Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a vehicle snow melting method, system, device, vehicle and storage medium. Background Art

[0002] Winter driving in cold regions presents a challenge for many. Sudden heavy snowfalls at night can lead to thick snow accumulation on the windshield, frozen windshield wipers, and even frozen hidden door handles. Clearing the snow from the vehicle the next day is time-consuming and labor-intensive. Forcing the wipers into action can cause them to deform or overheat, damaging the motor. Furthermore, failure to defrost the wiper wipers in time can delay travel. Alternatively, encountering snowy roads while traveling can lead to scattered snow on the windshield, impairing the driver's vision. While traditional wipers can improve visibility to a certain extent, they often struggle to achieve optimal results in extreme weather (such as heavy snow). Ice debris from scraping can even pose a serious safety hazard. Furthermore, hidden door handles are impractical in northern winters and are difficult to open due to icy conditions.

[0003] The current snow melting and defrosting strategies include manual snow removal and spraying of snow melting agents, but manual snow removal is time-consuming, labor-intensive and inefficient.

[0004] It can be seen that how to improve the efficiency of clearing snow from the front windshield of a vehicle is a technical issue worthy of attention. Summary of the Invention

To facilitate understanding of the embodiments of this application, the application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0108] In order to solve the technical problem of how to improve the efficiency of clearing snow from the front windshield of a vehicle in the prior art, the present application provides a vehicle snow melting method, system, device, vehicle and storage medium, which can improve the efficiency of clearing snow from the front windshield of a vehicle.

[0109] Figure 1A flow chart of a vehicle snow melting method provided in an embodiment of the present application. This method can be applied to one or more electronic devices such as vehicles (such as smart vehicles, smart cars), smart phones, laptops, desktop computers, portable computers, servers, etc. In addition, the execution subject of this method can be hardware or software. When the above-mentioned execution subject is hardware, the execution subject can be one or more of the above-mentioned electronic devices. For example, a single electronic device can execute this method, or a plurality of electronic devices can cooperate with each other to execute this method. When the above-mentioned execution subject is software, this method can be implemented as multiple software or software modules, or as a single software or software module. No specific limitation is made here.

[0110] like Figure 1 As shown, the method specifically includes:

[0111] Step 101: Detect a first snow thickness on a front windshield of a vehicle.

[0112] In this embodiment, the first snow thickness may be the snow thickness on the front windshield of the vehicle.

[0113] In practice, the first snow thickness on the front windshield of the vehicle can be detected by at least one of photoelectric, ultrasonic, and lidar technologies.

[0114] Step 102: Determine a first strategy for spraying a snow-melting agent based on a first snow thickness.

[0115] In this embodiment, the first strategy may be a strategy of spraying snow melting agent based on the first snow thickness.

[0116] Here, different snow thicknesses can correspond to different snow-melting agent spraying strategies.

[0117] As an example, multiple (e.g., four) thickness ranges may be pre-set, and each thickness range may correspond to a strategy for spraying deicing agent. Thus, a first strategy for spraying deicing agent may be determined by determining the strategy corresponding to the thickness range that includes the first snow thickness.

[0118] In addition, the strategies for spraying snow-melting agents (including the first strategy) may differ in terms of the amount, number of times, frequency, and interval length of the snow-melting agents.

[0119] Step 103: spray snow melting agent on the front windshield according to the first strategy.

[0120] In this embodiment, after the first strategy is determined, the snow melting agent may be sprayed onto the front windshield according to the first strategy.

[0121] Step 104 : After spraying the snow melting agent on the front windshield, determine whether the vehicle status information meets the vehicle wiper activation condition.

[0122] In this embodiment, the status information may represent at least one of the following states of the vehicle: thickness of snow, temperature of the windshield, hardness of obstacles covering the windshield, whether the wiper strips can move relative to the windshield, etc.

[0123] The wiper start condition can be used to determine whether to start the wipers.

[0124] As an example, when the status information includes the thickness of snow, the wiper activation condition may include: the snow thickness is less than or equal to a preset thickness threshold.

[0125] As another example, when the status information includes whether the wiper rubber strip and the front windshield can move relative to each other, the wiper start condition may include: whether the wiper rubber strip and the front windshield can move relative to each other.

[0126] Step 105: When the status information meets the wiper start condition, control the vehicle's wipers to wipe the front windshield.

[0127] In this embodiment, if the status information meets the wiper start condition, then the wipers can be further turned on to control the vehicle's wipers to wipe the front windshield.

