[0002] Currently, with the continuous increase in car ownership and the ongoing improvement in intelligence, while Sentry Mode provides a guarantee for vehicle parking safety, it also has many problems during operation. On the one hand, for Sentry Mode to function properly, millimeter-wave radar or ultrasonic radar needs to continuously transmit and receive signals to detect information such as the distance, speed, and direction of surrounding objects. This causes all the vehicle's sensors to operate continuously, constantly transmitting and receiving signals, resulting in significant power consumption. On the other hand, the large amount of data collected by the sensors also needs to be transmitted to the electronic control unit in real time for analysis and processing to determine collision risks, a process that consumes a large amount of power.

When the vehicle executes the second preset duration according to the current monitoring strategy corresponding to the medium risk level in sentry mode, if the environmental parameters are all less than the threshold within a second preset number of time windows, then the vehicle is controlled to execute the current monitoring strategy corresponding to the low risk level. When the vehicle executes the first preset duration in sentry mode according to the current monitoring strategy corresponding to the low-risk level, if the environmental parameters are all less than the threshold within a third preset number of time windows, then the monitoring equipment in the direction of the anomaly source is turned off.

[0024] Currently, with the continuous increase in car ownership and the ongoing improvement in intelligence, while Sentry Mode provides a guarantee for vehicle parking safety, it has several problems during operation. On the one hand, for Sentry Mode to function properly, millimeter-wave or ultrasonic radar needs to continuously transmit and receive signals to detect information such as the distance, speed, and direction of surrounding objects. This requires all the vehicle's sensors to operate continuously, constantly sending and receiving signals, resulting in significant power consumption. On the other hand, the large amount of data collected by the sensors also needs to be transmitted in real time to the electronic control unit for analysis and processing to determine collision risk, a process that consumes a significant amount of power. Therefore: Figure 1 A flowchart illustrating an embodiment of the vehicle sentry mode low-power control method provided in this application is shown. This method is executed by a vehicle sentry mode low-power control device. Please refer to... Figure 1 As shown, the method includes the following steps: Step S110: Use the environmental sensor array deployed on the vehicle to collect the current environmental parameters of the environment in which the vehicle is located.
[0025] The environmental sensor array refers to a collection of various types of sensors deployed on the vehicle to collaboratively collect multi-dimensional physical parameters of the vehicle's environment. Current environmental parameters refer to the real-time environmental status data of the vehicle's surroundings acquired through the environmental sensor array.
[0026] Step S120: Determine the current global risk level of the vehicle based on the current environmental parameters.
[0027] The current global risk level refers to the comprehensive rating of vehicle safety threats determined by integrating real-time data collected by the environmental sensor group and surrounding environmental status data. It is divided into three levels: low risk, medium risk, and high risk.
[0028] Step S130: Based on the current global risk level, determine the current monitoring strategy of the vehicle in sentry mode and control its execution.
[0029] Sentinel mode refers to a safety monitoring mode activated when the vehicle is parked with the engine off. It uses an environmental sensor array to perceive the external environment and dynamically adjusts monitoring strategies to ensure vehicle safety. The current monitoring strategy refers to a dynamically formulated equipment control plan based on the current overall risk level, including sensor acquisition frequency settings, monitoring equipment start / stop rules, and duration.
[0030] The technical solution of this embodiment can effectively reduce the power consumption of continuous sensor operation and data transmission processing in the vehicle in sentry mode, reduce the overall power consumption of the vehicle, improve the energy efficiency when the vehicle is parked, and ensure the safety of the vehicle when parked.
[0031] In one alternative embodiment, the environmental sensor group includes: a light sensor, a vibration sensor, and a sound sensor; step S110 further includes: The light sensor is used to collect the current light intensity value of the environment in which the vehicle is located.
[0032] Among them, the light sensor refers to a device used to detect the ambient light intensity of the vehicle's surroundings. By collecting the current light intensity value (in lux), it determines the day / night environment and abnormal strong light flicker. The current light intensity value refers to the quantitative data of ambient light brightness measured in real time by the light sensor, which is used to determine the light risk level.
[0033] The vibration sensor is used to collect the current vibration amplitude value of the environment in which the vehicle is located.
