DETAILED DESCRIPTION

[0021] Implementation Method 1

[0022] The following describes a first embodiment of the in-vehicle electronic device and electronic information output control method according to the present invention with reference to the accompanying drawings. In the specific embodiments, components of the device may be modified, deleted, or added, and the steps of the method may be modified, deleted, added, or reordered, depending on the actual situation.

[0023] like Figure 1As shown, the in-vehicle electronic device 100 is composed of a passenger detection unit 101, a passenger speech and behavior observation unit 102, a driver status acquisition unit 103, an obstructed driving judgment unit 104, a prompting unit 105 and other components. Figure 1 The in-vehicle electronic device 100 shown has the minimum configuration required to implement the present invention. The components 101-105 described above can be hardware components, such as any one or more of RAM / ROM memory, a DSP (Digital Signal Processor), and a CPU. The following describes in detail the necessary configuration required to implement the in-vehicle electronic device 100 of the present invention.

[0024] The passenger detection unit 101, comprised of a personnel detection component, a central processing unit, and a storage unit, detects the presence of passengers in the vehicle and determines whether there are any other passengers besides the driver. The personnel detection component includes, but is not limited to, a component capable of capturing images of the vehicle interior, such as a camera. If the personnel detection component is a camera, the camera captures the interior of the vehicle and transmits the captured images to the central processing unit, which analyzes and processes the images to detect the presence of any passengers in the passenger seat or rear seats. If so, the passenger is identified as a passenger. Alternatively, the personnel detection unit may utilize gravity sensors, etc., located on the corresponding seats, to detect the presence of passengers in specific parking spaces within the vehicle. This allows the determination of the presence of passengers in the passenger seat or rear seats. If so, the passenger is identified as a passenger. When the passenger detection unit 101 determines the presence of any passengers in the vehicle, it sends a signal to the passenger behavior observation unit 102.

[0025] The passenger speech and behavior observation unit 102 is composed of hardware such as a memory and a central processing unit. When receiving the information from the passenger detection unit 101 that there are other passengers in the car besides the driver, it observes the passenger's speech and behavior and further determines whether the passenger has performed the specified speech and behavior. Here, the speech and behavior in this case include but are not limited to the passenger's speech content, actions, behavior and other information. The specific speech content of the passenger is as follows: Figure 9A As shown in the figure, the specific actions and behaviors of the passengers are as follows: Figure 9B In addition, the specified speech and behavior information can be obtained by the user from the above Figure 9A , Figure 9B The setting can be selected from the passenger's speech and behavior database shown in , or it can be set by default by the manufacturer or developer of the device. In this embodiment, the specified speech and behavior information is as follows Figure 9A , Figure 9B When the above passenger speech and behavior observation unit 102 observes the speech and behavior of the passenger, it determines whether the passenger has done the following Figure 9A , Figure 9B The specific words and deeds shown in the database of passenger's words and deeds are judged. The specific judgment method here can be that the passenger's words and deeds observation unit 102 obtains and analyzes the two parts of information of the passenger's language and behavior respectively. Specifically, the language part can use the existing voice recognition technology to identify the passenger's speech content, which will not be elaborated here; the detection of the passenger's behavior part can first use a camera device to shoot the passenger's action information, and then use the central processing unit to analyze and judge the captured pictures or images to identify the passenger's action content. The above-mentioned specific analysis and identification of the passenger's words and deeds are not limited to the above-mentioned solutions. Other technologies that can analyze and identify the passenger's words and deeds can be included in this case. Then, after analyzing and identifying the passenger's words and deeds, the passenger's words and deeds observation unit 102 further compares the passenger's words and deeds information identified by the above analysis with the data in the above-mentioned specified words and deeds information database, that is, Figure 9A , Figure 9B Compare the data in the Figure 9A , Figure 9B According to the judgment result, when a fellow passenger sends Figure 9A , Figure 9B When the speech and behavior information specified in the above is obtained, the information is sent to the driver status acquisition unit 103. In addition, the passenger speech and behavior observation unit 102 can separately include a speech recognition unit for recognizing the speech of the passenger and a camera unit for recognizing the behavior of the passenger. The camera unit for recognizing the behavior of the passenger can also be the same unit as the camera in the passenger detection unit 101 that has the function of capturing images inside the vehicle.

[0026] Driver status acquisition unit 103, comprised of hardware such as a memory and a central processing unit, acquires driver status information upon receiving information from passenger behavior observation unit 102. Driver status information includes, but is not limited to, the driver's facial state, facial expression, emotional state, psychological state, and physiological indicators.

