Description

NAVIGATION SYSTEM FOR A COMPLEX, MENU-CONTROLLED, MULTIFUNCTIONAL VEHICLE SYSTEM

The present invention relates to navigation engineering for vehicles. In particular, the present invention relates to navigation systems for complex menu-controlled multifunctional vehicle systems, vehicles with such navigation systems, use of such navigation systems in vehicles, methods for assisting drivers of vehicles, program elements and computer-readings. Relates to a possible medium.

Conventionally, functional components in a vehicle, such as an onboard computer, an air-conditioning system, a radio, a navigation system, and the like, are installed in a vehicle as separate components that can be operated separately. Each individual component has a dedicated operator control panel, which means that the driver needs to be directed to or looking for an operator control element in order to operate the individual components during operation. Often, this distracts the driver from what is happening during the passage.

In addition, selected operator control elements for the individual components, such as accepting calls to the mobile phone, volume control for the radio and program selection keys, are within the reach of the driver, in particular close to the steering wheel or the steering wheel itself. It may be arranged physically apart from the individual components on itself. However, often this makes sense only if the vehicle is to first fit out. In addition, the outlay is relatively high.

In addition, the individual components can be combined to form a complex menu-controlled multifunctional vehicle system. In this case, operator control is concentrated on the operator control interface of the multifunctional vehicle system. By way of example, such a versatility system is installed in the area of a conventional radio installation slot and combines the functions of an onboard computer, air-conditioning system, radio and navigation device. The display of the versatility system may be in the form of a sensed input screen (touch screen display) to allow menu items to be entered by touching the display. Alternatively, operator control elements can be arranged directly adjacent to the display.

The increasing complexity of such menu-controlled multifunctional vehicle systems requires the user to be directed directly to the operator control interface for operator control, and thus includes the risk of distraction from driving.

In general, navigation devices are both a real navigation (map, map matching, routing, etc.) to be combined in one device and a human-machine interface (which is responsible for the presentation of user inputs, ie graphical and audible output of information). It includes.

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

The present invention specifies a complex menu-controlled multifunctional vehicle system, a navigation system for a vehicle, use, method, program element and computer-readable medium, according to the characteristics of the independent claims. The development of the invention can be found in the dependent claims.

The illustrative embodiments described relate to navigation systems, vehicles, uses, methods, program elements, and computer-readable media in equivalent quantities.

According to one exemplary embodiment of the present invention, a navigation system for a complex menu-controlled multifunctional vehicle system is specified, wherein the navigation system comprises a navigation unit, a human-machine interface (MMI or HMI) and a communication link. Has The communication link is designed to provide two-way communication between the person-machine interface and the navigation unit, and the person-machine interface and the navigation unit are separate units designed to communicate with each other via the communication link.

Two units (MMI and navigation unit) are housed in separate appliances. According to another exemplary embodiment of the invention, the human-machine interface and the navigation unit are designed to be arranged in separate positions of the vehicle. Thus, this separate design allows vehicle navigation and MMI to be deployed and installed separately in the vehicle. In particular, this allows both devices to fit at different locations of the vehicle.

By way of example, the human-machine interface is installed in the field of vision of the driver and the navigation portion (navigation unit) is installed in the glove box of the vehicle.

According to another exemplary embodiment of the invention, the navigation unit is designed for mobile communication with a human-machine interface via a communication link. Thus, both units can be connected by cable or by radio. This connection is used to exchange only each of the required data.

Wireless transmission between the MMI and the navigation unit (and the navigation unit and the MMI) is achieved by, for example, WLAN (eg, 802.11p), Bluetooth, ZigBee or WiMax.

According to another exemplary embodiment of the invention, the navigation system is designed to transmit information from the navigation unit to the person-machine interface to evaluate data located at the person-machine interface.

As an example, the MMI has a dedicated computing unit and dedicated data memory. Thus, it is possible that the information to be provided is processed within the MMI. The manner in which this information is processed or provided can be controlled and inspected, for example, by the navigation unit.

According to another exemplary embodiment of the invention, the navigation unit is a module of a driver assistance system. If the text below refers to a "navigation unit", this may be combined with a simple navigation module (see 120 in FIG. 1) or possibly a driver assistance system (see 125 in FIG. 1). It is intended to be understood as meaning a complex system (see reference numeral 130 of FIG. 1) with both a navigation module and appropriate computing units and sensor systems.

