detailed description

Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

Please refer to FIG. 1 and FIG. 2 , the display method according to the embodiment of the present invention is used in a vehicle-mounted terminal 100 . The vehicle-mounted terminal 100 is installed in a vehicle. Display methods include:

S12: When the lane-level data of the map and the environment data of the current road where the vehicle is located are obtained, an environment simulation display screen is generated according to the lane-level data and the environment data, and several lanes corresponding to the current road are displayed on the environment simulation display screen;

S14: Determine the display angle of the marking panel according to the map state and the driver's line of sight information;

S16: Fusing the labeling panel with the environment simulation display screen to generate a navigation simulation display screen.

The display method in the embodiment of the present invention can be implemented by the vehicle-mounted terminal 100 in the embodiment of the present invention. Specifically, the vehicle-mounted terminal 100 is installed in a vehicle. The vehicle-mounted terminal 100 is used for: in the case of obtaining the lane-level data of the map and the environment data of the current road where the vehicle is located, generate an environment simulation display screen according to the lane-level data and the environment data, and the environment simulation display screen displays the information corresponding to the current road. several lanes; determine the display angle of the marking panel according to the map state and the driver's sight information; integrate the marking panel and the environment simulation display screen to generate a navigation simulation display screen.

In the above display method and vehicle-mounted terminal 100, the display angle of the labeling panel is determined according to the map state and the driver's line of sight information. Therefore, the user can see the information on the labeling panel more conveniently and effectively by viewing the navigation simulation display screen, In this way, users can find potential problems in time through the labeling panel and improve driving safety.

It can be understood that in related technologies, the vehicle can provide a navigation screen for navigation, and the angle of the labeling panel displayed in the navigation screen is always facing the display screen. Although this ensures the readability of the information to a certain extent, it does not The angle of the marking panel does not combine the actual positional relationship between the cockpit and the driver. When the display screen is not facing the driver, the marking panel in the display screen viewed by the driver will produce perspective distortion, which makes it difficult to read correctly Issues such as the display content of the labeling panel.

In the display method of the embodiment of the present invention, the display angle of the labeling panel is determined according to the map state and the driver's line of sight information in consideration of the cockpit layout and the driver's actual position, and the display angle of the labeling panel is dynamically adjusted, thereby compensating the display angle. The perspective distortion formed by the angle of the screen and the user's line of sight makes it easier for the driver to quickly and accurately read the displayed content of the labeling panel, making driving safer. In addition, dynamically adjusting the display angle of the labeling panel can make the information display on the navigation simulation display screen more flexible and targeted. Moreover, through the change of the display angle of the labeling panel, the displayed navigation simulation display screen has a more sense of space, which is conducive to improving user experience.

Specifically, in some implementations, the vehicle-mounted terminal 100 may include one or more processors 10 and a memory 20, and the memory 20 stores a computer program. When the computer program is executed by the processor 10, the embodiment of the present invention can be implemented. display method.

In step S12, the map may be a high-precision map provided by the supplier. Maps can include lane-level data, place names, house buildings, natural landscapes, and more. Lane-level data may include lane data, tunnel data, bridge data, guardrail data, and the like. The map can be stored in the cloud server or in the memory 20 of the local vehicle terminal 100, which is not limited here. In some embodiments, the map is stored in the cloud server, and the vehicle terminal 100 can connect to the cloud server through wireless communication (such as WIFI, mobile communication network, etc.), and then the vehicle terminal 100 obtains the lane-level data of the map from the cloud server. In some implementations, the map is stored in the memory 20 of the local vehicle-mounted terminal 100 , and the processor 10 of the vehicle-mounted terminal 100 obtains the lane-level data of the map from the memory 20 of the vehicle-mounted terminal 100 . It can be understood that the lane-level data of the map is static, while the environment data is dynamic.

