Maneuvering aid and method for aiding drivers of vehicles or vehicle combinations comprising articulated vehicle elements
First Claim
1. A device for aiding drivers when maneuvering a vehicle or vehicle combination (1), where this vehicle consists of a plurality of vehicle elements (2, 3) that are articulated relative to one another, comprising:
- a camera (9) for sensing image data from the rear environment of the vehicle (1),one or a plurality of sensors for sensing the arrangement condition of the vehicle and/or the vehicle elements,a processor module which is connected to the camera (9) and to the sensor(s), wherein this processor module consists of at least one unit for image data processing, and at least one memory containing the measurements of the geometry, especially the circumferential geometry, of the vehicle (1), anda display unit (10) for the display of image data processed in the processor module,wherein the processor module comprises a determination module for determining a rectifiable condition of the vehicle for an updated position and/or for at least one predicted position of the vehicle, wherein the rectifiable condition of the vehicle is defined as a condition from which the vehicle can be aligned in a straight manner within a predetermined driving path preferably of less than four, three or two vehicle lengths.

Abstract
When maneuvering a vehicle, due to the seated position of the driver, the problem arises that a large portion of the space to the rear of the vehicle to be observed is hidden by the vehicle body itself. Therefore, the vehicle driver is presented with a display of a camera image of the space to the rear of the vehicle with a perspective overlay of the driving path and/or the towing path of the vehicle (1). Said driver support system is configured such that it is also suitable for guiding a vehicle or vehicle combination (1) in which the trailer comprises a plurality of vehicle elements (2, 3) that are bendable relative to one another. In order to detect the steering angle (7) of at least one steerable axis (6) of the vehicle (1), and in order to determine the bending angle (5) between at least two vehicle elements (2, 3) bendable relative to one another, sensors are provided. Using the data regarding the steering and bending angles (5, 7) and taking into account at least the geometry of the vehicle (1), the future driving path of the vehicle (1) is predicted in the processor module for the limits of the driving path and/or towing path and is superimposed on the image data captured by the camera. The image data thus processed is then displayed to the driver of the vehicle (1) on a display as a maneuvering aid.
