[0021] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0022] Figure 1 FIG. 1 is a flow chart showing a first embodiment of a driving record method of the present invention, which is executed by a vehicle-mounted terminal. Figure 1 As shown, the method comprises the following steps:

[0023] Step 110: In response to the linkage trigger signal, a linkage recording instruction is sent to the mobile terminal, where the linkage recording instruction is used to instruct the mobile terminal to capture the first video and feed back.

[0024] Among them, the linkage trigger signal is a signal initiated when the linkage recording function is turned on; in actual applications, the linkage recording function can be automatically turned on when an emergency event is detected in the vehicle, or it can be turned on by the user (driver or passenger); it should be noted that the linkage recording function is a function of linking the vehicle-mounted driving recorder and the mobile terminal to record driving-related images.

[0025] Among them, the mobile terminal can be a mobile device such as a mobile phone, a smart watch, or a smart glasses; the linkage recording instruction is used to instruct the mobile terminal to capture a first video and feed the captured first video back to the vehicle-mounted terminal; it should be noted that the mobile terminal and the vehicle-mounted terminal can be connected in advance, and the mobile terminal grants the vehicle-mounted terminal permission to turn on the camera component of the mobile terminal according to the linkage recording instruction.

[0026] Specifically, when the vehicle terminal detects an emergency event in the vehicle, or the vehicle terminal responds to a linkage recording operation performed by the user, it initiates a linkage trigger signal, and based on the linkage trigger signal, sends a linkage recording instruction to the mobile terminal.

[0027] The mobile terminal receives the linkage recording instruction, turns on the camera component according to the linkage recording instruction, collects the first video through the camera component, and feeds back the collected first video to the vehicle-mounted terminal.

[0028] In an optional manner, before responding to a linkage trigger signal and sending a linkage recording instruction to the mobile terminal, it also includes: sending a connection request to the mobile terminal, the connection request is used to instruct the mobile terminal to display a connection page, the connection page displays text indicating establishment of a connection with the vehicle-mounted terminal, as well as a connection approval control and a connection rejection control, the connection approval control is used to establish a connection between the vehicle-mounted terminal and the mobile terminal when triggered; when a connection is established between the vehicle-mounted terminal and the mobile terminal, the mobile terminal can send a vehicle control instruction to the vehicle-mounted terminal, and the vehicle-mounted terminal can also synchronize vehicle-related data to the vehicle-mounted terminal.

[0029] When a connection is established between the vehicle-mounted terminal and the mobile terminal, the vehicle-mounted terminal can send a linkage request to the mobile terminal. The linkage request is used to instruct the mobile terminal to display an authorization page. The authorization page displays: text indicating authorization for the vehicle-mounted terminal to call the camera component based on the linkage recording instruction, as well as an authorization approval control and an authorization rejection control. The authorization approval control is used to authorize the vehicle-mounted terminal to call the camera component based on the linkage recording instruction when triggered.

[0030] Step 120: Receive a first video transmitted by a mobile terminal.

[0031] Specifically, the vehicle-mounted terminal receives the first video transmitted by the mobile terminal; in an optional manner, the mobile terminal can send the captured first video to the vehicle-mounted terminal after completing the first video capture, and the vehicle-mounted terminal receives the first video; in an optional manner, the mobile terminal can send the first video to the vehicle-mounted terminal in real time in the form of a video stream during the process of capturing the first video. When the mobile terminal stops capturing the first video, the mobile terminal stops sending the video stream, and the vehicle-mounted terminal obtains the complete first video based on the received video stream.

[0032] Step 130: Associating the first video and the second video according to the acquisition time to obtain a linked driving record video; the second video is collected by a vehicle-mounted driving recorder.

[0033] Among them, the on-board driving recorder can capture the second video in real time. In actual applications, when the on-board driving recorder is powered on, the on-board driving recorder can continue to capture the second video until the on-board driving recorder is turned off and stops capturing the second video; the on-board driving recorder can send the captured second video to the on-board terminal after stopping capturing; the on-board driving recorder can also synchronize the captured second video to the on-board terminal in real time through video streaming. When the on-board driving recorder stops capturing, the on-board terminal obtains the complete second video.

[0034] The acquisition time is used to indicate the time when a video (the first video or the second video) is acquired. The acquisition time may include a first acquisition time for acquiring the first video and a second acquisition time for acquiring the second video.