Vehicles may include environment awareness sensors. Environmental perception sensors can include high-definition cameras, millimeter-wave radars, ultrasonic radars, laser radars, attitude sensors, positioning sensors, etc. Environmental awareness sensors can be placed around the vehicle. Environmental perception sensors can acquire dynamic environmental data around the vehicle in real time. The environmental data of the vehicle may include nearby pedestrians, location information of nearby pedestrians, nearby vehicles, location information of nearby vehicles, and the like. By processing the electrical signals generated by the environment awareness sensors, it is possible to obtain the environmental data of the vehicle. Further, in step S12, an environment simulation display screen may be generated by fusing the lane-level data and the environment data.

In step S14, the map state may include an activated state and an immersed state. It can be understood that the activated state and the immersed state are two relative states. When the map state is in the immersed state, some unnecessary information will be hidden in the display screen of the map. Information and/or low-frequency operation buttons (such as setting buttons and search entries), so that more space can be used to display the map itself; relatively, when the map status is activated, the display screen of the map is richer, and the map The display screen includes some unnecessary information and/or low-frequency operation buttons that are hidden in the immersive state, so as to facilitate user operations. The driver can include the main driver who is in the main driver and the co-pilot who is in the second driver. The gaze information may include looking towards the display screen and not looking towards the display screen. In some embodiments, the line of sight information can be determined through the DSM in combination with the layout of the cockpit, and the DSM can be installed on the steering column of the steering wheel, or on the A-pillar of the vehicle.

The labeling panel can be understood as a prompt label. In some embodiments, the marking panel is bound to the road surface in the environment simulation display screen, and the marking panel includes latitude and longitude information and height information of the road surface. The labeling panel can include labeling style, labeling position, labeling type and display angle. The labeling style can be understood as the display effect of the labeling panel, such as highlighting, highlighting, etc. The marking position can be understood as the latitude and longitude information and height information of the road surface corresponding to the marking panel. The type of labeling can be understood as the display content of the labeling panel. The display angle of the labeling panel can be automatically determined according to the driver's sight angle when looking at the display screen, and the display angle of the labeling panel can also be customized and set by the driver in advance, which is not limited here. The display angle of the labeling panel may include facing the display screen and facing the driver. It can be understood that the display angle of the labeling panel is also related to the layout of the cockpit.

In step S16, the navigation simulation display screen includes a labeling panel and an environment simulation display screen. Integrating the labeling panel with the environment simulation display screen can be understood as binding the labeling panel to the corresponding position of the environment simulation display screen according to the latitude and longitude information and height information. In some implementations, after step S16, the display method further includes: displaying a navigation simulation display screen. In this way, the labeling panel in the displayed navigation simulation display screen has a corresponding display angle. In some implementations, the vehicle-mounted terminal 100 may include a display screen, which can display navigation simulation display images with different display angles; in some implementations, the vehicle includes an imaging device (such as a projector), and the imaging device can display different viewing angles. A navigation simulation display showing the perspective. In some implementations, while the labeling panel is displayed, voice broadcast is performed on the content of the labeling panel, so that the user can learn more about current lane information or current road information in a timely manner.

It should be pointed out that, in some implementations, the navigation simulation display screen further includes the ego model of the vehicle, and the display method further includes: determining the ego model of the vehicle according to the ego state information of the vehicle. The own vehicle status information of the vehicle may include at least one of vehicle light information, vehicle door information, gear position information, control function information, energy status information and system status information. Since the ego model of the vehicle is determined according to the ego state of the vehicle, the user can know the ego state information of the vehicle by viewing the navigation simulation display screen, so that the user can better understand the ego state information when viewing the navigation simulation display screen. The status of the vehicle can be detected in time to detect potential problems and improve driving safety.

Referring to Fig. 3 and Fig. 4, in some embodiments, the vehicle-mounted terminal 100 includes a display screen 200, and step S14 includes:

S1412: When the map state is activated, the labeling panel 202 faces the display screen 200;

S1414: When the state of the map is immersive and the driver's line of sight is looking at the display screen 200, the marking panel 202 faces the driver;

S1416: When the map state is immersive and the driver's line of sight is not looking at the display screen 200, the labeling panel 202 faces the display screen 200;

S1418: When the map state is immersive and the driver's sight cannot be recognized, the marking panel 202 faces the driver.

