DETAILED DESCRIPTION

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Figure 1 This is a schematic flowchart of an embodiment of a vehicle air conditioning control method provided in this application. (Refer to...) Figure 1 ; Figure 2 This is a schematic diagram of a pedestrian detection area provided in one embodiment of this application; Figure 3 This is an overall framework diagram of a vehicle air conditioning control method provided in an embodiment of this application.

[0023] refer to Figure 1 One embodiment of this application provides a vehicle air conditioning control method, the method including steps S11 to S13: Step S11: Perform pedestrian detection on the pedestrian detection area of ​​the vehicle to obtain a pedestrian image.

[0024] In this embodiment, the vehicle includes a sensing module and a vehicle controller. The sensing module includes an ADS system, a GPS system, and on-board sensors (for detecting air quality).

[0025] When a vehicle is moving at low speed or stationary, the risk of pedestrian interaction with the vehicle is higher. Therefore, it is necessary to adjust the air circulation mode of the vehicle's air conditioning to avoid the airflow from the air conditioning affecting the pedestrian area around the vehicle.

[0026] Based on this, refer to Figure 2 Multiple pedestrian detection zones are set up around the vehicle. The pedestrian detection zones refer to multiple areas around the vehicle. When the vehicle is at low speed or stationary, pedestrians are detected in multiple pedestrian detection zones through onboard cameras, millimeter-wave radar, infrared sensors, etc., to obtain pedestrian images of each pedestrian detection zone around the vehicle.

[0027] The pedestrian detection area includes: the pedestrian detection area in front of the vehicle ( Figure 2 The area where center lines A, B, H, and E intersect (represented by ABHE), and the pedestrian detection area on the left side of the vehicle ( Figure 2 The area where center lines B, C, E, and F intersect (represented by BCEF), and the pedestrian detection area on the right side of the vehicle (i.e. Figure 2The area where the center line B, the line C, the line G, and the line H intersect is denoted by BCGH, and the rear pedestrian detection area is denoted by BCR. Figure 2 The area where the center line C, the line D, the line H, and the line E intersect is denoted by CDHE.

[0028] Specifically, the pedestrian detection area is set by the following method: (1) Boundary line reference of the pedestrian detection area: ① All lines of the boundary line are defined based on the three-dimensional coordinate system of the test vehicle, with the vehicle center line as the Y axis, the direction perpendicular to the center line as the X axis, and the vehicle travel direction as the Z axis.

[0029] ② The outermost edge of the vehicle refers to the maximum transverse contour point after ignoring the outside rearview mirror (the maximum transverse contour point is located on the wheel arch, and in specific implementation, flexible calibration according to the definition of the specific vehicle model is required, such as defining the maximum transverse contour point of the vehicle door lower edge for some vehicle models.

[0030] ③ The line position of the boundary line needs to be dynamically adjusted according to the real-time state of the vehicle (such as steering and pitch angle), and this application uses a combination of inertial navigation, millimeter wave radar, and visual sensor fusion scheme to obtain the vehicle attitude.

[0031] (2) The boundary line definition of the pedestrian detection area is shown in Table 1: Table 1

[0032] Step S12, obtaining a pedestrian feature parameter value according to the pedestrian image, the pedestrian feature parameter value being used to represent the sensitivity of the pedestrian to air quality.

[0033] In combination with the technical solutions of the above embodiments, another embodiment of the present application further provides a vehicle-mounted air conditioner control method, in which the step S12 "obtaining a pedestrian feature parameter value according to the pedestrian image" includes steps S12-1 and S12-2: Step S12-1, obtaining an age feature of the pedestrian and a body state feature of the pedestrian according to the pedestrian image.

[0034] In this embodiment, the pedestrian image can present the pedestrian features in the plurality of pedestrian detection areas around the vehicle body, and the pedestrian features include the age feature and the body state feature of the pedestrian.

[0035] Among them, the age feature is classified according to infants, teenagers, adults, and the elderly, and the body state feature is whether the pedestrian is holding an infant / stroller, whether the pedestrian is pregnant, whether the pedestrian is using assistive devices (such as a cane or a wheelchair), and whether the pedestrian has an abnormal gait, etc. Different types of pedestrian features are embodied by specific assignments to reflect the sensitivity of different features, and the higher the sensitivity, the higher the assignment.

