[0001] The present invention relates to the technical field of vehicle function adjustment, and in particular to a method and device for adjusting a vehicle user interaction alarm threshold. Background Art

[0002] For vehicles equipped with an Advanced Driving Assistance System (ADAS), when the vehicle's driving state exceeds the safety range defined by the ADAS function, in order to protect the driving safety of the driver / passengers, the system will trigger an alarm signal, display an alarm message on the vehicle's display screen or provide the driver with an alarm message in other ways until the vehicle returns to normal driving state, and the user interaction alarm message will stop or disappear. Generally speaking, the threshold and / or conditions for triggering the ADAS user interaction alarm message are relatively fixed and cannot be freely adjusted, and are not applicable to all vehicle drivers.

[0003] Drivers may think that the threshold and / or conditions of user interaction warning information are not suitable for their own style.

[0052] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0053] It should be pointed out that the embodiments of the present invention and the technical features therein may be combined with each other without conflict.

[0054] Figure 1 FIG. 1 is a schematic diagram of the main steps of the method for adjusting the vehicle user interaction warning threshold according to an embodiment of the present invention. Figure 1 As shown, the vehicle user interaction warning threshold adjustment method of the embodiment of the present invention mainly includes the following steps S101 to S105:

[0055] Step S101, receiving an adjustment instruction for a user interaction warning threshold of a driving assistance function;

[0056] Step S102, when the driving assistance function is turned on, collecting video within a preset range corresponding to the key event;

[0057] Step S103, determining the target key event specified by the adjustment instruction among the key events;

[0058] Step S104, receiving a key frame selected by a user in a video of a target key event, and extracting the key frame from the video corresponding to the target key event;

[0059] Step S105 : taking the target control value corresponding to the target key event in the key frame as the user interaction alarm threshold of the target key event.

[0060] The initial user interaction warning threshold may have been set before the vehicle is mass-produced, and it supports user customization. In order to avoid frequent inquiries to the driver, the user interaction warning threshold adjustment function is disabled by default during the use of the vehicle. Once the user is dissatisfied with the initial user interaction warning threshold, the user interaction warning threshold adjustment instruction for the driving assistance function can be input in the vehicle's central control screen, the vehicle-related terminal, or an electronic device dedicated to the vehicle user interaction warning threshold adjustment. The adjustment instruction can also be input through voice interaction and other methods, so that the execution subject of the vehicle user interaction warning threshold adjustment method receives the adjustment instruction.

[0061] Here, the driving assistance function may refer to the driving assistance function used in the autonomous driving function levels L0 to L2, especially the driving assistance function with lane keeping assistance technology, and should have a user interactive alarm method.

[0062] When the adjustment instruction is received, it indicates that the user intends to adjust the user interaction alarm threshold for the driving assistance function, and the execution subject activates the function of adjusting the user interaction alarm threshold. Once it is detected that the current vehicle has turned on the driving assistance function, the video within the preset range corresponding to the key event is obtained. Here, the key event refers to the event in which the user interaction alarm exists in the driving assistance function of the vehicle. Since each key event has a different scope of concern and / or the original data input triggered, each key event is set with a different preset range, so the video within the preset range is collected for different key events. The videos within the preset range corresponding to the above-mentioned different key events can all be obtained by using a camera device pre-installed on the vehicle body, wherein the camera device pre-installed on the vehicle body can include several, and each camera device corresponds to a different distance range; the videos within the preset range corresponding to the above-mentioned different key events can also be displayed to the user using the auxiliary driving view; the videos within the preset range corresponding to the above-mentioned different key events can also be generated by the driving assistance function to display the road traffic facilities and other traffic participants. "Bird's-eye view".

[0063] It is worth noting that the preset range includes a preset time range and a preset distance range. The preset time range refers to the time period from the start of video acquisition to the stop of video acquisition. The preset time range can be pre-set before the vehicle is mass-produced, or it can be user-defined. The preset distance range refers to the distance extending from the current vehicle position as the center point to its surroundings. Similarly, the preset distance range can be pre-set before the vehicle is mass-produced, or it can be user-defined.

[0064] In addition, in order to avoid the execution entity from continuously storing the video, the above steps S101 to S105 are only valid within one ignition cycle of the vehicle. When the vehicle is turned off, once the user needs to adjust the vehicle user interaction alarm threshold again, the execution entity needs to re-receive the adjustment instruction input by the user before the user interaction alarm threshold adjustment function can be activated.