According to another exemplary embodiment of the invention, the human-machine interface is designed to be partially integrated into the windshield of the vehicle or in front of the speed instrument panel of the vehicle. In this case, for example, graphical information is displayed on the windshield. The audible output may be provided by a loudspeaker arranged at any position. For example, control commands are input by using voice control, or a mechanical input device arranged on the vehicle's central console or integrated into mobile equipment (PDAs, mobile phones, etc.).

This allows the driver to record graphical information without distracting from what often happens during the passage.

According to another exemplary embodiment of the invention, the navigation system also has a sensor device for checking the head position relative to the driver or passenger with respect to the display unit of the human-machine interface.

According to another exemplary embodiment of the invention, the navigation system has a calculation unit for distorting the information to be displayed on the display unit. The distortion is achieved such that the information to be displayed is overlaid with the surroundings of the vehicle, as perceived by the driver or passenger realistically or accurately from the driver's or passenger's point of view. The distortion is achieved based on the head position confirmed by the transmitting device. It is also possible for the distortion to be manually adjusted by the user by operating the appropriate alignment device. In this way, the user can manually overlay the displayed information with the surroundings of the vehicle, as perceived by the user in a realistic way.

According to another embodiment of the invention, the navigation system has a laser projector for projecting data to be displayed onto the windshield of the vehicle. In such a case, the windshield may have a laser display which is used to display the impinging laser beam much better visually on the normal windshield.

As an alternative to laser projectors and laser displays, it is also possible to provide a head up display comprising graphics from a monitor projected onto the windshield by a mirror arrangement.

According to another exemplary embodiment of the invention, the navigation system has a mobile navigation unit for providing map material for the navigation unit (permanently installed in the vehicle).

As described above, according to another exemplary embodiment of the present invention, it is possible that such a mobile navigation unit is also used to control the installed navigation unit.

According to another embodiment of the invention, the mobile navigation unit is designed to transmit a selected portion of the map material stored in the mobile navigation unit.

In this way, it is possible to minimize data traffic since in each case only the currently required portion of the digital map is transmitted to the navigation unit (installed in the vehicle). In such a case, the vehicle is located within the map section for at least one minute (or at least during another user-selectable period), for example, as it may provide transmitted map details that are definable size directed to average vehicle speed. .

According to another exemplary embodiment of the present invention, the navigation system is designed to use the screen of the mobile navigation unit to display data not presented by the MMI. That is, the screen of the mobile navigation unit can be used as an addition to the MMI of the vehicle. By way of example, a mobile navigation unit has a piece of software installed on the mobile navigation that is not permanently installed on the navigation unit or MMI. Thus, it is possible for the mobile navigation unit to supplement the permanently installed navigation unit and MMI in this way.

According to another exemplary embodiment of the invention, a vehicle having a navigation system as described above is specified.

According to another exemplary embodiment of the invention, the in-vehicle navigation system is designed such that the MMI and the navigation unit are arranged at separate locations in the vehicle.

This allows the data stored and processed in the navigation unit to a high degree of protection from damage, but the MMI does not meet such high safety requirements. Thus, it is possible to distinguish based on safety-critical and less safety-critical data, components, etc., and then the data, components, etc. are accommodated in either the navigation unit or the MMI.

Since less safety-critical components do not have to be manufactured at such a high cost, this allows for cost savings during manufacturing.

According to another exemplary embodiment of the invention, the use of navigation in a vehicle as described above is specified.

According to another exemplary embodiment of the present invention, a method for assisting a driver of a vehicle is specified, in which the bidirectional communication between the human-machine interface and the navigation unit for a complex menu-controlled multifunctional vehicle system Links are provided. In addition, data located at the person-machine interface is activated, and the person-machine interface and the navigation unit are separate units designed to communicate with each other via a communication link.

According to another embodiment of the invention, when executed on a processor, a program element is specified that instructs the processor to perform the above-described steps.

In such a case, for example, the computer program element may be part of a piece of software stored on a processor for vehicle management. Similarly, computer program elements can be used in electronic braking assistants. In such a case, the processor may also be a matter of the present invention. In addition, this exemplary embodiment of the present invention includes not only computer program elements which use the rights of the present invention from the beginning, but also computer program elements which allow existing programs to use the present invention by updating.

