[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on March 30, 2024, with application number 202410396147.0 and application name “Environmental Detection Methods and Related Devices,” the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of automobile technology, and in particular to an environment detection method and related devices. Background Art

[0003] When a vehicle is parked, scratches, collisions, and other incidents can cause damage. In unmonitored areas, it can be difficult for the owner to obtain evidence, or even impossible to provide. To ensure parking safety and protect the rights of vehicle owners, a system that detects a risky situation can alert the owner and save a video of the surrounding area. However, existing designs for this feature consume high power, leading to a pressing challenge: designing a low-power, yet highly accurate detection solution. Summary of the Invention

[0004] The embodiments of the present application provide an environment detection method and related devices, which can reduce power consumption when the security guard function is turned on.

[0005] In the first aspect, an embodiment of the present application provides an environment detection method, which can be performed by a detection unit. The detection unit can be a device, or a chip (system) or circuit for a device, and the present application does not limit this. In this method, the detection unit obtains first environment data and performs environment detection based on the first environment data when the vehicle is in a parking state. When a first trigger event is detected, the detection unit can send a first wake-up signal and second environment data to a computing unit. Wherein, the second environment data includes the first environment data and / or a data processing result obtained based on the first environment data. In an embodiment of the present application, when the vehicle is in a parking state, the detection unit is in a powered state (or referred to as being in a working state), and before receiving the first wake-up signal, the computing unit is in a dormant state. That is to say, by normally opening the detection unit with lower power consumption and waking up the computing unit with higher power consumption through the detection unit for accurate detection, the detection accuracy of the environmental safety detection function is guaranteed, and it is also beneficial to save power consumption.

[0006] In a possible implementation, the power consumption of the detection unit is lower than the power consumption of the calculation unit when it is awakened and working.

[0007] In a possible implementation, the first environmental data includes a vibration signal from an acceleration sensor;

[0008] The method further comprises:

[0009] The detection unit determines that the first trigger event is detected when the vibration signal exceeds a first vibration threshold.

[0010] In this implementation, when the detection unit preliminarily identifies a vibration event that may cause danger, it can wake up the computing unit to perform more accurate detection, which has strong operability.

[0011] In a possible implementation, the first environmental data includes perception data from an environmental perception sensor;

[0012] The method further comprises:

[0013] The detection unit determines whether there is a moving object around the vehicle based on the perception data;

[0014] The detection unit determines that a first trigger event is detected when it is determined that a moving object exists around the vehicle.

[0015] In this implementation mode, when the detection unit detects that an object is approaching the area around the vehicle, it can wake up the computing unit to perform more accurate detection, which has strong operability.

[0016] In a possible implementation, the detection unit includes a perception data processing module and a vibration signal processing module; the first environmental data includes a vibration signal from an acceleration sensor and perception data from an environmental perception sensor;

[0019] The perception data processing module determines whether there is a moving object around the vehicle based on the perception data;

[0020] The perception data processing module determines that a first trigger event is detected when it is determined that there is a moving object around the vehicle;

[0021] Before receiving the second wake-up signal, the perception data processing module is in a dormant state.

In this method, the computing unit receives a first wake-up signal and second environment data from the detection unit. Therefore, it can determine whether to generate an alarm message based on the second environment data after waking up. It should be understood that the above-mentioned second environment data includes the first environment data and / or the data processing result obtained according to the first environment data.

[0024] In an embodiment of the present application, a detection unit with lower power consumption is kept open, and a computing unit with higher power consumption is awakened by the detection unit to perform precise detection.

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character “ / ” generally indicates that the related objects before and after are in an “or” relationship.

[0201] Furthermore, unless otherwise indicated, ordinal numbers such as "first" and "second" in the embodiments of this application are used to distinguish between multiple objects and are not used to define the order, timing, priority, or importance of multiple objects. For example, the first message and the second message are only used to distinguish different message types and do not indicate differences in structure, importance, etc. between the two messages.

[0202] First, some terms in this application are explained to facilitate understanding by those skilled in the art.

