[0064] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments made by those skilled in the art according to the inspiration of the present embodiments belong to the scope of protection of the present application.

[0065] The terms "first", "second", "third", "fourth" and the like in the description and in the claims of the present application, and above-mentioned drawings, if any, are used to distinguish between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the use of the terms so-termed can be interchanged, where appropriate, to refer to an embodiment of the present application described herein in order that the embodiments of the present application described herein can be carried out in other than the order shown or described herein. Also, the terms "comprising" and "having" and any variations thereof are intended to cover a non-exclusive inclusion, for example, a process, method, system, product or apparatus that comprises a list of steps or units not necessarily limited to those explicitly stated, but can include other not expressly stated or inherent to such processes, methods, products or apparatus.

[0066] With the development of technology and people's concern about vehicle safety, the sentinel mode emerges, which can alarm when the vehicle is damaged, such as scratching and collision.

[0067] In the prior art, for the alarm in the sentinel mode, a camera is usually used to obtain images of the environment around the vehicle in real time, and then a visual model is used to identify the images. When an abnormal target is identified in the image and the moving speed and stay time of the abnormal target meet the conditions, it is determined that the vehicle is damaged and an alarm is given. Since the vehicle needs to run the visual model constantly, the visual model is usually a neural network model or a visual large language model, which requires high computing power and will cause high energy consumption of the vehicle.

[0068] In view of the problems in the prior art, the inventors found, in the process of researching the alarm method in the sentinel mode, that in order to reduce the energy consumption of the vehicle, an elastic wave sensor can be used to detect the collision force, and in order to accurately alarm, a plurality of elastic wave sensors can be used to determine the collision position according to the sensor identifier of the sensor, and to determine whether the vehicle is damaged in combination with the collision force, and then to alarm. Based on the above invention concept, the alarm scheme in the sentinel mode in the present application is designed.

[0069] The controller in the present application can be an electronic control unit (ECU), a vehicle control unit (VCU), a vehicle terminal, etc. in the vehicle, and the embodiments of the present application do not limit the controller, which can be determined according to the actual situation.

[0070] The application scenario of the alarm method in the sentinel mode provided by the present application is described below.

[0071] For example, in this application scenario, the user drives the vehicle into the garage, parks the vehicle in the parking space, and then the vehicle is powered off and enters the sentinel mode.

[0072] After the vehicle enters the sentinel mode, a controller in the vehicle acquires the elastic wave signals and sensor identifiers transmitted by the plurality of elastic wave sensors in real time.

[0073] After the collision intensity and the collision position corresponding to each elastic wave sensor are determined according to the elastic wave signals and the sensor identifiers transmitted by each elastic wave sensor, if the collision intensity and the collision position corresponding to the plurality of elastic wave sensors satisfy a preset alarm condition, an alarm is performed.

[0074] If the collision intensity and the collision position corresponding to the plurality of elastic wave sensors satisfy a first preset alarm condition, that is, there is an elastic wave sensor with a collision intensity greater than a first preset intensity and a collision position in the vehicle window glass region among the plurality of elastic wave sensors, it indicates that the vehicle window glass is damaged, and the damage needs to be warned to the damage person by using the light and the horn, so as to avoid the loss of the property in the vehicle, and the user also needs to be reminded that the vehicle is damaged, therefore, the controller plays the alarm audio, controls the vehicle light to flash, and sends the alarm information to the terminal device of the user.

[0075] It should be noted that the above scenario is only an example of an application scenario provided by the embodiments of the present application, and the actual forms of various devices included in the scenario are not limited, and the interaction mode between the devices is not limited, and in the specific application of the scheme, the actual needs can be set.

[0076] In the following, the technical scheme of the present application is described in detail through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in detail in some embodiments.

