Description

  The present invention relates to vehicle navigation technology.

In particular, the invention relates to a navigation system for a complex menu-controlled multifunctional vehicle system, a vehicle having such a navigation system, the use of such a navigation system in a vehicle, a method for assisting a driver of a vehicle , Program elements, and computer-readable media.

  Conventionally, functional components in a vehicle such as an in-vehicle computer, an air conditioner, a radio, and a navigation system are mounted in the vehicle as independent components that can be operated separately. Each independent part has its own operator control panel, which requires the driver to point towards that operator control part or while operating to operate the independent part. Means you need to touch. This often distracts the driver from what is happening in traffic.

  In addition, operator control elements selected for independent components such as call acceptance for mobile phones, volume control, and program selection keys for radio, especially close to the handle or on the handle itself It can be physically placed away from independent parts within reach of the driver. However, this often makes sense only when the vehicle is initially equipped. In addition, the cost is relatively high. In addition, independent components can be combined to form a complex menu controlled multifunction vehicle system. In this case, operator control is concentrated in the operator control interface of the multifunctional vehicle system. By way of example, such a multifunctional system is installed in the area of a conventional radio installation slot and combines the functions of an in-vehicle computer, an air conditioner, a radio, and a navigation instrument. The display of a multifunctional system can be in the form of a sensitive input screen (touch screen display) to allow menu items to be entered by touching the display. Alternatively, the operator control element can be placed directly adjacent to the display.

  The increasing complexity of such a menu-controlled multifunction vehicle system requires the user to go directly towards the operator control interface, thus requiring a direct connection to the operator control purpose, Therefore, there is a risk of distraction from driving.

  Usually, the navigation instrument is the actual navigation (map, map matching, routing, etc.) combined in the instrument, and (for user input etc., the presentation, ie the image for that information, And a man-machine interface (corresponding to audio output).

  It is an object of this invention to provide an improved navigation system that allows safe operation.

  The present invention defines a complex, menu-controlled, multifunction vehicle system, vehicle, use, method, program element, and navigation system for computer-readable media according to the features of the independent claims. Developments of the invention can be found in the dependent claims.

  The described exemplary embodiments relate to means equivalent to navigation systems, vehicles, uses, methods, program elements, and computer readable media.

  In accordance with one exemplary embodiment of the present invention, a navigation system for a complex, menu-controlled, multifunctional vehicle system is described that includes a navigation device, a man-machine interface (MMI, or HMI). And a communication link. The communication link is designed to provide bi-directional communication between the man-machine interface and the navigation device, and the man-machine interface and the navigation device are designed to communicate with each other via the communication link.

  The two units (MMI and navigation device) are housed in separate instruments.

In accordance with a further exemplary embodiment of the present invention, the man-machine interface and the navigation device are designed to be located at separate locations in the vehicle. This segmented design thus allows vehicle navigation and MMI to be developed separately and mounted on the vehicle. In particular, this allows both instruments to fit in different positions in the vehicle.

  As an example, the man-machine interface is installed in the driver's field of view, and the navigation part (navigation device) is installed in the glove box of the vehicle.

  According to a further exemplary embodiment of the invention, the navigation device is designed for mobile communication with a man-machine interface by means of a communication link. Both units can thus be connected by cable or by radio. This connection is used to exchange only the necessary data for each.

  Wireless transmission between the MMI and the navigation device (and vice versa) is performed by, for example, WLAN (eg, 802.11p), Bluetooth, ZigBee, or WiMax.

  In accordance with a further exemplary embodiment of the present invention, the navigation system is designed to send information from the navigation device to the man machine interface for the purpose of evaluating data located within the man machine interface.

  As an example, the MMI has a dedicated computing unit and a dedicated data memory. It is therefore possible for the information to be displayed to be handled in the MMI. For example, the manner in which this information should be handled or displayed can be controlled and inspected by the navigation device.

  According to a further exemplary embodiment of the invention, the navigation device is a module of a driver assistance system. When the following text refers to “navigation device”, this is combined with a simple navigation module (see reference numeral 120 in FIG. 1), or possibly a driver assistance system (see reference numeral 125 in FIG. 1). It is intended to be understood to mean a complex system (see reference numeral 130 in FIG. 1) having both a navigation module and a suitable computing unit and a sensor system.

  In accordance with a further exemplary embodiment of the present invention, the man-machine interface is designed to be partially integrated into the vehicle windshield or in front of the vehicle speedometer. In this case, for example, graphic information is drawn on the windshield. The audible output can be provided by speakers located elsewhere. Control commands are entered by voice control or are located on a central console of the vehicle or using mechanical input devices integrated into mobile devices (PDA, mobile phone, etc.) .