[0036] By performing feature analysis on the pedestrian features of each pedestrian in the pedestrian image, the pedestrian feature parameter values ​​of each pedestrian are obtained. Different types of pedestrians correspond to different pedestrian feature parameter values.

[0037] The pedestrian characteristic parameter value is a value calculated based on the age and physical condition characteristics of pedestrians, used to characterize the sensitivity of pedestrians around the vehicle to air quality.

[0038] As one example, different weights can be assigned to age features and physical condition features, and the pedestrian feature parameter values ​​for each pedestrian can be calculated based on a weighted summation method.

[0039] As one implementation method, the rules for assigning values ​​to pedestrian features are as follows:

[0040] Step S12-2: Obtain pedestrian feature parameter values ​​based on the pedestrian's age characteristics and physical condition characteristics.

[0041] For example, the formula for calculating the pedestrian characteristic parameter value PFI(t) of a vehicle at the current time t is: ; Where Age_Feature(t) is the age feature, Body_State(t) is the body state feature, w1 is the weight of the age feature, and w2 is the weight of the body state feature.

[0042] The weights of age and physical condition features can be set based on the actual project emphasis. For example, if age and physical condition features are considered equally important in pedestrian features, then w1=0.5 and w2=0.5.

[0043] Step S13: When the pedestrian characteristic parameter value meets the pedestrian characteristic triggering condition, control the vehicle's air conditioning to adjust the air circulation mode and purify the airflow to be discharged outside the vehicle.

[0044] In this embodiment, reference Figure 3 After calculating the pedestrian characteristic parameter values ​​for each pedestrian, the system determines whether the vehicle's air conditioning system needs to be adjusted and whether the exhaust air needs to be purified, based on whether the pedestrian characteristic parameter values ​​meet the pedestrian characteristic triggering conditions. If any pedestrian characteristic parameter value meets the pedestrian characteristic triggering conditions, a corresponding control command is generated to control the vehicle's air conditioning system to adjust the air circulation mode and purify the exhaust air.

[0045] As an implementation form, the pedestrian feature trigger condition can be set in the form of one or more thresholds, the pedestrian feature trigger condition can include multiple levels, and different thresholds are used to reflect the levels. When the pedestrian feature parameter value meets a certain threshold of the pedestrian feature trigger condition, the air circulation mode of the vehicle-mounted air conditioner is adjusted according to the corresponding control strategy of the level, and the air flow to be discharged outside the vehicle is purified according to the corresponding purification intensity.

[0046] Through the technical solution of the present application, the pedestrian feature of the pedestrian around the vehicle body can be detected when the vehicle is at low speed or stationary, and then based on the pedestrian feature, the age feature and the body state feature of the pedestrian are focused on through the multi-dimensional evaluation mechanism of the pedestrian feature parameter value, so as to accurately identify different types of special sensitive groups, and based on the pedestrian feature trigger condition, the air circulation mode of the vehicle-mounted air conditioner is adjusted, and the air flow to be discharged outside the vehicle is purified. Therefore, the air conditioner control of the present application is not limited to the control of the driver, but also considers the factor of the pedestrian outside the vehicle, solves the problem that the trigger factor considered by the vehicle-mounted air conditioner control is relatively single, improves the air quality adjustment area, and thus in the sensitive group scene, the air conditioner air flow can be prevented from diffusing to the outside to affect the pedestrian area while improving the comfort of the vehicle interior.

[0047] In combination with the technical solution of the above-mentioned embodiment, another embodiment of the present application further provides a vehicle-mounted air conditioner control method. In the method, the step S13 "controlling the vehicle-mounted air conditioner to adjust the air circulation mode and purifying the air flow to be discharged outside the vehicle when the pedestrian feature parameter value meets the pedestrian feature trigger condition" specifically includes steps S13-1-1 to S13-1-4. Step S13-1-1, determining an air regulation level according to the outdoor air quality index and the pedestrian feature parameter value when the pedestrian feature parameter value meets the pedestrian feature trigger condition.

[0048] In the present embodiment, the outdoor air quality index can be monitored in real time by the vehicle-mounted sensor of the vehicle, and the air regulation level is determined in combination with the outdoor air quality index and the pedestrian feature parameter value. The air regulation level represents the intensity of air regulation.

