Description

A recorder for a vehicle, a method of recording a traffic event, and a vehicle having such a recorder TECHNICAL FIELD

[0001] The present invention relates to a recorder for a vehicle, a method of recording a traffic event, and a vehicle having such a recorder. BACKGROUND

[0002] With the increasing number of vehicles, especially cars, road traffic accidents occur frequently. As an important safety device, a driving recorder has gradually become a standard equipment for vehicles. The driving recorder continuously records video information during the driving process of a vehicle, and provides important evidence support for traffic accident liability identification, driving safety monitoring, and prevention of hit-and-run behavior. Current driving recorders usually have high-definition camera, night vision function, loop recording, gravity sensing, and parking monitoring functions, and are widely used in private cars, commercial vehicles, and public transportation vehicles. However, although the functions of the driving recorder are gradually improved, users still face some inconveniences in actual use.

[0003] One of the main problems is that when a video of a specific time period needs to be retrieved, the user often needs to manually browse a large number of video files. This not only consumes time and effort, but especially in the case of needing to quickly obtain relevant video evidence after an accident occurs, it is even more inconvenient. Most current driving recorders rely on file names or time stamps to find videos, but when faced with long recording content, it is still difficult to find a specific segment. In addition, it is also complex and time-consuming to mark specific events for current driving recorders. These limitations reduce the practicality of the driving recorder to some extent and affect the user experience.

[0004] Another problem is that when a traffic violation occurs, some serious vehicle violations are not captured due to the lack of monitoring equipment on some road sections. At this time, although there may be a driving recorder of a nearby vehicle that captures the corresponding picture, due to driving safety considerations, the corresponding violation cannot be timely sent to the traffic management department for follow-up, and thus the traffic accident cannot be timely handled and the traffic violation cannot be timely punished. SUMMARY

[0005] The present application aims to overcome the above problems and provides a recorder for a vehicle, a method for recording a traffic event and a vehicle with such a recorder. The recorder according to the present application comprises a shooting module, a storage module, an input module and a control module, wherein the shooting module converts a shot video into video data, the storage module is configured to store the shot video data, and the input module is configured to receive an operation input from a user. According to the present application, the control module is configured to, when the input module receives an operation input from a user, continue to record a subsequent time length of video and acquire a preceding time length of video that has been newly recorded (i.e. most recently recorded) in the storage module at the time when the operation input is received, and then store the preceding time length of video and the subsequent time length of video together as a total time length of video as a separate video or mark the total time length of video.

[0006] It should be understood that the total time length of video can be stored separately in an additional storage unit other than the storage module, or can still be stored in the storage module. Furthermore, the total time length of video stored in the storage module can be copied as an additional separate backup with respect to the originally recorded continuous video stream, or can not be copied as an additional separate backup, i.e. still remain in the originally recorded continuous video stream, but be marked by a specific event mark, so that it can be quickly identified and read separately in the future, i.e. the total time length of video can be quickly obtained from the originally continuous video stream.

[0007] Preferably, the total time length of video is uploaded and stored in a server. This can facilitate the user to quickly find the corresponding total time length of video at any time, e.g. at a non-driving time, especially when not in the vehicle, by accessing the server, without having to spend effort to find and locate the time period in which the corresponding event occurs.

[0008] Preferably, the server comprises a personal server or a commercial server, and / or a server for a public reporting platform provided by a traffic law enforcement department. By uploading to a personal server or a commercial server, such as a server of a social platform (e.g. WeChat), the user can access the video file through the application program corresponding to the server for real-time viewing, downloading or sharing. In this way, even if the user is not near the vehicle, the required video segment can be easily obtained. At the same time, the user can edit the corresponding video on, for example, a mobile terminal, so as to meet the requirements of the video format and the like of the docking interface of the public reporting platform provided by the corresponding traffic law enforcement department, thereby conveniently uploading it to the public reporting platform of the corresponding traffic law enforcement department. Alternatively, the total duration video can be directly uploaded to the server of the public reporting platform provided by the traffic law enforcement department without going through the social platform, which has been recorded according to the format and size and the like required by the public reporting platform before uploading, thereby greatly facilitating the reporting and punishment of part of the illegal behavior. The user can also obtain corresponding reporting rewards through the reporting behavior.

[0009] Preferably, the duration of the pre-sequence duration and / or the post-sequence duration can be adjustable according to different operation inputs of the user. For example, for illegal behavior of compacting lines, the time required for recording is shorter, so shorter pre-sequence duration and / or post-sequence duration can be recorded. For illegal behavior of running a red light at a wider crossroads or not turning at a traffic light, it may last for a long time, so a longer pre-sequence duration and / or post-sequence duration is recorded.

[0010] Preferably, the received operation of the user comprises voice operation, touch screen operation and / or key operation. In the case of voice operation, the user can choose to customize the video of a specific pre-sequence duration, post-sequence duration and / or total duration by voice input. For example, the user can directly input "record short video", "record medium video", "record long video" by voice. The duration of short video, medium video and long video can be pre-set. In addition, considering that sometimes the user has been in illegal behavior for a long time when inputting the instruction, the user can directly input, for example, the video recorded thirty seconds ago by voice.

