Introduction - The Road to Saving More Lives Passive safety products, such as airbags and seatbelts, are there to help protect you from injury if a crash is unavoidable. More than a million human beings owe their life to them. PROTECTION AUTONOMOUS DRIVING The major advancement from Active Safety products is to reduce the crash severity and avoid the crash altogether by warning the driver or automatically braking the car. PREVENTION In the future, self driving cars will ultimately provide the third level of automotive safety, significantly reducing the element of human error. Allowing the car to act automatically is crucial when moving towards our vision of saving 150,000 lives per year. AUTOMATION ALV-/v1.03 2012/General Presentation 2012 Page 6
Active Safety Sensors Radar Detects vehicles and objects Measures distances Is not sensitive to light conditions Infrared Sensing Does not need visible light Classifies pedestrians and animals Vision Detects visible shapes, markings, objects Reads lane markings, light sources, traffic signs Classifies objects as vehicles and pedestrians ALV-/v1.03 2012/General Presentation 2012 Page 7
Active Safety Functions Autonomous Emergency Braking alerts the driver, tightens the active seatbelt, puts the brakes in an alert mode and applies the brakes autonomously. (radar or vision) Traffic Sign Recognition a symbol is displayed in the instrument cluster or on the Head-up Display showing the current speed limit or other important road signs. (vision) High/Low Beam Assist automatically switches between high and low beams. (vision) Blind Spot Detection alerts the driver by lighting a warning indicator on the appropriate side. Road/Lane Departure Assist alerts the driver with acoustical or haptic warnings and/or a symbol on the head-up display. Queue Assist maintains a set speed/distance to a vehicle ahead down to a standstill. (radar) (vision) (radar or vision) Pedestrian Detection/Warning warns the driver or even autonomously brakes the vehicle. Adaptive Cruise Control maintains a set speed/distance to a vehicle ahead. Cross-Traffic Assist acoustic alert. (vision) (radar or vision) (radar) ALV-/v1.03 2012/General Presentation 2012 Page 8
