Abstract

A method for dynamically displaying a predetermined section (215) from a sequence (205) of navigation instructions (210) on a predetermined display area (135) comprises steps of determining a starting point (220) of the section (215) relative to the sequence (205); determining navigation instructions (210) to be displayed that are located in the section (215); determining relative distances (235) of the navigation instructions (210) to be displayed; determining positions of the navigation instructions (210) to be displayed on the display surface (135) based on the starting point (220) and the relative distances (235); and displaying the navigation instructions (210) at the respective specific positions on the display area (135).

Description

The present invention relates to the display of navigation instructions. In particular, the invention relates to the dynamic display of navigation instructions on a display surface.

A motor vehicle includes a navigation system that determines a route on a road network from a current position to a destination point. The route can include a number of road sections, between each of which a predetermined maneuver must be carried out, for example turning or entering or exiting a highway. A maneuver can be visually provided to a person on board the motor vehicle as a navigation instruction on a display surface.

The maneuvers can be displayed on the display surface in such a way that a preceding and/or subsequent maneuver can also be recognized for a current maneuver. The person can also scroll through a list of maneuvers on the route and, for example, find out about the further course of the route. It is important to present the maneuvers in such a way that the person always controls the presentation and there is no doubt about the content of a maneuver or sequence of maneuvers.

The list of maneuvers can be changed automatically, for example if the route is replanned due to a traffic obstacle. Current information can also be included in the list, such as a warning about an object on the road or a danger of a traffic jam. If the list changes while the person is viewing a portion of it, for example by scrolling through the list, the display may be out of date or information or a maneuver may be displayed in the wrong order.

One object underlying the present invention is to provide an improved technique for dynamically displaying navigation instructions of a route on a predetermined display area. The invention solves the problem by means of the subject matter of the independent claims. Subclaims reflect preferred embodiments.

According to a first aspect of the present invention, a method for dynamically displaying a predetermined excerpt from a sequence of navigation instructions on a predetermined display area comprises the steps of determining a starting point of the excerpt relative to the sequence; determining navigation information to be displayed that lies in the section; determining relative distances of the navigation instructions to be displayed; determining positions of the navigation instructions to be displayed on the display area based on the starting point and the relative distances; and displaying the navigation instructions at the specific positions on the display area.

A navigation instruction preferably includes information that is relevant to the movement of a person or a vehicle in a public traffic area. A navigation advice may include route or traffic information or a recommended maneuver to follow a predetermined route or reach a predetermined destination. The navigation advice may also include advice for improved travel, for example an indication of a break to take or an opportunity to service a vehicle in use, for example at a petrol station or a charging station.

The sequence can be stored in a list, for example, in the type of a data field (array) or in the type of a linked list. The sequence of traffic information is preferably dynamic in that its entries can change without user intervention and independently of a display. One or more traffic advisories can be included in or deleted from the sequence. Optionally, a traffic notice can also be changed.

The proposed method can make the excerpt from the sequence dynamic in two aspects at the same time. The first aspect can include the starting point of the section in the sequence and the second aspect can include a change to a navigation instruction in the sequence. This allows a person to scroll through entries in the sequence while a changed entry is automatically inserted, removed or repositioned.

The proposed combination can provide a unified graphical metaphor that can best inform a person about entries in the sequence. The person can navigate better or adapt their navigation to the information. She can absorb information provided to her more quickly, so she doesn't have to pay as much attention to the display. The person can move themselves or a vehicle more safely over a route or through a road with other road users.

The starting point can preferably occupy a variety of positions between two navigation instructions in the sequence. For example, the two navigation instructions have different integers assigned indices, the starting point can include a fractional number between the indices. In one embodiment, the indices of adjacent navigation instructions differ by one. A predetermined number of intermediate levels can be formed between two indices, which can be taken from the starting point. The starting point can also be varied continuously between the indices. It is preferred that the starting point corresponds to one of the navigation instructions or its assigned index when the section is not currently being changed with respect to the sequence, i.e. when the sequence of navigation instructions is not currently being scrolled.

The display area has a predetermined size and the navigation instructions preferably also have predetermined sizes. A number of navigation instructions that can be displayed simultaneously and completely on the display area can be predetermined. This number can depend on a normal distance that neighboring navigation instructions occupy on the display area if the display is currently static, i.e. if neither the starting point of the section is changed nor a navigation instruction is added to or removed from the list.

