Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of vehicle safety, and in particular to a sentinel mode control method and device, an electronic device, and a storage medium. BACKGROUND

[0002] The sentinel mode is a vehicle safety function designed to prevent theft, vandalism, or other potential threats by monitoring the vehicle's surroundings.

[0003] A related sentinel mode control method generally acquires radar detection information by continuously detecting the surrounding environment using a millimeter wave radar on the vehicle, and then determines whether the vehicle meets the wake-up condition based on the acquired radar detection information. If the vehicle meets the wake-up condition, the control module enters a wake-up state. In the wake-up state, the radar detection information is used to determine whether the vehicle meets the collection condition. When the vehicle meets the collection condition, the image collection device is controlled to collect the vehicle's surrounding environment, thereby starting the sentinel mode.

[0004] However, the above method mainly relies on a single sensor, i.e., the millimeter wave radar. If the millimeter wave radar fails to work normally due to a fault or environmental interference (such as rain, snow, fog, etc.), it may cause the sentinel mode to be incorrectly triggered or triggered by mistake. In addition, continuously running the millimeter wave radar and the image collection device consumes a lot of vehicle energy. Therefore, the related sentinel mode control method has the problems of low accuracy of sentinel mode triggering and high energy consumption. SUMMARY

[0087] Exemplary embodiments of the present application will be described in detail with reference to the drawings. Although exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present application can be more thoroughly understood and so that the scope of the present application can be completely conveyed to those skilled in the art.

[0088] The sentinel mode control method, device, electronic device and storage medium provided by an embodiment of the present application will be described in detail below with reference to the drawings, specific embodiments and application scenarios.

[0089] Please refer to Figure 1 , Figure 1 is a system architecture schematic diagram for implementing a sentinel mode control method provided by an embodiment of the present application.

[0090] The system architecture is arranged on a vehicle, as shown in the figure, which can include an elastic wave sensor, an elastic wave controller, a TBOX (Telematics BOX, a vehicle Internet terminal), a millimeter wave radar, a cabin domain controller, a camera (which can also be a multifunctional camera), and a gateway. Figure 1

[0091] Figure 2 A step flow chart of a sentinel mode control method provided by the present application is shown in the figure, which includes the following steps: Figure 2

[0092] Step 201: In the case of starting the sentinel mode of the vehicle, the elastic wave signal is detected by the elastic wave sensor, wherein the elastic wave signal is the signal formed when the object touches the vehicle.

[0093] Step 202: Determine the touch position and touch force between the object and the vehicle according to the elastic wave signal.

[0094] Step 203: Send the touch position and touch force to the vehicle Internet terminal.

[0095] Step 204: In the case of receiving the touch position and touch force by the vehicle Internet terminal, control the millimeter wave radar to start.

[0096] In some embodiments of the present application, the sentinel mode can be started in advance at the vehicle APP (Application, application) end. When the object touches the vehicle, the elastic wave signal will be generated, and the elastic wave sensor can detect the generated elastic wave signal. Therefore, in the case of starting the sentinel mode of the vehicle, the elastic wave signal can be continuously detected by the elastic wave sensor installed on the vehicle.

[0097] In the case of detecting the elastic wave signal by the elastic wave sensor, the touch position and touch force between the object and the vehicle can be determined according to the generated elastic wave signal, and the touch position and touch force of the object are sent to the vehicle Internet terminal.

[0098] In the case of receiving the touch position and touch force of the object by the vehicle Internet terminal, the vehicle Internet terminal sends a wake-up signal to the gateway. In the case of receiving the wake-up signal sent by the vehicle Internet terminal, the gateway sends the wake-up signal to the millimeter wave radar. In the case of receiving the wake-up signal sent by the gateway, the millimeter wave radar will start quickly and enter the working state.

[0099] Step 205: Send the touch position to the cabin domain controller.

[0100] Step 206: Detect the position of the object by the millimeter wave radar.

[0101] ​​Step 207, send the position of the object to the cabin domain controller.

[0102] Step 208, in the case that the cabin domain controller receives the touch position and the position of the object, determine whether to activate the sentinel mode according to the touch position and the position of the object.

[0103] In some embodiments of the present application, the vehicle networking terminal sends the touch position and the touch force of the object to the cabin domain controller.

[0104] In the case that the millimeter wave radar starts and enters the working state, the millimeter wave radar can be used to detect the position of the object around the vehicle and the speed of the object. In the case that the millimeter wave radar obtains the position of the object around the vehicle and the speed of the object, the millimeter wave radar sends the obtained position of the object and the speed of the object to the cabin domain controller.

[0105] In the case that the cabin domain controller receives the touch position sent by the vehicle networking terminal and the position of the object sent by the millimeter wave radar, the cabin domain controller can determine whether to activate the sentinel mode according to the touch position and the position of the object.