[0077] FIG. 1a is a flowchart of an alarm method in a sentinel mode according to an embodiment of the present application. The embodiments of the present application describe the alarm in the sentinel mode according to the elastic wave signals and the sensor identifiers transmitted by the elastic wave sensors. The method in the embodiment can be realized by software, hardware, or a combination of software and hardware. As shown in FIG. 1a, the alarm method in the sentinel mode specifically includes the following steps:

[0078] S101: After the vehicle enters the sentinel mode, the elastic wave signals and the sensor identifiers transmitted by the plurality of elastic wave sensors are acquired in real time.

[0079] In this step, after the vehicle enters the sentinel mode, in order to improve the safety of the vehicle, the elastic wave signals and the sensor identifiers transmitted by the plurality of elastic wave sensors need to be acquired in real time.

[0080] It should be noted that, in order to improve the detection accuracy of the elastic wave sensor, the elastic wave sensor needs to be installed in the planar area of the vehicle body, and the installation areas of the plurality of elastic wave sensors include a vehicle window glass area and a non-vehicle window glass area. The vehicle window glass area includes all vehicle window glasses, and the non-vehicle window glass area includes all vehicle door areas, vehicle body bumper areas, front hood areas, rear hood areas, roof areas, and front windshield areas. At least one elastic wave sensor is installed on at least one area of all vehicle door areas, vehicle body bumper areas, front hood areas, rear hood areas, roof areas, and front windshield areas.

[0081] For example, one elastic wave sensor is installed on each of the four vehicle window glasses, one elastic wave sensor is installed on each of the four vehicle door areas, and one elastic wave sensor is installed on each of the four vehicle body bumper areas.

[0082] The number of sensors installed in the vehicle window glass area and the non-vehicle window glass area and the areas included in the non-vehicle window glass area are not limited in the embodiments of the present application, and can be determined according to actual conditions.

[0083] It should be noted that the vehicle can enter the sentry mode in the following ways: the vehicle is powered off, the vehicle stops for a preset stop time, the vehicle enters the sentry mode in response to a user operation, the distance between the vehicle key and the vehicle is greater than a preset distance, and the like. The preset stop time can be 2 minutes, 3 minutes, 5 minutes, or the like, and the preset distance can be 10 meters, 20 meters, 30 meters, or the like. The embodiments of the present application do not limit the way the vehicle enters the sentry mode, the preset time, and the preset distance, and can be determined according to actual conditions.

[0084] S102: According to the elastic wave signal transmitted by each elastic wave sensor and the sensor identifier, the corresponding collision force and collision position of each elastic wave sensor are determined.

[0085] In this step, after the controller obtains the elastic wave signal and the sensor identifier transmitted by the plurality of elastic wave sensors, according to the elastic wave signal transmitted by each elastic wave sensor and the sensor identifier, the corresponding collision force and collision position of each elastic wave sensor are determined.

[0086] Specifically, for each elastic wave sensor, according to the frequency of the elastic wave signal transmitted by the elastic wave sensor and the preset frequency-force correspondence relationship, the corresponding collision force of the elastic wave sensor is determined.

[0087] It should be noted that, for the preset frequency and the corresponding relationship of the strength, the greater the frequency, the greater the strength. For example, the frequency is 20 Hz, and the corresponding strength is 10 N; the frequency is 180 Hz, and the corresponding strength is 200 N; the frequency is 500 Hz, and the corresponding strength is 600 N. The preset frequency and the corresponding relationship of the strength are not limited in the embodiment of the application, and can be determined according to actual conditions.

[0088] For each elastic wave sensor, according to the sensor identifier transmitted by the elastic wave sensor and the preset sensor identifier and position corresponding relationship, the corresponding collision position of the elastic wave sensor is determined.

[0089] The collision position includes a vehicle window glass region and a non-vehicle window glass region, and the vehicle window glass region and the non-vehicle window glass region both include at least one installation position. The preset sensor identifier and position corresponding relationship is the corresponding relationship between the sensor identifier and the installation position. Therefore, the installation position corresponding to the sensor identifier of the elastic wave sensor can be determined, and the collision position is further determined.

