Description

Described are a method for displaying an environment of a motor vehicle, a computer program product and a motor vehicle.

Methods for displaying an environment of a motor vehicle, computer program products and motor vehicles of the type mentioned are known in the art. The top priority in road transport is safety. D. H. Avoidance of accidents. Modern motor vehicles can contribute to this in various ways, on the one hand passively, that is to say the protection of the occupants in the event of an accident by structural design of the motor vehicle, and on the other hand actively, i. Prevent or avoid dangerous situations.

It is known to monitor the environment of a motor vehicle by means of sensors, to recognize dangerous situations and to counteract either actively, e.g. by warning or emergency brake assist or to warn the driver specifically. Furthermore, it is known to present the driver through the use of cameras mounted on the car other perspectives than that which the driver has in the driver's seat. For example, many motor vehicles are equipped with reversing cameras, which in some countries are now legally required. If the driver engages a reverse gear, a camera image of the reversing camera is automatically switched to a display device in the cockpit.

Furthermore, it is known to synthesize a view from images of several cameras, for example a bird's eye view, which shows the motor vehicle and its surroundings from above.

• - Anzeigen von ausschließlich der Umgebung des Fahrzeugs in der synthetisierten Vogelperspektive auf der Anzeigeeinrichtung;
• - Erkennen, ob eine aktuelle Fahraufgabe gegeben ist, dem die Anzeige einer vor, neben oder hinter dem Fahrzeug liegenden Umgebung auf der Anzeigeeinrichtung zugeordnet ist, und
• - sofern eine solche Fahraufgabe erkannt wird und solange sie gegeben ist, automatisches und ausschließliches Anzeigen der der Fahraufgabe zugeordneten vor, neben oder hinter dem Fahrzeug liegenden Umgebung auf der Anzeigeeinrichtung.

From the DE 10 2015 000 794 A1 is a method for displaying an environment of a vehicle, in particular a motor vehicle, on a display device using an all-round display device having a plurality of camera devices arranged at different positions on the vehicle and a display device, and wherein the all-round display device is adapted to View the surroundings of the vehicle in a synthesized bird's eye view and in representations of the detected by the camera devices surrounding areas of the vehicle on the display device, the method comprising the following steps in the order given:

• Displaying exclusively the surroundings of the vehicle in the synthesized bird's-eye view on the display device;
• Detecting whether there is a current driving task to which the display of an environment lying in front of, beside or behind the vehicle is assigned on the display device, and
• - If such a driving task is detected and as long as it is given, automatic and exclusive display of the driving task associated before, next to or behind the vehicle environment on the display device.

Some dangers can not be adequately addressed by the prescribed systems. For the driver due to its usually relatively centrally located in the motor vehicle position difficult to see places can represent accident risks. Dropping out of a driveway, for example, poses a potential danger to both the driver of the motoring vehicle as well as to approaching vehicles, cyclists and pedestrians. Before the driver can recognize the possible danger from his point of view, the front of the motor vehicle has already penetrated far into the danger zone.

Thus, the task of developing a method for displaying an environment of a motor vehicle, computer program products and motor vehicles of the type mentioned in such a way that the driver receives better insight into hard to see areas and can react earlier.

The object is achieved by a method for displaying an environment of a motor vehicle according to claim 1, a computer program product according to the independent claim 6, a motor vehicle according to the independent claim 8 and a motor vehicle according to the independent claim 9. Further developments and further developments are the subject of the dependent claims , A method is disclosed for displaying an environment of a motor vehicle on a display device using a panoramic display device having a plurality of camera devices disposed on the motor vehicle at different positions, the all-round display device being configured to view the surroundings of the motor vehicle in a synthesized bird's-eye view in a first step by environmental sensors at least one object is detected in at least one surrounding area, wherein in a subsequent step, the display device from a bird's-eye view of a representation of the at least one Surrounding area is switched, in which the at least one object was detected.

The environmental sensors may be, for example, cameras, ultrasound, radar and / or lidar sensors.

For example, if the driver of the motor vehicle drives out of a driveway and cross traffic is detected by the method, a bird's-eye view of a camera can be switched to a view showing the cross traffic. This can be done, for example, by cameras in the front of the motor vehicle, which detect areas to the left and right of the motor vehicle. This gives the driver a much earlier insight and can respond to risky situations, in particular collision, in time and, for example, stop the vehicle before an actual collision hazard occurs.

In a first further embodiment, it may be provided that a collision check is performed between the at least one object and the motor vehicle on the basis of the respective trajectories of the object and of the motor vehicle.

The trajectories can be calculated based on the absolute changes in the positions of the object and the motor vehicle or the relative position of the object and the motor vehicle relative to each other.

In this case, a warning to the driver can be generated early. This embodiment also works when the object is immovable. In this case, the trajectory of the object consists of a single point, and in relative terms the motor vehicle and object may be on a collision course.

In another further embodiment, it can be provided that a changeover to the representation of the at least one surrounding area only takes place if a risk of collision exists. This allows the driver to be aware of risks.

In another further embodiment, it can be provided that the detection of the at least one object and the switching of the display device are carried out on the basis of a self-learning algorithm.

In this way, the algorithm can continue to improve over time and also adjust to the individual driving style of the respective driver of the motor vehicle.

A first independent subject matter relates to a computer program product having a computer readable storage medium embedded with instructions that, when executed by a computing unit, cause the computing unit to be configured to perform the method of the type described above.

A first further embodiment may provide that the computer program product includes a self-learning algorithm.

Another independent subject relates to a motor vehicle having a computer unit with a computer-readable storage medium, wherein a computer program product of the aforementioned type is stored on the storage medium.

Another independent object relates to a motor vehicle with a panoramic display device having a plurality of camera devices arranged on the motor vehicle at different positions, the panoramic view display device having a computing unit that is adapted to the environment of the motor vehicle in a synthesized bird's eye view and in representations be displayed on a display device detected by the camera devices surrounding areas of the motor vehicle, wherein the arithmetic unit is adapted to detect from signals of the environmental sensors at least one object in at least one surrounding area, wherein the arithmetic unit is adapted to the display device from a bird's eye view of a representation of the at least one surrounding area in which the at least one object has been detected.

In a first further embodiment, it may be provided that the arithmetic unit is connected to a direction indicator, wherein the arithmetic unit is adapted to switch the display to a surrounding area in the direction of the indicated direction of travel.

In this way, the planned direction of travel can be specifically incorporated into the control of the display device.
