Description

[0001] The invention relates to a method for displaying trip-related and / or vehicle-specific data displayed on a display surface of a portable electronic device. The data is provided by a motor vehicle.

[0002] A display device for presenting vehicle and / or driving information can use portable electronic devices. Such a device with a display surface could be, for example, data glasses.

[0003] Display devices for presenting vehicle and / or driving information using data glasses are known from various publications. US 2006 / 0 012 884 A1 describes a portable diagnostic device with an HMD (Head Mounted Display) that displays vehicle-related data. EP 1 990 674 A1 and DE 100 13 478 A1 also describe data glasses that can display vehicle-related or driving-specific data. Data glasses are not only used to display vehicle-related data but are also used for driver training, for example, by displaying virtual driving scenarios via the data glasses, as described in DE 102 56 612 B3. Another possible application of data glasses, for example, arises from the document US 2012 / 0 078 686 A1, in which a status display (parking status system) for a vehicle in a parking lot is described.

[0004] US 2010 / 0 057 308 A1 describes an instruction system for a vehicle. The system includes a condition sensor configured to detect at least one vehicle condition, a portable user interface device, and a position detection system configured to detect a user's position relative to a vehicle component. Each instruction is associated with a vehicle condition and the user's position relative to the vehicle component. A controller of the instruction system is configured to select one of the plurality of instructions based on the vehicle condition and the user's position and provide it to the user via the user interface device.

[0005] The invention is based on the object of displaying a certain amount of trip-related and / or vehicle-specific data to a user on a display surface of a portable electronic device at a certain suitable time.

[0006] The problem is solved by the subject matter of the independent claims. Advantageous developments of the invention result from the features of the dependent claims.

[0007] The method according to the invention serves to display trip-related and / or vehicle-specific data. This data is provided by a motor vehicle and displayed to a driver on a display surface of a portable electronic device during and / or after exiting the motor vehicle. The display surface is controlled by a control device depending on a detection signal from a detection device, which detects the behavior of a motor vehicle user when the motor vehicle is parked and signals this via the detection signal. In other words, information, i.e. trip-related and / or vehicle-specific data, can be displayed on a portable electronic device with a display surface, e.g., data glasses, when exiting a motor vehicle, so that the driver does not have to remain in the motor vehicle to read and / or record the data, but can set off immediately.

[0008] For example, vehicle-specific data may represent a remaining range or a predicted time to charge a battery or a battery level, or general information relating to the motor vehicle. Trip-related data, on the other hand, may include information on a route or a trip time or a mileage or a location of the motor vehicle, or general information relating, for example, to the last trip, particularly independent of a specific trip, with the motor vehicle. This offers the advantage that trip and vehicle information can be provided to the user via a portable electronic device with a display interface.

[0009] The portable electronic device with a display can display trip-related and / or vehicle-specific data. For example, the portable electronic device with the display interface can be a pair of data glasses, a smartphone, or a tablet PC.

[0010] The invention provides that the display surface of the portable electronic device is controlled by a control device in dependence on a detection signal of a detection device which signals a behavior of a vehicle user.

[0011] According to the invention, data is displayed upon request from the device. If, for example, the control device detects behavior on the part of a motor vehicle user, such as fixating their gaze on the motor vehicle and / or motor vehicle-specific components, information can only be displayed to the user upon request from the device and with confirmation from the user. Confirmation can be provided in the form of a predetermined body movement, such as "nod" or a predetermined touch option, such as tapping the display surface of the portable electronic device. This has the advantage that the user can decide for themselves whether they would like to receive information on the fill level or range when looking at their fuel cap, for example, without data automatically appearing on the display surface of the device as a result of fixating their gaze.The provision of component-related data triggered by approaching vehicle-specific components can be realized, for example, using the function library for augmented reality representations from the company Metaio.

[0012] The behavior could, for example, be gaze fixation. A user can, for example, fixate their gaze on the fuel cap of their vehicle. This gaze fixation can, for example, display the fuel level. This has the advantage that the user is informed about all components of their vehicle through gaze fixation. If the user looks at objects that have no connection to their own vehicle, or at other unfamiliar vehicles in the immediate vicinity, no related data will be displayed to the user. Gaze fixation can, for example, be detected by vehicle gaze detection for vigilance monitoring. Gaze fixation can be carried out using data glasses, as is known, for example, from gaze-controlled menu navigation for such data glasses.

[0013] Another behavior can be approaching the motor vehicle and / or motor vehicle-specific components. For example, if the motor vehicle user approaches the trunk of their motor vehicle to load a piece of luggage, the user can be shown in advance by approaching the trunk how much storage space is still available in the trunk or how heavy the additional piece of luggage can be so that the motor vehicle is not overloaded, for example. If a motor vehicle user returns to their motor vehicle after parking their motor vehicle in a location they know, they can be shown vehicle-specific information that is important for their onward journey, such as the remaining range on their fuel tank. This has the advantage that a motor vehicle user does not have to remain in the vehicle to receive journey-related and / or vehicle-specific data.Proximity detection can be implemented, for example, using ultrasonic sensors, such as those used in alarm systems.

[0014] Another possible behavior can include exiting and / or leaving the vehicle. As soon as the vehicle user has parked their vehicle (i.e., with the ignition switched off), and exits and / or exits their vehicle, current trip-related and / or vehicle-specific data can be displayed. For example, if a vehicle user parks their vehicle in an unfamiliar location, their current location can be displayed. Exit detection can be implemented, for example, using cameras or seat occupancy detection.

