[0024] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0025] When the home security device is interconnected with the vehicle computer, the home security device can send alarm information to the vehicle computer through the server, so that the driver can understand the home security situation while driving the vehicle. However, the alarm prompt may cause the driver to be emotionally abnormal and distracted, thereby inducing a safety accident. In order to solve this problem, an embodiment of the present application provides a home security alarm method, in which the vehicle computer first determines whether the current vehicle usage scenario meets the alarm prompt condition before executing the alarm prompt, so as to ensure that the alarm information is provided in a safe scenario.

[0026] See also Figure 1 , Figure 1 This is a flow chart of a home security alarm method provided by an exemplary embodiment of the present application. The method is applied to a vehicle computer and includes the following steps.

[0027] Step 101, receiving the alarm information sent by the server, the alarm information is reported by the home security device when the home security device identifies the existence of security risks.

[0028] Optionally, the server is a cloud server. The home security device sends an alarm message to the cloud server, and then the cloud server forwards the alarm message to the vehicle computer bound to the home security device.

[0029] In a possible implementation, the home security device uploads the alarm information to a server in a first cloud corresponding to the home security device, the first cloud provided by the home security device manufacturer, for forwarding the alarm information to a second cloud corresponding to the vehicle computer, the second cloud provided by the vehicle computer service provider. Then, the server in the second cloud sends the alarm information to the vehicle computer.

[0030] Optionally, home security equipment has the function of identifying and reporting security risks. For example, when the home security equipment is a smart camera device, the smart camera device can perform image recognition on the monitoring screen, and send an alarm message to the server when a risk object (such as a fire, a fallen elderly person, etc.) is identified, so that the car computer can receive the alarm message sent by the server. For another example, a smart door sensor can push a door opening message when it detects a door opening action.

[0031] Optionally, the alarm information is used to characterize the security risks identified by the home security device, and may include the type of security risk that causes the risk to be reported, detailed alarm data, the time when the security risk occurs, the location where the security risk occurs, etc. The embodiments of the present application do not limit the specific content contained in the alarm information.

[0032] Step 102, when the vehicle is in use, determine the current vehicle usage scenario.

[0033] In some embodiments, the vehicle being in use refers to the state of the vehicle when the driver is controlling the vehicle to travel on a traffic road. Due to the complex traffic conditions, the driver needs to pay attention to the traffic conditions at all times. Therefore, when the vehicle is in use, the vehicle computer needs to determine whether to execute an alarm prompt based on the current vehicle usage scenario.

[0034] Step 103, when the current vehicle usage scenario meets the alarm prompt condition, an alarm prompt is issued based on the alarm information. The alarm prompt condition is a condition that needs to be met to issue an alarm prompt while ensuring the safe use of the vehicle.

[0035] In some embodiments, the warning prompt condition is used to determine whether the current vehicle use scenario is safe. Optionally, the warning prompt condition can be determined based on risk factors existing during vehicle use, such as vehicle speed, road type, driver status, traffic conditions, weather conditions, etc. Optionally, the vehicle use scenario can also be characterized by risk factors that easily affect vehicle use.

[0036] Optionally, the alarm prompt may be a text prompt, a voice broadcast, an indicator light indication, etc. The embodiment of the present application does not limit the specific prompt method of the alarm prompt.

[0037] When the home security device is connected to the vehicle computer, the home security device can send alarm information to the vehicle computer through the server, so that the driver can understand the home security situation while driving the vehicle. Since the alarm prompt may distract the driver and induce a safety accident, in the technical solution provided by the embodiment of the present application, the vehicle computer only executes the alarm prompt when the current vehicle usage scenario meets the alarm prompt conditions, which is conducive to ensuring driving safety during the alarm prompt.

[0038] In some embodiments, the vehicle usage scenario can be determined from two perspectives, including vehicle status and traffic status. Optionally, the vehicle computer can characterize the vehicle usage scenario through vehicle status information and traffic status information. Accordingly, the alarm prompt condition can also be divided into a first alarm prompt sub-condition and a second alarm prompt sub-condition, corresponding to the vehicle status information and the traffic status information, respectively.

[0039] See also Figure 2 , Figure 2 FIG. 1 is a flow chart of a home security alarm method provided by another exemplary embodiment of the present application. The process includes the following steps.

