[0033] Embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation of the present application.

[0034] The vehicle control method, computer-readable storage medium, vehicle controller, vehicle control device, and vehicle proposed in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0035] Figure 1 Flowchart of the vehicle control method according to an embodiment of the present application.

[0036] As Figure 1 shown, the vehicle control method according to the embodiment of the present application may include the following steps:

[0037] S1, obtaining the historical driving record and the current position of the vehicle;

[0038] S2, determining the warning threshold according to the historical driving record and the current position;

[0039] S3, obtaining the external humidity and external pressure of the vehicle;

[0040] S4, generating a weather mutation warning when both the change speed of the external humidity and the change speed of the external pressure reach the warning threshold, so as to control the vehicle based on the weather mutation warning.

[0041] Specifically, the historical driving record may be the driving path of the vehicle itself stored in the vehicle, or the historical driving path corresponding to the driver's bound account. For example, when navigating through the vehicle's central control screen, the user's historical records in the navigation app are read to obtain the historical driving record, or it can be obtained through a database or custom-setting, and there is no specific limitation. The current position can be obtained through the vehicle's own positioning device.

[0042] Evaluate the driver's experience value of the current path based on historical driving records and the current location. For example, when the current location does not appear in the historical driving records in the previous month, the initial threshold is used as the preset threshold; when the current location appears in the historical driving records in the previous month, the initial threshold is increased to be used as the preset threshold. Additionally, the increased value of the initial threshold can be further divided based on the occurrence frequency. The higher the occurrence frequency of the current location in the historical driving records closer to the current moment, the richer the driver's experience of the current location, and the greater the increased value of the initial threshold, thereby reducing the warning frequency and power consumption.

[0043] The warning thresholds include the humidity change threshold and the pressure change threshold. The outside humidity of the vehicle is obtained through the humidity sensor configured in the vehicle, and the change speed of the outside humidity is compared with the humidity change threshold. The outside pressure of the vehicle is monitored through the pressure sensor configured in the vehicle, and the change speed of the outside pressure is compared with the pressure change threshold. When the change speed of the outside humidity is greater than or equal to the humidity change threshold and the change speed of the outside pressure is greater than or equal to the pressure change threshold, it is confirmed that the change speeds of both the outside humidity and the outside pressure reach the warning thresholds, and it is considered that the humidity and pressure of the outside environment change sharply, and the current driver's driving experience is difficult to cope with this weather change in a timely manner. At this time, a weather mutation warning is generated to remind the driver based on the weather mutation warning, and at the same time, the vehicle is controlled according to the weather mutation warning. Among them, the weather mutation warning can include reminding the vehicle owner of the arrival of bad weather (heavy rain, heavy snow, strong wind, etc.) through warning lights and voice reminders. Based on the weather mutation warning by the user, a vehicle control signal can also be generated synchronously to control the vehicle, such as a speed limit signal to limit the maximum speed of the vehicle, and the various modules in the vehicle are controlled to make corresponding actions through the changing environmental information to improve driving comfort.

[0044] This embodiment can detect environmental changes in a timely manner by monitoring the outside humidity and the outside pressure of the vehicle, discover problems that are difficult for the driver to detect, and thus issue warnings and make adjustments in a timely manner. Additionally, the warning timing is generated based on the driver's driving experience at this location. For example, when the driver has rich experience at this place, the warning can be postponed to reduce energy consumption on the premise of ensuring driving safety; when the driver has no driving experience or less experience in this area, the warning can be advanced to ensure driving safety.

[0045] In an embodiment of the present application, determining a warning threshold according to historical driving records and the current location includes: when the historical driving records include the driving records corresponding to the current location and the number of records is greater than or equal to a preset number, determining the warning threshold as the first warning threshold; when the historical driving records do not include the driving records corresponding to the current location, or when the historical driving records include the driving records corresponding to the current location and the number of records is less than the preset number, determining the warning threshold as the second warning threshold, where the second warning threshold is less than the first warning threshold.

