Tesla Will Release a Completely Unmanned Vehicle
The American company “Tesla” will soon release an unmanned vehicle of the fifth level. It means that the car will be able to drive on public roads without driver intervention. On July 9, Reuters writes about this with reference to the head of the company Elon Musk.
What Is the Fifth Level?
“I am confident that Level 5 technology or full autonomy will be launched, and I think it will happen very quickly. I'm sure we will have the basic functionality of a Level 5 technology ready this year," such a statement was made by the most famous businessman Elon Musk.
In accordance with the standards of the Professional Association of Automotive Engineers (SAE International), there are 6 levels of automation for self-driving cars. The sixth level means that the self-driving car behaves like a qualified driver. SAE standards are officially adopted by government regulators, engineers, automakers, and investors.
Self-driving cars are vehicles that drive safely on public roads without human intervention; they are controlled by a computer and sensors combined into a single autonomous driving system. The level of autonomy of the system is set by its manufacturer.
As it was mentioned above, the levels are defined by SAE International, the professional association of automotive engineers, and briefly describe how ready a system is to put control of a car into the hands of a computer. SAE categories are now widely used by regulators, engineers, automakers, and investors. By the way, as these standards are international, they have been completed by an international team including engineers, developers, regulators, etc. Most of the professionals have been found in the engineering marketplace as it proposes wide possibilities and truly experienced workers. One of the most popular marketplaces is Engre with a wide range of professionals. For instance, if you are looking for civil engineers , mechanical engineers or you want to find automotive software engineers at Engre platform , you will definitely succeed in this process.
According to the SAE International classification of driver assistance systems or ADAS (Advanced Driver Assistance System), there are six classes of autonomy from level 0 ⏤ fully manual control with the ability to warn of dangerous situations on the road, up to 5 ⏤ completely unmanned vehicle. Categories start at Level 0 (cars with ABS and cruise control are included in this category).
At Level 1, the car already helps the driver a little. For example, adaptive cruise control and steering or braking control appear, but only one of the two.
A Level 2 steering system can control both steering and braking, but, like the previous level, only under certain circumstances. For example, the driver has to intervene on a highway. To put it simply, the car can drive itself, but the driver needs to be ready to take control at any time.
At Level 3, the car has a little more autonomy, which means that the driver has more time to react and take control of the car in any incomprehensible situation. If Level 2 assumes that the driver is always watching the road and is ready to turn on at any time, then at Level 3 the role of the driver is to be in reserve.
With Level 4 automation, the system assumes full control, allowing the driver to rest, but only if all the conditions have been created for this. For instance, there are highly detailed three-dimensional maps so that the system knows where everything is with the accuracy of a couple of centimeters. Most developers try to build systems at this level.
Level 5 assumes full automation. In this hypothetical situation, there is not even a steering wheel in front of the driver's seat. According to the latest Autonomous Vehicle Technology Report 2020, there are no working Level 5 technologies in the world. Experts do not expect such technologies to appear in the foreseeable future: highly automated systems will only be used as advanced driver assistants. However, Elon Musk wants to prove them wrong.
According to the entrepreneur, Tesla will be able to achieve the basic functionality of the new technology during 2020. Now the company produces cars with advanced automation technology ⏤ the autopilot function.
Tesla is also currently developing new cooling systems that will allow more efficient electronic systems to be used in cars.
On June 16, it became known that Tesla introduced a new top-end modification of the Model S electric car, which was designated as Long Range Plus. It became the world's first mass-produced electric vehicle with a range of more than 400 miles (643 km).
Tesla Model S ⏤ The First Electric Vehicle with Range of over 400 Miles
Tesla CEO Elon Musk announced on Twitter that the 2020 Tesla Model S has become the world's first electric vehicle with a range of over 400 miles according to the EPA methodology. This result was demonstrated by the Model S 2020 Long-Range Plus version. Before that, the autonomy of the car was 391 miles according to the EPA method, but since January of this year, improved Model S began to leave the company's assembly line.

The amount of improvements is small, but, as you can see, it significantly influenced the autonomy of the electric vehicle. The 2020 Tesla Model S has new seats and lighter components in the traction battery unit and electric motor, making the car a little lighter. Wheels with improved aerodynamics and tires with low rolling resistance have appeared as well. And only these two measures increased autonomy by 2%. Another 2% came from the improved oil pump and gearbox. The logic of the regenerative braking system has changed ⏤ it is now included in the work at low speeds. As a result, the autonomy was 402 miles.
For some time now, Tesla has not officially published the power of electric motors, but the dynamic characteristics are known ⏤ they have not been changed after the modernization. The Tesla Model S Long Range Plus liftback can accelerate to 100 km / h in 3.8 seconds, the maximum speed is 249 km / h. The price in the USA excluding subsidies is 75 thousand dollars. Also, the most extreme Performance modification has remained in the range. It accelerates to 100 km in just 2.5 seconds, gains 261 km / h, but the cruising range is only 560 km according to the EPA cycle. The rest of the Model S versions (with less capacious batteries and rear-wheel drive) were excluded from the range immediately after the start of production of the Tesla Model 3 sedans.
By the way, Tesla should be aware of its rivals: new electric vehicles by General Motors and Toyota promise to be incredible as well. And their developments don't trail far behind. And who knows who will conquer the world of electric cars after all?
