Patent Application
20220212690
This application relates to the intelligent vehicle or self-driving field, and in particular, to a vehicle-mounted device information display method, an apparatus, and a vehicle.
A self-driving technology relies on cooperation of artificial intelligence, visual computing, radar, a monitoring apparatus, and a global positioning system, so that a motor vehicle can implement self-driving without an active manual operation. Because the self-driving technology does not require a human to drive a motor vehicle, can theoretically avoid human driving mistakes effectively, reduce traffic accidents, and improve road transportation efficiency, the self-driving technology attracts increasing attention.
During self-driving, a vehicle-mounted device inside a vehicle may display a self-driving interface. A lane in which the vehicle is located and other vehicles located near the vehicle may be displayed on the self-driving interface. However, as a road surface environment becomes increasingly complex, display content of an existing self-driving interface cannot satisfy requirements of a driver.
Embodiments of this application provide a vehicle-mounted device information display method, an apparatus, and a vehicle, to enrich display content of a self-driving interface.
According to a first aspect, this application provides a vehicle-mounted device information display method, including: obtaining information about lane lines of a road surface on which a first vehicle is located, where the lane lines are at least two lines on the road surface that are used to divide different lanes; and displaying, based on the information about the lane lines, virtual lane lines whose types are consistent with those of the lane lines.
In an embodiment of this application, the virtual lane lines consistent with the lane lines corresponding to the obtained information about the lane lines are displayed on a self-driving interface, so that a driver can see, from the self-driving interface, the virtual lane lines corresponding to the types of the actual lane lines of the traveling road surface in this case. This not only enriches display content of the self-driving interface, but also improves driving safety.
It should be noted that “consistent” herein does not emphasize that the virtual lane lines are exactly the same as the lane lines of the road surface, and there may always be some differences between the virtual lane lines displayed by using a computer screen and the actual lane lines. This application is intended to indicate an actual lane to the driver for reference. The lane lines indicated in an indication manner are close to the actual lane lines as much as possible. However, presented effects of the lines may be different from those of the actual lane lines in terms of a color, a shape, a material, and the like. Further, other indication information may be displayed in addition to the virtual lane lines.
In an embodiment, the obtaining information about lane lines of a road surface on which a first vehicle is located includes: obtaining information about lane lines of a lane in which the first vehicle is located.
In an embodiment, the lane lines include at least one of the following lane lines: a dashed line, a solid line, a double dashed line, a double solid line, and a dashed solid line. It should be noted that types of the virtual lane lines displayed on the self-driving interface may be consistent with those of the actual lane lines, for example, shapes thereof are consistent.
In an embodiment, the lane lines include at least one of the following lane lines: a dashed white line, a solid white line, a dashed yellow line, a solid yellow line, a double dashed white line, a double solid yellow line, a dashed solid yellow line, and a double solid white line. It should be noted that shapes and colors of the virtual lane lines displayed on the self-driving interface may be consistent with those of the actual lane lines.

41: Obtain information about lane lines of a road surface on which a first vehicle is located, where the lane lines are at least two lines on the road surface that are used to divide different lanes.
In an embodiment of this application, the lane line may be a traveling vehicle line, a vehicle line next to the traveling vehicle line, or a traveling vehicle line of a crossing vehicle. The lane lines may include left and right lines (lines) that form a lane (lane). In other words, the lane lines are at least two lines on the road surface that are used to divide different lanes.
In an embodiment, the first vehicle may obtain an external image or video of the vehicle by using a camera or another photographing device carried by the first vehicle, and send the obtained external image or video to a processor. The processor may obtain, according to a recognition algorithm, the information about the lane lines included in the external image or video.
In an embodiment, after obtaining an external image or video of the vehicle by using a camera or another photographing device carried by the first vehicle, the first vehicle may upload the image or video to a vehicle management server. The vehicle management server processes the image, and delivers a recognition result (the information about the lane lines) to the first vehicle.
In an embodiment, the first vehicle may detect an ambient environment of a vehicle body by using a sensor (for example, a radar or a laser radar) carried by the first vehicle, and obtain the information about the lane lines outside the vehicle.
In an embodiment, the first vehicle may obtain, from a high-precision map server, the information about the lane lines of the road surface on which the first vehicle currently travels.
