Another mountain of automobile technology, who is more advanced in assisted driving technology than the top three in Japan?

The hottest technology in the automobile industry is not the engine gearbox, but the ADAS advanced assisted driving system, which is another peak of automobile product technology. Different from oil and electricity, ADAS including AD fully automatic driving is recognized as the future direction by the industry. This means that whoever reaches the other side first can go around the field first, and the fan economy is universally applicable.

However, ADAS is not strictly defined and comprehensively evaluated at present, and it is a result-oriented blue ocean market. Generally speaking, both A and B know that there are two thousand gold on the other side, and everyone wants to cross the river as soon as possible. The former is good at water and goes into the water directly with bare arms. The latter is a weak scholar, and his choice is to chop wood and build ships.

Of course, the difference in the world is not that big. They all simulate human driving behavior through perception, judgment and execution, and scientifically improve it. The most difficult of these three parts is judgment, followed by perception, which is what we call "algorithm" and "sensor".

From Navigant According to the Research report released by Research, Japanese players lag behind European and American companies as a whole, and only Nissan-Renault Alliance occupies the position of the first/second echelon in the ADAS pattern because it is close to the European concept, far exceeding Toyota and Honda.

Today, let's take a look at Japanese companies that don't have the advantages of Silicon Valley software and Munich's advanced ideological trend. What are the characteristics and advantages of ADAS at present? There is little information, so guess from some tests and product hardware.

ENCAP, as a third-party testing organization in Europe, values human safety above everything else, so it is also one of the most comprehensive and mature institutions in the authoritative organization to evaluate ADAS. After all, the ultimate goal of ADAS is actually zero accidents and zero deaths, and liberating drivers is only a supplementary right.

In 2020, ENCAP's assisted driving score can truly reflect whether each brand has a good correspondence with ADAS functions of different models.

Although Nissan and Nissan are allied, shopping malls are like battlefields. Judging from their current relationship or separation, Nissan's own achievements are more realistic. The evaluation is medium, which means good. The equipped ADAS system name is ProPilot.

Specific functions include: vehicle-to-vehicle AEB, vehicle-to-pedestrian AEB, lane keeping and cruise control, among which advanced functions are as follows:

Automatically avoiding obstacles, this project got full marks for its daily production of Juke, and Juke only got a good rating, mainly for two reasons. When the adaptive cruise function is turned on, it can't respond timely and effectively according to the driving state of road vehicles. For example, when the car brakes now, Juke's identification is not timely. In addition, the lane keeping function is easy to deviate from the lane when curves and ground guide lines appear alternately.

It should be noted that although Juke only got a good evaluation in the ENCAP score, it is the most comprehensive and difficult evaluation in the world. The entry threshold is L2-level assisted driving, and the basic condition is that the system that helps drivers in both vertical and horizontal latitudes is qualified for testing.

As the champion of the universe sales in the traditional era, Toyota's progress in the field of ADAS does not match its achievements.

In fact, Toyota has many patented ADAS technologies, such as Mobility introduced on 20 16. Teammate events can achieve a high level of automatic driving assistance.

Looking at the products on the market, the ADAS function of Toyota compact car is still limited to the most basic AEB, ACC and LKA, and the price of this configuration is still relatively expensive.

What kind of expressway does Toyota want to achieve for its high-end brand Lexus? Teammate concept, which is also based on the combination of high-precision maps and sensors to realize L3 automatic driving on closed roads, has been in mass production for more than three years, while Toyota is only in the research and development stage, and it will take some time for mass production.

To sum up, Toyota's low-end models still use ADAS as an option to supplement some users' needs. On Lexus, it is necessary to promote the concept of autonomous driving and seek early mass production. However, at the Beijing Auto Show, e-Palette arrived as scheduled and achieved the goal of "releasing self-driving vehicles for the 2020 Tokyo Olympic Games", but the Tokyo Olympic Games no longer exists.

Finally, look at Honda, which may be deeply immersed in the aura of oriental leaders in the field of internal combustion engines. Honda's ADAS input and output has been very small.

The strategy that can be seen at present is that Honda will also strictly distinguish between urban roads and the so-called "high-precision map coverage area", which is currently a part of expressway. For the former, Honda will only give it L2 or below driving assistance, while the latter will be equipped with L3 or above functions.

Is the Honda ADAS function that domestic consumers are currently exposed to Honda? Measuring and reading system

The whole set of functions is very similar to that of Toyota, except that Toyota has a strict supplier system, while Honda is relatively more open to global suppliers, so functions and performance will be integrated. Although Honda has a weak start and investment, it has done a good job in the adaptation of basic functions.

Generally speaking, the Japanese Big Three have different ideas. Nissan is westernized and resigned to the progress of ADAS. It is impossible for Toyota to give up the strategic layout of ADAS, and its volume and financial pressure force it to remain close to the first echelon. Because Honda has its own tonality and doesn't want to break the wind. It is good to supplement its products with mature supplier technology and give full play to its greatest role.