[0049] For example, when the outdoor air quality index represents that the outdoor air quality is worse or the number of target pedestrians whose pedestrian feature parameter value meets the pedestrian feature trigger condition is larger, the corresponding air regulation level is higher, and the intensity of air regulation is stronger.

[0050] As an implementation form, the air regulation level is divided into three levels, and the intensity of air regulation is sequentially first air regulation level, second air regulation level, and second air regulation level from low to high.

[0051] Step S13-1-2: When the air conditioning level is the first air conditioning level, control the vehicle air conditioner to switch to automatic circulation mode and perform first-intensity air purification on the airflow to be discharged outside the vehicle.

[0052] In this embodiment, the first air conditioning level control strategy is as follows: the air conditioning system switches to automatic circulation mode to perform first-intensity air purification on the airflow to be discharged outside the vehicle, maintains ventilation when the air quality is good, and automatically switches to internal circulation mode when the pollution level increases.

[0053] In step S13-1-3, when the air conditioning level is the second air conditioning level, the vehicle air conditioner is controlled to switch to the internal circulation mode, and the air to be discharged outside the vehicle is purified by the second intensity.

[0054] In this embodiment, the second air conditioning level control strategy is as follows: the air conditioning system switches to internal circulation mode and starts a high-efficiency air purification program (HEPA + activated carbon + negative ions), which not only protects the occupants of the vehicle, but also avoids expelling the purified air and mixing it with exhaust gas to affect pedestrians, thereby optimizing the air quality inside the vehicle. At the same time, it avoids the air conditioning airflow disturbing the exhaust gas and affecting pedestrians.

[0055] Step S13-1-4: When the air conditioning level is the third air conditioning level, control the vehicle air conditioner to switch to full internal circulation mode, close the air vents facing the outside of the vehicle, and perform third-intensity air purification on the air to be discharged outside the vehicle.

[0056] In this embodiment, the third air conditioning level control strategy is as follows: the air conditioning system switches to full internal circulation mode and closes or adjusts the direction of the air outlet to minimize the mixing and diffusion of air conditioning airflow and exhaust gas, and prevents the air conditioning airflow from disturbing the exhaust gas and affecting the pedestrian breathing area.

[0057] The purification intensity levels, from low to high, are: Level 1, Level 2, and Level 3.

[0058] In conjunction with the technical solutions of the above embodiments, another embodiment of this application also provides a vehicle air conditioning control method. In this method, when the pedestrian characteristic parameter value meets the pedestrian characteristic triggering condition, the method further includes step S21: Step S21: Based on the pedestrian images within the first target time period, determine the target pedestrian density of the target pedestrians that meet the pedestrian feature parameter values.

[0059] In this embodiment, in order to further realize precise control of the vehicle-mounted air conditioner, the pedestrian density can also be combined on the basis of the pedestrian feature. Specifically, the target pedestrian density of the target pedestrian with the pedestrian feature parameter value is determined by analyzing the pedestrians contained in the pedestrian image in the first target time period (for example, the sliding window of the last 5 seconds) within the time period.

[0060] The target pedestrian with the pedestrian feature parameter value refers to the pedestrian whose pedestrian feature parameter value meets the pedestrian feature trigger condition. The target pedestrian density of the target pedestrian is obtained by counting the proportion of the number of pedestrians whose pedestrian feature parameter value meets the pedestrian feature trigger condition (i.e., the number of target pedestrians) in all pedestrians contained in the pedestrian image in the time period.

[0061] The determination process of the number of pedestrians is as follows: The pedestrian detection area includes four parts: ABHE, BCFE, BCHG, and CDEH.

[0062] : The proportion of target pedestrians in the ABHE region detected in the first target time period t; : The proportion of target pedestrians in the BCFE region detected in the first target time period t; : The proportion of target pedestrians in the BCHG region detected in the first target time period t; : The proportion of target pedestrians in the CDEH region detected in the first target time period t; Since the exhaust of the vehicle is generally discharged at the rear side of the vehicle, in order to better reflect the importance of the pedestrian detection area CDEH at the rear side of the vehicle, a weight coefficient is introduced for the pedestrian detection area CDEH at the rear side of the vehicle, where is greater than 1.