[0040] Step 201, receiving the alarm information sent by the server, the alarm information is reported by the home security device when the home security device identifies the existence of security risks.

[0041] The specific description of this step can refer to the above step 101, and the embodiment of the present application will not be repeated here.

[0042] Step 202: When the vehicle is in use, obtain vehicle status information and traffic status information.

[0043] In some embodiments, vehicle status information is used to characterize the current status of the vehicle, for example, driving data represented by signals transmitted between various functional modules in the vehicle, fault conditions of functional modules in the vehicle, historical driving trajectory of the vehicle and continuous driving time, and other vehicle information that can characterize the safety of the driver when currently using the vehicle. For further example, driving data may include data monitored by various functional modules such as throttle status, gear status, steering wheel grip status, and sensors, fault conditions may include low tire pressure, engine failure, etc., and historical driving trajectory and continuous driving time are positively correlated with the driver's fatigue level.

[0044] In a possible implementation, the vehicle status information is determined by monitoring signals from various functional modules and sensors within the vehicle, or by software on the vehicle computer based on driving data calculations.

[0045] In some embodiments, traffic status information is used to characterize the traffic conditions currently faced by the vehicle, such as traffic congestion, road conditions ahead and speed limit requirements, traffic route complexity, traffic section types, and other road traffic conditions.

[0046] In a possible implementation, the vehicle computer may determine traffic status information based on navigation information.

[0047] Step 203: determine the vehicle status information and traffic status information as the current vehicle usage scenario.

[0048] In some embodiments, by determining the current vehicle usage scenario, it can be determined whether there is a current safety risk. The safety risk may come from the vehicle itself or from the traffic scenario outside the vehicle. By determining the vehicle status information and traffic status information as the current vehicle usage scenario, it is helpful to comprehensively analyze the current safety situation.

[0049] Step 204: When the vehicle status information satisfies the first warning prompt sub-condition and the traffic status information satisfies the second warning prompt sub-condition, an alarm prompt is issued based on the alarm information.

[0050] In some embodiments, the first warning prompt sub-condition is used to determine whether the current vehicle state is safe, and the second warning prompt sub-condition is used to determine whether the current traffic state is safe. When the vehicle state information satisfies the first warning prompt sub-condition, and the traffic state information satisfies the second warning prompt sub-condition, both the vehicle state information and the traffic state information represent that the current vehicle usage scenario is safe, and the vehicle computer issues a warning prompt based on the warning information.

[0051] Optionally, the vehicle status information may include the vehicle speed and the vehicle geographic location, and the traffic status information may include the complexity of the traffic environment. The complexity of the traffic environment is positively correlated with the driver's attention needs. The higher the complexity of the traffic environment, the higher the probability of an accident caused by driver distraction. In addition, the vehicle speed is positively correlated with the driver's attention needs, and the accident rate of the geographic location is positively correlated with the driver's attention needs.

[0052] Based on the above reasoning, when the vehicle speed is less than the speed threshold, the vehicle's geographical location is outside the accident-prone area, and the traffic environment complexity is lower than the complexity threshold, the car computer will issue an alarm based on the alarm information to ensure that the driver has enough energy to respond to the alarm prompt, avoid causing abnormal driver emotions, causing driving errors, and leading to accidents.

[0053] Regarding the determination of the complexity of the traffic environment, in a possible implementation, the vehicle computer collects the external environment data according to the external sensor or camera device, and obtains the navigation information, and then inputs the external environment data and the navigation information into the traffic environment analysis model to obtain the traffic environment complexity output by the model. The traffic environment analysis model is trained based on sample external environment data, sample navigation information and sample traffic environment complexity.

[0054] In the embodiment of the present application, the vehicle usage scenario is specifically characterized by vehicle status information and traffic status information. The vehicle usage scenario is characterized from two perspectives: the vehicle itself and the traffic situation, which is beneficial to comprehensively reflect the safety situation of the current vehicle usage scenario; and the vehicle computer determines whether the vehicle status is safe and the traffic status is safe according to different alarm prompt sub-conditions. Only when both the current vehicle status information and the traffic status information meet the conditions, an alarm prompt is issued, which avoids distracting the driver's attention and is beneficial to ensuring driving safety.

