[0033] Embodiments of the present application are described in detail below with reference to the accompanying drawings, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0034] A vehicle control method, a computer readable storage medium, a vehicle controller, a vehicle control device and a vehicle according to embodiments of the present application are described below with reference to the accompanying drawings.

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

[0036] As shown in Figure 1 The vehicle control method according to an embodiment of the present application can include the following steps:

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

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

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

[0040] S4, generating a weather mutation warning in a case where a change speed of the outside humidity and a change speed of the outside pressure both reach the warning threshold, to control the vehicle based on the weather mutation warning.

[0041] Specifically, the historical driving record can be a driving path of the vehicle itself, or a historical driving path corresponding to a driver's bound account can be obtained, for example, when navigation is performed through a central control screen of the vehicle, a user historical record in a navigation app is read to obtain the historical driving record, or the historical driving record can be obtained through a database or customized setting, which is not limited. The current position can be obtained through a positioning device of the vehicle.

[0042] The experience value of the driver to the current path is evaluated according to the historical driving record and the current position. For example, when the current position does not appear in the historical driving record in the previous month, an initial threshold value is used as the preset threshold value; when the current position appears in the historical driving record in the previous month, the initial threshold value is increased to be used as the preset threshold value, and the initial threshold value can be further divided based on the frequency of appearance. The higher the frequency of appearance of the current position in the historical driving record close to the current time, the more experience the driver has for the current position, and the greater the increased value of the initial threshold value, thereby reducing the warning frequency and reducing power consumption.

[0043] The warning threshold value includes a humidity change threshold value and a pressure change threshold value. The humidity outside the vehicle is obtained by the humidity sensor configured on the vehicle, and the change speed of the humidity outside the vehicle is compared with the humidity change threshold value. The pressure outside the vehicle is monitored by the pressure sensor configured on the vehicle, and the change speed of the pressure outside the vehicle is compared with the pressure change threshold value. When the change speed of the humidity outside the vehicle is greater than or equal to the humidity change threshold value and the change speed of the pressure outside the vehicle is greater than or equal to the pressure change threshold value, it is confirmed that the change speed of the humidity outside the vehicle and the change speed of the pressure outside the vehicle both reach the warning threshold value, it is considered that the humidity and the pressure of the environment outside the vehicle change sharply, and the driving experience of the current driver is difficult to cope with the weather change. At this time, a weather mutation warning is generated to remind the driver based on the weather mutation warning, and the vehicle is controlled according to the weather mutation warning. The weather mutation warning can include warning the arrival of bad weather (heavy rain, heavy snow, strong wind, etc.) through warning lights and voice reminders, controlling the vehicle based on the weather mutation warning, and synchronously generating a vehicle control signal to control the vehicle, such as a speed limit signal to limit the maximum speed of the vehicle, controlling the modules in the vehicle to make corresponding actions through changing environmental information, and improving driving comfort.

[0044] The embodiment can timely perceive environmental changes and find problems that the driver cannot find by monitoring the humidity and pressure outside the vehicle, thereby timely issuing a warning and making adjustments. In addition, the warning timing is generated based on the driving experience of the user for the position. For example, the warning can be postponed when the driver has rich experience for the position, to reduce energy consumption on the premise of ensuring driving safety; the warning can be advanced when the driver has no driving experience for the region or has less experience, to ensure driving safety.

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

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

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

[0048] In addition to the above embodiments, other off-vehicle environment data can also be collected, and the vehicle control precision is improved by combining multiple types of environment data for environment data analysis, and issuing corresponding instructions to the vehicle according to the data analysis result, and performing corresponding actions according to the instructions.

[0049] In an embodiment of the present application, the vehicle control method further comprises: obtaining the off-vehicle temperature of the vehicle; determining the icing coefficient according to the off-vehicle temperature and the off-vehicle humidity; obtaining the braking capability of the vehicle; and determining the highest limit speed of the vehicle according to the icing coefficient and the braking capability.

[0050] Specifically, in the autumn and winter seasons in some mountainous areas, there is a significant temperature difference between the foot of the mountain and the waist of the mountain. The weather report is rain weather in the local area, but it may be snow weather in the mountainous area. The icing of the road surface and other problems may be unpredictable dangers for the driver.

[0051] In order to improve the driving safety, the off-vehicle temperature is further obtained, when the off-vehicle temperature reaches the icing temperature and the off-vehicle humidity is high, it is considered that there is a high possibility of icing. Therefore, a preset relationship between the off-vehicle temperature, the off-vehicle humidity and the icing coefficient can be set in advance, and then the icing coefficient is determined based on the actually obtained off-vehicle temperature and off-vehicle humidity. The icing coefficient is used to represent the icing possibility of the current off-vehicle environment.