By transitioning from a first to a second representation, more or less than the predetermined number of navigation instructions can be displayed in the meantime. One or more of the navigation instructions displayed can only be partially on the display area.

It is further preferred that a position of a navigation instruction on the display area is determined along a predetermined curve that extends across the display area. The curve can, for example, comprise a route that runs essentially diagonally across the display area. Deviating from this, the curve can also be curved. The navigation instructions are preferably displayed opaquely, i.e. opaquely, so that a navigation instruction can partially obscure one further back along the curve. With this method of representation, a first navigation reference facing the viewer can be displayed completely and one or more others can be displayed offset and possibly partially hidden behind it. A visual element on a navigation notice can be arranged in such a way that it can be seen even if the navigation notice is partially hidden behind another.

The navigation instructions can be displayed in perspective along the curve. A perspective effect can arise, for example, in that the size of a navigation instruction depends on its position along the curve, with the navigation instruction that faces the viewer furthest being displayed as the largest.

Changing the starting point and/or inserting or deleting an entry can be animated by providing a temporal sequence of views on the display area that can give a viewer the impression of movement or other gradual change of a navigation cue on the display area.

The procedure can be repeated several times. In particular, the method can be run through cyclically at predetermined time intervals, so that a representation of navigation instructions on the display area can be periodically updated.

During multiple runs, the starting point of the section can be changed compared to the sequence. In particular, the starting point of the section can be changed relative to the sequence with respect to a user-controlled input. The input can be made, for example, using a rotary wheel or direction switches.

A transition of the starting point between two indices can take place according to a predetermined course, whereby the change in the starting point close to an index can take place more slowly than far away from it. In this way, a locking point at an index can be simulated. In addition, an acceleration of the change in the starting point compared to the sequence can be determined depending on user input, so that a kinetic effect results as if the sequence had a physical mass that must be accelerated or decelerated in order to set a desired section.

A relative distance between two navigation instructions can also be changed during multiple passes. In the sequence, each navigation instruction can be assigned a distance to an adjacent navigation instruction in a predetermined direction. Changing the spacing can be used in combination with inserting or removing a navigation hint to animate the respective process and thus make it more clear to a user.

In one embodiment, a relative distance of a first navigation instruction to an adjacent second navigation instruction is gradually reduced from a predetermined normal distance to a predetermined minimum distance, before the first navigation hint is deleted from the sequence. Optionally, distances on both sides can also be adjusted or animated accordingly. The minimum distance can be zero or another predetermined dimension. In this way, removing or hiding the navigation information from the section can be designed to be simple and visually appealing.

In a further embodiment, a navigation cue is inserted into the sequence while its relative distance to an adjacent navigation cue corresponds to a predetermined minimum distance; and the distance is then gradually increased to a predetermined normal distance. Here too, distances on both sides can be adjusted or animated accordingly. The minimum distance can be zero or another predetermined dimension. Adding or displaying the navigation information in the section can be made simple and visually appealing in this way.

In the case of insertion or removal, a visibility of the displayed navigation hint can be gradually changed depending on the relative distance. In a first embodiment, the visibility can be changed from a low to a high value (or vice versa) when the distance exceeds (or falls below) a predetermined threshold value. In a second embodiment, the visibility can be determined in a number of stages or even continuously depending on the relative distance. A relationship between the distance and the visibility can follow a predetermined curve or table or a predetermined relationship. The visibility can be represented, for example, in the form of an opacity, a brightness, a contrast and/or a color.

The sequence can be determined depending on route planning between two geographical positions. The route planning can start from a predetermined route network and determine a number of route sections between a current position or a predetermined starting position and a predetermined destination position. A navigation advice can concern a maneuver between two route sections or dynamic information relevant to movement on the route.

According to a second aspect of the present invention, a device for dynamically displaying a predetermined section of a sequence of navigation instructions comprises a display device with a display area; a storage device for storing the sequence of navigation instructions; and a processing facility. The processing device is set up to determine a starting point of the section relative to the sequence; to determine navigation instructions to be displayed that are located in the section; to determine relative distances of the navigation instructions to be displayed; determine positions of the navigation instructions to be displayed on the display area based on the starting point and the relative distances; and to display the navigation instructions to be displayed at the respective specific positions on the display area using the display device.

