The development trend of fatigue driving early warning system is to combine with ADAS function

According to the relevant statistical data, among the major traffic accidents on the expressway, the accidents caused by fatigue driving account for more than 40%. The effective early warning and control of driving behavior is the core factor to reduce the accident rate.
However, the concept of “driving fatigue” is still lack of a clear definition, and the judgment of driving behavior will be affected by individual differences.
In the process of improving technology and relevant standards, it has also attracted enterprises from different roles, including traditional auto parts manufacturers and AI vision startups.

Front loading is still blank, and the overall market is still passive
It has been 13 months since the Ministry of Communications issued the decree last year that operating buses over 9 meters must be equipped with a front view. Insiders said that although there is still a certain buffer period from the actual implementation, this policy will certainly be implemented in 2018.

At that time, the 9-meter bus without front view will not be able to obtain the safety certificate, and the mandatory standards force the market to respond. However, from the perspective of functional safety, AEB function can not achieve 100% safety in all scenarios after all, and fatigue early warning (or driving behavior monitoring) is a bonus to AEB.
Although there is no mandatory standard for fatigue driving early warning system, for suppliers, ADAS can play a limited role in the short term. At the same time, the market recognizes the role of fatigue driving early warning system in active safety, especially for the long average driving time of commercial vehicle drivers, which is more prone to fatigue, Many suppliers have shifted their business focus to the fatigue driving early warning system.
Although the market prospect seems good, in fact, many suppliers of fatigue driving early warning system are out of interest, which promotes the implementation of fatigue driving early warning system.
In the commercial vehicle market, in order to take a share in the field of active safety, many suppliers have accelerated their speed. For the forward-looking part, a complete set of SOP can be completed as soon as February and March next year. According to the previous speed, it takes nearly a year to complete a complete set of SOP.
However, there is only more than half a year left between now and February next year. It is difficult to say whether this behavior is the accurate control of the market or the rush to act just because of the selling points and market opportunities of the products.
In this process, although the cost of commercial vehicles is also one of the issues to be considered, most of the products used in commercial vehicles are promoted by the government and purchased uniformly, which is the main driving force of the fatigue driving early warning system carried on commercial vehicles.
In the passenger car market, the popularity of fatigue driving early warning system is very low. As the main consumer group in this part of the market, private car owners have different needs for products from commercial car owners, and there are few real safety considerations. Their purpose of using products is more because of freshness.
According to the monitoring data of ggai, by the end of last year, the penetration rate of passenger cars equipped with fatigue warning function was only 11.48%, and the actual production and sales accounted for less than 5%. Among them, the price of most configured models was more than 350000 yuan. Most of the suppliers were overseas manufacturers.
Especially for passenger cars below 200000, the installation cost of equipment is a big problem. The product combined with infrared camera and algorithm needs at least 1000 yuan. In addition, the practicability of the product is relatively low compared with passenger cars. Under comprehensive consideration, the possibility of selection by domestic users with high price sensitivity will be greatly reduced (especially most models choose the optional mode).
As for suppliers, they all want their products to enter the front decoration, so as to ensure stable and visible business income. A number of suppliers and principals of main engine manufacturers told Gaogong intelligent vehicle that there is no real front loading early warning product in the market at present.
The existing products are mostly installed in front of the sales end of some models through the 4S store. There is still a certain distance between such “quasi front loading” and the real “landing” of the fatigue driving early warning system.
The trend of integrating ADAS scheme is obvious
At present, the development trend of fatigue driving early warning system is to combine with ADAS function to realize the integration of in cabin and out cabin safety.
For example, if the fatigue driving warning system is combined with the functions of AEB, it can not only remind, but also realize autonomous braking in dangerous situations, and the safety will be greatly enhanced. It can be said that only when the fatigue driving early warning system is combined with the forward-looking ADAS function can a complete closed-loop ADAS system be formed.
The future fatigue driving early warning system may be based on one platform, integrate internal and external vision, realize systematic safety assessment and risk prediction based on the same chip computing platform, and respond by relying on preset programs.
This safety concept has great potential in the market of “two customers and one danger”, and it is also a key breakthrough field for many suppliers at present. In addition, all kinds of dangerous goods transport vehicles, heavy vehicles, port vehicles, including railway dangerous goods transport vehicles, are now the competitive markets of major suppliers.
The development of fatigue driving early warning system products is a long-term process. The fusion algorithm and hardware also involve image recognition. It needs to accumulate and debug the sample database for a long time, and there is no shortcut in technology.
However, at present, the R & D and production of fatigue driving early warning equipment in China is still in a passive state. More suppliers frankly say that at present, there are few domestic suppliers who have completely independent research and development, and even many are replicating. To be stable and accurate, a large number of data improvement iterations are required. It is not only a matter of time, but also involves economic benefits. Many problems need to be overcome in the process.
The OEMs said that the biggest bottleneck in the technical solutions of domestic suppliers is to develop algorithms based on the established chip solutions of the OEMs, but there are still large gaps in this part.
No matter whether the real front loading products can land or not, the development of domestic fatigue driving early warning system is inevitable. But what can really stand the test of the market and finally survive is the products with excellent technology.