[0046] That is to say, the driving experience of the driver is evaluated according to the number of historical driving records corresponding to the current location. When the number of historical driving records is greater than or equal to the preset number, it is determined that the driving experience at this location is rich, and the larger first warning threshold is selected as the warning threshold. When there is no historical driving record corresponding to the current location, or when the number of historical driving records is less than the preset number, it is determined that the driving experience at this location is lacking, and the smaller second warning threshold is selected, so as to achieve timely warning and improve driving safety.

[0047] In addition, to ensure that the historical driving records have high reference value, the historical driving records can be screened by data such as the time interval from the current moment and the driver binding information.

[0048] In addition to the above embodiments, other external vehicle environment data can also be collected. By combining multiple types of environment data for environment data analysis, corresponding instructions are sent to the vehicle machine according to the data analysis results, and corresponding actions are taken according to the instructions to improve the vehicle control accuracy. The vehicle control strategy further combined with the external vehicle temperature will be described in detail below.

[0049] In an embodiment of the present application, the vehicle control method further includes: obtaining the external vehicle temperature; determining an icing coefficient according to the external vehicle temperature and the external vehicle humidity; obtaining the braking ability of the vehicle; determining the maximum speed limit of the vehicle according to the icing coefficient and the braking ability.

[0050] Specifically, in the autumn and winter seasons in some mountainous areas, there is an obvious temperature difference between the foot of the mountain and the mountainside. The weather forecast is rain in the local area, while it may be rain and snow in the mountainous area. Problems such as road icing are dangerous that drivers are difficult to predict.

[0051] To improve driving safety, the external vehicle temperature is further obtained. When the external vehicle temperature reaches the icing temperature and the external vehicle humidity is high, it is considered that the possibility of icing is relatively large. Therefore, a preset relationship between the external vehicle temperature - external vehicle humidity - icing coefficient can be preset in advance, and then the icing coefficient is determined based on the actually obtained external vehicle temperature and external vehicle humidity. The icing coefficient is used to characterize the icing possibility of the current external vehicle environment.

[0052] Then, the maximum speed limit of the vehicle is determined by combining the braking ability of the vehicle and the possibility of icing. It can be understood that the stronger the braking ability of the vehicle, the greater the corresponding maximum speed limit; the weaker the braking ability of the vehicle, the smaller the corresponding maximum speed limit. Taking the example that the larger the icing coefficient, the greater the possibility of icing in the current external environment of the vehicle; the smaller the icing coefficient, the smaller the possibility of icing in the current external environment of the vehicle, then, the larger the icing coefficient, the smaller the maximum speed limit; the smaller the icing coefficient, the larger the maximum speed limit. Thus, the maximum speed limit of the vehicle is determined by combining the braking ability and the icing coefficient, so as to perform speed limit control on the vehicle and improve the running safety of the vehicle. For example, a mapping table between braking ability - icing coefficient - maximum speed limit can be preset in advance, and the maximum speed limit can be obtained by looking up the table during application, or the corresponding fitting function can be determined through experiments, and the maximum speed limit can be obtained through function calculation.

[0053] Furthermore, when determining that the vehicle is driving in rainy or snowy weather, the external temperature, external humidity, and external pressure of the vehicle can be combined to generate a voice safety reminder, and the driver can be actively reminded to slow down and pay attention to driving safety through the in-vehicle voice system. After receiving the reminder, the driver can reduce the vehicle speed to avoid accidents caused by the vehicle getting out of control due to too high a vehicle speed, thereby improving driving safety.

[0054] In an embodiment of the present application, the vehicle control method further includes: in response to a parking unlock instruction, obtaining the current external temperature of the vehicle and the initial external temperature of the vehicle when it starts; when the temperature difference between the current external temperature and the initial external temperature exceeds a preset temperature threshold, generating a dressing reminder signal based on the interval where the current external temperature is located.