[0035] The linked driving record video is a video obtained by combining the first video and the second video, including the images obtained by the vehicle-mounted driving recorder and the images obtained by the mobile terminal. Compared with the second video or the first video, the linked driving record video contains richer information.

[0036] Specifically, the vehicle-mounted terminal receives the first video sent by the mobile terminal, and obtains the second video captured by the vehicle-mounted driving recorder, obtains the first acquisition time of the first video, and obtains the second acquisition time of the second video, and aligns the first video and the second video in acquisition time according to the first acquisition time and the second acquisition time, and integrates the first video and the second video after the acquisition time alignment to obtain a linked driving record video.

[0037] The vehicle-mounted terminal can save the first video, the second video and the linked driving record video in a local storage space.

[0038] In an optional manner, the vehicle-mounted terminal may connect the second video to the first video according to the acquisition time to obtain a linked driving record video.

[0039] In an optional manner, the vehicle terminal can also associate the video segment in the second video whose acquisition time is consistent with that of the first video to obtain a linked driving record video, so that during the process of playing the linked driving record video, when playing the video segment of the second video, the first video is played at the same time.

[0040] In an optional manner, the first video captured by the mobile terminal may be at least one. For example, after the user finishes the operation of capturing the first video on the mobile terminal and finds that some on-site content is missed, the user can continue to capture the next first video through the camera component and send the captured next first video to the vehicle terminal, so that the vehicle terminal obtains at least one first video. The vehicle terminal can associate the second video with at least one video according to the above manner to obtain a linked driving record video.

[0041] Exemplarily, when an emergency event of a vehicle is detected, such as a collision event of a vehicle, the vehicle-mounted terminal initiates a linkage trigger signal and sends a linkage recording instruction to the mobile terminal, so that the mobile terminal turns on the camera component to collect a first video. In the process of collecting the first video, the user can hold the mobile terminal and flexibly shoot the collision event scene from multiple angles to collect the content that the user wants to collect. The user can also adjust the shooting focal length of the mobile terminal to zoom in on the picture to capture the details of the key content, or zoom out on the picture to capture more information about the collision event, such as the lane conditions, ground conditions, and relative positions between the collision vehicles at the scene of the collision event, and can also zoom in on the details of the collision point of the vehicle; the picture recorded by the first video may be a picture that the vehicle-mounted driving recorder cannot capture; the mobile terminal sends the captured first video to the vehicle-mounted terminal, and the vehicle-mounted terminal associates the first video with the second video captured by the vehicle-mounted driving recorder to obtain a linkage driving record video, so that the linkage driving record video includes the picture captured by the vehicle-mounted driving recorder and the picture captured by the mobile terminal, thereby enhancing the information included in the driving record video.

[0042] In the above-mentioned driving recording method, the vehicle-mounted terminal instructs the mobile terminal to collect the first video and feedback through the linkage recording instruction. When the mobile terminal collects the first video, it can collect videos from multiple angles according to user needs. The vehicle-mounted terminal associates the first video with the second video collected by the vehicle-mounted driving recorder according to the collection time to obtain a linkage driving recording video. The linkage driving recording video includes the picture taken by the vehicle-mounted driving recorder and the picture taken by the mobile terminal. Compared with the second video taken by the vehicle-mounted driving recorder, the linkage driving recording video includes richer and more detailed information of the incident scene, thereby improving the richness and comprehensiveness of the linkage driving recording video.

[0043] In an optional manner, the driving recording method further includes: when it is detected that the driving state is an abnormal driving state, and / or a trigger instruction is received, initiating a linkage trigger signal.

[0044] Among them, the driving state of the vehicle belongs to an abnormal driving state, which means that the vehicle is not driving normally. For example, the acceleration of the vehicle exceeds the acceleration threshold, or the vehicle collides.

[0045] Specifically, the vehicle-mounted terminal can obtain relevant data about the vehicle's driving, determine the vehicle's driving status based on the relevant data, and judge whether the driving status is an abnormal driving status. If so, a linkage trigger signal is initiated.

[0046] The trigger instruction may be a voice instruction or an instruction triggered by a linkage button.

[0047] In an optional method, the user makes a voice, such as: "Turn on the linkage recording function", the vehicle terminal receives the voice and recognizes the trigger instruction, and then initiates the linkage trigger signal; it can be understood that the text corresponding to the voice instruction can also be other texts.