[0011] In the case of key operation, the user can select the pre-sequence duration, post-sequence duration and / or total duration by the number of key presses and / or the duration of key press. Further preferably, in the case of key operation, the user can define the pre-sequence duration by the number of continuous key presses, and / or define the post-sequence duration by the holding time of the last key press.

[0012] For example, a short press of the input button once indicates recording a short video of 5 seconds. For example, the short video can include a pre-roll of 2 seconds and a post-roll of 3 seconds. For example, a short press of the input button twice indicates recording a medium video of 10 seconds. For example, the medium video can include a pre-roll of 3 seconds and a post-roll of 7 seconds.

[0013] Alternatively or additionally, the duration of the last press can determine or equal the post-roll. For example, a short press of the input button once and a long press of 10 seconds of the input button the second time, a video of 3 seconds pre-roll and 10 seconds post-roll, i.e. a total of 13 seconds, can be recorded. In this case, the sum of the number of long and short presses corresponds to the pre-roll.

[0014] In the case of touch screen operation, the user can select the pre-roll, the post-roll and / or the total duration by touch screen.

[0015] For example, in the case of touch screen operation, the user clicks on the touch screen to determine the reference time for recording, and / or the user defines the pre-roll by the magnitude of the forward drag on the touch screen, and / or the user defines the post-roll by the magnitude of the backward drag on the touch screen.

[0016] With these scenarios of operation, it is possible to quickly record videos of the desired duration in a way that hardly affects the driver's driving attention.

[0017] It should be understood that the user defined in the present application is not limited to the driver, other passengers can also record complete videos for specific events in a quick way by means of the device and method of the present application.

[0018] Preferably, the pre-roll is between 1 second and 10 seconds, and the post-roll is between 2 seconds and 20 seconds.

[0019] Preferably, after successful recording, the total duration video is directly uploaded to the server by default. Alternatively, the user's confirmation can be requested before uploading to the server. After receiving the user's confirmation, it is uploaded to the server. Alternatively, the user can be asked to confirm whether to send to the traffic law enforcement department. After receiving the user's confirmation, the video that meets the format and / or size of the reporting platform provided by the traffic law enforcement department is uploaded to the server of the reporting platform.

[0020] Although the relevant features and technical effects are discussed several times in this document with respect to traffic events, it should be understood by those skilled in the art that these features and technical effects can also be applied to any scenario that can be encountered during driving, such as other events occurring on both sides of the road.

[0021] The present application also relates to a method for recording a traffic event. The features and advantages discussed above in relation to the recording device also apply to the method for recording a traffic event. The method comprises the following steps:

[0022] In a first step, the input module receives an input from a user;

[0023] In a second step, the control module determines, based on the input from the user, a pre-sequence time length of the recorded video that needs to be rewound and a post-sequence time length that still needs to be recorded;

[0024] In a third step, the control module stores and / or identifies the video of the pre-sequence time length that has been recorded and the video of the post-sequence time length that is recorded after receiving the input from the user as a whole of a total time length video based on the determined pre-sequence time length and post-sequence time length.

[0025] The present application also relates to a vehicle comprising the recording device described above. The vehicle in the present application can be a motor vehicle that travels on a road, but can also be a non-motor vehicle such as a bicycle, etc., and can also be a rail vehicle, a water vehicle or an air vehicle. The features and advantages discussed above in relation to the recording device also apply to the vehicle comprising the recording device. BRIEF DESCRIPTION OF DRAWINGS

[0026] The preferred embodiments of the present application are explained in detail in the following with reference to the drawings. In which:

[0027] Fig. 1 shows a schematic diagram of the main modules of a recording device according to the present application.

[0028] Fig. 2 shows a main working flowchart of a recording device according to the present application. DETAILED DESCRIPTION

[0029] In order to enable a clearer understanding of the above-mentioned objects, features and advantages of the present application, the present application will be described in detail below with reference to the drawings and specific embodiments. It should be noted that the various embodiments of the aspects of the present application and the various features in the embodiments can be combined with each other as long as there is no conflict.

[0030] Fig. 1 shows a schematic diagram of the main modules of a recording device according to the present application.

[0031] In some embodiments, the recording device comprises a shooting module 101, a storage module 102, an input module 103 and a control module 104, wherein the shooting module 101 converts the shot video into video data, which can for example include an image sensor, a lens and related components; the storage module 102 is used to store the shot video data, which can for example be a memory integrated in the recording device and / or a removable memory card and / or cloud storage; the input module 103 is used to receive an operation input from a user.

[0032] In some embodiments, the control module 104 is configured to, when the input module 103 receives the operation input of the user, continue to record the subsequent time length of the video, and obtain the prequel time length of the video newly recorded in the storage module at the time of receiving the operation input, and then store the prequel time length of the video and the subsequent time length of the video together as a total time length video or mark the total time length video.

