When it comes to making automobiles, there is a heavy emphasis placed on the designers and engineers of these cars to make them safer in the event that a crash takes place. Until recently, though, this focus on safety has involved only the passengers inside of a car that might get hit – there were not design features to address the safety of others. But recent developments have changed all that with new pedestrian detection technologies making their appearances in several modern American vehicles.
Pedestrian detection works in a similar manner to systems like lane departure warnings and front impact alerts. A series of sensors are placed on the outside of a car, truck, or SUV to monitor the surroundings of a vehicle as it operates. However, unlike similar systems, a pedestrian detection device is designed to monitor slow moving, more subtle movements indicative of a person who is walking. Some manufacturers are using radar as part of their detection systems, some are using cameras, and many are using a combination of technologies.
If a pedestrian is detected in the pathway of an oncoming car that is equipped with this technology, a driver will receive either a visual symbol on the car’s dashboard or will hear an audible warning. In some instances, the car may begin to brake automatically.