[0065] After acquiring the video, the target key event specified in the adjustment instruction can be determined. It is understandable that there is more than one key event with a user interaction alarm threshold in the driving assistance function. When the user inputs the adjustment instruction, the target key event for adjusting the user interaction alarm threshold should be determined among the key events with a user interaction alarm threshold in the driving assistance function. As an example, the key events with a user interaction alarm threshold in the driving assistance function include but are not limited to the distance of the current vehicle from the left lane line, the distance of the current vehicle from the right lane line, the distance of the current vehicle from the front vehicle, the distance of the rear vehicle from the current vehicle, the estimated collision time between the current vehicle and the front vehicle, etc.

[0066] The video corresponding to the target key event is played for the user. The user can select the key frame whose control value of the target key event meets his / her own needs in the video corresponding to the target key event, and the execution subject of the vehicle user interaction alarm threshold adjustment method extracts the key frame selected by the user from the video. Among them, the control value of the target key event includes a numerical value used for whether to perform a user interaction alarm for the target key event and / or other relevant numerical values ​​of the target key event. Then, the control value that meets the user's needs is selected in the key frame as the target control value of the target key event, and the target control value is used as the user interaction alarm threshold of the target key event, thereby achieving the effect of adjusting the user interaction alarm threshold of the target key event in the driving assistance function.

[0067] In the vehicle user interaction alarm threshold adjustment method of an embodiment of the present invention, the permission of customizing the user interaction alarm threshold is enabled for the vehicle user. The user can select the key frame whose control value of the target key event meets his or her own needs in the video containing the current vehicle position, and further select the target control value that meets his or her own needs from the control value as the user interaction alarm threshold. The function of customizing the user interaction alarm threshold is provided, which meets the vehicle use needs of different users and improves the driving experience.

[0068] In an optional embodiment, if Figure 2 As shown, before determining the target key event specified by the adjustment instruction, the method further includes steps S201 to S203:

[0069] Step S201, obtaining the status data of the current vehicle;

[0070] Step S202, analyzing whether the current vehicle meets the adjustment conditions according to the state data;

[0071] Step S203, when the current vehicle meets the adjustment conditions, a step of determining a target key event specified by the adjustment instruction is executed.

[0072] After acquiring the video of the key event, if the user needs to adjust the user interaction alarm threshold of the target key event based on the video, the adjustment conditions of the current vehicle need to be verified. Only when the adjustment conditions of the current vehicle are met will the step of determining the target key event and playing the video be entered.

[0073] Furthermore, the above-mentioned status data includes driving status;

[0074] The above analysis of whether the current vehicle meets the adjustment conditions includes:

[0075] When the driving status indicates that the current vehicle gear is in the parking gear, a prompt message is sent to indicate whether to adjust the user interaction alarm threshold; in response to receiving a trigger operation for the prompt message, when the trigger operation indicates confirmation of the adjustment, it is determined that the current vehicle meets the adjustment conditions.

[0076] When the current vehicle is in a non-parking gear, once the step of determining the target key event and playing the video for the user is entered, the user needs to be distracted to watch the video and cannot concentrate on driving the current vehicle, which may cause a traffic accident.

[0077] Therefore, in order to avoid driving safety issues, only when the current vehicle gear is in the parking gear, the above-mentioned execution entity will send a prompt message to the user whether to adjust the user interaction alarm threshold. When the user chooses to confirm the adjustment, the above-mentioned execution entity receives a trigger operation indicating confirmation of the adjustment. The current vehicle meets the adjustment conditions and enters the step of determining the target key event and playing the video for the user.

[0078] In an optional embodiment, if Figure 3 As shown, the above method also includes the following steps S301 to S302:

[0079] Step S301, determining a key event with a user interaction warning threshold in a driving assistance function;

[0080] Step S302, for each frame of the video corresponding to the key event, identify and obtain the control value of the key event at the corresponding moment, and mark the key event and the control value of the key event in each frame to provide a reference for selecting key frames; wherein the control value of the key event includes a numerical value used to determine whether to perform a key event user interaction alarm.

[0081] There may be multiple sub-functions, i.e., key events, in a driving assistance function. Not all key events require user interaction alerts. Therefore, it is necessary to determine the key events in the driving assistance function that support user interaction alerts, i.e., have user interaction alert thresholds.

[0082] During the process of collecting videos of key events or after the video is recorded, the above-mentioned execution entity can process each frame of the video based on the driving assistance function, and mark all key events involved in the current moment corresponding to the picture and their corresponding control values, so that users can timely understand the driving status at that time and provide data reference for users to select key frames for watching videos.

