Speaking of the Subaru brand, everyone is most impressed by it is the two terms of "horizontal confrontation" and "full-time four-wheel drive". However, with Subaru's models widely equipped with The Insight driver assistance system, it may make you look at Subaru's safety.
If you're hearing about EyeSight driver assistance systems for the first time, you'll think of the hottest concepts of autonomous driving and driverless driving today. However, unlike the "free" driver's hands pursued by unmanned driving, EyeSight acts as an auxiliary driver, and all its operations are still based on the driver's control. This time, Cheyun Research Institute conducted an in-depth evaluation of the Eyesight driver assistance system through the "CC-400A Intelligent Driving Evaluation System", so where are the advantages of Eyesight compared with other brands of driving assistance systems?
How does the Eyesight system work?
At present, many entry-level models have been equipped with adaptive cruise function. However, Subaru's EyeSight Driver Assistance System (now evolved to Appreciate Version 3.0) is very different from other common driver assistance hardware, relying solely on the binocular camera to achieve the same function. Two stereo cameras that approximate the human eye identify objects through color CCD imaging, which can accurately identify the distance, shape, and speed of movement of the target object. In addition to cars, it can also identify a variety of targets such as travelers, bicycles, and motorcycles. In addition, the Color Imaging Eclipse system can also identify the braking behavior of the car in front of it.
Therefore, the EyeSight driver assistance system can predict the risk of collision accidents in advance, reduce injuries, provide support for safe driving, and can also realize the auxiliary driving function of "avoiding accidents" or "reducing driving load" according to the vehicle situation. In its more blunt language, the system is like a driving school instructor in your car, which can not only give you some assessments, tips and warnings, but also interfere with your vehicle if necessary. Below, we will focus on sharing the driving experience that is directly related to the user.
During the vehicle's driving process, the Eyesight Driver Assistance System mainly provides ACC full-speed adaptive cruise and lane departure correction assist functions. Both the ACC and lane departure correction assist switches are easily found on the steering wheel, unlike some models I know of that require access to the multi-level menu on the central control screen to turn off lane departure correction.
One of the things that subaru's Agile driver assistance system does better is that when a vehicle with a similar speed is inserted from the side into the lane you are driving, the Eyesightt driver assistance system will display the vehicle on the instrument LCD screen and calculate the speed difference between the two vehicles, at this time, even if the distance between the two vehicles is significantly less than the set car follow-up distance, and the Agileightt driving assistance system judges that the driving speed of the car in front of it is faster, it will not even intervene in the power output. It is very good to ensure the smoothness of the cruising process.
Some other vehicles that use millimeter-wave radar adaptive cruise system have a limited angle of radar detection range installed in front of them, and for vehicles that are quite close to each other and suddenly insert into the front, the system will judge that the distance is too close, and automatically brake to avoid collisions and maintain a distance from the car, which will affect the comfort of the ride.
In addition, there is another detail that I like, the current car leaves the current lane, or a new vehicle comes in, the Eyesightt driver assistance system will gently beep, telling the user that it has changed a car to continue to follow the car.
In addition, EyeSight driver assistance systems work well in non-ideal conditions such as rain, night, and backlight, including identifying the car in front and lanes. Personally, I feel that the limits of the EyeSight driver assistance system are relatively high.
The Eyesight driver assistance system also has its shortcomings, that is, in the corners/ramps, it will always lose the front car and then suddenly accelerate, and the ability is still a little worse than we expected.
What does Subaru EyeSight bring to users?
Japanese car companies have always been technology-driven enterprises, such as Honda's Earth Dream Engine, Toyota's dual engine, Mazda's Chuangchi Blue Sky, and similarly, subaru also has a consistent "paranoia" on the road of assisted driving to ensure vehicle safety.
Many people think that driver assistance systems have been widely concerned by consumers in recent years with the improvement of driverless technology, and in fact, Subaru began to develop driver assistance systems with stereo cameras in the 1980s, and has made phased achievements.
In 1999, Subaru mass-produced a model equipped with the ADA system, which was the predecessor of the EyeSight system. In 2008, an anti-collision braking system was built through the monomer control of the stereoscopic camera, and the name was finally determined as "EyeSight Driver Assistance System". At present, the pre-collision function and basic performance of the EyeSight driver assistance system have been greatly improved.
Write at the end
Overall, as a driver assistance technology, EyeSight's driver assistance system does a really good job. But don't forget, like all other assisted drivers, EyeSight is not a substitute for human driving, so be sure to stay focused. What I want to say is that knowing the limits of a technology and understanding where it is good at, playing to its strengths and avoiding its weaknesses, is the right way to open.