In an embodiment, the first vehicle may determine lane line-related information based on other data (for example, based on a current traveling speed or historical traveling data).
In this embodiment of this application, the information about the lane lines may be image information of the lane lines.
42: Display, based on the information about the lane lines, virtual lane lines whose types are consistent with those of the lane lines.
In an embodiment of this application, during self-driving of the vehicle, the display 109 may display a self-driving interface. Specifically, after the information about the lane lines of the road surface on which the first vehicle is located is obtained, the virtual lane lines whose types are consistent with those of the lane lines may be displayed on the self-driving interface.
In an embodiment, only the virtual lane lines corresponding to the lane lines of the lane in which the first vehicle 401 is located (for example, the virtual lane lines 402 shown in
In this embodiment of this application, types of the virtual lane lines displayed on the self-driving interface may be consistent with those of the actual lane lines, and specifically, shapes thereof may be consistent. Specifically, the lane lines include at least one of the following lane lines: a dashed line, a solid line, a double dashed line, a double solid line, and a dashed solid line.
In an embodiment, types of the virtual lane lines displayed on the self-driving interface may be consistent with those of the actual lane lines, and specifically, shapes and colors thereof may be consistent. Specifically, the lane lines include at least one of the following lane lines: a dashed white line, a solid white line, a dashed yellow line, a solid yellow line, a double dashed white line, a double solid yellow line, a dashed solid yellow line, and a double solid white line.
For example, a double solid yellow line is drawn on a center of a road to separate a traffic flow traveling in opposite directions.
A solid yellow line is drawn on a center of a road to separate a traffic flow traveling in opposite directions, or serves as a marking line for a bus or school bus special stop and is drawn on a roadside to indicate prohibition of parking on the roadside.
A solid white line is drawn on a center of a road to separate motor vehicles and non-motor vehicles traveling in a same direction or indicate an edge of a lane, and is drawn on an intersection to serve as a guide lane line or a stopline or guide a vehicle traveling track.
A dashed solid yellow line is drawn on a center of a road to separate a traffic flow traveling in opposite directions. A solid line side prohibits vehicles from crossing the line, and a dashed line side allows vehicles to cross the line temporarily.
In addition, the lane lines may further include a diversion line, a grid line, and the like. The diversion line may be one or more types of lines, that is, a V-shaped white line or a diagonal line area, disposed based on an intersection terrain, is used for excessively wide or irregular crossroads or crossroads with relatively complicated traveling conditions and interchange ramps or other special places, and indicates that vehicles need to travel along a stipulated route without traveling on the line or across the line. The yellow grid line indicates an area in which parking is prohibited, and indicates exclusive parking spaces when used as a marking line for parking spaces. This means that vehicles are allowed to pass through the line normally, but are not allowed to stay on the line.
It should be understood that the self-driving interface may further include other display elements, for example, a current traveling speed of the first vehicle, a speed limit of a current road surface, and other vehicles. This is not limited in this application.
It should be noted that “consistent” in this embodiment does not emphasize that the virtual lane lines are exactly the same as the lane lines of the road surface, and there may always be some differences between the virtual lane lines displayed by using a computer screen and the actual lane lines. This application is intended to indicate an actual lane to a driver for reference. The lane lines indicated in an indication manner are close to the actual lane lines as much as possible. However, presented effects of the lines may be different from those of the actual lane lines in terms of a color, a shape, a material, and the like. Further, other indication information may be displayed in addition to the virtual lane lines.
In an embodiment of this application, the virtual lane lines consistent with the lane lines corresponding to the obtained information about the lane lines are displayed on the self-driving interface, so that the driver can see, from the self-driving interface, the virtual lane lines corresponding to the types of the actual lane lines of the traveling road surface in this case. This not only enriches display content of the self-driving interface, but also improves driving safety.
In an embodiment, the first vehicle may further obtain information about a non-motor vehicle object on the road surface; and display, based on the information about the non-motor vehicle object, an identifier corresponding to the non-motor vehicle object.
In an embodiment of this application, the non-motor vehicle object includes at least a road depression, an obstacle, and a road water accumulation, and may further include a pedestrian, a two-wheeled vehicle, a traffic signal, a street lamp, various plants such as a tree, a building, a utility pole, a signal lamp, a bridge, a mountain, a hill, and the like. This is not limited herein.