[0055] Specifically, when driving long distances or in mountainous areas, the temperature difference between the possible getting-off point and the getting-on point may be relatively large. If the user does not change clothes in time when getting off the vehicle, it will cause great physical discomfort. For this reason, in this embodiment, when the door unlocks during parking, it is considered that a passenger is getting off the vehicle. At this time, if the temperature difference between the current temperature of the vehicle and the initial external temperature of the vehicle when it starts is small, it is considered that the clothing worn by the user when getting on the vehicle is suitable for the temperature at the getting-off point, and no voice reminder is given; if the temperature difference between the current temperature of the vehicle and the initial external temperature of the vehicle when it starts is large, it is considered that the clothing worn by the user when getting on the vehicle is not suitable for the temperature at the getting-off point, and different clothing is further reminded according to the interval where the external temperature is located to improve user comfort.

[0056] The preset temperature threshold can be set according to the actual situation. For example, the preset temperature threshold can be directly set according to the physical sensation requirements of the user population aged 20 - 30; or through user information collection, the age and gender of the current passenger are estimated, and then the corresponding preset temperature threshold is determined according to the passenger's age and gender to achieve adaptive adjustment and improve the riding comfort.

[0057] In an embodiment of the present application, the vehicle control method further includes: when the outside temperature of the vehicle exceeds a preset temperature threshold, acquiring the vehicle's circumferential image information; when it is determined that there is an open fire according to the circumferential image information, sending an alarm signal to a first target terminal, where the alarm signal includes the current position; when it is determined that there is no open fire according to the circumferential image information, sending a high-temperature warning signal to a second target terminal. The preset temperature threshold can be set according to the actual situation.

[0058] Specifically, when the temperature detection module detects that the outside temperature of the vehicle exceeds the preset temperature threshold, it is considered that the outside environmental temperature is abnormal. The vehicle's other detection units such as cameras are called to acquire the circumferential image of the vehicle to determine whether there is an open fire. Once an open fire is confirmed, an emergency alarm is immediately sent to the driver's mobile phone through the cloud. At the same time, the 119 alarm for the fire and the address are sent to minimize the loss at the fastest speed. If there is no open fire, a high-temperature warning signal is sent to the user terminal to timely inform the driver to reduce property losses and ensure user safety.

[0059] In an embodiment of the present application, the vehicle control method further includes: acquiring the vehicle's interior environment information and the outside temperature; determining a target control instruction according to one or more of the outside humidity, outside pressure, interior environment information, and outside temperature to control the vehicle's auxiliary function device.

[0060] Specifically, the interior environment information may include the interior humidity, interior temperature, etc., without specific limitation. For example, in addition to giving dressing reminders according to the range of the outside temperature, the on-vehicle air conditioner can also be controlled for sudden temperature drops (such as entering the snow line from south to north, etc.) to perform operations such as heating, cooling, defogging, and defrosting to improve user comfort. In extremely hot weather in summer, many drivers expose their cars in direct sunlight for a long time. At this time, high-temperature warnings can be given through interior temperature detection to avoid shortening the service life of the car caused by high temperature, and even prevent accidents such as car spontaneous combustion in some extreme cases. In addition, other environmental parameters inside the vehicle can also be detected, and operation suggestions can be given based on the current environmental conditions determined by further combining the outside temperature, outside pressure, and outside humidity, such as related operations such as interior temperature control and window opening and closing, so as to eliminate risks outside the vehicle and provide a comfortable environment inside the vehicle.

[0061] The purpose of this embodiment is to timely detect changes in data such as the temperature, humidity, and air pressure of the interior and exterior environments of the vehicle through two environmental detection modules inside and outside the vehicle, and then give timely feedback and reminders to the driver through data collection and analysis.