[0033] In some embodiments, the recorder only has a unique storage module 102, and the total time length video is stored in the storage module 102 as a copy together with the original video stream. In some variant embodiments, the total time length video does not exist in the form of a copy but in the form of a specific event mark in the original video stream, but the separate mark allows the user to quickly access and intercept the total time length video with the prequel time length and the subsequent time length. In some other embodiments, the total time length video is stored in an additional storage (not shown) other than the storage module 102.

[0034] In some embodiments, the recorder includes an upload module 105 that uploads the video to a server by communication for separate storage. The server can be located in the cloud, that is, the uploaded video is cloud-stored. The server can be a personal server or a commercial server 20, and / or a public reporting platform 30 provided by a traffic law enforcement department. In some embodiments, the commercial server is a server of a social platform such as WeChat, and the video is uploaded to the public reporting platform 30 of the traffic law enforcement department through the interface such as the public number provided by the traffic law enforcement department by the server of the social platform. Of course, in some variant embodiments, the upload module 105 can directly transmit the video to the public reporting platform 30.

[0035] In some variant embodiments, the upload module 105 of the recorder can not upload the total time length video to the server, but directly connect with the terminal of the user through a certain communication protocol and upload the required video to the terminal of the user for separate storage.

[0036] FIG. 2 shows the main working flowchart of the recorder according to the present application.

[0037] In the first step 1001, the input module 103 receives the input from the user. The input module 103 can be a voice receiving module, a touch screen, and / or a key.

[0038] In the second step 1002, the control module 104 determines the pre-sequence time length that the recording module 101 has recorded and the post-sequence time length that is yet to be recorded according to the user's input. In some embodiments, the pre-sequence time length and the post-sequence time length are predefined, i.e. already stored in the controller or the corresponding memory of the recording device. In some preferred embodiments, the control module 104 determines different pre-sequence time lengths and post-sequence time lengths according to different user inputs. The association between different user inputs and different pre-sequence time lengths and post-sequence time lengths is predefined in the controller or the memory of the recording device.

[0039] In the third step 1003, the control module 104 stores and / or identifies the video of the pre-sequence time length that has been recorded and the video of the post-sequence time length that is recorded after the user's input as a whole video of the total time length according to the determined pre-sequence time length and post-sequence time length. It should be appreciated that the "pre-sequence time length" and "post-sequence time length" referred to in the present application do not necessarily refer to independent video segments, but are defined for the purpose of distinguishing the pre-sequence time length of the video before the user's input and the post-sequence time length of the video.

[0040] In a preferred embodiment, the input module 103 is a touch screen. When the user clicks on the corresponding part of the touch screen, the user inputs the instruction to record the video. At this time, the user drags to the left in the touch screen to define the pre-sequence time length. The longer the dragging length, the longer the corresponding pre-sequence time length. The maximum dragging distance can correspond to the longest pre-sequence time length, for example, 10s. After dragging to the left, the user drags to the right in the touch screen to define the post-sequence time length. The longer the dragging length, the longer the corresponding post-sequence time length. The maximum dragging distance can correspond to the longest post-sequence time length, for example, 20s.

[0041] Therefore, the desired pre-sequence time length or post-sequence time length can be obtained by the following formula:

[0042] Desired pre-sequence time length = longest pre-sequence time length * actual left dragging distance / longest left dragging distance.

[0043] Desired post-sequence time length = longest post-sequence time length * actual right dragging distance / longest right dragging distance.

[0044] Wherein, the longest pre-sequence time length or the longest post-sequence time length has been predefined in the system or can be predefined; the longest left dragging distance or the longest right dragging distance can be defined by the touch screen.

[0045] In some embodiments, in the third step 1003, the separate storage of the total duration video can be stored in an additional storage unit (not shown) other than the storage module 102, or can still be stored in the storage module 102. In a further preferred embodiment, the total duration video is uploaded and stored into a personal or commercial server 20 or a public reporting platform 30 of the traffic law enforcement department by the uploading module 105, or uploaded to the public reporting platform 30 via the personal or commercial server 20.

[0046] Through the design of the recorder of the present application, the completeness, ease of operation and availability of the video recorded for the traffic event are significantly improved. On the one hand, the occupation of the user's attention during recording the video is reduced, and on the other hand, the efficiency and accuracy of traffic violation supervision are significantly improved. Compared with the traditional manual submission method, the process of the present application reduces the time delay, so that the law enforcement department can quickly obtain evidence and take action. In addition, the present application also improves the completeness and readability of the video when sharing on social media.

[0047] In addition, the uploaded video file combines key information such as time stamp, GPS position and vehicle speed, ensuring the completeness and non-tamperability of the evidence, enhancing the fairness of law enforcement, and the user can also obtain a reward for reporting in some situations. Finally, the road vehicle driving speed and safety can be effectively improved, and the habit of driving in a civilized manner can be improved.

[0048] As can be seen from the above, the present application improves the prior art and provides a recorder for a vehicle, a method for recording a traffic event and a vehicle, and achieves corresponding many advantageous technical effects with the above ideas. Although advantageous embodiments have been selected to illustrate the present application, those skilled in the art will understand that various changes and modifications can be made therein without departing from the scope of the present application as defined in the claims.