[0055] Specifically, since the vehicle is located in an accident-prone area, the vehicle is traveling at a high speed, and the traffic environment is complex, the driver needs to concentrate. Therefore, the vehicle computer needs to execute warning prompts when the vehicle is traveling at a low speed, the vehicle is outside an accident-prone area, and the traffic environment is not complex, so as to improve driving safety during warning prompts.

[0056] In some embodiments, the vehicle computer issues an alarm when the vehicle usage scenario meets the alarm prompt conditions to ensure driving safety. However, the existence of the alarm prompt conditions may affect the timeliness of the alarm, that is, the vehicle computer may delay the alarm when the alarm prompt conditions are not met, resulting in missing the opportunity to respond to safety risks. In order to alleviate this problem, the vehicle computer can evaluate the safety risk level to ensure that the alarm information with a high safety risk level can be timely alarmed, and timely alarms can be achieved by setting appropriate alarm prompt conditions.

[0057] Among them, Figure 3 As shown, the process of determining the alarm prompt condition may include the following steps.

[0058] Step 301: determine the security risk level based on the warning information.

[0059] In some embodiments, the alarm information is used to characterize the security risk identified by the home security device. Optionally, the vehicle computer can determine the security risk level according to the type of security risk represented by the alarm information, for example, the security risk level corresponding to a fire is higher than the security risk level corresponding to a burglary. Optionally, the vehicle computer can also determine the security risk level according to the severity of the security risk represented by the alarm information, for example, the security risk level corresponding to a flame is lower than the security risk level corresponding to a large fire.

[0060] Optionally, the vehicle computer may determine the reference safety risk level corresponding to the reference warning information that matches the warning information as the safety risk level corresponding to the warning information based on the correspondence between the reference warning information and the reference safety risk level.

[0061] Step 302: determine an alarm prompt condition based on the security risk level, wherein different security risk levels correspond to different alarm prompt conditions, and different alarm prompt conditions include different first alarm prompt sub-conditions and second alarm prompt sub-conditions.

[0062] In some embodiments, high-risk safety risks have high requirements for the timeliness of warning prompts, and harsh warning prompt conditions easily lead to reduced timeliness of warning prompts. The vehicle computer needs to reduce the requirements of the warning prompt conditions for the safety of vehicle use scenarios. Low-risk safety risks have low requirements for the timeliness of warning prompts. The vehicle computer can increase the requirements of the warning prompt conditions for the safety of vehicle use scenarios to ensure driving safety during warning prompts.

[0063] Optionally, the safety risk level is negatively correlated with the degree of driving safety requirements represented by the warning prompt conditions, and is positively correlated with the degree of warning timeliness requirements, that is, the higher the safety risk level, the lower the safety requirements represented by the warning prompt conditions, and the higher the warning timeliness requirements; the lower the safety risk level, the higher the driving safety requirements represented by the warning prompt conditions, and the lower the warning timeliness requirements.

[0064] Optionally, the vehicle computer can store the correspondence between the safety risk level and the alarm prompt conditions, so as to determine the alarm prompt conditions according to the safety risk level. The vehicle computer can also adopt different calculation strategies according to different safety risk levels to determine the alarm prompt conditions that meet the driving safety and alarm timeliness requirements. The embodiment of the present application does not limit the specific method in which the vehicle computer determines the alarm prompt conditions according to the safety risk level.

[0065] Among them, when the vehicle status information and traffic status information are determined as the current vehicle usage scenario, the first warning prompt sub-condition that the vehicle status information needs to meet is different for different safety risk levels. Optionally, the safety risk level is negatively correlated with the degree of requirement for vehicle status safety of the first warning prompt sub-condition, and is positively correlated with the degree of requirement for alarm timeliness. Similarly, for different safety risk levels, the second warning prompt sub-condition that the traffic status information needs to meet is different. Optionally, the safety risk level is negatively correlated with the degree of requirement for traffic status safety of the second warning prompt sub-condition, and is positively correlated with the degree of requirement for alarm timeliness.

[0066] The following example uses vehicle status information including vehicle speed and vehicle geographic location, and traffic status information including traffic environment complexity as an example to illustrate the relationship between safety risk level and warning prompt conditions.