[0203] 1. Security Guard Function

[0204] The safety guard function refers to the function of detecting the safety status of the vehicle through sensors on the vehicle while the vehicle is parked. When it is determined that the vehicle is at risk of damage or intrusion, it notifies the owner and records relevant environmental information.

[0205] 2. Sensors

[0206] The sensors involved in the embodiments of the present application include acceleration sensors (also known as vibration sensors, shock sensors, etc.) and environmental perception sensors. The environmental perception sensors may include vision sensors and / or radar sensors, etc., without limitation. Exemplarily, vision sensors include fisheye, eagle eye, monocular, binocular, four-way cameras, etc., without limitation here. Radar sensors may include radar (radio detection and ranging, Radar), laser radar (light detection and ranging, LiDAR), millimeter wave radar, ultrasonic radar, etc., without limitation here.

[0207] In real life, when the driver parks and leaves the car, the vehicle is often scratched or collided. In response to the need for car safety monitoring after the driver leaves the car, the safety guard function has been introduced. Under the safety guard function, the safety of the vehicle is detected by sensors on the vehicle, and an early warning is issued and the sensed data is recorded after a predefined event occurs, which can help car owners maintain their rights and reduce their losses. In related technologies, the safety guard function is usually achieved with the help of sensors and analysis capabilities of intelligent driving (referred to as intelligent driving domain). Due to the reuse of the algorithm module of intelligent driving, it is necessary to run the algorithm module of intelligent driving when running the safety guard function, resulting in high computing power consumption and large power consumption. Therefore, how to design a solution with low power consumption and high detection accuracy has become an urgent problem to be solved.

[0208] Based on this, this application proposes an environmental detection method that can reduce vehicle power consumption and help improve user experience.

[0209] For example, please refer to Figure 1, which is a schematic diagram of a system architecture applicable to an embodiment of the present application. As shown in Figure 1, the system includes a mobile data center (MDC) and a cockpit domain controller (CDC). The MDC includes four cameras, an ultrasonic radar, an accelerometer, a microcontroller unit (MCU), and a system on chip (SOC), etc. The SOC is connected to the four cameras, the accelerometer and the ultrasonic radar are connected to the MCU, and the MCU is connected to the SOC. By deploying lightweight vibration detection and radar detection on the MCU, high-power components such as the SOC and CDC do not need to be constantly on during the operation of the safety guard function. Specifically, the MCU can be constantly on and receive vibration information collected by the accelerometer for vibration detection or receive radar signals collected by the radar for radar detection. If the MCU identifies vibrations that may pose a threat to the vehicle or objects close to the vehicle, it wakes up the SOC for further, more accurate detection. After waking up, the SOC receives the video data streams collected by the four cameras, as well as the vibration and radar detection information provided by the MCU. After processing by algorithms such as motion frame detection, radar detection, vibration detection, and human-vehicle artificial intelligence (AI) detection, it finally determines whether a dangerous event has occurred. If it is determined that an event that harms the vehicle has occurred, an alarm message is sent to the CDC. In addition, the CDC can write the video corresponding to the dangerous event to the disk. It should be understood that the MCU is deployed with lightweight vibration detection and radar detection algorithms, powered by a small battery (for example, 20AH).

[0210] As another example, please refer to Figure 2, which is another system architecture diagram applicable to the embodiment of the present application. As shown in Figure 2, the system includes four cameras, ultrasonic radar, acceleration sensor, automatic parking assist (APA), MCU and CDC. The APA is connected to the four cameras and ultrasonic radar, the acceleration sensor is connected to the MCU, and the APA and MCU are both connected to the CDC. By deploying lightweight vibration detection on the MCU, and deploying lightweight visual detection and radar detection on the APA, high-power components such as the CDC do not need to be constantly on during the operation of the safety guard function. Specifically, the MCU is constantly on to obtain and detect the vibration signal collected by the acceleration sensor. If a vibration that may pose a threat to the vehicle is detected, the CDC is awakened for further detection with higher accuracy. At the same time, the APA can also use the perception data collected by the ultrasonic radar and the four cameras for detection. When an approaching object is detected around the vehicle, the CDC can also be awakened for further detection with higher accuracy. After waking up, the CDC can perform motion frame detection, radar detection, vibration detection, and human-vehicle AI detection on data from the MCU and APA based on the visual system. The fusion processing system then makes a comprehensive judgment on the visual system's detection results. If it determines that an event has occurred that poses a threat to the vehicle, it triggers a highlighted alarm on the display and pushes it remotely to the user's mobile phone. Ultimately, the effective video storage system writes it to the disk. It should be understood that both the APA and the MCU can operate independently. The APA deploys lightweight algorithms such as visual detection and radar detection, while the MCU deploys lightweight algorithms such as vibration detection, powered by a small battery (e.g., 20AH).

