Tube sensor: how the front contact becomes measurable

Useful to know

Bosch describes a system with an elastic silicone tube filled with air in the front of the car. The change of pressure is reported by sensors at deformation. The information can trigger protective mechanisms such as an active bonnet in a suitably equipped vehicle. [1]

It's a contact recognition system, not a camera that sees the pedestrian in advance. The two features may be involved in a wider protection, but work with different information.

It does not follow that every car with a similar front shape has this technology. Availability and performance are checked according to the specific model. When repairing the front, the hidden components deserve attention alongside the visible bumper. Externally restored panel is not proof that all connected security systems are checked. The text does not contain pressure or impact testing procedures.