[0048] In an optional method, the user triggers the linkage button, causing the linkage button to switch from an off state to an on state, and then the vehicle terminal receives the trigger instruction and initiates a linkage trigger signal; in actual applications, the linkage button can be a physical button set in the car, and the linkage button can also be a virtual control displayed on the central control display screen in the car.

[0049] In an optional manner, when the vehicle-mounted terminal detects that the driving state is an abnormal driving state based on relevant vehicle driving data and receives a trigger instruction, a linkage trigger signal will also be initiated; that is, there are two trigger conditions: one is that the driving state is an abnormal driving state, and the other is that a trigger instruction is received. If one of the two is met, a linkage trigger signal can be initiated.

[0050] In the above embodiment, when it is detected that the vehicle is in an abnormal driving state, a linkage trigger signal can be automatically initiated, and then when the vehicle is in an abnormal driving state, the mobile terminal can immediately start collecting the first video, thereby improving the response speed of the linkage recording; and a linkage trigger signal can also be initiated when a trigger instruction is received, which can meet user needs in a timely manner and improve the flexibility of the linkage recording.

[0051] In an optional manner, the driving recording method also includes: acquiring driving data and sensor data of the vehicle, and determining the driving state based on the driving data and the sensor data; when the driving state is at least one of abnormal braking, abnormal acceleration or collision, determining that the driving state is an abnormal driving state.

[0052] The driving data may include but is not limited to: braking data and acceleration data; in practical applications, the braking data may include brake pedal opening data and vehicle deceleration; the acceleration data may include accelerator pedal opening data and vehicle acceleration. The sensor data may be data obtained by a collision sensor.

[0053] Specifically, the on-board terminal obtains the vehicle's real-time braking data, acceleration data and sensor data, determines whether the vehicle is in an emergency braking state through the braking data, determines whether the vehicle is in a sudden acceleration state through the acceleration data, and determines whether the vehicle has encountered a collision through the sensor data; if the braking data determines that the vehicle is in an emergency braking state, then the vehicle's driving state is determined to be abnormal braking; if the acceleration data determines that the vehicle is in a sudden acceleration state, then the vehicle's driving state is determined to be abnormal acceleration; if the sensor data determines that the vehicle has encountered a collision, then the vehicle's driving state is determined to be a collision; if the driving state is determined to be at least one of normal braking, abnormal acceleration or collision, then the vehicle's driving state is determined to be an abnormal driving state.

[0054] In practical applications, the abnormal driving state of a vehicle may be caused by a vehicle accident, or may lead to a subsequent vehicle accident. In the event of a vehicle accident, the driving record video can be used as evidence and submitted to relevant agencies for responsibility determination. In this case, a linkage trigger signal is initiated to facilitate the subsequent collection of the first video through the mobile terminal, and then the linkage driving record video can be obtained, which can improve the comprehensiveness and richness of the evidence, thereby making the responsibility determination more accurate and fair.

[0055] In the above embodiment, the vehicle-mounted terminal detects the driving status of the vehicle in real time, and automatically initiates a linkage trigger signal when the driving status of the vehicle is abnormal, so that the mobile terminal can immediately start collecting the first video, thereby improving the timeliness of collecting the first video and making the first video include richer information.

[0056] In an optional manner, after sending the linkage recording instruction to the mobile terminal, it also includes: sending real-time information of the vehicle to the mobile terminal, so that the mobile terminal adds the real-time information to the collected first video to obtain a first video including real-time information; the real-time information includes at least one of braking information, power information or battery information; receiving the first video transmitted by the mobile terminal, including: receiving the first video including real-time information transmitted by the mobile terminal.

[0057] Among them, the real-time information can be at least one of real-time braking information, power information or battery information. The real-time information can also include airbag deployment information, vehicle location information, vehicle identification (ID) and current time, etc.; braking information can include: brake pedal opening; power information can include engine power and / or engine torque; battery information can include remaining power.

[0058] Specifically, after the vehicle-mounted terminal sends a linkage recording instruction to the mobile terminal, it obtains real-time information of the vehicle and sends the real-time information to the mobile terminal. The mobile terminal obtains the first time corresponding to the real-time information, obtains the first video frame corresponding to the first time in the first video, adds the real-time information to the first video frame, obtains the first video including the real-time information, and sends the first video including the real-time information to the vehicle-mounted terminal.

