Detailed Implementation

[0026] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0028] The vehicle control method, vehicle control device, electronic device, and readable storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0029] The vehicle control method can be applied to the terminal, and can be executed by the hardware or software in the terminal.

[0030] The terminal includes, but is not limited to, portable communication devices such as mobile phones or tablets with touch-sensitive surfaces (e.g., touchscreen displays and / or touchpads). It should also be understood that, in some embodiments, the terminal may not be a portable communication device, but rather a desktop computer with touch-sensitive surfaces (e.g., touchscreen displays and / or touchpads).

[0031] The following embodiments describe a terminal including a display and a touch-sensitive surface. However, it should be understood that the terminal may include one or more other physical user interface devices such as a physical keyboard, mouse, and joystick.

[0032] The vehicle control method provided in this application embodiment can be executed by an electronic device or a functional module or entity in an electronic device that can implement the vehicle control method. The electronic devices mentioned in this application embodiment include, but are not limited to, mobile phones, tablets, computers, cameras, and wearable devices. The vehicle control method provided in this application embodiment will be described below using an electronic device as the execution subject.

[0033] like Figure 1 As shown, the vehicle control method includes steps 110 and 120.

[0034] Step 110: Obtain VOC gas data in the passenger compartment collected by the VOC sensor module and odor data in the passenger compartment collected by the odor sensor module. In this step, VOC sensor modules and odor sensor modules can be installed in the passenger compartment of the vehicle.

[0035] The VOC sensor module can be used to collect VOC gas data of various types, detect the concentration levels of various types of VOC gases, and convert the detection signals into digital data to form VOC gas data.

[0036] Odor sensor modules can be used to collect odor signals in the air inside the passenger cabin and convert the detected signals into digital data to form odor data.

[0037] VOC gas data and odor data can be electrical signal data used to characterize the concentration of a gas or odor.

[0038] The odor sensor module detects different odor data depending on the gas concentration.

[0039] In some embodiments, the VOC sensor module may include multiple VOC sensor units.

[0040] Each sensor unit is sensitive to a specific type of VOC gas, and each sensor unit has a specific sensitive material and detection range. Through multi-component synergistic detection, accurate identification of a variety of VOC gases can be achieved.

[0041] For example, multiple VOC sensor units may include: an acetaldehyde sensor unit (for detecting the concentration of acetaldehyde gas, which is commonly found in automotive plastic parts and textiles), a formaldehyde sensor unit (for detecting the concentration of formaldehyde gas, which is commonly found in automotive trim materials and adhesives), a toluene sensor unit (for detecting the concentration of toluene gas, which is commonly found in automotive paints or adhesives), a TVOC (Total Volatile Organic Compounds) sensor unit (for measuring the concentration level of TVOC), a benzene sensor unit (for detecting the concentration of benzene gas), a xylene sensor unit (for detecting the concentration of gases such as o-xylene, m-xylene, and para-xylene), an ammonia sensor unit (for detecting the concentration of ammonia gas), and a hydrogen sulfide sensor unit (for detecting the concentration of hydrogen sulfide), etc., which are not limited in this application.

[0042] In some embodiments, the odor sensor module may include a plurality of odor sensor units.

[0043] Each sensor unit is sensitive to a specific type of odor substance, and each sensor unit has a specific sensitive material and detection range. It can collect odor characteristic parameters in the passenger cabin through multi-component synergistic detection.

[0044] For example, multiple odor sensor units may include: an olefin compound sensor unit (for detecting changes in the concentration of olefin organic compounds), an alkane compound sensor unit (for detecting the odor characteristics of alkane organic compounds), a benzene series compound sensor unit (for quantitative detection of benzene series compounds), an aldehyde series compound sensor unit (for measuring the concentration level of aldehyde series compounds), an alcohol sensor unit (for detecting the concentration level of short-chain alcohols such as ethanol and isopropanol), a ketone sensor unit (for detecting the concentration level of carbonyl compounds such as acetone and butanone), and a sulfur compound sensor unit (for detecting the concentration level of sulfur-containing organic compounds such as methanethiol and dimethyl sulfide), etc., which are not limited in this application.

[0045] Step 120: Process VOC gas data and odor data to control vehicle operation.

[0046] In this step, the air quality in the passenger compartment can be evaluated based on VOC gas data and odor data, and the vehicle operation can be controlled according to the quality evaluation results.

[0047] For example, if the air quality in the passenger compartment is determined to be poor based on VOC gas data and odor data, the vehicle's air purification program can be activated.

[0048] If the air quality level in the passenger cabin is determined to be good based on VOC gas data and odor data, there is no need to activate the air purification program, and the air level in the passenger cabin can be continuously monitored.