[0128] In some optional implementations of this embodiment, the following method can be used to determine the first strategy for spraying snow-melting agent based on the first snow thickness:

[0129] Based on the first snow thickness, target parameters for spraying the snow melting agent are determined.

[0130] The target parameter includes at least one of the number of times and the amount of use.

[0131] On this basis, the following methods can be adopted to spray snow melting agent on the front windshield according to the first strategy:

[0132] Spray snow melting agent onto the front windshield according to target parameters.

[0133] It is understood that in the above optional implementation, the number of times and amount of de-icing agent spraying can be determined based on different first snow thicknesses, and the de-icing agent can then be sprayed on the front windshield according to the determined number of times and amount of de-icing agent spraying. This allows the de-icing agent spraying strategy to be more closely aligned with the current snow thickness on the vehicle's front windshield, thereby enabling more efficient use of the de-icing agent and reducing environmental pollution.

[0134] In some optional implementations of this embodiment, after spraying snow melting agent on the front windshield, determining whether the vehicle status information meets the vehicle wiper activation condition may specifically include:

[0135] After spraying the snow melting agent on the front windshield is completed and a preset time interval has elapsed, it is determined whether the vehicle status information meets the vehicle's wiper start-up conditions.

[0136] The preset duration may be a pre-set duration, such as 5 minutes, 10 minutes, etc.

[0137] It is understood that in the above optional implementation, after the spraying of the snow-melting agent on the front windshield is completed and a preset time interval has elapsed, the vehicle status information can be further determined to determine whether it meets the vehicle's wiper activation conditions. Therefore, since the snow-melting effect can be more accurately determined after the preset time interval, the timing of activating the wipers can be more accurately determined.

[0138] In some optional implementations of this embodiment, after spraying snow melting agent on the front windshield, determining whether the vehicle status information meets the vehicle wiper activation condition may specifically include:

[0139] The first step is to detect a second snow thickness on the front windshield of the vehicle after spraying the snow melting agent on the front windshield.

[0140] The second snow thickness may be: the snow thickness on the front windshield of the vehicle after the snow-melting agent is sprayed on the front windshield.

[0141] The second step is to determine the difference between the first snow thickness and the second snow thickness.

[0142] In the third step, when the difference is less than or equal to the preset threshold, the snow melting agent is sprayed on the front windshield according to the first strategy.

[0143] It can be understood that in the above optional implementation method, if the amount of snow removed after spraying the snow-melting agent is small (that is, the above difference is less than or equal to the preset threshold), then the snow-melting agent can be directly sprayed on the front windshield again according to the first strategy to melt the snow, thereby improving the efficiency of removing snow.

[0144] In some application scenarios of the above optional implementation manner, after determining the difference between the first snow thickness and the second snow thickness, the following steps may be further performed:

[0145] In the first step, when the difference is greater than a preset threshold, a second strategy of spraying snow melting agent is determined based on the second snow thickness.

[0146] The second strategy may be a strategy of spraying snow-melting agent based on the second snow thickness.

[0147] Here, different snow thicknesses can correspond to different snow-melting agent spraying strategies.

[0148] As an example, multiple (e.g., four) thickness ranges may be pre-set, and each thickness range may correspond to a strategy for spraying deicing agent. Thus, the second strategy for spraying deicing agent may be determined by determining the strategy corresponding to the thickness range that includes the second snow thickness.

[0149] In addition, the strategies for spraying snow-melting agents (including the second strategy) may differ in terms of the amount, number of times, frequency, and interval length of the snow-melting agents.

[0150] The second step is to spray snow melting agent on the front windshield according to the second strategy.

[0151] Here, after the second strategy is determined, the snow melting agent may be sprayed onto the front windshield according to the second strategy.

[0152] It can be understood that in the above application scenario, if the amount of snow removed after spraying the snow-melting agent is large (that is, the above difference is greater than the preset threshold), then the second strategy matching the current snow thickness can be re-determined, and then the snow-melting agent can be sprayed on the front windshield according to the second strategy to melt the snow. In this way, the spraying strategy of the snow-melting agent can be more closely matched with the current snow thickness on the front windshield of the vehicle, so that the snow-melting agent can be used more reasonably, thereby reducing environmental pollution.

[0153] In some optional implementations of this embodiment, the status information includes at least one of the following:

[0154] The first item is the thickness of snow on the vehicle's front windshield.

