With the new SUBARU Outback (driving report) SUBARU is also presenting its Eyesight assistance system on the German market at the same time.
This is how the Eyesight system from SUBARU works
The system is based on a stereo camera and has been used in other markets since 2008. With the 2015 model year of the new Subaru Outback, the Japanese manufacturer is now bringing its Eyesight to Germany. However, some details have been revised. The cameras are now looking to 40% more in width and just as much further forward than before. The two cameras are the heart of the system and sit on the top window frame near the inside mirror.
Unlike in the automotive industry, Subaru is open-minded about the technology and even reveals who the supplier of the system is. The cameras are supplied by Hitachi, for example. The control systems were then developed by Fuji Heavy Industries, the parent company of Subaru.
Test - Subaru eyesight system
The Press appointment for the new Subaru Outback then not only gave an impression of the new Outback, but also enabled a first “dry test” of the Eyesight system. Very courageous Japanese gave the Outback test car a GoPro and captured the attempt on film:
EyeSight features include a predictive Brake Assist
(Pre-Collision Braking Control), an adaptive speed and distance control
(Adaptive Cruise Control), a Lane Departure Warning
Lane Sway Warning Assistant, a pre-collision throttle
Management) as well as a so-called “Lead Vehicle Start Alert”, which notifies the driver at a traffic light or in a traffic jam when the vehicle in front of him starts. The stereo cameras used for the system are located inside the car. They are installed as integrated units on the right and left side of the rearview mirror. The ability to identify objects achieved in this way is similar in complexity to that of the human eye.
Difference between "lane guidance assistant" and "lane departure warning system"
The two assistance systems sound similar and also have comparable tasks. While the Lane Keeping Assist is supposed to prevent you from leaving your lane by being annoying, the “Lane Sway Warning” takes on the role of a drowsiness warning.
The Lane Keeping Assist is currently still implemented as a passive assistant. He warns, but does not intervene. Although the Subaru Outback has electric power steering, the implementation of an active “driving aid” that counteracts unintentional driving over a lane by steering force influence or by “counter-steering” has currently been saved. However, in discussions with Japanese technicians and developers, an agreement was reached that this system would come. The market just has to demand it. Now one can say that there are drivers who do not like it when the car intervenes in the steering using an assistant. Yes, that may be true, but the customer should make the decision and if the system is on board, then you can always switch it off.
Personally, I find the pure beeping not sufficient. During the test drives on country roads in Slovenia, the impression emerged that the system would either beep too often - or too late. After the first admittedly rather short test drive, I wasn't really convinced yet.
Lane Sway Warning however, could be a real help. Many drivers are unaware of the fact that they are getting tired. If attention drops, it is a gradual process. But some people know the result. You no longer drive concentrated and a kind of serpentine line within your own lane. Hardly noticeable for yourself - the lane control assistant should warn in this situation. This function has not yet been tested.
Pre-Collision Braking- worked well. As you can see in the video above. Also the work of the adaptive tempomat is good. This accelerates the vehicle already when starting the overtaking process, if previously a higher speed was set by cruise control.
Eyesight - a right, an important step
There are still said to be drivers who want the leather reins of the driver's seat back and reject assistance systems. This is nonsense, of course, because no one is infallible. And anyone who drives a 1.5 ton object at 200 km / h on the autobahn shouldn't be averse to having a “good friend” by their side. How do you always say? Four eyes see more than two. The two cameras from Eyesight are therefore the right step. Even though there is still potential for optimization.