[0049] In this application, as Figure 2 As shown, VOC sensor modules and odor sensor modules are installed in the passenger cabin, which can simultaneously detect odor and VOC gas in the passenger cabin. The "dual-dimensional detection" system solves the shortcomings of related technologies that can only achieve odor recognition or only achieve VOC detection, and realizes a comprehensive judgment of the air quality in the passenger cabin.

[0050] According to the vehicle control method provided in the embodiments of this application, by setting a VOC sensor module and an odor sensor module in the passenger compartment to detect VOC gas data and odor data in the passenger compartment, VOC detection and odor recognition can be completed simultaneously. Then, the vehicle operation can be controlled based on the detected VOC gas data and odor data to optimize the air quality in the passenger compartment when the air quality is poor. This achieves dynamic optimization control of the passenger compartment control quality and meets the user's requirements for the quality of the in-vehicle environment.

[0051] In some embodiments, step 120 may include: Feature extraction was performed on VOC gas data and odor data respectively to obtain VOC feature data and odor feature data; Vehicle operation is controlled based on VOC and odor characteristic data.

[0052] In this embodiment, the original signals (VOC gas data and odor data) can be denoised, amplified, and standardized to ensure the accuracy of the signals. Then, feature extraction can be performed to obtain VOC feature data and odor feature data.

[0053] It can classify and identify VOC characteristic data and odor characteristic data, and convert the analysis results into control signals to control vehicle operation based on the control signals.

[0054] In some embodiments, controlling vehicle operation based on VOC characteristic data and odor characteristic data may include: The first control command is obtained based on the relationship between VOC feature data and VOC gas concentration threshold. The second control command is obtained based on VOC characteristic data and odor characteristic data; The vehicle is controlled to operate based on at least one of the first control command and the second control command.

[0055] In this embodiment, the first control command includes whether or not to control the operation of the air purification device in the vehicle.

[0056] The second control command includes whether or not to control the operation of the air purification device in the vehicle.

[0057] Air purification devices may include air conditioners, etc.

[0058] The passenger compartment control quality can be determined based on a "two-level analysis mode". For example, the first level of analysis can be performed on VOC characteristic data based on a preset VOC gas concentration threshold to complete the detection of VOC concentration in the passenger compartment and make a preliminary determination on whether the air purification device in the vehicle needs to be controlled. Then, the second level of analysis can be performed by combining VOC characteristic data and odor characteristic data to complete the odor determination in the passenger compartment. Finally, the air purification device can be controlled based on the results of the two levels of determination.

[0059] Alternatively, a first-level analysis can be performed based on VOC characteristic data and odor characteristic data to determine the odor in the passenger cabin. Then, a second-level analysis can be performed on the VOC characteristic data based on a preset VOC gas concentration threshold to detect the VOC concentration in the passenger cabin. Finally, the air purification device can be controlled based on the results of the two levels of determination. The priority of the determination and analysis can be selected based on user needs, etc., which is not limited in this application.

[0060] VOC gas concentration thresholds can be preset. Different types of VOC feature data correspond to different VOC gas concentration thresholds. For example, the VOC gas concentration threshold for acetaldehyde can be set to 0.04 mg / m³, the VOC gas concentration threshold for formaldehyde can be set to 0.08 mg / m³, the VOC gas concentration threshold for toluene can be set to 0.5 mg / m³, and the VOC gas concentration threshold for TVOC can be set to 2 mg / m³. Alternatively, other values ​​can be set, which are not limited in this application.

[0061] By comparing VOC characteristic data with VOC gas concentration thresholds, VOC characteristic data can be analyzed to complete the detection of VOC concentration in the passenger cabin, thereby determining the first control command.

[0062] By combining VOC characteristic data and odor characteristic data, the odor of the occupant cabin can be determined to identify the second control command.

[0063] The following example illustrates step 120 by performing a first-level analysis of VOC feature data based on a preset VOC gas concentration threshold, followed by a second-level analysis combining VOC feature data and odor feature data.

[0064] In some embodiments, the first control command, derived based on the relationship between VOC feature data and VOC gas concentration threshold, may include: If the VOC characteristic data is greater than the VOC gas concentration threshold, the first control command is determined to include the need to control the operation of the air purification device in the vehicle.

[0065] In this embodiment, such as Figure 2 As shown, when the user starts the vehicle or remotely starts the air conditioner, the occupant cabin odor recognition and VOC detection system are activated simultaneously. The system collects VOC gas data based on the VOC sensor module and odor data based on the odor sensor module.

[0066] The signal processing and data analysis module can extract VOC gas data and odor data, process the VOC gas data into VOC feature data (data1), and process the odor data into odor feature data (data2).

[0067] Then, the concentration of VOC feature data can be judged to exceed the preset VOC gas concentration threshold. If the VOC feature data is greater than the preset VOC gas concentration threshold, the air purification program can be started and the first control command can be determined to include the need to control the operation of the air purification device.