[0052] Then the highest limit speed of the vehicle is determined in combination with the braking ability of the vehicle and the icing possibility, and it can be understood that the stronger the braking ability of the vehicle is, the greater the corresponding highest limit speed is; the weaker the braking ability of the vehicle is, the smaller the corresponding highest limit speed is. For example, the greater the icing coefficient is, the greater the icing possibility of the current vehicle external environment is; the smaller the icing coefficient is, the smaller the icing possibility of the current vehicle external environment is. Then, the greater the icing coefficient is, the smaller the highest limit speed is; the smaller the icing coefficient is, the greater the highest limit speed is. Thus, the highest limit speed of the vehicle is determined in combination with the braking ability and the icing coefficient, so that the speed of the vehicle is controlled, and the running safety of the vehicle is improved. For example, a mapping table among the braking ability, the icing coefficient and the highest limit speed can be pre-set, the highest limit speed is obtained by table lookup in the application process, or the corresponding fitting function can be determined through test, and the highest limit speed is obtained by function calculation.

[0053] Further, in combination with the vehicle external temperature, the vehicle external humidity and the vehicle external pressure, when the vehicle drives in rainy or snowy days, a voice safety reminder can be generated, the driver is actively reminded to slow down and pay attention to driving safety through the in-vehicle voice system, the driver can reduce the vehicle speed after receiving the reminder, so that accidents caused by too fast vehicle speed are avoided, and the driving safety is improved.

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

[0055] Specifically, when long-distance driving or driving in mountainous areas, the temperature difference between the getting-off point and the getting-on point can be large, and if the user does not timely change clothes when getting off, a large physical discomfort can be caused. Therefore, when the vehicle door unlocking action occurs, it is considered that a passenger gets off, and at this time, if the temperature difference between the current temperature of the vehicle and the initial vehicle external temperature when the vehicle starts is small, it is considered that the dressing of the user when getting on is suitable for the temperature of the getting-off point, and no voice reminder is performed; if the temperature difference between the current temperature of the vehicle and the initial vehicle external temperature when the vehicle starts is large, it is considered that the dressing of the user when getting on has already been suitable for the temperature of the getting-off point, and different dressings are reminded according to the interval in which the vehicle external temperature is located, so as to improve the user comfort.

[0056] The preset temperature threshold can be set according to actual conditions, for example, the preset temperature threshold is set directly according to the body feeling demand of the user group of 20-30 age stage; or the age and gender of the current passenger are estimated through user information collection, and then the corresponding preset temperature threshold is determined according to the passenger age and gender, so as to realize adaptive adjustment and improve the riding comfort.

[0057] In an embodiment of the present application, the vehicle control method further comprises: obtaining vehicle ambient image information when the vehicle external temperature exceeds a preset temperature threshold; sending an alarm signal to the first target terminal when it is determined from the vehicle ambient image information that there is an open flame, wherein the alarm signal comprises the current position; and sending a high-temperature early warning signal to the second target terminal when it is determined from the vehicle ambient image information that there is no open flame. The preset temperature threshold can be set according to actual conditions.

[0058] Specifically, when the temperature detection module detects that the vehicle external temperature exceeds the preset temperature threshold, it is considered that the vehicle external environment temperature is abnormal, and the vehicle ambient image is obtained by calling other detection units of the vehicle such as a camera to determine whether there is an open flame. Once it is confirmed that there is an open flame, an emergency alarm is immediately sent to the driver's mobile phone through the cloud, and the 119 fire alarm and address sending are completed at the same time, so as to minimize the loss at the fastest speed. If there is no open flame, a high-temperature early warning signal is sent to the user terminal to timely inform the driver to reduce property loss and protect the safety of the user.

[0059] In an embodiment of the present application, the vehicle control method further comprises: obtaining vehicle ambient image information and vehicle external temperature; determining a target control instruction according to one or more of the vehicle external humidity, the vehicle external pressure, the vehicle internal environment information and the vehicle external temperature, to control the auxiliary function device of the vehicle.

[0060] Specifically, the vehicle internal environment information can include vehicle internal humidity, vehicle internal temperature, etc., and is not specifically limited. For example, in addition to the wearing reminder according to the interval of the vehicle external temperature, the vehicle air conditioner can be controlled for heating, cooling, defogging and defrosting, etc. to improve user comfort in the event of sudden temperature drop (such as entering the snow line from south to north, etc.). In the extremely hot weather of summer, many drivers expose the car to direct sunlight for a long time. At this time, a high-temperature early warning can be given through the vehicle internal temperature detection to avoid the shortening of the service life of the car caused by high temperature, and even cause the car to catch fire in some extreme cases. In addition, other environmental parameters in the vehicle can be detected, and operation suggestions such as vehicle internal temperature control, vehicle window opening and closing, etc. are given according to the current environmental conditions determined by combining the vehicle external temperature, the vehicle external pressure and the vehicle external humidity, 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 discover the changes of temperature, humidity and air pressure data of the vehicle internal and external environment through the vehicle internal and external environment detection modules, and give timely feedback and reminders to the driver after data collection and analysis.

