Mitsubishi Electric, the concept car "EMIRAI XS DRIVE" exhibited at "CES2022", etc. Open

　On December 20, Mitsubishi Electric developed an EMIRAI XS DRIVE, a concept car that is equipped with headlight distribution control technology in cooperation with the crew monitoring technology that detects driver's physical condition and ADAS (advanced driving support system) devices.It announced that a concept car will be exhibited at "CES2022" (January 5-8, 2022) held in Las Vegas in the United States.

Crew monitoring by near -infrared camera and radio wave sensor

The "Emirai XS Drive" shows the facial information of the driver imaged by the near -infrared camera installed in the car, as well as the expression and various biological information (pulse rate and breathing (pulse rate / breathing) that endure drowsiness.By analyzing the number, etc., the driver's awakening degree of awakening and sudden changes in physical condition are detected.The pulse measurement technology using a near -infrared camera is (Driver Monitoring System.: In addition to the high -precision face tracking technology of the driver monitoring system), the image processing technology that captures the brightness of the skin due to the pulse and the external light change, making it stable and high accurate in the inside of the vehicle environment.Measured.

　Combining these biometric information, estimating the inner state of a driver that is difficult to understand at a glance, detecting a low awakening degree and sudden changes in physical condition, it will be proposed for a break or automatically stops the vehicle on the shoulder in an emergency., Contribute to the prevention of accidents.

　In addition, by combining near -infrared cameras and radio wave sensors, the presence or absence of crews and physique are detected, and only infants are left behind in the car.

　The near -infrared camera determines the crew's physique with high accuracy by detecting the position of the crew's face and the skeleton of the upper body.The radio wave sensor can detect infants wrapped in blankets, which are the blind spots of near -infrared cameras, and infants hidden under the seat feet, by using signal processing of radio waves.The sensor fusion processing that combines this near -infrared camera and a radio wave sensor will achieve a higher accuracy of infant detection.

Headlight light distribution control using information inside and outside the car

　In Emirai XS Drive, HDL (High-Definition Locator).: By linking with high -precision locator), the direction of travel is always brightly irradiated according to the curve shape and gradient information of the road.In addition, in cooperation with DMS, brightly irradiates the direction that the driver focused on.In addition, the spotlight is irradiated in a dangerous direction that the driver is not aware of, and it encourages attention.

　The driver intuitively does not look forward to the litness display on the road and the warning sound output by the 3D sound image control, which is detected by a camera and a sensor for the outside vehicle, such as a camera and a millimeter wave radar.It can be recognized.

　In cooperation with various ADAS devices, the driver wants to see the direction of the driver and the dangerous direction that is not aware of it with headlights, eliminating the anxiety of drivers during nighttime driving and supporting safe and secure driving.。
