[0044] It should also be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the objects used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those shown or described.

[0045] It should be noted that fuel cell vehicles have the advantages of being pollution-free, clean and environmentally friendly. The only product of the fuel cell system is water. In traditional fuel cell vehicles, the waste water generated by the fuel cell system is usually discharged directly into the environment, resulting in a waste of water resources. If the ambient temperature is low, the discharged water can easily cause road icing, which in turn poses a safety hazard to vehicle road driving.

[0046] With the development of technology, in order to avoid the waste of water resources, some fuel cell vehicles are equipped with a residual water collection system to recycle the waste water generated by the fuel cell system. However, the water storage capacity of the on-board residual water collection system is limited, and the relevant technology has not reasonably designed the residual water collection method, resulting in poor working efficiency of the residual water collection system.

[0047] Based on this, an embodiment of the present application provides a method for collecting residual water in a fuel cell vehicle, so that to a certain extent, the residual water collection system can be controlled to collect residual water according to the target water demand of the vehicle, so that the water storage capacity in the residual water collection system can better meet the vehicle needs, thereby improving the working efficiency of the residual water collection system.

[0048] The residual water collection method for a fuel cell vehicle according to an embodiment of the present application will be described below with reference to specific drawings.

[0049] See also Figure 1 , showing a structural block diagram of a residual water collection system for a fuel cell vehicle according to an embodiment of the present application.

[0050] like Figure 1 As shown, the residual water collection system of the embodiment of the present application includes a water storage tank, which is used to collect filtered rainwater and / or wastewater generated by the fuel cell system; in addition, the water stored in the water storage tank can be used by various water systems, such as the water purification system for humidifying the passenger compartment and drinking, the washing system for cleaning the vehicle camera, glass windows, and lights, and the cooling system for spraying cooling the heat dissipation device of the fuel system. The following takes the above-mentioned residual water collection system of a fuel cell vehicle as an example to illustrate the residual water collection method of a fuel cell vehicle below.

[0051] See also Figure 2 , showing a flow chart of a method for collecting residual water in a fuel cell vehicle according to an embodiment of the present application.

[0052] like Figure 2 As shown, according to the first aspect of the embodiment of the present application, a method for collecting residual water in a fuel cell vehicle is provided, the fuel cell vehicle comprises a residual water collection system and multiple water use systems, and the method includes but is not limited to:

[0053] Step S1. Acquire a target driving path of the vehicle and a plurality of water use impact data in the target driving path;

[0054] It can be understood that the target driving route of the vehicle can be obtained by planning the route based on the destination that the vehicle intends to reach using tools such as maps. For example, if the vehicle intends to go from point A to point B, the driving route between points A and B can be planned using the on-board map tool, such as points ACDB.

[0055] It is understandable that when a vehicle is driving, different factors may cause different water demand of the vehicle. For example, water consumption influencing data include weather data, environmental data, road condition data and working condition data. Among them, weather data include sunny days, strong winds, snowy days, rainy days, haze and other data, and the above weather data can be obtained through third-party platforms such as meteorological websites; environmental data include hot, dry, humid, cold and other data, and the above environmental data can also be obtained through third-party platforms such as meteorological websites; road condition data include cement roads, asphalt roads, muddy roads, etc., and the road condition data can be obtained from third-party tools such as maps; working condition data include urban roads, congested working conditions, highways, suburbs, etc., and the working condition data can also be obtained from third-party tools such as maps.

[0056] In addition, when the surplus water collection system includes a water purification system, and the water purification system can be used to generate drinking water, the water use impact data may also include historical water drinking data of passengers, etc.

[0057] Step S2. Determine the target water demand of the multiple water use systems according to the target driving route and the multiple water use impact data;

[0058] Since different water use impact data may have different impacts on the water consumption of the vehicle in the target driving route, for example, when the environmental data in the target driving route is hot, the vehicle has a greater demand for water for cooling, humidification, etc. during driving; and for another example, when the road condition data in the target driving route is muddy, the vehicle has a greater demand for water for washing, etc. during driving. Therefore, the embodiment of the present application can clearly define the target required water volume when the vehicle is running according to the target driving route.