[0090] For example, the vehicle window glass region includes installation positions A, B, C and D, and the non-vehicle window glass region includes installation positions E, F, G, H, I, J, K and L. The installation position corresponding to the sensor identifier of the elastic wave sensor is B, so the corresponding collision position of the elastic wave sensor is determined as the vehicle window glass region.

[0091] S103: If the corresponding collision strength and collision position of the plurality of elastic wave sensors meet the preset alarm condition, an alarm is performed.

[0092] In this step, after the controller determines the corresponding collision strength and collision position of each elastic wave sensor, if the corresponding collision strength and collision position of the plurality of elastic wave sensors meet the preset alarm condition, an alarm is performed.

[0093] There are a plurality of preset alarm conditions, and the preset alarm conditions met by the collision strength and the collision position are different, and the alarm modes are different.

[0094] It should be noted that, since the controller will record the video of the environment around the vehicle body through the camera device, when the alarm is performed, the video of the preset time length before the current time will be saved, and the video of the preset time length after the current time will be recorded and saved. The preset time length can be 30 seconds, 1 minute, 2 minutes, etc. The preset time length is not limited in the embodiment of the application, and can be determined according to actual conditions.

[0095] For example, FIG. 1b is a schematic diagram of the architecture of the vehicle provided by the application, as shown in FIG. 1b, the vehicle includes a controller, a plurality of elastic wave sensors, a plurality of camera devices, a loudspeaker and a vehicle lamp. The controller is connected with each elastic wave sensor, each camera device, the loudspeaker and the vehicle lamp respectively.

[0096] The controller acquires the elastic wave signals and sensor identifiers transmitted by the plurality of elastic wave sensors, determines the collision intensity and the collision position, and if it is determined that the collision intensity and the collision position corresponding to the plurality of elastic wave sensors satisfy a preset alarm condition, an alarm is performed. The alarm can be performed by playing alarm audio through a loudspeaker, and / or controlling the vehicle lights to flash, and sending alarm information to the user's terminal device. The video of a preset time period before and after the current time can also be saved through a camera device.

[0097] The alarm method in the sentry mode provided in this embodiment determines the collision intensity and the collision position corresponding to each elastic wave sensor according to the elastic wave signals and sensor identifiers transmitted by the plurality of elastic wave sensors in real time after the vehicle enters the sentry mode. Then, when the collision intensity and the collision position corresponding to the plurality of elastic wave sensors satisfy a preset alarm condition, an alarm is performed. This scheme performs the alarm according to the collision intensity and the collision position corresponding to the elastic wave sensors, without running a visual model, thereby reducing the energy loss of the vehicle. In addition, the alarm in the sentry mode is realized through a visual model, which is prone to poor detection accuracy in poor external lighting, leading to false alarms. In this scheme, the process of determining the elastic wave signals and sensor identifiers by the elastic wave sensors is irrelevant to the lighting, so the occurrence of false alarms can be reduced.

[0098] On the basis of the above-mentioned embodiments, the alarm method in the sentry mode embodiment two is used to describe the case where the controller determines that the collision intensity and the collision position corresponding to the plurality of elastic wave sensors satisfy a preset alarm condition, and an alarm is performed.

[0099] If the collision intensity and the collision position corresponding to the plurality of elastic wave sensors satisfy a first preset alarm condition, an alarm is performed according to a first alarm mode.

[0100] The first preset alarm condition is that there is an elastic wave sensor in the plurality of elastic wave sensors whose collision intensity is greater than a first preset intensity and whose collision position is a vehicle window glass region.

[0101] It should be noted that the first preset intensity is the intensity at which the vehicle window is damaged, which can be 150 N, 180 N, 230 N, etc. The first preset intensity is not limited in the embodiments of the present application and can be determined according to actual conditions.

[0102] The first alarm mode is to control a loudspeaker to play alarm audio, control vehicle lights to flash, and send alarm information to a user's terminal device.

[0103] The plurality of elastic wave sensors meet the first preset alarm condition, indicating that the vehicle window is damaged. In order to prevent the loss of property in the vehicle, the damage to the vehicle needs to be maximally warned, so light and horn warning are used, and the user needs to be reminded that the vehicle is damaged, so the loudspeaker plays alarm audio, the vehicle light flashes, and alarm information is sent to the terminal device of the user.