The processing device can be set up to carry out a method described herein in whole or in part. For this purpose, the processing device can be designed electronically and include, for example, an integrated circuit or a programmable microcomputer or microcontroller. The method can be in the form of a computer program product with program code means and optionally stored on a computer-readable data carrier. Features or advantages of the method can be transferred to the device or vice versa.

The device can include a control element for user-controlled control of the starting point of the section relative to the sequence. The control element preferably comprises a rotary wheel, which more preferably has a mechanical grid or can be controlled to show the mechanical grid.

According to a further aspect of the present invention, a navigation system includes an apparatus for determining a sequence of navigation instructions and an apparatus described herein. The first-mentioned device can determine the navigation instructions regarding route planning between two geographical positions and optionally regarding a route network. The navigation system can be carried by one person and can be implemented, for example, using an appropriately programmed smartphone. Alternatively, the navigation system is intended for installation on board a vehicle, in particular a motor vehicle.

According to yet another aspect of the invention, a motor vehicle includes a navigation system described herein. The motor vehicle can include, for example, a passenger car, a truck, a motorcycle or a bus.

illustriert.The invention will now be described in more detail with reference to the accompanying drawings, in which:

• 1 a system;
• 2 a sequence of navigation instructions and a corresponding representation of navigation instructions of a section; and
• 3 exemplary sequences of representations of navigation instructions

illustrated.

1 shows a system 100 with a vehicle 105 and a navigation system 110, which can be provided independently or on board the vehicle 105. The navigation system 110 includes a positioning device 115, a processing device 120, a storage device 125, an optical display device 130 with a predetermined display area 135 and an optional control element 140.

The positioning device 115 is set up to determine a geographical position of the navigation system 110. For this purpose, the positioning device 115 can in particular include a receiver for signals from a satellite-based navigation system GNSS, for example GALILEO, GPS, GLONASS or BeiDou. Using the processing device 120, a route from the specific position to a predetermined target position can be found with respect to a road network. The road network can be stored in the storage device 125 or a dedicated storage device. The route comprises a sequence of road sections, between each of which a maneuver can be determined in order to follow the route. Using the positioning device 115 or a dedicated receiver, dynamic information can be determined that can influence the route, its travel or the creation of an alternative route. Such information can be received, for example, via RDS or mobile communications. A sequence of maneuvers and/or information can be stored in the storage device 115.

The display device 130 is preferably graphically capable and the two-dimensional display area 135 has a predetermined size. In different embodiments, the display device can be set up to display single-color or multi-color content. In one embodiment, the display device 130 is included in a display system on board the vehicle 105 and can, for example, be mounted in a center console or be designed as a projector or head-up display for a person on board the vehicle 105.

The control element 140 can be provided, for example, in the form of a touch-sensitive screen or an arrangement of switches or buttons. In a preferred embodiment, the control element 140 comprises a mechanically movable element such as a rotary wheel or a rotary knob. To control the device 110 by a user, another control element 140 can also be provided.

The processing device 120 is set up to display navigation instructions that are in a predetermined section of the sequence of navigation instructions on the display area 135. It is proposed that the representation takes place dynamically with respect to a particularly user-controlled position of the section in the sequence and/or dynamically with respect to a change in a navigation instruction. The change preferably includes inserting or removing a navigation hint from the sequence.

2 shows a schematic representation 200 of an exemplary sequence 205 of navigation instructions 210, for example to follow a predetermined route from a starting point to a destination point, and a corresponding representation of one of the navigation instructions 210 on the display surface 135 of the display device 130.

The sequence 205 in 2 exemplifies a sequence from top to bottom. With regard to the sequence 205, a section 215 is determined which has a predetermined size of navigation instructions 210, in the present case three navigation instructions 210. A position of the section 215 with respect to the sequence 205 is determined by a starting point 220. Each navigation cue may be associated with an index and the starting point 220 may correspond to one of the indexes. The section 215 can be moved vertically with respect to the sequence 205 by moving the starting point 220 from one navigation indication 210 to the next or setting it from one index to the next. Optionally, the starting point 220 can also have a predetermined value or one of several predetermined values between two navigation instructions 210 or their indices.