[0106] The present application determines the touch position of the object and the vehicle according to the elastic wave signal detected by the elastic wave sensor, and comprehensively judges whether to trigger the sentinel mode in combination with the object position detected by the millimeter wave radar. Compared with the related art which only relies on the detection information of the millimeter wave radar to determine whether to trigger the sentinel mode, this comprehensive judgment method has more dimensional basis, can more accurately determine whether to trigger the sentinel mode, and thus can improve the accuracy of triggering the sentinel mode. In addition, the present application controls to start the millimeter wave radar only after the elastic wave sensor detects the elastic wave signal and determines the touch position and the touch force according to the elastic wave signal. This on-demand starting of the millimeter wave radar avoids unnecessary continuous operation of the millimeter wave radar, thereby reducing the energy consumption of the vehicle.

[0107] Further, in some embodiments of the present application, as shown in Figure 3 after step 201 and before step 202, the following steps can be further included:

[0108] Step 301, in the case that the elastic wave sensor detects the elastic wave signal, perform signal conversion on the elastic wave signal to obtain an electric signal.

[0109] Step 302, send the electric signal to the elastic wave controller.

[0110] In some embodiments of the present application, in the case that the elastic wave sensor detects the elastic wave signal, the elastic wave sensor converts the elastic wave signal into an electric signal, and sends the electric signal to the elastic wave controller, so that the elastic wave controller can further process and analyze the electric signal to obtain the touch position and the touch force between the object and the vehicle.

[0111] The present application converts the elastic wave signal into an electric signal through the elastic wave sensor, and sends the electric signal to the elastic wave controller, so that the elastic wave controller can further process and analyze the electric signal to obtain the touch position and the touch force between the object and the vehicle.

[0112] Further, in some embodiments of the present application, as shown in Figure 4 Step 202 can further include the following steps:

[0113] Step 401, in the case that the elastic wave controller receives the electric signal, filtering the electric signal to obtain a filtered electric signal.

[0114] Step 402, amplifying the filtered electric signal to obtain an amplified electric signal.

[0115] Step 403, extracting the amplitude of the electric signal from the amplified electric signal.

[0116] Step 404, determining the touch force between the object and the vehicle according to the amplitude of the electric signal.

[0117] In some embodiments of the present application, in the case that the elastic wave controller receives the electric signal sent by the elastic wave sensor, in order to remove the noise and interference in the electric signal, the elastic wave controller can filter the electric signal to obtain a filtered electric signal.

[0118] After obtaining the filtered electric signal, in order to enhance the strength of the electric signal and make the electric signal easier to be detected and analyzed, the elastic wave controller can amplify the filtered electric signal to obtain an amplified electric signal.

[0119] The amplitude of the electric signal is related to the strength of the elastic wave signal, and the strength of the elastic wave signal is related to the touch force between the object and the vehicle. Therefore, the size of the touch force between the object and the vehicle can be determined by the amplitude of the electric signal. Therefore, after obtaining the amplified electric signal, the elastic wave controller can extract the amplitude of the electric signal from the amplified electric signal, and take the amplitude of the electric signal as the touch force between the object and the vehicle.

[0120] The application filters and amplifies the electric signal through the elastic wave controller, which helps to more accurately extract the characteristics of the electric signal, such as amplitude, thereby providing a guarantee for accurately determining the touch intensity between the object and the vehicle.

[0121] Further, as shown in Figure 5 , step 202 can further include the following steps:

[0122] Step 501, in the case that the elastic wave controller receives the electric signal, the position of the elastic wave sensor is obtained.

[0123] Step 502, the position of the elastic wave sensor is determined as the touch position between the object and the vehicle.

[0124] In some embodiments of the application, the elastic wave sensor is arranged at different regions on the vehicle.

[0125] In the case that the elastic wave controller receives the electric signal, the elastic wave controller can obtain the position of the elastic wave sensor that sends the electric signal, for example: the elastic wave controller can match the currently received electric signal through the pre-stored elastic wave sensor position information, so as to determine the position of the elastic wave sensor.

[0126] Since the position of the elastic wave sensor is fixed, when the elastic wave sensor detects the elastic wave signal, it can be inferred that the touch event occurs near the elastic wave sensor. Therefore, the position of the elastic wave sensor can be determined as the touch position between the object and the vehicle. For example, if the elastic wave sensor A detects the elastic wave signal, and the elastic wave sensor A is located on the left side of the vehicle, the elastic wave controller will determine the left side of the vehicle as the touch position between the object and the vehicle.

[0127] In the application, the elastic wave controller can match the currently received electric signal through the pre-stored elastic wave sensor position information, so as to determine the position of the elastic wave sensor, and determine the position of the elastic wave sensor as the touch position between the object and the vehicle, which can accurately and quickly obtain the touch position and improve the efficiency of obtaining the touch position.

[0128] Further, as shown in Figure 6 , step 203 can further include the following steps:

[0129] Step 601, determining whether the touch position is a preset key position through the elastic wave controller.

[0130] Step 602, in the case that the touch position is a preset key position, sending the touch position and the touch intensity to the Internet of Vehicles terminal.

