fig. 1 shows an application scenario of a method for displaying dynamic traffic situation in an on-board display according to an embodiment of the present invention.
Detailed Description
Embodiments of the present invention are described below with reference to the drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of, and enabling description for, those skilled in the art. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some of these specific details. Furthermore, it should be understood that the invention is not limited to the specific embodiments described. Rather, any combination of the features and elements described below is contemplated as carrying out the invention, whether or not they relate to different embodiments. Thus, the following aspects, features, embodiments and advantages are merely illustrative and are not considered elements or limitations of the claims except where explicitly recited in a claim.
In the invention, the vehicle can obtain static traffic background information (such as road information and static facility information around the road, which is derived from a high-precision map, the road information can include various road routes, the static facility can include road-side traffic signs, buildings and other facilities) and motion state information (such as broadcast information derived from various traffic participants and/or a road-side intelligent system) of traffic participants (such as vehicles, pedestrians, bicycles and the like near the vehicle) around the vehicle (such as the distance between the vehicle and the vehicle is less than a set threshold value, such as 200 meters) by communicating with the V2X of the device outside the vehicle, namely the position, speed and motion direction information of the various traffic participants, and the motion state information of the vehicle, so as to construct a complete local road condition model in the electronic system inside the vehicle. The road condition model includes information on the motion state of vehicles or pedestrians in a blind area (e.g., sheltered from other vehicles, buildings, or trees) that is not temporarily visible around the host vehicle. The dynamic traffic situation around the vehicle is displayed in a regional global overlooking mode, specifically, a forward overlooking visual angle from the right above the vehicle (namely, an observation point is several meters above the vehicle) or the back above the vehicle (namely, the observation point is several meters behind the vehicle) is constructed according to a local road condition model, and traffic participants moving around the vehicle are superposed on a static traffic background by using a virtual reality 3D technology, so that the dynamic traffic situation around the vehicle is displayed on a vehicle-mounted display in a dynamic 3D virtual reality scene, and a driver can conveniently establish an intuitive corresponding relationship between a target displayed in a picture and traffic participants in the real world. The virtual reality 3D display effect visual computing resource capacity of the road and traffic participants is correspondingly adapted so as to achieve the dynamic, smooth and real display effect as far as possible. The computing resources required to construct the virtual reality 3D display may be from the vehicle-mounted computer of the vehicle, or from a cloud device communicatively connected to the vehicle via a mobile communication network (e.g., a 5G network), or a mixture of the two. Any suitable on-board display may be used for display, such as a center console, dashboard, or heads-up display.
In the invention, local traffic situation (dynamic position of each traffic participant) is presented to the driver on the vehicle-mounted display by virtual reality 3D technology, so that the driver can easily combine the acquired information with the actual scene of the driving vehicle, thereby assisting the subsequent driving behavior. The invention visually presents the complex traffic environment situation in a visual and clear virtual reality mode, thereby playing a role in assisting driving.
In the virtual reality display, the ground road and the marking lines such as the related solid lines, the dotted lines and the pedestrian crossing, the road side signs, the roadside buildings, the green belts and other static objects on the ground road have clear and recognizable characteristics, and have consistency and matching degree with the actual environment condition of the vehicle, so that the driver can conveniently establish visual corresponding relation between the display content and the objects and positions in the front and the side of the vehicle in the real world.
In the virtual reality display, the display screen is constantly in dynamic change according to the position of the host vehicle, and the states of the static object and the dynamic target changing along with the change of the position of the host vehicle are constantly reflected, including the switching of the object (for example, after the vehicle passes by the object forwards, the object gradually disappears from the screen) and the motion (for example, the vehicle moves along with the motion track of the actual vehicle in the screen).
In the invention, the vehicle-mounted computer and/or the cloud equipment can calculate the collision risk between the traffic participants around the vehicle and the vehicle according to the motion state information of the traffic participants around the vehicle. Accordingly, the traffic participants who are at risk of collision with the host vehicle are displayed in a highlighted warning. When the potential collision risk comes from a traffic participant outside the screen (e.g., a vehicle behind a right adjacent lane when changing lanes to the right), the approximate direction of the collision risk (e.g., rear, left rear, right rear, etc.) may be embodied in the display screen of the in-vehicle display by a highlight warning.
The collision risk includes potential collisions between the vehicle and the host vehicle, potential collisions occurring on the host vehicle caused by other vehicles, and potential collisions between the host vehicle and non-motor vehicles and pedestrians. For example, if a vehicle stops, slows down or decelerates in the same lane immediately ahead, even if another vehicle in close proximity is present between the stopped vehicle and the host vehicle, the vehicle may be caused to collide with the host vehicle by taking measures such as braking and lane changing. Therefore, the stopped, slow or decelerated vehicle is also highlighted as a collision risk.