[0059] It can be understood that based on the functional mapping relationship between the target driving path and the target water demand, the target water demand of the water use system can be determined. Specifically, by simulating and calculating the influence coefficient of each water use influencing data on the target water demand, each influence coefficient can be determined, and then the target driving path can be weighted based on the influence coefficient to obtain the target water demand. For example: through simulation and collection and analysis of vehicle data in actual areas, the water use influence coefficients of weather, environment, road conditions and working conditions corresponding to the vehicle's driving path are fitted, such as: weather influence coefficients a1, a2, a3... (influence coefficients corresponding to sunny, rainy, snowy and other weather conditions), environmental influence coefficients b1, b2, b3... (influence coefficients corresponding to hot, dry and humid environments), road condition coefficients c1, c2, c3... (influence coefficients corresponding to road conditions such as cement roads, asphalt roads and muddy roads), working condition coefficients d1, d2, d3... (influence coefficients corresponding to working conditions such as urban roads, congestion and highways). Therefore, the target water demand of the vehicle in this driving route can be predicted based on the road condition and working condition coefficients of the vehicle's driving route combined with the weather environment coefficient at that time.

[0060] In some embodiments, the target driving route includes at least one target driving section, and determining the target water demand of the multiple water use systems according to the target driving route and the multiple water use impact data includes:

[0061] Step S21. For each target driving section, obtain the influence coefficient of each water use influence data corresponding to the target driving section, perform weighted calculation on the target driving section based on each influence coefficient, and obtain the required water volume of the section;

[0062] Step S22: Obtain the target required water volume in the target driving route according to the required water volume of each target driving section.

[0063] For example, from A to B, there are three target driving sections, AC, CD, and DB, and the mileage of each section is X1, X2, and X3 respectively. In the AC section, the weather is sunny, the environment is humid, the road condition is asphalt section, and the working condition is high-speed; in the CD section, the weather is rainy, the environment is humid, the road condition is asphalt section, and the working condition is high-speed; in the DB section, the weather is sunny, the environment is hot, the road condition is muddy section, and the working condition is urban road.

[0064] Therefore, based on the above influence coefficient, it can be calculated:

[0065] Y1=a1*b3*c2*d3*X1, Y1 represents the water demand of the AC section;

[0066] Y2=a2*b3*c2*d3*X2, Y2 represents the water demand of the road section CD;

[0067] Y3=a1*b1*c3*d1*X3, Y3 represents the road section water demand of DB section;

[0068] Y=Y1+Y2+Y3, where Y represents the target required water volume of the target driving route.

[0069] Step S3. When the vehicle is running along the target driving route, the residual water collection system is controlled to collect rainwater and / or wastewater generated by the fuel cell system so that the total water storage capacity of the residual water collection system in the target driving route is greater than or equal to the target required water volume.

[0070] It is understandable that in the process of controlling the residual water collection system to collect rainwater and / or wastewater generated by the fuel cell system, both can be collected at the same time, or one of the two can be collected. For example, when the fuel cell system stops working, if it is rainy, rainwater can be collected; if the fuel cell system is running, if it is sunny, wastewater generated by the fuel cell can be collected; if it is rainy, rainwater and wastewater generated by the fuel cell system can be collected at the same time. Of course, when rainwater and wastewater generated by the fuel cell system can be collected at the same time, the priority of the two can also be set, such as giving priority to collecting wastewater generated by the fuel-electric system.

[0071] It is understandable that due to the limited water storage capacity of the residual water collection system on the vehicle, for example, the maximum water storage capacity of the above-mentioned water tank is 10L, and the target water demand of the vehicle is 15L, that is, the maximum water storage capacity of a water tank cannot meet the target water demand of the vehicle. Therefore, in the embodiment of the present application, when the vehicle is running according to the target driving path, the residual water collection system is controlled to collect rainwater, so that the total water storage capacity of the residual water collection system in the target driving path is greater than or equal to the target water demand, for example, a total of 20L of water is collected during the entire driving process, thereby being able to meet the water demand of the entire vehicle.

