Detailed Description
Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
With the heat of the automatic driving technology, the automatic driving technology is not only limited to be applied to cars, but also widely applied to buses. The automatic driving bus is a common tool for public travel, and the basic capability of the bus is to provide a safer travel mode.
Autonomous vehicles, particularly autonomous buses, operate in a collective environment including other vehicles, pedestrians, and traffic lights while traveling on the road. Therefore, the autonomous vehicle needs to keep necessary contact with the external environment and transmit information to the outside to inform the external environment of the self condition of the autonomous vehicle, road condition information, and the like. The interaction between the automatic driving vehicle and other vehicles is realized, and the transmission of the bearing vehicle road information is the core appeal of an external vehicle screen.
Compared with the core module of automatic driving, the external screen of the vehicle enriches the external interaction capability of the automatic driving vehicle although the technical barrier is lower. The external screen of the vehicle is used as an information transmission medium, technically supports various mainstream multimedia formats, and can vividly and vividly transmit information to the outside in various scenes; in content production, the emotion is conveyed to the outside by displaying the anthropomorphic expressions, and the multimedia resource display scheme of the external screen of the vehicle is continuously optimized, so that the automatic driving vehicle is closer to the public.
However, in the related art, in the scheme of displaying the multimedia resources through the external screen of the vehicle, the remote control platform continuously sends the multimedia signals to the external screen of the vehicle, and the external screen of the vehicle analyzes the multimedia signals to obtain the multimedia resources, so as to display the multimedia resources.
In the multimedia resource display scheme, interaction between the vehicle and the external environment belongs to static interaction, and when the external screen receives multimedia signals, corresponding multimedia resources are displayed, so that the external interaction capability of the vehicle is weak, the application scene is single, and the expansibility cannot be poor.
In order to solve the above problem, an embodiment of the present disclosure provides a multimedia resource display method, as shown in fig. 1, the method may be applied to an electronic device connected to a core module of a mobile driver and connected to an exterior screen of a vehicle, and may also be applied to an upper layer application connected to the core module of the mobile driver, which is not limited herein. For ease of understanding, the following explanation will be made with an electronic apparatus as an execution subject. The multimedia resource display method comprises the following steps:
in step S11, a first state event is generated as a target event based on the running state data of the autonomous vehicle.
In the embodiment of the present disclosure, the autonomous vehicle may be an autonomous car or an autonomous bus, which is not limited to this.
The driving state data may include, but is not limited to, such things as, host vehicle information, obstacle information, routing lines, collision alert data, and end-of-vehicle net speed measurements. The host vehicle information may include, but is not limited to, speed, position, length, width, throttle status, brake status, steering wheel angle, gear, and turn signal status, among others. Obstacles may include, but are not limited to, vehicles, pedestrians, bicycles, and other objects, etc.
Status events may include, but are not limited to, default events, upcoming inbound events, outbound events, hard brake events, lane change events, and vehicle-to-ambient information interaction (V2X) events, among others.
Wherein, the default event is: and loading a state event when no state event is generated, wherein the default event can be the state event for triggering the display of multimedia resources such as brand advertisements or public service information.
The upcoming inbound event is: a status event generated when an autonomous vehicle is identified as about to approach a stop.
The event of entering the station is as follows: a status event generated when an arrival of an autonomous vehicle is identified.
The outbound event is: a status event generated when the autonomous vehicle is identified as being out of the station.
The hard braking event is: a condition event occurs when the autonomous vehicle is braked suddenly in an emergency.
The lane change event is: a status event is generated when the autonomous vehicle needs to change lanes.
The V2X event is: a state event generated when a traffic light of a lane in which an autonomous vehicle is located malfunctions or a traffic accident occurs.
The core module of the automatic driving vehicle consists of a plurality of sensors, and the sensors acquire the driving state data of the automatic driving vehicle in real time. In the disclosed embodiment, the electronic device generates a status event based on the driving status data of the autonomous vehicle. For ease of understanding, this state event is referred to as the first state event and is not limiting. The electronic device takes the first state event as a target event.
In an alternative embodiment, the electronic device may generate the first status event based on the driving status data of the autonomous vehicle, in combination with map, positioning data, and route information.