[0211] It should be noted that the "parking" mentioned in this application means that the vehicle is stopped and the parking gear is engaged. Optionally, parking can sometimes also be referred to as parking, which is not limited in this application. In addition, being in a powered state can also be understood as being in an operating state.

[0212] The following is a detailed introduction to the environmental detection method and related devices provided by this application:

[0213] Please refer to Figure 3, which is a flow chart of the environment detection method provided by an embodiment of the present application. As shown in Figure 3, the environment detection method includes the following steps S301 to S303. The execution subject of the method shown in Figure 3 can be a vehicle, or the execution subject of the method shown in Figure 3 can also be a chip or vehicle-mounted component in which the detection software is deployed in the vehicle. For example, the detection software can be deployed in the vehicle's CDC, MDC, APA, MCU and other vehicle-mounted components (or chips), and this application does not limit this. For the convenience of description, Figure 3 mainly uses the vehicle-mounted component in which the detection software is deployed in the vehicle as an example of the execution subject of the method. Specifically, the vehicle component can be a detection unit, a computing unit or a control unit. It should be noted that Figure 3 is a schematic flow chart of an embodiment of the method of the present application, showing the detailed communication steps or operations of the method, but these steps or operations are only examples. The embodiment of the present application can also perform other operations or variations of the various operations in Figure 3. In addition, the various steps in Figure 3 can be performed in a different order from that presented in Figure 3, and it is possible that not all operations in Figure 3 need to be performed. Among them:

[0214] S301 : When a vehicle is in a parking state, a detection unit obtains first environmental data and performs environmental detection according to the first environmental data.

[0215] In some feasible implementations, when the vehicle is in a parked state, sensors deployed on the vehicle continuously collect first environmental data around the vehicle and send the collected first environmental data to the detection unit. Accordingly, after the detection unit receives the first environmental data from the sensor, it can perform environmental detection based on the acquired first environmental data. Specifically, when the vehicle is in a parked state, the detection unit is in a powered state, and the computing unit is in a dormant state before receiving the first wake-up signal. In addition, the power consumption of the detection unit is lower than the power consumption of the computing unit when it is working after being awakened.

[0216] In one possible implementation (I), if the system architecture shown in FIG1 is used, the detection unit can specifically be an MCU, and the sensors connected to the MCU can include an accelerometer and a radar sensor, that is, the accelerometer and the radar sensor have a communication connection with the MCU. The first environmental data collected by the accelerometer is a vibration signal, and the first environmental data collected by the radar sensor is a radar signal. The MCU can determine whether the vehicle is generating abnormal vibrations based on the vibration signal, or can determine whether there are moving objects around the vehicle based on the radar signal. Specifically, if the vibration intensity indicated by the vibration signal is not less than a first vibration threshold, it can be determined that the vehicle is generating abnormal vibrations; if the vibration intensity indicated by the vibration signal is less than the first vibration threshold, it can be determined that the vehicle is not generating abnormal vibrations. Radar detection can be used to determine whether an object is approaching the vehicle. For example, if the distance between the moving object and the vehicle is less than or equal to a certain distance threshold (hereinafter referred to as the first distance threshold for ease of distinction) determined based on the radar signal, it can be determined that there is a moving object around the vehicle; if the distance between the moving object and the vehicle is greater than the first distance threshold, it can be determined that there are no moving objects around the vehicle. It should be understood that the branch to which the "equal to" situation involved in the embodiments of the present application belongs can be determined according to actual circumstances and is not limited.

