[0045] In the embodiment of the present invention, in order to realize the interaction with children, when the vehicle-mounted system is in the open state, it can automatically detect the environment in the vehicle to detect whether there are child passengers in the vehicle; The child passenger corresponds to multimedia data with children's characteristics, wherein the multimedia data with children's characteristics can include various types, such as cartoons, nursery rhymes, and audiobooks, etc., which are not limited in this embodiment of the present invention . The multimedia data corresponding to the child passenger may refer to the multimedia data played by the child passenger last time, or the most frequently played multimedia data with children's characteristics, or all the multimedia data with children's characteristics in the database; etc. etc., which are not limited in this embodiment of the present invention. This further facilitates subsequent interaction with children based on the determined multimedia data with children's characteristics; for example, playing nursery rhymes, animations, etc., the embodiment of the present invention does not limit the specific form of interaction with children.

[0046] In the embodiment of the present invention, there are many ways to detect whether there is a child passenger in the car, for example, the pressure sensor corresponding to the rear seat is used to collect pressure information for detection, and another example is to call an image acquisition device in the car such as a high-definition camera to collect images. For the detection, for example, the information of the ISOFIX (International Standards Organization FIX, child safety seat fixing system) interface is obtained for detection, etc.; this is not limited in the embodiment of the present invention.

[0047] To sum up, in the embodiment of the present invention, it is possible to detect whether there is a child passenger in the car, and when it is determined that there is a child passenger in the car, it is possible to determine the multimedia data corresponding to the child passenger and having child characteristics; so that subsequent passengers can Interacting with the vehicle-mounted system based on the multimedia data with children's characteristics realizes the interaction between children and the vehicle-mounted system.

[0048] In another embodiment of the present invention, after determining the multimedia data corresponding to the child passenger and playing the voice prompt information with children's characteristics, the passenger can interact with the vehicle system based on the multimedia data, as follows:

[0049] refer to figure 2 , which shows a flow chart of steps in an optional embodiment of an interaction method of the present invention, which may specifically include the following steps:

[0050] Step 202, detecting whether there are child passengers in the vehicle.

[0051] In an implementation of the embodiment of the present invention, the child mode can be pre-configured for the vehicle system, and the corresponding trigger conditions can be set for the child mode. When the vehicle system detects that the vehicle environment meets the trigger conditions of the child mode, the child mode can be triggered Furthermore, after the child mode is triggered, the passenger can send a voice command to the on-board system, and correspondingly, the on-board system can receive the passenger's voice command and perform the operation corresponding to the voice command, thereby realizing the interaction between the on-board system and the child. Wherein, the children's mode may refer to a mode for interaction based on multimedia data with children's characteristics; the vehicle environment may include an in-vehicle environment or an out-of-vehicle environment, which is not limited in this embodiment of the present invention.

[0052] In an implementation of the embodiment of the present invention, the trigger condition corresponding to the child mode can be set as follows: there is a child passenger in the car; therefore, in the embodiment of the present invention, after the on-board system is started, it can automatically detect whether there is a child in the car Passengers; it is also possible to automatically detect whether there are child passengers in the vehicle after the on-board system remains on and detects that there are child passengers getting on and off the vehicle; this embodiment of the present invention is not limited. Among them, the camera inside the car and the camera outside the car can be used to collect images during the process of the vehicle changing from a stopped state to a driving state, and through image analysis, it is detected whether there are children passengers getting on and off the vehicle.

[0053] In the embodiment of the present invention, after the passenger sits on the seat, the pressure information collected by the seat pressure sensor will be greater than the pressure information collected when no passenger is seated on the seat, and the weight ranges corresponding to child passengers and adult passengers are different For example, the corresponding weight range for adult passengers can be >40kg, and the weight range for child passengers can be 10kg-30kg. Therefore, in an example of the present invention, a method of detecting whether there is a child passenger in the car may be to call the seat pressure sensor to obtain pressure information, and if the pressure information belongs to the pressure range of the child, it is determined that there is a child passenger in the car; Wherein, the seat pressure sensor may refer to the pressure sensor of the rear seat. Among them, the child's pressure range can be determined according to the weight range corresponding to the child passenger, and then the pressure information obtained by calling the seat pressure sensor can be compared with the child's pressure range to determine whether the pressure information belongs to the child's pressure range.