[0015] A further embodiment of the invention provides for the data to be displayed on a display surface of a portable electronic device only after confirmation by a predetermined body movement or by a predetermined touch option on the display device. A body movement here is to be understood as, for example, a nod or a rotation of the user's head in a certain direction or a shaking of the head. Touch options can be considered to be, for example, tapping the display surface or pressing a button on the device. If, for example, the control device detects behavior of a motor vehicle user, such as gaze fixation, information can be displayed to the user only upon request from the device and / or further options for obtaining information can appear on the display device.If a motor vehicle user looks at the fuel cap of their vehicle, for example, the device can prompt them and / or simultaneously display options. The user can then decide, for example, whether they would like to receive information about the fill level in their tank. Further options can also be offered, whereby they can, for example, "answer" the question "yes" (option 1), "neg" (option 2) or receive "other information about the tank" (option 3). The user can "answer" the question "yes" by moving their head "up and down" (nodding) or "neg" the question by moving their head from "left to right". "Other information about the tank" can be displayed, for example, by tapping the display surface. This has the advantage that the motor vehicle user is not overloaded with data and can determine the amount of data that should be available to them.

[0016] The invention also includes a device for displaying trip-related and / or vehicle-specific data of a motor vehicle, which is designed to carry out an embodiment of the method according to the invention. The device comprises a portable electronic device and a control device, wherein the control device is designed to display the data using the electronic device depending on a detection signal from a detection device that signals a vehicle user's behavior when the motor vehicle is parked. Furthermore, the control device is configured to display the data upon request from the device.

[0017] An exemplary embodiment of the invention is described below. The single figure shows an embodiment of the method according to the invention.

[0018] The exemplary embodiment explained below is a preferred embodiment of the invention. However, in the exemplary embodiment, the described components of the embodiment each represent individual, independently considered features of the invention, which also further develop the invention independently of one another and are thus to be considered a component of the invention, either individually or in a combination other than the one shown. Furthermore, the described embodiment can also be supplemented by further features of the invention already described.

[0019] The figure shows a motor vehicle 1 and a user 2 of the motor vehicle 1. The motor vehicle 1 can be, for example, a motor vehicle, in particular a passenger car. The user 2 wears an electronic device 3. The electronic device 3 can be, for example, data glasses or augmented reality glasses or another of the aforementioned portable electronic devices. By means of the electronic device 3, trip-related and / or vehicle-specific data D1, D2, D3 can be displayed on a display surface 4 of the portable electronic device 3.

[0020] A recognition device 5, which can also be provided in device 3, can recognize a behavior 6 of the user 2 and signal it with a recognition signal. Behavior 6 can include getting out of the motor vehicle 1 and / or leaving the motor vehicle 1. As soon as the user 2 has parked their motor vehicle 1 and leaves it and / or gets out of it, trip-related and / or vehicle-specific data D1, D2, D3 can be displayed on the display surface 4. If a user 2 parks their motor vehicle 1 in an unfamiliar location, for example, their current location can be displayed on the display surface 4. Exit detection can be implemented, for example, using a camera or seat occupancy detection.

[0021] A further behavior 6 can be signaled by approaching the motor vehicle 1 and / or vehicle-specific components. If, for example, a user 2 returns to his motor vehicle 1 after parking his motor vehicle 1 in a location known to him, vehicle-specific and / or trip-related data D1, D2, D3, for example, important information for his onward journey, such as the remaining range of his fuel tank, can be displayed on the display surface 4. Proximity detection can be implemented, for example, by ultrasonic sensors, such as those used in alarm systems.

[0022] To ensure that not all journey-related and / or vehicle-specific data are displayed to the user 2 upon approaching the motor vehicle 1 and / or motor vehicle-specific components on the display surface 4, information can only be displayed to the user 2 upon request from the device 3 and with confirmation from the user 2. Confirmation by the user 2 can occur, for example, through a predetermined body movement or through a predetermined touch option on the display surface 4. A body movement here is to be understood as, for example, a nod of the head or a turning movement of the head in a certain direction or a shaking of the head. Touch options can be considered, for example, tapping the display surface or pressing a button on the device 3. If a user 2 approaches the fuel cap of his motor vehicle 1, for example, the device 3 can prompt and / or simultaneously display options.Accordingly, user 2 can now decide, for example, whether they would like to receive information about the fill level of their tank. They can also be offered further options, for example, by "yes" (option 1) or "neg" (option 2) to the query, or by receiving "other information about the tank" (option 3). The user can "yes" to the query by moving their head "up and down" (nodding) or "neg" the query by moving their head from "left to right." "Other information about the tank" is obtained, for example, by tapping the display surface 4.

[0023] Then the data D1, D2, D3 can be transmitted from the motor vehicle to the device 3, e.g. via a radio connection or e.g. via a Bluetooth connection, and displayed on the display of the device.

[0024] Overall, this results in a method in which a driver, upon exiting a motor vehicle, can have information—i.e., journey-related and / or vehicle-specific data—displayed on a portable electronic device with a display interface, e.g., data glasses. This means that the driver does not have to remain in the vehicle to read and / or record the information, but can set off immediately. To avoid overloading the driver with information, the data can also be provided via the glasses, e.g., upon request from the device. Information can then be displayed by the driver nodding or tapping the data glasses (device).
