Abstract
A front section of a motor vehicle includes an engine hood and a chassis. Support parts of the chassis are arranged in a receiving space of the front section body, at least partly below the engine hood. A water-fillable multi-chamber pad is arranged at least in a first partial region of the receiving space.
Claims15
A front section of a motor vehicle, comprising:
- a front section body which has a front hood;
- a chassis having structural parts disposed in a receptacle space of the front section body so as to be at least in part under the front hood;
- a multi-chamber pad which is fillable with sufficient water to wash all sensors used in a fully automated driving mode of the motor vehicle, the multi-chamber pad being disposed at least in a first sub-region of the receptacle space;
- and
- a branching water line system fluidically connected to the at least one multi-chamber pad, the branching water line system being disposed in the first sub-region, wherein
- at least one throttle is provided between some or all chambers of the multi-chamber pad,
- the at least one throttle retains water, and
- only those chambers of the multi-chamber pad that are disposed in a central region are fluidically connected to the branching system.

A motor vehicle, comprising:
- a body comprising a front section body, adjacent thereto a passenger cabin, and adjacent to the passenger cabin a rear section body;
- at least one multi-chamber pad disposed in at least one receptacle space of the front section body, of the passenger cabin and/or of the rear section body;
- and
- a branching water line system fluidically connected to the at least one multi-chamber pad, the branching water line system being disposed in a first sub-region of the receptacle space, wherein
- the at least one multi-chamber pad is configured to hold water in an amount that is sufficient to wash all sensors used in a fully automated driving mode of the motor vehicle,
- at least one throttle is provided between some or all chambers of the multi-chamber pad,
- the at least one throttle retains water, and
- only those chambers of the multi-chamber pad that are disposed in a central region are fluidically connected to the branching system.
5 more elements
A branching water line system of a motor vehicle, comprising:
- at least one main line;
- at least one branch line which is fluidically connected to the main line;
- a filling device;
- and
- a branching water line system fluidically connected to the at least one multi-chamber pad, the branching water line system being disposed in a first sub-region of the receptacle space, wherein
- the branching system is comprised of an inflatable 3D-printed material,
- the main line and/or the at least one branch line is fluidically connected to at least one multi-chamber pad,
- the at least one multi-chamber pad is configured to hold water in an amount that is sufficient to wash all sensors used in a fully automated driving mode of the motor vehicle, and
- only those chambers of the multi-chamber pad that are disposed in a central region are fluidically connected to the branching system.
