Description

Vehicle defrosting method, device, server and storage medium
Technical Field
The embodiment of the invention relates to the technical field of vehicle defrosting control, in particular to a vehicle defrosting method, a vehicle defrosting device, a server and a storage medium.
Background
When the vehicle is placed outdoors for a long time in winter, an ice layer can be formed on the windshield glass to shield the view of a driver. Normally, the purging may be performed by a defrost system installed on the vehicle. The conventional vehicle defrosting system can be divided into manual defrosting and automatic defrosting, wherein the manual defrosting refers to that a user activates a defrosting function by manually pressing a switch when discovering that the windshield is frosted and blocking the sight; the automatic defrosting refers to that after a vehicle is started, a defrosting system monitors whether a windshield is in a frosting state or not, and if the windshield is in the frosting state, a defrosting function is activated.
Manual defrosting requires manual operation by a user each time, which consumes labor. Therefore, the application of automatic defrosting is more extensive. In the prior art, during the driving process (the vehicle is started), the defrosting or defogging function is automatically started according to the judgment of the temperature and the humidity inside and outside the vehicle when the possibility of frosting or fogging is judged. However, this method cannot work when the vehicle is turned off, and cannot be applied to a situation where the driver stops the vehicle outdoors and the vehicle frosts, for example, a situation where the vehicle is placed outdoors in winter to defrost glass, because the vehicle is turned off at this time, the defrosting system is not in a working state, and if the driver wants to defrost, the driver can only start the vehicle first and then manually activate defrosting or automatically activate defrosting by means of the system. In order to solve the problems, a user can send a remote defrosting instruction to start the defrosting of the vehicle, and although the mode is suitable for a scene that the vehicle stops outdoors when flameout, certain travel convenience is provided for the user, but real convenience cannot be provided for the user who cannot know the outdoor environment.

As shown in fig. 1, the method may specifically include:
and S110, acquiring the external environment information of the vehicle to be defrosted.
The defrosting vehicle is a vehicle which is started in an flameout state and needs defrosting. The flameout state refers to a state that a driver turns off a vehicle power system by pressing an ignition switch, so that the vehicle cannot drive to run through the power system of the driver. The starting state can be acquired from the vehicle, whether defrosting is needed or not can be determined according to a selection instruction of a user, if the user determines that the current vehicle needs defrosting, a defrosting selection instruction can be sent to the vehicle defrosting device, and the vehicle defrosting device can respond to the defrosting selection instruction and defrost the current vehicle by the vehicle defrosting method of the embodiment.
The external environment information refers to environment information outside the vehicle to be defrosted, and may specifically include external environment temperature and external environment humidity. The vehicle defroster can acquire the temperature and humidity of the environment outside the vehicle, which are collected by the temperature sensor and the humidity sensor installed on the vehicle and continuously working in a flameout state, or the temperature sensor and the humidity sensor installed on the road facility.
And S120, determining defrosting time according to the environment information outside the vehicle and the environment information inside the vehicle before flameout of the vehicle to be defrosted.

Δ T may be represented by the formula Δ T ═ F (T)1-T3Δ T), where z ═ F (x, y) is a temperature change curve, specifically referring to fig. 3, fig. 3 is a schematic diagram of the temperature change curve in the first embodiment of the present invention, x is Δ T, y is a difference between T1 and T3, T1 represents the vehicle interior temperature before flameout, T3 represents the current vehicle exterior ambient temperature, and z is a temperature change amount of the vehicle interior over x time when the temperature difference is y. For the temperature variation curve of fig. 3, curve a, curve B and curve C represent the in-vehicle temperature variation curves of different time periods, respectively, and the corresponding temperature variation is Δ T1、ΔT2And Δ T3。
The current time in-vehicle humidity of the vehicle to be defrosted can be represented by the formula H2 ═ H1- Δ H, where H2 represents the current time in-vehicle humidity, H1 represents the in-vehicle humidity before flameout, and Δ H represents the amount of change in the in-vehicle humidity of the vehicle in the time period Δ t from before flameout to the current time. Δ H can be represented by the formula Δ H ═ F (H)1-H3Δ t), where z ═ F (x, y) is a humidity change curve, specifically referring to fig. 4, fig. 4 is a schematic diagram of the humidity change curve in the first embodiment of the present invention, x is Δ t, y is a difference between H1 and H3, H1 represents the humidity in the vehicle before flameout, H3 represents the current ambient humidity outside the vehicle, and z is a change amount of the humidity in the vehicle after x time when the humidity difference is y. For the humidity change curves of fig. 4, curves D, E and F respectively represent the humidity change curves in the vehicle at different time periods, and the corresponding humidity changes are Δ H1、ΔH2And Δ H3。
And S122, determining the current frosting amount according to the environment information outside the vehicle, the environment information inside the vehicle at present and the frosting amount query table in the frosting level model.
Specifically, the time from before flameout to the current time is divided according to a set time interval, the frosting amount is determined for each time period, and the current frosting amount is obtained through accumulationAmount of frost. If the set time interval is a, the frosting amount in the ith time period can be determined by the formula Yi＝S(HDifference (D)，Tti+a，ΔTa) To obtain wherein Y isiDenotes the amount of frosting in the i-th time period, HDifference (D)Represents the difference between the ambient humidity outside the vehicle and the ambient humidity inside the vehicle at time ti + a, where ti represents the initial time of the i-th time period, Δ TaRepresents a change value T of the ambient temperature in the vehicle from time ti to time ti + ati+aRepresenting the ambient temperature outside the vehicle at time ti + a. Calculating to obtain HDifference (D)、ΔTaAnd Tti+aThereafter, by referring to the frosting amount look-up table, the frosting amount can be determined.

The preset trip time can be the trip time which is sent to the cloud platform in fig. 2 by the user before next trip according to actual needs, and specifically can be sent by the terminal in fig. 2.
Specifically, according to the preset trip time and the defrosting time, determining the defrosting starting time of the vehicle to be defrosted may include: determining theoretical travel time, wherein the theoretical travel time is the sum of the current moment, defrosting time and starting time of a vehicle to be defrosted; and when the difference value between the theoretical travel time and the preset travel time is less than the time threshold, determining that the current moment is the defrosting starting time. The theoretical trip time is the virtual time set in this embodiment, and the defrosting start time is determined by comparing the theoretical trip time with the preset trip time. When the theoretical trip time is greater than the preset trip time, it is described that defrosting is not in time at the current moment, and remote defrosting cannot be performed.
