Description

Technical Field

[0001] The embodiments of the present application relate to the field of vehicle safety technology, and in particular to a sentry mode control method, device, electronic device and storage medium. Background Art

[0002] Sentry Mode is a vehicle security feature designed to prevent theft, vandalism, or other potential threats by monitoring the vehicle's surroundings.

[0003] The related sentry mode control method generally obtains radar detection information by continuously detecting the surrounding environment through the millimeter-wave radar on the vehicle, and then determines whether the vehicle meets the wake-up conditions based on the acquired radar detection information. If the vehicle meets the wake-up conditions, the control module enters the wake-up state. In the wake-up state, it is determined whether the vehicle meets the collection conditions based on the radar detection information. When the vehicle meets the collection conditions, the image acquisition device is controlled to collect the surrounding environment of the vehicle, thereby turning on the sentry mode.

[0004] However, the above method mainly relies on a single sensor, namely the millimeter-wave radar. If the millimeter-wave radar fails to work properly due to a malfunction or environmental interference (such as rain, snow, haze, etc.), the sentry mode may not be triggered correctly or may be triggered by mistake. In addition, the continuous operation of the millimeter-wave radar and the image acquisition device will consume more vehicle energy.

[0087] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying 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. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0088] In conjunction with the accompanying drawings, a sentinel mode control method, device, electronic device and storage medium provided in an embodiment of the present application are described in detail through specific embodiments and their application scenarios.

[0089] See also Figure 1 , Figure 1 It is a schematic diagram of a system architecture for implementing a sentinel mode control method provided in an embodiment of the present application.

[0090] The system architecture is set on the vehicle, such as Figure 1 As shown, the system architecture may include an elastic wave sensor, an elastic wave controller, a TBOX (Telematics BOX, a vehicle networking terminal), a millimeter wave radar, a cockpit domain controller, a camera (which may also be a multi-functional camera) and a gateway.

[0091] Figure 2 is a flow chart of the steps of a sentinel mode control method provided in an embodiment of the present application, such as Figure 2 As shown, the method includes:

[0092] Step 201 , when the vehicle turns on the sentry mode, an elastic wave sensor detects an elastic wave signal, wherein the elastic wave signal is a signal generated when an object touches the vehicle.

[0093] Step 202: determining the contact position and contact 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 Internet of Vehicles terminal.

[0095] Step 204: When the Internet of Vehicles terminal receives the touch position and touch force, the millimeter wave radar is controlled to be turned on.

[0096] In some embodiments of the present application, the sentinel mode can be turned on in advance on the vehicle APP (Application). When an object touches the vehicle, an elastic wave signal is generated, and the elastic wave sensor can detect the generated elastic wave signal. Therefore, when the vehicle turns on the sentinel mode, the elastic wave signal can be continuously detected by the elastic wave sensor installed on the vehicle.

[0097] When the elastic wave sensor detects an elastic wave signal, the touch position and touch force between the object and the vehicle can be determined based on the generated elastic wave signal, and the touch position and touch force of the object can be sent to the Internet of Vehicles terminal.

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

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

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

[0101] Step 207, sending the location of the object to the cockpit domain controller;

[0102] Step 208: When the cockpit domain controller receives the touch position and the position of the object, it determines whether to activate the sentry mode according to the touch position and the position of the object.

[0103] In some embodiments of the present application, the Internet of Vehicles terminal sends the touch position and touch force of the object to the cockpit domain controller.

[0104] When the millimeter-wave radar is started and enters the working state, the millimeter-wave radar can detect the position and speed of objects around the vehicle. When the millimeter-wave radar obtains the position and speed of objects around the vehicle, the millimeter-wave radar sends the obtained position and speed of the object to the cockpit domain controller.

[0105] When the cockpit 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 cockpit domain controller can determine whether to activate the sentry mode based on the touch position and the position of the object.

[0106] This application determines the contact position between the object and the vehicle based on the elastic wave signal detected by the elastic wave sensor, and combines it with the position of the object detected by the millimeter-wave radar to comprehensively judge whether to trigger the sentinel mode. Compared with the related technology that 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, which can more accurately determine whether to trigger the sentinel mode, thereby improving the accuracy of the sentinel mode triggering. In addition, this application controls the millimeter-wave radar to start only after the elastic wave sensor detects the elastic wave signal and determines the touch position and touch force based on the elastic wave signal. This method of starting the millimeter-wave radar on demand avoids unnecessary continuous operation of the millimeter-wave radar, thereby reducing vehicle energy consumption.

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

[0108] Step 301: When the elastic wave sensor detects an elastic wave signal, the elastic wave signal is converted into an electrical signal.

[0109] Step 302, sending the electrical signal to the elastic wave controller.

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

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

[0112] Further, in some embodiments of the present application, Figure 4 As shown, step 202 may further include the following steps:

[0113] Step 401: When the elastic wave controller receives an electrical signal, the electrical signal is filtered to obtain a filtered electrical signal.

[0114] Step 402, amplify the filtered electrical signal to obtain an amplified electrical signal.

[0115] Step 403: extracting the amplitude of the electrical signal from the amplified electrical signal.

[0116] Step 404: determine the contact force between the object and the vehicle according to the amplitude of the electrical signal.

[0117] In some embodiments of the present application, when the elastic wave controller receives an electrical signal sent by the elastic wave sensor, in order to remove noise and interference in the electrical signal, the elastic wave controller may filter the electrical signal to obtain a filtered electrical signal.

