Vehicle i.e. car, has bumper unit with sensor system designed as T-shaped hose, and pressure sensor arranged in hose aperture for acquisition of pressure change in inner space of hose caused by collision of bumper unit

摘要

The vehicle has a bumper unit (1) with a sensor system (2) for detecting collision of the bumper unit with a pedestrian, an animal or an obstruction i.e. bollard. The sensor system is designed as a T-shaped hose (2.1) with hose apertures (O1-O3). One of the hose apertures is arranged perpendicular to the longitudinal extension of the hose and provided with a pressure sensor (2.2) that is utilized for acquisition of pressure change in an inner space (2.1.3) of the hose, where the pressure change is caused by the collision. The other hose apertures are closed.
