How can airbags tell the difference between a speed bump and an actual crash? Both can create sudden jolts and sharp changes in motion, so why doesn’t your airbag deploy every time you hit a rough patch of road? The answer lies in how your car’s safety system measures acceleration, direction, timing, and changes in velocity within just milliseconds. In this video, we’ll look at how airbag sensors work, what a “crash pulse” means, and how the system analyzes the pattern of an impact before deciding whether to deploy.