For example, the route information of the autonomous vehicle is: the starting station is station a at position 1, the destination station is station C at position 3, and station B at position 2 is passed through. The electronic equipment determines that the distance between the automatic driving vehicle and the station B is smaller than a first distance threshold value by combining the position 2 of the station B according to the driving state data of the automatic driving vehicle, and the distance between the automatic driving vehicle and the station B is gradually reduced, so that a first state event is generated as an event about to enter the station B; the electronic equipment determines that the distance between the automatic driving vehicle and the station B is smaller than a second distance threshold value by combining the position 2 of the station B according to the driving state data of the automatic driving vehicle, and the distance between the automatic driving vehicle and the station B is gradually reduced, so that a first state event is generated as a station B entering event; and the electronic equipment determines that the distance between the automatic driving vehicle and the station B is smaller than a third distance threshold value by combining the position 2 of the station B according to the driving state data of the automatic driving vehicle, and the distance between the automatic driving vehicle and the station B is gradually increased, so that the first state event is generated as the station B exit event.
The first distance threshold, the second distance threshold and the third distance threshold can be set according to actual requirements.
Step S12, determining a target multimedia resource associated with the target event according to the pre-stored association relationship between the state event and the multimedia resource.
In the disclosed embodiment, the multimedia resources may include, but are not limited to, video, audio, images, and the like.
The electronic equipment stores the association relationship between the state event and the multimedia resource in advance. After the target event is obtained, the electronic equipment searches the incidence relation including the target event from the incidence relation of the pre-stored state event and the multimedia resource, and takes the multimedia resource included in the searched incidence relation as the target multimedia resource.
If the incidence relation of the target event is not included, the electronic equipment can take the default event as the target event, search the incidence relation including the default event from the incidence relation of the prestored state event and the multimedia resource, and take the multimedia resource included in the searched incidence relation as the target multimedia resource.
And step S13, displaying the target multimedia resource through the external screen of the automatic driving vehicle.
After the target multimedia resource is acquired, the electronic equipment can send the target multimedia resource to the external vehicle screen through the network protocol, and then the external vehicle screen renders the target multimedia resource, so that the purpose of displaying the target multimedia resource is achieved.
In the technical scheme provided by the embodiment of the disclosure, a C/S (Server/Client/Server) structure can be adopted, that is, an external screen of the vehicle is used as a Server, a module (such as the electronic device) integrating the external screen of the vehicle is used as a Client, and the Client controls the external screen of the vehicle through a network protocol. The upper-layer Client only needs to pay attention to the service, the stored state events and the multimedia resources related to the state events can be dynamically adjusted according to the service requirements, the multimedia resources displayed on the outer screen of the vehicle can be adjusted in real time according to the running state data of the automatic driving vehicle, the vehicle-exterior interaction capacity of the vehicle is strong, and the system expansibility, stability, convenience and display richness are improved.
In addition, the external screen of the automobile can be communicated with other equipment by adopting a standard network protocol, so that the external screen of the automobile can be integrated on various platforms, and the universality of the external screen of the automobile is improved.
Based on the multimedia resource display method shown in fig. 1, an embodiment of the present disclosure further provides a multimedia resource display method, as shown in fig. 2, in the method, steps S21-S23 are the same as steps S11-S13, and are not described herein again. The method may further comprise the steps of:
step S24: and generating a second state event according to the driving state data of the automatic driving vehicle in the process of displaying the target multimedia resource.
In the embodiment of the disclosure, in the process of displaying the target multimedia resource, the electronic device continuously acquires the driving state data of the autonomous vehicle. When the acquired driving state data of the autonomous vehicle meets the condition for generating the state event, as exemplified in step S11, if "the distance between the autonomous vehicle and the B station is less than the first distance threshold and the distance between the autonomous vehicle and the B station is gradually decreasing", the electronic device generates a new state event according to the driving state data of the autonomous vehicle. For ease of understanding, the new state event is referred to as a second state event and is not limiting.
In step S25, the second state event is set as a new target event, and step S22 is executed again.
