The following describes a defrosting method and apparatus for a vehicle outside a vehicle cabin windshield according to an embodiment of the present application with reference to the accompanying drawings. Aiming at the technical problems that when a one-key vehicle preparation or remote air conditioning function is used in the related technology mentioned in the background technology center, defrosting waiting cannot be solved, defrosting probability is high by remote misestimation, defrosting speed is reduced, vehicle use experience is reduced and the like. Therefore, the technical problems that defrosting waiting cannot be solved, defrosting probability is high when remote misestimation is started, defrosting speed is reduced, vehicle use experience is improved and the like when a one-key standby vehicle or remote air conditioning function is used in the related technology are solved.
Specifically, fig. 1 is a schematic flow chart of a defrosting method for a front windshield of a vehicle cabin according to an embodiment of the present application.
As shown in fig. 1, the defrosting method for the front windshield outside the vehicle cabin comprises the following steps:
in step S101, temperature and humidity, wind speed, illumination intensity, user reservation vehicle and/or vehicle habit statistical information of the current position of the target vehicle are obtained, and a first front windshield frosting risk level of the target vehicle is identified.
In the actual execution process, the embodiment of the application can be applied to a server such as a vehicle networking data platform, and provides high-quality processing capability for vehicle data information, so that resource allocation is more reasonable, for example, a target vehicle can be one or more vehicles, the resource utilization rate is effectively improved, the method is more reasonable and reliable, environmental data of the current vehicle position and user reservation vehicle and/or vehicle habit statistical information are received, and therefore the first front windshield frosting risk level of the vehicle is identified.
Specifically, the embodiment of the application can acquire the temperature and humidity, the wind speed, the illumination intensity and the user reservation vehicle and/or the vehicle habit statistical information of the current position of the target vehicle, and acquire the corresponding saturation temperature through the environmental humidity of the current position. The cloud temperature difference deltatc is obtained by subtracting the ambient temperature of the current position from the saturation temperature, wherein in the embodiment of the application, the ambient temperature can be the default front windshield temperature, and subtracting 0 ℃ from the ambient temperature to obtain the ambient temperature difference deltat 1, which is used for grading and is used as the first frosting risk grading basis. In addition, besides the temperature, the humidity, the wind speed and the illumination intensity, the application combines the statistical information of the reserved vehicles and/or the vehicle habits of the users to accurately identify the actual front windshield frosting risk level of the target vehicle, thereby defrosting when the risk level meets a certain defrosting condition, avoiding waiting for defrosting, avoiding the situation of starting defrosting by remote misestimation, effectively improving the defrosting rate and improving the vehicle experience.
Optionally, in one embodiment of the present application, before identifying the first front windshield frosting risk level of the target vehicle, the method further includes: judging whether the target vehicle is in an indoor environment or not based on the current position; if the target vehicle is in an indoor environment, the defrosting action is not performed.
It can be appreciated that when the vehicle is in an indoor environment, the vehicle is not prone to frosting, and there is no defrosting requirement. In the actual implementation process, the embodiment of the application can judge whether the current parking place accords with the indoor environment characteristics or not according to the current parking place of the vehicle, namely the place where the vehicle is finally positioned before the locking of the vehicle, through the vehicle networking data platform, thereby filtering the parking scene of the garage, further improving the defrosting accuracy, ensuring that the defrosting action is executed in the scene outside the parking of the garage, and being more intelligent and reasonable. That is, the application can eliminate the need of executing defrosting actions when judging that the vehicle is in the indoor garage parking scene, thereby improving the intelligent level of the vehicle, saving energy and reducing consumption.
Optionally, in one embodiment of the present application, after identifying the first front windshield frosting risk level of the target vehicle, the method further includes: judging whether the first front windshield frosting risk level meets a preset reminding condition or not; and if the first front windshield frosting risk level meets the preset reminding condition, sending a remote defrosting starting reminding signal to a user so as to control a wiper of the vehicle to execute defrosting actions every preset time period after the user sends an instruction based on the remote defrosting starting reminding signal until the preset defrosting time period is reached.
