Abstract

Motor vehicle comprising at least one seat (2) with a headrest (3), wherein in the headrest (3) at least one charging element (6) for inductively charging an electronic device (13) is integrated.

Description

  • The invention relates to a motor vehicle comprising at least one seat with a headrest.
  • Increasingly, people in a motor vehicle are carrying electronic portable devices that have an integrated battery that is to be charged from time to time. An example of such a mobile device is a mobile phone or smartphone or a tablet, another example is so-called smart glasses, into which information can be read that the wearer can read. In most cases, the charging of the accumulator takes place externally of the vehicle, that is to say at a charging station located at home, since usually no charging connections are present in the vehicle, in particular since the different types of devices generally also have different connection configurations.
  • The invention is therefore based on the problem to provide a motor vehicle, which is improved compared to the.
  • To solve this problem is provided according to the invention in a motor vehicle of the type mentioned that at least one charging element for inductive charging of an electronic device is integrated in the headrest.
  • The invention is based on the consideration that an in-vehicle person usually carries the electronic mobile device with him, so carries for example in the jacket or shirt pocket with him, or wears the same in the case of data goggles on the head. For persons sitting in the car seat, this applies in a similar way, that is to say that their electronic devices are also located near the headrest of the front seat behind which they are seated. Often, for example, in the case of tablets, these for viewing a film or the like also headrest side attached via corresponding holder so that they are also located near the headrest. According to the invention, a charging element for inductive charging of an electronic device is now integrated in such a headrest. This charging element, ie a primary coil, is traversed by a charging current. If the electronic device has a corresponding charging interface with a corresponding secondary coil, then a current is induced in the device-side secondary coil via the magnetic field generated by the current-carrying primary coil, which is used to charge the accumulator of the electronic device.
  • This means that in the motor vehicle according to the invention, each electronic device with a corresponding inductive charging device is automatically charged as soon as it is in the sphere of action of the inductive charging device of the headrest.
  • According to an expedient development of the invention, it can be provided that at least one unidirectional communication takes place via the charging element between a control device provided on the vehicle side and the connected device, so that the operation of the connected device can be controlled via the control device. According to this embodiment of the invention, it is not only possible via the inductive charging interface to carry out the accumulator charge, but also to transmit control data, at least in unidirectional direction, from a vehicle-side control device to the device coupled via the inductive charging device. The vehicle-mounted control unit, which is connected via an interface with the on-board electronics, in this way, the operation of the device at least rudimentary control. This control can in particular be of the form that the ongoing operation of the device is temporarily or completely interruptible as a function of at least one operating parameter of the motor vehicle. This means that the device can be switched off temporarily or permanently if necessary, depending on the given operating or driving situation. This makes it possible not only to load an operating device in operation, but also to turn off the device, for example, if this is required for safety-related aspects. Particularly noteworthy here is the operation of data glasses, which must not be operated while driving. The possibility of automatically interrupting the operation of the data glasses, ie the reflection of information, by the motor vehicle when one or more specific boundary conditions are met, is thus of particular advantage from a safety point of view.
  • Such an operating parameter may be the driving speed, the operation being interruptible when the driving speed is equal to or below a limit speed. This limit speed may for example be 3 km / h, preferably it is set at 0 km / h, that is to say that the device, in particular the data glasses, can only be operated when the vehicle is actually stationary.
  • Alternatively, the operating parameter may also be the engine operating condition, with the operation of the apparatus being interruptible when the engine is stopped. This is the case, for example, when the vehicle is at a traffic light and, for example, the engine has been automatically switched off via an automatic start-stop system. In this case, for example, the data glasses would be operable because the engine is off. However, once the engine is restarted, which in the case of automatic start-stop automatically, the operation of the data glasses is interrupted immediately.
  • However, interruption is not only useful in the case of data glasses. Also in the case of a coupled smartphone, this may be appropriate, especially if the paired smartphone is assigned to the driver. For even a smartphone should not be operated while driving, especially if no speakerphone is installed in the vehicle. If, of course, a speakerphone is installed and the driver is talking on the phone, interruption is of course excluded.
  • The interruption operation can take place automatically if a corresponding boundary condition is met. This means that the system is activated almost immediately when the ignition is switched on. Actuation of a corresponding system activating switch or the like is not required. Alternatively, the system can be activated only upon actuation of an on-vehicle actuator, that is, the interruption of the operation is only switched on when the actuator is operated.