[0217] Generally speaking, if the MCU detects abnormal vibration and / or detects the presence of a moving object approaching the vehicle, it is considered that a first trigger event has been detected. For example, the moving object may refer to a moving person, a motor vehicle, a non-motor vehicle, etc., without limitation.

[0218] In one possible implementation (two), if the system architecture shown in Figure 2 is adopted, the detection unit may specifically include an MCU and / or an APA, the sensor connected to the MCU may be an acceleration sensor, and the sensor connected to the APA may include an environmental perception sensor, where the environmental perception sensor may specifically be a visual sensor and / or a radar sensor. For the convenience of description, the following text uses the environmental perception sensor including a visual sensor and a radar sensor as an example for schematic illustration. The first environmental data collected by the acceleration sensor is a vibration signal, and the first environmental data collected by the environmental perception sensor is perception data. For example, the video image data collected by the visual sensor and the radar signal collected by the radar sensor can be understood as perception data. The MCU can determine whether the vehicle has abnormal vibrations based on the vibration signal, and the APA can determine whether there are moving objects around the vehicle based on the radar signal or the video image data. Specifically, the APA can process the radar signal or the video image data according to the motion detection algorithm to determine whether there are moving objects around the vehicle.

[0219] S302: When the detection unit detects a first trigger event, the detection unit sends a first wake-up signal and second environment data to the computing unit. Correspondingly, the computing unit receives the first wake-up signal and second environment data from the detection unit.

[0220] In some feasible implementations, the detection unit can determine whether a first trigger event exists by performing environmental detection on the first environmental data. Generally speaking, when it is determined that the vehicle generates abnormal vibrations and / or there are moving objects around the vehicle, it can be determined that the first trigger event has been detected. Therefore, the detection unit wakes up the computing unit and sends the second environmental data to the computing unit, and the second environmental data includes the first environmental data and / or the data processing result obtained based on the first environmental data. It should be understood that the first wake-up signal and the second environmental data can be sent to the computing unit together, or they can be sent to the computing unit separately, which is not limited in this application. Accordingly, for the computing unit, the first wake-up signal and the second environmental data can be received at one time, or they can be received separately, which is not limited in this application. In addition, for the computing device, the computing device usually needs to be woken up first and then receive the second environmental data.

[0221] Exemplarily, the first environmental data included in the second environmental data may refer to perception data (such as video image data, or one or more of radar signals, etc.) and vibration signals, etc., and the data processing result includes the suspected area where the moving object is located. The suspected area where the moving object is located can be determined based on the perception data. For example, the detection unit can process the video image data based on the motion frame detection algorithm to determine the suspected area where the moving object is located; for another example, the detection unit can process the radar signal based on the radar detection algorithm to determine the suspected area where the moving object is located. For another example, the detection unit can also determine the union area of ​​the suspected area determined based on the video image data and the suspected area determined based on the radar signal as the suspected area where the moving object is located, which is not limited in this application.

[0222] In one possible implementation (1), if the system architecture shown in Figure 1 is used, the computing unit may be the SOC. That is, when the MCU detects abnormal vibration of the vehicle or the presence of a moving object around the vehicle, the MCU may wake up the SOC and send second environmental data to the SOC. For example, the second environmental data may include a vibration signal.

[0223] In one possible implementation (two), if the system architecture shown in Figure 2 is used, the computing unit may be a CDC. That is, when the MCU detects abnormal vibration of the vehicle or the APA detects the presence of a moving object around the vehicle, the MCU or APA may wake up the CDC and send second environmental data to the CDC. For example, the second environmental data may include video image data, vibration signals, and the suspected location of the moving object.

[0224] S303: The calculation unit determines whether to generate alarm information based on the second environment data.

[0225] As described above, the second environmental data includes the first environmental data and the data processing results obtained based on the first environmental data, wherein the first environmental data includes perception data (such as video image data, radar signals) and vibration signals, and the data processing results include the suspected area where the moving object is located. In some feasible embodiments, the computing unit can process the video image data based on the AI ​​detection algorithm to determine whether there is an object of interest. In the case that the computing unit does not detect any object of interest, the computing unit can re-enter the sleep state; in the case that the computing unit detects at least one object of interest, the computing unit can further determine the target moving object based on the area where the at least one object of interest is located and the suspected area where the moving object is located. Specifically, when the degree of overlap between the area where a certain object of interest is located and the suspected area where the moving object is located is greater than or equal to a preset overlap threshold, the object of interest can be considered to be the target moving object. The object of interest can refer to a person, a motor vehicle, a non-motor vehicle, etc., and this application does not impose any restrictions on this.

