[0072] The present application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the embodiments provided herein are only used to explain the present application and are not intended to limit the present application. In addition, the embodiments provided below are partial embodiments for implementing the present application, rather than providing all embodiments for implementing the present application. In the absence of conflict, the technical solutions recorded in the embodiments of the present application can be implemented in any combination.

[0073] Figure 1 The following is a diagram showing an application scenario of an information prompt method provided by an embodiment of the present application. Figure 1, when the first vehicle 101 is in motion or in a stationary state, the personnel in the first vehicle 101 may encounter a security threat event. When the first vehicle 101 is in motion, the first vehicle 102 may continue to follow the first vehicle 101 on a certain road section. After the first vehicle 101 arrives at a specific location, the personnel in the first vehicle 102 may suddenly commit violent acts and hijack the personnel in the first vehicle 101. When the first vehicle 101 is in a stationary state, for example, in a secluded parking lot, when the driver of the first vehicle 101 is a single woman, it is easy for the first vehicle 101 to be hijacked by the personnel 103 in the environment where the first vehicle 101 is located when the first vehicle 101 is in a stationary state.

[0074] In the related art, a driver monitoring system (DMS) and / or an advanced driving assistance system (ADAS) may be installed in the first vehicle 101. However, the related art cannot yet achieve the flexibility of the vehicle in responding to security threat events.

[0075] In order to solve the above technical problems, the present application provides an information prompting method and an electronic device. The information prompting method provided by the present application is described in detail below.

[0076] Figure 2 A schematic flow chart of the information prompt method provided in the embodiment of the present application is shown. Figure 2 The information prompt method provided in the embodiment of the present application can be implemented in the following manner:

[0077] Step A201: Obtain environmental characteristic information of the environment in which the first vehicle is located; the environmental characteristic information includes at least one of first state information of the first vehicle, second state information of the first target, and position information of the environment in which the first vehicle is located.

[0078] Here, the type of the first target may be a person in the environment where the first vehicle is located, or a vehicle in the environment where the first vehicle is located. The environment where the first vehicle is located may be any of the following environments: a road environment, a parking lot environment.

[0079] In the example, the first target is in the environment of the first vehicle, see Figure 1 The first transportation tool may be a first vehicle 101, and the first target may be a second vehicle 102 or a person 103 in the environment of the first transportation tool.

[0080] In an example, the first status information includes at least one of the number of drivers and passengers of the first vehicle, the gender of the drivers and passengers, the distance of the drivers and passengers from the first vehicle, and the moving speed of the first vehicle.

[0081] In practical applications, an image acquisition device may be disposed inside the first vehicle, and images of the interior of the first vehicle may be acquired using the image acquisition device. Image recognition may be performed on the images of the interior of the first vehicle to determine at least one of the number of drivers and passengers of the first vehicle and the gender of the drivers and passengers in the first status information.

[0082] It should be understood that the functions of the image acquisition device in the embodiment of the present application can also be implemented by the driver monitoring system.

[0083] In practical applications, a laser radar can be set on the top of the first vehicle to scan the environment in which the first vehicle is located. Based on the scanning results of the environment in which the first vehicle is located, at least one of the distance between the driver and passengers and the first vehicle and the moving speed of the first vehicle in the first status information is determined.

[0084] In an example, the second state information includes at least one of a distance between the first target and the first vehicle, a speed of the first target, and a duration for which the first target follows the first vehicle.

[0085] In practical applications, a laser radar can be set on the top of the first vehicle, and the laser radar can be used to scan the environment in which the first vehicle is located. Based on the scanning result of the environment in which the first vehicle is located, at least one of the distance between the first target and the first vehicle, the speed of the first target, and the duration of the first target following the first vehicle in the second state information is determined.

[0086] In an example, location information of an environment in which a first vehicle is located is obtained, and the location information includes at least one of historical safety status information of the environment in which the first vehicle is located and an environment type of the environment in which the first vehicle is located.

[0087] In practical applications, at least one of the historical safety status information corresponding to the location information and the environment type corresponding to the location information can be pre-stored in a database. The location information of the environment where the first vehicle is located is obtained using a global positioning system. According to the location information of the environment where the first vehicle is located, at least one of the historical safety status information of the environment where the first vehicle is located and the environment type of the environment where the first vehicle is located is queried in a database.

[0088] Step A202: Analyze at least one of the first status information, the second status information, and the position information to determine a first safety category of the driver and passenger of the first vehicle.

[0089] In the example, the first vehicle is provided with a processor, which analyzes at least one of the first state information, the second state information and the position information in real time, and determines the first safety category of the driver and passengers of the first vehicle according to the analysis result.