In an embodiment, the first vehicle may obtain the external image or video of the vehicle by using the camera or the another photographing device carried by the first vehicle, and send the obtained external image or video to the processor. The processor may obtain, according to the recognition algorithm, the information about the non-motor vehicle object included in the external image or video.
In an embodiment, after obtaining the external image or video of the vehicle by using the camera or the another photographing device carried by the first vehicle, the first vehicle may upload the image or video to the vehicle management server. The vehicle management server processes the image, and delivers a recognition result (the information about the non-motor vehicle object) to the first vehicle.
In an embodiment, the first vehicle may detect the ambient environment of the vehicle body by using the sensor (for example, a radar or a laser radar) carried by the first vehicle, and obtain the information about the non-motor vehicle object outside the vehicle.
In an embodiment of this application, after the information about the non-motor vehicle object on the road surface is obtained, the identifier corresponding to the non-motor vehicle object may be displayed on an autonomous navigation interface. Specifically, the information about the non-motor vehicle object may include a location, a shape, a size, and the like of the non-motor vehicle object. Correspondingly, the identifier corresponding to the non-motor vehicle object may be displayed at a corresponding location of the non-motor vehicle object based on the shape and the size of the non-motor vehicle object.
It should be noted that the identifier corresponding to the non-motor vehicle object may be consistent with the non-motor vehicle object, or may be used as an example and is merely used to indicate the shape and the size of the non-motor vehicle object.
In an embodiment, a lane change indication may further be displayed when the non-motor vehicle object is located on a navigation path indicated by a navigation indication, where the navigation indication is used to indicate the navigation path of the first vehicle, and the lane change indication is used to instruct the first vehicle to avoid a traveling path of the non-motor vehicle object.
In an embodiment, when the first vehicle is in a navigation state, the first vehicle may display the navigation indication based on navigation information, where the navigation indication is used to indicate the navigation path of the first vehicle. In this case, when recognizing that the non-motor vehicle object is located on the navigation path indicated by the navigation indication, the first vehicle displays the lane change indication used to instruct the first vehicle to avoid the traveling path of the non-motor vehicle object.
It should be noted that, in an embodiment of this application, the first vehicle may obtain the external image or video of the vehicle by using the camera or the another photographing device carried by the first vehicle, and send the obtained external image or video to the processor. The processor may obtain, according to the recognition algorithm, the information about the non-motor vehicle object included in the external image or video. In this case, the information about the non-motor vehicle object may include the size, the shape, and the location of the non-motor vehicle object. The processor may determine, based on the obtained size, shape, and location of the non-motor vehicle object, whether the non-motor vehicle object is on the current navigation path.
In an embodiment, after obtaining the external image or video of the vehicle by using the camera or the another photographing device carried by the first vehicle, the first vehicle may upload the image or video to the vehicle management server. The vehicle management server processes the image, and delivers a recognition result (whether the non-motor vehicle object is on the current navigation path or whether the non-motor vehicle object obstructs vehicle traveling) to the first vehicle.
It should be noted that, the lane change indication 503 may be a strip-shaped path instruction, or may be a linear path instruction. This is not limited herein.
In an embodiment of this application, the first vehicle may directly pass through a road depression and a road water accumulation, which is different from an obstacle. If there is an obstacle, the first vehicle needs to circumvent the obstacle. When the navigation indication is displayed, if there is an obstacle on the navigation path indicated by the navigation indication, the lane change indication 503 used to instruct the first vehicle to avoid the traveling path of the non-motor vehicle object may be displayed. The lane change indication 503 may be displayed in a color and/or shape different from those/that of the current navigation indication. The navigation indication 502 may be displayed as a curved indication (as shown in
In an embodiment, a first alarm prompt may further be displayed when a distance between the first vehicle and the non-motor vehicle object is a first distance; and a second alarm prompt may further be displayed when the distance between the first vehicle and the non-motor vehicle object is a second distance, where the second alarm prompt is different from the first alarm prompt.
In an embodiment, a color or transparency of the first alarm prompt is different from that of the second alarm prompt.
Specifically, in this embodiment of this application, the first vehicle may obtain the distance between the first vehicle and the non-motor vehicle object by using a distance sensor, and display the alarm prompt based on the distance between the first vehicle and the non-motor vehicle object. The alarm prompt may change with at least two colors based on a distance to an obstacle (a collision danger level), and a smooth transition is made between two adjacent colors as the distance between the first vehicle and the obstacle increases/decreases.
