Description

The following descriptions concern a driver assistance system for extending the user's field of vision in a motor vehicle, thereby improving driving comfort and increasing driving safety. Furthermore, the following descriptions concern a motor vehicle comprising the driver assistance system and a method for extending the user's field of vision in a motor vehicle. It is known that vehicle components such as the A-pillar, B-pillar, or C-pillar can obstruct the field of vision of vehicle occupants. Solutions that use camera systems to display the vehicle's surroundings via VR glasses are available, for example, from... DE 102016008231 A1 known. There is a constant need to improve driving comfort and safety for drivers of motor vehicles. Based on this situation, the task at hand is to propose a driver assistance system that expands the user's field of vision and increases driving safety. The present problem is solved by the features of the independent claim. Advantageous embodiments are specified in the dependent claims, the description, and the drawings. Where technically feasible, the teachings of the dependent claims can be combined arbitrarily with those of the main and dependent claims. In particular, the task is therefore solved by a driver assistance system for extending the user's field of vision in a motor vehicle, comprising: - at least one camera device for capturing the surroundings of the motor vehicle; - at least one user-portable display device for showing at least one field of view of at least one camera device and/or the user's field of view, wherein the display device has a plurality of viewing areas for showing the surroundings of the motor vehicle; - at least one gaze direction detector to determine the user's gaze direction; - a control unit connected to the at least one camera device, the display device and the gaze direction detector for selecting at least one camera device depending on the user's gaze direction and for generating at least one video image for each viewing area of the display device by means of at least one camera device, wherein the control unit is designed to transmit the at least one video image for each viewing area to the display device. By using a display device, a user's field of vision can be expanded by displaying video images from at least one camera. The display device features multiple viewing areas to provide the user with several views of the vehicle's surroundings, with at least one viewing area aligned with the user's line of sight. This allows vehicle components that obstruct the user's view to be hidden in real time and overlaid or replaced by the video images from the at least one camera. Expanding the driver's field of vision enables the driver to quickly and reliably identify hazardous situations while driving and to take timely countermeasures. This significantly improves driving safety. The following sections explain advantageous aspects and subsequently describe preferred modified embodiments. Explanations, particularly regarding advantages and definitions of features, are essentially descriptive and preferred, but not limiting, examples. If an explanation is limiting, this will be explicitly stated. It is preferred that the sequence of process steps can be varied, unless a specific sequence is technically required. However, the aforementioned sequence of process steps is particularly preferred. Where ordinal numbers, such as "first," "second," etc., are used, for example to designate a component, an element, a process step, or a process action, these ordinal numbers are solely for differentiation in the designation and do not indicate any dependencies or sequences. This means, in particular, that a device does not need to have a "first component" to have a "second component." A device can also have a "first component" and a "third component" without necessarily having a "second component." Multiple units with the same ordinal number are also possible, for example, multiple "first components." The driver assistance system comprises, in particular, a multitude of camera devices, which are at least partially mounted on the vehicle body, on the display device, and/or in the vehicle's interior. Each camera device has a field of view in which it captures the vehicle's surroundings. The camera devices are connected to the control unit via a data cable or wirelessly. The control unit is configured to receive image data from at least one camera device, depending on the user's viewing direction, and transmit it to the display device. The video images from a multitude of camera devices can, in particular, be arranged in an overlapping manner and transmitted by the control unit to the display device. This allows a continuous view or representation of the surroundings to be generated and projected within the display device. The display device has multiple viewing areas for showing the vehicle's surroundings, and the control unit is specifically designed to tran