[0155] The second item is whether the wiper strips and the front windshield can move relative to each other.

[0156] It can be understood that in the above optional implementation, whether to start the vehicle's wipers to clear the snow can be determined by at least one of the thickness of the snow on the front windshield and whether the rubber strip and the front windshield can move relative to each other. In this way, the timing of starting the wipers can be determined more accurately, thereby improving the efficiency of snow cleaning.

[0157] In some optional implementations of this embodiment, the following methods may be used to control the vehicle's wipers to wipe the front windshield:

[0158] The first step is to check whether there is snow on the vehicle's windshield.

[0159] Here, whether there is snow on the windshield can be determined by detecting the thickness of the covering material of the windshield. Alternatively, whether there is snow on the windshield can be determined by detecting the quality of the covering material of the windshield.

[0160] The second step is to control the vehicle's wipers to wipe the front windshield at the lowest speed when there is snow on the front windshield.

[0161] The minimum speed may be the minimum speed at which the wipers can be started.

[0162] It is understood that in the above optional implementation, if the status information meets the wiper activation condition and there is snow on the front windshield, the vehicle's wipers can be controlled to wipe the front windshield at the lowest speed. In this way, damage to the wipers can be reduced or even avoided.

[0163] The vehicle snow-melting method provided in an embodiment of the present application can detect a first snow thickness on the front windshield of the vehicle, then determine a first strategy for spraying a snow-melting agent based on the first snow thickness, then spray the snow-melting agent on the front windshield according to the first strategy, then determine whether the vehicle's status information meets the vehicle's wiper activation conditions after spraying the snow-melting agent on the front windshield, and finally, if the status information meets the wiper activation conditions, control the vehicle's wipers to wipe the front windshield. In this way, the vehicle's wipers can assist in clearing snow from the vehicle's front windshield, thereby improving the efficiency of clearing snow from the vehicle's front windshield.

[0164] Figure 2 This is a flow chart of another vehicle snow melting method provided in an embodiment of the present application. Figure 2 As shown, the method specifically includes:

[0165] Step 201: Detect the ambient temperature of the vehicle's environment.

[0166] In this embodiment, the ambient temperature may be the temperature of the environment in which the vehicle is located.

[0167] Step 202 : When the ambient temperature is less than or equal to a preset temperature threshold, detect a first snow thickness on the front windshield of the vehicle.

[0168] In this embodiment, the preset temperature threshold may be a pre-set temperature, such as 5 degrees Celsius.

[0169] In addition, step 202 is Figure 1 Step 101 in the corresponding embodiment is basically the same and will not be described again here.

[0170] Step 203: Determine a first strategy for spraying a snow-melting agent based on the first snow thickness.

[0171] In this embodiment, step 203 and Figure 1 Step 102 in the corresponding embodiment is basically the same and will not be described again here.

[0172] Step 204 : spraying snow melting agent on the front windshield according to the first strategy.

[0173] In this embodiment, step 204 and Figure 1 Step 103 in the corresponding embodiment is basically the same and will not be described again here.

[0174] Step 205 : After spraying the snow melting agent on the front windshield, determine whether the vehicle status information meets the vehicle wiper activation condition.

[0175] In this embodiment, step 205 and Figure 1 Step 104 in the corresponding embodiment is basically the same and will not be described again here.

[0176] Step 206: When the status information meets the wiper start condition, control the vehicle's wipers to wipe the front windshield.

[0177] In this embodiment, step 206 and Figure 1 Step 105 in the corresponding embodiment is basically the same and will not be described again here.

[0178] Optionally, when the ambient temperature is greater than the above-mentioned preset temperature threshold, there is no need to detect the first snow thickness on the front windshield of the vehicle.

[0179] It should be noted that, in addition to the above contents, this embodiment may also include Figure 1 The corresponding technical features described in the corresponding embodiments are realized Figure 1 For details on the technical effects of the vehicle snow melting method shown, please refer to Figure 1 For the sake of brevity, the relevant description will not be repeated here.

[0180] The vehicle snow melting method provided in the embodiment of the present application can detect the first snow thickness on the front windshield of the vehicle only when the ambient temperature is low. When the ambient temperature is high, there is no need to detect the first snow thickness on the front windshield of the vehicle. Therefore, the frequency of snow thickness detection can be reduced, thereby reducing vehicle energy consumption.

[0181] The following is an illustrative description of the embodiments of the present application, but it should be noted that the embodiments of the present application may have the features described below, but the following description does not constitute a limitation on the scope of protection of the embodiments of the present application.