In an embodiment, the first vehicle may further receive a sharing instruction, where the sharing instruction carries an address of a second vehicle; and send second shared information to the second vehicle in response to the sharing instruction, where the second shared information includes location information of the non-motor vehicle object.
In an embodiment, the first vehicle may further receive first shared information sent by a server or the second vehicle, where the first shared information includes the location information of the non-motor vehicle object; and an obstacle prompt is displayed on a navigation interface when the first vehicle enables navigation, where the obstacle prompt is used to indicate the non-motor vehicle object at a location corresponding to the location information.
It can be understood that if a road depression or a road water accumulation is relatively severe or an obstacle is relatively large, vehicle traveling may be seriously affected, and the driver may prefer to know the situation earlier rather than know it until the vehicle approaches the road depression, the road water accumulation, or the obstacle. In this case, predictions cannot be made by using only the sensor of the vehicle.
In an embodiment, after information about the road depression, the road water accumulation, or the obstacle is obtained by using a surveillance camera in a traffic system or a sensor of a vehicle that has traveled on the road surface, the information may be reported to the vehicle management server. The server delivers the information to vehicles on roads that include the road depression, the road water accumulation, or the obstacle in a navigation route, so that the vehicles can learn the information in advance.
If obtaining the information (the location, the shape, the size, and the like) about the non-motor vehicle object by using the sensor, the first vehicle may send the information about the non-motor vehicle object to another vehicle (the second vehicle). Specifically, the driver or a passenger may perform an operation on the self-driving interface (for example, triggering a sharing control on the display interface and entering the address of the second vehicle, or directly selecting the second vehicle that has established a connection to the first vehicle). Correspondingly, the first vehicle may receive the sharing instruction, where the sharing instruction carries the address of the second vehicle, and send the second shared information to the second vehicle in response to the sharing instruction, where the second shared information includes the location information of the non-motor vehicle object.
Correspondingly, an example in which the first vehicle receives shared information is used. The first vehicle receives the first shared information sent by the server or the second vehicle, where the first shared information includes the location information of the non-motor vehicle object; and the obstacle prompt is displayed on the navigation interface when the first vehicle enables navigation, where the obstacle prompt is used to indicate the non-motor vehicle object at the location corresponding to the location information.
In this embodiment of this application, the first vehicle may further display different navigation indications based on traveling speeds.
In an embodiment, the first vehicle may further obtain the navigation information of the first vehicle, and display the navigation indication based on the navigation information, where the navigation indication is used to indicate the navigation path of the first vehicle.
In an embodiment of this application, the navigation indication includes a first navigation indication or a second navigation indication. The first navigation indication is displayed based on a stationary state of the first vehicle; and the second navigation indication is displayed based on a traveling state of the first vehicle, where the first navigation indication is different from the second navigation indication.
Specifically, a display color or display transparency of the first navigation indication is different from that of the second navigation indication.
In an embodiment of this application, different navigation indications are displayed based on traveling statuses of the first vehicle, so that the driver or a passenger can determine a current traveling status of the vehicle based on display of the navigation indication on the navigation interface.
In an embodiment of this application, the first vehicle may further enable visual elements (e.g., virtual lane lines, road surfaces of lanes, navigation indications, and the like) on the autonomous navigation interface to change in at least one of a color, brightness, and a material based on a current environment (e.g., information about weather, time, and the like) in which the first vehicle is situated.
In an embodiment, the navigation indication includes a third navigation indication or a fourth navigation indication. The first vehicle may display the third navigation indication based on a first environment of the first vehicle; and display the fourth navigation indication based on a second environment of the first vehicle, where the first environment is different from the second environment, and the third navigation indication is different from the fourth navigation indication.
In another embodiment, the first vehicle may display a first lane based on the first environment of the first vehicle, and display a second lane based on the second environment of the first vehicle. The first lane and the second lane are lanes in which the first vehicle travels, or lanes of the road surface on which the first vehicle is located. The first environment is different from the second environment, and the first lane is different from the second lane.
In an embodiment, the first vehicle may enable the visual elements (the virtual lane lines, the road surfaces of the lanes, the navigation indications, and the like) on the autonomous navigation interface to change in the at least one of a color, brightness, and a material based on the current environment (the information about weather, time, and the like) in which the first vehicle is situated.
