Technical Field

[0001] This application relates to the field of vehicle control, and more specifically, to a control method, device, and vehicle for preventing vehicle frosting in the field of vehicle control. Background Art

[0002] A vehicle parked stationary in cold and humid weather is at risk of frosting. When the temperature difference between the inside and outside of the vehicle and the humidity outside the vehicle meet the frosting conditions, frosting will occur on the vehicle. After the vehicle frosts, it takes the user's time to defrost; if not defrosted, it may pose a threat to the user's driving safety.

[0003] Therefore, how to prevent vehicle frosting in a timely manner is an urgent problem to be solved to ensure driving safety. Summary of the Invention

[0004] This application provides a control method, device, and vehicle for preventing vehicle frosting, and this method can prevent vehicle frosting in a timely manner.

[0005] In a first aspect, a control method for preventing vehicle frosting is provided. The method includes: obtaining weather state information of the vehicle location where the vehicle is located; in the case where the weather state information indicates that the vehicle has a frosting risk, sending a reminder message for moving the vehicle to a terminal associated with the vehicle; in the case where a confirmation message for the reminder message for moving the vehicle is not received, controlling to turn on a target sensor to collect the vehicle's interior temperature, exterior temperature, and exterior humidity, and the target sensor includes at least a temperature sensor and a humidity sensor; in the case where the temperature difference between the interior temperature and the exterior temperature and the exterior humidity meet the condensation conditions, controlling to execute a target anti-frosting strategy to reduce the temperature difference between the inside and outside of the vehicle.

[0006] In the above technical solution, this embodiment provides a control method for preventing vehicle frosting: obtaining weather state information of the vehicle location, which is used to determine whether the vehicle has a frosting risk. If the weather state information indicates that the vehicle has a frosting risk, a reminder message for moving the vehicle is sent to the associated terminal; in the case where a confirmation message for the reminder message for moving the vehicle is not received, controlling to turn on the target sensor to collect the vehicle's interior temperature, interior temperature, and exterior humidity. When the temperature difference and the exterior humidity meet the condensation conditions, it indicates that the vehicle is more likely to frost, and then automatically control to execute the target anti-frosting strategy to avoid vehicle frosting, eliminate driving hazards, and also save the user's time for defrosting before using the vehicle; in addition, only in the case where a confirmation message for the reminder message for moving the vehicle is not received, controlling to turn on the target sensor for frosting detection can avoid wasting the vehicle's power consumption by turning on the target sensor in real time, and improve the timeliness and accuracy of judging the vehicle's frosting risk.

[0007] In combination with the first aspect, in some possible implementation manners, when the confirmation information for the vehicle relocation reminder message is not received, controlling to turn on the target sensor to collect the in-vehicle temperature, the out-vehicle temperature, and the out-vehicle humidity, including: when the confirmation information for the vehicle relocation reminder message is not received, sending policy enabling information to the terminal associated with the vehicle, where the policy enabling information is used to confirm whether to execute the anti-frosting policy; when the confirmation information for the policy enabling information is received, controlling to turn on the target sensor to collect the in-vehicle temperature, the out-vehicle temperature, and the out-vehicle humidity.

[0008] In the above technical solution, the present application also proposes that if the confirmation information from the user for the vehicle relocation reminder message is not received, indicating that the user may use the vehicle in the near future and there is no need to relocate the vehicle, then sending policy enabling information to the terminal associated with the vehicle to confirm whether the vehicle needs to execute the anti-frosting policy. When the confirmation information for the policy enabling information is received, controlling to turn on the target sensor to collect the in-vehicle temperature, the out-vehicle temperature, and the out-vehicle humidity; when the user chooses not to relocate the vehicle, sending the policy enabling information to the terminal again, and the user independently decides whether to execute the anti-frosting policy, making the anti-frosting process more flexible and more in line with the actual needs of the user.

[0009] In combination with the first aspect and the above implementation manners, in some possible implementation manners, the policy enabling information further includes at least two candidate anti-frosting policies; when the temperature difference between the in-vehicle temperature and the out-vehicle temperature and the out-vehicle humidity meet the condensation condition, controlling to execute the target anti-frosting policy, including: when the temperature difference between the in-vehicle temperature and the out-vehicle temperature and the out-vehicle humidity meet the condensation condition, based on the confirmation information for the policy enabling information, determining the target anti-frosting policy among the candidate anti-frosting policies that need to be enabled; controlling to execute the target anti-frosting policy.

[0010] In the above technical solution, the present application also proposes that the policy enabling information further includes at least two candidate anti-frosting policies for the user to select the target anti-frosting policy to be adopted; when the temperature difference between the in-vehicle temperature and the out-vehicle temperature and the out-vehicle humidity both meet the condensation condition, based on the confirmation information from the user for the policy enabling information, determining the target anti-frosting policy among the candidate anti-frosting policies that need to be enabled, and controlling the vehicle to execute the above target anti-frosting policy. The user can select the target anti-frosting policy according to the current needs to achieve the purpose of anti-frosting while selecting a suitable target anti-frosting policy.

[0011] Combined with the first aspect and the above implementation manners, in some possible implementation manners, when the weather condition information indicates that there is a risk of vehicle frosting, a parking reminder message is sent to the terminal associated with the vehicle, including: when the weather condition information indicates that there is a risk of vehicle frosting, detecting whether the vehicle is in an open-air scenario; when the vehicle is in an open-air scenario, sending a parking reminder message to the terminal associated with the vehicle.