[0067] Exemplarily, when the vehicle speed is lower than the speed threshold and the vehicle is outside an accident-prone area, the vehicle status information satisfies the first warning prompt sub-condition. The safety risk level includes 1 to 5 levels from low to high. When the safety risk level is level 3, the speed threshold in the first warning prompt sub-condition is 30km / h, and when the safety risk level is level 4, the speed threshold in the first warning prompt sub-condition is 40km / h, which is higher than the speed threshold at level 3 risk, indicating that the first warning prompt sub-condition corresponding to a higher safety risk level has lower driving safety requirements, so as to improve the timeliness of the alarm.

[0068] Exemplarily, the traffic status information satisfies the second warning prompt sub-condition when the complexity of the traffic environment is lower than the complexity threshold. The complexity of the traffic environment includes levels 1 to 5 from low to high. Similar to the above example, when the safety risk level is level 3, the complexity threshold in the second warning prompt sub-condition is level 2, and when the safety risk level is level 4, the complexity threshold in the second warning prompt sub-condition is level 3. The complexity threshold higher than the level 3 risk indicates that the second warning prompt sub-condition corresponding to the higher safety risk level has lower driving safety requirements, so as to improve the timeliness of the alarm.

[0069] In an embodiment of the present application, the vehicle computer evaluates the safety risk level based on the alarm information so as to balance the driving safety and the timeliness of the alarm according to the safety risk level. This is specifically achieved by determining appropriate alarm prompt conditions according to the safety risk level. For example, a high safety risk level corresponds to loose alarm prompt conditions so as to issue a timely alarm, and a low safety risk level corresponds to strict alarm prompt conditions to ensure driving safety. This not only meets the alarm timeliness requirements, but also improves driving safety.

[0070] In some embodiments, when at least one of the vehicle status information and the traffic status information does not satisfy the warning prompt sub-condition, the vehicle computer postpones the warning prompt until the warning prompt sub-condition is satisfied, and then executes the warning prompt. In order to enable the vehicle status information and the traffic status information to satisfy the warning prompt sub-condition, the vehicle computer can provide a vehicle use prompt for situations where the relevant conditions are not satisfied.

[0071] See also Figure 4 , Figure 4 FIG. 1 is a flow chart of a home security alarm method provided by another exemplary embodiment of the present application. The method comprises the following steps.

[0072] Step 401, receiving the alarm information sent by the server, the alarm information is reported by the home security device when the home security device identifies the existence of security risks.

[0073] The specific description of this step can refer to the above step 101, and the embodiment of the present application will not be repeated here.

[0074] Step 402: When the vehicle is in use, determine vehicle status information and traffic status information.

[0075] Step 403: When the vehicle status information does not satisfy the first warning prompt sub-condition and / or the traffic status information does not satisfy the second warning prompt sub-condition, a vehicle use prompt is provided based on the unsatisfied warning prompt sub-condition.

[0076] In some embodiments, the vehicle use prompt is used to guide the vehicle driver to adjust the vehicle state and traffic state to a state that meets the first warning prompt sub-condition and the second warning prompt sub-condition by controlling the vehicle. Optionally, the vehicle computer can determine the method of satisfying the warning prompt sub-condition according to the unsatisfied warning prompt sub-condition. For example, when the vehicle speed in the vehicle status information is greater than the speed threshold, the vehicle computer prompts "there is a warning message, the current speed is too fast, please reduce the speed and understand the warning message". The vehicle computer monitors the vehicle speed in real time and issues a warning prompt when the vehicle speed is less than the speed threshold. For another example, the vehicle is located in an accident-prone area, and the vehicle computer prompts "there is a warning message, the current location is an accident-prone area, please drive to a safe area and understand the warning message". For another example, the vehicle is located in a complex traffic section, and the vehicle computer prompts "there is a warning message, the current location is a complex traffic section, please drive to an open and flat section or pull over to understand the warning message".