[0059] Exemplarily, the real-time information obtained by the vehicle-mounted terminal includes the braking information and power information obtained at 12:00:01 and the braking information and power information obtained at 12:00:02; the vehicle-mounted terminal sends the real-time information to the mobile terminal, and the mobile terminal obtains the first video frame f1-1 acquired at 12:00:01 in the first video, and obtains the first video frame f2-1 acquired at 12:00:02; the braking information and power information acquired at 12:00:01 are added to the first video frame f1-1 to obtain the first video frame f1-2 with the real-time information added, and the braking information and power information acquired at 12:00:02 are added to the first video frame f2-1 to obtain the first video frame f2-2 with the real-time information added; the first video including the real-time information includes the first video frame f1-2 with the real-time information added and the first video frame f2-2 with the real-time information added.

[0060] It should be noted that in the above example, the number of video frames captured at a certain moment may be multiple, for example, the first video frame f1-1 captured at 12:00:01 may be multiple, for example, if the frame rate of the first video is 60FPS, the number of first video frames f1-1 may be 60.

[0061] In an optional manner, after receiving the first video transmitted by the mobile terminal, the vehicle-mounted terminal can obtain the real-time information corresponding to the first video frame in the saved real-time information based on the acquisition time of the first video frame in the first video, and add the real-time information corresponding to the first video frame to the first video frame to obtain the first video including the real-time information; that is, adding the real-time information to the first video can also be executed by the vehicle-mounted terminal.

[0062] In practical applications, the first video includes real-time information, which allows one to intuitively understand that the first video is strongly related to the vehicle, clarify the purpose and source of the first video, and enhance the credibility of the first video as accident evidence, while also increasing the amount of information included in the first video; the second video obtained by the on-board driving recorder may include real-time information. When the acquisition time of a first video frame in the first video and a second video frame in the second video is the same, the real-time information in the first video frame and the second video frame is also the same.

[0063] In an optional manner, if the second video acquired by the vehicle-mounted driving recorder does not include real-time information, the vehicle-mounted terminal may also add the real-time information to the second video according to the acquisition time to obtain the second video including the real-time information.

[0064] In the above embodiment, the real-time information of the vehicle (such as brake information, power information and battery information) is added to the first video collected by the mobile terminal to obtain the first video including real-time information. This can clarify the purpose and source of the first video, and can also enhance the credibility of the first video as accident evidence, while also increasing the amount of information included in the first video.

[0065] In an optional manner, the first video and the second video are associated according to the acquisition time to obtain a linked driving record video, including: obtaining the acquisition start time of the first video; obtaining a preceding video segment in the second video whose acquisition time is before the acquisition start time; and connecting the first video to the preceding video segment to obtain a linked driving record video.

[0066] Among them, the acquisition start time of the first video is the acquisition time corresponding to the first video frame in the first video; the acquisition time of the last video frame in the previous video segment is before the acquisition start time and adjacent to the acquisition start time.

[0067] Exemplarily, the first video is a video captured by a mobile terminal in the time period from 12:00:01 to 12:03:00, and the capture start time of the first video is 12:00:01; the second video is a video captured by a vehicle-mounted driving recorder in the time period from 11:30:00 to 12:05:00, and a preceding video segment before the capture start time is obtained in the second video, the preceding video segment being the video segment with a capture time of from 11:30:00 to 12:00:00 in the second video, and the first video is concatenated after the preceding video segment to obtain a linked driving record video; in this way, the linked driving record video includes the video captured by the vehicle-mounted driving recorder in the time period from 11:30:00 to 12:00:00, and the video captured by the mobile terminal in the time period from 12:00:01 to 12:03:00.

[0068] Accordingly, when playing the linked driving record video, after playing the preceding video segment determined in the second video, the first video continues to be played.

[0069] It should be noted that when a vehicle encounters an emergency, such as a collision, the on-board driving recorder can obtain the images around the vehicle during driving, and the collision position of the vehicle may not be within the field of view of the on-board driving recorder. Through the linkage recording method, users can flexibly shoot the content they want to show from multiple angles through the mobile terminal, such as the collision position, ground marks, etc. In the process of shooting the first video on the mobile terminal, the vehicle may have stopped, so the effective information in the video captured by the on-board driving recorder may be less. Therefore, the first video can be connected to the previous video segment to obtain a linked driving recording video.