The display method in the above embodiments can be realized by the vehicle-mounted terminal 100 in the embodiments of the present invention. Specifically, the vehicle-mounted terminal 100 is used to set the labeling panel 202 facing the display screen 200 when the map state is an active state, and to set the labeling panel 202 to face the display screen 200 when the map state is an immersive state and the driver's line of sight is looking at the display screen 200. The marking panel 202 faces the driver, and is used for when the map state is an immersive state and the driver's line of sight is not looking at the display screen 200, the marking panel 202 is facing the display screen 200, and is used for driving when the map state is an immersive state When the driver's line of sight cannot be recognized, the labeling panel 202 faces the driver.

In this way, the display angle of the labeling panel 202 can be determined based on the map state and the driver's line of sight information.

Specifically, when the map state is activated, the display angle of the labeling panel 202 is always facing the display screen 200 no matter whether the driver looks at the display screen 200 or not. It can be understood that under normal circumstances, when the map status is activated, the driver may not start driving the vehicle but is operating the display screen 200. At this time, the driver is usually closer to the display screen 200, and the driver looks at the display screen 200. When the line of sight angle is small, the labeling panel 202 is directly facing the display screen 200, which can better ensure the readability of information. Usually, when the map state is activated, the driver may be focusing on driving the vehicle according to the navigation. At this time, the driver is usually far away from the display screen 200, and the driver's line of sight angle when looking at the display screen 200 is relatively large. The perspective distortion is serious, so when the driver's line of sight is looking at the display screen 200, the labeling panel 202 faces the driver, which helps to compensate for the perspective distortion and ensures the readability of the information. When the screen 200 is displayed, the labeling panel 202 is facing the display screen 200, which is convenient for other passengers to obtain the displayed content of the labeling panel 202. In addition, when the map state is immersive and the driver's line of sight cannot be recognized, the labeling panel 202 always faces the driver, which is beneficial to ensure that the driver can correctly obtain the display content of the labeling panel 202 to ensure driving safety.

Referring to Fig. 5 and Fig. 6, in some embodiments, the vehicle-mounted terminal 100 includes a display screen 200, and the driver includes a main driver and a co-driver, and step S14 includes:

S1422: When the main driver operates the display screen 200 to make the map state enter the active state, the marking panel 202 faces the main driver;

S1424: When the co-pilot operates the display screen 200 to activate the map state, the marking panel 202 faces the co-pilot.

The display method in the above embodiments can be realized by the vehicle-mounted terminal 100 in the embodiments of the present invention. Specifically, the vehicle-mounted terminal 100 is used to make the labeling panel 202 face the main driver when the main driver operates the display screen 200 to make the map state enter the active state, and is used to make the map display 200 to be activated by the co-driver. When the state enters the active state, the labeling panel 202 faces the co-pilot.

In this way, priority is given to ensuring that the operator of the display screen 200 can correctly and quickly understand the displayed content of the labeling panel 202 .

Specifically, the way the map state enters the active state may include opening the map and exiting the immersive state. Ways to exit the immersive state include, but are not limited to, operations such as searching, panning, and zooming while in the immersive state. In some implementations, after the main driver operates the display screen 200 to make the map state enter the active state, the labeling panel 202 always faces the main driver. After the map state enters the immersive state, if the main driver looks at display screen 200, then the labeling panel 202 faces the main driver; if the main driver's line of sight does not look at the display screen 200, then the labeling panel 202 is facing the display screen 200; The marking panel 202 always faces the main driver. Further, if the co-pilot operates the display screen 200 to activate the map state, the subsequent marking panel 202 always faces the co-pilot. Similarly, after the co-pilot operates the display screen 200 to make the map state enter the active state, the marking panel 202 always faces the co-pilot. After the map state enters the immersive state, if the co-pilot looks at the display screen 200 Then the labeling panel 202 faces the co-driver; if the co-pilot's line of sight does not look at the display screen 200, then the labeling panel 202 faces the display screen 200; Facing the co-pilot, further, if the main driver operates the display screen 200 to activate the map state, then the subsequent marking panel 202 always faces the main driver. In some embodiments, when the labeling panel 202 faces the display screen 200, the display angle of the labeling panel 202 is recorded as 0 degrees, and when the labeling panel 202 faces the main driver, the display angle of the labeling panel 202 is a positive number , when the labeling panel 202 faces the co-pilot, the display angle of the labeling panel 202 is a negative number; or, when the labeling panel 202 faces the main driver, the display angle of the labeling panel 202 is a negative number, when the labeling panel 202 faces The display angle of the marking panel 202 is a positive number when the driver is driving.

