Tesla Model 3 wanted to show how it handles autonomous braking. She failed perfectly

Autonomous emergency braking is a useful assistant that can prevent accidents. But you can’t rely on him.

Autonomous braking systems are relatively advanced today and also include pedestrian detection. Theoretically, they should be able to stop the car not only in front of a larger obstacle or another vehicle, but also in front of a pedestrian.

However, we have seen several times in recent years that this assistant cannot be relied on. Videos can be found on the Internet (found below) showing how cars of some brands have failed tests and demonstrations of autonomous braking. Of course, this is not the rule, but it can happen.

The last time the Tesla Model 3 failed in the demonstration of (in) autonomous emergency braking capabilities is funny. that “the safest car you can drive is a Tesla.”

Model 3 failed during a demonstration of Tesla’s security systems in China. During the test, the electric sedan knocked down a dummy that simulated the pedestrian’s path across the road.

The second video is also interesting, showing a test of another Model 3, because we have the opportunity to look into the cabin. The car can probably recognize the “pedestrian”, it indicates what is happening on the touch screen, but probably too late.

If it was a real person, it probably wouldn’t have worked out for him at all. Or that Tesla would be so fiercely intelligent that she knew she was just a dummy and thought she could sweep her off the road …?

U.S. President Donald Trump, addressing supporters in Dayton, Ohio, statedthat if he wins the presidential elections in November, Iran will sign an agreement on nuclear weapons as soon as possible.

“When will we win [на выборах], about nine seconds after this victory, we will get a call – and it will be Iran, willing to close the deal, ”said Trump.

According to the president, the current US administration wants Iran to conclude this deal. He stressed that Washington wishes only the very best for Tehran and wants this country to be strong. “[Но] they simply cannot have nuclear weapons. That’s all. It’s very simple, ”Trump said.

MOSCOW, Sept. 19 – RIA Novosti. Supersonic strategic bombers of Russia Tu-160 set a world record on Saturday for the range and duration of a non-stop flight for aircraft of this class, the commander of the long-range aviation of the Aerospace Forces told reporters (VKS) lieutenant general Sergey Kobylash“Today, a new record for the range and duration of flight on the Tu-160 supersonic strategic missile carriers was set by two long-range aviation crews. The Russian Aerospace Forces pilots were in the air for more than 25 hours, having covered over 20 thousand kilometers,” Kobylash said. He added that “no one has flown on an aircraft of this class longer.” The previous record in 2010 was also set on the Tu-160, which spent 24 hours and 24 minutes in the air. As the Ministry of Defense specified, the flight of two Tu-160s took place over neutral waters of the central part Arctic ocean, The Pacific, Kara Sea, Laptev Sea, East Siberian, Chukotka, Barents Seas… The missile carriers took off and landed at the airfield Engels… The commanders of the crews are Major General Oleg Pchela and Lieutenant Colonel Sergei Volkovitsky. The department added that during the flight the Tu-160 performed three air refueling from six Il-78 aircraft. “At certain stages of the route, strategic missile carriers Tu-160 were accompanied by Su-35S fighters, as well as aircraft of foreign countries,” the ministry said. The flight of Russian bombers took place in strict accordance with international rules for the use of airspace.

Brembo has given the brakes a mirror finish, it’s not just about looks

Shiny discs should last longer and also place less of a burden on the environment.

Brembo, a renowned manufacturer of brake system components, has introduced new brake discs called Greentive, which you will definitely not miss. Their surface is mirror-shiny and will undoubtedly literally shine from behind the wheels.

However, the glossy appearance of Greentive brake discs is not only aesthetic but also practical. The new discs should offer longer life, better corrosion resistance and lower brake dust emissions. The discs will not stain the wheels and at the same time contribute to the protection of the environment and the health of passers-by.

The specific glossy appearance of the blades should be the result of a process called Velocity-Oxy-Fuel technology, in which the blades are covered with a special coating. At the same time, it should remain on the discs for the entire period of their use, as Brembo confirmed at the request of colleagues from Motor1.

In addition, the discs bear a small Brembo logo, which is also not just for show. This should be a clear indicator of disc wear, so you can see at a glance how much material is left on the brakes.

In addition, the company indicated that this surface treatment technology could be applicable to most disc brakes produced, including two-piece floating brake discs. In the future, we can probably look forward to the widespread application of this technology.

For the time being, however, Brembo will target mainly manufacturers of electric cars and vehicles with alternative drives, which are increasingly looking at the cleanliness of brake discs and brake dust emissions. After all, the ecological direction of Greentive discs is already recorded by their name, which is composed of the terms “Green” and “Distinctive” – ​​ie green and distinctive.