[0062] For example, the driver is driving on a mountain road from the foot of the mountain. As the height decreases, the temperature drops significantly. The environmental detection module of the car will find the change of the outside temperature, collect and analyze the data and send it to the central processor. After the final analysis, the audio output module will issue a warning, reminding the driver to close the window, turn on the air conditioner, slow down, etc. As the vehicle continues to travel, the height continues to rise, and the temperature begins to drop below freezing, causing the road to freeze. The central processor will combine environmental data and feedback data such as car braking effect to issue a warning and limit the maximum speed of the car.

[0063] Moreover, the popularity of urban cars is very high today, and the parking of various parking lots is extremely dense. In such a high-density parking area, the chain loss caused by a fire will be incalculable. The temperature detection module of the vehicle can play a good warning role. When a fire occurs, the temperature detection module detects the abnormality of the environmental temperature and reports it to the central processor in a timely manner. The central processor 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 complete the 119 alarm and address sending of the fire, so as to minimize the loss at the fastest speed.

[0064] The above is the application scenario of extreme environment. In daily use, it can also provide a more comfortable and safe driving experience for the driver. For example, before the vehicle departs, the weather can be verified according to the humidity and temperature changes to remind the driver to choose and carry an umbrella, etc. In the hot summer weather, the car is under strong sunlight, and the temperature in the car will soon reach a temperature that is harmful to the car's components. At this time, the change of the temperature in the car can be monitored in real time, and the driver can be reminded to cover the sunshade cloth in time to reduce the damage of the hot weather to the vehicle. Conversely, in winter, the humidity in the car will increase significantly, causing water mist to condense on the car window and hinder the driver's view. In the past, this phenomenon would go through a process of influence and processing, which would affect driving safety. At this time, the method can detect factors such as a decrease in outside temperature and an increase in humidity in the car that can cause water mist condensation, so that measures can be taken before the problem occurs, reducing safety hazards.

[0065] Therefore, the method assists the driver through environmental detection, which is equivalent to a navigator during driving. Especially when driving in areas that are difficult to access in daily life, such as highlands, deserts, high-latitude winter areas, etc., since the driver mostly lacks experience in driving in such areas, they will be caught off guard when some problems occur. The method can combine temperature, air pressure, wind speed, humidity, and other environmental factors to remind the driver to take measures in advance and how to take measures, which can greatly help the driver. In many cases, this can even prevent accidents from occurring.

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

[0067] (1) Improve the comfort of driving: when the outside environment of the vehicle is detected to change significantly, the inside modules of the vehicle are controlled to make corresponding actions according to the changed environment information, to ensure the driving comfort.

[0068] (2) Improve the safety of customers: when the ambient temperature of the vehicle is detected to be too high, the abnormality of the ambient temperature will be reported to the central processor in time, to inform the driver in time to reduce the property loss and protect the user safety.

[0069] (3) Improve the safety of driving: when the vehicle is detected to drive in rainy or snowy days, the voice system in the vehicle actively reminds the driver to reduce the speed and pay attention to the driving safety. After receiving the reminder, the driver can reduce the speed of the vehicle to avoid accidents caused by the vehicle out of control due to the too fast speed, to improve the safety of driving.

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

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

[0072] S102, whether the historical driving record includes the driving record corresponding to the current position. If yes, execute step S103; if no, execute step S105.

[0073] S103, determine whether the number of records is greater than or equal to the preset number. If yes, execute step S104; if no, execute step S105.

[0074] S104, determine the warning threshold as the first warning threshold.

[0075] S105, determine the warning threshold as the second warning threshold.

[0076] S106, obtain the outside humidity and the outside pressure of the vehicle.

[0077] S107, determine whether the change speed of the outside humidity and the change speed of the outside pressure both reach the warning threshold. If yes, execute step S108; if no, 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 embodiment of the present application, firstly, the historical driving record and the current position of the vehicle are acquired, the early warning threshold is determined according to the historical driving record and the current position, the outside humidity and the outside pressure of the vehicle are acquired during the driving of the vehicle, and the weather mutation early warning is generated in the case that the change speed of the outside humidity and the change speed of the outside pressure both reach the early warning threshold, so as to control the vehicle based on the weather mutation early warning. Thus, the method evaluates the experience value of the driver on the current driving path according to the historical driving record and the current position, timely perceives the environmental change according to the outside humidity and the outside pressure, finds the environmental problem that is difficult for the driver to find with naked eyes, and realizes the timely early warning of the driver and the adjustment of the vehicle driving control strategy in combination with the user experience, thereby improving the driving safety.