[0062] For example, a driver is driving a car from the foot of a mountain onto a mountain road. As the altitude decreases, the temperature drops significantly. The vehicle's environmental detection module will detect the change in the outside temperature, collect and analyze the data, and send it to the central processing unit. After final analysis, the audio output module will issue a warning to remind the driver to close the windows, turn on the air conditioner, slow down, etc. Subsequently, as the vehicle continues to move forward and the altitude keeps rising, the temperature begins to drop below freezing point and the road surface becomes icy. The central processing unit will combine the environmental data and feedback data such as the vehicle braking effect, issue a warning and limit the maximum speed of the vehicle.

[0063] Moreover, the popularity of urban cars is very high nowadays, and the vehicles parked in various parking lots are extremely dense. In such a high-density parking area, the chain losses caused by a fire would be incalculable. The vehicle's temperature detection module can play a very good warning role. When a fire breaks out, the temperature detection module will detect the abnormal environmental temperature and report it to the central processing unit in a timely manner. The central processing unit can call all other detection systems to confirm whether there is an open fire. Once confirmed, it will immediately send an emergency alarm to the driver's mobile phone through the cloud, and at the same time complete the 119 alarm for the fire and send the address, so as to minimize the loss at the fastest speed.

[0064] The above are the application scenarios for extreme environments. During daily use, it can also provide a more comfortable and safe driving experience for drivers. For example, before the vehicle departs, it can verify the weather conditions according to the changes in humidity and temperature to remind the driver of clothing choices and carrying an umbrella, etc. In the hot summer days, when the car is under strong sunlight, the temperature inside the car will quickly reach a level that endangers the in-vehicle components. At this time, it can monitor the change in the temperature inside the car in real time and timely remind the driver to cover the sunshade cloth to reduce the damage to the vehicle in hot weather. On the contrary, in winter, when a person drives in the car for a long time, the humidity inside the car will increase significantly, which will condense water mist on the window and obstruct the driving vision. In the past actual scenarios, this phenomenon would go through a process of affecting occurrence and then being processed, which would affect driving safety. At this time, this method can detect in a timely manner the factors such as the decrease in the outside temperature and the increase in the humidity inside the car that will cause water mist condensation, so as to take countermeasures before the problem occurs and reduce potential safety hazards.

[0065] Thus, this method provides assistance to the driver through environmental detection, acting like a navigator during driving. Especially when first driving into areas that are difficult to access in daily life, such as plateaus, deserts, high-latitude winter areas, etc., since most drivers lack driving experience in such areas, they will seem caught off guard when some problems occur. And this method can comprehensively consider environmental factors such as temperature, air pressure, wind speed, humidity, etc., remind the driver to take measures in advance and how to take measures, which can give great help to the driver. In many cases, this can even avoid accidents.

[0066] Therefore, the vehicle control method at least includes the following technical effects:

[0067] (1) Improve driving comfort: When it is detected that there are obvious changes in the vehicle's external environment, the various modules inside the vehicle are controlled to make corresponding actions according to the changed environmental information to ensure driving comfort.

[0068] (2) Improve customer safety: When it is detected that the temperature of the vehicle's surrounding environment is too high, the abnormality of the environmental temperature will be reported to the central processor in a timely manner, and the driver will be informed in a timely manner to reduce property losses and ensure user safety.

[0069] (3) Improve driving safety: When it is detected that the vehicle is driving in rainy or snowy weather, the in-vehicle voice system will actively remind the driver to slow down and pay attention to driving safety. After receiving the reminder, the driver can reduce the vehicle speed to avoid accidents caused by the vehicle getting out of control due to too high a vehicle speed, thereby improving driving safety.

[0070] As a specific embodiment of the present application, as Figure 2 shown, the vehicle control method may include the following steps:

[0071] S101, Obtain the historical driving record and the current position of the vehicle.

[0072] S102, Determine whether the historical driving record includes the driving record corresponding to the current position. If so, execute step S103; if not, execute step S105.