The three navigation instructions 210 in the section 215 are each assigned a representation 225 on the display area 135. The representations 225 are positioned along a predetermined curve 230, which in the present case comprises a straight line that runs essentially diagonally across the display surface 135. Other exemplary shapes for curve 230 include a circular segment, a parabolic load, or a hyperbolic load. A distance between a representation 225 and an adjacent one is called a relative distance 235 determined. A distance 235 can be stored in the navigation note 210 in the sequence 205.

The representations 220 may partially overlap each other on the display area 135, such that one representation 225 may be partially obscured by another. In the present illustration, the representations 220 are all shown the same size, but in another embodiment different sizes can also be selected, in particular to achieve a perspective effect.

In front of and behind the three representations 220 of the navigation instructions 210, a further representation 225 is indicated by broken lines, one or both of which can be temporarily displayed in some embodiments.

If the starting point 220 is shifted relative to the sequence 205, the representations follow the shift. If the starting point 220 is moved, for example, from a first navigation instruction 210 to a second, a representation 225 of the first, an adjacent second and an adjacent third navigation instruction 210 can be displayed beforehand; During and after the movement, representations 225 of the second, the third and a fourth navigation note 210 adjacent to it can be displayed. If the starting point 220 is moved by only a fraction of it, positions of the displayed representations 225 on the display area 135 can be moved. At least temporarily, a further representation 225 of a navigation instruction 210 partially encompassed by the section 215 can be displayed.

An index can be assigned to a representation 225 or a navigation reference 210 in the section 215. In an exemplary embodiment, the front representation 225 is assigned index 0, the one behind it is assigned index 1 and the rearmost representation 225 is assigned index 2. If a representation is to be displayed further forward, the index -1 can be assigned to it. In a corresponding manner, index 4 can be assigned to a representation that lies even further back. Other assignments are also possible and the representation can also be expanded to a two-dimensional arrangement.

The starting point 220 of the section 215 can be set to a navigation instruction 210 or its index or a value between two navigation instructions 210 or indices. In general, the starting point 220 lies at an index when not scrolling and may have a value between two indexes while scrolling. For example, if navigation instructions 220 are provided with indices 0, 1, 2, 3, 4 and 5, the starting point 220 can temporarily be 1.5.

• - Der Navigationshinweis 210 mit Index 0 ist an der Position -1,5, also nicht sichtbar.
• - Der Navigationshinweis 210 mit Index 1 ist an der Position -0,5, also vor der üblicherweise vorderen Position und sichtbar.
• - Der Navigationshinweis 210 mit Index 2 ist an der Position 0,5, also zwischen der üblicherweise vorderen und der mittleren Position.
• - Der Navigationshinweis 210 mit Index 3 ist an der Position 1,5, also zwischen der üblicherweise mittleren und der hinteren Position.
• - Der Navigationshinweis 210 mit Index 4 ist an der Position 2,5, also hinter der üblicherweise hinteren Position.
• - Der Navigationshinweis 210 mit Index 5 ist an der Position 3,5, also nicht sichtbar.

Then the navigation instructions 225 are displayed as follows:

• - The navigation note 210 with index 0 is at position -1.5, i.e. not visible.
• - The navigation note 210 with index 1 is at position -0.5, i.e. in front of the usually front position and is visible.
• - The navigation note 210 with index 2 is at position 0.5, i.e. between the usually front and middle positions.
• - The navigation note 210 with index 3 is at position 1.5, i.e. between the usually middle and rear positions.
• - The navigation note 210 with index 4 is at position 2.5, i.e. behind the usual rear position.
• - The navigation note 210 with index 5 is at position 3.5, i.e. not visible.

An animation can be done by displaying (frames) the representations 225 on the display area 135 in predetermined time steps. Time intervals between successive frames are preferably the same. In each frame, the starting position 220 of the section 215 and positions of the representations 225 on the display area 135 can be determined. The display is then carried out accordingly.

If a navigation instruction 210 that lies outside the section 215 is changed, the change is not reflected on the display area 135. However, an index of a navigation information 225 located in the section 215 can be adjusted.