[0090] It should be understood that when the first vehicle is provided with a processor, the first vehicle can locally analyze at least one of the first state information, the second state information, and the location information. The display panel in the first vehicle presents the analysis result to the driver and passengers of the first vehicle, thereby improving the safety alert capability of the first vehicle.

[0091] In the example, the first vehicle is provided with a communication module, and the communication module is connected to a remote server. The communication module transmits at least one of the first state information, the second state information, and the position information to the remote server in real time. The remote server analyzes at least one of the first state information, the second state information, and the position information in real time, and determines the first safety category of the driver and passenger of the first vehicle according to the analysis result.

[0092] It should be understood that when the first vehicle is provided with a communication module, the remote server connected to the communication module can analyze at least one of the first state information, the second state information and the location information, and return the analysis result to the first vehicle. The analysis result is presented to the driver and passengers of the first vehicle to improve the safety alert capability of the first vehicle.

[0093] Step A203: Based on the operations corresponding to the various security categories, execute the operation corresponding to the first security category.

[0094] In the example, the first vehicle is provided with a memory, and operations corresponding to different safety categories are predefined in a database of the memory, and the operations corresponding to different safety categories include any of the following: issuing an alarm message, collecting video data, and collecting audio data.

[0095] It should be understood that based on classifying different security categories, establishing a correspondence between security categories and operations corresponding to the security categories, and executing operations corresponding to the first security category, the flexibility of the vehicle in responding to security threat events can be improved.

[0096] In the example, when it is determined that the safety category of the driver and passenger of the first vehicle is the first safety category, an operation corresponding to the first safety category is determined in a database according to the first safety category, and the operation corresponding to the first safety category is performed.

[0097] In practical applications, the first vehicle is provided with a processor, and the processor performs operations corresponding to the first safety category based on operations corresponding to each safety category, for example, sending an alarm message to the driver and passengers of the first vehicle or the public security department, and controlling the image acquisition device of the first vehicle to collect video data and / or audio data of the environment in which the first vehicle is located.

[0098] Based on the information prompt method provided by the present application, the environmental characteristic information of the environment in which the first vehicle is located is obtained; the environmental characteristic information includes at least one of the first state information of the first vehicle, the second state information of the first target, and the location information of the environment in which the first vehicle is located; therefore, at least one characteristic information in the environmental characteristic information can be analyzed according to the environmental characteristic information to determine the first safety category of the driver and passengers of the first vehicle. Different safety categories are classified, a corresponding relationship between the safety categories and the operations corresponding to the safety categories is established, and the operations corresponding to the first safety category are executed, so as to improve the flexibility of the vehicle in responding to safety threat events.

[0099] In practical applications, the above steps A201 to A203 can be implemented using a processor, and the above processor can be at least one of an application specific integrated circuit (ASIC), a digital signal processor (DSP), a digital signal processing device (DSPD), a programmable logic device (PLD), a field programmable gate array (FPGA), a central processing unit (CPU), a controller, a microcontroller, and a microprocessor.

[0100] In some implementations, in the above step A202, at least one of the first state information, the second state information, and the position information is analyzed to determine the first safety category of the driver and passenger of the first vehicle, which may be implemented in the following manner:

[0101] At least one of the number of drivers and passengers, the gender of the drivers and passengers, the distance of the drivers and passengers from the first vehicle, and the moving speed of the first vehicle is analyzed to determine a first safety category.

[0102] In the example, the first safety category is determined based on a comparison result between the number of drivers and passengers and a preset number of passengers; or, the first safety category is determined when the gender of the drivers and passengers meets a certain type of gender characteristics.

[0103] In an example, the first safety category is determined based on a comparison between a distance of the driver and the first vehicle and a first distance threshold; or, the first safety category is determined based on a comparison between a moving speed of the first vehicle and a first speed threshold.

[0104] In practical applications, the preset number of people and the first distance threshold recorded above can be pre-configured as parameter information by the driver and passengers of the first transportation vehicle. For example, a parameter configuration interface is provided to the driver and passengers on the display panel of the first transportation vehicle, and the parameter information input by the driver and passengers on the parameter configuration interface is obtained.

[0105] In some implementations, in the above information prompt method, at least one of the number of drivers and passengers, the gender of the drivers and passengers, the distance of the drivers and passengers from the first transportation means, and the moving speed of the first transportation means is analyzed to determine the first safety category, and the following implementation methods may be used:

[0106] If the number of drivers and passengers is lower than the target value, and / or the gender of the drivers and passengers is female, the distance of the drivers and passengers from the first means of transport is analyzed to determine the first safety category.

