Gentex's booth in the west building of LVCC

　Gentex, which supplies parts such as rearview mirrors and electronic equipment to automobile manufacturers, The company exhibited its latest products at CES 2022 held in Las Vegas, Nevada, USA from January 3rd to January 7th.

　Gentex exhibited a system that monitors the driver and the cabin called the "Driver & Cabin Monitoring System". Driver monitoring is a system used for automated driving (or ADAS) of level 2+ or higher, and monitors whether the driver is in a state where the driver can be replaced at any time during automated driving, etc., and determined that it cannot be operated safely depending on the system. In such a case, the vehicle is safely stopped on the side of the road or the like.

　The cabin monitoring system monitors whether the safety of passengers is ensured in Level 5 automated driving vehicles, such as robot taxis, and also monitors whether children in the backseat of passenger cars are safe. system.

　Gentex also exhibited a rearview mirror integrated monitor solution called FDM (Full Display Mirror). The FDM integrated drive recorder, which is showing signs of popularity in Japan, and the selfie function with the camera attached to the rearview mirror were introduced.

Gentex's "Driver & Cabin Monitoring System"

At the CES Gentex booth, In addition to exhibiting a vehicle that uses parts supplied by the company on an OEM basis, a concept model that the company calls a "driver and cabin monitoring system" was exhibited.

　The driver & cabin monitoring system is, in short, a system that monitors the driver and passengers. In particular, driver monitoring is attracting attention and has become an important system for building automated driving systems of Level 2+ and above. This is because, for example, in level 4 autonomous driving, even if control is handed over to the car and the car is driving, if the car's system determines that it is difficult to continue driving (for example, the camera-based Autonomous driving system, but the fog is falling and you can't see the front), control is handed over from the car to the driver. For example, if the driver was sound asleep at that time because it was Level 4 automated driving, no matter how much the car handed over the control, it would not be possible unless the driver was awake. In such a case, the vehicle monitors the driver, recognizes that the driver is not responding, such as sleeping, and takes measures such as automatically stopping the vehicle if it determines that control cannot be handed over. In order to build such a system, driver monitoring is considered to be important in the future, and each company is putting effort into its development.

Driver monitoring can determine the state of the driver as well as what the driver has. Now we recognize that we have a smartphone. If we eat a potato, we can identify a potato

　Gentex exhibited this driver monitoring system, but at the same time it also has a cabin monitoring function. . A camera installed in front of the mirror captures the movements of the driver and passenger through image recognition, and a computer follows the detected feature points to determine the driver's movements. For example, if the driver's eyes are closed all the time, the system detects the amount of time the eyes are closed and determines that the driver is sleeping. Object recognition is also possible, and if the driver has a mobile phone, it can detect the mobile phone, and if he is eating potatoes, it can detect the potato.

It also has a "depth sensor" that can detect depth, so you can check the movement of a child in the back seat

. If it detects that the child has gotten off the child seat, it can alert the driver.

In addition, Gentex introduced a rearview mirror integrated monitor solution called FDM (Full Display Mirror). The major feature of FDM is that it can be used as a normal rearview mirror when nothing is being projected, but it can also be used as a monitor. Recently, it is showing signs of popularity in Japan, and there are an increasing number of cases where it is a genuine option that allows the image of the rear camera to be displayed on the rearview mirror, and that it is installed as a standard function in new cars from the beginning. Also, in the aftermarket, there are products that can be attached to the rearview mirror later, and recently, the number of FDMs with integrated drive recorders is increasing.

An FDM that outputs the image of a general back camera, and recently it is also available as an option for vehicles in the popular price range

, Selfie FDM, etc., which allows passengers to easily take selfies. Selfie FDM is a product that responds to the needs of East Asia (especially China), where people want to participate and take selfies easily, as it is possible to check the captured video with a smartphone. Putting aside the tsukkomi that it is okay to take selfies with a smartphone camera, the ease of taking pictures only with FDM is likely to be an appealing point.

Images shot with the Selfie Cam FDM can be viewed using a smartphone app

　In addition, a reference exhibit of a solution for detecting odors inside the car was also held. It is a unique product from an Israeli company acquired by the company that can detect odor-causing chemicals to detect if there is currently an odor in the cabin. For example, in a level 5 robotaxi that is operated without a human on board, if a passenger turns over a meal brought in, and is left unattended and gets off, the following situations will occur: Passengers will suffer. In such a case, if such a sensor were to be used, the robotaxi would be able to decide on its own whether it needed to be cleaned and go to maintenance.
