Description

Technical area

The invention relates to display devices for motor vehicles, in particular display devices for providing information to occupants of a motor vehicle.

State of the art

The cockpit of motor vehicles has a multiplicity of different display devices which inform a driver and the occupants of the motor vehicle about driving and vehicle conditions.

Some of the display devices relate to safety-related aspects, such as an indication of an opening state of vehicle doors and the like, so that the driver is informed of an improperly closed vehicle door.

In particular, when getting out of the vehicle there is a risk that the occupants inadvertently open a vehicle door too far and they hit against an obstacle, such as an object, a wall or a person, resulting in either damage to an object or the vehicle door or injury to the person.

From the publication DE 10 2005 023 002 A1 a door opening aid with a collision warning is known, in which with the audible and / or visual display means the motor vehicle driver feedback about the door opening process can be communicated. By appropriate warning signals can be communicated so that there is an obstacle in the swivel range of the vehicle door, so that the motor vehicle driver is already informed when operating a control element to open the vehicle door that the vehicle door will not be fully open.

Alternative approaches are for example from the publications DE 10 2008 023 786 A1 . DE 10 2004 020 426 A1 . DE 105 33 804 A1 and DE 298 11 689 U1 are known in which devices are described which inhibit the opening of a vehicle door, when there is a risk that the vehicle door abuts an obstacle.

The above approaches, however, have the disadvantage that before opening the vehicle door, the driver does not receive any indication as to how far the vehicle door can be safely opened without abutting the obstacle.

It is therefore an object of the present invention to provide a way that warns the driver of a motor vehicle in front of an obstacle and helps him continue to avoid that the vehicle door abuts the obstacle.

Disclosure of the invention

The obstacle 2 is located next to the motor vehicle 1 that it is when opening a corresponding vehicle door 3 of the vehicle 1 the possible opening angle of the relevant vehicle door 3 limited, leaving the vehicle door 3 to the obstacle 2 can trigger.

The vehicle door 3 is with a position detector 4 provided that can detect a distance to obstacles. The position detector 4 has to a detection area, which is substantially perpendicular to the path of the vehicle door 3 is aligned. The position detector 4 is preferably at an outer end E of the vehicle door 3 attached to monitor the entire swivel range, the vehicle door 3 when opening up to an open position in which the vehicle door is fully open, can sweep. Alternatively, the position detector 4 also at a different position on the motor vehicle 1 be arranged, as long as he the pivoting range of the vehicle door 3 to monitor obstacles.

Inside the motor vehicle 1 is a display device 5 provided to the occupant of the motor vehicle 1 in the form of an optical display provides an indication of how far his vehicle door 3 can be opened without hitting the obstacle 2 to initiate. This maximum opening angle can be presented to the occupant in various ways. The display device may, for. B. a screen display, such. As an LCD or TFT display, a 7-segment display and a simple lighting display include.

Further, a control unit 6 provided with the position detector 4 and the display device 5 is connected to when detecting the obstacle 2 in the swivel range of the vehicle door 3 the position of the obstacle 2 to detect and from this a maximum possible opening angle for the vehicle door 3 to investigate. The maximum possible opening angle can be, for example, when the vehicle door is closed 3 from the position of the obstacle 2 with respect to the pivot axis of the vehicle door 3 be determined in known manner with knowledge of the closed position of the vehicle door.

Furthermore, at one at the vehicle door 3 attached position detector 4 the control unit 6 the movement of the vehicle door 3 by changing the detected position of the stationary obstacle 2 monitor and determine a corresponding indication of the current opening angle.

To give the driver a sense of how far a partially opened vehicle door 3 can still be moved in the opening direction, can also during opening of the current (current) opening angle in a second display panel 52 are displayed.

Alternatively or additionally, the maximum opening angle can also be indicated by a display of a schematic plan view of a motor vehicle in a third display field 53 the display as an opened vehicle door, for example, dashed, are shown as it is in 2 by a first display element 54 is shown.

Furthermore, additionally the instantaneous opening angle of the illustrated vehicle door 3 on the third display 53 through a second display element 55 be represented, whose angle to the vehicle body shown the actual opening angle of the vehicle door 3 can correspond.

Instead of the angular degrees in the first and second display fields 51 . 52 can the maximum permissible opening angle of the vehicle door 3 or the current opening angle can also be specified in a unit other than angular degree.

Often there are vehicle doors 3 provided with several detent positions that the vehicle door 3 can hold in a certain opening angle and make up the vehicle door 3 can only be moved out by overcoming a certain resistance. Press or pull to open or close the vehicle door 3 the driver can open the vehicle door 3 move from a detent position to a next detent position. For this case, in addition to or instead of the angle indication in the first display field 51 also the number of detent positions around the vehicle door 3 can be opened maximally without abutting the obstacle, starting from the fully closed state of the vehicle door 3 in a fourth display field 56 are displayed. Also, in addition to or instead of the angle indication in the second display field 52 also the number of detent positions around the vehicle door 3 can still be opened without abutting the obstacle, starting from the currently achieved opening angle of the vehicle door 3 in a fifth display field 57 are displayed. For example, four locking positions between the fully closed state of the vehicle door 3 and the fully opened state of the vehicle door 3 provided, an indication of "3" in the fourth display field 56 indicate to the occupant that he can open the vehicle door - starting from the fully closed state of the vehicle door - up to the third detent position without any danger to the obstacle 2 to initiate. An indication of "2" in the fifth display field then indicates how many detent positions the occupant may still move the vehicle door in the direction of the open position.

It can be provided that the display device 5 is activated only when the vehicle is stationary and no obstacle detection while driving. As a result, a distraction or disturbance of the driver by momentary flashing a permissible maximum opening angle is avoided.

Furthermore, it can be provided that the display device 5 at standstill of the vehicle is activated only when the obstacle 2 in the swivel range of the vehicle door 3 has been recognized. Was not an obstacle 2 detected, the display panels can remain unlit, so that the occupant knows even without consciously looking at the display device that when opening the vehicle door is no risk of kicking.