[0027] The obstruction determination unit 104, comprised of hardware such as a memory and a central processing unit, determines whether the passenger's words and actions obstruct the driver's driving based on the driver's status information acquired by the driver status acquisition unit 103. The specific determination method will be described in the subsequent detailed embodiments and will not be elaborated upon here. If the obstruction determination unit 104 determines that the passenger's words and actions do indeed obstruct the driver's driving, it sends a message to the prompt 105.

[0028] The prompting unit 105 is composed of components such as a memory, a speaker or a display. After receiving the information sent by the above-mentioned driving obstruction judgment unit 104, it sends a prompting message to reduce the driving interference to the above-mentioned driver.

[0029] Below, refer to Figure 2 A flowchart of a method for presenting information to a fellow passenger using an in-vehicle electronic device according to the present invention will be described.

[0030] First, the passenger detection unit 101 of the vehicle-mounted electronic device detects the situation of passengers in the vehicle (step S201) to determine whether there are other passengers in the vehicle besides the driver (step S202);

[0031] Then, according to the result of step S202, if it is determined that there are no other passengers in the vehicle except the driver (step S202: No), the process ends. If it is determined in step S202 that there are other passengers in the vehicle except the driver (step S202: Yes), step S203 is continued, that is, the passenger speech and behavior observation unit 102 further observes the speech and behavior of the detected passenger (step S203).

[0032] Next, during the observation process, the observed speech and behavior of the passenger is identified, analyzed, stored, and compared with the specified speech and behavior data to determine whether the passenger's speech and behavior contains the specified speech and behavior information (step S204);

[0033] Then, based on the result of step S204, if it is determined that the passenger's speech and behavior do not contain the specified speech and behavior information (step S204: No), the process returns to step S203. If it is determined that the passenger's speech and behavior do contain the specified speech and behavior information (step S204: Yes), the process continues to step S205, where the driver status acquisition unit 103 acquires the driver's status (step S205).

[0034] Next, based on the driver's status obtained in the above-mentioned step S205, the driving obstruction judgment unit 104 judges whether the words and deeds issued by the above-mentioned passenger interfere with the driver's driving (step S206); based on the execution result of step S206, when it is judged that the words and deeds issued by the above-mentioned passenger do not interfere with the driver's driving (step S206: no), the processing is terminated; when it is judged in step S204 that the words and deeds issued by the above-mentioned passenger do interfere with the driver's driving (step S206: yes), step S207 is continued to be executed, that is, information is issued to prompt the passenger to eliminate the interference of the above-mentioned passenger's words and deeds on the driver's driving (step S207).

[0035] This embodiment allows for monitoring the behavior of fellow passengers, assessing the driver's state after certain actions are taken, and determining whether these actions have an impact on the driver. Furthermore, if an impact does occur, timely and appropriate reminders can be provided to fellow passengers, thereby preventing the driver's state from deteriorating and distracting their attention, thereby reducing the risk of accidents.

[0036] Implementation Method 2

[0037] Next, a second embodiment of the present invention will be described in detail. Figure 3 This is a block diagram showing the configuration of an in-vehicle electronic device 100A according to a second embodiment of the present invention.

[0038] Here, components that are different from those of the in-vehicle electronic device 100 will be described in detail, and descriptions of the same components will be omitted.

[0039] The in-vehicle electronic device 100A is based on the in-vehicle electronic device 100 and further includes a physiological information abnormality determination unit 106 .

[0040] The physiological information abnormality determination unit 106 is composed of storage components and central processing components. It enables the driver status acquisition unit to obtain the driver's physiological information and then determine whether the physiological information is abnormal. Physiological information herein includes, but is not limited to, heart rate information, heartbeat information, respiratory rate, and breathing depth. This physiological information can be obtained through communication with an external device. That is, the physiological information abnormality determination unit 106 can also include a communication unit, such as a wristband, watch, or physiological monitor worn by the driver that can detect the driver's heart rate, heartbeat, respiratory rate, and other data, thereby obtaining the physiological information. Of course, the physiological information abnormality determination unit 106 can also directly include components that can detect the driver's heart rate, heartbeat, respiratory rate, and other data. In addition, the method for determining whether the physiological information is abnormal can be that if the value of any of the driver's physiological data is outside the normal range (the normal range for certain physiological values ​​defined in medical terms or generally accepted knowledge), the driver's physiological data is considered abnormal.