  This allows the driver to record graphical information without being distracted by too much going on and off.

  According to a further exemplary embodiment of the invention, the navigation system further comprises a sensor device for confirming the head position for the driver or occupant with respect to the display device of the man-machine interface.

  According to a further exemplary embodiment of the invention, the navigation system has a computing unit for distorting the information to be displayed on the display device. This distortion is overlaid with the surroudings of the vehicle so that it can be perceived realistically or accurately by the driver or occupant from the driver's or occupant's point of view. Achieved). This distortion is achieved based on the head position ascertained by the transmitter. It is further possible due to distortion to be manually adjusted by the user by operating the appropriate adjustment device. In this way, the user can manually superimpose the information displayed around the vehicle as perceived by him.

  According to a further exemplary embodiment of the invention, the navigation system has a laser projector for projecting data to be displayed on the windshield of the vehicle. In this case, the windshield can have a laser display that is used to visually display a laser beam that hits even better on a normal windshield.

  As an alternative to laser projectors and laser displays, it is also possible for a head-up display to be equipped with graphics from a monitor projected onto the windshield by means of a mirror arrangement.

  According to a further exemplary embodiment of the present invention, the navigation system comprises a mobile navigation device for providing map material for a navigation device (which is permanently mounted on the vehicle). Yes.

  As already mentioned, according to a further exemplary embodiment of the present invention, it is also possible for this mobile navigation device to be used to control an onboard navigation device.

  In accordance with a further exemplary embodiment of the present invention, the mobile navigation device is designed to transmit selected portions of map material stored on the mobile navigation device.

  In this way, in each case, only the currently required part of the digital map is transmitted to the navigation device (mounted on the vehicle), so the amount of data movement can be minimized. In this case, provisions can be made for the transmitted map digital. For example, as a result, the vehicle is located within a section of the map for at least one minute (or at least another user-selectable period), for example, to be a definable size towards the average vehicle speed.

  In accordance with a further exemplary embodiment of the present invention, the navigation system is designed to use a mobile navigation device screen for display data not shown by the MMI. In other words, the screen of the mobile navigation device can be used as an addition to the vehicle's MMI. As an example, a mobile navigation device has a permanently installed navigation device or a piece of software installed on it that is not available to the MMI. For mobile navigation devices, it is therefore possible to supplement the permanently mounted navigation device and MMI in this way.

  In accordance with a further exemplary embodiment of the present invention, a vehicle having a navigation system as described above is specified.

  According to a further exemplary embodiment of the present invention, the navigation system in the vehicle is designed such that the MMI and the navigation device are located at separate positions in the vehicle.

  This allows the data stored and processed in the navigation device to be highly protected from damage, while the MMI does not meet such high security requirements. . It is therefore possible to make a distinction based on data, parts etc. that are safety critical and less safety critical, after which they are housed either in the navigation device or in the MMI.

  This allows costs to be protected during production as it is not necessary to produce less safety critical parts at such high costs.

  According to a further exemplary embodiment of the invention, the use of a navigation system as described above in a vehicle is demonstrated.

  In accordance with a further exemplary embodiment of the present invention, a method for assisting a driver of a vehicle is demonstrated, and a two-way communication link is provided for man-machine interface and navigation for a complex, menu-controlled multifunction vehicle system. It is provided between the devices. In addition, data located at the man-machine interface is operated by a communication link, man-machine interface, and navigation device, which are separate devices designed to communicate with each other over a communication link.

  In accordance with a further exemplary embodiment of the present invention, a program element is disclosed that, when executed on a processor, instructs the processor to perform the steps described above.

  In this case, the computer program element can be part of a piece of software stored on a processor for vehicle management, for example. Similarly, computer program elements can be used in electronic braking aids. In this case, the processor can likewise be the subject of this invention. Further, exemplary embodiments of the present invention have computer program elements that use the invention from the beginning, as well as computer program elements that prompt existing programs to use the latest version of the invention.

  In accordance with a further exemplary embodiment of the present invention, a computer readable medium is disclosed for storing program elements that, when executed on a processor, instructs the processor to perform the steps described above.

  The term “digital map” is also intended to be understood to mean a map for an Advanced Driver Assistance System (ADAS) without any navigation taking place.

  By way of example, the vehicle is a motor vehicle such as a bus or heavy freight vehicle, or else an aircraft such as a rail vehicle, ship, helicopter or airplane.

