AI Technical Summary
Technical Problem
Existing vehicle sensors are not robust enough to reliably detect immersion in water, which is crucial for ensuring occupants can safely exit the vehicle during submergence events.
Method used
A sensor assembly with a flexible and deformable volume connected to a pressure sensor, where water ingress increases pressure within the volume, allowing for accurate pressure measurements to determine immersion depth and presence of water.
Benefits of technology
Provides reliable and robust detection of vehicle immersion, enabling timely actions to facilitate occupant egress, such as door opening and window operation, by utilizing pressure changes induced by water ingress.

Abstract
A sensor assembly (1) for detecting immersion of a vehicle (100) in water is disclosed. A structural element (10) of the vehicle (100) is used to hold the sensor assembly (1). At least the flexible and deformable volume (7) must be under water level so that an immersion in water can be detected. To measure a pressure increase the flexible and deformable volume (7) need to be in fluid communication with the least one sensor housing (2, 3).