[0182] Winter driving in cold regions presents a challenge for many. Sudden heavy snowfalls at night can lead to thick snow accumulation on car windshields, frozen windshield seals, and even frozen hidden door handles. Clearing the snow from the car the next day is time-consuming and labor-intensive. Forcing the wipers on can cause them to deform or overheat, damaging the motor. Furthermore, delaying the wiper seals can delay travel. Alternatively, when encountering snowy roads while traveling, snow can scatter on the windshield, obscuring the driver's field of vision. While traditional wipers can improve visibility to some extent, they often struggle to achieve optimal results in extreme weather (such as heavy snow). Ice debris from scraping can even pose a serious safety hazard. Furthermore, hidden door handles are difficult to open due to freezing.

[0183] Environmental protection has become a global concern. Using large amounts of deicing agents can cause environmental pollution, and traditional washing systems often result in over- or under-washing.

[0184] Current snow melting and defrosting strategies include heating the windshield, manual snow removal and spraying of snow melting agents, etc. However, all of these have certain disadvantages. Glass heating consumes a lot of energy, and the cost of heating glass is relatively high, while manual snow removal is time-consuming and labor-intensive.

[0185] With the development of intelligent technology, especially in the automotive field, functions such as smart wipers and automatic snow melting have gradually become hot spots in the market. Users have higher requirements for intelligent and humanized driving experience. Therefore, this solution proposes a multifunctional system with intelligent snow melting and intermittent spraying function.

[0186] This solution proposes an integrated intelligent system for snow melting and wiper cleaning, which can solve the problems of the existing car's front windshield wiper defrosting and snow removal system being difficult and time-consuming to clean in a heavy snowy environment in winter, the difficulty in defrosting and removing snow from door handles (especially hidden door handles), the inability to select the wiper snow melting function while driving on snowy days, the serious environmental pollution caused by the use of large doses of snow melting agent, and the delay in snow removal caused by remote operation, which requires users to wait.

[0187] See also Figure 3 , this scheme achieves the above purpose through the following technical solutions:

[0188] A multifunctional intelligent snow melting and windshield wiper and wash system integrates the snow melting system for the front windshield and door handles, while the washing system is only used for normal wiper wiping. The overall system includes a perception system (also known as the detection module), a decision-making system (also known as the control module), and an actuator (also known as the execution module). The perception system components include rain and light sensors, external temperature sensors, and snow sensors for detecting environmental parameters such as snow volume and temperature. The decision-making system includes a body control unit for signal reception, processing, and transmission. The actuator includes a liquid reservoir, switch, relay, solenoid valve, washer pump, fluid pipeline, nozzle, and front windshield wipers, which are used to achieve the snow melting and washing functions.

[0189] like Figure 4 As shown, the rain sensor and snow sensor are electrically connected to the vehicle body control unit, which is in turn electrically connected to the relay, which is in turn electrically connected to the solenoid valve. The liquid reservoir is divided into two storage areas: a first storage area 1 and a second storage area 2 for snowmelt and washing liquid. Two liquid pipelines 9 extend from the bottom of each of the two storage areas of the liquid reservoir 3 and are fixedly connected to the water inlets of the first and second control valves 4 and 5 via quick connectors. The first and second control valves 4 and 5 are connected in parallel, with their outlets connected to the water inlet of a one-way flow pump 7 via a tee 6. The liquid pipeline 9 at the door handle end is connected to the windshield washer liquid pipeline 9 via the tee 6. A second spray device is located at the bottom of the rearview mirror 10 mounting base to prevent interference with the foldable rearview mirror. A rearview mirror solenoid valve 8 is installed at the front end of the door handle end liquid pipeline 9. The one-way flow pump 7 is connected to the first spray device 14 at the front windshield via a liquid pipeline 9.

[0190] Optionally, the liquid pipeline of the snow melting agent and the detergent having a common three-way pipe (including the three-way pipe, the first control valve and the second control valve) can be replaced by a two-position three-way solenoid valve; similarly, the three-way pipe and the solenoid valve at the door handle end can be replaced by a two-position two-way solenoid valve.

[0191] Optionally, the second spray device at the base of the rearview mirror adopts a hidden arrangement, and a mounting base is provided on the base. It is not limited to a snap-on fixation, and a servo can be provided to adjust the nozzle angle to ensure that the installation angle of the first spray device is facing the hidden door handle.