[0226] For example, please refer to Figure 4, which is a schematic diagram of the target moving object provided in an embodiment of the present application. As shown in Figure 4, based on the AI ​​detection algorithm, the video image data is processed to detect four objects of interest, namely object of interest 1, object of interest 2, object of interest 3, and object of interest 4. Among them, since the overlap between the areas where objects of interest 1, 2, and 3 are located and the suspected area where the moving object is located is less than the preset overlap threshold, and the overlap between the area where object of interest 4 is located and the suspected area where the moving object is located is greater than the preset overlap threshold, object of interest 4 is the target moving object.

[0227] It is understandable that the computing unit can generate an alarm message when the distance between the target mobile object and the vehicle is less than or equal to a certain distance threshold (hereinafter referred to as the second distance threshold for ease of distinction) and / or when the vibration intensity of the vehicle indicated by the vibration signal is greater than or equal to the second vibration threshold. If the distance between the target mobile object and the vehicle is greater than the second distance threshold and the vibration intensity of the vehicle is less than the second vibration threshold, the computing unit re-enters the dormant state. Generally speaking, the first distance threshold is greater than the second distance threshold, and the first vibration threshold is less than the second vibration threshold.

[0228] Optionally, the warning information may include a target warning level, which is one of a plurality of warning levels, and the plurality of warning levels are used to indicate the severity of the warning information. For example, the plurality of warning levels include a first warning level and a second warning level, wherein the first warning level is lower than the second warning level. Specifically, when the distance between the target moving object and the vehicle is less than or equal to the second distance threshold, or when the distance between the target moving object and the vehicle is less than or equal to the second distance threshold and the vibration intensity of the vehicle is less than the second vibration threshold, the target warning level is the first warning level; when the vibration intensity of the vehicle is greater than or equal to the vibration threshold, or when the distance between the target moving object and the vehicle is less than or equal to the second distance threshold and the vibration intensity of the vehicle is greater than or equal to the second vibration threshold, the target warning level is the second warning level.

[0229] In one possible implementation (I), if the system architecture shown in Figure 1 is used, the computing unit may be a system-on-chip (SOC). That is, when the MCU detects abnormal vehicle vibration and / or the presence of moving objects around the vehicle, the MCU may wake up the SOC. After waking up, the SOC may generate an alarm based on the second environmental data. Optionally, the SOC may also wake up a control unit (e.g., a CDC) and send an alarm to the CDC. For example, the SOC may wake up the CDC by sending a third wake-up signal to the CDC. After receiving the alarm, the CDC may issue an alarm based on the alarm. For example, if the target alarm level is a first alarm level, the CDC may display the first alarm on an onboard display device, such as by highlighting the alarm on the onboard screen. If the target alarm level is a second alarm level, the CDC may send a second alarm to a user terminal. Optionally, the CDC may also push corresponding video image data to the user terminal so that the user can promptly check the vehicle's status. Furthermore, the CDC may save the video image data associated with the alarm (or write the video image data associated with the alarm to disk). The video image data associated with the alarm information here can be understood as all video image data that triggers the generation of the alarm information. Optionally, after the CDC saves the video image data associated with the alarm information, the CDC can enter a dormant state. Optionally, if the SOC does not receive new second environmental data within a first period of time after the alarm information is generated, the SOC enters a dormant state.