[0077] Optionally, the vehicle computer can monitor the vehicle status and traffic status in real time to determine the warning prompt sub-conditions that are not currently met, and provide vehicle use prompts. In a possible application scenario, the vehicle status information and traffic status information change in real time as the vehicle moves. After the vehicle computer guides the driver to adjust the vehicle status to meet the first warning prompt sub-condition through vehicle use prompts, the traffic status may change from meeting the second warning prompt sub-condition to not meeting the condition. The vehicle computer can provide vehicle use prompts again to ensure that both the vehicle status information and the traffic status information meet the warning prompt sub-conditions.

[0078] It should be noted that the vehicle use prompt does not involve the specific content of the safety risk to avoid affecting the driver's mood. The specific content of the safety risk is included in the subsequent warning prompt.

[0079] Step 404: When the duration of the vehicle use reminder does not reach the duration threshold, and the vehicle status information satisfies the first warning prompt sub-condition, and the traffic status information satisfies the second warning prompt sub-condition, a warning prompt is issued.

[0080] Step 405: When the duration of the vehicle use reminder reaches a duration threshold and there are unsatisfied warning reminder sub-conditions, a warning reminder is issued.

[0081] In some vehicle usage scenarios, the vehicle status information and traffic status information may always be difficult to meet the warning prompt sub-conditions. For example, when the first warning prompt sub-condition requires the vehicle speed to be less than 30km / h, and the vehicle is traveling on a highway with a minimum speed limit of 60km / h, the vehicle cannot reduce the vehicle speed to meet the first warning prompt sub-condition. Continuous vehicle use prompts may interfere with vehicle use, and may delay warning prompts and reduce the timeliness of warning prompts because the warning prompt sub-conditions are not always met.

[0082] To solve the above problem, in step 404 and step 405, the vehicle computer sets a time limit for the vehicle use reminder, and maintains the vehicle use reminder within the limited time. If the limited time is exceeded, even if the alarm prompt sub-condition is not met, an alarm prompt is still issued to ensure the timeliness of the alarm.

[0083] Optionally, the duration threshold is negatively correlated with the safety risk level represented by the warning information. Since different safety risks have different requirements for the timeliness of warning prompts, the higher the safety risk level, the more timely the warning is needed. Therefore, when the vehicle computer cannot use the vehicle use prompt to make the vehicle status and traffic status meet the warning prompt sub-condition, a shorter duration threshold is used to achieve timely warning.

[0084] However, in step 405, the vehicle computer performs the warning prompt when the warning prompt sub-condition is not met, and the problem of affecting driving safety still exists. In order to improve driving safety, the vehicle computer can optionally increase the safe driving assistance level within a preset time when the duration of the vehicle use prompt reaches a time threshold and there are unmet warning prompt sub-conditions.

[0085] In some embodiments, the vehicle may be equipped with a safe driving assistance system to prevent traffic accidents, such as an automatic parking system, an automatic emergency braking system, an adaptive cruise control system, etc. By improving the safe driving assistance level of the safe driving assistance system, driving safety can be guaranteed when the vehicle state and / or traffic state do not meet the warning prompt sub-conditions.

[0086] In a possible implementation, the vehicle computer increases the safety driving assistance level by increasing the number of safety driving assistance systems that are turned on. For example, when the vehicle use prompt duration reaches a threshold and there are unsatisfied warning prompt sub-conditions, the vehicle computer turns on all safety driving assistance systems and issues warning prompts.

[0087] In another possible implementation, the vehicle computer improves the safety driving assistance level by adjusting the auxiliary parameters of the safety driving assistance system. For example, the vehicle computer extends the following distance configured in the adaptive cruise system, or reduces the driving speed configured in the adaptive cruise system to ensure driving safety.

[0088] Since the time required for the car computer to issue an alarm is limited, after the alarm ends, the driver's attention returns to the use of the vehicle. The driver manually reduces the safety driving assistance level, which is inefficient and may cause the driver to be distracted. Therefore, if the preset time is exceeded, the car computer can automatically restore the safety driving assistance level.

[0089] In the embodiment of the present application, the vehicle computer prompts the vehicle status and traffic status to meet the warning prompt sub-conditions by executing the vehicle use prompt, thereby improving driving safety. In the case where the warning prompt sub-conditions are difficult to meet, the vehicle computer limits the duration of the vehicle use prompt to avoid the vehicle duration prompt from continuously interfering with the vehicle use and to avoid the warning prompt from being continuously delayed, which is conducive to improving the timeliness of the warning.

