Description

The invention relates to a human-machine interface for a motor vehicle and a system for controlling electrical consumers in a motor vehicle, which are designed such that the functions of selected electrical consumers of the motor vehicle are also available after switching off the motor vehicle.

For ordinary motor vehicles man-machine interfaces are known, which allow a configuration that should meet the personal preferences of a user of the motor vehicle.

Also, with the increasing integration of software systems in automobiles, ordinary automobiles are increasingly equipped with a variety of electronic components and functions. The components mentioned in a motor vehicle include, for example, a navigation system, a telephone system or an Internet communication system. The functions mentioned include, for example, an air conditioning of the motor vehicle, a log book, that is a vehicle operating instructions in electronic form, and a seat adjustment. In addition to these components and functions, ordinary motor vehicles increasingly also have a large number of other electrical consumers, which are available in the majority for functions which serve solely comfort.

From the publication DE 10 2011 106 357 A1 A system for operating and remotely configuring a motor vehicle using a personal calendar is known. In this case, the motor vehicle can be configured such that vehicle data depend on calendar data of a personal calendar of a user of the motor vehicle.

Object of an embodiment of the invention is to provide a man-machine interface for a motor vehicle and a system for controlling electrical consumers of a motor vehicle, which are simple in design and with which the comfort for a user can be further increased.

According to one embodiment, this object is achieved by a man-machine interface for a motor vehicle. The human-machine interface in this case has a means for displaying electrical consumers of the motor vehicle, which are active on. Furthermore, the man-machine interface has a means for selecting the active consumers to be deactivated in the event that the motor vehicle has been parked on.

The basic idea is thus to set up a user interface via which a user of the motor vehicle can control electrical consumers of the motor vehicle in such a way that the functions of the electrical consumers are also available after the motor vehicle has been switched off.

Such a man-machine interface has the advantage that it is simply designed and with this the comfort for a user can be further increased. Thus, man-machine interfaces for ordinary motor vehicles are known, which have means for displaying active consumers and means for configuring the motor vehicle. Such a human-machine interface can thus be realized easily and without great effort by known and common components of ordinary man-machine interfaces for motor vehicles or be implemented in these, without costly and costly conversions and software changes would be needed. Furthermore, situations are possible in which a user of the motor vehicle also wants, after the motor vehicle has been switched off, to resort to functions of electrical consumers of the motor vehicle, for example to a device of an infotainment system of the motor vehicle or to charge a mobile telephone. In this case, the human-machine interface is designed to automatically indicate to a user of the motor vehicle, in the event that the motor vehicle has been parked, which electrical consumers of the motor vehicle are active. Further, the user of the motor vehicle can easily and intuitively select those electrical consumers whose function is to be available even after the motor vehicle has been switched off, that is, which are not to be deactivated directly with the motor vehicle, so that the comfort for the user of the motor vehicle can be significantly increased here.

In one embodiment, the means for displaying may be a touch screen.

Further, the means for selecting may be a touch-sensitive surface of the touchscreen.

A touch screen is a display that detects and responds to a touch in a display area, causing direct interaction with the display without keyboards, mouse devices or touch pads. By means of such a touch screen, therefore, the handwriting, that is the touch of a user, can be recognized and converted into commands. Also, the touch-sensitive surface for text recognition or movement of a pointer on the Screen, that is the touch screen, serve. Furthermore, such touchscreens are known in an ordinary motor vehicle, for example, as a display device for an infotainment system of a motor vehicle, so that this can be realized here simply and without much effort.

According to one embodiment, the means for selecting is designed such that all active electrical consumers of the motor vehicle are deactivated together.

Also, the means for selecting can be designed such that the active electrical consumers of the motor vehicle are each deactivated separately.

Furthermore, the means for selecting can also be designed in such a way that the active electrical consumers of the motor vehicle are deactivated in groups, wherein at least one electrical consumer is assigned to each group.