[0070] In the above embodiment, the first video and the second video are associated in a continuous manner to obtain a linked driving record video, so that the linked driving record video can include the preceding video segment collected by the vehicle-mounted driving recorder before sending the linked recording instruction, and can also include the first video collected by the mobile terminal after sending the linked recording instruction. Compared with the second video taken by the vehicle-mounted driving recorder, the linked driving record video includes richer and more detailed information of the event scene, thereby improving the richness and comprehensiveness of the linked driving record video.

[0071] In an optional manner, a first video and a second video are associated based on acquisition time to obtain a linked driving record video, including: obtaining the linked acquisition period of the first video; obtaining a target video segment whose acquisition time is in the linked acquisition period and other video segments that are not in the linked acquisition period in the second video; establishing an association relationship between the first video and the target video segment in acquisition time based on the linked acquisition period; the linked driving record video includes other video segments, as well as the first video and the target video segment that are associated in acquisition time.

[0072] The linkage acquisition period is the time period for acquiring the first video, the target video segment is the video segment in the second video whose acquisition time is within the linkage acquisition period; and the other video segments are the video segments in the second video except the target video segment.

[0073] Specifically, the vehicle-mounted device obtains a time period (linked acquisition period) for acquiring the first video, and acquires a target video segment and other video segments in the second video according to the linked acquisition period.

[0074] For example, the first video is a video captured from 12:00:01 to 12:03:00, and the second video is a video captured from 11:30:00 to 12:05:00. It can be determined that the linkage capture period is from 12:00:01 to 12:03:00, and the target video segment is the video segment from 12:00:01 to 12:03:00 in the second video; the other video segments include: the video segment from 11:30:00 to 12:00:00, and the video segment from 12:03:01 to 12:05:00 in the second video.

[0075] For each acquisition time in the linkage acquisition period, the first target video frame corresponding to the acquisition time is obtained in the first video, and the second target video frame corresponding to the acquisition time is obtained in the target video segment, and an association relationship between the first target video frame and the second target video frame is established. In this way, the association relationship between the first video and the target video segment in terms of acquisition time can be established based on each acquisition time in the linkage acquisition period; and further, the linkage driving record video includes other video segments, the associated first video and the target video segment.

[0076] For example, in the above example, the linked driving record video includes: a video segment from 11:30:00 to 12:00:00, a video segment from 12:03:01 to 12:05:00 (other video segments), a first video and a target video segment that establish an association relationship during the period from 12:00:01 to 12:03:00.

[0077] It should be noted that the first video and the target video that are associated in acquisition time are used to synchronously play the first video and the target video according to the associated relationship in acquisition time when playing the linked driving record video.

[0078] Correspondingly, the driving recording method also includes: in response to the playback operation of the linked driving recording video, displaying the first playback area and the second playback area, playing the second video in the first playback area, and when playing the target video segment in the second video, synchronously playing the first video in the second playback area according to the correlation relationship in the acquisition time.

[0079] In the above embodiment, an association relationship is established between the first video and the target video segment, so that by linking the driving record video, the images captured by the vehicle-mounted driving recorder and the images captured by the mobile terminal at the same time can be determined, and then the environmental information of the vehicle and the content that the user wants to display can be synchronously displayed by linking the driving record video, thereby improving the richness of the driving record video.

[0080] Figure 2 FIG. 1 is a flow chart showing a first embodiment of a driving record method of the present invention, which is executed by a mobile terminal. Figure 2As shown, the method comprises the following steps:

[0081] Step 210: In response to the linkage recording instruction, the first video is captured by the camera component; the linkage recording instruction is sent by the vehicle terminal to the mobile terminal in response to the linkage trigger signal.

[0082] Among them, the linkage trigger signal is a signal initiated when the linkage recording function is turned on; in actual application, the linkage recording function can be automatically turned on when an emergency event is detected in the vehicle, or the linkage recording function can be turned on by the user.

[0083] Among them, the mobile terminal can be a mobile device such as a mobile phone, a smart watch, or a smart glasses; the linkage recording instruction is used to instruct the mobile terminal to capture a first video and feed the captured first video back to the vehicle-mounted terminal; the camera component can be the front camera or rear camera of the mobile terminal.