[0090] Among them, when the duration of vehicle use reminder reaches the duration threshold and there are unmet warning prompt sub-conditions, driving safety during the warning prompt is still difficult to guarantee. The vehicle computer improves driving safety by increasing the safety driving assistance level.

[0091] In some embodiments, the computing power of the home security device is limited, resulting in inaccurate security risk situations reported by the home security device. For example, when the home security camera device identifies the camera image, it may misreport the security risk due to recognition errors. Optionally, the alarm information sent by the home security device may include a security risk confidence level, which is used to characterize the analysis results of the home security device on its collected data. For example, the home security camera device determines that the probability of the existence of a fire by identifying the camera image is 48%, and the probability of the absence of a fire is 52%. Since the probabilities of the two situations are low and the recognition ability of the home security camera device may be insufficient, it remains to be further determined whether an alarm is required.

[0092] Optionally, the vehicle computer can improve the accuracy of determining safety risks through further safety risk identification.

[0093] See also Figure 5 , Figure 5 This is a flowchart of a home security alarm process involving security risk identification provided by an exemplary embodiment of the present application. The process includes the following steps.

[0094] Step 501, when the security risk confidence of the alarm information is lower than the confidence threshold and the current available computing power of the vehicle computer is greater than the computing power threshold, the alarm data associated with the alarm information is obtained from the server, and the alarm data is collected by the home security device and reported to the server.

[0095] In some embodiments, the alarm data is monitoring data of the home environment by the home security equipment, such as the camera images and audio data captured by the home security camera equipment, the temperature data measured by the temperature sensor, etc.

[0096] Among them, the vehicle computer determines that the alarm information reported by the intelligent security device has accuracy problems based on the fact that the security risk confidence level of the alarm information is lower than the confidence threshold.

[0097] Since the vehicle computer needs to use computing power to maintain vehicle operation, if the computing power of the vehicle computer is insufficient, the identification of safety risks may increase the burden on the vehicle computer, affect the vehicle computer's ability to handle vehicle operation-related events, and reduce driving safety. Therefore, the computing power of the vehicle computer needs to be greater than the computing power threshold to obtain alarm data and perform safety risk identification.

[0098] Step 502: Perform security risk identification based on the alarm data to obtain a security risk identification result.

[0099] In some embodiments, the security risk identification result is used to characterize whether there is a security risk. Optionally, in the case of a security risk, the security risk identification result may include the security risk type. For example, the security risk identification result may characterize the presence of a fire, the presence of a burglary, the presence of an elderly person falling, or the absence of a security risk.

[0100] Optionally, the vehicle computer has the ability to recognize alarm data. For example, when the computing power of the vehicle computer is sufficient to run an image recognition model, the vehicle computer can identify the camera images uploaded by home security cameras, determine whether there are security risks, and issue an alarm if it is determined that there are security risks.

[0101] Optionally, when the computing power of the vehicle computer is less than the computing power threshold, the vehicle computer can use the computing power of the server. After the server obtains the alarm data reported by the home security device, it performs security risk identification and obtains the security risk identification result. Then the vehicle computer receives the security risk identification result sent by the server.

[0102] Optionally, the identification method for security risk identification may include image recognition, audio recognition, behavior recognition, etc. The identification method may be consistent with the identification method adopted by the home security equipment, or may be inconsistent. This step does not limit the specific identification method.

[0103] Step 503: When the safety risk identification result indicates that there is a safety risk and the current vehicle usage scenario meets the warning prompt conditions, a warning prompt is issued based on the warning information.

[0104] Optionally, the alarm prompt condition may include a first alarm prompt condition and a second alarm prompt condition. When the vehicle computer determines the vehicle status information and traffic status information as the vehicle usage scenario, the vehicle status information needs to meet the first alarm prompt condition and the traffic status information needs to meet the second alarm prompt condition.

[0105] In the embodiment of the present application, since the computing power of the home security equipment is limited, when the confidence level of the security risk reported by the home security equipment is lower than the confidence threshold, the vehicle computer obtains the alarm data reported by the home security equipment from the server, so as to use its own computing power to identify the security risk, and then executes the alarm prompt when it is further determined that there is a security risk, thereby improving the accuracy of the alarm prompt. In addition, by ensuring that the computing power of the vehicle computer is greater than the computing power threshold, the security risk identification is avoided from interfering with the use of the vehicle, thereby further ensuring driving safety.