[0054] In the embodiment of the present invention, a child seat can be pre-installed on the seat of the vehicle, and then the child is allowed to sit on the child seat to enhance the protection of the child; therefore, in another example of the present invention, a detection vehicle The method of whether there is a child passenger in the car may be to obtain the status information of the ISOFIX interface of the child safety seat fixing system, and if the ISOFIX interface is determined to be connected according to the status information, then it is determined that there is a child passenger in the car.

[0055] In the embodiment of the present invention, the body shape and facial features of child passengers are different from those of adult passengers. Therefore, in another example of the present invention, a method of detecting whether there are child passengers in the car can be Yes, calling the image acquisition device to acquire image data, and if it is recognized that there is a child in the image data, it is determined that there is a child passenger in the vehicle; wherein, the image acquisition device may refer to an in-vehicle image acquisition device such as a camera. Wherein, it is possible to identify the persons in the image, analyze the facial features and/or body shapes of each person, and determine whether there is a child in the image.

[0056] Of course, it is also possible to combine at least two of the above-mentioned methods to detect whether there are child passengers in the vehicle, and when at least two of them are satisfied, it can be determined that there are child passengers in the vehicle; for example: when the pressure information belongs to child pressure range, and when it is determined that the ISOFIX interface is connected, it is confirmed that there are child passengers in the car. For another example, when the pressure information belongs to the pressure range of children, and it is recognized that there are children in the image data, it is confirmed that there are child passengers in the car. Also for example: when the pressure information belongs to the pressure range of children, and it is determined that the ISOFIX interface is connected, and it is recognized that there is a child in the image data, it is determined that there is a child passenger in the car; and so on. The embodiment of the present invention does not limit how many ways to combine to realize whether there is a child passenger in the vehicle.

[0057] Step 204, when it is determined that there is a child passenger in the vehicle, identify the child passenger.

[0058] In the embodiment of the present invention, the multimedia data that the child passenger may like can be determined based on the multimedia data played when the child passenger rides the vehicle, such as nursery rhymes, cartoons, etc.; Passengers recommend multimedia data that they may like. In addition, when a certain multimedia data has not been played completely during the child passenger's ride in the vehicle before, the multimedia data may continue to be played when the child passenger rides in the vehicle again. Therefore, in the embodiment of the present invention, when it is determined that there is a child passenger in the car, the child mode can be triggered, and then the identity of the child passenger can be identified to determine the identity information of the child passenger; Multimedia data corresponding to passengers.

[0059] Among them, the feature extraction can be performed according to the image collected by the image acquisition device, and then the extracted feature information is compared with the pre-stored feature information in the database; if there is pre-stored feature information matching the extracted feature information in the database, it can be determined If the identification of the child passenger is successful, the identity information corresponding to the matched pre-stored characteristic information may be determined as the identity information of the child passenger, and then step 206 may be executed. If there is no pre-stored feature information matching the extracted feature information in the database, it means that the identification fails, and step 208 can be executed at this time.

[0060] Step 206, if the identification is successful, search for multimedia data matching the identity information of the child passenger.

[0061] In the embodiment of the present invention, if the identification of the child passenger is successful, the multimedia data corresponding to the child passenger can be searched based on the identity information of the child passenger; The multimedia data that it may like can also search for the multimedia data played by the child passenger history, wherein the multimedia data played by the history is such as the multimedia data that has been played, or the multimedia data that has not been played last time; The multimedia data is determined to be multimedia data corresponding to the child passenger.

[0062] Step 208, if the identification fails, determine the preset multimedia data as the multimedia data corresponding to the child passenger.

[0063] In the embodiment of the present invention, if the identification of the child passenger fails, the preset multimedia data may be determined as the multimedia data corresponding to the child passenger; wherein, the preset multimedia data may be All multimedia data with children's characteristics may also be the top N (N is a positive integer) pieces of multimedia data with the highest playback frequency, etc., which is not limited in this embodiment of the present invention.

[0064] Step 210, playing the voice prompt information with characteristics of children.

