Which one is safer compared to a self driving car or a regular car?

With the progress of society and the gradual development of science and technology, self-driving cars have also appeared around us, which has also been strongly discussed by many netizens, for such things after the emergence of actually to us is also a great convenience, because in many times each of us has a state of self-driving travel, and there will be long-term driving behavior, and in the case of self-driving cars, it will be more convenient for us to travel. For such things, after the emergence of such things, it is actually a problem brought to us by the progress of the times, and here it can also be used to free our hands. <>

Accidents and surprises in life, we never know which will be around us, and for some flying accidents to bring us is also a big blow, after these things we have no way to avoid reasonably, what we can do is not to let them happen around us, drunk driving such a thing after the appearance of please give us a big blow, In this case, we can also see the superiority of self-driving cars, because for such things after the emergence of a series of conveniences for some people who can't drive cars, because in many cases there is also a driving problem when we travel, and for some novices on the road, many times it will cause a series of accidents. <>

After the emergence of such self-driving cars, it actually brings us a lot of doubts, after all, in this case, isn't this also an invention that turns oneself into a "lazy person"? In fact, there are pros and cons to such things after they appear, and we must recognize them in order to get a good solution. <>

It should be safer to drive an ordinary car, because people's reactions are still relatively fast.

I still think that ordinary cars are safer, because after all, there are still people who control them, and I still believe in human abilities.

Which one is safer compared to a self-driving car or a regular car? I think it depends on the situation, if it is under normal driving conditions, then ordinary cars are definitely safer than self-driving cars, but we know that many times when people are driving cars, some people are in a state of fatigue, then at this time self-driving cars are much safer than ordinary cars.

Looking at it now, it feels like ordinary cars are safer, and self-driving car technology is not so mature. I can't tell what to say in the future.

Self-driving cars are safer. After all, it is the latest technology invented by so many scientists, which contains a lot of technologies that can protect life safety, and automatic driving is also more standardized, and there will be no illegal driving.

Autonomous driving technology can timely avoid human-caused risk factors such as road risks, blind spots, and fatigue driving, which are difficult for human drivers to distinguish with the naked eye, and greatly improve the safety of driving.

Taking Tesla as an example, in the third quarter of 2020 vehicle safety report released by Tesla, driving activities involving Autopilot reported an average of one traffic accident every 4.59 million miles. On average, one traffic accident was reported every 2.42 million miles driven in driving activities without Autopilot. At the same time, according to the latest data from the National Highway Traffic Safety Administration, the average U.S. crash occurs per 10,000 miles driven.

Autonomous driving models include: Tesla Model X, Volvo XC90, Audi Q7, etc. Self-driving cars, also known as driverless cars, computer-driven cars, or wheeled mobile robots, are a kind of intelligent cars that realize unmanned driving through computer systems.

Autonomous driving technology relies on a number of sensors and computers, including cameras, radar sensors, and laser rangefinders, to understand the traffic around you and navigate the road ahead with a detailed map (a map collected by a manned car).

According to the level of automation, there are four stages of autonomous driving: driver assistance, partial automation, high automation, and full automation, and many engineers and technology companies are actively developing autonomous driving technology.

Autonomous vehicles can enable people to carpool, dramatically reducing the use of cars and creating the "highway trains of tomorrow". These highway trains reduce energy consumption and increase capacity on major roads. In terms of time savings, the U.S. Department of Transportation estimates that people spend an average of 52 minutes commuting to work each workday.

In the future, people can use this time in a more efficient way.

Security

Self-driving cars have always been equipped with drivers. Our highly trained drivers follow the car at all times, and they can take over the car as easily as if they were disarming cruise control. In addition, we have trained software operators in the passenger seat to monitor the software operation.

Before all the tests are carried out, we send a driver to drive a normal car to understand the route and road conditions.

By adding features such as road markings and traffic signs, the in-vehicle software can familiarize itself with its surroundings and special features in advance. Also inform the local area in advance of work**.

Let's start by explaining what a self-driving car is: in layman's terms, it's a smartphone with four wheels. Once the destination is set, the car plans its own path and drives itself to the destination.

Self-driving cars include: Tesla Model X, NIO ES8, Xpeng P7, Volvo XC90, Audi Q7, Jidu Automobile, etc.

1. Sensor technology: Self-driving cars are equipped with various sensors to understand the surrounding environment, roads, and traffic conditions. Optical cameras include single cameras, multiple cameras, Doppler radar includes short-range radar, long-range radar, and lidar is the rotating machine on the roof of the car, GPS positioning device, etc., which constitute the eyes of the car to understand the environment.

2. Chip technology: that is, it can process the data collected by multiple sensors and integrate a super chip similar to a small computer, which greatly reduces the volume and cost of the "total computer" of the car, and can be applied to the car. Otherwise, there will be no place for people to sit in the car, and ordinary people will not be able to afford cars with these huge computer clusters.

3. Operating system: The computer control system combines the processing results with the operating hardware to realize acceleration and deceleration, braking and parking, changing direction and avoidance, and man-machine dialogue. Driverless cars have the ability to replace human manoeuvres.

Autonomous driving level.

L0: The vehicle is completely controlled by the driver, the driver has absolute control, and there is no automatic driving technology on the car, L1 The driver still needs to drive the vehicle, but there are safety systems such as ACC adaptive cruise, which plays an auxiliary role in the driver's driving, and the hands must not leave the steering wheel, and the eyes must not leave the surrounding road conditions.