In the embodiment of the disclosure, after acquiring a new second state event, the electronic device may directly use the second state event as a new target event, and determine a new target multimedia resource based on the new target event, thereby controlling the external screen of the vehicle and displaying the new target multimedia resource. Therefore, the outer screen of the vehicle displays the multimedia resources related to the latest state event in real time, and the outer interaction capacity of the vehicle is further improved.
Based on the multimedia resource display method shown in fig. 2, an embodiment of the present disclosure further provides a multimedia resource display method, as shown in fig. 3, in the method, steps S31-S34 and S36 are the same as steps S21-S25, and are not described again here. The method may further comprise the steps of:
step S35, detecting whether the priority of the second state event is greater than or equal to the priority of the first state event, and obtaining the detection result. In response to the detection result being: the priority of the second state event is greater than or equal to the priority of the first state event, and step S36 is performed. In response to the detection result being: and the priority of the second state event is less than that of the first state event, and the target multimedia resource is continuously displayed without any treatment.
In step S36, the second state event is set as a new target event, and step S32 is executed again.
In the disclosed embodiment, each state event is configured with a corresponding priority. The priority of each state event can be set according to actual requirements. For example, the importance level of a status event is configured in advance, and the higher the importance level of a status event is, the higher the priority of the status event is. For another example, the importance level of a state event is configured in advance, and the higher the importance level of a state event is and the later the generation time is, the higher the priority of the state event is.
After acquiring a new second state event, the electronic device detects whether the priority of the second state event is greater than or equal to the priority of the first state event. And if the detection result is that the priority of the second state event is greater than or equal to the priority of the first state event, the electronic equipment takes the second state event as a new target event, and then displays the target multimedia resource associated with the new target event through the external screen of the vehicle so as to improve the external interaction capacity of the vehicle.
If the detection result shows that the priority of the second state event is smaller than that of the first state event, the second state event is less important than the first state event, and the electronic equipment continues to display the originally determined target multimedia resource so as to ensure the safety of the automatic driving vehicle.
For example, the electronic device generates a state event 1 according to the driving state data of the autonomous vehicle, determines a multimedia resource 1 associated with the state event 1, and displays the multimedia resource 1 through an external screen of the autonomous vehicle; then, the electronic equipment generates a new state event 2 according to the driving state data of the automatic driving vehicle; if the priority of the state event 2 is greater than or equal to the priority of the state event 1, the electronic equipment determines the multimedia resource 2 associated with the state event 2, and then displays the multimedia resource 2 through the external screen of the vehicle; and if the priority of the state event 2 is smaller than that of the state event 1, the electronic equipment continues to display the multimedia resource 1 through the external screen of the vehicle.
In the embodiment of the disclosure, when a new state event is acquired, the electronic device can control the external screen of the vehicle to display the multimedia resource according to actual requirements, so that the flexibility of multimedia resource display is improved.
In one embodiment of the present disclosure, the state events are time-efficient, i.e., the state events have a validity period. The starting time of the validity period of the status event is: the time of generation of the state event; the expiration time of the validity period of the status event is: and the generation time of the state event and the sum of the total display time of the multimedia resources related to the state event. For example, if the generation time of the state event 1 is 8:00, and the total display time of the state event 1 is 10 minutes, the validity period of the state event 1 is 8: 00-8: 10.
Based on the validity period of the state event, the embodiment of the present disclosure further provides a multimedia resource display method, as shown in fig. 4, in the method, steps S41-S43 are the same as steps S11-S13, and are not described herein again. The method may further comprise the steps of:
in step S44, in the process of displaying the target multimedia resource, in response to the expiration date of the target event being exceeded, the display of the target multimedia resource is stopped.
In the process of determining the target multimedia resource and displaying the target multimedia resource, the electronic equipment monitors whether the current time exceeds the validity period of the target event in real time. And if the current time exceeds the validity period of the target event, the target event is invalid, and the target multimedia resource is stopped being displayed.
For example, the validity period of the state event 1 is 8: 00-8: 10, and the electronic device displays the multimedia resource 1 associated with the state event 1 through the external screen of the vehicle. When the current time exceeds the validity period of the state event 1 when the time reaches 8:10, the electronic equipment stops displaying the multimedia resource 1 even if the display duration of the multimedia resource 1 is less than 10 minutes.