According to another exemplary embodiment of the present invention, a computer-readable medium is specified that stores program elements that, when executed on a processor, instruct the processor to perform the steps described above.

The term "digital map" is also intended to be understood to mean maps for Advanced Driver Assistance Systems (ADAS) where no navigation is performed.

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

It should also be pointed out that within the context of the present invention, GPS is representative of all global navigation satellite systems (GNSS) such as GPS, Galileo, Glonass (Russia), Complex (China), IRNSS (India) and the like.

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

2 shows a schematic diagram of a sensor for sensing a position relative to the head of a driver based on an exemplary embodiment of the present invention.
3 shows a vehicle based on an exemplary embodiment of the invention.
4 shows a flowchart for a method based on an exemplary embodiment of the invention.

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

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

1 shows a schematic diagram of components of a navigation system 100 for installation in a vehicle. The navigation system 100 has a navigation unit 130 and a person-machine interface 140 connected to the navigation unit 130 via a communication link 150, and also includes a sensor 201 and a mobile navigation unit. Has 160.

For example, data to be transmitted by the navigation system 100, which is transmitted from the control unit 140 in the form of a CPU to the communication unit 122, can be encrypted using the encryption device 121. Similarly, the received 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 unit 130 can use this antenna 123 and the communication device 122 to communicate wirelessly with the MMI 140. For this purpose, the MMI 140 also has a suitable antenna 141.

It is also possible to use a separate wireless communication link for communication between the MMI 140 and the navigation unit 130, in which case the navigation unit 130 is accordingly an additional communication unit (shown in FIG. 1). Is not used).

MMI 140 has an input unit 126, an audible output unit 127, and a graphics output unit 128, for example in the form of a monitor.

The communication link 150 between the MMI and the navigation unit 130 may be either wired or wireless. It is also possible for both wireless and wired connections to be provided around each other.

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

The visible output unit 128 (eg, in the form of a monitor) can be used to output routing information. In addition, routing information may also be output via the audible output unit 127. The output through the audible output unit 127 has the advantage that the driver is less distracted from what is currently occurring during the passage.

Memory element 124 connected to or integrated in control unit 140 stores digital map data (eg, as navigation map data) in the form of data records. By way of example, the memory element 124 also stores additional information regarding pass restrictions, infrastructure devices, and the like, with respect to its data records.

In addition, a driver auxiliary unit 125 is provided that is supplied with digital map data or other information (eg, sensor or measurement information).

To determine the current vehicle position, the navigation unit has a navigation module 120 with a satellite navigation receiver 106 that is designed to receive positioning signals, for example, from a Galileo satellite or a GPS satellite. Of course, the satellite navigation receiver may also be designed for other satellite navigation systems.

The satellite navigation receiver 106 is connected to the control unit 140. In addition, the navigation module 120 is connected to the control unit 140. In addition, there is a direct connection between the navigation module 120 and the satellite navigation receiver 106. Thus, it is possible for GPS signals to be sent directly to the CPU 140.

For example, since positioning signals may not always be received in the center of the city, the sensor system 119 of the navigation system 100 may include a direction sensor 107, a distance sensor 108, steering to perform complex navigation. It also has a wheel angle sensor 109, a spring excursion sensor 102, an ESP sensor system 103, and possibly an optical detector 104, possibly in the form of a camera, for example. It is also possible for the beam sensor 105 (radar or lidar sensor) to be provided. The sensor system 109 also has a speedometer 101.

Signals from the GPS receiver 106 and other sensors are processed at the control unit 140. The vehicle location identified from the signals is aligned using map matching by road maps. For example, routing information obtained in this manner is transmitted to the MMI 140 and output on the monitor 128 (which may also be in the form of a laser display or a head up display). It is also possible that the processing or part of the processing of the signals is performed directly at the MMI 140. For example, if there is an improved piece of evaluation or presentation software available, it can be loaded onto the MMI, or installed with a new (alternative) MMI. This allows for swift and inexpensive improvements.

The system 100 also has a sensor 201 in the form of a camera or laser scanner, for example. The sensor 201 may detect the relative head position of the driver or other position of the passenger relative to the windshield. The sensor unit 201 is connected to the navigation unit 130 or its calculation unit 140 by the data line 202. This connection may be wired or wireless.