L2 At the L2 level, autonomous driving technology can take over some driving tasks for a short time, and the eyes and hands can get a short rest, but they still need to be ready to take over the driving task at any time, because it is not enough to cope with the changing traffic conditions.

L3 comes to the L3 level, which can be regarded as autonomous driving in a sense, and can also be called the beginning of real autonomous driving. The driver can take his hands off the steering wheel and his feet off the pedals.

L4 Level 4 can be said to be autonomous driving in the true sense of the word, there is no need for the driver to take over at any time, and there is no need for the driver to intervene, you just need to sit in the driver's seat and do what you want, and the technology will do the rest.

The most important thing is artificial intelligence. Artificial intelligence is the equivalent of the driver's brain.

There will also be some assistive technologies, such as laser measurement, acoustic measurement, motion sensors, GPS, etc., which are equivalent to human eyes, ears, nerve sensation, etc.

At present, many of these auxiliary technologies are very mature, even far beyond humans, such as laser and acoustic measurement technology, which are currently used in very high-end vehicles, which can carry out ACC automatic cruise. There is also night vision technology, which can help drivers see people, animals, and obstacles up to 100 meters away on pitch-black pages, which are far beyond the physiological limits of humans.

But artificial intelligence is still in its infancy. In other words, the limbs and senses of the autopilot are already very good, even more than humans, but they still lack a brain...

Changan CS55

As the protagonist of this L3 road test, Changan Automobile's research level for autonomous driving is undoubted. As early as two years ago, at the Smart Expo, Changan Automobile displayed the eMotion EV460 model with L4 autonomous driving, which was at the forefront of the industry.

Subsequently, the launch of Changan CS55 has made Changan a veritable "first brother" of its own brand autonomous driving, this model combines low price and high intelligence, and it is also the first independent brand model equipped with L2 autonomous driving system.

Changan CS55 is equipped with IACC system perception hardware for camera + millimeter wave radar, similar to Tesla, the current system has been honed for 2 years, and the safety performance has been very guaranteed.

2. Geely Binyue.

After Changan, Geely, another major domestic manufacturer, also began to install the L2 level automatic driving system on its own models, and the first to benefit was naturally the two models of Binrui and Binyue.

As two models aimed at younger consumers, their styling is trendy enough, and it is clear that Level 2 autonomous driving is another big selling point. Taking Binyue as an example, it can achieve ACC adaptive cruise in the full speed range, and the AEB-P urban pre-collision safety system can recognize vehicles and pedestrians above 80cm, plus the cooperation of other ADAS systems, it already has L2 autonomous driving capabilities.

Note: Although there are many types of vehicles, the structure is similar. This should be said to be the credit of standardization, but also the need for large-scale production lines.

With the development of society, the progress of science and technology and the change of demand, the shape of railway vehicles has begun to change, especially the passenger car is no longer the same old face. However, their basic structure has not changed significantly, but the specific parts have a more scientific and advanced structural design.

Generally speaking, the basic structure of the vehicle is composed of five parts: the car body, the undercarriage, the running part, the coupler buffer device and the braking device. The body is the part of the vehicle that is used to load goods or passengers, and is the basis for the installation and connection of other components of the vehicle. The body of the early vehicles was mainly made of wood, supplemented by steel plates, bow rods, etc.

In modern times, the car body is mainly steel structure or light metal structure.

Self-driving cars are:

1、model x

Official guide price: 10,000.

Class: Medium to large SUV

The Tesla Model X is a pure electric mid-to-large SUV that has excellent range and can reduce consumer concerns. In the running state, the power performance and seat wrapping of this car do not have much shortcoming, but there is still room for improvement in the auxiliary driving function. The rear legroom of this car does not have much advantage, but it is more than enough for family users.

2、model s

Official guide price: 10,000.

Class: Medium and large sedans.

Tesla Model S is an imported new energy model, its exaggerated acceleration experience and complete innovative technology in the market few rivals, as a family car Model S interior space performance is not outstanding, but the seat wrapping is satisfactory, the volume of the tail box is also in line with the performance of the model.

The workmanship of the center console does not have an advantage, but the materials used are worthy of the level of 800,000 yuan of this car. The driver assistance function can be seen as one of its major selling points, but the real driving experience is not particularly good, and it needs to be improved.

3. NIO ES8

Official guide price: 10,000.

Class: Medium to large SUV

NIO ES8 is a medium and large pure electric family SUV, with a NEDC range of more than 500 kilometers is okay in new energy vehicles, and the performance is also very strong, 0-100km H is less than a second.

Positioned as a family car, its selling point is high quality and good experience, which can be described as equal compared with traditional luxury cars. There is only one deficiency, this car is too large and quite weighty, so the power consumption is not low, and it can be seen from here that new energy vehicles do not mean that they are energy-saving.

Geely Binyue. (Geely Binyue is Geely's first BMW module SUV, Geely Binyue is equipped with L2 driver assistance systems, and it is also the cheapest SUV with L2 driver assistance systems we can buy.) Tesla series.

Volkswagen Tanyue.

Autonomous driving is divided into six stages: L0-L5, which are mainly no automation (L0), driving assistance (L1), partial automation (L2), conditional automation (L3), high automation (L4) and full automation (L5).

At present, only the cars with autonomous driving functions on the market around the world have reached the L2 level. In the L2 level, human intervention is still the majority, so it cannot be called autonomous driving in the precise sense of the word, but can only be called a "driver assistance system". Therefore, there is currently no commercial model that can achieve autonomous driving in the true sense.