If a navigation hint 210 is inserted that lies before the section 215 (with regard to the display of corresponding representations 225), it receives an index and indices following it are incremented. The starting position 220 is also incremented. In the example above, the new navigation hint 210 receives the index 0, the index of the navigation hint 225 that follows it is incremented from 0 to 1 and so on. The navigation instructions 225 of the section 215 then have the indices 1 to 6.

If a navigation note 210 is inserted after section 215, the indices of all navigation notes following it change 225. The indices of the navigation instructions 225 shown and of all those further ahead remain unchanged.

If a navigation note 210 that is in section 215 or whose representation 225 is shown on the display area 135 is changed, more complex transitions can take place. To explain this, the above example is continued with navigation instructions 220 with indices 0 to 5 and a current starting value 220 of 1.5 and a desired starting value 220 of 2.

Before the navigation note 210 with index 2, a new navigation note 210 with index 2 is now inserted into the sequence 205. Immediately after insertion, the new navigation instruction 210 has an opacity of 0 and a distance 235 of zero to the subsequent navigation instruction 210. Subsequent times are determined with respect to the insertion of the new navigation instruction 210 in the sequence 205. In the following, reference will be made synonymously to navigation instructions 210 and their respective representations 225 due to their described pairwise correspondence.

In addition to the distance 235 to an adjacent navigation instruction 220, other properties can be assigned to a navigation instruction 220, for example a current opacity, a desired opacity, which is 1 here, and a desired distance 235, which is also 1 here. An opacity of 1 can correspond to normal visibility and a distance of 235 of 1 can correspond to normal distance.

Scrolling around an entire navigation message 210 may require a predetermined time of, for example, 1 s, so that scrolling the current starting point 220 to the desired starting point takes 0.5 seconds. Animating the distance 235 and/or visibility of the new navigation information 210 occurs simultaneously and may require a further predetermined time of, for example, also 1 s. If the distance 235 of the new navigation information 210 to an adjacent navigation information 220 is increased as part of the animation, the desired starting point 220 can also be adjusted because the navigation information 220 to which scrolling is already known.

3 shows exemplary sequences of representations of navigation instructions 210 or their graphic representations 225. In an upper line 305 there is a change in the starting point 220, in a middle line 310 there is an insertion of a navigation instruction 210 into the sequence 205 and in a lower line 315 a combination of the Both processes are shown schematically. In each line 305-315, several representations of representations 225 are shown on the display area 135 in a temporal sequence from left to right. Purely by way of example, each line 305-315 contains five representations, of which the one furthest to the left represents a starting position and the one furthest to the right represents an end position. The vertical extent of the display area 135 is indicated schematically as an area between two broken lines.

It should be noted that the representations in lines 305-315 are chosen purely as examples and do not necessarily correspond to any other example mentioned herein.

In the first line 305, the section 215 is shifted upwards with respect to the represented representations 225, so that the initially displayed representations 225 are shifted downwards on the display area 135. A new representation 225 appears at the top, in the background. The four representations 225 are successively pushed down until the fourth representation 225 lies completely on the display area 135, even if it may be partially covered by another representation 225. The frontmost representation can then be removed from the display on the display area 135.

In the second line 310, the section 215 stands still compared to the sequence 205. Between the representations 225, which are initially shown at the front and immediately behind them, a further representation 225 is inserted, which is in 2 is marked with a dark color and represents a navigation note 210 inserted into the sequence 205 at the appropriate location. The further representation 225 can initially have a small distance 235 from the front representation 225. The distance 235 can be increased to a normal distance, with the new navigation information 210 and those shown behind it being able to be pushed further back or up on the display area 135. In a penultimate step, three representations 225 are again completely displayed on the display area 135. A representation 225 that is only partially displayed can be removed from the display in a final step.

It should be noted that removing a representation 225 from the display area 135 or a navigation note 210 from the sequence 205 can be carried out in steps that run from right to left in the second line 310.

In the third line 315, the operations of the first line 305 and the second line 310 are combined with one another. Note that simultaneous scrolling and removal of a navigation prompt 225 may be formed from a combination of the first line 305 with a second line 310 flipped in its horizontal direction. The scrolling of the first line 305 is in a first direction; the reverse direction can be visualized by reversing the order of their representations.