[0230] For example, the implementation process of implementation (1) above can refer to the process shown in Figure 5, where: S1. When the vehicle is parked, a vibration signal is acquired for vibration detection, and a radar signal is acquired for radar detection. S2. Upon detecting a first trigger event, the MCU sends a first wake-up signal and second environmental data to the SOC. S3. The SOC determines whether to generate an alarm based on the second environmental data. This includes the following three branches: Branch 1: If the distance between the target mobile object and the vehicle is less than or equal to a second distance threshold, but the vibration intensity is less than the second vibration threshold, an alarm message containing a first alarm level is generated. Branch 2: If the distance between the target mobile object and the vehicle is less than or equal to the second distance threshold, and the vibration intensity is greater than or equal to the second vibration threshold, an alarm message containing a second alarm level is generated. Branch 3: If the distance between the target mobile object and the vehicle is greater than the second distance threshold, and the vibration intensity is less than the second vibration threshold, the SOC enters a dormant state. S4. If an alarm message is generated, the SOC sends the alarm message to the CDC. S5. The CDC issues a corresponding warning based on the alarm level and stores the video image data on disk. S6. The SOC enters a dormant state. Generally speaking, if the SOC does not receive new second environmental data within a first period of time after generating the alarm message, the SOC enters a dormant state. S7. The CDC enters a dormant state. Generally speaking, after the CDC saves the video image data associated with the alarm message, it can enter a dormant state.

[0231] In one possible implementation (two), if the system architecture shown in Figure 2 is used, the computing unit may be a CDC. That is, when the MCU detects abnormal vibrations in the vehicle or the APA detects the presence of moving objects around the vehicle, either the MCU or the APA can wake up the CDC. After waking up, the CDC can generate an alert based on the second environmental data and issue an alert based on the alert. For example, when the target alert level is the first alert level, the CDC can display the first alert via an onboard display device, such as by highlighting the alert on the onboard screen. When the target alert level is the second alert level, the CDC can send the second alert to the user terminal. Optionally, the CDC can also push corresponding video image data to the user terminal so that the user can promptly check the vehicle's status. Furthermore, the CDC can also save the video image data associated with the alert. Optionally, after saving the video image data associated with the alert, the CDC can enter a dormant state again. Alternatively, if the CDC does not receive new second environmental data within a first period after generating the alert, the CDC can enter a dormant state.

[0232] Exemplarily, the implementation process of the above-mentioned implementation (ii) can refer to the process shown in Figure 6, wherein: S1, when the vehicle is in a parked state, the MCU obtains a vibration signal for vibration detection. (Or, S1', when the vehicle is in a parked state, the APA obtains a radar signal for radar detection, or the APA obtains video image data for image detection. S2, when the MCU detects abnormal vibration, the MCU sends a first wake-up signal and second environmental data to the CDC. (Or, S2', when the APA detects the presence of a moving object around the vehicle, the APA sends a first wake-up signal and second environmental data to the CDC) S3, the CDC determines whether to generate an alarm message based on the second environmental data. It includes the following three branches: Branch one: When the distance between the target moving object and the vehicle is less than or equal to the second distance threshold, but the vibration intensity is less than the second vibration threshold, an alarm message containing a first alarm level is generated. Branch two : When the distance between the target moving object and the vehicle is less than or equal to the second distance threshold, and the vibration intensity is greater than or equal to the second vibration threshold, an alarm message containing a second alarm level is generated. Branch three: When the distance between the target moving object and the vehicle is greater than the second distance threshold, and the vibration intensity is less than the second vibration threshold, the CDC enters a dormant state. S4. The CDC makes corresponding warnings according to the alarm level and writes the video image data to the disk. S5. The CDC enters a dormant state. Generally speaking, after the CDC saves the video image data associated with the alarm information, the CDC can enter a dormant state again, or if the CDC does not receive new second environmental data within the first period of time after the alarm information is generated, the CDC enters a dormant state.

[0233] In an embodiment of the present application, lightweight vibration detection or visual detection, and radar detection algorithms are pre-positioned on a low-power detection unit (such as an MCU or APA), powered by a small battery. The computing unit (such as an SOC or CDC) is awakened to run the full detection algorithm only when necessary, which can save power consumption while ensuring accurate detection results.