The means for selecting can thus be designed such that a user of the motor vehicle can individually select all the electrical consumers of the motor vehicle which are to remain active even after the motor vehicle has been turned off, but this is also given the option of individual groups of electrical consumers and all To be able to select consumers together if the user of the motor vehicle wants to access the functions of these electrical consumers even after the motor vehicle has been switched off. The classification of electrical consumers of the motor vehicle in groups can be done, for example, based on the functions of the electrical consumers or their arrangement within the motor vehicle. The man-machine interface is thus designed such that a user, if he wants to access after switching off the motor vehicle on functions of several electrical consumers of the motor vehicle, not each of these electrical loads must individually select, whereby the comfort of the user can be further increased ,

Also, the man-machine interface may further include a second means for selecting a time period for which the active electrical loads not to be deactivated remain active. In this way it can be ensured that the electrical consumers, which a user of the motor vehicle would like to access even after the motor vehicle has been switched off, only remain activated as long as the user wants to access the functions of these electrical consumers, so that an unnecessary power consumption by the still activated electrical consumers can be prevented.

According to one embodiment, the second means for selecting is designed such that the period for each active electrical load can be selected separately. This has the advantage that a user of the motor vehicle can adjust the period for which the functions of individual electrical consumers of the motor vehicle can still be used after the motor vehicle has been parked, according to his habits, that is, on the one hand to continue to use the functions and on the other hand one to prevent unnecessary power consumption. As a result, the comfort for a user can be further increased.

Furthermore, the second means for selecting can also be designed such as to select the period of time which corresponds to the longest period requested by one of the active electrical consumers. This proves to be advantageous, in particular, if the electrical consumers, whose functions are to be accessed even after the motor vehicle has been switched off, are selected in groups, for example, according to their functions. This ensures that all still active electrical consumers remain active until a user has completed all desired operations or would like to access any of the electrical consumers more and the electrical consumers are not previously disabled, resulting in a further increased comfort for the user ,

Furthermore, the selection of the period for which the active electrical consumers, which are not to be deactivated, remain active can also be controlled by the electrical consumers themselves. This can be done for example by determining the still active use of an electrical load, in particular by determining the resulting increased or varying power consumption compared to the quiescent current, or via wireless communication between the still active electrical load and the vehicle itself, based on a demand message. This may be the case, for example, when a connected electrical consumer still has to stop or activate a function, for example, data synchronization, maintenance of a state of charge of an electrical consumer or any preparations prior to departure such as air conditioning of the motor vehicle.

Also, the means for displaying may be configured to issue an indication if an electrical load of the motor vehicle has been deactivated. The means for displaying can thus be designed to issue an optical indication, if an electrical consumer of the motor vehicle has been deactivated, for example, because this was not selected via the means for selecting or the period for which the corresponding electrical consumer should remain active, has expired, so that a user can be additionally signaled that the corresponding functions of the electrical load not More available and can be used, so that the comfort can be further increased.

A further embodiment of the invention also provides a system for controlling electrical consumers of a motor vehicle, which has a human-machine interface described above and a third means for detecting whether the motor vehicle is parked.

Such a system has the advantage that this is simple and with this the comfort for a user can be further increased. Thus, both man-machine interfaces and means for detecting whether a motor vehicle is parked are known for ordinary motor vehicles. Such a system can thus be realized easily or without great effort by known and common components and functions of ordinary motor vehicles or implemented in these, without costly and costly modifications and software changes would be needed. Furthermore, situations are possible in which a user of the motor vehicle also wants to access functions of electrical consumers of the motor vehicle after the motor vehicle has been shut down, for example, to a device of the infotainment system of the motor vehicle or to charge a mobile telephone. In this case, the system is designed to automatically indicate to a user, in the event that the motor vehicle has been parked, which electrical consumers of the motor vehicle are active. Furthermore, the user of the motor vehicle can simply and intuitively select those electrical consumers via the man-machine interface whose function should also be available after switching off the motor vehicle, that is to say which are not to be deactivated directly with the motor vehicle, so that the comfort for the user of the motor vehicle can be significantly increased here.

The third means may be an engine control of an engine of the motor vehicle. Since data from an engine control vehicle speed can be obtained and thus can be derived whether the motor vehicle is ever moved, can be determined based on this component easily and without much effort, whether the motor vehicle actually parked, that is parked. Since engine controls are still part of ordinary motor vehicles, the third means is designed to realize this easily and without great effort by components and functions of a common motor vehicle without additional components or complex and costly modifications would be needed. Furthermore, however, the third means can also be configured to evaluate the data of further sensors present in a standard motor vehicle and thereby to detect whether the motor vehicle is parked, for example by means of data from a handbrake sensor. Thus, hand brakes, which are also referred to as parking brakes, usually operated only for detecting a parked vehicle.

