[0003] When using a car, car drivers often encounter the situation of temporarily stopping on the roadside to do something. Because the time is short, they often do not close the windows after closing the door; or when they need to leave the car for a long time, they forget to close the windows, or only close some of the windows; in hot weather, in order to reduce the temperature inside the car under the sun, they will also open the windows after turning off the engine.

[0004] When the car owner leaves the car and does not close the windows, if the weather suddenly turns bad and it starts to rain, rain will enter the car through the open windows, soaking the items in the car and causing losses to the car owner. Summary of the Invention

[0005] The embodiments of the present application provide an automatic window closing method, system, computer, and storage medium to solve the technical problem in the prior art that, because the owner does not close the windows when leaving the car, rainwater enters the car through the open windows when it rains, causing losses to the owner.

[0045] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is described and illustrated below in conjunction with the accompanying drawings and examples.

[0047] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it refer to independent or alternative embodiments that are mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments unless there is a conflict.

[0048] See also Figure 1 The first embodiment of the present invention provides an automatic window closing method, which includes the following steps:

[0049] Step S10: determining whether the driver has left the vehicle by acquiring the real-time status of the vehicle;

[0050] When the driver is out of the vehicle, the operating conditions of some devices in the vehicle are different from those when the driver is in the vehicle. By obtaining the operating conditions of several devices, that is, the real-time status of the vehicle, it is possible to determine whether the driver stays in the vehicle, and then perform subsequent window closing determinations. In the operating state or the parked state, since the driver still stays inside the vehicle, there is no need to perform automatic window closing operations. By determining whether the vehicle is in a parked state, energy consumption can be effectively saved.

[0051] Step S20: If the driver is in the vehicle-leaving state, obtaining the vehicle window status and determining whether the window status is open;

[0052] When the driver is leaving the vehicle, the window status of the vehicle is obtained to further determine whether an automatic window closing operation is required. If the window status is closed, it means that the driver has completed the window closing action independently, and there is no need to perform subsequent window closing determination, which further saves the vehicle's energy consumption.

[0053] Step S30: If the window is in the open state, obtaining the external precipitation speed and external precipitation time of the vehicle;

[0054] When the driver is leaving the vehicle and the window is in the open state, it is determined that a subsequent automatic window closing judgment needs to be performed. By obtaining the external precipitation speed of the vehicle, the contact speed of the vehicle with water can be obtained, and the contact time of the vehicle with water can be obtained by the external precipitation time.

[0055] Step S40: determining whether it is raining outside the vehicle based on the external precipitation speed and the external precipitation time;

[0056] Step S50: If it is raining outside the vehicle, control the vehicle windows to close.

[0057] After completing the analysis of the external environmental conditions of the vehicle through the external precipitation speed and the external precipitation time, when it is determined that the external environmental conditions are raining, the vehicle windows are automatically closed according to the judgment result. When the driver leaves the vehicle without closing the windows, rainwater can be effectively prevented from entering the interior of the vehicle through the open windows, soaking the items in the vehicle or immersing the circuits and equipment in the vehicle, thereby avoiding affecting the condition of the vehicle and protecting the property safety of the owner.

[0058] See also Figure 2 The second embodiment of the present invention provides an automatic window closing method, which includes the following steps:

[0059] Step S100: Obtain the vehicle's engine status, lock status, and parking brake status;

[0060] Step S101: determining whether the driver has left the vehicle based on the engine status, the vehicle lock status, and the parking brake status;

[0061] The engine status includes a start state and a stop state, the vehicle lock status includes an unlocked state and a locked state, and the handbrake status includes an up state and a down state. The combination of the engine status, the vehicle lock status, and the handbrake status varies when the vehicle is in different driving states, and the driving states include a running state, a parked state, and a stopped state.

[0062] Under normal circumstances, when the engine is in the starting state, the lock is in the locked state, and the handbrake is in the lowered state, the vehicle is in the running state, and the driver has not left the vehicle; when the engine is in the starting state, the lock is in the locked state, and the handbrake is in the pulled state, the vehicle is in the parked state, and the driver has not left the vehicle; when the engine is in the stopping state, the lock is in the unlocked state, and the handbrake is in the pulled state, the vehicle is in the parked state, and the driver has not left the vehicle. However, when the engine is in the stopping state, the lock is in the locked state, and the handbrake is in the pulled state, the vehicle is also in the parked state, but the driver has left the vehicle. It is understandable that the accuracy of the judgment can be further improved by continuing to obtain the brake status, etc.