[0107] It should be understood that when the number of drivers and passengers is lower than the target value, and / or the drivers and passengers are female, the defense capabilities of the drivers and passengers of the first vehicle are limited, and the need for enhanced security alert is higher.

[0108] In this case, the distance between the driver and the first vehicle can be analyzed, and the first safety category can be determined based on the comparison result between the distance between the driver and the first vehicle and the first distance threshold, thereby improving the rationality of safety category classification.

[0109] In some implementations, in the above step A202, analyzing at least one of the first state information, the second state information, and the location information to determine the first security category includes:

[0110] At least one of a distance between the first object and the first vehicle, a speed of the first object, and a duration of time the first object follows the first vehicle is analyzed to determine a first safety category.

[0111] In the example, the first safety category is determined based on a comparison result of a distance between the first target and the first vehicle and a second distance threshold; or, the first safety category is determined based on a comparison result of a speed of the first target and a second speed threshold; or, the first safety category is determined based on a comparison result of a duration that the first target follows the first vehicle and a time threshold.

[0112] In practical applications, based on the at least one comparison result, a comprehensive evaluation may be performed on the at least one comparison result, thereby improving the safety and reliability of the analysis result.

[0113] In some implementations, in the above information prompt method, at least one of the distance between the first target and the first vehicle, the speed of the first target, and the duration of the first target following the first vehicle is analyzed to determine the first safety category, see Figure 3 , which can be implemented in the following ways:

[0114] Case 1: When the first target is a person, if the first target satisfies the first condition, it is determined that the first safety category is lower than the specific safety category.

[0115] Case 2: When the first object is a vehicle, if the first object satisfies the second condition, it is determined that the first safety category is lower than the specific safety category.

[0116] The following describes the case where the first target is a person and the case where the first target is a vehicle.

[0117] In the example, when the first target is a person, if the first target satisfies the first condition, it is determined that the first safety category is lower than the specific safety category. Here, the first condition may include at least one of the following: the distance between the first target and the first vehicle is less than a first distance threshold, the speed of the first target is greater than a first speed threshold, and the duration is greater than a first duration.

[0118] It should be understood that in any of the following cases: the distance between the first target and the first vehicle is less than the first distance threshold, the speed of the first target is greater than the first speed threshold, and the duration is greater than the first duration, the first target constitutes a following behavior of the driver and passengers in the first vehicle. In this case, it is necessary for the driver and passengers of the first vehicle to strengthen safety alertness.

[0119] In the example, a laser radar may be disposed on the top of the first vehicle, and the laser radar may be used to scan the environment in which the first vehicle is located, and the type of the first target may be determined based on the scanning result of the environment in which the first vehicle is located.

[0120] In actual applications, the laser built into the lidar emits a laser signal to the environment where the first vehicle is located. When the emitted laser signal encounters the first target, an echo signal is generated. Based on the detection of the echo signal, the distance between the first target and the first vehicle and the speed of the first target are detected.

[0121] In the example, an image acquisition device may be disposed on the top of the first vehicle, and the image acquisition device may be used to acquire an image of the environment in which the first vehicle is located, and image recognition may be performed on the image of the environment in which the first vehicle is located to determine the type of the first target.

[0122] In the example, when the first target is a vehicle, if the first target satisfies the second condition, it is determined that the first safety category is lower than the specific safety category. Here, the second condition includes at least one of the following: the distance between the first target and the first vehicle is less than the second distance threshold, the speed of the first target is greater than the second speed threshold, and the duration is greater than the second duration. Among them, the second distance threshold is greater than the first distance threshold, the second speed threshold is greater than the first speed threshold, and the second duration is greater than the first duration.

[0123] It should be understood that when the first target is a vehicle, the first target has high flexibility and maneuverability, and when the distance between the first target and the first vehicle is greater than the first distance threshold, the first target may still pose a safety threat to the driver and passengers in the first vehicle. Setting the second distance threshold to be greater than the first distance threshold can improve the safety and reliability of the analysis results.

[0124] In practical applications, based on the at least one comparison result, a comprehensive evaluation may be performed on the at least one comparison result, thereby improving the safety and reliability of the analysis result.

[0125] In some implementations, the above-mentioned information prompt method may also include the following implementation: when the first target is a vehicle, at least one of the second distance threshold, the second speed threshold and the second duration is determined based on at least one of the first state information and the position information.

