MOTORING: Automatic Braking System Now Reacts to People
Recent Gauteng Business News
Collision Warning with Full Auto Brake and Pedestrian Safety consists of a new dual-mode radar unit integrated into the car's grille, a camera behind the inside rear-view mirror and a central control unit. The radar and camera continuously monitor the road in front of the car. The radar's task is to detect objects and measure the distance to them. The camera's function is to determine what type of objects they are.
As before, the system is programmed to respond to cars in front that are at a standstill or moving in the same direction. Thanks to the state-of-the-art radar, which has a far wider field of vision than before, pedestrians about to step into the roadway can be detected early. What is more, the camera has better resolution than in the previous generation, allowing the system to monitor pedestrians' movement patterns.
"We've been working on this technology for ten years now. We have had test cars out on the roads for several years and we've driven in many different countries. Factors like traffic behaviour, road conditions and climate must be taken into account in the design of the final system. We can also use the information from these real-life traffic tests to conduct advanced computer simulations," says Thomas Broberg.
In an emergency situation, the driver first gets an audible warning together with a flashing light in the windscreen's head-up display. In order to prompt an immediate, intuitive reaction, the visual warning is designed to look like a brake light coming on. If the driver does not respond to the warning and the system assesses that a collision is imminent, the car's brakes are applied with full braking power.
Active brake deployment requires that the object is confirmed by both the radar and the camera. Thanks to state-of-the-art sensor technology, it is now possible to engage full braking power. It is among the very first systems in the world to offer full-braking protection for pedestrians. The system is built along the same principles as the human eye and, just like our own eyes, vision is impaired in the dark and in poor weather.