  • According to an expedient development of the invention it can be provided that the type or the type of the connected device and / or the relative position of the connected device for headrest can be determined via the control unit. About the type or generic recognition can be detected, for example, whether it is the paired device is a data glasses or a mobile phone or the like. In this case, a quasi-bidirectional communication would be expedient, since the control unit must query corresponding identification data from the coupled electronic device. If, for example, data goggles are detected, the automatic switch-off mode can be activated. If, on the other hand, a mobile phone is detected, it can be omitted, only inductive charging takes place.
  • Alternatively or expediently, the control unit can also determine the relative position of the connected device for the headrest. This can be used to determine whether the coupled electronic device is assigned to the driver or a person sitting in the rear. If it is a device associated with a person sitting in the rear seat, the automatic shut-off mode, for example, can be suppressed from the inside, and only charging is required. Because it does not pose a security risk if a person sitting in the rear, for example, has a data glasses and uses them, or operated a smartphone or the like. If, however, it is determined that the coupled electronic device is to be assigned to the driver, the automatic switch-off mode can also be activated, for example, depending on a type identification, so that not only charging but, if required, also terminating the operation.
  • The detection of the relative position can take place via a corresponding antenna module, via which the electronic device is detected, which also has, for example, a corresponding antenna or a transponder or the like.
  • Finally, it is expedient if at least one fastening element and / or at least one compartment for receiving the unused device is provided on the headrest. In some countries, for example, the use of data glasses is inherently inadmissible, which means that the driver is not allowed to wear them at all. In this case, it is expedient to attach these data glasses to a suitable fastener on the headrest or place it in a corresponding receptacle there, so that their battery is charged inevitably.
  • Further advantages and details of the invention will become apparent from the embodiment described below and from the drawing.
  • This shows as a partial section of a motor vehicle according to the invention 1 a seat shown here with dashed lines 2 with a headrest arranged thereon 3 and a person sitting on the seat 4 , of which in the schematic diagram only the indicated head 5 is shown.
  • The headrest 3 is with an inductive charging element 6 provided, that is, a primary coil, via a connecting line 7 with the on-board electronics 8th , which is also shown here only in principle, is connected. The on-board electronics 8th includes a controller 9 that is on a communication bus 10 accesses, via the control unit 8th to a power supply of the inductive charging element 6 is controlled. On the other hand, this can also be a control command to the inductive charging element 6 to be given, via the charging element 6 can be given to an inductively coupled with him electronic device. This can be transmitted as a corresponding higher-frequency modulated signal, so that a control of the electronic device, which will be discussed below, is possible. The device is able to capture and evaluate this control command.
  • The inductive charging element 6 is used for inductive charging of an accumulator or energy storage of an associated electronic device. Alternatively, here is the possibility of a headrest side integrated Charging port facility 11 shown, for example, a USB port or the like, of course, several such, possibly different charging terminal devices may be provided. To this charging terminal device, an electronic device can be connected by means of a cable.
  • Finally, at the headrest 3 another storage device 12 , For example, provided a hook or a receptacle on which, respectively, in which an electronic device that is not needed, can be stored.
  • The figure shows an example of an electronic device 13 in the form of data glasses 14 that is here from the person 4 will be carried. The data glasses 14 makes it possible to reflect on the glasses corresponding information that can be viewed by the wearer. It has an accumulator 15 to which an inductive charging device 16 , So a secondary coil is assigned. This works with the inductive charging element 6 the headrest 3 together. A charging current can be induced when the charging device 16 in the area of action of the current-carrying charging element 6 is, so the person 4 on the seat 2 Has taken his place and his head 5 near the headrest 3 located.
  • This inductive charging operation can automatically take place whenever the person 4 on the seat 2 Takes place, which can be done for example by detecting a seat occupancy sensor. The control unit 9 then automatically switches the charging element 6 to. The operation can also be of the kind that, after one is not sure that the person 4 always such an electronic device 13 with you, the person 4 first an actuator 17 For example, to actuate a key or the like, via the control unit 9 to select the inductive charging mode. Finally, it is conceivable that initially via the control unit 9 initiated detection of the type or genus of any in the sphere of action of the charging element 6 located electronic device 13 takes place, for example by a kind of communication link between the charging element 6 and the charging device 16 is built, or a kind of transponder interrogation of a not shown in detail, on the data glasses 14 existing transponder or the like. The control device 9 can recognize this by what type or type of electronic device 13 it is, and whether it needs a charge or not. Only when it is a device that is even able to be inductively charged, then can the charging element 6 be switched on.