[0034] Vibration sensors are devices used to detect the mechanical vibrations experienced by a vehicle. They identify physical impact events such as collisions and scratches by collecting the current vibration amplitude value (measured in gravitational acceleration). The current vibration amplitude value refers to the quantitative data of the vehicle's physical vibration intensity detected in real time by the vibration sensor, which is used to determine the vibration risk level.
[0035] The sound sensor is used to collect the current ambient decibel value of the environment in which the vehicle is located.
[0036] Among them, a sound sensor refers to a device used to detect the characteristics of ambient sound waves. It identifies abnormal sounds or high-frequency noises by collecting the current ambient decibel value (in dB). The current ambient decibel value refers to the quantitative data of ambient sound intensity captured in real time by the sound sensor, which is used to determine the sound risk level.
[0037] Among the above-mentioned optional methods, by specifying that the environmental sensor group includes light, vibration, and sound sensors, and specifically collecting light intensity, vibration amplitude, and ambient decibel values, the collected environmental parameters are more comprehensive, providing a basis for accurately determining the risk level and formulating reasonable monitoring strategies, and further improving the safety of vehicles in sentry mode.
[0038] In an alternative embodiment, step S120 further includes: Based on the current light intensity value, the current light risk level of the vehicle is determined.
[0039] The current light risk level refers to the hazard level (0-3) classified according to the current light intensity value and its changing trend. Specifically: ① If the current light intensity value is ≤500 lux / s, the current light risk level is determined to be level 0; ② If the current light intensity value is >500 lux / s, the current light risk level is determined to be level 1; ③ If the current light intensity value is >1000 lux / s, the current light risk level is determined to be level 2; ④ If the current light intensity value is >2000 lux / s, the current light risk level is determined to be level 3.
[0040] Based on the current vibration amplitude value, the current vibration risk level of the vehicle is determined.
[0041] The current vibration risk level refers to the danger level (0-3) classified according to the current vibration amplitude and its duration. Specifically: ① If the current vibration amplitude is ≤1.5g, the current vibration risk level is determined to be level 0; ② If the current vibration amplitude is >1.5g and lasts for 0.3s, the current vibration risk level is determined to be level 1; ③ If the current vibration amplitude is >3g and lasts for 0.2s (or a specific vibration waveform exists), the current vibration risk level is determined to be level 2; ④ If the current vibration amplitude is >8g and lasts for 0.1s (or multiple vibrations are superimposed), the current vibration risk level is determined to be level 3.
[0042] It should be noted that if the current vibration amplitude value is greater than the threshold corresponding to the corresponding vibration risk level but does not exceed the duration corresponding to the corresponding vibration risk level, then the vibration risk level will be reduced by 1 level from the original vibration risk level (if there is no original vibration risk level, then it will be directly determined as the lower vibration risk level 1). For example, if the original vibration risk level is 1, and the current vibration amplitude value is >1.5g but only lasts for 0.2s, then the current vibration risk level will be determined as 0; if there is no original vibration risk level, then the current vibration risk level will be directly determined as 1.
[0043] The current sound risk level of the vehicle is determined based on the current ambient decibel value.
[0044] The current sound risk level refers to the danger level (0-3) classified according to the current ambient decibel value, frequency characteristics, and duration. Specifically: ① If the current ambient decibel value is ≤80dB, the current sound risk level is determined to be level 0; ② If the current ambient decibel value is >80dB and lasts for 1 second, the current sound risk level is determined to be level 1; ③ If the current ambient decibel value is >90dB and lasts for 0.5 seconds (or a sharp high-frequency sound >5kHz), the current sound risk level is determined to be level 2; ④ If the current ambient decibel value is >100dB and lasts for 0.3 seconds (or there is an abnormal high-frequency continuous sound), the current sound risk level is determined to be level 3.
[0045] It should be noted that if the current ambient decibel level is greater than the threshold corresponding to the sound risk level but does not exceed the duration corresponding to the sound risk level, the sound risk level will be reduced by one level (if no original sound risk level exists, it will be directly determined as the lower level 1). For example, if the original sound risk level is 1, and the current ambient decibel level is >80dB but only lasts for 0.5s, the current sound risk level will be determined as 0; if no original sound risk level exists, the current sound risk level will be directly determined as 1.
[0046] By integrating the current light risk level, the current vibration risk level, and the current sound risk level, the current global risk level is determined.