In an embodiment, the first environment includes at least one of the following environments: a weather environment in which the first vehicle is situated, a road surface environment in which the first vehicle is situated, a weather environment of a navigation destination of the first vehicle, a road surface environment of the navigation destination of the first vehicle, a traffic congestion environment of a road on which the first vehicle is located, a traffic congestion environment of the navigation destination of the first vehicle, or a brightness environment in which the first vehicle is situated.
The weather environment may be obtained by connecting a network to a weather server. The weather environment may include a temperature, humidity, a strong wind, a rainstorm, a snowstorm, and the like. The brightness environment may be brightness of the current environment in which the vehicle is situated, and may indicate current time. For example, if the current time is a morning, colors of the virtual lane lines, the road surfaces of the lanes, the navigation indications, and the like are increased compared with normal brightness or become lighter than normal brightness. If the current time is an evening, colors of the virtual lane lines, the road surfaces of the lanes, the navigation indications, and the like are decreased compared with normal brightness or become deeper than normal brightness.
For example, if the current time is a snowy day, materials of the virtual lane lines, the road surfaces of the lanes, the navigation indications, and the like are displayed as being covered by snow.
For example, when the current weather environment is severe weather (such as a strong wind, a rainstorm, or a snowstorm), the visual elements such as the virtual lane lines, the road surfaces of the lanes, and the navigation indications are enhanced for display. For example, colors are brighter (purity is improved), or brightness is increased, or enhanced materials are used.
In an embodiment of this application, the first vehicle may display the first lane based on the first environment of the first vehicle, and display the second lane based on the second environment of the first vehicle. The first lane and the second lane are the lanes in which the first vehicle travels, or the lanes of the road surface on which the first vehicle is located. The first environment is different from the second environment, and the first lane is different from the second lane. The driver or a passenger can obtain, based on display of the autonomous navigation interface, the current environment in which the vehicle is situated, especially at night or in other scenarios with relatively low brightness. This improves driving safety.
In an embodiment of this application, the first vehicle may display a corresponding image on the self-driving interface based on a geographical location of a navigation destination.
In an embodiment, the first vehicle may obtain a geographical location of the navigation destination of the first vehicle, and display a first image based on the geographical location, where the first image is used to indicate a type of the geographical location of the navigation destination of the first vehicle. The type of the geographical location may include at least one of the following: city, mountain area, plain, forest, or seaside.
In an embodiment of this application, the first vehicle may obtain the geographical location of the navigation destination of the first vehicle by using a GPS system, or obtain the geographical location of the navigation destination of the current vehicle by using a high-definition map, and further obtain attribute information (types) of the geographical locations. For example, the geographical location of the navigation destination of the first vehicle may belong to a city, a mountain area, a plain, a forest, a seaside, or the like. The attribute information (types) of the geographical locations may be obtained from a map system.
In an embodiment of this application, after obtaining the geographical location of the navigation destination and the type of the geographical location of the navigation destination, based on the type of the geographical location, the first vehicle may present a long-shot image (the first image) at a lane end location used to identify the visual elements of the lane, or change the materials of the visual elements of the lane.
It can be understood that a length, a width, and a location of a display area of the first image are all changeable. This embodiment provides only several possible examples. The first image may be displayed next to a speed identifier, may be displayed by overlapping the speed identifier, may fully occupy an upper part of an entire display panel, or the like.
The foregoing first images are merely examples, and do not constitute any limitation on this application.
In an embodiment, the first vehicle may further detect a third vehicle; obtain a geographical location of a navigation destination of the third vehicle; and display a second image based on the geographical location of the navigation destination of the third vehicle, where the second image is used to indicate a type of the geographical location of the navigation destination of the third vehicle.
In an embodiment of this application, if a driver of another vehicle (the third vehicle) is willing to disclose information about a destination (type) of the another vehicle, the type of a geographical location of the destination of the another vehicle may further be displayed on the self-driving interface.
In an embodiment of this application, the first vehicle may obtain the geographical location of the navigation destination of the first vehicle, and display the first image based on the geographical location, where the first image is used to indicate the type of the geographical location of the navigation destination of the first vehicle. The first vehicle may display a corresponding image on the self-driving interface based on a geographical location of a navigation destination, to enrich content of the self-driving interface.
