Danger warning system for drivers

On 6-9, Lexus announced that it has manufactured a new warning system for drivers with smart features and fully active. The system uses 6 cameras to manage the driver's face. If there is an obstacle on the way that the driver turns the other direction unnoticed, the vehicle will automatically stop.

The system also incorporates a seat cushion for each passenger to ensure a minimized hazard if there is a collision from the side or behind the vehicle. Lexus LS 600h cars launched next month will be installed this system.

When the car is started, the system automatically determines the position of the driver's face features such as eyes, nose and mouth; At the same time measure the width of some features as well as determine the centerline of the face. When the vehicle is moving, if the driver's head rotates at a 15-degree angle to the direction of the vehicle's movement and has an obstacle in front, the system will automatically activate the PCS alarm and will act. to win the car to warn the danger.

If these alarm signals do not work for the driver, the PCS system will win and tighten the seatbelt of the front occupant.

Before mass production, the system was tested with 100 drivers traveling 96,000 km long. The results show that facial features are clearly and accurately identified. Even when the driver wears sunglasses, the system can detect the movement of the face.

Besides monitoring the driver's face and the road ahead, the Lexus LS also has a hazard warning function on the side. Accordingly, the camera system on the side of the vehicle will monitor continuously around the rear of the vehicle. If a possible collision is detected, the chair backrest will automatically move up or down to form a cushion for the passenger, preventing head injury when an accident occurs.

In addition to the Lexus LS 600h, the system will also be mounted on the LS 600h L and LS 460 cars that will ship this year.

This system uses positioning algorithms of driver face features to monitor head movement.A CCD-based camera (charge-coupled device) is mounted on the top of the steering wheel with 6 internal infrared cameras allowing the system to work correctly both day and night.(Photo: TTO)