Also provided is a mobile navigation unit 160 with an antenna 161 that can use the wireless communication link 162 to communicate with the navigation unit 130. It is also possible for the mobile communication unit 160 to be connected to the navigation unit 130 installed permanently by a data cable.

The above described navigation system is a complex menu-controlled multifunctional vehicle system having a plurality of functional components.

The separate arrangement and separation of the human-machine interface 140 and the navigation unit 130 allows navigation software that is part of the permanently included driver assistance system to be connected to the deliverable human-machine interface. In this case, the navigation software remains unchanged, but the human-machine interface can be improved in a short cycle, thus making it even more realistic in the presentation. Thus, it is possible to allow high safety standards for the navigation software required for driver assistance systems without excluding the latest graphical representation.

As an example, the MMI has a small screen 128 fitted in front of the center of rotation of the speedometer needle of the speed instrument panel of the vehicle. Overall, it is possible for MMI to be designed to be significantly slimmer than for an integrated solution. This may be particularly advantageous with regard to possible damage to vision and safety in accident events.

Instead of the navigation device 120, it is also possible to use a piece of map software. In this case, route guidance through the human-machine interface is not possible. However, it is possible for the current load sine, speed limit, etc. to be displayed. In this case, the mobile navigation device 160 can take care of route guidance.

The separation of navigation and MMI allows both components to be developed based on different safety criteria. As an example, the MMI may be designed to have a relatively low safety standard, but the navigation unit 130 meets the high safety standard. In addition, both units may be replaced, serviced or repaired independently of each other.

It is also possible that the display device 128 of the MMI is in the form of a windshield laser display. In this case, the actual surroundings of the vehicle, for example as perceived by the driver, are overlaid with the presentation of the road map. In this way, the driver can sense important information simply by looking through the windshield. As an example, the sensor 201, which is provided in particular for this purpose, confirms the head position of the driver with respect to the display 128. In this way, the system can identify 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 the entity overlap as well as possible.

In order to keep the power requirements low without obscuring the reality, it is preferred that the graphic is a vector graphic rather than a bitmap graphic, as can be projected by a laser or biaxial deflector unit. Thus, it is possible to improve the projector and the sensor. It is also possible for the projector to be integrated into the mobile terminal. By way of example, the projector may be integrated into a mobile phone, which is then located at an appropriate location in the vehicle. For example, a properly aligned support device may be provided for positioning.

The information presented on display device 128 (windshield) is known as convenient information such as the route to take, the intersection, possibly the load name, house number, gas station, mailbox, restaurant, attractive place, selected radio channel, etc. It may also include.

It is also possible for safety-related information to be overlaid. Thus, as an example, the laser display can be combined with a location-finding system such that a pedestrian, obstacle or approaching vehicle on a collision route is marked in view after being identified by the appropriate sensor system 119.

It is also possible to indicate, as required, information important to the operation of the vehicle, such as speed, gear, engine speed, tank, temperature, time, and warning lamp. After that, it is only necessary to ensure an arrangement that does not disturb the driver.

The laser display (or laser) can be manually adjusted such that the entity and description overlap exactly exactly. In this case, no head sensor is required. If the position is not detected in the eye's field of view, the driver adjusts the display by hand to achieve a good overlap between the map and the entity from the average head position.

2 shows a head sensor based on an exemplary embodiment of the present invention. By way of example, sensor 201 is in the form of a CCD or CMOS head sensor. For example, for communication with the calculation unit 140, an antenna 203 is provided. In addition, a data line may be provided.

In FIG. 2, the head of the driver is indicated by reference 205, and the image area of the image sensed by detector 201 is symbolized by dashed lines 204 and 206.

By way of example, sensor 201 includes a simple stereoscopic infrared digital camera, which essentially senses the head position of the driver and passenger and the distance to the head. In such cases, for example, a marker in the form of a red dot fixed on the forehead may be useful.

Using additional manual alignment of the sensed head position and possibly the position of the projector relative to the windshield, the projected map remains consistent with the entity over a wide range of head movements.

In yet another exemplary embodiment, the head sensor 201 is in the form of a laser scanner (eg, in the form of an “off position” laser scanner). In this case, the infrared laser scans the interior of the vehicle in a manner that is not visible to the driver and checks the driver's head position from the propagation time difference and direction.