In an embodiment of this application, the first vehicle may display an intersection stop indication on the self-driving interface when traveling to an intersection stop area.
In an embodiment, the first vehicle may detect that the first vehicle travels to the intersection stop area and display the intersection stop indication 901. In an embodiment, the intersection stop area may be an area to which the first vehicle travels within a preset distance (for example, 20 m) from a red light intersection.
In an embodiment, the first vehicle may determine, based on an image or a video, that the first vehicle currently enters the intersection stop area, or may determine, based on the navigation information, that the first vehicle currently enters the intersection stop area.
In an embodiment, the first vehicle may obtain a status of a traffic light that is corresponding to the first vehicle and that is at a current intersection, and display a first intersection stop indication when the status of the traffic light is a red light or yellow light state.
It should be noted that, if the first vehicle is in a navigation state, a navigation indication 701 may further be displayed, and a part that is of the navigation indication 701 and that is beyond the intersection stopline is weakened for display. A weakening manner may be displaying only an outline of the navigation indication 701, increasing transparency of the navigation indication 701, or the like. This is not limited herein.
In an embodiment, the intersection stop indication includes the first intersection stop indication or a second intersection stop indication. The first vehicle may display the first intersection stop indication when detecting that a vehicle head of the first vehicle does not exceed the intersection stop area; and display the second intersection stop indication when detecting that the vehicle head of the first vehicle exceeds the intersection stop area, where the first intersection stop indication is different from the second intersection stop indication.
In an embodiment of this application, when the vehicle head of the first vehicle exceeds the intersection stop indication 901, display content of the first intersection stop indication 901 may be changed. For example, the intersection stop indication may be weakened for display. A weakening manner may be increasing transparency of the intersection stop indication or the like. This is not limited herein.
In another embodiment, the intersection stop indication includes a third intersection stop indication or a fourth intersection stop indication. The first vehicle may display the third intersection stop indication when detecting that the first vehicle travels to the intersection stop area and that a traffic light corresponding to the intersection stop area is a red light or a yellow light; and display the fourth intersection stop indication when detecting that the first vehicle travels to the intersection stop area and that a traffic light corresponding to the intersection stop area is a green light, where the third intersection stop indication is different from the fourth intersection stop indication.
In an embodiment of this application, the first vehicle displays the intersection stop indication when traveling to the intersection stop area, and information about the traffic light at the current intersection is further considered. Specifically, the first vehicle displays the third intersection stop indication when the first vehicle travels to the intersection stop area and the traffic light corresponding to the intersection stop area is a red light or a yellow light; and displays the fourth intersection stop indication when the first vehicle travels to the intersection stop area and the traffic light corresponding to the intersection stop area is a green light. For example, the fourth intersection indication may be an enhanced third intersection indication (that is, changing a color or reducing transparency of the navigation indication 701).
In an embodiment of this application, the first vehicle may display a vehicle alarm prompt on the self-driving interface based on a distance between a nearby vehicle and the current vehicle.
In an embodiment, the first vehicle may detect a fourth vehicle; and display a vehicle alarm prompt when a distance between the fourth vehicle and the first vehicle is less than a preset distance.
In an embodiment, the vehicle alarm prompt includes a first vehicle alarm prompt or a second vehicle alarm prompt. The first vehicle may display the first vehicle alarm prompt when the distance between the fourth vehicle and the first vehicle is the first distance; and display the second vehicle alarm prompt when the distance between the fourth vehicle and the first vehicle is the second distance, where the first distance is different from the second distance, and the first vehicle alarm prompt is different from the second vehicle alarm prompt.
In an embodiment of this application, the first vehicle may obtain distances between other vehicles and the first vehicle by using the distance sensor carried by the first vehicle, and display the vehicle alarm prompt after detecting that the distance between a vehicle (the fourth vehicle) and the first vehicle is less than the preset distance.
In an embodiment of this application, when another vehicle (the fourth vehicle) is around the first vehicle, an alarm alarm prompt (a danger prompt graphic) may be displayed on the self-driving interface by using a nearest point at which the current vehicle approaches the fourth vehicle as a center of a circle.
In an embodiment, colors of the alarm prompts may be different based on the distance between the fourth vehicle and the first vehicle. For example, the alarm prompt is displayed in red when the distance is particularly short, and is displayed in yellow when the distance is relatively short.