[0063] For example, assuming = 2, and the weight of other pedestrian detection areas is 1.

[0064] The finally determined target pedestrian density is: .

[0065] The step S13 "controlling the vehicle-mounted air conditioner of the vehicle to adjust the air circulation mode and purifying the air flow to be discharged outside the vehicle in the case where the pedestrian feature parameter value meets the pedestrian feature trigger condition" specifically includes the step S13-1.

[0066] Step S13-1, in the case where the pedestrian feature parameter value meets the pedestrian feature triggering condition, according to the target pedestrian density and the pedestrian feature parameter value, the vehicle-mounted air conditioner of the vehicle is controlled to adjust the air circulation mode, and the air flow to be discharged outside the vehicle is purified.

[0067] In the embodiment, when the pedestrian feature parameter value meets the pedestrian feature triggering condition, it means that the vehicle-mounted air conditioner of the vehicle needs to be controlled to adjust the air circulation mode, and the air flow to be discharged outside the vehicle needs to be purified. Specifically, according to the value of the target pedestrian density, the air conditioning level corresponding to the target pedestrian density is determined, according to the air conditioning level corresponding to the target pedestrian density, the control strategy corresponding to the level is determined to adjust the air circulation mode of the vehicle-mounted air conditioner, and the air flow to be discharged outside the vehicle is purified according to the corresponding purification intensity.

[0068] Through the technical solutions of the above embodiments, the control strategy of air conditioning can be finely classified and controlled in combination with the pedestrian feature and the target pedestrian density.

[0069] As an implementation manner, the pedestrian density level is divided into: a first density pedestrian density level, a second density pedestrian density level, and a third density pedestrian density level, and the target pedestrian density is sequentially: the first density pedestrian density level, the second density pedestrian density level, and the third density pedestrian density level from small to large.

[0070] For example, when the target pedestrian density belongs to the first density pedestrian density level, the control strategy of the first air conditioning level is executed: the vehicle-mounted air conditioner is controlled to switch to the automatic circulation mode, and the air flow to be discharged outside the vehicle is purified at the first intensity.

[0071] When the target pedestrian density belongs to the second density pedestrian density level, the control strategy of the second air conditioning level is executed: the vehicle-mounted air conditioner is controlled to switch to the internal circulation mode, and the air flow to be discharged outside the vehicle is purified at the second intensity.

[0072] When the target pedestrian density belongs to the third density pedestrian density level, the control strategy of the third air conditioning level is executed: the vehicle-mounted air conditioner is controlled to switch to the full internal circulation mode, the air outlet facing outside the vehicle is closed, and the air flow to be discharged outside the vehicle is purified at the third intensity.

[0073] In combination with the technical solutions of the above embodiments, another embodiment of the present application further provides a vehicle-mounted air conditioner control method. In the method, in the case where the pedestrian feature parameter value meets the pedestrian feature triggering condition, the method further includes step S31: Step S31, according to the surrounding environment image of the vehicle or the location of the vehicle, the scene where the vehicle is located is determined.

[0074] In the embodiment, in order to further realize the precise control of the vehicle air conditioner, the vehicle scene can also be combined on the basis of the pedestrian feature. Specifically, the current surrounding environment image of the vehicle or the location of the vehicle is identified according to the vehicle camera, GPS positioning or ADS sensor, and the scene where the vehicle is located is determined. The scene recognition includes determining whether the vehicle is currently in a target scene in a target scene set, such as a specific sensitive area such as a school, a hospital, a residential area, etc.

[0075] The step S13 "controlling the vehicle air conditioner to adjust the air circulation mode and purify the air flow to be discharged outside the vehicle in the case that the pedestrian feature parameter value meets the pedestrian feature triggering condition" specifically includes a step S13-2.

[0076] The step S13-2 includes: in the case that the scene where the vehicle is located belongs to any target scene in the target scene set, and the pedestrian feature parameter value meets the pedestrian feature triggering condition, controlling the vehicle air conditioner to adjust the air circulation mode and purify the air flow to be discharged outside the vehicle, and the air quality demand value corresponding to each target scene in the target scene set is higher than the target demand value.