  Further, for the purposes of this invention, GPS is representative of all Global Satellite Navigation Systems (GNSS) such as GPS, Galileo, GLONASS (Russia), Complex (China), IRNSS etc. (India). Should be pointed out.

  Preferred exemplary embodiments of the invention are described below with reference to the figures.

1 shows a schematic illustration of a navigation system according to an exemplary embodiment of the present invention. 2 shows a schematic illustration of a sensor for sensing the relative position for a driver's head according to an exemplary embodiment of the present invention. 1 shows a vehicle according to an exemplary embodiment of the present invention. 2 shows a flowchart for a method according to an exemplary embodiment of the present invention.

  The illustrations in the figures are schematic and not to scale.

  In the description of the figures that follow, the same reference numerals are used for the same or similar elements.

  FIG. 1 shows a schematic illustration of the components of a navigation system 100 for mounting in a vehicle. The navigation system 100 includes a navigation device 130 and a man-machine interface 140 connected to the navigation device 130 by a communication link 150, and further includes a sensor 201 and a mobile navigation device 160.

  Data to be transmitted by the navigation system 100 is transmitted from the communication unit 122 to, for example, the communication unit 122 to the control device 140 and transmitted from the control device 140 in the form of a CPU. Can be encrypted using. Similarly, the reception data transmitted from the communication unit 122 to the control unit 140 is decrypted by the encryption unit 121. The communication unit 122 has an antenna 123 for data transmission.

  In principle, the navigation device 130 can use the antenna 123 and the communication device 122 to communicate with the MMI 140 wirelessly. In this regard, the MMI 140 has a suitable antenna 141 as well.

  In addition, a separate wireless communication link can be used for communication between the MMI 140 and the navigation device 130, in which case the navigation device 130 is then further connected to an additional communication unit (FIG. 1). (Not shown).

  The MMI 140 includes an input device 126, an audible output device 127, and a graphic output device 128, for example in the form of a monitor.

  The communication link 150 between the MMI and the navigation device 130 can be in either a wired or wireless form. Furthermore, what should be provided beside each other is possible for both wireless and wired connections.

  The input device 126 can be used to make various adjustments to the navigation device 130 and the MMI.

  A visual output device 128 (eg, in the form of a monitor) can be used to output route information. Furthermore, the route information can also be output by the output device 127 that can be heard. The audible output by the output device 127 has the advantage that the driver is less distracted from what is currently happening in the traffic.

  A memory element 124 that is connected to or integrated with the controller 140 stores digital map data (eg, as navigation map data) in the form of data records. By way of example, the memory element 124 further stores additional information about traffic restrictions, infrastructure devices, and the like in conjunction with data records.

  In addition, the driver assistance device 125 is equipped to be supplied with digital map data or other information (eg, sensor or measurement information).

  For the purpose of determining the current vehicle position, the navigation device comprises, for example, a satellite navigation receiver 106, which is designed to receive positioning signals from Galileo satellites or GPS satellites. A navigation module 120. Of course, satellite navigation receivers can also be designed for other satellite navigation devices.

  The satellite navigation receiver 106 is further connected to the control device 140. The navigation module 120 is also connected to the control device 140. In addition, there is a direct connection between the navigation module 120 and the satellite navigation receiver 106. Therefore, it is possible for the GPS signal to be transmitted directly to the CPU 140.

  For example, the sensor system 119 of the navigation system 100 has a direction sensor 107, a distance sensor 108, a handle angle sensor for the purpose of performing more complex navigation because the positioning signal cannot always be received in the central part of the city. 109, a spring range of motion sensor 102, an ESP sensor system 103, and possibly a photodetector 104, for example in the form of a camera. It is also possible for the beam sensor 105 (radar or lidar sensor) to be provided. Further, the sensor system 119 has a speedometer 101.

  Signals from the GPS receiver 106 and from other sensors are handled in the controller 140. The vehicle position confirmed from the signal is adjusted using map matching by road map. The path information thus obtained is transmitted to the MMI 140 and output, for example, on the monitor 128, which can be in the form of a laser display or a head-up display. Further, it may be performed directly at the MMI 140 for signal handling or part of signal handling. If there is an improved piece of evaluation or display software available, for example, it can be loaded into the MMI or installed with a new (replacement) MMI. This allows a quick and inexpensive improvement.

  Furthermore, the system 100 has a sensor 201 in the form of a camera or a laser scanner, for example. This sensor 201 can sense the relative head position of the driver or other occupant with respect to the windshield. This sensor unit 201 is connected to the navigation device 130 or to its calculation unit 140 by means of a data line 202. This connection can be wired or wireless.