[0068] If any VOC gas data collected by the VOC sensor unit in the VOC sensor module exceeds the preset VOC gas concentration threshold (e.g., acetaldehyde concentration > 0.04 mg / m³, formaldehyde concentration > 0.08 mg / m³, toluene concentration > 0.5 mg / m³, TVOC concentration > 2 mg / m³), the air purification program can be activated.

[0069] In some embodiments, the first control command, derived based on the relationship between VOC feature data and VOC gas concentration threshold, may include: If the VOC characteristic data is less than or equal to the VOC gas concentration threshold, the first control command is determined to include not requiring the air purification device to operate.

[0070] In this embodiment, if the collected VOC characteristic data are all less than or equal to the VOC gas concentration threshold, the air purification program may not be started. That is, it can be determined that the first control command includes not needing to control the operation of the air purification device.

[0071] Continue to refer to Figure 2 It can determine whether VOC characteristic data exceeds the concentration limit based on preset VOC gas concentration thresholds, that is, to perform the first level of analysis. If all VOC characteristic data are less than the VOC gas concentration threshold (e.g., acetaldehyde concentration ≤ 0.04 mg / m³, formaldehyde concentration ≤ 0.08 mg / m³, toluene concentration ≤ 0.5 mg / m³, TVOC concentration ≤ 2 mg / m³), it can be determined that the first control command includes not needing to control the operation of the air purification device, and the second level of analysis can continue to be performed to perform odor quality analysis of the passenger cabin based on VOC characteristic data and odor characteristic data.

[0072] In some embodiments, the second control command, derived based on VOC feature data and odor feature data, may include: VOC feature data and odor feature data are input into the target neural network model to obtain the second control command output by the target neural network model.

[0073] In this embodiment, VOC feature data can be used to provide basic information about the chemical substances of an odor, and can be used to correlate odors with specific VOC components.

[0074] Odor characteristic data can be used to provide the physical characteristics of the odor itself (such as odor type, intensity, and diffusion) and can be used to distinguish different odor sources (such as carpet smell or leather smell).

[0075] The target neural network model can output a second control command corresponding to the VOC feature data and odor feature data.

[0076] The feature data can be classified using machine learning algorithms (such as support vector machines or deep neural networks) to obtain the odor type corresponding to the odor feature data.

[0077] The types of odors can include carpet smell, genuine leather smell, suede smell, leather smell, plastic smell, glue smell, foam smell, solvent smell, wood smell, rubber smell, sealant smell, smoke smell, food smell, musty smell, and sweat smell, etc.

[0078] It can determine whether the odor characteristic data meets the preset standards (such as "qualified" or "needs purification") based on information such as odor safety threshold and user comfort preferences, and output a second control command.

[0079] The target neural network model is trained using sample VOC feature data and sample odor feature data as samples, and sample control commands corresponding to the sample VOC feature data and sample odor feature data as sample labels.

[0080] During the training phase, a large amount of known odor sample VOC feature data and sample odor feature data (such as acetaldehyde and formaldehyde concentration data and odor feature vector corresponding to "carpet smell") can be collected. The sample VOC feature data and sample odor feature data can be jointly encoded to form a comprehensive feature vector (similar to "odor ID card"). By fusing the chemical information of VOC with the physical features of odor sensors, the model's ability to distinguish odors can be enhanced (such as distinguishing between "leather smell" and "plastic smell", even though the two may contain similar VOC components).

[0081] The model can be trained using supervised learning algorithms to learn the mapping relationship between "comprehensive feature vectors" and "control commands", or other algorithms can be used for training, which is not limited in this application.

[0082] like Figure 2 As shown, when the analysis result corresponding to the odor characteristic data is "inferior to the preset odor quality", the second control command includes the need to control the operation of the air purification device in the vehicle, which can start the air purification program, that is, the air purification device can be controlled to operate.

[0083] If the analysis result corresponding to the odor characteristic data is "better than the preset odor quality", the second control command includes not needing to control the operation of the air purification device, and continuing to monitor VOC gas and odor in the passenger cabin.

[0084] According to the vehicle control method provided in the embodiments of this application, by combining VOC feature data and odor feature data to jointly evaluate the odor quality in the passenger compartment in order to determine the second control command, the misjudgment problem of a single sensor can be solved, the accuracy and precision of odor recognition can be improved, and the precise monitoring and intelligent control of the environmental quality in the passenger compartment can be realized, thereby improving the comfort and safety of the in-vehicle environment.

[0085] In some embodiments, controlling vehicle operation based on at least one of a first control command and a second control command may include: If the first control command includes the need to control the operation of the air purification device in the vehicle, and / or if the second control command includes the need to control the operation of the air purification device in the vehicle, then control the operation of the air purification device in the vehicle.