In an embodiment, when the distance between the fourth vehicle and the first vehicle continuously changes, the color of the danger prompt graphic may be changed gradually, instead of suddenly changing from red to yellow (or from yellow to red) when the corresponding threshold is exceeded.
In an embodiment of this application, the first vehicle may display a vehicle alarm prompt on the self-driving interface based on a distance between a nearby vehicle and the current vehicle, so that the driver can know a collision risk between the first vehicle and the another vehicle by using the alarm prompt displayed on the self-driving interface.
In an embodiment of this application, when the first vehicle changes from a turning state to a straight-driving state, or when the first vehicle changes from a straight-driving state to a turning state, the first vehicle may change a current display field of view of the self-driving interface.
Specifically,
In this embodiment of this application, before turning right, the driver pays more attention to right-front information, to mainly determine whether there is a pedestrian. Therefore, the right-front scene area 1102 that is included in the second area and that is in the traveling direction of the first vehicle is greater than the right-front scene area 1101 included in the first area.
In an embodiment of this application, after turning left, the driver pays more attention to right-rear information, to mainly determine whether there is an incoming vehicle. Therefore, the right-rear scene area 1103 that is included in the third area and that is in the traveling direction of the first vehicle is greater than the right-rear scene area 1104 included in the fourth area.
In an embodiment of this application, before turning left, the driver pays more attention to left-front information, to mainly determine whether there is a pedestrian. Therefore, the left-front scene area 1105 that is included in the fifth area and that is in the traveling direction of the first vehicle is greater than the left-front scene area 1106 included in the sixth area.
In an embodiment of this application, after turning left, the driver pays more attention to right-rear information, to mainly determine whether there is an incoming vehicle. Therefore, the right-rear scene area 1107 that is included in the seventh area and that is in the traveling direction of the first vehicle is greater than the right-rear scene area 1108 included in the eighth area.
It should be noted that the scene areas obtained through division in
In other words, in this embodiment of this application, the first vehicle may change, based on an intersection turning area, a display field of view at which information is displayed on the display. Specifically, the turning area may be obtained by sensing whether a steering wheel rotates left or right. Alternatively, whether high-precision map navigation is enabled during vehicle traveling is determined and then whether the vehicle has traveled to an intersection requiring a left turn or a right turn is determined by using a navigation route. Alternatively, during vehicle traveling, only a high-precision map is enabled but no navigation is used, and the driver drives the vehicle instead; in this case, whether the vehicle needs to turn left or turn right is further determined by determining whether the vehicle travels at a preset distance close to an intersection and travels in a left-turn lane or a right-turn lane.
The field of view in this embodiment is a field of view at which information is displayed on the display. Specifically, a location of the current vehicle (e.g., the first vehicle) may be tracked by using a virtual camera, to present an object that can be seen in the field of view of the camera. Changing the display field of view means changing a location of the virtual camera relative to the current vehicle (x-axis, y-axis, and z-axis coordinates and angles in various directions), to present, on the display, a change of the object that can be seen in the field of view of the virtual camera.
For example, the current vehicle is used as an origin of coordinates, a direction facing a front side of the vehicle is a positive direction of a y-axis, and the traveling direction of the vehicle is a negative direction of the y-axis; and facing the vehicle, a right-hand side of the vehicle is a positive direction of an x-axis, and a left-hand side of the vehicle is a negative direction of the x-axis. The location of the virtual camera is above a z-axis, and is in a positive direction of the z-axis and in the positive direction of the y-axis. A field of view in this default state is referred to as a default field of view (referred to as a “default forward field of view” in the following embodiment).
It can be understood that a location of the origin and directions of various axes can be customized by a developer.
Turning right is used as an example. Before turning right, the driver pays more attention to right-front information, to mainly determine whether there is a pedestrian; and after the turning, the driver pays more attention to left-rear information, to mainly determine whether there is an incoming vehicle. If it is determined that the driver is about to turn right, the field of view of the virtual camera is changed from the default forward field of view to look right first (e.g., the virtual camera rotates right, and rotates from a direction facing the negative direction of the y-axis to the negative direction of the x-axis), and then the field of view of the virtual camera is changed to look left (e.g., the virtual camera rotates left, and rotates to the positive direction of the x-axis). After the turning ends and straight driving starts, the default forward field of view is restored (as shown in
In an embodiment of this application, when the first vehicle changes from a turning state to a straight-driving state, or when the first vehicle changes from a straight-driving state to a turning state, the first vehicle may change a current display field of view, so that the driver can know information about an area that may have a safety risk when the vehicle turns. This improves driving safety.