[0083] It should be noted that there may be different control stages for each key event, and the control conditions for each control stage are different, and the corresponding control values ​​are also different. Therefore, when marking the key events and their control values ​​for each frame in the video, the stage of the key event can be considered accordingly, and the control values ​​at different stages can be distinguished and marked based on the control conditions of the stage of the key event. The specific form of distinction can be achieved through font color, font size, text highlight color, etc., which are not limited here. As an example, when the key event is the distance between the current vehicle and the left lane line, there may be two stages. In the first stage, the distance between the current vehicle and the left lane line is greater than 30 cm and less than 40 m; in the second stage, the distance between the current vehicle and the left lane line is less than or equal to 30 cm. Then, when marking, it is possible to distinguish and mark according to the actual distance between the current vehicle and the left lane line in each frame. When the actual distance between the current vehicle and the left lane line in the picture is 35 cm, the control value of the actual distance between the current vehicle and the left lane line can be marked as 35 cm in yellow font; when the actual distance between the current vehicle and the left lane line in the picture is 30 cm, the control value of the actual distance between the current vehicle and the left lane line can be marked as 30 cm in red font, to indicate whether the distance between the current vehicle and the left lane line in the picture is in the first stage or the second stage, so that users can distinguish.

[0084] When the video is subsequently played for the user, the marked key events and the corresponding control values ​​should be displayed simultaneously. Here, the control value of the key event includes a value used to determine whether to perform a key event user interaction alarm, and may also include other relevant values ​​of the key event. As an example, when the key event is the distance between the current vehicle and the left lane line, the control value may include a value used to determine whether to perform a key event user interaction alarm, that is, the actual distance between the vehicle and the left lane line.

[0085] In addition to the control values ​​of the key events, the index information of the key events can also be marked in the picture. Here, the index information is the index information for the user to remember the key frames. In particular, it is easier for the user to remember the index information at the current moment in real time. As an example, the above index information can be count information that has no direct correlation with the key events and videos, or can be highlighted in different colors to facilitate the user to remember the key frames they want to select in real time.

[0086] In an optional embodiment, the above method further includes:

[0087] Identify whether the target control value corresponding to the target key event in the key frame is within a data threshold range;

[0088] When the target control value corresponding to the above-mentioned target key event is not within the above-mentioned data threshold range, a prompt message for reselecting the key frame is generated; when the target control value corresponding to the above-mentioned target key event is within the above-mentioned data threshold range, the target control value corresponding to the above-mentioned target key event in the above-mentioned key frame is used as the user interaction alarm threshold for the above-mentioned target key event.

[0089] Before using the target control value of the target key event in the key frame selected by the user as the user interaction alarm threshold of the target key event, the target control value of the corresponding target key event in the key frame should also be judged to identify whether it is within the data threshold range. Here, the data threshold range is the parameter optional range of the user interaction alarm threshold pre-set for each key event before the vehicle is mass-produced. In order to avoid the target control value of the key event selected by the user affecting the normal driving of the vehicle or easily causing a traffic accident, the data threshold range is pre-set. As an example, when the target key event indicated by the adjustment instruction is the distance between the current vehicle and the left lane line, its data threshold range is 15-35cm. If the target control value of the above target key event in the key frame selected by the user is 17cm, then 17cm can be directly used as the user interaction alarm threshold of the distance between the current vehicle and the left lane line; if the target control value of the above target key event in the key frame selected by the user is 13cm, then the user is prompted that the selected target control value is small and the key frame needs to be reselected, and the video is replayed for the user.

[0090] The vehicle user interaction alarm threshold adjustment method is described in detail below through a specific embodiment.

[0091] The present invention is implemented by taking the vehicle central control as the execution subject of the vehicle user interaction alarm threshold adjustment method as an example. Figure 4 As shown, the vehicle user interaction warning threshold adjustment method of the embodiment of the present invention includes:

[0092] Step S401, the vehicle central control receives an adjustment instruction from a user for a user interaction warning threshold of a driving assistance function; wherein the adjustment instruction indicates a target key event for the specified adjustment.

[0093] Step S402, the vehicle central control identifies whether the driving assistance function of the vehicle is turned on. If the driving assistance function is turned on, the video within the preset field of view corresponding to the key event is collected; if the driving assistance function is not turned on, the user is prompted to turn on the driving assistance function. After the driving assistance function is turned on, the video within the preset field of view corresponding to the key event is collected;

[0094] The vehicle central control determines the key events with user interaction alarm thresholds in the driving assistance function, such as key event 1: the distance between the current vehicle and the left lane line, key event 2: the distance between the current vehicle and the right lane line, key event 3: the distance between the current vehicle and the vehicle in front, key event 4: the distance between the rear vehicle and the current vehicle; in the process of collecting videos corresponding to the above four key events, the key event control value is marked for each frame of the video of each key event.

