How ADAS and DMS Work for Commercial Vehicles
ADAS and DMS are getting more and more important for commerical vehicles now. Commercial vehicles have always been a low-key and small market share. As a production tool, commercial vehicles play a more important role in the transportation of means of production. At the same time, it also means longer driving journey, more difficult transportation task and higher driving risk. The risk takers include not only drivers, but also all road traffic participants.
It may be more intuitive to use a data to illustrate. According to the statistics of the World Health Organization, there are as many as 500000 traffic accidents in China every year, with an average annual death toll of more than 100000 people, ranking the first in the world for more than ten years in a row. Most of the major traffic accidents are in commercial vehicles. Take freight cars as an example, freight cars only account for about 15% of the total number of motor vehicles in China, but nearly half of the total number of deaths are caused by road traffic accidents.
In other words, it is urgent to solve the hidden danger of commercial vehicles.
On the other hand, today’s ADAS technology has been able to partially meet the needs of commercial vehicles for safety assurance. The state is also gradually aware of this, began to introduce relevant policies, and put forward specific requirements for the commercial vehicle industry in terms of safety.
For the manufacturers focusing on the research and development of commercial vehicle ADAS technology, this is undoubtedly a rare bonus and a prelude to the outbreak of the market. But at the same time, a large number of players from home and abroad have poured into this hot land, and the competition will reach an unprecedented level.
So, what kind of ADAS products can best meet the safety needs of the commercial vehicle market? How to make the cake of commercial vehicle ADAS market bigger and more points? Who is in charge of the ups and downs of the competing ADAS manufacturers?
Safety, the topic of commercial vehicle ADAS
According to a survey of heavy truck drivers, 73% of the accidents are caused by fatigue driving, followed by 41% of the accidents caused by eye occlusion, while 32% and 26% of the drivers are inexperienced and inattentive respectively. These factors lead to the main accidents of commercial vehicles, such as rear end collision and pedestrian rollover.
Today’s ADAS can greatly alleviate the security risks.
The so-called ADAS (Advanced Driver assistance systems), namely advanced driving assistance system, mainly includes fatigue driving warning system (DMS), lane departure warning system (LDW), forward collision warning system (FCW), blind area monitoring system (BSD), adaptive cruise system (ACC), automatic emergency braking (AEB), etc.
Although the functions of ADAS seem complicated, its core is not to control the car, but to give the car and driver the ability to predict the possibility of danger
In the process of vehicle driving, on-board sensors will real-time sense the environment inside and outside the vehicle and collect data to identify, detect and track static / dynamic objects, and then combine with navigation map data to carry out relevant system calculation and analysis, so as to warn drivers of possible dangerous conditions and help them take measures to avoid traffic accidents.
Adas has been able to bring safety benefits to commercial vehicles.
In 2018, more than 80 lives died in Shenzhen due to the problem of “death moon”. Aiming at this pain point, Ruiming technology, which is dedicated to the research and development of commercial vehicle security system, has built a pedestrian full-time warning system based on AI blind area.
Li Heng, CTO of Ruiming technology, said:
One more pair of tireless machine eyes to focus on road risk is meaningful.
Tong Lifeng, general manager of Mobileye Greater China region, also told xinzhijia that based on the verification of a total of 1.4 billion miles in the past three years, the anti-collision safety system jointly developed by Mobileye and sotorian has helped the fleet reduce the collision rate by 75% and the collision loss by 49%. No casualties have occurred.
On the basis of ensuring safety, ADAS can also bring some “added value” – from the perspective of afterloading market, the carrying of ADAS products can reduce the premium and operating cost of the fleet to a certain extent.
On the other hand, with the development of technology, ADAS products may have been unable to meet the needs of some OEMs. For example, DMS, blind area warning, emergency braking and other functions are now integrated into a whole scheme.