Referring to Fig. 7, in some embodiments, the driver includes a main driver and a co-pilot, and step S14 includes:

S1432: When the main driver performs map operations through voice commands, the labeling panel faces the main driver;

S1434: When the co-pilot performs map operations through voice commands, the marking panel faces the co-pilot.

The display method in the above embodiments can be realized by the vehicle-mounted terminal 100 in the embodiments of the present invention. Specifically, the vehicle-mounted terminal 100 is used to make the labeling panel face the main driver when the main driver performs map operations through voice commands, and is used to turn the labeling panel For the co-pilot.

In this way, the display angle of the labeling panel can be determined according to the voice command.

Specifically, it can be determined whether the voice command comes from the main driver or the co-pilot by locking the sound zone of the main driver and the co-pilot. Further, in response to the map operation corresponding to the voice command, the labeling panel is faced to the driver who gave the voice command.

Referring to Fig. 8, in some embodiments, the driver includes a main driver and a co-driver, and step S14 includes:

S1442: When the current operator is switched from the main driver to the co-pilot, the marking panel is switched from facing the main driver to facing the co-pilot;

S1444: When the current operator is switched from the co-pilot to the main driver, the marking panel is switched from facing the co-pilot to facing the main driver.

The display method in the above embodiments can be realized by the vehicle-mounted terminal 100 in the embodiments of the present invention. Specifically, the vehicle-mounted terminal 100 is used to switch the current operator from the main driver to the co-pilot, switch the labeling panel from facing the main driver to facing the co-driver, and is used to switch from the co-pilot to the co-pilot when the current operator is For the main driver, the marking panel is switched from facing the co-pilot to facing the main driver.

In this way, the display angle of the labeling panel can be dynamically adjusted according to the current operator.

Specifically, the current operator may include a person who currently operates the display screen and/or a person who currently issues a voice instruction. In some implementations, the person who continues to operate the display screen or issue a voice command within a preset period of time is the current operator. In this way, false triggering is prevented from changing the display angle of the labeling panel.

In one example, the main driver first operates the display screen to make the map state enter the active state, and the labeling panel faces the main driver, and then the co-pilot operates the display screen to make the map state enter the active state. The driver switches to face the co-pilot. In another example, the main driver first operates the display screen to make the map status enter the active state, and the labeling panel faces the main driver, and then the co-pilot performs map operations through voice commands. At this time, the labeling panel will face the main driver. Switch to face the co-pilot. In another example, the co-pilot first performs map operations through voice commands, and the marking panel faces the co-pilot, and then the main driver performs map operations through voice commands. At this time, the marking panel will switch from facing the co-pilot to facing the main driver.

Referring to FIG. 9, in some implementations, before step S14, the display method further includes:

S18: Determine the marking panel according to the state of the current road and the current lane where the vehicle is located.

The display method in the above embodiments can be realized by the vehicle-mounted terminal 100 in the embodiments of the present invention. Specifically, the vehicle-mounted terminal 100 is used to determine the marking panel according to the state of the current road and the current lane where the vehicle is located.

In this way, the user can know the current lane information or current road information of the vehicle by viewing the navigation simulation display screen, which is convenient for the user to better understand the current lane information or current road information through the labeling panel while watching the navigation simulation display screen, and timely Identify potential problems and improve driving safety.