  Further, the mobile navigation device 160 having the antenna 161 is defined such that a wireless communication link 162 can be used to communicate with the navigation device 130. Furthermore, it is possible for the mobile communication unit 160 to be connected to a permanently mounted navigation device 130 by means of a data cable.

  The navigation system described above is a complex, menu-controlled, multifunctional vehicle system having a plurality of functional parts. Its separate arrangement and division of man-machine interface 140 and navigation device 130 allows navigation software that is part of a permanently merged driver assistance system to be connected to a portable man-machine interface. In this case, the navigation software remains unchanged, but the man-machine interface can be improved to a short cycle and thus can be more realistic in display. Without omitting the latest graphic display, it is possible to enable a high security standard for navigation software, which is therefore a necessity for driver assistance systems.

  As an example, the MMI has a small screen 128 mounted in front of the center of rotation of the speedometer needle of the vehicle speedometer. Overall, it is possible for MMI to be designed to be significantly smaller than in the case of integrated solutions. This can be particularly advantageous in the event of an accident with regard to possible damage to vision and safety.

  It is further possible to use a single map software instead of the navigation device 120. In this case, route guidance using a man-machine interface is not possible. However, it can be displayed due to current road signs, speed limitations, etc. In this case, route guidance can also be accepted by the mobile navigation device 160.

  The separation of navigation and MMI allows both parts to be developed based on different safety standards. As an example, the MMI can be designed to have a relatively low safety standard, but the navigation device 130 meets the high safety standard. Moreover, both devices can be replaced, installed or repaired independently of each other.

  Furthermore, it is possible for the MMI display device 128 to be in the form of a windshield laser display. In this case, for example, the actual surroundings of the vehicle as perceived by the driver are superimposed on the road map display. In this way, the driver can perceive important information when simply looking through the windshield. As an example, a sensor 201 provided specifically for this purpose confirms the driver's head position relative to the display 128. In this way, this system is as possible as how the information to be presented to the driver (eg in the form of vector graphics) needs to be distorted so that the graphics and reality overlap. Can be confirmed.

  The graphic is preferably a vector graphic rather than a bitmap graphic and projected by a laser or biaxial deflector device so as not to obscure the reality and lower the power requirement. be able to. Therefore, it is possible for retrofitting for projectors and sensors. Furthermore, it is possible for a projector to be integrated in a mobile terminal. As an example, the projector can be integrated into a mobile phone, which is then placed at the appropriate location in the vehicle. For example, a properly adjusted holding device can be equipped for positioning.

  The information displayed on the display device 128 (windshield) is such as the resulting aisle, intersection road, possibly road name, house number, gas station, post box, restaurant, attraction, selected radio channel, and the like Can be known as convenient information.

  Furthermore, it is possible for the safety related information to be superimposed. Thus, by way of example, a laser display can be combined with a position recognition system so that pedestrians, obstacles, or approaching vehicles on a collision path after it has been identified by the appropriate sensor system 119. , Marked in the field of view.

  In addition, it can be shown as required for information that is important to the operation of the vehicle, such as speed, gear, engine speed, tank, temperature, date, time and warning lights. is there. It is then only necessary to ensure an arrangement that does not interfere with the driver.

  The laser display (or laser) can be manually adjusted so that reality and depiction overlap in exact congruence. In this case, a head sensor is not necessary. If that position is not perceived at that time in the viewing direction, the driver adjusts the display by hand to achieve a good overlap between the map from the average head position and reality.

  FIG. 2 shows a head sensor according to an exemplary embodiment of the present invention. As an example, the sensor 201 is in the form of a CCD or CMOS head sensor. For example, an antenna 203 is provided for the purpose of communication with the calculation unit 140. Data lines can also be provided.

  In FIG. 2, the driver's head is indicated by reference numeral 205, and the image area of the image sensed by sensor 201 is encoded by dotted lines 204 and 206.

  As an example, the sensor 201 has a simple stereoscopic infrared digital camera, and almost senses the driver's or passenger's head position and the distance to that head. In this case, the marker can be helpful, for example, in the form of a red dot stabbed on the forehead.

  Using a more manual alignment of the sensed head position, and possibly the projector position with respect to the windshield, the projected map is maintained consistent with reality across a wide range of head movements.

  In a further exemplary embodiment, the head sensor 201 is in the form of a laser scanner (eg, one “off-position” laser scanner). In this case, the infrared laser is not visible to the driver, and scans the inside of the vehicle in a method of confirming the difference in propagation time and the head position of the driver from the direction.

  Conveniently, the driver is less distracted from the front of the road. Furthermore, the illustrated solution allows a conventional display device to be retained. Many different information can be displayed when requested so that the display is not overly detailed and the driver's attention is not overburdened.

