Process and device for avoiding collision while opening vehicle doors
First Claim
1. A process for avoidance of collision when opening doors of a vehicle, comprising the following steps:
- determining a projected path of movement (6) of the vehicle (4),detecting objects (1) in the near or far environment about the vehicle (4) using environment sensors,determining the projected movement paths (2) of the detected objects (1),determining a probability space (7) for the pivot area (5) of the vehicle doors and a probability space (3) for each detected object (1),comparing the probability space (7) of the pivot areas (5) of the vehicle doors with the probability spaces (3) of the objects (1) so that a possible overlapping can be detected, andproducing a reaction signal indicating a danger of collision when an overlapping is recognized.

Abstract
The opening of vehicle doors often leads to collisions with stationary obstacles that are not visible to the occupants or with moving obstacles that approach the vehicle without being noticed. Thus to avoid collisions when vehicle doors are opened, the aim of the invention is to take any modifications to the environmental situation of the vehicle as a result of a movement of the vehicle and the detected objects into consideration. This allows a collision of the vehicle doors with the objects to be reliably avoided. To achieve this, in a first step the probable trajectory of a vehicle is determined. In an additional step, the objects in the vicinity of the vehicle are detected and probable trajectories of said detected objects are determined. Respective probability ranges are then defined both for the vehicle and the pivoting zone of the vehicle doors and for the detected objects. The probability ranges of the pivoting zones of the vehicle doors are respectively compared with the individual probability ranges of the objects, in order to determine whether they overlap. If an overlap is identified, a response; signal that indicates the risk of a collision is generated.

10. A device for avoiding collisions during opening of vehicle doors, including a collision monitoring unit (9) including
an evaluation unit (10a), which recognizes objects (1) in the environment of a vehicle (4) from sensor data from environment sensors and determines projected movement paths (2) for the detected objects (1) and which determines the projected movement path (6) of the vehicle (4) from sensor data from the sensors, and a micro-processor (10b), which is programmed to determine a probability space (7) for the vehicle (4) and probability paths (3) for the detected objects (1) and to recognize an overlapping of a probability space (7) and a probability path (3), whereupon the micro-processor (10b) emits a reaction signal indicating danger of collision to a warning means or a control unit (13) in the case that an overlapping has been determined.