Specifically, the state of the current lane can be understood as a state corresponding to the driving environment of the current lane. The state of the current lane may include approaching or reaching a first preset point, approaching or reaching a first preset road section. The state of the current road can be understood as the state corresponding to the attributes of the road. The current state of the road may include approaching or reaching a second preset point, approaching or reaching a second preset road section. A current road state corresponds to a type of marking panel, and a current lane state also corresponds to a type of marking panel. The first preset point may include turn-by-turn navigation nodes, unexpected car accidents, traffic signs (electronic eye, number limit, speed limit, height limit, prohibition of honking, etc.) and other positions. The second preset point may include starting and ending points of a specific road section, navigation passing locations, changes in administrative districts, changes in road grades, and the like. Specific road sections may include road sections available for lane-level navigation, road sections for general navigation, road sections available for assisted driving, road sections available for automatic driving, dangerous road sections, and speed-limited road sections. Road class changes may include access to interior roads. The first preset road section may include congested road sections, straight lanes, left-turn lanes, tidal lanes, bus lanes, emergency lanes and other road sections. The second preset road section may include road sections such as temporary road changes (road closure, road repair and diversion, road accumulation of water, road collapse, road surface cracking, etc.).

Referring to FIG. 10, in some embodiments, step S18 includes:

S182: In the case that the current driving route of the vehicle includes a preset lane meeting the preset condition, marking the lane corresponding to the preset lane as a marking panel;

S184: In the case that the current driving route of the vehicle includes a preset road that meets the preset condition, label the road corresponding to the preset road as a labeling panel.

The display method in the above embodiments can be realized by the vehicle-mounted terminal 100 in the embodiments of the present invention. Specifically, the vehicle-mounted terminal 100 is used to label the lane corresponding to the preset lane as a labeling panel when the current driving route of the vehicle includes a preset lane that meets the preset conditions, and to use the vehicle's current driving route to In the case of including preset roads that meet the preset conditions, the road marking corresponding to the preset road is used as the marking panel.

In this way, the labeling panel prompts can be provided more accurately, and the labeling panels with low correlation with the driving behavior of the self-vehicle can be filtered, so that the labeling panel prompts are more directional.

Specifically, the current driving route of the vehicle may include the current driving lane and the target lane. The target lane can be understood as the lane that is about to switch to the current driving lane corresponding to the lane-changing intention of the ego vehicle. The lane-changing intention of the ego vehicle may include the lane-changing intention generated under the automatic guidance of the navigation or the lane-changing intention generated under the driving of the user. The preset condition can be understood as a corresponding labeling panel is preset. A preset lane that meets the preset condition can be understood as a lane that is preset with a corresponding lane marking panel, that is to say, a lane that is not provided with a corresponding lane marking panel is not a preset lane that meets the preset condition. A preset road that meets the preset condition can be understood as a road that is preset with a corresponding road marking panel, that is to say, a road that is not provided with a corresponding road marking panel is not a preset road that meets the preset condition. Different preset lanes can be preset with corresponding different lane marking panels, and different preset roads can be preset with corresponding different road marking panels, but the displayed navigation simulation display screen does not display all of them at the same time. The lane marking panel and the road marking panel, but when the current driving route of the vehicle meets certain conditions, the corresponding lane marking panel or road marking panel is used as the marking panel to prompt.

Further, after the marking panel is determined, only when the difference between the longitude, latitude and height of the vehicle and the longitude, latitude and height of the marking panel are within the preset range, the displayed navigation simulation display screen will prompt the marking panel. That is to say, when the distance between the vehicle and the labeling panel is relatively long, the labeling panel is not prompted in the navigation simulation display screen, thereby reducing driving disturbance to the user.

In one example, take the electronic eye marking panel of the bus lane as an example. In related technologies, the marking panel can only be accurate to the road, but not the lane. The panel prompts. However, this method can be judged in combination with the vehicle lane and the driving posture: if the vehicle is going straight and is not in the bus lane, the labeling panel will not be prompted; if the vehicle is going straight but has the intention to change lanes to the bus lane, then Prompt on the labeling panel; if the vehicle is driving in the bus lane, it will prompt on the labeling panel.