  In addition, the driver can have additional functions to be displayed and arranged, and the driver can adjust these displays and arrangements as needed. Some displays can be the same for all drivers (eg, important information such as speed, distance, warning lights). Other settings and displays can be defined based on the driver as a “style”.

  This simple design of the universal display device further means that it can be integrated into a mobile terminal and thus can be modified even for older vehicles. In particular, for example, both the driver and the occupant can each have a dedicated display with different information. This is of particular interest for driving schools.

In today's vehicles, there are two solutions for navigation:
First, there are mobile navigation devices that can be obtained in the vehicle but do not have access to resources available in the vehicle (apart from the power source). There can also be other navigation devices integrated in the vehicle. This means that they can be easily customized to suit the vehicle and that all available information (such as sensors) and input / output options can be accessed. However, permanently mounted and integrated navigation devices are quickly out of date.

  In accordance with a further concept of the invention, the navigation system further includes a mobile navigation device 160.

  FIG. 3 shows a vehicle having a mobile navigation device 160 and having a navigation system as described above, according to an exemplary embodiment of the present invention.

  The vehicle 301, however, has a built-in integrated navigation device 130 that does not have any map material, or map material that is inappropriate or outdated. If the mobile navigation device 160 is now connected, map data is transmitted from the mobile navigation device 160 to the integrated navigation device 130. The transmission is accomplished via a radio interface or by wire.

  In this case, only those details from the map that are relevant to the current driving situation and to the planned route, for example covering the next 10 minutes of driving, are transmitted. Even if the connection to the mobile device is interrupted, these data continue to be stored in the integrated navigation device. This ensures that the data is still available even if the mobile navigation device is not connected.

In this regard, being converted to the data format of the integrated instrument is important for data from mobile navigation instruments. In this regard, there are three suitable ways:
-Complete conversion of the data takes place within the mobile device 160.

This is a flexible deformation.

  The mobile device converts the data into a raw format, and the integrated device 130 converts this raw format into the format used internally.

  -The whole conversion takes place in the integrated instrument 130,140.

This also requires the conversion routine to be able to be retroactively updated to allow customization to suit a new generation of mobile devices.

  Functions not included in the integrated navigation software are additionally displayed (eg, as a second screen or split screen) by the mobile device.

Similarly, a mobile instrument can be used to display its menu, but the integrated navigation device only shows navigation advice. Thus, depending on the mobile instrument used, different additional functions are obtained, and thus an identification choice for each manufacturer of the system.

  If more than one mobile device is used, for example a mobile navigation device and a smartphone with navigation software, then the defined criteria will ensure that the map data is loaded into the integrated navigation device. Used to select. By way of example, such criteria can be common in map data, accuracy, compatibility, etc. When additional functions are displayed on a mobile device, one of the users can decide which functions are displayed on which device, or one system (preferably An integrated system) determines this. This selection of functions is stored, for example (especially when the user selects it) so that it is available again for subsequent use. In this case, the coordination storage device can be identified on the basis of the following.

-Mobile system (ie for each system A, B, C etc. separately),
-Combinations of systems (ie for each combination A + B, B + C, A + C, etc.),
-General additional functions unrelated to the system.

This means, for example, that a special function is not used for any of A, B, or C, or that another special function is always used, or a combination of functions is selected. It is intended to be understood to mean what is done.

  Buffering data from mobile devices Completely current navigation software in an integrated system means that navigation is possible even if there is no current connection to the mobile device. The use of mobile instrument screens for additional information increases the size of the area that can be used for actual navigation on the screen of the integrated navigation device.

  FIG. 4 shows a flowchart for a method according to an exemplary embodiment of the present invention. In step 401, a two-way communication link is provided between the man-machine interface and the navigation device, a complex, menu-controlled multifunction vehicle system. Furthermore, the communication link is installed between the installed navigation device and the mobile navigation device. In step 402, map data is transmitted from a mobile device to an onboard navigation device. In step 403, the map data is buffered in the on-board navigation device. In step 404, the mobile instrument screen is used to display additional information or for functions not covered by the integrated software. Furthermore, additional information can be stored. In step 405, the data located in the MMI is actuated by the associated communication link.

  Further, “comprising”, “having” does not exclude other elements or steps, and “one (a)” or “an” does not exclude a large number. Should be pointed out. Furthermore, it is noted that features or steps described with respect to one of the exemplary embodiments described above can also be used in combination with other features or steps from the other exemplary embodiments described above. It should be. Any reference signs in the claims should not be construed as limiting.