[0047] The current global risk level is specifically divided into three categories: low risk, medium risk, and high risk. The current global risk level is determined by the superposition value of the current light risk level, current vibration risk level, and current sound risk level. Specifically: ① If the superposition value is 0-3, the current global risk level is determined to be low risk; ② If the superposition value is 4-7, the current global risk level is determined to be medium risk; ③ If the superposition value is 8-9, the current global risk level is determined to be high risk.
[0048] Among the above-mentioned optional methods, specific risk levels are determined based on various environmental parameters and integrated to obtain a global risk level. This enables an accurate assessment of the environmental risks of the vehicle, providing an accurate basis for subsequent targeted monitoring strategies based on different risk levels, and enhancing the vehicle's adaptability and safety in different environments.
[0049] In one optional approach, the current global risk level is: low risk level, medium risk level, or high risk level; the step of determining the current monitoring strategy of the vehicle in sentry mode based on the current global risk level includes: When the current global risk level is low risk, the current monitoring strategy is as follows: set the acquisition frequency of the light sensor to the first light acquisition frequency, the acquisition frequency of the vibration sensor to the first vibration acquisition frequency, the acquisition frequency of the sound sensor to the first sound acquisition frequency, activate the monitoring device in the direction of the abnormal source, and continue for a first preset duration.
[0050] The default values for the first light acquisition frequency are 10Hz, the first vibration acquisition frequency, and the first sound acquisition frequency. The default value range for the first preset duration is 30s-60s.
[0051] It should be noted that the monitoring equipment for the direction of the abnormal source refers to a local monitoring device that is activated in a specific direction based on the location of the abnormal signal detected by the light sensor, vibration sensor and sound sensor when the vehicle is in a low-risk level. Specifically, it includes vehicle-mounted cameras and radar probes in the direction of the abnormal signal source.
[0052] When the current global risk level is medium risk, the current monitoring strategy is as follows: set the acquisition frequency of the light sensor to the second light acquisition frequency, the acquisition frequency of the vibration sensor to the second vibration acquisition frequency, the acquisition frequency of the sound sensor to the second sound acquisition frequency, turn on the main monitoring equipment, and continue for the second preset duration.
[0053] The default values for the second light acquisition frequency are 20Hz, the second vibration acquisition frequency, and the second sound acquisition frequency. The default preset duration is 2-5 minutes.
[0054] It should be noted that the main monitoring equipment refers to the basic monitoring unit combination that is activated when the vehicle is at a medium-risk level, covering the core area of the vehicle. This includes front and rear cameras and millimeter-wave radars on both sides of the vehicle body, which achieve basic safety coverage by alternating data collection.
[0055] When the current global risk level is high risk level, the current monitoring strategy is as follows: set the acquisition frequency of the light sensor to the third light acquisition frequency, the acquisition frequency of the vibration sensor to the third vibration acquisition frequency, the acquisition frequency of the sound sensor to the third sound acquisition frequency, turn on the whole vehicle monitoring equipment, and continue for the third preset duration.
[0056] The default values for the third light acquisition frequency are 50Hz, the third vibration acquisition frequency, and the third sound acquisition frequency. The default preset duration is 3-5 minutes.
[0057] It should be noted that the full vehicle monitoring equipment refers to a full-dimensional monitoring system that is forcibly activated when the vehicle is at a high-risk level. This system includes 360° surround view cameras, omnidirectional millimeter-wave radar, and ultrasonic sensors, and is linked to an audible and visual alarm device for continuous full-load monitoring.
[0058] Furthermore, the ranges for each frequency and duration mentioned above can be set according to actual conditions, and no restrictions are set here. Only the following conditions must be met: ① First light acquisition frequency < Second light acquisition frequency < Third light acquisition frequency; ② First vibration acquisition frequency < Second vibration acquisition frequency < Third vibration acquisition frequency; ③ First sound acquisition frequency < Second sound acquisition frequency < Third sound acquisition frequency.
[0059] In this embodiment, after dynamically adjusting the sensor's acquisition frequency, the sensor's conversion frequency is adjusted synchronously. The conversion frequency affects the sensor's response speed and processing efficiency to physical signals. A higher conversion frequency allows for more timely conversion of physical signals into processable electrical signals, facilitating subsequent signal processing and analysis. Insufficient conversion frequency may cause the sensor's output signal to lag behind changes in the actual physical quantity.