[0086] In some embodiments, controlling vehicle operation based on at least one of a first control command and a second control command may include: Both the first and second control commands include the steps of acquiring VOC gas data in the passenger compartment collected by the VOC sensor module and odor data in the passenger compartment collected by the odor sensor module, when it is not necessary to control the operation of the air purification device.

[0087] In this embodiment, a "two-level analysis mode" can be used to analyze the air quality in the passenger compartment. For example, VOC gas analysis can be performed first to output a first control command. If it is determined that the first control command includes the need to control the operation of the air purification device, the air purification device in the vehicle can be controlled to operate, and then the detection system can be started.

[0088] If the first control command is determined to include the fact that the operation of the air purification device is not required, odor analysis can be performed based on VOC characteristic data and odor characteristic data to output a second control command. If the second control command is determined to include the fact that the operation of the air purification device is required, the air purification device can be operated. If the second control command is determined to include the fact that the operation of the air purification device is not required, the air quality in the passenger cabin can continue to be monitored.

[0089] In actual implementation, such as Figure 2 As shown, when the user starts the vehicle or remotely starts the air conditioner, the occupant cabin odor recognition and VOC detection system are activated simultaneously, and step S101 is executed. Step S101: The signal processing and data analysis module can extract the feature data of the odor sensor module and the VOC sensor module, output VOC feature data data1 and odor feature data data2, and proceed to step S102. Step S102: The concentration of data1 can be judged to exceed the limit based on the preset VOC gas concentration threshold, that is, the first level analysis is performed. If the VOC concentration recorded in data1 is greater than the preset VOC gas concentration threshold, proceed to step S103; if the VOC concentration recorded in data1 is less than or equal to the preset VOC gas concentration threshold, proceed to step S104.

[0090] Step S103: Send a command to the control output module to start the air purification program.

[0091] Step S104: Input data1 and data2 into the preset target neural network model (odor quality evaluation model), and combine the VOC feature data1 and odor feature data2 to make a comprehensive odor quality judgment, that is, perform the second level analysis. If the odor quality collected by data1 and data2 is worse than the preset standard, then proceed to step S105; if the odor quality collected by data1 and data2 is better than the preset odor quality, then proceed to step S106.

[0092] Step S105: Send a command to the control output module to start the air purification program.

[0093] Step S106: Complete the odor assessment of the crew cabin and restart the detection system.

[0094] In some embodiments, VOC gas detection and odor detection in the passenger compartment can be automatically activated based on vehicle status, air conditioning status, humidity, light intensity, temperature, or user behavior data (such as seat usage and door opening frequency). These can be customized based on user needs, and this application does not impose any limitations.

[0095] Taking the automatic activation of detection based on the vehicle and air conditioning status as an example, step 110 can be further explained.

[0096] In some embodiments, step 110 may include: When the vehicle is running or the air conditioning is on, the system acquires VOC gas data in the passenger compartment collected by the VOC sensor module and odor data in the passenger compartment collected by the odor sensor module based on the target detection cycle.

[0097] In this embodiment, the air quality inside the passenger compartment can be periodically detected based on vehicle startup or remote air conditioning activation.

[0098] The preset time interval corresponding to the target detection cycle can be 4 hours or 5 hours, or it can be other values, which are not limited in this application.

[0099] For example, when the passenger compartment temperature is ≤30℃, the target detection cycle can be set to once every 4 hours; when the passenger compartment temperature is between 30℃ and 40℃, the target detection cycle can be set to once every 2 hours; when the passenger compartment temperature continuously exceeds 40℃ and the static time exceeds 4 hours (such as when the vehicle is parked outdoors for a long time), the system can automatically start the detection system.

[0100] When the user starts the vehicle or remotely starts the air conditioner, the system can automatically trigger the occupant cabin odor recognition and VOC detection cycle. After completing a complete detection cycle (including odor data collection, VOC data collection, data analysis and result determination), the system will enter a waiting state for the preset time interval corresponding to the target detection cycle. When the preset time interval is reached, the system will automatically restart the detection cycle.

[0101] When the user frequently starts the vehicle or the air conditioner, the system can retrieve the log information of the last complete test after each start, such as the start and end times of the test. The test program will then be restarted after a preset time interval from the end of the last complete test.

[0102] According to the vehicle control method provided in the embodiments of this application, by periodically performing odor recognition and VOC detection in the passenger compartment, the waste of computing power and energy caused by excessively frequent detection can be avoided, while ensuring the air quality in the passenger compartment and improving the user experience.

[0103] In some embodiments, step 110 may include: Receive the user's first input; In response to the first input, the VOC gas data in the passenger compartment collected by the VOC sensor module and the odor data in the passenger compartment collected by the odor sensor module are acquired.