[0104] If the collision intensity and the collision position corresponding to the plurality of elastic wave sensors meet the second preset alarm condition, the second alarm mode is used for alarm.

[0105] The second preset alarm condition is that there is no elastic wave sensor with a collision intensity greater than the first preset intensity and a collision position in the vehicle window glass area in the plurality of elastic wave sensors, and there is an elastic wave sensor with a collision intensity greater than the second preset intensity and a collision position in the non-vehicle window glass area in the plurality of elastic wave sensors.

[0106] It should be noted that the second preset intensity is greater than the first preset intensity, and the second preset intensity is the intensity of the impact on the vehicle body, which can be 350N, 500N, 600N, etc. The second preset intensity is not limited in the embodiment of the application and can be determined according to the actual situation.

[0107] The second alarm mode is to send alarm information to the terminal device of the user.

[0108] If the collision intensity and the collision position corresponding to the plurality of elastic wave sensors meet the second preset alarm condition, it indicates that the vehicle window is not damaged and the vehicle body is impacted. At this time, the impactor does not need to be warned, and in order to save energy consumption, only alarm information is sent to the terminal device of the user.

[0109] If the collision intensity and the collision position corresponding to the plurality of elastic wave sensors meet the third preset alarm condition, the third alarm mode is used for alarm.

[0110] The third preset alarm condition is that there is no elastic wave sensor with a collision intensity greater than the first preset intensity and a collision position in the vehicle window glass area in the plurality of elastic wave sensors, and there is an elastic wave sensor with a collision intensity less than or equal to the second preset intensity and greater than the third preset intensity and a collision position in the non-vehicle window glass area in the plurality of elastic wave sensors.

[0111] It should be noted that the first preset intensity is greater than the third preset intensity, and the third preset intensity is the intensity of the scratch on the vehicle body, which can be 10N, 15N, 20N, etc. The third preset intensity is not limited in the embodiment of the application and can be determined according to the actual situation.

[0112] The third alarm mode is to send alarm information to the terminal device of the user, and to control the loudspeaker to play alarm audio or to control the vehicle light to flash.

[0113] If the collision intensity and the collision position corresponding to the plurality of elastic wave sensors satisfy the third preset alarm condition, it indicates that the vehicle window is not damaged, and the vehicle body is scratched, at this time, only a small degree of warning to the damaged person is needed, and in order to save energy consumption, the alarm audio is played by controlling the loudspeaker or the vehicle light is controlled to flash. It is also necessary to send alarm information to the terminal device of the user to prompt the user that the vehicle is damaged.

[0114] For example, FIG. 2 is an example of an alarm process provided by the present application. The controller can alarm through the alarm process in FIG. 2. As shown in FIG. 2, the alarm process includes:

[0115] S201: Determine whether the collision intensity and the collision position corresponding to the plurality of elastic wave sensors satisfy the first preset alarm condition. If the collision intensity and the collision position corresponding to the plurality of elastic wave sensors satisfy the first preset alarm condition, execute step S202; if the collision intensity and the collision position corresponding to the plurality of elastic wave sensors do not satisfy the first preset alarm condition, execute step S203.

[0116] In this step, after the controller determines the collision intensity and the collision position corresponding to each elastic wave sensor, it first determines whether the collision intensity and the collision position corresponding to the plurality of elastic wave sensors satisfy the first preset alarm condition, to determine whether the vehicle window glass is damaged.

[0117] S202: Alarm according to the first alarm mode.

[0118] In this step, if the controller determines that the collision intensity and the collision position corresponding to the plurality of elastic wave sensors satisfy the first preset alarm condition, it indicates that the vehicle window glass is damaged, and alarms according to the first alarm mode.