According to one embodiment, the system can further store an electrical energy store which stores electrical energy for operating the electrical consumers, an evaluation unit for detecting a state of charge of the electrical energy store, a comparator for comparing the state of charge with a desired value and a fourth means for deactivating the still active electrical Consumers, if the state of charge is less than the setpoint, have. So it can be further ensured that it does not come to an excessive emptying of the energy storage, which is, for example, a vehicle battery by using the electrical load of the motor vehicle even after stopping the vehicle, so that in the case of a restart of the motor vehicle yet enough energy for the operation of the electrical load of the motor vehicle, that is the associated components and functions, is present in the energy storage. Thus, the operation of the still active electrical loads can be adjusted in time if the state of charge of the energy storage has dropped below a critical state of charge and this should soon be recharged before temporarily or temporarily inoperative on the functions and / or components of the electrical consumers which could lead to a noticeable loss of comfort. In this case, it is also possible to signal this to the user, in particular in the form of a warning signal, whereby the comfort can be further increased.

With a further embodiment of the invention, also a motor vehicle is specified, which comprises a system described above. Such a motor vehicle has the advantage that this is simple and with this the comfort for a user can be further increased. Thus, such systems can be implemented easily or without great effort by known and common components and functions of ordinary motor vehicles or implemented in these, without consuming and costly conversions and software Changes would be needed. Further, situations are possible in which a user of the motor vehicle also wants to use functions of electrical consumers of the motor vehicle after the motor vehicle has been switched off, for example to a device of an infotainment system of the motor vehicle or to charge a mobile telephone. Such a motor vehicle further has the advantage that a user of the motor vehicle in the case that the motor vehicle is parked, that is parked, can be automatically displayed, which electrical consumers of the motor vehicle are active. Further, the user of the motor vehicle can easily and intuitively select those electrical consumers whose function should also be available after switching off the motor vehicle, that is, which should not be deactivated directly with the motor vehicle, so that the comfort for the user of the motor vehicle significantly increases here can be.

The electrical consumers may be a mobile telephone and / or a device of an infotainment system and / or a vehicle function and / or an additional device. Thus, the increasing demand for additional devices, which can be integrated in particular with the wireless communication in the motor vehicle and provide a user of the motor vehicle higher comfort, such as refrigerators or wireless navigation devices, bill. Also, motor vehicles are more and more equipped with infotainment systems, which include a variety of wireless devices and serve to provide infotainment programs and / or information programs for the users of the motor vehicle. For example, information programs can be provided which support a driver of the motor vehicle in a variety of driving situations by retrievable information or automatically outputable instructions and / or automatically perform the driving behavior of the motor vehicle related actions, whereby the ride comfort can be increased while reducing the risk of accidents. The vehicle functions can also be, for example, vehicle air conditioning or control of the lighting systems of the motor vehicle. Thus, it can be ensured, for example, that even after the motor vehicle has been switched off, it can be heated to a specific temperature.

In summary, it should be noted that the present invention, a man-machine interface of a motor vehicle and a system for controlling electrical consumers of a motor vehicle are given, which are simple in design and with which the comfort for a user can be significantly increased.

Thus, such a man-machine interface or such a system can be realized simply and inexpensively by extending existing vehicle systems. Also, a user of the motor vehicle is given the opportunity to easily and intuitively select those electrical consumers whose functions are to be available even after parking the motor vehicle.

Since a period of time for which the electrical loads should remain activated after the motor vehicle has been switched off can be defined, further unnecessary power consumption can be prevented.

In addition, the power consumption of the electrical consumers can be further regulated such that, if the state of charge of an energy storage, which stores energy for operating the electrical consumers, has fallen below a critical state of charge, the still active electrical consumers are disabled, especially before a restart of the Motor vehicle temporarily on the functions and / or components of the electrical load completely or partially inaccessible, which would result in a large loss of comfort.

The invention will now be explained in more detail with reference to the accompanying figures.