[0041] When the physiological information abnormality judgment unit 106 judges that the physiological information is abnormal, it sends information to the driving obstruction judgment unit 104. After the driving obstruction judgment unit 104 receives the information sent by the physiological information abnormality judgment unit 106, it believes that the above-mentioned words and deeds of the above-mentioned passenger have affected the psychological state of the above-mentioned driver, thereby interfering with driving, and then the prompt unit 105 sends a prompt information. For example, when the above-mentioned passenger words and deeds observation unit 102 detects that the passenger opens the window in the external environment of driving on a highway, the physiological information data of the driver is obtained, such as the heart rate is 150 beats / minute, which is more than the heart rate of an ordinary person. Therefore, it is considered that the driver's psychological information data is abnormal at this time, and the prompt unit 105 can prompt as follows: Figure 9B The driver can be prompted with the message "Sorry, opening the window here is dangerous, please close the window!" This prompt can be displayed on a screen visible to the passenger in the form of text or images, or in the form of voice to remind the passenger to correct the passenger's specific words and actions, thereby reducing or even eliminating the negative impact of the passenger's specific words and actions on the driver's driving.

[0042] Below, combined with the specific flow chart, that is, refer to Figure 4 The passenger information prompting method of the vehicle-mounted electronic device of this embodiment is described in detail. Steps S401 to S404 are Figure 2 Steps S201 to S204 are the same and are not described again here. Only the different contents, namely, steps S405 to S408, are described.

[0043] When the passenger speech and behavior observation unit 102 observes a specific speech or action of the passenger in step S404, the driver state acquisition unit 103 acquires the physiological information data of the driver (step S405);

[0044] Then, the physiological information abnormality determination unit 106 determines whether the physiological information of the driver is abnormal based on the physiological information data of the driver obtained in step S405 (step S406);

[0045] According to the judgment result of step S406, when the physiological information of the driver is within the normal range (step S406: No), the processing ends; when the physiological information of the driver is abnormal (step S406: Yes), step S407 is continued;

[0046] Furthermore, if it is determined in step S406 that the physiological information of the driver is abnormal, the driving obstruction determination unit 104 determines that the words and actions of the passenger have affected the driver, and such influence will interfere with the driver's driving (step S407);

[0047] Finally, a specific prompt message is sent to the fellow passengers to reduce or even eliminate the influence of the fellow passengers' specific words and deeds on the user (step S408).

[0048] This embodiment detects the driver's psychological state after observing specific actions from a fellow passenger. If the psychological state is abnormal, it is assumed that the specific actions have affected the driver, and the onboard electronic device can then provide a timely reminder to the fellow passenger. This allows for timely detection of changes in the driver's psychological state, preventing the impact of the passenger's actions on the driver's psychology, preventing accidents caused by deteriorating psychological information, and improving passenger safety.

[0049] Modification of the Second Embodiment

[0050] Next refer to Figure 5 The flowchart of the modified example of the second embodiment of the present invention is described in detail. Steps S601 to S604 are Figure 4 Steps S401 to S404 are the same and are not described again here. Only the different contents, namely, steps S605 to S609, are described.

[0051] When a specific speech or action of a fellow passenger is detected in step S604, the driver state acquisition unit 103 acquires the physiological information data of the driver's current state (step S605) and the history information of the driver's previous physiological information data (step S606);

[0052] Then, the physiological information abnormality determination unit 106 compares the current physiological information data of the driver and the historical information of the driver's physiological information data obtained in steps S605 and S606, respectively, to determine whether the current physiological information data of the driver is abnormal (step S607).

[0053] When the driver's current physiological information data is not significantly higher or lower than most of the driver's previous physiological information data (for example, significantly lower or higher than 50% of the physiological data), or is not significantly higher or lower than the average value of the driver's previous physiological information data, it can be determined that the driver's current physiological information data is normal (step S607: No), and the process ends;

[0054] On the contrary, that is, when the driver's current physiological information data is significantly lower or higher than most of the driver's previous physiological information data (for example, significantly lower or higher than 50% of the physiological data), or significantly higher or lower than the average value of the driver's previous physiological information data, it can be determined that the driver's current physiological information data is in an abnormal state (step S607: yes);

[0055] Next, if it is determined in step S607 that the driver's current physiological information is abnormal, the driving obstruction determination unit 104 determines that the passenger's speech or actions have affected the driver, and such influence will interfere with the driver's driving (step S608);

[0056] Finally, a specific prompt message is sent to the passenger to reduce or even eliminate the influence of the passenger's specific words and deeds on the driver (step S609).

[0057] Based on the second embodiment, this embodiment not only obtains the driver's current physiological information data, but also further integrates the driver's previous physiological information data, making the judgment of whether the driver's mental state is abnormal or not more accurate, further confirming the impact of the actions of fellow passengers on the driver, improving the accuracy and timeliness of this case, and ensuring the safety of passengers.

[0058] Implementation Method 3

[0059] Next, the third embodiment of the present invention will be described in detail. Figure 6 This is a block diagram showing the configuration of an in-vehicle electronic device according to a third embodiment of the present invention.

[0060] Here, as compared with the in-vehicle electronic device 100 , which is a configuration that minimally implements the present invention, components that differ from the in-vehicle electronic device 100 will be described in detail, and descriptions of the same components will be omitted.