[0084] Specifically, when the vehicle terminal detects an emergency in the vehicle, or the vehicle terminal responds to a linkage recording operation performed by the user, a linkage trigger signal is initiated, and based on the linkage trigger signal, a linkage recording instruction is sent to the mobile terminal. The mobile terminal responds to the linkage recording instruction, turns on the camera component and displays a video acquisition page, and displays a real-time picture of the first video collected on the video acquisition page;

[0085] In an optional manner, the video capture page includes a camera component switching control; during the process of capturing the first video on the mobile terminal, the camera used to capture the first video can be switched through the camera component switching control. For example, when the front camera is currently used for shooting, the camera component switching control can be used to switch to the rear camera for shooting, or when the rear camera is currently used for shooting, the camera component switching control can be used to switch to the front camera for shooting.

[0086] Step 220: Send the collected first video to the vehicle terminal; the vehicle terminal is used to associate the first video and the second video according to the collection time to obtain a linked driving record video, and the second video is collected by the vehicle driving recorder.

[0087] Specifically, the video acquisition page includes an acquisition control, and the mobile terminal completes the acquisition of the first video in response to the operation on the acquisition control, and sends the acquired first video to the vehicle-mounted terminal.

[0088] In an optional manner, the mobile terminal responds to the operation on the acquisition control, completes the acquisition of the first video, and then sends the acquired first video to the vehicle terminal; in an optional manner, the mobile terminal can send the first video to the vehicle terminal in real time in the form of a video stream during the process of acquiring the first video. When the mobile terminal stops acquiring the first video in response to the operation on the acquisition control, the mobile terminal stops sending the video stream, and the vehicle terminal obtains the complete first video based on the received video stream.

[0089] In an optional manner, after the mobile terminal finishes capturing the first video, if the user still needs to capture the first video through the mobile terminal, the user can continue to capture the first video; after sending the captured first video to the vehicle-mounted terminal, the mobile terminal responds to the operation of the capture control, captures the first video through the camera component, and sends the first video to the vehicle-mounted terminal, so that the vehicle-mounted terminal associates the second video captured by the vehicle-mounted driving recorder with at least one first video captured by the mobile terminal to obtain a linked driving record video.

[0090] In an optional manner, after the vehicle-mounted terminal receives the first video fed back by the mobile terminal, if the user still needs to collect the first video through the mobile terminal, the user can also initiate a linkage trigger signal through the linkage button in the car or through a voice command, so that the vehicle-mounted terminal sends a linkage recording instruction to the mobile terminal again, and then the mobile terminal collects the first video again and feeds back, and the vehicle-mounted terminal can obtain at least one first video; the vehicle-mounted terminal associates the second video collected by the vehicle-mounted driving recorder with the at least one first video collected by the mobile terminal to obtain a linked driving recording video.

[0091] Regarding the process in which the vehicle-mounted terminal associates the second video with the first video to obtain a linked driving record video, please refer to the previous text and will not be repeated here.

[0092] In the above-mentioned driving recording method, the vehicle-mounted terminal instructs the mobile terminal to collect the first video and feedback through the linkage recording instruction. When the mobile terminal collects the first video, it can collect videos from multiple angles according to user needs. The vehicle-mounted terminal associates the first video with the second video collected by the vehicle-mounted driving recorder according to the collection time to obtain a linkage driving recording video. The linkage driving recording video includes the picture taken by the vehicle-mounted driving recorder and the picture taken by the mobile terminal. Compared with the second video taken by the vehicle-mounted driving recorder, the linkage driving recording video includes richer and more detailed information of the incident scene, thereby improving the richness and comprehensiveness of the linkage driving recording video.

[0093] In an optional manner, after capturing the first video through the camera component, it also includes: acquiring real-time information of the vehicle sent by the vehicle-mounted terminal, adding the real-time information to the captured first video, and obtaining a first video including real-time information; the real-time information includes at least one of braking information, power information or battery information.

[0094] Among them, the real-time information can be at least one of real-time braking information, power information or battery information. The real-time information can also include airbag deployment information, vehicle location information, vehicle identification (ID) and current time, etc.; braking information can include: brake pedal opening; power information can include engine power and / or engine torque; battery information can include remaining power.