[0192] Optionally, the switch for manually selecting the two modes can be selected by button type, knob type, screen touch type, or voice type.

[0193] Optionally, the switch is not limited to a single-pole double-throw analog switch and an interlock circuit.

[0194] Here we focus on the automatic and manual switching of the snow melting and washing system. Initially, the second spraying device is in the washing mode, that is, normally open, and the snow melting system is normally closed.

[0195] First, in automatic snow melting and washing mode, an outdoor temperature sensor collects the temperature (also known as the ambient temperature). When the outdoor temperature reaches 5°C (the preset temperature threshold), a snow sensor (using photoelectric, ultrasonic, or lidar technology) is triggered to measure the snow thickness. The sensor sends a signal to the vehicle body control unit, which converts the received signal into specific parameter information and then feeds it back to the control chip for processing. The vehicle body control unit analyzes and processes the changes in snow thickness on the vehicle's front windshield. Based on a calibrated adjustment algorithm, a snow threshold is set to automatically switch between snow melting and washing modes. After information processing is completed, the snow melting or washing mode is determined, all solenoid valves are initialized to the closed state, and a signal is sent to the relay receiving end of the one-way flow pump 7, the snow melting agent solenoid valve 4, and the rearview mirror solenoid valve 8. This opens the first control valve 4, the rearview mirror solenoid valve 8, and the one-way flow pump 7 to spray the snow melting agent. Simultaneously, the detergent solenoid valve 5 is closed to prevent the snow melting agent liquid from flowing back into the washing end liquid pipeline.

[0196] When the snow is thick and the amount of snow is large, after the first snow melting agent spraying action is completed, several sprayings are carried out continuously. The number of sprayings is calibrated and confirmed according to the thickness of the snow. The number of sprayings is set in a gradient manner for different snow thicknesses. In order to maximize the snow melting effect, for example, 4 gradient cycles can be set. The specific system logic is as follows: Figure 5 As shown. After completing the first cycle of snow melting, wait for a period of time (the effect of the snow melting agent, the level of the snow melting agent dissolution is also calibrated). After the waiting time is reached, the snow amount sensor detects the amount of snow. If the amount of snow does not decrease, the first cycle of snow melting will continue; if the amount of snow decreases, the second cycle of snow melting will be carried out. The second cycle of snow melting will refer to the first cycle and perform the next gradient level of spraying to melt the snow until the amount of snow is lower than the snow amount threshold after detection, especially to ensure that there is no freezing between the rubber strip and the glass and relative movement is possible. At this time, the one-way flow pump 7 is turned off, and after waiting for several minutes, the wiper 15 is started to perform the scraping operation to scrape the melted snow from the front windshield 13. If there is still snow obstacle on the windshield during the scraping process, the wiper scraping speed can be adjusted to the lowest to prevent residual snow from damaging the rubber strip. At the same time, the washing pump is turned on and a certain amount of snow melting agent is continued to be sprayed. After waiting for a period of time, normal scraping is performed. At this time, the snow melting system is turned off and the washing system is restored to normal operation. The wiper speed is gradually restored, as shown. Figure 6 shown.

[0197] Here, a physical switch can be set for manual snow melting and washing mode. Switch S1 is the washing mode. When S1 is closed, KM2 is energized, KM1 is de-energized, and the second control valve 5 and the one-way flow pump 7 work. Switch S2 is the snow melting mode. When S2 is closed, KM1 is energized, KM2 is de-energized, and the first control valve 4, the rearview mirror end solenoid valve 8 and the one-way flow pump 7 work. Therefore, the order of snow melting and washing can be dynamically adjusted according to actual needs. The specific steps are: when the ambient temperature changes, such as entering a snowy area or the amount of snow increases, the snow melting mode can be manually selected. When leaving the corresponding area, it is switched to the normal washing mode. That is, after monitoring the environmental parameters, if the snow melting intensity needs to be increased, the one-way flow pump 7 is started to continuously spray the snow melting agent; at the same time, considering the washing needs, the working time of the washing pump is appropriately turned on or extended. The circuit diagram is as shown Figure 7 shown.

[0198] It should be noted that, in addition to the contents recorded above, this embodiment may also include the technical features described in the above embodiments, thereby achieving the technical effects of the vehicle snow melting method shown above.

It is simple to operate, low cost, and high feasibility. It can significantly improve the car-using experience in the northern winter, making travel freer and safer.