[0106] In some embodiments, during the warning process of the vehicle computer, a method for dealing with the current safety risk can be provided to improve the driver's decision-making efficiency, which is conducive to improving the efficiency of resolving safety risks.

[0107] See also Figure 6 , Figure 6 This is a flowchart of an alarm prompt process provided by an exemplary embodiment of the present application. The process includes the following steps.

[0108] Step 601, based on the alarm information, determine the alarm prompt information and processing method information.

[0109] In some embodiments, the warning information is the safety risk prompt content displayed by the vehicle computer to the driver. Optionally, the warning information may include detailed information such as the type of safety risk, the time of occurrence of the safety risk, the location of occurrence of the safety risk, etc., or may only prompt the type of safety risk, and determine whether to prompt detailed information according to the driver's instructions.

[0110] In some embodiments, the processing method information is associated with the safety risk and is used to provide a response strategy for the safety risk to prevent the driver from panicking. Optionally, the processing method represented by the processing method information may include calling for help and viewing monitoring data of home security equipment, such as viewing videos captured by home security camera equipment.

[0111] Optionally, the vehicle computer may store the corresponding relationship between the processing method and the safety risk type. For example, the processing method corresponding to a fire is to call the fire alarm, and the processing method corresponding to an elderly person falling is to call the emergency number. The safety risk type is included in the warning information.

[0112] Step 602: based on the alarm prompt information and the processing method information, play the alarm prompt voice and the processing method prompt voice.

[0113] The warning prompt voice is used to broadcast the content represented by the warning prompt information, and the processing method prompt voice is used to broadcast the content represented by the processing method information. The voice prompt can attract the driver's attention and improve the efficiency of the warning prompt.

[0114] Optionally, when the vehicle computer receives the processing method selection voice, it executes the operation corresponding to the processing method indicated by the processing method selection voice.

[0115] In an illustrative example, when the car computer determines that there is a fire, it broadcasts "A fire has been discovered at home. Should I check the video or call the fire alarm?" Subsequently, when the car computer receives instructions such as "make a call," "call 119," or "call the fire alarm," it establishes a Bluetooth connection with the communication device and calls the fire alarm. Optionally, the car computer can determine the processing method by calling a semantic recognition model or keyword matching. When the car computer determines that it has received a voice command to view the video, the video shot by the smart camera device is played on the car computer screen to understand the safety risk situation.

[0116] Optionally, when there are at least two processing methods, the processing method options can also be broadcast in the processing method prompt voice. For example, the vehicle computer broadcasts "Please select a fire processing method, one, call the fire alarm; two, check the monitoring screen." The vehicle computer receives the voice command, that is, one or two, and then executes the corresponding measures.

[0117] In an embodiment of the present application, the vehicle computer can broadcast warning prompts and recommended processing methods, receive voice for selecting processing methods, and execute the processing method indicated by the voice, which is conducive to attracting the driver's attention, improving prompt efficiency, and improving safety risk processing efficiency.

[0118] See also Figure 7 , Figure 7 This is a schematic diagram of an implementation of a home security alarm process provided by an exemplary embodiment of the present application. This embodiment uses a home security camera device as an example to illustrate the home security alarm process.

[0119] The home security camera device 701 first performs image recognition on the camera screen to determine that there is a fire, and reports the fire alarm information and monitoring screen to the server of the first cloud 702. The first cloud 702 sends the alarm information and monitoring screen to the second cloud 703, and then the server of the second cloud 703 sends the alarm information to the vehicle 704. Based on the alarm information, the vehicle 704 broadcasts "A fire has been found at home. Please check the video or call the fire alarm number", and receives the voice selection of the processing method. When the vehicle receives the voice command to call the fire alarm number, it connects to the communication device 705 via Bluetooth to call the fire alarm number. When it receives the voice command to view the video, it obtains the monitoring screen from the server and jumps to the monitoring page from the vehicle page.

[0120] The solution provided in the embodiment of the present application can avoid traffic accidents caused by abnormal driver emotions and improve driving safety during warning prompts.