[0065]In the embodiment of the present invention, after the child mode is triggered, voice prompt information with children's characteristics can also be played to remind passengers that they can interact with the vehicle system; the voice prompt information can include at least one of the following: welcome information, safety prompts Information and exchange guidance information; of course, other voice prompt information may also be included, which is not limited in this embodiment of the present invention. Among them, the welcome information can be used to improve the interaction experience of passengers, such as "cute, let's start a wonderful journey together!", "little baby, it's finally you!" To remind child passengers to ride safely, such as "cute, sit down obediently along the way!", etc.; the interactive guidance prompt information can be used to remind child passengers to interact, such as "little master, do you have any instructions?" , "Little master, I can sing, what nursery rhymes do you like to listen to?", "Little master, do you want to continue watching the last episode of "Peppa Pig"?", "Little master, do you want to listen to a nursery rhyme?" and many more.

[0066] Wherein, when the identification of the child passenger is successful, the voice prompt information matching the child passenger can be obtained from preset voice prompt information based on the identity information of the child passenger; When the identification of the passenger fails, the default voice prompt information can be obtained as the voice prompt information matched with the child passenger.

[0067] In addition, after the child mode is triggered, the ambient light in the car can also be changed; when the identity of the child passenger is successfully identified, based on the identity information of the child passenger, it can be obtained from the preset change mode of the ambient light. The changing mode of the ambient light matching the child passenger; when the identification of the child passenger fails, a default changing mode of the ambient light may be obtained as the changing mode of the ambient light matching the child passenger. Wherein, the changing manner of the ambient light includes but not limited to the changing manner of the color of the ambient light, the changing manner of on-off frequency of the ambient light, and the like.

[0068] In the embodiment of the present invention, if the passenger performs the control operation according to the played interactive guidance information, the vehicle-mounted system can receive the corresponding control command; then it can control the multimedia data corresponding to the control command, such as playing, switching, etc. Refer to steps 214-216. Wherein, the control operation may be voice control or manual touch screen control, which is not limited in this embodiment of the present invention. If the passenger does not perform the control operation according to the played exchange guidance information, step 212 may be executed.

[0069] Step 212: Display the multimedia data corresponding to the child passenger on the display device.

[0070] In the embodiment of the present invention, display information corresponding to multimedia data with children's characteristics can be displayed on a display device such as a vehicle display screen; wherein, the multimedia data with children's characteristics can include various types, such as cartoons, nursery rhymes, and Audiobooks and the like are not limited in this embodiment of the present invention. Wherein, the presentation information of the multimedia data may include multiple types, such as the cover, name, category, etc. of the multimedia data, which is not limited in this embodiment of the present invention. In an example of the present invention, such as image 3 As shown, the display device displays the display information of nursery rhymes, such as the categories of nursery rhymes such as "English enlightenment nursery rhymes", "50 widely sung nursery rhymes" and "ancient Chinese folk songs selection"; of course, the display device can also use other forms, The display information of the multimedia data is displayed, which is not limited in this embodiment of the present invention. It is convenient for passengers to view multimedia data with children's characteristics through the display device, and to interact based on the displayed multimedia data.

[0071] Step 214: Receive a control instruction for the multimedia data.

[0072] Step 216: Play the video data corresponding to the control instruction on the display device, and/or play the audio data corresponding to the control instruction in the zone corresponding to the child passenger.

[0073] In the embodiment of the present invention, after step 210 or after step 214, the passenger performs a corresponding control operation on the multimedia data; the corresponding on-board system can receive the corresponding control instruction, and then can follow the control instruction The corresponding multimedia data is controlled. Wherein, the video data corresponding to the control instruction can be played in the display device, and the audio data corresponding to the control instruction can also be played in the partition corresponding to the child passenger; for example, a cartoon can be played in the display device, and The audio corresponding to the cartoon is played in the zone corresponding to the child passenger, and for example, nursery rhymes, audio books, etc. can be played in the zone corresponding to the child passenger.

[0074] For example, if the passenger speaks the voice play command "play an English enlightenment nursery rhyme", after the vehicle system receives the voice play command, it can select a song such as "Hello Song" from all the nursery rhymes in the category of "English enlightenment nursery rhymes". , and then play the nursery rhyme "Hello Song" in the zone corresponding to the child passenger.

[0075] For another example, the passenger speaks out the voice play command "play "Peppa Pig", after the vehicle system receives the voice play command, it can select an episode from all the video collections of "Peppa Pig", and then display it on the display device. Play the video data of "Peppa Pig" on the Internet, and play the corresponding audio in the corresponding zone of the child passenger.

