  7. Overcoming "obstacles" while moving...

[YesAuto Fresh Technology Interpretation] When I was a teenager, a TV series “Knight Rider” from the United States gave me an unrealistic desire-to have a handsome man who can “speak” and can drive autonomously, just like KITT in the film. car. Time flies, and there are more and more private cars on the road. Among them are also equipped with a voice operating system that can talk to people, but the content of autopilot seems to remain in my dreams. Is this really the case?

■ What exactly is autonomous driving?

In the film and television works, most of the cars with autopilot function are avant-garde in appearance, and there may be a lot of screens flashing various images and incomprehensible content like celestial books. They can very intimately “guess” the mind of the car owner and save it. The owner is in the midst of fire and water. Okay, let's stop brainstorming and take a look at these autonomous driving systems in reality.

The autopilot we imagined is actually called Autonomous vehicles or Self-piloting automobile, which is more appropriate. It is the highest level of computer-controlled vehicle driving, and its development time can be traced back to the middle of the last century. Like many other things, autonomous driving actually has a process of gradual technological development. In other words, autonomous driving also needs to be divided into different stages.

At present, most scientists, scholars, and car companies divide autonomous driving into three stages, namely, assisted driving, semi-autonomous driving, and fully automatic driving. In other words, if your car is equipped with functions such as adaptive cruise, lane keeping, etc., it can be called a car with partial automatic driving functions.

There are many factors that affect the popularization of autonomous driving technology at this stage, which can be roughly summarized as the 6 points shown in the figure below. Among them, those laws and regulations that have been “tested” for many years protect people's safety on the one hand, and on the other hand, rules similar to the “provided full-time control of the vehicle by the driver” marked in the Vienna Driving Convention of 1968 also restrict the development of new technologies. Promotion.

Careful friends may have discovered that in the above table, there is a social and public concern that hinders the popularization of technology. In this regard, relevant agencies have conducted a sample survey of the German and Chinese people, and the results reflected are consistent with yours. There may be quite a difference in what is envisaged.

Through the data, we unexpectedly discovered that the acceptance of autonomous driving technology by the Chinese people far exceeds that of the German people. In addition, the increasing disapproval rate of the German people as they age does not appear in the minds of Chinese consumers. , Which shows the thirst of our people for new technologies.

■ What is the current stage of autonomous driving on the market?

At present, most brands of assisted driving systems on the market are actually the initial stage of autonomous driving. Most of them can provide car owners with important or useful driving-related information or improve driving safety. Let’s take a look at each of the three representative brands. Direction of development.

● Volvo Autonomous Driving

As Volvo, which has always regarded safety as the keynote of its own brand, it has equipped its models with assisted driving systems early on. The name of City Safety has also become popular with Volvo's publicity.

Volvo, a brand that has always advertised safety, has always been in a leading position in active safety technology. This is exactly the technology equipped in the initial stage of autonomous driving technology, which makes us look forward to its announced autonomous driving technology. So, apart from it, what are the results of the research and development of different “tonality” brands of autonomous driving technology?

● BMW Autonomous Driving

Unlike Volvo, the character of the BMW brand has always been inseparable from the control. As the predecessors said, it is not difficult to run fast, but to stop. In the field of autonomous driving, BMW has never been idle.

● Toyota

As an Asian car company, the tone of the Toyota brand seems to be different from that of European and American car companies. The pursuit of balance and moderation are the impressions left by Toyota before. In terms of autonomous driving, its path is also the same as that of the two brands mentioned above. Quite different.

First of all, in 2014, Toyota announced the active safety technology package it developed in Japan. This system called TSA (Toyota Safety Sense) includes a new panoramic mode image monitoring system, an adaptive high beam control system, and a second Many active safety technologies such as intelligent parking assist system. Regarding this part of the content, we have conducted a detailed experience before. Friends who are interested in this part can click “It's Time to Take a Review of Toyota's New Active Safety Technology” to read.

In addition to this part of the technology that has been disclosed to be equipped with new models, Toyota has some secret weapons, which is the Intelligent Transport System (ITS). Its special feature lies in the detection and signal communication of other vehicles and pedestrians by ground equipment, vehicles, and effective prompts to drivers, so as to achieve the purpose of preventing collisions and improving traffic safety.

● Nissan automatic emergency avoidance system

After tasting the “various meals” above, let's have a “dessert after meal”. Compared with those self-driving systems with various functions, Nissan's system called automatic emergency avoidance seems more practical. It can effectively cope with the increasingly complex traffic conditions in the city. When a pedestrian suddenly enters the lane, the system can judge the situation by itself and operate to avoid it, but if it encounters a one-way traffic lane, how this system responds remains to be seen .

Full text summary:

Like the birth, promotion, and popularization of many other new things, autonomous driving is also experiencing such a painful period. Technically, the high computing power and high cost of core components are not the biggest problems that hinder its promotion. Traditional key constraints, laws and regulations, and inter-industry interest relations all restrict its promotion. Autonomous driving is still a long way from truly entering our lives.
