rid of it, because only the radar and cameras will not be enough to clearly navigate the terrain.
 3r33354.
 3r33354. Various companies are working to reduce the cost of lidar and release a new, cheap solid-state lidar (without rotating elements), but such products are still in development.

AI (artificial intelligence)


 3r33354. As mentioned above, AI is the heart of the car. AI determines objects from cameras, trying to guess who it is (dog, person, car, road sign, etc.), how pedestrians and other cars will behave. In order for such artificial intelligence to work, engineers “feed” him huge amounts of data so that special algorithms can learn from this data. The more quality input data, the better the algorithms will work.
 3r33354.
 3r33354. Although the algorithms have gone far, they are still stupid as a 2-year-old child. A vivid example is the incident with the Uber drone (because of which a person died), the algorithm could not recognize the person on the road (in other matters, as the driver did not have time to notice). But besides a person, one must also “see” many other objects — every car, road sign, traffic light, be able to determine lanes and many other things.

Weather conditions


 3r33354. Let's be honest, almost no unmanned car can ride normally in conditions of snowfall or heavy rain. The exception is MIT University. The guys learned to navigate the casts of the road under the machine.

Cartography


 3r33354. Simple maps and simple GPS accuracy (3–10 meters error) are not suitable for UAVs; a car needs to understand where it is with centimeter accuracy. Despite the fact that the drone has a bunch of sensors, you need to have accurate information about the surrounding terrain (road marking geometry, road boundaries, nearest traffic signs, etc.). All this information is in the so-called HD-cards.

 3r33354.
 3r33354. To keep the mapping up to date special map cars 3r33333. (special car with cameras and lidars) must drive through the streets and “digitize” them. Thus, with the advent of the unmanned car race, the cartography race among such companies as Here, TomTom, DeepMap, lvl? Carmera, Google and others began. In the 21st century, data is new gold.

Infrastructure


 3r33354. Unmanned vehicles require new road infrastructure. And not just an infrastructure, but a smart infrastructure in which cars could communicate not only with the infrastructure itself (signs, traffic lights, etc.), but also 3r-3299. with other cars
. Here are some basic terms:
 3r33354.
 3r33354. 3r3305.  3r33354. 3r3333317. 3r33333. V2V (vehicle-to-vehicle)
- cars exchange information directly with each other
 3r33354. 3r3333317. 3r33333. V2I (vehicle-to-infrastructure)
- cars exchange information with road infrastructure 3r33320.  3r33354. 3r3333317. 3r33333. V2P (vehicle-to-pedestrian) [/b] - cars exchange information with pedestrians (for example, the car sees a pedestrian’s smartphone and understands that there is a person here) 3r3320.  3r33354.
 3r33354.
 3r33354.
 3r33354. For example, a car travels along a highway, and a road sign 300m ahead tells itself “I’m a sign like this, I’m there”. The unmanned vehicle will be able to understand in advance what is ahead and plan its actions in accordance with this information.
 3r33354.
 3r33354.

Human confidence


 3r33354. People still don’t really trust unmanned vehicles. According to 3r33338. a study by Reuters and Ipsos
only 38% of men and 17% of women said they would feel comfortable in an unmanned vehicle. Actually, not surprisingly, the technology of unmanned vehicles is quite young, people did not have time to get used to it. Automakers and startups have yet to win the trust of people.

What's next? 3r33333.
 3r33354. We are witnessing how unmanned vehicles slowly appear on our roads. It is unlikely that in the next 5 years we will see them as a mass phenomenon: neither the algorithms nor the infrastructure have yet grown. However, with the advent of V2V /V2I, special zones of unmanned vehicles may appear, where you can call the usual Uber /Yandex and drive to a drone in half an hour. 3r33333. 3r33354. 3r33354. 3r33354. 3r33352. ! function (e) {function t (t, n) {if (!