[0076] Of course, controlling the corresponding multimedia data according to the control instruction may also include other controls on the corresponding multimedia data; for example, switching of multimedia data, turning pages in the display device, pausing the multimedia data being played, and adjusting the volume of the multimedia data Etc., the embodiment of the present invention does not limit this.

[0077] To sum up, in the embodiment of the present invention, when it is determined that there are child passengers in the vehicle, the child mode is triggered, the multimedia data corresponding to the child passenger is determined, and the voice prompt information with child characteristics is played, the display device can display the The child passenger can display the corresponding multimedia data; it is also possible to receive the control instruction for the multimedia data with children’s characteristics, and then play the video data corresponding to the control instruction on the display device, and/or, in the child passenger The corresponding partition plays the audio data corresponding to the control instruction; thus realizing interaction with the child passenger.

[0078] Secondly, in the embodiment of the present invention, there are many ways to detect whether there are child passengers in the car. One method may be to call the seat pressure sensor to collect pressure information. If the pressure information falls within the pressure range of children, it is determined that there are children in the car. Passenger; another kind can be to obtain the status information of the ISOFIX interface of the child safety seat fixing system, if it is determined that the ISOFIX interface is connected according to the status information, then it is determined that there is a child passenger in the car; another kind can be called The image acquisition device acquires image data, and if it is recognized that there is a child in the image data, it is determined that there is a child passenger in the car; certainly, at least two of the above-mentioned judgments can be used to determine that there is a child passenger in the car; thereby improving the detection of whether there is a child in the car. passenger accuracy.

[0079] In another embodiment of the present invention, after identifying the child passenger and determining the corresponding seat belt interface connection of the child passenger, the vehicle-mounted system automatically adjusts the length of the seat belt of the child passenger; After finishing, interact with child passengers to strengthen the protection of child passengers.

[0080] refer to Figure 4 , showing a flow chart of the steps of another alternative embodiment of the interaction method of the present invention, specifically including the following steps:

[0081] Step 402, after determining that the seat belt interface corresponding to the child passenger is connected, if the identification fails, obtain the circumference information of the child passenger.

[0082] In the embodiment of the present invention, after the child mode is triggered and the identity of the child passenger is identified, it can be determined whether the seat belt interface corresponding to the child passenger is connected, and after determining that the seat belt interface corresponding to the child passenger is connected, it can automatically Adjust the seat belt corresponding to the child passenger. Wherein, if the identification fails, it can indicate that the child passenger has never been in the vehicle, and at this time the circumference information of the child passenger can be obtained, so as to adjust the length of the seat belt corresponding to the child passenger according to the circumference information. Wherein, the circumference information may refer to information used to characterize a child's body circumference, such as waist circumference information, shoulder width information, and the like.

[0083] In an example of the present invention, a manner of obtaining the circumference information of the child passenger may be to determine the weight information of the child passenger according to the pressure information, and determine the circumference information of the child passenger according to the weight information. Among them, the first circumference mapping relationship between weight information and circumference information can be established in advance, for example, (10kg-13kg)-circumference A1, (13kg-16kg)-circumference B1, (16kg-19kg)-circumference C1, (19kg~22kg)-circumference D1, (22kg~25kg)-circumference E1, (25kg~28kg)-circumference F1, (28kg~31kg)-circumference G1; of course, the first circumference mapping for each item The weight range in the relationship and the corresponding circumference information can be determined according to requirements, which is not limited in this embodiment of the present invention. Then, after determining the weight information of the child passenger based on the pressure information obtained by the pressure sensor and the relationship between the pressure information and the weight information; the first circumference mapping relationship can be searched based on the weight information of the child passenger to determine the weight information of the child passenger. Circumference information of the passenger; for example, it is determined that the weight information of the child passenger is 15kg, and by searching the first circumference mapping relationship, it can be determined that the circumference information of the child passenger is circumference B1.

[0084] In an example of the present invention, a method for obtaining the circumference information of the child passenger may be to determine the body shape characteristics of the child passenger according to the image data, and determine the circumference information of the child passenger according to the body shape characteristics; Wherein, the body shape feature may refer to information used to describe the passenger's fatness or thinness, such as thin, thin, normal, overweight, and fat. Among them, the second circumference mapping relationship between body shape characteristics and circumference information can be established in advance, such as thin-circumference A2, thin-circumference B2, normal-circumference C2, overweight-circumference D2, fat-circumference Girth E2; of course, the body shape characteristics and corresponding girth information in each second girth mapping relationship can be determined according to requirements, which is not limited in this embodiment of the present invention. After determining the body shape characteristics of the child passenger through image recognition, the circumference information matching the body shape characteristics of the child passenger can be searched based on the second circumference mapping relationship, and then the circumference information of the child passenger is determined; for example, determining The body shape characteristic of the child passenger is overweight, and by searching the second circumference mapping relationship, it can be determined that the circumference information of the child passenger is D2.