[0012] In the above technical solution, the present application also proposes to detect whether the vehicle is in an open-air scenario when the weather condition information indicates that there is a risk of vehicle frosting, so as to more accurately determine whether the weather condition information will have an adverse impact on the vehicle. If the vehicle is in an open-air scenario, it indicates that the weather condition information will have an impact on the vehicle, resulting in vehicle frosting. A parking reminder message is sent to the terminal associated with the vehicle to remind the user that the vehicle can be parked in a non-open-air scenario to prevent vehicle frosting. If the vehicle is in a non-open-air scenario, it indicates that the weather condition information will not cause vehicle frosting, and there is no need to send a parking reminder message to the terminal, making the sending of the parking reminder message more in line with the actual situation and avoiding sending invalid reminders to the user.

[0013] Combined with the first aspect and the above implementation manners, in some possible implementation manners, the method further includes: when receiving a confirmation message for the parking reminder message, detecting whether a parking operation is received within a target time period; when no parking operation is detected, controlling the activation of a target sensor to collect the vehicle's interior temperature, exterior temperature, and exterior humidity; when the temperature difference between the interior temperature and the exterior temperature and the exterior humidity meet the condensation condition, controlling the execution of a target anti-frosting strategy.

[0014] In the above technical solution, considering that when the time period between receiving the confirmation message for the parking reminder message and receiving the user's parking operation is relatively long, the vehicle may have frosted. The present application also proposes to detect whether a parking operation by the user is received within a target time period after receiving the confirmation message for the parking reminder message; if no parking operation is received, controlling the activation of the target sensor to collect the vehicle's interior temperature, exterior temperature, and exterior humidity, and when the temperature difference between the interior temperature and the exterior temperature and the exterior humidity meet the condensation condition, controlling the vehicle to execute a target anti-frosting strategy. When the user confirms parking but does not perform a parking operation within the target time period, automatically controlling the activation of the target sensor to detect the interior temperature, exterior temperature, and exterior humidity of the vehicle, and when the temperature difference and the exterior humidity meet the condensation condition, controlling the execution of the target anti-frosting strategy.

[0015] Combined with the first aspect and the above implementation manners, in some possible implementation manners, the method further includes: when it is detected that the temperature difference between the in-vehicle temperature and the out-vehicle temperature does not meet the condensation condition, sending a defrosting risk release message to the terminal associated with the vehicle, where the defrosting risk release message is used to indicate that there is no need to perform a vehicle relocation operation.

[0016] In the above technical solution, considering that after the target time period after receiving the confirmation message of the vehicle relocation reminder message, if no vehicle relocation operation is detected, the vehicle will directly execute the target anti-defrosting strategy, and after executing the target anti-defrosting strategy, there is no need for the user to perform a vehicle relocation operation anymore. Therefore, in order to avoid unnecessary vehicle relocation operations by the user in the future, the present application also proposes that when it is detected that the temperature difference between the in-vehicle temperature and the out-vehicle temperature does not meet the condensation condition, it indicates that the vehicle will not frost, and send a defrosting risk contact message to the terminal associated with the vehicle to remind the user that the defrosting risk has been released and there is no need to perform a vehicle relocation operation.

[0017] Combined with the first aspect and the above implementation manners, in some possible implementation manners, obtaining weather state information of the vehicle location where the vehicle is located includes: when the vehicle is in a locked state and there is no passenger in the vehicle interior, sending a vehicle usage reminder message to the terminal associated with the vehicle, where the vehicle usage reminder message is used to confirm the vehicle usage time; when receiving the vehicle usage time, obtaining the weather state information during the period from the current time to the vehicle usage time.

[0018] In the above technical solution, the present application also proposes that when the vehicle is in a locked state and there is no passenger in the vehicle interior, sending a vehicle usage reminder message to the terminal to determine the vehicle usage time of the user. After receiving the vehicle usage time, obtaining the weather state information during the period from the current time to the vehicle usage time, predicting whether there is a defrosting risk for the vehicle during the time period before the user uses the vehicle. If there is a risk, performing early prevention of vehicle defrosting to avoid the need for the user to deal with defrosting when using the vehicle, consuming the user's time, and if the defrosting is not thorough, it will also endanger driving safety.

[0019] Combined with the first aspect and the above implementation manners, in some possible implementation manners, the method further includes: determining a target time before the vehicle usage time based on a preset duration; when it is detected that the vehicle frosts at the target time, defrosting the vehicle.

[0020] In the above solution, the present application also proposes to set a preset duration, determining a target time before the vehicle usage time based on the preset duration. When reaching the target time, detecting whether the vehicle frosts; when the vehicle frosts, defrosting the vehicle in advance to ensure that when the user uses the vehicle, the defrosting operation of the vehicle has been completed, without the need for the user to operate manually, saving the user's waiting time for defrosting.

[0023] In combination with the second aspect and the above implementation manners, in some possible implementation manners, the first control module is further configured to determine a target anti-frosting strategy among candidate anti-frosting strategies to be activated based on the confirmation message for the strategy activation message when the temperature difference between the interior and exterior temperatures and the exterior humidity meet the condensation condition; and control the execution of the target anti-frosting strategy.