[0119] S203: Determine whether the collision intensity and the collision position corresponding to the plurality of elastic wave sensors satisfy the second preset alarm condition. If the collision intensity and the collision position corresponding to the plurality of elastic wave sensors satisfy the second preset alarm condition, execute step S204; if the collision intensity and the collision position corresponding to the plurality of elastic wave sensors do not satisfy the second preset alarm condition, execute step S205.

[0120] In this step, if the controller determines that the collision intensity and the collision position corresponding to the plurality of elastic wave sensors do not satisfy the first preset alarm condition, it indicates that the vehicle window glass is not damaged, and then in order to determine whether the vehicle body is hit, it is necessary to determine whether the collision intensity and the collision position corresponding to the plurality of elastic wave sensors satisfy the second preset alarm condition.

[0121] S204: Alarm according to the second alarm mode.

[0122] In this step, the controller determines that the vehicle body is impacted if the collision intensity and the collision position corresponding to the plurality of elastic wave sensors meet the second preset alarm condition, and alarms according to the second alarm mode.

[0123] S205: Determine whether the collision intensity and the collision position corresponding to the plurality of elastic wave sensors meet a third preset alarm condition; if the collision intensity and the collision position corresponding to the plurality of elastic wave sensors meet the third preset alarm condition, execute step S206; if the collision intensity and the collision position corresponding to the plurality of elastic wave sensors do not meet the third preset alarm condition, execute step S207.

[0124] In this step, the controller determines that the vehicle body is not impacted if the collision intensity and the collision position corresponding to the plurality of elastic wave sensors do not meet the second preset alarm condition, and needs to determine whether the vehicle body is scratched by determining whether the collision intensity and the collision position corresponding to the plurality of elastic wave sensors meet the third preset alarm condition.

[0125] S206: Alarm according to a third alarm mode.

[0126] In this step, the controller determines that the vehicle body is scratched if the collision intensity and the collision position corresponding to the plurality of elastic wave sensors meet the third preset alarm condition, and alarms according to the third alarm mode.

[0127] S207: Do not alarm.

[0128] In this step, the controller determines that the vehicle body is not scratched, the vehicle body is not impacted, and the vehicle window glass is not damaged if the collision intensity and the collision position corresponding to the plurality of elastic wave sensors do not meet the third preset alarm condition, and does not alarm.

[0129] The alarm method in the sentry mode provided in this embodiment can alarm according to different alarm modes by meeting different preset alarm conditions according to the collision intensity and the collision position corresponding to the plurality of elastic wave sensors, and can achieve accurate alarm and reduce energy consumption.

[0130] FIG. 3 is a flowchart of an alarm method in a sentry mode according to an embodiment of the present application. The embodiment of the present application describes the case that the controller saves the video of the surroundings of the vehicle when the vehicle is impacted during the driving of the vehicle. As shown in FIG. 3, the alarm method in the sentry mode specifically includes the following steps:

[0131] S301: Real-time acquire the elastic wave signals transmitted by the plurality of elastic wave sensors during the driving of the vehicle.

[0132] In this step, in order to detect whether the vehicle is collided during driving, the elastic wave signals transmitted by the plurality of elastic wave sensors need to be acquired in real time.

[0133] S302: Determine the collision intensity corresponding to each elastic wave sensor according to the elastic wave signal transmitted by each elastic wave sensor.

[0134] In this step, after the controller acquires the elastic wave signal, the collision intensity corresponding to each elastic wave sensor is determined according to the elastic wave signal transmitted by each elastic wave sensor.

[0135] It should be noted that this step is similar to the process of determining the collision intensity in S102 of Embodiment I, which will not be described here.

[0136] S303: If the collision intensity corresponding to at least one elastic wave sensor is greater than the fourth preset intensity, save the video of the surrounding environment of the vehicle within a preset time period before and after the current time.

[0137] In this step, after the controller determines the collision intensity corresponding to each elastic wave sensor, if the collision intensity corresponding to at least one elastic wave sensor is greater than the fourth preset intensity, it means that the vehicle is collided, and the video of the surrounding environment of the vehicle within a preset time period before and after the current time is saved.