"highlight warning" means that a prompt is made in a special color, brightness, and/or blinking state in a display screen, or a warning is made in a special sound.
In the present invention, the highlighted warnings may be ranked according to the estimated time of collision with the host vehicle, with different levels of highlighted warning corresponding to different colors, brightness, blinking states, and/or sounds. For example, the highlighted warning may be classified as a low risk warning, a medium risk warning, and a high risk warning. For example, the low risk warning may be an object that may collide with the host vehicle five to ten seconds later prompted in a yellow flash font. The medium risk warning may be in a red slow flashing font for alerting objects between two and five seconds that may collide with the host vehicle. The high risk warning may be an object that may collide with the host vehicle in red flash font and voice prompt within two seconds.
In the invention, the vehicle-mounted display carries out highlight warning on the traffic participants with collision risks with the vehicle, so that the driver can conveniently and intuitively know the potential collision risks, and the driver is warned to take necessary driving behaviors to avoid the potential risks.
In addition, in the invention, the broadcast information from traffic participants around the vehicle, a road side intelligent system and/or a vehicle networking operation service center can be acquired through the communication between the vehicle-mounted system and the V2X of the device outside the vehicle. When there is traffic assistance information in the broadcast information, such as a forbidden area, a traffic accident, a traffic jam, an abnormal road condition (e.g., a road spill), an abnormal state vehicle (e.g., an anchor vehicle), and/or a special vehicle (e.g., a fire truck), a dynamic prompt may be presented in the display screen. For example, the traffic assistance information may be prompted in a yellow slow flashing font.
In the invention, the roadside intelligent system can comprise a sensing device and a server. Roadside intelligence systems may be placed on static facilities around the road. For example, at an intersection, the sensing devices and server may be located on the legs of a traffic light, or the server may be buried beneath the ground surface. The sensing devices may be one or more of a camera, a millimeter wave radar, a laser radar, and the like, so that the position, the movement speed, and the movement direction of each traffic participant can be detected. Each sensor collects the motion state information of the traffic participants in the sensing range in real time and then transmits the motion state information of the traffic participants to the server. The server generates movement state information of the traffic participants of the local area based on the movement state information received from each sensor. The roadside intelligent system may be connected to each vehicle in the local area through one-way communication or two-way communication. For example, the roadside intelligence system may provide the state of motion information of the various traffic participants of the local area to vehicles in the local area in a broadcast manner. Each vehicle entering the local area may receive the broadcast from the roadside intelligence system and identify surrounding objects, and may calculate the likelihood of a collision from the state of motion information of the surrounding objects.
Fig. 1 illustrates an application scenario of a method for displaying a dynamic traffic situation in an on-vehicle display according to an embodiment of the present invention, according to the principle of the method for displaying a dynamic traffic situation in an on-vehicle display disclosed in the present invention.
In fig. 1, a roadside intelligent system 1 is provided on a bracket of a traffic light. The roadside intelligent system 1 generates the movement state information of all the traffic participants at the intersection and provides the movement state information of the respective traffic participants to the vehicles passing through the intersection in a broadcast manner. After the vehicle 2 runs to the intersection and receives the broadcast of the roadside intelligent system 1, the collision risk between the vehicle 2 and each traffic participant is calculated according to the motion state information of each traffic participant. By calculation, the host vehicle 2 knows that there is a risk of collision with the pedestrian 4 crossing the road ahead of the stationary vehicle 3 after 4 seconds, a risk of collision with the oncoming vehicle 5 after 8 seconds, and a risk of collision with the oncoming vehicle 8 (the vehicle 8 is outside the display screen) after 9 seconds. Further, the host vehicle 2 is informed from the broadcast that there are an anchor vehicle 6 and a fire engine 7 at the intersection. At this time, in addition to displaying the dynamic positions of the traffic participants at the intersection by the virtual reality 3D technique, the display screen of the vehicle-mounted display highlights the pedestrian 4 in a red flash font and a voice, highlights the rear of the vehicle 5 and the host vehicle 2 in a red slow flash font, and dynamically presents the breakdown vehicle 6 and the fire engine 7 in a yellow slow flash font, so that the driver can quickly and intuitively identify the potential risk to warn the driver that the driver needs to avoid the potential risk by adopting necessary driving behaviors. After the collision risk is released, the highlighted warning for the corresponding object may be released. For example, after the pedestrian 4 stops traveling and keeps a safe distance from the host vehicle, the highlighted warning to the pedestrian 4 is stopped.
It should be noted that the above description is only an example and not a limitation of the present invention. In other embodiments of the invention, the method may have more, fewer, or different steps, and the order, inclusion, or functional relationship between the steps may be different from that described and illustrated. For example, in general, multiple steps may be combined into a single step, or a single step may be split into multiple steps. For a person skilled in the art, the sequence of the steps is not changed without creative efforts and is within the protection scope of the invention.