[0039] Next, the technical solutions in the present application will be clearly and elaborately described in conjunction with the accompanying drawings. Among them, in the description of the embodiments of the present application, unless otherwise specified, " / " means "or". For example, A / B may represent A or B. The "and / or" in the text is only a description of the association relationship between associated objects, indicating that there can be three relationships. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of the present application, "a plurality" means two or more than two.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0041] Figure 1 It is a schematic diagram of the implementation environment of a control method for preventing vehicle frosting provided by an embodiment of the present application. As Figure 1 shown, the implementation environment includes a vehicle 110 and a terminal 120.

[0042] The terminal 120 is a terminal held by the vehicle owner, or a terminal possessed by a driving object with driving authority over the vehicle 110. The terminal 120 may be a smart phone, a tablet computer, a smart watch, and other portable devices that can communicate with the vehicle.

[0043] The user realizes interaction with the vehicle 110 through the APP (Application) in the terminal 120. The vehicle 110 may send vehicle-related information to the terminal 120 so that the user can remotely understand the vehicle situation.

[0044] In the embodiments of the present application, when the vehicle 110 determines that there is a risk of frosting, it may send a vehicle relocation reminder message to the terminal 120 to remind the user of the risk of frosting and whether vehicle relocation is required. And upon receiving the confirmation message sent by the terminal 120 regarding the vehicle relocation reminder message, based on the confirmation message, control the vehicle control system 111 to perform corresponding operations.

[0045] Figure 2 It is a schematic flowchart of a control method for preventing vehicle frosting provided by the embodiments of the present application. It should be understood that this method can be applied to Figure 1 the vehicle 110 in

[0046] Exemplarily, as Figure 2 shown, the method 100 includes:

[0047] Step 201, obtain the weather status information of the vehicle location where the vehicle is located.

[0048] After the vehicle parks in the outdoor environment, when it may encounter weather with low temperature and high humidity, it may cause a risk of frosting on the vehicle. Therefore, for the outdoor parking scenario, corresponding strategies for preventing vehicle frosting need to be set. In a possible implementation manner, when it is detected that the vehicle is in the outdoor parking scenario, obtain the weather status information corresponding to the vehicle location where the vehicle is located, for determining whether there is a risk of frosting on the vehicle.

[0049] Regarding the acquisition method of the weather status information, the vehicle location where the vehicle is located can be obtained through GPS (Global Positioning System), and based on the vehicle location, obtain the weather forecast information corresponding to the vehicle location through the HUT (Head Unit) system as the weather status information. Exemplarily, the weather status information may include information such as weather type, humidity, precipitation, temperature, and air quality; the weather type includes sunny, light rain, heavy rain, or snowfall, etc.

[0050] Optionally, the weather status information may be the weather status information at the current moment, or the weather status information for a preset duration in the future from the current moment.

[0051] Exemplarily, when it is detected that the vehicle is in the outdoor parking scenario, obtain the current weather status information to determine whether there is a risk of frosting on the vehicle currently; or, when it is detected that the vehicle is in the outdoor parking scenario, obtain the weather status information for the next 10 hours to determine whether there is a risk of frosting on the vehicle within the next 10 hours.

[0052] Step 202, in the case where the weather status information indicates that there is a risk of frosting on the vehicle, send a vehicle relocation reminder message to the terminal associated with the vehicle.

[0053] Among them, the frosting risk refers to the situation where, in the case of rainfall, snowfall, or sudden temperature drop, a temperature difference is generated inside and outside the vehicle, and the humidity outside the vehicle is high, which may cause frosting on the vehicle. It is possible to judge whether there is a frosting risk for the vehicle based on the weather type, temperature, humidity, etc. in the weather status information.

[0054] When the weather status information indicates that the vehicle has a frosting risk, for example, there is going to be a heavy snowstorm, the vehicle can be parked in a non-open-air scenario by reminding the user to avoid the frosting risk caused by the heavy snowstorm on the vehicle. In one possible implementation, when the weather status information indicates that the vehicle has a frosting risk, a vehicle relocation reminder message is sent to the terminal associated with the vehicle. The vehicle relocation reminder message is used to remind the user that the vehicle has a frosting risk and to remind the user whether to perform a vehicle relocation operation.

[0055] Optionally, after the terminal receives the vehicle relocation reminder message, a vehicle relocation selection prompt can be displayed on the terminal interface for the user to operate and select whether to relocate the vehicle. The vehicle relocation selection prompt includes confirming to relocate the vehicle and confirming not to relocate the vehicle. When the terminal receives a selection operation on the vehicle relocation selection prompt, the selection result is fed back to the vehicle; if the selection operation indicates that the user selects to confirm relocating the vehicle, the terminal feeds back a confirmation message to the vehicle; if the selection operation indicates that the user selects to confirm not to relocate the vehicle, the terminal feeds back a confirmation of not relocating the vehicle to the vehicle.

[0056] Step 203, in the case of not receiving a confirmation message for the vehicle relocation reminder message, control the target sensor to be turned on to collect the in-vehicle temperature, the out-vehicle temperature, and the out-vehicle humidity of the vehicle. The target sensor includes at least a temperature sensor and a humidity sensor.

[0057] Among them, not receiving a confirmation message for the vehicle relocation reminder message includes that the user selects not to relocate the vehicle on the terminal associated with the vehicle, or the user does not perform a selection operation on the terminal.