[0131] In some embodiments of the present application, the preset critical positions are usually areas on the vehicle that are vulnerable to attack or need special protection, such as door handles, windows, engine covers, etc.

[0132] The elastic wave controller can compare the touch position with the preset critical positions. If the touch position matches one of the preset critical positions, the touch position is determined as a critical position; if the touch position does not match any of the preset critical positions, the touch position is determined as a non-critical position.

[0133] In the case where the touch position is a critical position, the elastic wave controller directly packages the touch position and the touch force into a data packet and sends it to the Internet of Vehicles terminal through the vehicle-mounted network.

[0134] The present application sends the touch position and the touch force to the Internet of Vehicles terminal only when the touch position is a critical position, which can focus on monitoring these vulnerable or special protection areas. When these positions are touched, relevant information can be sent to the Internet of Vehicles terminal in time, so as to make a decision on whether to activate the sentinel mode subsequently.

[0135] Further, in some embodiments of the present application, as shown in FIG. 6B, after step 601, the following steps can also be included: Figure 7

[0136] Step 701, in the case where the touch position is a non-preset critical position, compare the touch force with a preset touch force threshold.

[0137] Step 702, in the case where the touch force is greater than or equal to the preset touch force threshold, send the touch position and the touch force to the Internet of Vehicles terminal.

[0138] In some embodiments of the present application, the preset touch force threshold is usually set according to the safety requirements and design standards of the vehicle, which is used to distinguish between ordinary touch and touch that may cause damage.

[0139] In the case where the touch position is a non-critical position, the elastic wave controller needs to further judge whether the touch force reaches the preset touch force threshold. In the case where the touch force is greater than or equal to the preset touch force threshold, it means that the touch force may cause damage to the vehicle, and the elastic wave controller packages the touch position and the touch force into a data packet and sends it to the Internet of Vehicles terminal through the vehicle-mounted network.

[0140] ​The application compares the touch force with the preset touch force threshold when the touch position is a non-preset key position, which can effectively distinguish between ordinary touch and touch that may cause damage to the vehicle, and in the case where the touch force is greater than or equal to the preset touch force threshold, the touch position and the touch force are sent to the Internet of Vehicles terminal for subsequent decision-making on whether to activate the sentinel mode.

[0141] Further, in some embodiments of the application, as shown in Figure 8 Step 208 can further include the following steps:

[0142] Step 801, determining a position deviation value according to the touch position and the position of the object.

[0143] Step 802, in the case where the position deviation value is greater than the preset deviation threshold, prohibiting the activation of the sentinel mode.

[0144] Step 803, in the case where the position deviation value is less than or equal to the preset deviation threshold, activating the sentinel mode.

[0145] Step 804, controlling the opening of the camera through the Internet of Vehicles terminal, wherein the camera is used to collect images of the vehicle within a preset range.

[0146] In some embodiments of the application, the preset deviation threshold refers to a numerical standard set in the vehicle safety system for judging the reliability of the touch event. The preset deviation threshold is used to compare the difference between the touch position and the position of the object to decide whether to activate the sentinel mode or other safety measures.

[0147] In the case where the cabin domain controller receives the touch position sent by the Internet of Vehicles terminal and the position of the object sent by the millimeter wave radar, the difference between the touch position and the position of the object can be obtained to obtain the position deviation value between the touch position and the position of the object.

[0148] The position deviation value between the touch position and the position of the object is compared with the preset deviation threshold. In the case where the position deviation value is greater than the preset deviation threshold, it is not a malicious touch of the vehicle by human, and the sentinel mode on the vehicle does not need to be activated.

[0149] In the case where the position deviation value is less than or equal to the preset deviation threshold, it is a malicious touch of the vehicle by human, and the sentinel mode on the vehicle is activated through the cabin domain controller. After the activation of the sentinel mode, the camera is controlled to be opened through the Internet of Vehicles terminal, so that the camera is in a working state. In the case where the camera is in the working state, the camera continuously collects images of the environment around the vehicle, so as to further analyze the collected images to judge whether there is abnormal activity (such as theft, damage, etc.), and make corresponding decisions and responses according to the analysis results.

[0150] The application can accurately distinguish between human malicious touch and non-human malicious touch by determining the deviation value of the touch position and the position of the object and comparing it with the preset deviation threshold. In the case where the position deviation value is greater than the preset deviation threshold, the sentinel mode is prohibited to be activated, which can avoid the false triggering of the sentinel mode caused by non-human malicious touch to the vehicle, reduce unnecessary occupation of system resources and unnecessary concerns of the vehicle owner. In the case where the position deviation value is less than or equal to the preset deviation threshold, the sentinel mode is activated, and the camera is called to collect the image around the vehicle after the sentinel mode is activated. Not only can the camera be started as needed to avoid unnecessary continuous operation of the camera, thereby reducing the energy consumption of the vehicle, but also can help to focus on the situation that may truly threaten the safety of the vehicle and conduct more comprehensive detection on the situation that threatens the safety of the vehicle.