Unfortunately, Brembo has not yet announced the price or the planned start of deliveries of Greentive discs to the market. But when they appear in the underpasses of the first models, we will definitely not miss them.

Autonomous driving: real-time data should prevent accidents

The topic of safety is essential for the question of whether self-driving cars will establish themselves on our roads. Because even if it should be technically possible to let them drive, there remains a moral dilemma: the vehicles must not cause accidents. That would have consequences not only for those involved, but above all for the manufacturers. Because then they face complex legal proceedings and possibly even substantial claims for damages. That is why researchers and industry are working on making the algorithms of their autonomous cars “in a row”.

An algorithm for spontaneity

The biggest problem with safety for the autonomous vehicles is the way they learn. So far, developers have been relying on algorithms that learn certain decisions or are programmed directly. On the road, for example, the cars then know that if the opposite lane is clear, they can overtake. But what if suddenly a child jumps out onto the street? Then the person can react spontaneously, but the machine not necessarily. Because so far the development teams have relied on testing these decisions for their compliance with the traffic rules.

A research team from the Technical University of Munich (TUM) is now taking a different approach: they have developed an algorithm that is supposed to make autonomous vehicles safer. The article about it is in the trade magazine Nature Machine Intelligence released been. In the process, this test takes place live while driving. In this way, the algorithm can also react to new things – for example to situations that were not considered during design or that did not occur in test operation. The Munich team writes that the car can never cause an accident itself and always make “legally binding” decisions – even if it were involved in an accident by other road users.

A plan in hand

By monitoring real-time data, the TUM algorithm ensures that the autonomous vehicle always has some kind of plan in hand to be able to react to the traffic.

Since, of course, no algorithm can be trained for all conceivable traffic situations, the researchers rely on a framework that continuously calculates a kind of corridor in the background in which no accident can occur – provided the other road users adhere to the traffic rules. To a certain extent, the Munich algorithm uses what is happening around the car to calculate plans that the vehicle can use should something surprising happen.

The research team tested this approach using real traffic situations recorded in an urban environment, it said. They played it to the algorithm and it never suggested an unsafe route.

Wrong impression of absolute security

The plan in hand, which protects against accidents, almost sounds a little too good. That is how other experts see it.

Marcus Nolte from the Working Group on Electronic Vehicle Systems at the TU Braunschweig criticizes the fact that laypeople in particular have the impression that the new algorithm guarantees that the autonomous vehicle can no longer cause accidents. But there is no such absolute security and the work of the Munich-based company does not give such a guarantee, said Nolte. The problem is that it is assumed that all road users behave in accordance with the rules.

Then the framework does not deliver a guaranteed collision-free trajectory as soon as someone does not follow the programmed rules.

And Nolte adds: “Something like that happens again and again in daily traffic – for example, driving over solid lines or restricted areas because someone has parked in the second row.” Thus, the algorithm ultimately has the same disadvantage as other model-based approaches: “In the end, a statement is as reliable as the worst model assumption.”

MOSCOW, Aug 30 – RIA Novosti. Hero of Russia Colonel General Nikolai Antoshkin commented on the accusations of the Air Force command USA in Europe and Africa to the Russian pilots. The American side called their actions when intercepting a B-52H bomber over By the black sea unprofessional and unsafe. Antoshkin noted that such a task in peacetime is not difficult for the aces. “Our pilots always prove their professionalism in conflicts, it is always visible there, and intercepting, approaching an aircraft is a simple, elementary task. signals, maybe some, there is no need for special professionalism, “Colonel-General told RIA Novosti. He noted that Russian pilots are well trained, and the planes they use, Su-27, are very easy to control, so intercepting a bomber with their help is “very easy.” According to the expert, the Americans are constantly trying to blame Russia for various incidents. over the Black Sea to intercept the detected air target. It is noted that the crews of the Russian fighters approached a safe distance to the air object, in which they identified a strategic bomber US Air Force B-52N. The foreign military aircraft turned away from the border, after which the Russian fighters returned safely to the home airfield. It is noted that their flight took place strictly in accordance with international rules for the use of airspace.

Well, one should not have expected other words from the Air Force general. This was when the country’s air defense was there, there were specially trained interceptor pilots who knew the rules of action in foreign or neutral airspace in peacetime. The general was in command of the front-line aviation, which only knows how to shoot down the enemy (which he says, not even realizing that he is talking nonsense). The front-line fighters do not know what to do with aircraft that have not violated the state airspace and therefore they are simply hooligans.
