BMW’s latest patent filing with the European Patent Office outlines an innovative system designed to enhance post-accident safety. This advanced mechanism integrates precise sensors and actuators to detect a collision and, once the vehicle has come to a complete stop, automatically opens a window. This feature is engineered to maintain occupant safety during the accident while allowing emergency services seamless access to the interior afterward, significantly improving rescue efficiency.
An Additional Safety System
This system does not replace any existing safety equipment, but acts as an additional process that only activates after an accident. Most modern cars already have several systems that are automatically triggered when an accident is sensed, some of which include:
- Activation of the hazard warning lights
- Disconnection of the high-voltage battery in EVs
- Notification of emergency services
- Post-collision braking
- Closing of the sunroof and windows
After The Accident
The last point above – the closing of the sunroof and windows while an accident is in progress – is important to provide maximum protection for occupants and to contain them within the vehicle. However, after the accident is over, closed windows hinder access to the vehicle and require emergency service to break them to provide assistance to the vehicle’s occupants. BMW’s system has electronic controls and sensors that detect the accident and then opens a window after it has happened.
Our Take
The patent does not indicate which windows are opened, and whether more than one window can be opened, although that should be easy to achieve by programming the software. It also doesn’t state whether there are conditions attached and whether the system can take any other variable into account, like the weather. For example, in freezing temperatures, it might not be advisable to open the window. If the system can be programmed in such a way to take such variables into account, it can be a worthwhile addition to any car’s safety arsenal.