[0095] Specifically, after the vehicle-mounted terminal sends a linkage recording instruction to the mobile terminal, it obtains real-time information of the vehicle and sends the real-time information to the mobile terminal. The mobile terminal obtains the first time corresponding to the real-time information, obtains the first video frame corresponding to the first time in the first video, adds the real-time information to the first video frame, obtains the first video including the real-time information, and sends the first video including the real-time information to the vehicle-mounted terminal.

[0096] Exemplarily, the real-time information obtained by the vehicle-mounted terminal includes the braking information and power information obtained at 12:00:01 and the braking information and power information obtained at 12:00:02; the vehicle-mounted terminal sends the real-time information to the mobile terminal, and the mobile terminal obtains the first video frame f1-1 acquired at 12:00:01 in the first video, and obtains the first video frame f2-1 acquired at 12:00:02; the braking information and power information acquired at 12:00:01 are added to the first video frame f1-1 to obtain the first video frame f1-2 with the real-time information added, and the braking information and power information acquired at 12:00:02 are added to the first video frame f2-1 to obtain the first video frame f2-2 with the real-time information added; the first video including the real-time information includes the first video frame f1-2 with the real-time information added and the first video frame f2-2 with the real-time information added.

[0097] It should be noted that in the above example, the number of video frames captured at a certain moment may be multiple, for example, the first video frame f1-1 captured at 12:00:01 may be multiple, for example, if the frame rate of the first video is 60FPS, the number of first video frames f1-1 may be 60.

[0098] In practical applications, the first video includes real-time information, which allows one to intuitively understand that the first video is strongly related to the vehicle, clarify the purpose and source of the first video, and enhance the credibility of the first video as accident evidence, while also increasing the amount of information included in the first video; the second video obtained by the on-board driving recorder may include real-time information. When the acquisition time of a first video frame in the first video and a second video frame in the second video is the same, the real-time information in the first video frame and the second video frame is also the same.

[0099] In the above embodiment, the real-time information of the vehicle (such as brake information, power information and battery information) is added to the first video collected by the mobile terminal to obtain the first video including real-time information. This can clarify the purpose and source of the first video, and can also enhance the credibility of the first video as accident evidence, while also increasing the amount of information included in the first video.

[0100] In an optional manner, the driving recording method can be applied to a scenario where a vehicle has an emergency. In this scenario, the mobile terminal is the driver's mobile phone, and a vehicle application is running on the mobile phone; Figure 3 Show.

[0101] The vehicle-mounted terminal sends a connection request to the mobile phone, and pre-establishes a connection between the vehicle-mounted terminal and the mobile phone through the vehicle application. The vehicle-mounted terminal sends an authorization request to the mobile phone, and the mobile phone authorizes the vehicle-mounted terminal to turn on the camera component of the mobile phone based on the linkage recording instruction; after completing the pre-connection and authorization, when the distance between the vehicle-mounted terminal and the mobile phone is within a preset range (indicating that the mobile phone is near the vehicle), the vehicle-mounted terminal and the mobile phone can use timed messages such as heartbeat signals to ensure that the connection status of both parties remains normal.

[0102] The vehicle-mounted terminal detects the vehicle's driving status through the vehicle's driving data and sensor data. When it detects that the driving status is an abnormal braking state, it initiates a linkage trigger signal. The vehicle-mounted terminal sends a linkage instruction to the mobile phone according to the linkage trigger signal. The mobile phone turns on the camera component and displays the video acquisition page in the vehicle application. The real-time picture of the first video collected is displayed on the video acquisition page.

[0103] In the process of capturing the first video through the mobile phone, the user can hold the mobile phone to capture the content that the user wants to record, for example, the user can flexibly shoot the surrounding scenes from multiple angles, and can also zoom in on the picture to capture the details of the key content, and zoom out on the picture to make it include more information, so as to capture the content that the user wants to capture; the video capture page displayed by the vehicle application includes a capture control, and the mobile phone responds to the trigger operation of the capture control to complete the capture of the first video and send the first video to the vehicle terminal.

[0104] The vehicle-mounted terminal receives the first video, and associates the first video with the second video captured by the vehicle-mounted driving recorder. Specifically, the vehicle-mounted terminal obtains the capture start time of the first video, obtains the preceding video segment whose capture time is before the capture start time in the second video, and connects the first video to the preceding video segment to obtain a linked driving record video; when playing the linked driving record video, after playing the preceding video segment, the first video continues to be played.

When the mobile terminal collects the first video, it can collect videos from multiple angles according to user needs.