[0126] In some implementations, in the above information prompt method, when the first target is a person, if the first target satisfies the first condition and it is determined that the first security category is lower than the specific security category, the following implementation may be adopted:

[0127] If the first vehicle satisfies the third condition, and the first object satisfies the first condition, it is determined that the first safety category is lower than the specific safety category.

[0128] In the example, the third condition includes at least one of the following: the number of drivers and passengers is less than the target number, the gender of the drivers and passengers is female, the distance of the drivers and passengers away from the first vehicle is on a decreasing trend, and the distance of the drivers and passengers away from the first vehicle is greater than the distance between the first target and the first vehicle.

[0129] In practical applications, based on the at least one recognition result, a comprehensive evaluation can be performed on the at least one recognition result, thereby improving the security and reliability of the analysis result.

[0130] In some implementations, in the above information prompt method, when the first target is a person, if the first target satisfies the first condition and it is determined that the first security category is lower than the specific security category, the following implementation may be adopted:

[0131] If the location information of the environment in which the first vehicle is located satisfies the fourth condition, and the first target satisfies the first condition, it is determined that the first safety category is lower than the specific safety category.

[0132] In an example, the fourth condition includes at least one of the following: the historical safety status information indicates that the environment in which the first vehicle is located is a dangerous environment, and the light intensity in the environment in which the first vehicle is located is lower than a light intensity target value.

[0133] It should be understood that when the first target meets the first condition, the first target constitutes a following behavior of the driver and passengers in the first vehicle, and the fourth condition reflects the natural environment of the location of the first vehicle. When the location information meets the fourth condition and the first target meets the first condition, it is necessary for the driver and passengers in the first vehicle to further strengthen safety alerts.

[0134] In some implementations, in the above information prompt method, when the first target is a vehicle, if the first target satisfies the second condition and it is determined that the first safety category is lower than the specific safety category, the following implementation may be adopted:

[0135] If the location information of the environment in which the first vehicle is located satisfies the fourth condition, and the first target satisfies the second condition, it is determined that the first safety category is lower than the specific safety category.

[0136] In an example, the fourth condition includes at least one of the following: the historical safety status information indicates that the environment in which the first vehicle is located is a dangerous environment, and the light intensity in the environment in which the first vehicle is located is lower than a light intensity target value.

[0137] It should be understood that in the case where the first target is a person or a vehicle, the first security category can be identified based on the parameters in the first condition and the second condition in the above-mentioned information prompt method, respectively, in combination with the fourth condition, to realize the function of security alert for different types of targets, thereby improving the flexibility of the vehicle in responding to security threat events.

[0138] In some implementations, the first state information includes the distance of the driver and the passenger from the first vehicle; the location information includes the risk factor of the environment in which the first vehicle is located; when the first target is a person, if the first target satisfies the first condition, it is determined that the first safety category is lower than the specific safety category, and the following implementations may be used:

[0139] If the risk factor of the environment of the first vehicle is greater than a preset factor, and the distance between the driver and the first vehicle is less than a first distance, and the distance between the first target and the first vehicle is less than a second distance, it is determined that the first safety category is lower than the specific safety category;

[0140] If the risk factor of the environment in which the first vehicle is located is less than or equal to the preset factor, and the distance between the driver and passengers from the first vehicle is less than the third distance, and the distance between the first target and the first vehicle is less than the fourth distance, it is determined that the first safety category is lower than the specific safety category; the first distance is greater than the third distance, and / or the second distance is greater than the fourth distance.

[0141] In practical applications, the first safety category is comprehensively evaluated based on the distance of the driver and passengers from the first vehicle, the risk factor of the environment in which the first vehicle is located, and the distance between the first target and the first vehicle, thereby improving the safety and reliability of the analysis results.

[0142] In some implementations, the location information includes at least one of historical safety status information of the environment in which the first vehicle is located and an environment type of the environment in which the first vehicle is located;

[0143] In the above step A202, at least one of the first state information, the second state information and the location information is analyzed to determine the first security category. Figure 4 , which can be implemented in the following ways:

[0144] Step A401: Analyze at least one of historical security status information and environment type to determine a first security category.

[0145] In the example, according to the location information of the environment where the first vehicle is located, at least one of the historical safety status information of the environment where the first vehicle is located and the environment type of the environment where the first vehicle is located is queried in a database.

[0146] In the above step A203, an operation corresponding to the first security category is performed, see Figure 4 , which can be implemented in the following ways:

[0147] Step A402: When the first security category is lower than the specific security category, perform at least one of the following operations: issuing an alarm message, collecting video data, and collecting audio data.