  • At the electronic device 13 , here the data glasses 14 , is further a controller 18 provided the operation of the data glasses 14 controls. This control device 18 can now via the control unit 9 be controlled by a control command to the charging device via the inductive charging element 16 is transferred, wherein the control device 18 is able to capture and process a corresponding control command. This makes it possible via the control device 9 for example, the basic operation of the data glasses 14 switch on or off. This can take place as a function of one or more operating parameters of the motor vehicle, for example as a function of the actual speed with which the vehicle is moving. The operation of such data glasses 14 may be omitted, for example, when the vehicle is moving. Is over the data bus 10 on the part of the control device 9 detects a speed greater than a limit speed, for example, 0 km / h or 2 km / h, it is via the control unit 9 and the charging element 6 a control command to the charging device 16 and thus to the control device 18 the data glasses 14 given that their operation is to end immediately. During the vehicle movement so can the data glasses 14 not used. Only when the vehicle is stationary, can via the control device 9 a new command on the inductive coupling to the controller 18 be given that the data glasses 14 can be operated again. As an alternative to the actual speed, the operating parameters may depend on the operation of the data glasses 14 be switched on or off, for example, be the engine operating state. Only when the engine is stopped can the data glasses 14 operated, the engine is running, so it is off. This condition can also be over the data bus 10 from the controller 9 detected and the inductive connection according to a control command to the controller 18 be communicated.
  • Furthermore, there is the possibility of the relative position of the electronic device 13 relative to the headrest 3 capture. This too can be done via the charging element 6 respectively. For example, is located on the electronic device 13 a kind of transponder whose relative position to the charging element 6 can be detected by this. It is detected here that the electronic device 13 for example, back to the headrest 3 located, so can the controller 9 (possibly in conjunction with the knowledge that the device type is a data goggles) recognize that in this case a power on or off is not required, since a person sitting in the vehicle fund course the data glasses 14 can also use while driving, the same applies to another electronic device. Thus, there is a relative position detection, wherein, depending on the detected relative position of the operation of the electronic device 13 from the controller 9 can be controlled.
  • That means ultimately that between the loading element 6 and the electronic device 13 respectively whose electronic components an at least unidirectional, upon detection of device type or relative position and a bi-directional communication connection wireless nature is established. In the simplest case, only the charging operation can take place via this wireless connection via the inductive coupling; in a further expansion stage, bidirectional communication can also be used in conjunction with a control of the electronic device 13 via the vehicle-mounted control unit 9 respectively.
  • Exemplary is as another electronic device 13 a mobile phone 22 shown, which is also an inductive charging device 19 in the form of a secondary coil and an associated accumulator 20 having. Is the mobile phone 18 in the sphere of the inductive charging element 6 , so here also the inductive charging operation can take place.
  • The mobile phone 22 also has a control device 21 on. These can equally control commands from the controller 9 of the vehicle via the wireless inductive communication link, in turn, by corresponding higher-frequency modulation. This can also be the mobile phone 22 if necessary in its operation via the control unit 9 to be controlled.
  • Also in the case of the mobile phone 22 It is basically possible to choose the type or genre of this electronic device 13 to recognize, so to grasp that it is a mobile phone. In this case would be on the part of the controller 9 For example, another control mode expire because the operation of the mobile phone 18 It is not necessary to switch off when the vehicle is moving. This especially if the driver is talking on the mobile phone during the vehicle standstill or while driving. Basically, however, there is the possibility, for example, if on the part of the control device 9 it is detected that the driver is the mobile phone 18 if this is running as a smartphone, while driving manually operated. This operating process can be detected, for example, via a camera integrated on the vehicle, corresponding evaluation data are then again on the data bus 10 , Alternatively, this can be done via a communication network of the vehicle, which is a mobile communication of the mobile phone 18 via the vehicle-side antenna allows to be detected.
  • Finally, here also a detection of the relative position of the mobile phone 22 respectively. If it is found that the mobile phone is not in the area in front of the headrest 3 but behind the headrest 3 is, so is an assignment of the mobile phone 22 to on the seat 2 Person not present, so that in principle only one charging operation takes place, but no control intervention, since in this case is not required.
  • Overall, inductive charging offers convenience to the user as they no longer need to remove or plug in the electronic, mobile device to charge it. Rather, there is an automatic inductive charge, possibly after previous actuation of the control element. This means that the device will be charged almost automatically while driving. If control access is possible, the electronic device can also be deactivated as required and, if necessary, reactivated if the boundary conditions so dictate, eg if the use of the electronic device during the journey or in the country in which the vehicle is located is prohibited is.