[0077] In the embodiment, on the premise that the pedestrian feature parameter value meets the pedestrian feature triggering condition, when the scene where the vehicle is located belongs to any target scene in the pre-set target scene set, the air conditioning level corresponding to the target scene is determined according to the target scene where the vehicle is located, the air circulation mode of the vehicle air conditioner is adjusted according to the control strategy corresponding to the air conditioning level of the target scene, and the air flow to be discharged outside the vehicle is purified according to the corresponding purification intensity.

[0078] The target scene set is obtained by the following method: First, a large amount of historical vehicle operation data, city air quality monitoring data and crowd activity heat map cloud data are collected by the background, and are aggregated according to geographical grid or semantic POI (school, hospital, bus station, underground parking lot, etc.), and the average air quality index AQI_s of each candidate scene in the pedestrian dense period is calculated as the air quality demand value corresponding to the candidate scene, that is, the air quality demand value is dynamically changed with the period.

[0079] Subsequently, a target demand value T is set, all candidate scenes are filtered according to the target demand value, that is, AQI_s>T is marked and written into a target scene set as a target scene, and the target scene set is regularly updated with cloud data. When the AQI_s of a target scene in the target scene set is continuously lower than T in the pedestrian dense period due to road reconstruction, traffic restriction or greening improvement, the target scene is automatically removed from the target scene set. Conversely, when the AQI_s of a non-target scene is continuously higher than T in the pedestrian dense period, the non-target scene is dynamically added to the target scene set, so that the target scene set always contains only scenes with air quality demand values higher than the target demand value.

[0080] As an implementation, the target scene can also be divided according to the size of the air quality demand value. The air quality demand value from small to large is in turn: a first grade scene, a second grade scene, and a third grade scene.

[0081] For example, when the target scene belongs to the first grade scene, a first air conditioning level control strategy is executed: control the vehicle-mounted air conditioner to switch to an automatic circulation mode, and perform air purification of a first intensity on the airflow to be discharged outside the vehicle.

[0082] When the target scene belongs to the second grade scene, a second air conditioning level control strategy is executed: control the vehicle-mounted air conditioner to switch to an internal circulation mode, and perform air purification of a second intensity on the airflow to be discharged outside the vehicle.

[0083] When the target scene belongs to the third grade scene, a third air conditioning level control strategy is executed: control the vehicle-mounted air conditioner to switch to a full internal circulation mode, close the air outlet facing outside the vehicle, and perform air purification of a third intensity on the airflow to be discharged outside the vehicle.

[0084] Through the technical solutions of the above embodiments, the control strategy of air conditioning can be finely classified and controlled in combination with pedestrian features and vehicle scenes.

[0085] In combination with the technical solutions of the above embodiments, another embodiment of the present application further provides a vehicle-mounted air conditioner control method. In the method, when the pedestrian feature parameter value meets the pedestrian feature triggering condition, the method further includes step S41: Step S41: determining a target pedestrian growth rate of the target pedestrian according to the pedestrian image in the second target time period.

[0086] In this embodiment, in order to further realize precise control of the vehicle-mounted air conditioner, the target pedestrian growth rate can also be combined with the pedestrian feature. If it is detected that the target pedestrian growth rate presents an accelerating trend with time, it means that more target pedestrians will enter the detection area, and the air conditioner control is triggered in advance.

[0087] Specifically, by analyzing the pedestrians contained in the pedestrian images in a second target time period (for example, a sliding window of the last 10 seconds), a target pedestrian growth rate of the target pedestrian with the pedestrian feature parameter value among the pedestrians contained in the pedestrian images in the time period is determined.

[0088] The target pedestrian growth rate refers to the growth rate of the target pedestrian with the pedestrian feature parameter value in the second target time period.

[0089] The step S13 "controlling the air circulation mode of the vehicle-mounted air conditioner of the vehicle and purifying the air flow to be discharged outside the vehicle in the case where the pedestrian feature parameter value meets the pedestrian feature triggering condition" specifically includes a step S13-3.

[0090] Step S13-3, in the case where the target pedestrian growth rate is greater than the growth rate threshold and the pedestrian feature parameter value meets the pedestrian feature triggering condition, controlling the air circulation mode of the vehicle-mounted air conditioner of the vehicle and purifying the air flow to be discharged outside the vehicle.

