Problems solved by technology

However, the algorithms for converting the object data into information representing the three-dimensional space are complex and require high computational efficiency, so that a delay in the reaction of the protective device and thus a delay in interrupting the movement of the luggage compartment lid can result.
In addition, measurement inaccuracies can lead to relatively inaccurate distance determinations. This must be taken into account especially in unfavorable lighting conditions, e.g. in underground garages, where the resolution or the image data provided are imprecise
Therefore the risk of an undetected collision cannot be ruled out

Embodiment Construction

[0023] figure 1 A device 1 according to the invention is shown as part of a motor vehicle 2 parked in a parking garage 3 whose ceiling 4 is only slightly higher than the roof 5 of the motor vehicle 2 .

[0024] A hood, that is to say the trunk lid 6 of the motor vehicle 2 , can carry out a tilting movement 7 in the tilting space 8 automatically, that is to say driven by a gas spring or a servomotor, for example. In the illustrated situation, the luggage compartment lid 6 runs the risk of hitting the ceiling 4 of the parking garage 3 . The ceiling 4 of the parking garage 3 is therefore an object or obstacle 9 that may collide with the luggage compartment lid 6 .

[0025] A lighting device 10 in the form of a taillight 11 emits a beam of light 12 in the pivoting space 8 . This beam of light forms a light spot on the ceiling 4, which reflects at least part of the emitted light. This reflected light 13 is directed at least partially in the direction of a detection device 14 whi...

Abstract

A device is provided for preventing a collision between a pivoting element of a vehicle, with an obstacle located in its pivoting area, with a control unit which controls the pivoting movement of the vehicle pivoting element and with a lighting device which is coupled to the pivoting movement and emits light into the pivoting area. Depending on the reflection of the emitted light on the obstacle the control units intervenes in the pivoting movement.

Description

technical field [0001] The invention relates to a device which is used exclusively or in addition to other functions for avoiding a collision of a pivotable cover of a motor vehicle, for example a roof or a door, with objects or obstacles situated in the pivoting space of the vehicle cover. Background technique [0002] A device for crash protection of a motor vehicle's boot lid is known from the published international patent application WO 2009 / 092168 A1, which also describes a driver assistance system for protecting a motor vehicle's boot lid. Such devices include an imaging device that detects one or more objects located around the deck lid. The data representing the detected objects is converted by an algorithm into information describing the three-dimensional surrounding space of the decklid. Using this information, the distance between the tailgate and surrounding objects can also be determined. If this distance is less than a preset value such that a collision betw...