[0234] Please refer to Figure 7, which is another flow chart of the environment detection method provided by an embodiment of the present application. As shown in Figure 7, the environment detection method includes the following steps S701 to S705. The method execution subject shown in Figure 7 can be a vehicle, or the method execution subject shown in Figure 7 can also be a chip or vehicle-mounted component in which the detection software is deployed in the vehicle. For example, the detection software can be deployed in the vehicle's CDC, MDC, APA, MCU and other vehicle-mounted components (or chips), and this application does not limit this. For the convenience of description, Figure 7 mainly uses the vehicle-mounted component in which the detection software is deployed in the vehicle as an example to illustrate the execution subject of the method. Specifically, the vehicle component can be a perception data processing module, a vibration signal processing module and a computing unit. It should be understood that if the system architecture shown in Figure 2 is adopted, then the vibration signal processing module can refer to the MCU, the perception data processing module can refer to the APA, and the computing unit can be the CDC. This embodiment is mainly illustrated by the architecture shown in Figure 2. It should be noted that FIG7 is a schematic flow chart of an embodiment of the method of the present application, showing detailed communication steps or operations of the method, but these steps or operations are merely examples, and the embodiment of the present application may also perform other operations or variations of the various operations in FIG7. In addition, the various steps in FIG7 may be performed in a different order than that presented in FIG7, and it is possible that not all operations in FIG7 need to be performed. Among them:

[0235] S701 : The MCU determines whether the vehicle generates abnormal vibration based on a vibration signal and a first vibration threshold.

[0236] In some feasible implementations, the sensor connected to the MCU may be an accelerometer. The first environmental data collected by the accelerometer is a vibration signal. The MCU can determine whether the vehicle is experiencing abnormal vibration based on the vibration signal from the accelerometer and a first vibration threshold. Specifically, if the vibration intensity indicated by the vibration signal is not less than the first vibration threshold, the MCU can determine that the vehicle is experiencing abnormal vibration; if the vibration intensity indicated by the vibration signal is less than the first vibration threshold, the MCU can determine that the vehicle is not experiencing abnormal vibration.

[0237] S702: When the MCU determines that the vehicle is vibrating abnormally, the MCU sends a second wake-up signal to the APA. In response, the APA receives the second wake-up signal from the MCU.

[0238] In some feasible embodiments, the sensors connected to the APA may include environmental perception sensors, which may specifically be vision sensors and / or radar sensors. For ease of description, the following description uses the example of an environmental perception sensor including a vision sensor and a radar sensor as an example. The first environmental data collected by the environmental perception sensor is perception data. For example, video image data collected by a vision sensor and radar signals collected by a radar sensor can both be understood as perception data.

[0239] It should be noted that when the MCU determines that the vehicle has abnormal vibration, the MCU can wake up the APA.

[0240] S703: When the APA determines, based on the perception data, that there is a moving object around the vehicle, it determines that a first triggering event is detected.

[0241] It should be understood that when the APA is awakened by the MCU, the APA can determine whether there is a moving object around the vehicle based on the radar signal or video image data. For example, when the distance between the moving object and the vehicle is less than or equal to a certain distance threshold (hereinafter referred to as the first distance threshold for ease of distinction) determined based on the radar signal, it can be determined that there is a moving object around the vehicle; when the distance between the moving object and the vehicle is greater than the first distance threshold, it can be determined that there is no moving object around the vehicle. Generally speaking, when there is a moving object around the vehicle, it can be considered that the first trigger event has been detected.

[0242] S704: When the APA detects the first trigger event, the APA sends a first wake-up signal and second environment data to the CDC. Correspondingly, the CDC receives the first wake-up signal and second environment data from the APA.

[0243] In some feasible implementations, when the APA detects the first trigger event, it may wake up the CDC and send the second environment data to the CDC.

[0244] S705: The CDC determines whether to generate alarm information based on the second environment data.

[0245] Regarding the implementation of the CDC determining whether to generate alarm information based on the second environment data, reference may be made to the relevant description in step S303 of the embodiment corresponding to FIG. 3 , which will not be elaborated here.

[0246] In an embodiment of the present application, after the MCU detects vibration, it wakes up the APA to detect vision and radar, and finally pulls up the CDC. This hierarchical wake-up method can reduce power consumption.

[0247] The above describes in detail the methods of the embodiments of the present application. The following provides an apparatus for implementing any method in the embodiments of the present application.