[0058] When the vehicle has a frosting risk but the user chooses not to relocate the vehicle, if the temperature and humidity are not monitored and prevention is not carried out in a timely manner, it will lead to vehicle frosting. Before the user uses the vehicle next time, it takes time to defrost the vehicle. Therefore, it is necessary to automatically monitor and prevent vehicle frosting. In one possible implementation, in the case of not receiving a confirmation message from the user for the vehicle relocation reminder message, control the vehicle to turn on the target sensor. The target sensor includes at least a temperature sensor and a humidity sensor. The in-vehicle temperature and the out-vehicle temperature of the vehicle are collected by the temperature sensor, and the out-vehicle humidity of the vehicle is collected by the humidity sensor, which is used to jointly judge whether frosting prevention is required based on the out-vehicle temperature, the in-vehicle temperature, and the out-vehicle humidity.

[0059] Optionally, after receiving a confirmation message for the vehicle relocation reminder message, if no vehicle relocation operation is detected within a preset duration, a vehicle relocation reminder message is sent to the terminal associated with the vehicle again.

[0060] Step 204, when the temperature difference between the in-vehicle temperature and the out-vehicle temperature and the out-vehicle humidity meet the condensation condition, control the vehicle to execute the target anti-frosting strategy to reduce the temperature difference between the inside and outside of the vehicle.

[0061] Among them, the condensation condition is the threshold condition for the vehicle to frost, including the temperature difference threshold and the humidity threshold between the in-vehicle temperature and the out-vehicle temperature; the target anti-frosting strategy can be an air-conditioning refrigeration strategy, a window opening strategy, an air-conditioning external circulation strategy, a window heating strategy, etc.

[0062] Determine the temperature difference based on the in-vehicle temperature and the out-vehicle temperature. When the temperature difference between the in-vehicle temperature and the out-vehicle temperature is greater than or equal to the temperature difference threshold, and the out-vehicle humidity is greater than or equal to the humidity threshold, it indicates that the temperature difference between the inside and outside of the vehicle is too large and the out-vehicle humidity is too high, and the vehicle will frost. Then, it is necessary to control the vehicle to execute the target anti-frosting strategy to reduce the temperature difference between the inside and outside of the vehicle and avoid the occurrence of frosting.

[0063] Exemplarily, the condensation condition includes a temperature difference threshold of 10 degrees Celsius (°C) and a humidity threshold of 80% RH. The out-vehicle temperature of the vehicle is collected as 0 °C, the in-vehicle temperature is 12 °C, and the out-vehicle humidity is 85% RH. Based on the out-vehicle temperature and the in-vehicle temperature, the determined temperature difference is 12 °C, which is greater than the temperature difference threshold of 10 °C, and the out-vehicle humidity of 85% RH is greater than the humidity threshold of 80% RH. Then, it indicates that the vehicle currently has a frosting risk and needs anti-frosting treatment.

[0064] Optionally, based on different temperature differences and out-vehicle humidity, control the vehicle to execute different target anti-frosting strategies.

[0065] Exemplarily, when the temperature difference is greater than 20 °C and the out-vehicle humidity is greater than 90% RH, it indicates that the current vehicle has a high frosting risk, and execute the target anti-frosting strategy with a faster reduction rate of the temperature difference between the inside and outside (for example, the window opening strategy); when the temperature difference is less than 20 °C and the out-vehicle humidity is less than 90% RH, execute the target anti-frosting strategy with a slower reduction rate of the temperature difference between the inside and outside (for example, the window heating strategy).

[0066] In a possible implementation manner, when the temperature difference between the in-vehicle temperature and the out-vehicle temperature and the out-vehicle humidity do not meet the condensation condition, control the vehicle to stop executing the target anti-frosting strategy.

[0067] Optionally, during the process of controlling the vehicle to execute the target anti-frosting strategy, the temperature difference between the inside and outside of the vehicle and the outside humidity can be obtained in real time to determine whether to stop executing the target anti-frosting strategy. It is also possible to obtain the temperature difference between the inside and outside of the vehicle and the outside humidity when the duration of the vehicle executing the target anti-frosting strategy reaches a preset duration. When both the temperature difference and the outside humidity do not meet the condensation conditions, the vehicle is controlled to stop executing the target anti-frosting strategy.

[0068] Figure 3 It is a schematic diagram of preventing vehicle frosting provided by an embodiment of the present application. As Figure 3 shown, the GPS obtains the vehicle position, the HUT obtains the weather state information corresponding to the vehicle position, and sends the CAN signal corresponding to the obtained weather state information to the vehicle control system BCM. The BCM determines whether the weather state information indicates that the vehicle has a frosting risk; in the case where the weather state information indicates that the vehicle has a frosting risk, a vehicle moving reminder message is sent to the user terminal. If the user selects to perform a vehicle moving operation, the weather state information is continuously monitored; if the user selects not to perform a vehicle moving operation, the in-vehicle temperature, the outside temperature, and the outside humidity are identified through temperature sensors and humidity sensors, and the temperature difference is calculated based on the in-vehicle temperature and the outside temperature. When both the temperature difference and the outside humidity meet the condensation conditions, the vehicle is controlled to execute the air-conditioning refrigeration strategy and / or the window opening strategy; during the execution of the strategy, if it is detected that the temperature difference and the outside humidity do not meet the condensation conditions, the vehicle is controlled to stop executing the air-conditioning refrigeration strategy and / or the window opening strategy.