[0072] Based on the above disclosed content, the fuel cell vehicle of the embodiment of the present application includes a residual water collection system and multiple water use systems, and obtains the target driving path of the vehicle and multiple water use impact data in the target driving path; determines the target water demand of multiple water use systems according to the target driving path and the multiple water use impact data; in the process of the vehicle running according to the target driving path, controls the residual water collection system to collect rainwater and / or wastewater generated by the fuel cell system, so that the total water storage capacity of the residual water collection system in the target driving path is greater than or equal to the target water demand. Thus, the target water demand of the vehicle in the target driving path is predicted using multiple water use impact data, and then the residual water collection system is controlled to collect residual water according to the target water demand, so that the water storage capacity in the residual water collection system can better meet the vehicle needs, and the working efficiency of the residual water collection system is improved.

[0073] In some embodiments, after determining the target water demand of the plurality of water use systems, the method further includes:

[0074] If the target required water volume is less than the current water storage volume of the residual water collection system, then while the vehicle is running along the target driving route, the residual water collection system is controlled to collect and discharge rainwater and / or wastewater generated by the fuel cell system, so that at the target moment when the vehicle completes the target driving route, the water storage volume of the residual water collection system is greater than or equal to a preset threshold.

[0075] It can be understood that if the target water demand during the vehicle's driving is less than the current water storage capacity of the residual water collection system, the water storage and drainage functions of the residual water collection system can be turned on at the same time, and the water storage capacity in the residual water collection system can be kept greater than or equal to about 90%, so as to avoid the situation where there is no water available during the next use of the vehicle due to the fact that no residual water was stored during the last use.

[0076] In some embodiments, when controlling the residual water collection system to collect rainwater and / or wastewater generated by the fuel cell system, the method further includes:

[0077] Step S31. Obtaining the ambient temperature of the current driving section of the vehicle and the current water storage capacity of the residual water collection system;

[0078] Step S32. If the ambient temperature is less than or equal to the preset temperature, and the current water storage capacity reaches the water storage capacity threshold of the residual water collection system, the residual water collection system is controlled to stop collecting rainwater and / or wastewater generated by the fuel cell system, and the wastewater generated by the fuel cell system is atomized and discharged.

[0079] It is understandable that when the ambient temperature is low, if the wastewater generated by the fuel cell system is discharged directly into the environment, it may cause road icing, thereby posing a safety hazard; based on this, in the embodiment of the present application, when the ambient temperature is low, if the water storage capacity of the residual water collection system reaches a threshold value, for example, 100%, the wastewater generated by the fuel cell system is atomized and discharged through the drain outlet of the vehicle tailgate, thereby avoiding situations such as road icing caused by direct discharge of wastewater.

[0080] In some embodiments, during the process of the vehicle running according to the target driving path, the method further includes:

[0081] Step S4. Detecting the environmental information of the current driving section of the vehicle;

[0082] The environmental information may refer to environmental climate information, such as dry, hot, humid and other climate information.

[0083] Step S5. Determine the water use priority among the water use systems according to the environmental information of the current driving section.

[0084] In some embodiments, the multiple water use systems include a water purification system, a washing system, and a cooling system, and determining the water use priority among the water use systems according to the environmental information of the current driving section includes:

[0085] Step S51. If the humidity information of the current driving section is less than or equal to the humidity threshold, the water purification system has a higher priority than the washing system and the cooling system;

[0086] For example, when the vehicle is traveling in a dry environment, the vehicle prioritizes vehicle humidification and water storage for crew members' drinking water. Based on the vehicle's navigation driving distance, the vehicle retains the corresponding amount of water required for the journey, and the remaining water is used according to driving needs.

[0087] Step S52: If the temperature information of the current driving section is greater than or equal to the temperature threshold, the cooling system has a higher priority than the water purification system and the washing system;

[0088] For example, when the vehicle is traveling in a hot environment, the vehicle prioritizes cooling the vehicle's fuel and electrical systems and reserving water for crew members' drinking water. The required amount of water is retained based on the vehicle's navigation distance, and the remaining water is used according to driving needs.

[0089] Step S53: If the visibility information of the current driving section is less than or equal to the visibility threshold, the washing system has a higher priority than the water purification system and the cooling system.