[0118] After obtaining the filtered electrical signal, in order to enhance the strength of the electrical signal and make the electrical signal easier to detect and analyze, the elastic wave controller can amplify the filtered electrical signal to obtain an amplified electrical 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 contact force between the object and the vehicle. Therefore, the magnitude of the contact 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 use the amplitude of the electric signal as the contact force between the object and the vehicle.

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

[0121] Further, in some embodiments of the present application, Figure 5 As shown, step 202 may further include the following steps:

[0122] Step 501, when the elastic wave controller receives the electrical signal, the position of the elastic wave sensor is obtained.

[0123] Step 502: determine the position of the elastic wave sensor as the contact position between the object and the vehicle.

[0124] In some embodiments of the present application, elastic wave sensors are arranged in different areas on the vehicle.

[0125] When the elastic wave controller receives an electrical signal, the elastic wave controller can obtain the position of the elastic wave sensor that sends the electrical signal. For example, the elastic wave controller can match the currently received electrical signal with pre-stored elastic wave sensor position information 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 an 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 an 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 present application, the elastic wave controller can determine the position of the elastic wave sensor by matching the currently received electrical signal with the pre-stored elastic wave sensor position information, and determine the position of the elastic wave sensor as the touch position between the object and the vehicle, so as to accurately and quickly obtain the touch position and improve the efficiency of obtaining the touch position.

[0128] Further, in some embodiments of the present application, Figure 6 As shown, step 203 may also include the following steps:

[0129] Step 601: determine whether the touched position is a preset key position through an elastic wave controller.

[0130] Step 602: When the touch position is a preset key position, the touch position and the touch force are sent to the Internet of Vehicles terminal.

[0131] In some embodiments of the present application, the preset key locations are usually areas on the vehicle that are vulnerable to attack or require special protection, such as door handles, windows, hoods, etc.

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

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

[0134] The present application sends the touch position and touch force to the Internet of Vehicles terminal only when the touch position is a critical position, so that these vulnerable areas or areas requiring special protection can be monitored in a focused manner. When these positions are touched, relevant information can be sent to the Internet of Vehicles terminal in a timely manner to facilitate subsequent decisions on whether to activate the sentry mode.

[0135] Further, in some embodiments of the present application, Figure 7 As shown, after step 601, the following steps may also be included:

[0136] Step 701: When the touch position is not a preset key position, compare the touch force with a preset touch force threshold.

[0137] Step 702: When the touch force is greater than or equal to a preset touch force threshold, the touch position and touch force are sent to the Internet of Vehicles terminal.

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

[0139] When the touch position is a non-critical position, the elastic wave controller needs to further determine whether the touch force reaches the preset touch force threshold. When 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. The elastic wave controller packages the touch position and touch force into a data packet and sends it to the Internet of Vehicles terminal through the vehicle network.

[0140] When the touch position is not a preset key position, the present application compares the touch force with the preset touch force threshold, which can effectively distinguish between ordinary touches and touches that may cause damage to the vehicle, and when the touch force is greater than or equal to the preset touch force threshold, the touch position and touch force are sent to the Internet of Vehicles terminal to make a subsequent decision on whether to activate the sentry mode.

[0141] Further, in some embodiments of the present application, Figure 8 As shown, step 208 may also 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: When the position deviation value is greater than a preset deviation threshold, activation of the sentinel mode is prohibited.

[0144] Step 803: When the position deviation value is less than or equal to a preset deviation threshold, the sentinel mode is activated.

[0145] Step 804, turning on the camera through the vehicle networking terminal control, wherein the camera is used to collect images of the vehicle within a preset range.

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

[0147] When the cockpit 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 touch position and the position of the object are subtracted to obtain the position deviation value between the touch position and the position of the object.

[0148] The position deviation value between the touched position and the position of the object is compared with a preset deviation threshold. If the position deviation value is greater than the preset deviation threshold, it means that the vehicle is not touched maliciously by a human, and there is no need to activate the sentry mode on the vehicle.

[0149] When the position deviation value is less than or equal to the preset deviation threshold, it indicates that the vehicle is touched maliciously by a human. At this time, the sentry mode on the vehicle is activated through the cockpit domain controller. After the sentry mode is activated, the camera is turned on through the vehicle networking terminal control to put the camera in working state. When the camera is in working state, the camera continuously collects images of the vehicle's surrounding environment in order to further analyze the collected images, determine whether there is any abnormal activity (such as theft, vandalism, etc.), and make corresponding decisions and responses based on the analysis results.

[0150] The present application can accurately distinguish between malicious human touch and non-malicious human touch by determining the deviation value between the touch position and the position of the object and comparing it with the preset deviation threshold. When the position deviation value is greater than the preset deviation threshold, the sentinel mode is prohibited from being activated, which can avoid the false triggering of the sentinel mode due to non-malicious human touches on the vehicle, reduce unnecessary system resource usage and unnecessary worries of the owner. When the position deviation value is less than or equal to the preset deviation threshold, the sentinel mode is activated, and after the sentinel mode is activated, the camera is called to collect images around the vehicle. This can not only start the camera on demand and avoid unnecessary continuous operation of the camera, thereby reducing vehicle energy consumption, but also help focus on situations that may actually threaten vehicle safety, and conduct more comprehensive detection of situations that threaten vehicle safety.