[0069] In summary, this embodiment provides a control method for preventing vehicle frosting: obtaining the weather state information of the location where the vehicle is located to determine whether the vehicle has a frosting risk. If the weather state information indicates that the vehicle has a frosting risk, a vehicle moving reminder message is sent to the associated terminal; in the case where the confirmation information for the vehicle moving reminder message is not received, the target sensor is controlled to be turned on to collect the in-vehicle temperature, the in-vehicle temperature, and the outside humidity of the vehicle. When the temperature difference and the outside humidity meet the condensation conditions, it indicates that the vehicle is more likely to frost, and the target anti-frosting strategy is automatically controlled to be executed to avoid vehicle frosting, eliminate driving hazards, and also save the user's time for defrosting treatment before using the vehicle; in addition, only when the confirmation information for the vehicle moving reminder message is not received, the target sensor is controlled to be turned on for frosting detection, which can avoid wasting the vehicle power consumption caused by continuously turning on the target sensor and improve the timeliness and accuracy of judging the vehicle frosting risk.

[0070] When the vehicle is in an open-air scenario, affected by factors such as sudden weather cooling, the vehicle may frost. If the vehicle is in a non-open-air scenario, weather factors will not cause the vehicle to frost. Therefore, when it is detected that the vehicle is in an open-air scenario, the user can be reminded to park the vehicle in a non-open-air scenario to eliminate the frosting risk.

[0071] Figure 4 is a schematic flowchart of another control method for preventing vehicle frosting provided by an embodiment of the present application. It should be understood that this method can be applied to Figure 1 the vehicle 110 in

[0072] Exemplarily, as Figure 4 shown, the method 400 includes:

[0073] Step 401, obtain the weather status information of the vehicle location where the vehicle is located.

[0074] The implementation manner of step 401 can refer to the above embodiment, and this embodiment will not be elaborated here.

[0075] Step 402, when the weather status information indicates that the vehicle has a frosting risk, detect whether the vehicle is in an open-air scene.

[0076] In the case of heavy rain or snowfall, if the vehicle is parked in an open-air scene, due to the large temperature difference between the inside and outside of the vehicle and the high humidity outside the vehicle, there will be a frosting risk for the vehicle. However, if the vehicle is in a non-open-air scene such as an underground parking lot or a garage, the influence of the external weather on the indoor temperature and humidity is small, and the vehicle will not frost. In a possible implementation manner, in order to more accurately determine whether to send a vehicle relocation reminder message to the terminal, when the weather status information indicates that the vehicle has a frosting risk, based on the vehicle location where the vehicle is located, detect whether the vehicle is in an open-air scene to determine whether to send a vehicle relocation reminder message to the terminal to remind the user to park the vehicle in a non-open-air scene.

[0077] Step 403, when the vehicle is in an open-air scene, send a vehicle relocation reminder message to the terminal associated with the vehicle.

[0078] In an open-air scene, the vehicle will frost due to the influence of temperature and humidity. To prevent the vehicle from frosting, remind the user to park the vehicle indoors to reduce the frosting risk of the vehicle. In a possible implementation manner, when the vehicle is in an open-air scene, send a vehicle relocation reminder message to the terminal associated with the vehicle to confirm whether the user needs to perform a vehicle relocation operation.

[0079] Optionally, if it is detected that the vehicle is in a non-open-air scene, the influence of outdoor weather changes on indoor temperature and humidity is small, the temperature difference between the inside and outside of the vehicle and the humidity outside the vehicle will not reach the condensation condition, and the vehicle will not frost, then there is no need to send a vehicle relocation reminder message to the terminal.

[0080] Step 404, when the confirmation message for the vehicle relocation reminder message is not received, send a policy enabling message to the terminal associated with the vehicle, and the policy enabling message is used to confirm whether to execute the anti-frosting policy.

[0081] In the case where the confirmation information for the vehicle relocation reminder message is not received, if the condensation condition is met, the vehicle can independently execute the target frost prevention strategy; while in some scenarios, the user may think that there is no need to prevent the frost risk, that is, there is no need to relocate the vehicle and no frost prevention is carried out; then, in order to more accurately determine whether the target frost prevention strategy needs to be executed. In a possible implementation manner, when the confirmation information for the vehicle relocation reminder message is not received, the vehicle can send a strategy enabling message to the terminal associated with the vehicle to confirm with the user whether the target frost prevention strategy needs to be executed.

[0082] Optionally, the strategy enabling message may further include at least two candidate frost prevention strategies for the user to select the target frost prevention strategy to be taken after determining to execute the target frost prevention strategy. The candidate frost prevention strategies may include an air conditioner refrigeration strategy, a window opening strategy, an air conditioner external circulation strategy, a window heating strategy, etc.

[0083] Step 405, in the case where the confirmation information for the strategy enabling message is received, control to turn on the target sensor to collect the vehicle's interior temperature, exterior temperature, and exterior humidity.

[0084] Among them, the confirmation information for the strategy enabling message at least includes the authorization information for the user to perform frost prevention treatment on the vehicle, which is used to instruct the vehicle to turn on the target sensor to collect the vehicle's interior temperature, exterior temperature, and exterior humidity; in the case where the strategy enabling message further includes at least two candidate frost prevention strategies, the confirmation information for the strategy enabling message may further include the target frost prevention strategy selected by the user from the candidate frost prevention strategies, which is used to instruct the vehicle to control the execution of the target frost prevention strategy selected by the user when the temperature difference between the interior and exterior temperatures and the exterior humidity meet the condensation condition.