[0090] For example, when a vehicle is traveling in a foggy or dusty environment, the vehicle prioritizes reserving the water required for window glass washing, headlight washing, etc., and retains the required amount of water based on the vehicle's navigation driving distance, and the remaining water is used according to driving needs.

[0091] Therefore, the embodiment of the present application can set the water use priority of each water use system according to the vehicle driving environment, so as to give priority to the water use system with the highest priority, and the remaining water can be allocated according to driving needs to improve the utilization efficiency of the water storage capacity of the residual water collection system.

[0092] In some embodiments, when controlling the residual water collection system to collect rainwater and / or wastewater generated by the fuel cell system, the method further includes:

[0093] Water level monitoring of the water storage tank of the residual water collection system:

[0094] When the water level is less than the lowest water level line α, the residual water collection system is controlled to stop supplying water to the water-using system;

[0095] When the water level is greater than the highest water level line β, the residual water collection system is controlled to stop collecting residual water, and the water is atomized and discharged out of the vehicle through the water outlet under the rear tailgate of the vehicle to avoid direct discharge of water in cold weather, which may cause safety hazards due to icing of the road surface.

[0096] When the water level of the water tank is between the highest water level line and the lowest water level line, the water supply strategy of the water tank to each water use system can be;

[0097] Humidification / dehumidification of passenger compartment: When the humidity monitored by the air humidity sensor in the cockpit is less than the minimum value of air humidity γ1, the user can be reminded through the central control screen and / or voice broadcast that the humidity in the cabin is low and it is recommended to turn on the humidification function. The user can control the residual water collection system to supply water to the purified water system through the central control screen or voice interaction to humidify the passenger compartment. Specifically, the water output from the water storage tank passes through the first two purification systems (filtering visible objects such as mud, rust, etc.; adsorbing colloids in the water and removing foreign colors and odors) and the atomizer, and humidifies the passenger compartment from the air outlet of the air conditioner. When the humidity monitored by the air humidity sensor in the cabin is greater than the preset humidity value θ, humidification is automatically stopped. When the humidity monitored by the air humidity sensor in the cockpit is greater than the maximum value of air humidity γ2, the user can be reminded through the central control screen and / or voice broadcast that the humidity in the cabin is high and it is recommended to turn on the dehumidification function. The user can control the dehumidification of the passenger compartment through the central control screen or voice interaction, and store the water collected by dehumidification in the residual water collection system.

[0098] Drinking water in the passenger compartment: There is a water outlet in the cockpit, which is filtered four times through the filtration system (filtering out visible objects such as mud, rust, etc.; absorbing colloids in the water and removing foreign colors and odors; removing bacteria, heavy metals, scale and other harmful substances). Among them, room temperature water can be drunk directly. If heating is required, it can be heated through pipes to avoid repeated heat preservation of boiling water. In addition, the heating pipe uses non-metallic glass heating material to avoid the precipitation of heavy metal ions during heating.

[0099] Washing: The washing system includes a washing pot. When the liquid level in the washing pot is lower than the minimum liquid level of the washing pot, the water in the water tank is input into the washing pot through a pipe. When the visibility of the on-board camera is insufficient and the vehicle's lights are dim at night, the user can control the washing pot through the central control screen to flush and clean the camera, vehicle lighting system, etc.; or, when the vehicle window glass is blurred, the user can control the washing pot through the central control screen to clean the vehicle window glass.

[0100] Cooling: Connect the water tank to the cooling system of the fuel-electric system. When the temperature of the fuel-electric system is higher than the first threshold value δ, the radiator fan is turned on to remove excess heat. At this time, the temperature of the fuel-electric system is continuously monitored. When the temperature is higher than the second threshold value δ1 (δ1>δ), the fan heat dissipation cannot meet the driving needs of the vehicle. The heat dissipation circulation valve is opened, and the water in the water tank is circulated to the front end of the radiator, sprayed onto the radiator through the valve arranged at the front end, and cooperates with the fan to accelerate the evaporation of water to assist in completing the heat dissipation of the battery stack.