[0063] Step S102: If the driver is in a state of leaving the vehicle, obtaining the window opening of the vehicle, and comparing the window opening with an opening threshold;

[0064] Step S103: If the window opening is greater than the opening threshold, determining that the window is in an open state;

[0065] Preferably, the opening threshold is 3-5%. The window opening is the opening of any window of the vehicle. Generally, a vehicle has four side windows and one sunroof. When the driver leaves the vehicle, the window openings of all windows are obtained and compared with the opening threshold respectively.

[0066] During the comparison, if the window opening of any window is greater than the opening threshold, it is determined that the window state of the vehicle is open, and a subsequent window closing determination is required.

[0067] Step S104: if the window is in the open state, obtaining the external precipitation speed and external precipitation time of the vehicle;

[0068] Step S105: comparing the external precipitation speed with the rain speed threshold to complete a rainfall determination;

[0069] Preferably, the external precipitation speed and the external precipitation time are obtained by a sensor. The sensor detects rainfall once at a detection interval of 10 to 12 seconds. If the sensor detects precipitation, a rainfall determination is performed. The external precipitation speed refers to the rate at which rainwater contacts the rain sensor. If the external precipitation speed is greater than a preset rain speed threshold, a rainfall determination is made.

[0070] Step S106: determining whether the external precipitation time exceeds a limited time, so as to complete a secondary rainfall determination;

[0071] Step S107: completing the first rainfall determination and the second rainfall determination to complete the rainfall state determination outside the vehicle;

[0072] It is understandable that the sensor can detect precipitation in a variety of situations, including accidental human spillage or the passing of a sprinkler truck. After the first determination of a rainfall state, the second rainfall determination is performed. The sensor begins timing and counts the duration of the rainfall. The sensor's continuous statistical time interval is 1 to 2 seconds, that is, the timing starts from the last time precipitation was detected. If precipitation is detected again within 1 to 2 seconds, the count continues as the external precipitation time. When the external precipitation time exceeds the specified time, a second determination is made as a rainfall state. Preferably, the specified time is 10 to 15 seconds. If both the first and second rainfall determinations indicate a rainfall state, it is considered that the vehicle is in a rainfall state.

[0073] Step S108: If it is raining outside the vehicle, obtain the status of the people inside the vehicle and determine whether there is no one inside the vehicle;

[0074] Step S109: If the interior of the vehicle is unoccupied, controlling the vehicle windows to close;

[0075] In some cases, after the driver's leaving status is determined, there may still be other people such as children or the elderly staying in the car. If the windows are closed directly at this time, the stranded people may be easily trapped inside the vehicle. If the detention time is too long, it may easily lead to safety hazards for the stranded people. Therefore, when executing the step of turning off the car lights, it is necessary to determine whether the interior of the vehicle is unoccupied. If so, the windows will be closed.

[0076] Step S110: If the outside of the vehicle is not in a rainy state, an external wind speed signal of the vehicle is obtained, and rainfall prediction is performed based on the external wind speed signal.

[0077] Generally, if rain is about to fall, the wind speed will be stronger than normal. If, after completing the first and second rainfall determinations, no rainfall is determined, then the vehicle is deemed to be outside a non-raining state. At this point, an external wind speed signal is obtained to determine whether it exceeds a preset wind speed. If so, the vehicle obtains weather information for the day. If the external wind speed signal exceeds the preset wind speed, then the vehicle determines that rain is likely. A rainfall forecast is generated based on the weather information for the day, and a window closing time is preset for the vehicle. The weather information for the day includes weather information for various time periods of the day. If a time point in the weather information indicates rain, that time point is preset as the window closing time for the vehicle. As can be understood, the vehicle windows will close upon reaching the window closing time. Preferably, the vehicle's window closing information and the preset information of the vehicle's window closing time can be transmitted to the driver's mobile phone app through the cloud to realize the notification function. The driver can also stop the execution operation through the mobile phone app, which effectively improves the degree of automation of window closing.