[0060] Among the above-mentioned optional methods, corresponding monitoring strategies are formulated based on different global risk levels, and the acquisition frequency of each sensor and the opening range and duration of monitoring equipment are reasonably set. This optimizes the resource allocation of the vehicle in sentry mode, which can not only ensure vehicle safety monitoring, but also effectively reduce the overall power consumption of the vehicle and improve the energy efficiency when the vehicle is parked.
[0061] In an alternative approach, the method further includes: When the vehicle executes the third preset duration according to the current monitoring strategy corresponding to the high-risk level in sentry mode, if the environmental parameters are all less than the threshold within a first preset number of time windows, then the vehicle is controlled to execute the current monitoring strategy corresponding to the medium-risk level.
[0062] The first preset quantity is 10 by default, and the time window is 1 second by default, but can be set according to actual conditions; no limit is set here. The default thresholds for environmental parameters are: vibration amplitude < 1g, ambient decibel < 60dB, and light intensity < 500 lux / s.
[0063] It should be noted that when a high-risk level is triggered, continuous high-frequency data collection will be maintained for a third preset duration to ensure that the complete process of the event and its subsequent impact are recorded. For example, after a vehicle collision, high-frequency data collection will continue for at least 3 minutes to avoid the risk of secondary accidents or residual environmental hazards going unmonitored.
[0064] When the vehicle executes the second preset duration according to the current monitoring strategy corresponding to the medium risk level in sentry mode, if the environmental parameters are all less than the threshold within a second preset number of time windows, then the vehicle is controlled to execute the current monitoring strategy corresponding to the low risk level.
[0065] The second preset quantity is 10 by default, and the time window is 1 second by default. However, these can be set according to actual conditions, and there is no limit here.
[0066] When the vehicle executes the first preset duration in sentry mode according to the current monitoring strategy corresponding to the low-risk level, if the environmental parameters are all less than the threshold within a third preset number of time windows, then the monitoring equipment in the direction of the anomaly source is turned off.
[0067] The third preset quantity is 10 by default, and the time window is 1 second by default. However, it can be set according to the actual situation, and there is no limit here.
[0068] It should be noted that when the monitoring equipment in the direction of the abnormal source is turned off, it means that the vehicle has re-entered normal monitoring.
[0069] Among the above-mentioned optional methods, by gradually reducing the sampling frequency, the problem of missed detection caused by frequent switching or premature frequency reduction is avoided, thus realizing dynamic energy saving of the vehicle in sentry mode, avoiding unnecessary energy waste, and improving the power consumption control level when the vehicle is parked.
[0070] In an alternative approach, the method further includes: When the current global risk level is high, the vehicle is controlled to trigger an alarm.
[0071] The alarm notification methods include: ① emitting a periodic horn at 85-100dB through the vehicle's loudspeaker, with a frequency of 2-5Hz; ② performing high-frequency flashing (flashing frequency 3-8Hz) through the vehicle's headlights and taillights, with the flashing pattern synchronized with the horn frequency.
[0072] Among the above-mentioned optional methods, an alarm is triggered when the overall risk level is high, which promptly informs the vehicle owner or relevant personnel of the dangerous state of the vehicle, enhances the vehicle's safety protection capabilities when parked, and effectively reduces the risk of vehicle damage.
[0073] In an alternative approach, the method further includes: Based on the current light intensity value, the current shooting parameters of each monitoring device on the vehicle in the sentry mode are determined so that each monitoring device can perform monitoring according to the current shooting parameters.
[0074] The current shooting parameters refer to the combination of exposure parameters required by the monitoring equipment, specifically including the matching settings of ISO value, aperture size, and shutter speed.
[0075] In the above-mentioned optional methods, the shooting parameters of the monitoring equipment are determined according to the light intensity value, so that the monitoring equipment can monitor with appropriate parameters under different lighting conditions, thereby improving the monitoring effect and quality. At the same time, it also helps to further optimize the power consumption control in the vehicle sentry mode and improve the overall performance of the vehicle.

When the vehicle executes the second preset duration according to the current monitoring strategy corresponding to the medium risk level in sentry mode, if the environmental parameters are all less than the threshold within a second preset number of time windows, then the vehicle is controlled to execute the current monitoring strategy corresponding to the low risk level. When the vehicle executes the first preset duration in sentry mode according to the current monitoring strategy corresponding to the low-risk level, if the environmental parameters are all less than the threshold within a third preset number of time windows, then the monitoring equipment in the direction of the anomaly source is turned off.