[0061] The in-vehicle electronic device 100B is similar to the in-vehicle electronic device 100 and further includes an attention determination unit 107 .

[0062] The attention determination unit 107 is composed of a processor and a storage component, such as RAM / ROM. After the driver's attention state is obtained by the driver state acquisition unit 103, it is determined whether the driver's attention is not in a state of concentration. Specific determination methods include, but are not limited to, for example, the processor within the attention determination unit 107 can analyze an image and compare the image with driver big data or an attention distraction model to calculate; or it can also determine whether the driver's attention in the image is focused by analyzing whether the driver in the image performs a specified action, such as looking away from the driving direction or operating certain equipment in the vehicle.

[0063] The obstruction driving determination unit 104 determines, based on the determination result of the attention concentration determination unit 107 , that the words and actions of the fellow passenger interfere with the driver's driving when the driver's attention is not in a state of concentration.

[0064] Below, combined with the specific flow chart, that is, refer to Figure 7 This embodiment is described in detail. Steps S701 to S704 are Figure 2 Steps S201 to S204 are the same and are not described again here. Only steps S705 to S708 are described.

[0065] When a specific speech or action of a fellow passenger is observed in step S704, the driver state acquisition unit 103 acquires the driver's attention state information (step S705);

[0066] Then, the attention concentration determination unit 107 determines whether the driver is paying attention based on the physiological information data of the driver obtained in step S705 (step S706);

[0067] According to the judgment result of step S706, when the driver's attention is in a focused state (step S706: No), the processing ends; when the driver's attention is distracted (step S706: Yes), step S707 is continued;

[0068] Further, after it is determined in step S706 that the driver's attention has been diverted from driving, that is, when his attention is distracted from driving, the obstruction of driving judgment unit 104 believes that the passenger's language or actions have affected the driver's driving, and this influence will interfere with the driver's driving (step S707); for example, when the passenger turns up the audio volume very loudly, the driver will intentionally or unintentionally divert part of his attention to the plot of the video, and his eyes will deviate from the driving road, etc.

[0069] Finally, a specific reminder message is sent to the co-passenger to reduce or even eliminate the influence of the specific language or action issued by the co-passenger on the user (step S408). Figure 9B The prompt message "Sorry, your voice has disturbed the driver's driving, please turn down the volume!" is displayed.

[0070] By detecting the driver's driving concentration in this embodiment, it is determined whether the actions of fellow passengers have a negative impact on the driver's concentration. If a negative impact has occurred, the passenger can be promptly reminded of their words and actions to ensure the driver's concentration, avoid traffic accidents, and improve passenger safety.

[0071] Modification of the third embodiment

[0072] Next refer to Figure 8 The flowchart of the modified example of the third embodiment of the present invention is described in detail. Steps S801 to S804 are Figure 7 Steps S701 to S704 are the same and are not described again here. Only the different contents, namely, steps S805 to S809, are described.

[0073] When a passenger makes a specific speech or gesture in step S804, the driver state acquisition unit 103 acquires the driver's current attention state (step S805) and the driver's past attention state information (step S806);

[0074] Then, the attention determination unit 107 compares the driver's current attention state data and the driver's previous driving attention state data obtained in steps S805 and S806, respectively, to determine whether the driver's current driving attention state is abnormal (step S807).

[0075] When the driver's current driving concentration is not worse than the driver's previous driving concentration, it can be determined that the driver's current physiological data information is normal (step S807: No), and the process ends;

[0076] On the contrary, that is, when the driver's current driving concentration is worse than the driver's previous driving concentration, it can be determined that the driver's current driving concentration state is abnormal (step S807: yes);

[0077] Next, if it is determined in step S807 that the driver's current state of attention while driving is abnormal, the obstructed driving determination unit 104 determines that the passenger's speech or actions have affected the driver and that such influence will interfere with the driver's driving (step S808);

[0078] Finally, a specific prompt message is sent to the fellow passenger to reduce or even eliminate the influence of the fellow passenger's specific words and deeds on the driver (step S809).

[0079] By detecting the driver's current driving concentration and comparing the detection results with previous driver concentration, this embodiment can determine whether the driver's current attention is not focused, and thus further determine whether the words and actions of fellow passengers are affecting the driver's driving. Here, based on the third embodiment, the determination of attention can be made based on the user's own characteristics. This avoids the judgment errors caused by comparing the driver's driving concentration data with other people's driving concentration data or the average data of other people's driving concentration data, thereby improving the accuracy of the judgment of attention. It can timely remind passengers of their words and actions to ensure the driver's driving concentration, avoid traffic accidents, and improve passenger safety.