[0073] S103, Determine whether the number of records is greater than or equal to the preset number. If so, execute step S104; if not, execute step S105.

[0074] S104, Determine that the warning threshold is the first warning threshold.

[0075] S105, Determine that the warning threshold is the second warning threshold.

[0076] S106, Obtain the external humidity and external pressure of the vehicle.

[0077] S107, Determine whether the change speed of the external humidity and the change speed of the external pressure both reach the warning threshold. If so, execute step S108; if not, execute step S106.

[0078] S108, Generate a weather mutation warning and control the vehicle based on the weather mutation warning.

[0079] In summary, according to the vehicle control method of the embodiments of the present application, first, obtain the historical driving record and the current position of the vehicle, determine the warning threshold according to the historical driving record and the current position. During the driving process of the vehicle, obtain the external humidity and external pressure of the vehicle. When the change speed of the external humidity and the change speed of the external pressure both reach the warning threshold, generate a weather mutation warning to control the vehicle based on the weather mutation warning. Thus, this method evaluates the driver's experience value for the current driving path according to the historical driving record and the current position, promptly detects environmental changes according to the external humidity and external pressure, discovers environmental problems that are difficult for the driver to detect with the naked eye, and combines the user experience to achieve timely warning of the driver, adjust the vehicle driving control strategy, and improve driving safety.

[0080] Corresponding to the above embodiments, the present application also proposes a computer-readable storage medium.

[0081] The computer-readable storage medium of the embodiments of the present application stores a vehicle control program thereon. When the vehicle control program is executed by a processor, the above vehicle control method is implemented.

[0082] According to the computer-readable storage medium of the embodiments of the present application, when the vehicle control program stored thereon is executed by a processor, the above vehicle control method is implemented. Based on the above vehicle control method, environmental problems that are difficult for the driver to detect with the naked eye are discovered, and the user experience is combined to achieve timely warning of the driver, adjust the vehicle driving control strategy, and improve driving safety.

[0083] Corresponding to the above embodiments, the present application also proposes a vehicle controller.

[0084] As Figure 3 shown, the vehicle controller 100 of the embodiments of the present application includes a memory 110, a processor 120, and a vehicle control program stored on the memory 110 and executable on the processor 120. When the processor 120 executes the vehicle control program, the above vehicle control method is implemented.

[0085] According to the vehicle controller of the embodiments of the present application, when the processor executes the vehicle control program, the above vehicle control method is implemented. Based on the above vehicle control method, environmental problems that are difficult for the driver to detect with the naked eye are discovered, and the user experience is combined to achieve timely warning of the driver, adjust the vehicle driving control strategy, and improve driving safety.

[0086] Corresponding to the above embodiments, the present application also proposes a vehicle control device.

[0087] As Figure 4 shown, the vehicle control device of the embodiments of the present application includes: a first acquisition module 10, a determination module 20, a second acquisition module 30, and a control module 40.

[0088] Among them, the first acquisition module 10 is used to acquire the historical driving record and the current position of the vehicle. The determination module is used to determine the warning threshold according to the historical driving record and the current position. The second acquisition module 20 is used to acquire the outdoor humidity and the outdoor pressure of the vehicle. The control module 30 is used to generate a weather mutation warning when both the change speed of the outdoor humidity and the change speed of the outdoor pressure reach the warning threshold, so as to control the vehicle based on the weather mutation warning.

[0089] According to an embodiment of the present application, the determination module 20 determines the warning threshold according to the historical driving record and the current position, specifically: when the historical driving record includes the driving record corresponding to the current position and the number of records is greater than or equal to the preset number, determining the warning threshold as the first warning threshold; when the historical driving record does not include the driving record corresponding to the current position, or the historical driving record includes the driving record corresponding to the current position and the number of records is less than the preset number, determining the warning threshold as the second warning threshold, where the second warning threshold is less than the first warning threshold.