In this embodiment of this application, the first vehicle may change the current display field of view of the self-driving interface based on a change of a traveling speed.
In an embodiment, the first vehicle may display a ninth area based on a first traveling speed of the first vehicle, and display a tenth area based on a second traveling speed of the first vehicle, where the ninth area and the tenth area are scene areas in which a traveling location of the first vehicle is located, the second traveling speed is higher than the first traveling speed, and a scene area included in the ninth area is greater than a scene area included in the tenth area.
In an embodiment of this application, the first vehicle may make a road field of view displayed on the self-driving interface larger when the traveling speed of the vehicle increases, and correspondingly a road display range is larger. As the traveling speed of the vehicle decreases, more road information (buildings on both sides of a lane, pedestrians, roadside traffic facilities, and the like) displayed on a display panel becomes more obvious, and a road field of view displayed on the display panel becomes smaller, leading to a smaller road display range (the scene area in which the traveling location of the first vehicle is located).
For details about how to obtain through transformation the road field of view displayed on the self-driving interface, refer to the descriptions in the foregoing embodiment. Details are not described herein again.
As shown in
In addition, when the vehicle speed is relatively low, for example, when the vehicle travels in a street, the driver pays more attention to information about the surroundings of the vehicle, such as details of collision information. In this case, the field of view is closer to the vehicle, so that the driver focuses on information as the driver wants. As more road information (e.g., buildings on both sides of a lane, pedestrians, roadside traffic facilities, and the like) displayed on the display panel becomes more obvious, the road field of view displayed on the self-driving interface becomes smaller, leading to a smaller road display range. As shown in
In an embodiment of this application, the first vehicle may display the ninth area based on the first traveling speed of the first vehicle, and display the tenth area based on the second traveling speed of the first vehicle, where the ninth area and the tenth area are the scene areas in which the traveling location of the first vehicle is located, the second traveling speed is higher than the first traveling speed, and the scene area included in the ninth area is greater than the scene area included in the tenth area. In the foregoing manner, when the traveling speed of the first vehicle is relatively high, a larger scene area may be displayed, so that the driver can know more road surface information when the traveling speed is relatively high. This improves driving safety.
In an embodiment of this application, the first vehicle may display, on the self-driving interface, a prompt indicating that a vehicle beside the first vehicle is inserted into the current traveling lane.
In an embodiment, the first vehicle may detect a fifth vehicle; display, when the fifth vehicle is located on a lane line of a lane in front of the traveling direction of the first vehicle, a third image corresponding to the fifth vehicle; and display, when the fifth vehicle travels to the lane in front of the traveling direction of the first vehicle, a fourth image corresponding to the fifth vehicle, where the third image is different from the fourth image.
In an embodiment of this application, when detecting that a vehicle (the fifth vehicle) is located on the lane line of the lane in front of the traveling direction of the first vehicle, the first vehicle determines that the fifth vehicle will overtake the first vehicle.
In an embodiment, the first vehicle may further determine, when the fifth vehicle is located on the lane line of the lane in front of the traveling direction of the first vehicle and a distance between the fifth vehicle and the first vehicle is less than a preset value, that the fifth vehicle will overtake the first vehicle.
In an embodiment, the first vehicle may process a photographed image or video, to determine that the fifth vehicle is located on the lane line of the lane in front of the traveling direction of the first vehicle. The first vehicle may send the photographed image or video to the server, so that the server determines that the fifth vehicle is located on the lane line of the lane in front of the traveling direction of the first vehicle, and then the first vehicle receives a determining result sent by the server.
In an embodiment of this application, for example, the fifth vehicle may be located behind the first vehicle (as shown in
In an embodiment of this application, after detecting that the fifth vehicle completes overtaking, the first vehicle may change display content of the fifth vehicle. Specifically, the first vehicle may display, when the fifth vehicle travels to the lane in front of the traveling direction of the first vehicle (for a fifth vehicle 1301 shown in
