Abstract

The multimedia system includes one or more cameras (1, 2, 3) and screens (4, 5, 6) to detect the vehicle occupants, and a control unit connected to the cameras and screens. by means of which the pictures received by the cameras are controllable to be shown on one or more of the screens. The first camera may be roof-mounted, with a detection angle covering all the rear seats.

Description

The The invention relates to a multimedia system for a vehicle.

While Driving in a vehicle is a visual contact between vehicle occupants Significantly limited on the front seats and rear seats. In particular, the driver and front passenger must follow their head Turn back to approach vehicle occupants in the back seats see. This affects the communication comfort between the vehicle occupants and complicates the observation, for example of children in the back seats by the driver and front passenger. If the driver turns his head back, as well the driving safety is impaired, as the driver his Look away from the traffic.

Out US 5808661 a communication system for an aircraft is known. The communication system includes, among other things, a camera for detecting a flight attendant and a plurality of screens at seats of the passengers on which video images recorded by the camera can be output.

Of the Invention is based on the object, a device for a vehicle to improve communication comfort and indicate the mutual perception of vehicle occupants.

The Object is achieved by an arrangement having dissolved, which has the features specified in claim 1.

advantageous Embodiments of the invention are the subject of the dependent claims.

The The invention provides a multimedia system for a vehicle one or more cameras arranged inside the vehicle for detection arranged by vehicle occupants and one or more in the vehicle interior Screens before. Furthermore, the multimedia system includes one with the or the cameras and at least one screen connected control unit, by means of which the output of images taken by the camera or cameras on the at least one screen is controllable.

The inventive multimedia system allows it, images, preferably video image sequences, of vehicle occupants on one or more screens. For example, you can Images of vehicle occupants in the back seats on a be displayed by the driver and front passenger's visible screen. As a result, the driver and passenger need while driving do not turn her head back to the vehicle occupants to see in the back seats. This improves the communication comfort between the vehicle occupants by a visualization of a conversation partner, facilitates, for example, the observation of children in the back seats and increases driving safety, as the driver rarely seduces is going to turn his head backwards.

Further Advantages, features and details of the invention are described below based on embodiments with reference to a drawing described. Showing:

1 a vehicle with cameras and screens arranged inside the vehicle.

1 shows a vehicle with a multimedia system according to the invention, the three cameras 1 to 3 and three screens 4 to 6 and includes a control unit, not shown.

This is a first camera 1 arranged in the vehicle interior to the roof of the vehicle approximately in the middle and integrated, for example, in a vehicle roof. The first camera 1 is to the back seating on a backseat 9 aligned with the vehicle and has a detection angle α, for example, 180 degrees, which is sufficient to detect all rear seats of the vehicle. This allows all passengers 12 . 13 in the back seat 9 from the first camera 1 be recorded.

A second camera 2 is arranged on a driver-side A-pillar of the vehicle and aligned to the driver's seat. It has a detection angle β which is sufficient for a driver 10 of the vehicle.

A third camera 3 is arranged on a passenger-side A-pillar of the vehicle and aligned to the passenger seat. It has a detection angle γ which is sufficient for a passenger 11 of the vehicle.

A first screen 4 is preferably located centrally on the dashboard of the vehicle or integrated into the dashboard, so that he from the driver 10 and the passenger 11 is visible.

The control unit is with the cameras 1 to 3 and the screens 4 to 6 connected. By means of the control unit are the cameras 1 to 3 and the screens 4 to 6 , preferably independently of one another, can be activated. Further, by means of the control unit, the output of the cameras 1 to 3 taken pictures on the screens 4 to 6 controllable.

Preferably, those of the first camera 1 taken pictures on the first screen 4 issued by the second camera 2 and / or from the third camera 3 taken pictures on the second screen 5 and / or on the third screen 6 ,

This can advantageously the driver 10 and the passenger 11 on the first screen 4 the vehicle occupants 12 and 13 see in the back seats, and the vehicle occupants 12 and 13 on the back seats can be on the second screen 5 and / or the third screen 6 the driver 10 and / or the passenger 11 see.

The cameras 1 to 3 are preferably video cameras, so that by means of the multimedia system video image sequences of one or more vehicle occupants 10 to 13 on one or more of the screens 4 to 6 are dispensable.

In an advantageous embodiment of the invention, the control unit can be connected to a navigation system in the vehicle, so that the image output on the screens 4 to 6 is controllable via the navigation system.

As a result, a separate control surface for the control unit on the dashboard is avoided. Furthermore, in this way the output of information supplied by the navigation system, for example via a driving route and / or traffic situation, on the second screen 5 and / or the third screen 6 be issued and so the vehicle occupants 12 . 13 be made available on the back seats.

In Another embodiment of the invention is the control unit additionally or alternatively with one or more mobile Communication and / or data processing devices connectable, for example a mobile phone and / or a portable computer. For this purpose points the control unit preferably one or more interfaces via which they are wired and / or wireless by means of electromagnetic Shafts with such devices is connectable.

suitable Interfaces include Bluetooth, infrared, USB and / or Firewire interfaces.

This can be done by the cameras 1 to 3 supplied image information is transmitted to a connected to the control unit communication or data processing device.