Advantageously, the driver's attention due to the road ahead is less distracting. The illustrated solution also allows for saving conventional display mechanisms. Many different information can be presented when the display is not required to be overloaded with details and thus the driver's attention may not be overused.

In addition, the driver may have additional functions that are displayed and arranged, and may adjust these displays and arrangements as needed. The particular display (eg, important information such as speed, distance, warning lamp) may be the same for all drivers. Other settings and displays can be defined as "style" based on the driver.

The simple design of such a universal display mechanism also means that the mechanism can be integrated into a mobile terminal and thus can be retrofitted for older vehicles. In particular, both the driver and the passenger may each be provided with a dedicated display containing different information, for example. In particular, this is of interest in driving schools.

In today's vehicles, there are two solutions for navigation, first of all there are mobile navigation devices that can be taken in the vehicle but cannot access the resources available in the vehicle (off the power). There may also be other navigation devices integrated into the vehicle. This means that they can be easily customized to fit the vehicle and have access to all available information (such as sensors) and input / output options. However, these permanently installed and integrated navigation devices are rapidly becoming outdated.

According to another aspect of the invention, the navigation system also has a mobile navigation device 160.

3 shows a vehicle based on an exemplary embodiment of the present invention having a navigation system as described above including a mobile navigation device 160.

However, the vehicle 301 has a built-in integrated navigation unit 130 that does not have any map material or inappropriate or outdated map material. When the mobile navigation device 160 is currently connected, map data is transmitted from the mobile navigation device 160 to the integrated navigation unit 130. The transmission is accomplished over the air interface or over the wire.

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

In this regard, it is important that the data from the mobile navigation device be converted into the data format of the integrated device. There are three suitable ways to do this.

The complete conversion of the data takes place at the mobile device 160.

This is a flexible variant.

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

The whole transformation takes place in the integrated device (130, 140). This requires conversion routines for the customization to be updated very retroactively to make it suitable for new generations of mobile devices.

Functions not included in the integrated navigation software are additionally presented by the mobile device (eg, as a second screen or a separate screen). Similarly, a mobile device can be used to present a menu, but the integrated navigation system represents only the navigation device. Thus, depending on the mobile device used, different additional functions and thus differentiation options for each manufacturer of the system are obtained.

When a smartphone with a plurality of mobile devices, for example a mobile navigation device and navigation software, is used, defined criteria are used to select which map data is loaded into the integrated navigation unit. By way of example, such criteria may be the currentness, accuracy, compatibility, etc. of the map data. When additional functions are presented on the mobile device, the user can determine which function will be presented on which device, or one of the systems (preferably an integrated system) determines this. This function selection is stored, for example, again available for future use (especially if the user selects it). In this case, the storage of the configuration can be distinguished based on the following.

Mobile systems (i.e. separate for each system A, B, C, etc.),

Combination of systems (ie for each bond A + B, B + C, A + C, etc.),

General add-ons independent of the system. This is intended to be understood, for example, to mean that a particular function is not used for A, or B or C, another particular function is always used, or a combination of functions is selected.

The buffering of data from the mobile device and the complete current navigation software in the integrated system means that navigation is possible even if no connection to the mobile device currently exists. The use of the screen of the mobile device for additional information increases the size of the area that can be used for actual navigation on the screen of the integrated navigation unit.

4 shows a flowchart for a method based on an exemplary embodiment of the invention. In step 401, a bidirectional communication link is provided between the human-machine interface and the navigation unit for a complex menu-controlled multifunctional vehicle system. In addition, the communication link is set up between the installed navigation unit and the mobile navigation unit. In step 402, map data is transmitted from the mobile device to the navigation unit installed. In step 403, map data is buffered in the installed navigation unit. In step 404, the screen of the mobile device is used for presenting additional information or for functions not covered by the integrated software. In addition, additional information may be stored. At step 405, data located in the MMI is activated over the associated communication link.

It should also be pointed out that "comprising" and "having" do not exclude other elements or steps, and "a" or "an" does not exclude a plurality. . In addition, it should be pointed out that the features or steps described with reference to one of the example embodiments can also be used in combination with other features or steps from the other example embodiments described above. Reference signs in the claims should not be considered as limiting.