[0085] In a possible implementation manner, when the confirmation information for the strategy enabling message is received, it indicates that the user authorizes the vehicle to automatically perform frost prevention treatment, and then control the vehicle to turn on the temperature sensor to collect the vehicle's interior temperature and exterior temperature, and turn on the humidity sensor to obtain the vehicle's exterior humidity.

[0086] Step 406, in the case where the temperature difference between the interior temperature and the exterior temperature and the exterior humidity meet the condensation condition, based on the confirmation information for the strategy enabling message, determine the target frost prevention strategy among the candidate frost prevention strategies to be enabled.

[0087] When the temperature difference between the interior temperature and the exterior temperature and the exterior humidity meet the condensation condition, the vehicle is about to frost, and then based on the candidate frost prevention strategy selected by the user in the confirmation information for the strategy enabling message, determine the target frost prevention strategy to be enabled.

[0088] Step 407, control the execution of the target anti-frost strategy.

[0089] After determining the target anti-frost strategy to be enabled based on the user's confirmation information, control the vehicle to execute the above target anti-frost strategy.

[0090] In this embodiment, the present application also proposes that when the weather condition information indicates that there is a risk of frosting on the vehicle, detect whether the vehicle is in an open-air scenario to more accurately determine whether the weather condition information will have an adverse impact on the vehicle. If the vehicle is in an open-air scenario, it indicates that the weather condition information will have an impact on the vehicle and cause the vehicle to frost. Send a reminder message to move the vehicle to the terminal associated with the vehicle, reminding the user that the vehicle can be parked in a non-open-air scenario to prevent the vehicle from frosting. If the vehicle is in a non-open-air scenario, it indicates that the weather condition information will not cause the vehicle to frost, and there is no need to send a reminder message to move the vehicle to the terminal, making the sending of the reminder message to move the vehicle more in line with the actual situation and avoiding sending invalid reminders to the user.

[0091] Secondly, the present application also proposes that if the confirmation information of the reminder message to move the vehicle is not received from the user, it indicates that the user may use the vehicle in the near future and there is no need to move the vehicle. Then send a strategy enabling information to the terminal associated with the vehicle to confirm whether the vehicle needs to execute the anti-frost strategy. When the confirmation information of the strategy enabling information is received, control the activation of the target sensor to collect the temperature inside the vehicle, the temperature outside the vehicle, and the humidity outside the vehicle; in the case where the user chooses not to move the vehicle, send the strategy enabling information to the terminal again, and let the user independently decide whether to execute the anti-frost strategy, making the processing of anti-frost more flexible and more in line with the actual needs of the user.

[0092] Finally, the present application also proposes that the strategy enabling information further includes at least two candidate anti-frost strategies for the user to select the target anti-frost strategy to be adopted; when both the temperature difference between the temperature inside the vehicle and the temperature outside the vehicle and the humidity outside the vehicle meet the condensation conditions, based on the user's confirmation information of the strategy enabling information, determine the target anti-frost strategy among the candidate anti-frost strategies to be enabled, and control the vehicle to execute the above target anti-frost strategy. The user can select the target anti-frost strategy according to the current needs to achieve the purpose of preventing frosting while selecting a suitable target anti-frost strategy.

[0093] Obtain the user's vehicle usage time in advance, and judge whether there is a risk of frosting on the vehicle before the vehicle usage time. In the case where there is a risk of frosting on the vehicle, take preventive measures in advance, making the execution of the anti-frost strategy more in line with the actual travel needs of the user and providing convenience for the user.

[0094] Figure 5 It is a schematic flowchart of another control method for preventing vehicle frosting provided by the embodiment of the present application. It should be understood that this method can be applied to Figure 1Vehicle 110 therein.

[0095] Exemplarily, as Figure 5 shown, the method 500 includes:

[0096] Step 501, when the vehicle is in a locked state and there is no passenger in the vehicle, send a vehicle usage reminder message to the terminal associated with the vehicle, where the vehicle usage reminder message is used to confirm the vehicle usage time.

[0097] Combined with the actual vehicle usage time of the user, judging whether there is a risk of frosting on the vehicle during the period before the user uses the vehicle, and performing preventive frosting treatment in advance can effectively avoid potential safety hazards caused by vehicle frosting before the user uses the vehicle. In a possible implementation, when the vehicle is in a locked state and there is no passenger in the vehicle, it means that the user has left the vehicle and will not use the vehicle temporarily. A vehicle usage reminder message can be sent to the terminal associated with the vehicle to confirm the user's estimated vehicle usage time, which is used to judge whether there is a risk of frosting before the user uses the vehicle, and when it is determined that there is a risk of frosting, prevent vehicle frosting in advance to save the user's time for defrosting the vehicle.

[0098] Step 502, when receiving the vehicle usage time, obtain the weather status information during the period from the current time to the vehicle usage time.

[0099] When receiving the vehicle usage time sent by the terminal, obtain the weather status information during the period from the current time to the vehicle usage time, which is used to judge whether there is a risk of frosting on the vehicle before the user uses the vehicle, whether vehicle relocation is needed, and whether preventive frosting treatment is needed.