[0095] In step S403, the vehicle central control obtains the driving status of the current vehicle and determines whether the gear position of the current vehicle is in the parking gear. When it is in the parking gear, a prompt message is sent to the user to indicate whether to adjust the user interaction alarm threshold. When it is in a non-parking gear, the control returns to re-acquire the driving status until the current vehicle gear is in the parking gear, and then a prompt message is sent to the user to indicate whether to adjust the user interaction alarm threshold.

[0096] Step S404: When the vehicle control receives a trigger operation of confirming adjustment of the indication of the prompt information from the user, it is determined that the current vehicle meets the adjustment conditions; when the vehicle control receives a trigger operation of adjusting the indication of the prompt information later from the user, the driving state of the current vehicle is re-acquired after a period of time. Here, the period of time can be a preset time or an adjustment time selected by the user.

[0097] Step S405: Based on the adjustment instruction, determine the target key event indicated therein, such as the target key event being the distance between the current vehicle and the right lane line.

[0098] Step S406, the vehicle central control plays a video corresponding to the target key event and the control value of the target key event has been marked for the user, the user selects a key frame in the video of the target key event whose control value of the target key event meets his or her needs, and selects the target control value from the control value of the target key event in the key frame, and the vehicle central control extracts the key frame selected by the user from the video of the target key event.

[0099] Step S407, based on the target control value selected by the user in the control value of the target key event in the above key frame, the vehicle central control identifies whether the target control value of the target key event in the key frame is within the data threshold range corresponding to the preset target control value of the target key event. If the target control value of the target key event in the key frame is within the data threshold range, proceed to step S408; if the target control value of the target key event in the key frame is not within the data threshold range, the vehicle central control generates a prompt message to reselect the key frame and returns to step S406. As an example, the distance between the current vehicle and the right lane line in the key frame is 60cm, and the preset data threshold range of the distance between the current vehicle and the right lane line is 10cm-35cm. It is determined whether 60cm is within 10cm-35cm.

[0100] Step S408, if the target control value of the target key event in the key frame is within the data threshold range, the vehicle central control uses the target control value of the target key event in the key frame as the user interaction alarm threshold of the target key event.

[0101] As an example, continuing with the above example, since 60cm is not within the range of 10cm-35cm, the vehicle central control can generate a target control value for the distance between the current vehicle and the right lane line in the selected key frame that exceeds the optional range. Please reselect the prompt information of the key frame, and then return to step S406 to play the video for the user again.

[0102] Furthermore, the content of the prompt information may also include the data threshold range of the target key event, so that when the user reselects the key frame, he can compare the control value of the target key event in the selected key frame with its data threshold range, thereby further improving the adjustment efficiency of the user interaction alarm threshold.

[0103] As an example, if the user interaction alarm threshold of the distance between the current vehicle and the right lane line is 30cm before the vehicle is mass-produced, then when the distance between the current vehicle and the right lane line is greater than 30cm, no user interaction alarm will be issued; when the distance between the current vehicle and the right lane line is less than or equal to 30cm, a user interaction alarm will be issued. After the user adjusts the user interaction alarm threshold of the distance between the current vehicle and the right lane line, the adjusted user interaction alarm threshold is 60cm. When the distance between the current vehicle and the right lane line is greater than 60cm, no user interaction alarm is required, the user interaction alarm threshold symbol for this critical event will not appear on the vehicle's central control screen, and other components in the vehicle will not issue alarms for this critical event, or if Figure 5 As shown, a user interaction warning symbol appears, but no warning is given, all displayed by a green symbol; when the distance between the current vehicle and the right lane line is less than or equal to 60cm, as shown Figure 6 As shown, a user interaction warning symbol is displayed on the vehicle's central control screen. The warning is displayed in red, which has an obvious prompt effect. When a user interaction warning is given, other components in the vehicle can also give warnings at the same time, such as emitting buzzers, voice prompts, vibration prompts, etc.

[0104] The vehicle user interaction alarm threshold adjustment method of the embodiment of the present invention has the following advantages or beneficial effects: by obtaining a video containing the current vehicle position within a preset range, by extracting the user-selected key frame in the video, and using the target control value of the corresponding target key event in the key frame as the user interaction alarm threshold of the target key event, the user interaction alarm threshold is adjusted based on user needs, so that during vehicle driving, for users with higher psychological tolerance, the user interaction alarm will not appear too frequently and cause user distraction, or for users with lower psychological tolerance, the user interaction alarm will not appear too late and cause users to be unable to discover vehicle driving abnormalities in time, thereby meeting the vehicle use needs of different users and improving the driving experience.