[0091] In this embodiment, according to the target pedestrian growth rate, it can be determined whether the target pedestrians are increasing or not, so that when the target pedestrians are rapidly increasing, based on the target pedestrian growth rate, the target pedestrian density in the future is predicted, based on the target pedestrian density in the future, the air conditioning level corresponding to the target pedestrian density is adjusted in advance, according to the determined air conditioning level, the control strategy corresponding to the level is determined to adjust the air circulation mode of the vehicle-mounted air conditioner in advance, and the air flow to be discharged outside the vehicle is purified in advance according to the corresponding purification intensity.

[0092] In one embodiment, the density pedestrian density level corresponding to the future target pedestrian density is determined.

[0093] For example, when the future target pedestrian density belongs to the first density pedestrian density level, the control strategy of the first air conditioning level is executed: controlling the vehicle-mounted air conditioner to switch to the automatic circulation mode, and purifying the air flow to be discharged outside the vehicle with the first intensity of air purification.

[0094] When the future target pedestrian density belongs to the second density pedestrian density level, the control strategy of the second air conditioning level is executed: controlling the vehicle-mounted air conditioner to switch to the internal circulation mode, and purifying the air flow to be discharged outside the vehicle with the second intensity of air purification.

[0095] When the future target pedestrian density belongs to the third density pedestrian density level, the control strategy of the third air conditioning level is executed: controlling the vehicle-mounted air conditioner to switch to the full internal circulation mode, closing the air outlet facing outside the vehicle, and purifying the air flow to be discharged outside the vehicle with the third intensity of air purification.

[0096] Through the technical solutions of the above-mentioned embodiments, the air circulation mode can be adjusted in advance and the air flow to be discharged outside the vehicle can be purified according to the target pedestrian growth rate.

[0097] In combination with the technical solutions of the above-mentioned embodiments, another embodiment of the present application further provides a vehicle-mounted air conditioner control method, in which after the step S13 of “controlling the vehicle-mounted air conditioner of the vehicle to adjust the air circulation mode and purify the air flow to be discharged outside the vehicle”, the method further includes steps S14 and S15: Step S14, collecting the air quality index of the pedestrian detection area.

[0098] Step S15, in the case that the air quality index of the pedestrian detection area does not reach the air quality index requirement value corresponding to the pedestrian characteristic parameter value, controlling the range extender of the vehicle to reduce the exhaust emission or stop running.

[0099] In this embodiment, after adjusting the air circulation mode of the vehicle-mounted air conditioner and purifying the air flow to be discharged outside the vehicle, the air quality index AQI_now of the pedestrian detection area after air conditioning is further collected in real time by the vehicle-mounted sensor; if AQI_now is still lower than the air quality index requirement value AQI_req corresponding to the pedestrian characteristic parameter value, the range extender (APU / engine generator unit) of the vehicle is further triggered for control, such as reducing power, delaying start or completely stopping, so as to directly reduce exhaust emission until AQI_now≥AQI_req, and to ensure that the sensitive population is always in the standard air environment.

[0100] Wherein, the higher the pedestrian characteristic parameter value is, the higher the corresponding air quality index requirement value is.

[0101] In addition, the technical solutions of the present application can further collect the power output data (current power, battery capacity) of the range extender, the perception results (pedestrian characteristics, target pedestrian density, target pedestrian growth rate scene) of the ADS in real time through the VCU, and visually present through the dynamic icons and instrument panel of the central control display screen. At the same time, the running mode (external circulation / internal circulation) of the air conditioning system, the air purification intensity, the air quality sensor data are collected, and are displayed in linkage with the range extender state.

[0102] In specific implementation, the following technologies are adopted: a. Real-time dynamic visualization: through the dynamic chart and icon of the central control display screen, the power output state of the range extender is displayed in real time in combination with color coding (green represents 100% full power operation, yellow represents 50% power operation, red represents 30% power operation, and gray represents range extender off) b. Multi-dimensional data integration: In the visualization interface, the extended-range power, battery power, current scene type (such as "high-density pedestrian area" or "school area"), and environmental parameters (such as noise level and AQI index) are displayed simultaneously. The air conditioning operation mode and air purification intensity are also displayed as key parameters in real time, forming a multi-dimensional data interface to help users understand the system status comprehensively. In specific implementation, the sensor data is synchronized with the VCU through the CAN bus, with a delay of less than 0.5 seconds.

