TRW promotes advanced pedestrian detection system with automatic emergency braking

October 12, 2011 Hunsrück Test Center in Germany - TRW (Texas) Automotive Holdings (NYSE: TRW) demonstrated a full range of advanced cognitive or intelligence in a large test drive event in Wueschheim, Germany Security system. One of its highlights is the newly developed front-view pedestrian detection and accident mitigation system. It uses advanced signal processing algorithms to fuse video camera data and radar sensor data, and combines electronic stability control (ESC) to achieve automatic braking. Helps reduce the severity of pedestrian injuries.

Martin Thoone, vice president of electronic engineering at TRW, said: "The risk of serious injury or death is high when a pedestrian and vehicle collide. According to statistics, when the vehicle speed is 40 mph, the pedestrian crash rate is 85%. At 30 miles per hour, the mortality rate is 45%, and at a speed of 20 miles per hour, the mortality rate drops to 5%.The active pedestrian detection system allows the vehicle to decelerate automatically, reduce the collision speed, and even avoid collisions, which can significantly improve the survival of pedestrians. rate."

TRW's forward-looking pedestrian detection system fuses adjustable-level video camera sensor information with 24 GHz radar data. When the camera detects pedestrians in front of them, the system will use a sophisticated risk assessment algorithm to determine the collision probability after being confirmed by the radar to warn the driver and automatically activate the braking function to decelerate the vehicle and reduce the severity of the collision. The system is in line with TRW's production of radar-based emergency braking technology.

Mr. Thoone also pointed out: "In addition to detecting vehicles, lanes, and identifying traffic signs, adjustable-level cameras have the ability to detect and track pedestrians within 40 meters and can work under complex urban traffic conditions, such as detecting crowded sidewalks. Pedestrians or umbrellas in rainy weather. By adding radar and sensor fusion technology, system performance is improved and full braking at higher speeds is achieved."

This new pedestrian detection technology can be used in conjunction with TRW's pedestrian protection system. Sensors mounted on the front of the vehicle detect actual pedestrian collisions, activate active safety devices (such as car cover opening function to reduce collision damage), and improve collisions. Chinese pedestrian safety protection.

TRW expects to mass-produce a forward-looking pedestrian collision mitigation system with full braking capability in 2014.