[0100] Optionally, when the vehicle usage time is not received, send the vehicle usage reminder message again at intervals of a preset duration, or obtain the weather status information for the next 24 hours, judge whether there is a risk of frosting. When there is a risk of frosting, control the target sensor to collect the outside temperature, inside temperature and outside humidity of the vehicle. When the temperature difference between the inside and outside of the vehicle and the outside humidity meet the condensation conditions, control the implementation of the preventive frosting strategy.

[0101] Optionally, based on the user's historical vehicle usage time, determine the common vehicle usage time, obtain the weather status information during the period from the current time to the common vehicle usage time, and judge whether there is a risk of frosting on the vehicle based on this weather status information.

[0102] Step 503, when the weather status information indicates that there is a risk of frosting on the vehicle, send a vehicle relocation reminder message to the terminal associated with the vehicle.

[0103] Step 504, when the confirmation information for the vehicle relocation reminder message is not received, control the target sensor to collect the inside temperature, outside temperature and outside humidity of the vehicle.

[0104] Step 505: When the temperature difference between the in-vehicle temperature and the out-vehicle temperature and the out-vehicle humidity meet the condensation condition, control the execution of the target anti-frosting strategy.

[0105] The implementation manners of Steps 503 to 505 can refer to the above embodiments, and are not elaborated herein.

[0106] Step 506: When receiving the confirmation information for the vehicle relocation reminder message, detect whether a vehicle relocation operation is received within the target time period.

[0107] After receiving the confirmation information sent by the terminal from the user for the vehicle relocation reminder message, if the user does not perform the vehicle relocation operation in time, the vehicle may frost before the user relocates the vehicle. In order to avoid vehicle frosting caused by the user not relocating the vehicle in time, in a possible implementation manner, a target time period is set. When the vehicle receives the confirmation information for the vehicle relocation reminder message, detect whether a vehicle relocation operation is received within the target time period to determine whether subsequent automatic anti-frosting processing is still required.

[0108] Optionally, the target time period can be a preset fixed duration value; it can also be the duration between the time when the confirmation information for the vehicle relocation reminder message is received and the time when the weather status information indicates that there is a frosting risk for the vehicle.

[0109] Exemplarily, taking the time of sending the vehicle relocation reminder message to the terminal as 9:00, the time of receiving the confirmation information for the vehicle relocation reminder message as 10:00, and the time when the weather status information indicates snowfall as 17:00 as an example, taking 5 hours as the preset target time period, it can be detected whether a vehicle relocation operation is received between 10:00 and 15:00; it can also take the duration of 7 hours between the time of receiving the confirmation information for the vehicle relocation reminder message at 10:00 and the time of snowfall at 17:00 as the target time period, and detect whether a vehicle relocation operation is received within this target time period.

[0110] Step 507: When no vehicle relocation operation is detected, control to turn on the target sensor to collect the in-vehicle temperature, out-vehicle temperature, and out-vehicle humidity of the vehicle.

[0111] When the user does not perform the vehicle relocation operation within the target time period, it is necessary to automatically control the vehicle to perform anti-frosting processing. In order to avoid vehicle frosting before the user performs the vehicle relocation operation, in a possible implementation manner, when the vehicle does not detect a vehicle relocation operation, control to turn on the temperature sensor to collect the in-vehicle temperature and out-vehicle temperature of the vehicle, turn on the humidity sensor to collect the out-vehicle humidity, and based on the in-vehicle temperature, out-vehicle temperature, and out-vehicle humidity, determine the timing of performing anti-frosting processing.

[0112] Optionally, when no vehicle moving operation is detected within the target time period, a vehicle moving reminder message is sent again to a terminal associated with the vehicle, and the target sensor is controlled to be turned on to collect the temperature inside the vehicle, the temperature outside the vehicle, and the humidity outside the vehicle.

[0113] Step 508, when it is detected that the temperature difference between the temperature inside the vehicle and the temperature outside the vehicle does not meet the condensation condition, frost risk relief information is sent to a terminal associated with the vehicle, and the frost risk relief information is used to indicate that there is no need to perform the vehicle moving operation.

[0114] Before the user moves the vehicle, if the temperature difference between the temperature inside the vehicle and the temperature outside the vehicle is reduced after the target frost prevention strategy is executed, and the vehicle will not be frosted, the user does not need to move the vehicle. In order to avoid the user from performing unnecessary vehicle moving operations later, in one possible implementation, the vehicle obtains the temperature difference between the temperature inside the vehicle and the temperature outside the vehicle in real time, and when the temperature difference is less than the temperature difference threshold in the condensation condition, a frost risk elimination message is sent to the terminal associated with the vehicle to remind the user that the vehicle frost risk has been eliminated and there is no need to move the vehicle.

[0115] In this embodiment, the application also proposes that when the vehicle is in a locked state and there are no passengers inside the vehicle, a vehicle usage reminder message is sent to the terminal to determine the user's vehicle usage time. After receiving the vehicle usage time, weather status information from the current time to the vehicle usage time is obtained to predict whether there is a risk of frost on the vehicle in the time period before the user uses the vehicle. If there is a risk, frosting of the vehicle is prevented in advance to avoid the need to deal with frost when the user uses the vehicle, which wastes the user's time. If defrosting is not thorough, it will also endanger driving safety.