[0103] c. Historical trend analysis: The system has a built-in data recording module that can store the extended-range power curve, scene switching record, air conditioning system operation mode change, and air purification system working time, helping users analyze energy consumption patterns and optimize driving habits.

[0104] Scene-based extended-range & air purification system adjustment prompts The design logic and innovation points of the extended-range adjustment prompts for the scene are as follows: ① Scene-driven multi-modal prompts: According to the triggering conditions (such as pedestrian density and environmental noise), the corresponding prompt content is automatically matched, and the air conditioning system is switched to the internal circulation mode, and the air purification system is started, to generate more complete prompt information, ensuring that the information is highly relevant to the scene.

[0105] ② Scenario-based explanation and suggestion: The prompt content not only explains the current operation (such as power adjustment), but also explains the reason (such as "due to detection of a dense pedestrian area") and provides driving suggestions (such as "suggest reducing speed to 30 km / h"). At the same time, it prompts whether the air conditioning system has been switched to the internal circulation mode to reduce the impact of exhaust gas diffusion on pedestrians.

[0106] ③ Hierarchical prompt mechanism: According to the scene emergency level, the intensity and frequency of the prompt are adjusted (such as repeating the prompt every 30 seconds in a high-density scene to avoid information overload).

[0107] In the specific implementation of the present application, the details are as follows: a. Central control screen / instrument image display: When the above-mentioned scene is triggered, the central control screen pops up a dynamic icon (such as a dense pedestrian icon + a red warning box) and labels the scene type. At the same time, it displays icons indicating whether the air conditioning system has been switched to the internal circulation mode and whether the air purification system has been started.

[0108] b. Central control screen / instrument text pop-up prompt: Example 1: High-density pedestrian scene: The pop-up window displays "The current area is densely populated with pedestrians, and the extended-range power has been reduced to 30% to reduce emissions. Suggest reducing speed to 30 km / h." Example 2: Sensitive Area (School / Hospital): Pop-up displays "Entering school area, range extender is off, switching to pure electric mode. Please keep speed below 20 km / h." c. Sound prompt: (1) Voice broadcast: Clear voice is played through the in-car speaker (e.g. "Detected increased pedestrian density, range extender power adjusted to 50%").

[0109] (2) Warning sound effect: In the case of extremely high density, a short warning sound is played (e.g. "Tik", in actual implementation, it can be 2HZ-4HZ according to the emergency situation prompt sound) to attract the driver's attention, but avoid excessive interference.

[0110] 3. User configurable switch settings The design logic and innovation points of user configurable switch settings are as follows: ① Balance between user autonomy and system safety: Allow users to manually override the automatic mode, but the system retains priority control in emergency situations (e.g. force on range extender when battery level is below 10%).

[0111] ② Combination of intelligent recommendation and customization: Users can save personalized settings for the range extender (e.g. "priority silent mode" or "energy saving mode"), while the system recommends optimization based on historical behavior. The system can also recommend air conditioning system operation strategies (e.g. "recommend starting air purification system").

[0112] ③ Multi-level control: Provide "basic mode" (automatic / manual switching) and "advanced mode" (customizable power threshold, scene response sensitivity) for different users to choose.

[0113] In the specific implementation of the present application, the details are as follows: a. Basic mode: Automatic mode: The system automatically adjusts the range extender according to the logic scenarios described above (default option).

[0114] Manual mode: Users can directly select the range extender "full power" "50%" "30%" or "off", and set the effective time (e.g. "continuous manual mode" or "only for this trip").

[0115] b. Advanced mode: Scene sensitivity: Users can adjust the sensitivity of pedestrian density triggering Environmental priority: In "high noise / high pollution" scenarios, users can choose "preferentially turn off the range extender" or "maintain power to maintain performance".

[0116] c. Save and restore: Users can save multiple preset configurations (e.g. "city commuting mode" "long distance travel mode") and switch them with one key.

[0117] Automatically load the last used configuration at each start, or recommend region-adapted presets based on GPS positioning (e.g. automatically switch to "low noise mode" when entering a school zone).
