Lexus Annouces Innovative Safety Technology For The New LS 600 H Model

Toyota has come up with innovative new technology for Lexus with the intention of reducing the possibility of automotive accidents caused by motorists’ inattention to the road. The new Lexus LS 600h will feature the latest in pre-crash safety technology using a system that is able to keep watch over the driver to monitor his/her concentration levels. The Lexus LS 600h goes on sale next month.

Lexus has introduced an intelligent new driver safety system using 6 cameras that monitor the driver’s face as he/she operates the car. If there’s an obstacle in the path while the driver’s head is facing the wrong direction, this ingenious technology will activate a warning signal and then initiate safety measures on its own. The system also incorporates active headrest safety features designed to minimize injury in the event of a rear-end collision.

The world’s first innovative technology that provides for the Driver Monitoring System is one element of the advanced Pre-Crash Safety (PCS) system, which brings together a series of features that can recognize a potentially dangerous traffic/road situation and assist the motorist to take action to reduce the risk of a collision. If there is an impact, the system takes action to try to minimize the impact to the driver.

An algorithm map is utilized to measure the position of the driver’s facial features and monitors movement of the driver’s head, a CCD (charge-coupled device) camera is mounted on top of the steering column with 6 infrared LEDs to enable the system to work accurately both day and night.

When the ignition is turned over the system automatically plots the position of the driver’s facial features, eyes, nose, and mouth, and measures the width and center line of the face. If the driver’s head is turned away from the road at an angle of more than 15 degrees when the vehicle is moving and an obstacle is detected ahead, the system automatically activates the Pre-Crash warning signal and applies the brakes to warn of the danger.

If the initial warning precautions fail to prompt the correct action from the driver, the PCS engages emergency braking preparation and pre-tensioning of the front seatbelts.

Provided the driver’s face is in the clear sight-line of the camera, it will function accurately, regardless of the driver’s seat position. The system will even work properly when sunglasses are worn by the driver.

The safety technology in the Lexus LS is also integrated in the rear of the car with its Rear Pre-Crash Safety System. A rear-mounted miniature camera constantly monitors the area around the back of the car.

If a collision is unavoidable, the system activates the front seat Pre-Crash Intelligent Headrests which will move forward and upward to cushion the driver's head in anticipation of an impact, greatly reducing the risk of whiplash injury. The headrests are fitted with a sensor that measures the distance between the passenger’s head and the headrest itself, so there is no need for manual adjustment.

According to Dave Nordstrom, VP of marketing from Lexus: “In our latest television spot, we are inviting consumers into our state-of-the-art testing facility for a behind-the-scenes look at the Lexus driving simulator to see this revolutionary machine in action.” Nordstrom also stated: “It’s a real-life example of our innovation and dedication to bringing customers the future first.”