[0116] Secondly, considering that if the time between receiving the confirmation information of the car moving reminder information and receiving the user's car moving operation is long, the vehicle may have been frosted, the present application also proposes to detect whether the user's car moving operation is received within the target time period after receiving the confirmation information of the car moving reminder information; if the car moving operation is not received, the target sensor is controlled to turn on, collect the vehicle's indoor temperature, outdoor temperature and outdoor humidity, and when the temperature difference between the indoor temperature and the outdoor temperature and the outdoor humidity meet the condensation condition, the vehicle is controlled to execute the target frost prevention strategy. In the case that the user confirms to move the car but does not move the car within the target time period, the target sensor is automatically controlled to turn on, and the indoor temperature, outdoor temperature and outdoor humidity are detected. When the temperature difference and the outdoor humidity meet the condensation condition, the target frost prevention strategy is controlled to be executed.

[0117] Again, the present application also proposes setting a preset time, and determining a target time before the vehicle is used based on the preset time. When the target time is reached, it is detected whether the vehicle is frosted. If the vehicle is frosted, the vehicle is defrosted in advance to ensure that the defrosting operation of the vehicle has been completed when the user returns to the vehicle, without the need for manual operation by the user, thus saving the user time waiting for defrosting.

[0118] Finally, considering that if no moving operation is detected within the target time period after receiving the confirmation information of the car moving reminder information, the vehicle will directly execute the target frost prevention strategy, and the user does not need to perform the car moving operation after executing the target frost prevention strategy, in order to avoid the user from performing unnecessary car moving operations later, the present application also proposes that when it is detected that the temperature difference between the temperature inside the car and the temperature outside the car does not meet the condensation conditions, it indicates that the vehicle will not frost, and frost risk contact information is sent to the terminal associated with the vehicle to remind the user that the frost risk has been eliminated and there is no need to perform the car moving operation.

[0119] In one possible scenario, the vehicle may already be frosted before the user uses the vehicle. In order to avoid the user having to manually defrost the vehicle before using the vehicle, after obtaining the user's vehicle use time, defrost can be performed in advance before the vehicle use time.

[0120] In order to prevent the vehicle from being frosted while the user is using the vehicle and requiring the user to manually defrost the vehicle, a possible implementation method is to set a preset duration, determine a target time before the vehicle is used based on the acquired vehicle use time and the preset duration, and when the target time is reached, detect whether the vehicle is frosted, and defrost the vehicle if frosting is detected.

[0121] Among them, the defrost operation may include turning on the air conditioner, turning on the front windshield heating, turning on the exterior rearview mirror heating and other operations.

[0122] For example, if the received vehicle usage time is 15:30 and the preset duration is set to 10 minutes, the determined target time is 15:20, indicating that the vehicle needs to be tested for frost at 15:20. When frost is detected on the vehicle, the air conditioner is turned on to defrost the vehicle.

[0123] Optionally, the defrost operation may be set in advance, or the degree of frosting of the vehicle may be detected, and based on the degree of frosting, different defrost operations may be determined to defrost the vehicle.

[0124] Optionally, the process of determining the degree of frosting of the vehicle may be to obtain a window image of the vehicle, analyze a haze value of the window based on the window image, and determine the degree of frosting of the vehicle based on the haze value, wherein a higher haze value indicates a higher degree of frosting.

[0125] Exemplarily, when vehicle frosting is detected, the air conditioner, front windshield heating, and outside rearview mirror heating are simultaneously turned on for defrosting; or, if the haze value is in the range of [2%, 30%), it is determined that the vehicle has mild frosting, and then the defrosting operation of turning on the air conditioner is taken; if the haze value is in the range of [30%, 65%), it is determined that the vehicle has moderate frosting, and then the defrosting operation of turning on the air conditioner and the outside rearview mirror heating is taken; if the haze value is in the range of [65%, 100%), it is determined that the vehicle has severe frosting, and then the defrosting operation of turning on the air conditioner, the front windshield heating, and the outside rearview mirror heating is taken.

[0126] Optionally, the above preset duration can be set by the vehicle manufacturer before the vehicle leaves the factory, can also be set independently by the user, or can also be based on the current weather state information to determine different preset durations.

[0127] Optionally, receive the user's first vehicle usage time, determine the first target time based on the first vehicle usage time and the preset duration. When the first target time is reached, if vehicle frosting is detected, send a reminder message to the user, determine whether the user uses the vehicle at the first vehicle usage time. When the user's confirmed vehicle usage information is received, defrost the vehicle; when the user's confirmed vehicle usage information is not received, send the reminder message again after an interval of the first duration; when it is confirmed that the user does not use the vehicle at the first vehicle usage time, confirm the second vehicle usage time with the user, determine the second target time based on the second vehicle usage time and the preset duration, and defrost the vehicle when the second target time is reached, so as to avoid repeated defrosting due to the change of the user's vehicle usage time and reduce the waste of vehicle power consumption.

[0128] Exemplarily, the preset duration is 5 minutes and the first vehicle usage time is 11:45, then the first target time is 11:40. If vehicle frosting is detected at 11:40, send a reminder message to the user. If the user confirms to use the vehicle at 11:45, defrost the vehicle; if the user's confirmed vehicle usage information is not received and the repeated reminder duration is set to 2 minutes, send the reminder message again at 11:42; if it is confirmed that the user does not use the vehicle at 11:45 and the second vehicle usage time confirmed with the user is 12:30, then the second target time is 12:25, and the vehicle is defrosted at 12:25.
