Lexus ES digital mirror, which became a big topic due to advanced appearance and aerodynamic performance.However, the number of applicants is very small, including other companies.
It was only after the Lexus ES was equipped with the Lexus ES in 2018 that the door mirror (once fender mirror), which has been used to check the backwards of the car forever, to the camera image. [Image] After the screen inside the door of the "e-tron", it is equipped with electric vehicles (EVs) such as Honda E and Audi e-Tron. It was hoped to make the rear confirmation more reliable, and in fact, there was an advantage that the ES test drive could clearly confirm parallel vehicles at a wide angle compared to mirror door mirrors. In addition, the ES also has a function of scaling and reducing the screen, and also includes a device to ensure that the part you want to check more reliably. On the other hand, the screen installed near the lower end of the front pillar is a part of the field of view that the image is always shown because the image is clear, even though it is in a position that is easy to follow. At that time, passing by an oncoming vehicle, the back of the oncoming vehicle that ran away is clearly reflected on the screen, so when you capture it at the end of your gaze, is the following vehicle running right behind! Sometimes it causes the illusion.
Although it looks clearer than the naked eye, it is too clear, so it takes time to focus on the perspective and when the viewpoint is transferred.It is costly, so it seems that it is still acceptable.
In addition, it is difficult to grasp the speed sensation of vehicles approaching from behind. Therefore, there is a method of indicating the standard on the screen with a line as a help to the sense of distance from the subsequent vehicle, but it may be difficult to determine the line depending on the status of the video, such as the color and size of the subsequent vehicle. On top of that, when it comes to presbyopia, it takes time to focus on the perspective, and it is difficult to see short distances in the first place, so it is time to check backwards with the video captured by the camera, including the room mirror. Sometimes it is necessary. When using a mirror, it recognizes the giant statue of the mirror surface, so you can handle presbyopia. On the other hand, camera images cannot recognize images unless they focus on the screen. People who use it as their car also hear that they will eventually get used to it. Nevertheless, in places where the joining of the expressway is three -dimensional instead of a plane, it is not possible to confirm the situation on the screen until the camera catches the back, and it seems that the conventional method using a mirror may be safer. Regarding the above points, E-Tron has a screen attached to the door instead of the lower end of the pillar, and can eliminate excess information while driving. If you move your eyes to the screen as before, you will be able to see the reality outside the side window at the same time, so you can reduce the discomfort that it is a camera -type side mirror, and check the screen and reality at the same time. There is consideration. It is a function that has only been three years since the appearance of ES, and it will be quick to conclude which method is correct. By proceeding with multifaceted verification both physically and mentally, such as how to use the driver's eye movements, how to use eye functions, and the psychology of driving people, it is possible that a more easy -to -use camera -type side mirror will be born. At the same time, we hope that the development will be useful for information management and safe driving around the car for autonomous driving.