It can be understood that in the embodiment of the application, environmental factors such as temperature and humidity can be used as reminding conditions, when the frosting risk level meets the preset reminding conditions, if the frosting risk level is greater than a certain level, the embodiment of the application can send reminding signals to the mobile phone end of the user through the internet of vehicles data platform, and can enable the user to receive defrosting reminding in a mode of vibrating or ringing the mobile terminal by sending the reminding signals, so that the user can timely process defrosting tasks.
In addition, after the user allows the defrosting operation, the user can set a certain defrosting time period, such as 10min, at the mobile phone end, so that the windscreen wiper of the vehicle can be ensured to execute the defrosting operation at intervals of a certain time period, such as 10s, within the certain defrosting time period.
For example, in the embodiment of the present application, Δtc may be obtained by subtracting the cloud local environment temperature from the corresponding saturation temperature in the remote local environment humidity, and Δt1 may be obtained by subtracting 0 ℃ from the ambient temperature. When the delta T is smaller than 0 ℃, grading according to the delta T1, and taking the grading as a frosting risk grade grading basis, thereby obtaining the frosting risk grade LCx. The embodiment of the application can correct the frosting risk level LCx by combining cloud wind speed information, cloud illumination intensity and reserved vehicle use time. And sending a remote defrosting starting reminding signal to a user through remote interaction modes such as APP and the like under the condition that the corrected first frosting risk level LCrx and reserved vehicle time meet preset reminding conditions, and controlling a wiper of the vehicle to execute defrosting actions every preset time period based on the remote defrosting starting instruction sent by the user until the preset defrosting time period is reached. The embodiment of the application can correlate the effect of the windscreen wiper on the defrosting speed of the front windshield, can improve the defrosting speed and the vehicle experience, saves energy and reduces consumption.
In step S102, the first front windshield frosting risk level and the second front windshield frosting risk level identified by the target vehicle according to the temperature and humidity, the illumination intensity and the remote vehicle opening time information of the current environment are combined to obtain the final front windshield frosting risk level of the vehicle.
It can be understood that if the final front windshield frosting risk level of the vehicle is identified only by using the cloud, detailed environmental information of the environment where the vehicle is parked cannot be obtained, misjudgment is caused on the final front windshield frosting risk level of the vehicle, and therefore environmental information such as the temperature, humidity, illumination intensity and the like of the current environment where the vehicle is collected by combining with the vehicle end, the final front windshield frosting risk level of the vehicle is obtained, the judgment result is more accurate, and the defrosting accuracy is further improved.
In the actual execution process, the embodiment of the application can receive the temperature and humidity, the illumination intensity and the remote vehicle starting time of the current environment of the vehicle through the vehicle end server, so as to identify the second front windshield frosting risk level of the vehicle flow. In addition, besides the temperature, humidity, wind speed and illumination intensity, the application also combines the remote vehicle starting time of the user so as to judge whether the vehicle needs to defrost in advance according to the weather information of the reserved use time of the user, and if the weather information of the reserved time is judged not to defrost in advance, the defrosting task is not required to be executed, so that the application is more intelligent and practical, and achieves the effects of energy conservation and consumption reduction. Further, the embodiment of the application can combine the first front windshield frosting risk level and the second front windshield frosting risk level to obtain the final front windshield frosting risk level of the vehicle.
Specifically, when a user starts a one-key standby or remote air conditioning function through an APP, the embodiment of the application can control the vehicle-end humidity sensor and the temperature sensor to detect the ambient humidity and the ambient temperature respectively, find the corresponding saturated temperature through the actually measured ambient humidity, subtract the actually measured ambient temperature from the saturated temperature, thereby obtaining the vehicle-end temperature difference delta TV, subtract the ambient temperature by 0 ℃ to obtain the ambient temperature difference delta T2, and use the ambient temperature difference delta TV as a second frosting risk grade division basis for grading. And obtaining the final front windshield frosting risk level of the vehicle by carrying out double evaluation on the first front windshield frosting risk level and the second front windshield frosting risk level. According to the embodiment of the application, the frosting risk level calculated by the vehicle end information and the frosting risk level calculated by the cloud end are subjected to double evaluation, so that the final frosting risk is determined, and the intelligent level of the vehicle is improved.
In step S103, when the final front windshield frosting risk level meets the preset defrosting condition, controlling the wiper of the target vehicle to execute defrosting action every preset time period until reaching the preset defrosting time period, and completing defrosting of the front windshield glass outside the cabin.