[0085] Certainly, in the embodiment of the present invention, the circumference information of the child passenger can be determined in combination with weight information and body shape characteristics; wherein, a third circumference mapping relationship between the weight information and body shape characteristics and the circumference information can be established in advance, for example : (10kg~13kg), lean—circumference A3, (10kg~13kg), normal—circumference B3, (13kg~16kg), overweight—circumference C3,……. Furthermore, after obtaining the weight information and body shape characteristics of the child passenger, the third circumference mapping relationship can be searched to determine the circumference information of the child passenger.

[0086] Step 404: Generate a corresponding first seat belt adjustment instruction according to the circumference information of the child passenger.

[0087] Step 406: Send the first seat belt adjustment command to the seat belt sensor corresponding to the child passenger, so that the seat belt sensor adjusts the length of the seat belt corresponding to the child passenger according to the first seat belt adjustment command.

[0088]Then, according to the circumference information corresponding to the child passenger, a first seat belt adjustment command can be generated, and the first seat belt adjustment command can be sent to the seat belt sensor corresponding to the child passenger; The belt adjustment command can be used to adjust the length of the seat belt, including the adjustment type information (releasing type information and tightening type information) and the adjustment length information of the seat belt. After the seat belt sensor receives the first seat belt adjustment instruction, it can obtain the adjustment type information and the corresponding adjustment length information of the seat belt from the first seat belt adjustment instruction; For the safety belt, adjust the corresponding adjustment length information according to the adjustment type information. For example, the adjustment type information included in the first seat belt adjustment instruction is tightening type information, and the adjustment length information is 2 cm, then the seat belt sensor tightens the seat belt length of the child passenger by 2 cm after receiving the instruction.

[0089] In an example of the present invention, a method of generating a corresponding first seat belt adjustment instruction according to the circumference information of the child passenger may include the following sub-steps:

[0090] Sub-step 22: Find the length mapping relationship based on the circumference information of the child passenger, and determine the target length information of the seat belt.

[0091] Sub-step 24: Generate a corresponding first seat belt adjustment instruction according to the target length information and current length information of the seat belt.

[0092] In the embodiment of the present invention, the length mapping relationship between the girth information and the length information of the safety belt can be established in advance, for example, girth A1—seat belt length L1, girth B1—seat belt length L2, girth C1—seat belt length L3. Then search the length mapping relationship based on the circumference information of the child passenger, determine the length information of the matching seat belt, and use the found length information of the seat belt as the target length information. Then the difference between the target length information of the seat belt and the current length information of the seat belt can be calculated; if the difference between the two is a positive number, it is determined that the seat belt needs to be relaxed, so the absolute value of the relaxation type and the difference can be used , to generate first seat belt adjustment information. If the difference between the two is negative, it is determined that the seat belt needs to be tightened, so the first seat belt adjustment information can be generated according to the tightening type information and the absolute value of the difference

[0093] Step 408: After determining that the seat belt interface corresponding to the child passenger is connected, if the identification is successful, search for matching seat belt length information based on the child passenger's identity information.

[0094] Step 410: Generate a second seat belt adjustment instruction according to the matched seat belt length information.

[0095] Step 412: Send the second seat belt adjustment command to the seat belt sensor corresponding to the child passenger, so that the seat belt sensor adjusts the length of the seat belt corresponding to the child passenger according to the second seat belt adjustment command.

[0096] In the embodiment of the present invention, after determining that the seat belt interface corresponding to the child passenger is connected, if the identification is successful, it means that the child passenger has ridden in the vehicle last time. The seat belt length information, and then generate a second seat belt adjustment instruction according to the matched seat belt length information. Wherein, the corresponding second seat belt adjustment instruction may be generated according to the matched seat belt length information and the current length information, which is similar to the above-mentioned sub-step 24 and will not be repeated here.