When the automatic driving vehicle interacts with the external environment, each generated state event has timeliness, for example, for an arrival event, the validity period of the arrival event is only a few seconds or a few tens of seconds of the arrival of the vehicle, and when the validity period is exceeded, the vehicle is already out of the station, and the multimedia resource related to the arrival event is completely and inefficiently displayed. Therefore, according to the technical scheme provided by the embodiment of the disclosure, the external screen is controlled to display the multimedia resources based on the validity period of the state event, so that the validity and the practicability of the multimedia resource display scheme are improved.
In the embodiment of the disclosure, in the process of displaying the target multimedia resource, if any state event with priority higher than that of the target event is not generated, the electronic device may continuously display the target multimedia resource no matter whether the validity period of the target event is exceeded or not, until the duration of displaying the target multimedia resource reaches the total duration of displaying the target multimedia resource.
Based on the validity period of the state event, the embodiment of the present disclosure further provides a multimedia resource display method, as shown in fig. 5, in the method, steps S51-S53 are the same as steps S11-S13, and are not described herein again. The method may further comprise the steps of:
step S54, after the display of the target multimedia resource is finished, acquiring a third status event with the highest priority from the generated status events in the validity period as a new target event, and re-executing step S52.
In the embodiment of the disclosure, when the duration for displaying the target multimedia resource reaches the total duration for displaying the target multimedia resource, or when the current time exceeds the validity period of the target event, the displaying of the target multimedia resource is finished. After the display of the target multimedia resource is finished, the electronic equipment acquires the state event with the highest priority from the generated state events in the validity period. For ease of understanding, the state event with the highest priority is referred to as the third state event and is not limiting. And the electronic equipment takes the third state event as a new target event, and further executes the step S52 again, determines a new target multimedia resource, and displays the new target multimedia resource through the external screen of the vehicle.
In an optional embodiment, to improve the effect of acquiring the third status event with the highest priority, the electronic device may manage the status events through a queue. Specifically, the electronic device may add the generated state events to the queue, and sequence the state events in the queue according to the priority; the subsequent electronic equipment can obtain the corresponding multimedia resource by reading the state event in the queue, and then control the external screen of the vehicle to render and display by using a network protocol.
According to the technical scheme, the electronic equipment displays the multimedia resource with the highest priority in real time through the external screen of the vehicle, and the safety of the automatic driving vehicle is improved.
Based on the multimedia resource display method shown in fig. 5, the embodiment of the present disclosure further provides a multimedia resource display method, as shown in fig. 6, in the method, steps S61, S62, and S64 are the same as steps S51, S52, and S54, and are not repeated here. Step S63 in the method may be:
and step S63, displaying the target multimedia resource from the initial time when the target multimedia resource does not display the content through the external screen of the automatic driving vehicle. Step S63 is one implementation of step S53.
After the target multimedia resource is determined, the electronic equipment determines the starting time of the non-displayed content of the target multimedia resource, and displays the target multimedia resource from the starting time of the non-displayed content of the target multimedia resource through the external screen of the vehicle.
For example, the validity period of the status event 1 is 8: 00-8: 10, and the validity period of the status event 2 is 8: 01-8: 06. At 8:00, the electronic equipment displays the multimedia resource 1 associated with the state event 1; at 8:01, the electronic equipment displays the multimedia resource 2 associated with the state event 2; at 8:06, the presentation of the multimedia asset 2 is finished, and at this time, if the electronic device still presents the multimedia asset 1, since the multimedia asset 1 has been presented for 1 minute, that is, the starting time of the non-presentation of the content by the multimedia asset 1 is 1 st minute, at 8:06, the electronic device continues to present from the 1 st minute of the multimedia asset 1.
According to the technical scheme provided by the embodiment of the disclosure, when the electronic equipment displays the multimedia resources, the electronic equipment displays the multimedia resources from the initial time of the non-displayed content, so that the continuity of displaying the multimedia resources is realized, the content of the multimedia resources is displayed as much as possible, and the watching effect of the multimedia resources is improved.
