Description

Technical Field

[0001] The present invention relates to the technical field of vehicle charging and discharging, and particularly to a method, device, vehicle, and storage medium for displaying grid electricity prices. Background Art

[0002] With the popularization of vehicle electrification, the market share of new energy vehicles has been continuously increasing, and the use of charging piles has also increased accordingly. In order to increase the electricity sales during idle time and in idle areas, the charging electricity price often varies in different times and different regions. For example, the electricity price in remote areas is cheaper, and the electricity price at night is cheaper than that during the day. In addition, the vehicle can also obtain benefits by discharging electricity reversely to the charging pile. In order to enable users to fully understand the electricity price, the power grid often displays it on a specified page through an Internet platform, and users can view it by connecting to the network through terminals such as mobile phones. However, this scheme for viewing the electricity price is not intuitive, and users often do not know the web address for viewing the electricity price, resulting in users not understanding the electricity price. This is uneconomical for both the power grid power consumption and user use, and is not conducive to the balanced use of electric energy. Summary of the Invention

[0003] In view of this, the present invention provides a method, device, vehicle, and storage medium for displaying grid electricity prices to solve the problem of users charging vehicles.

[0004] In a first aspect, the present invention provides a method for displaying grid electricity prices. The method includes: when the vehicle is connected to a charging device, sending an electricity price request to the grid platform; receiving the electricity price information sent by the grid platform in response to the electricity price request; generating a first display scheme based on the electricity price information, where the first display scheme is used to control the lighting effect of a target lamp on the vehicle, and the target lamp is a lamp installed inside or outside the vehicle; and controlling the target lamp on the vehicle to light up based on the first display scheme.

[0005] According to the above technical means, when the vehicle establishes a charging connection with the charging device, it includes two situations: vehicle charging and discharging. The vehicle automatically sends a request to obtain the electricity price to the power grid, so that the electricity price information is transmitted to the vehicle. The vehicle controls the target lamp on the vehicle to light up according to the specified lighting effect scheme in cooperation with the preset first display scheme according to the level of the electricity price, so as to directly remind the user of the grid electricity price intuitively through the lighting effect of the vehicle. Furthermore, the user can select a suitable area or time for charging or discharging according to the level of the electricity price, which not only solves the problem of high charging cost or low discharging income for users, but also can adjust the balance of power grid power consumption, promote more consumption of power grid electricity during idle time, and reduce power consumption when the power grid is short of electricity, significantly improving the economy of vehicle charging.

[0006] In a possible implementation, the method further includes: sending a carbon emission request to a power grid platform; receiving carbon emission data sent by the power grid platform in response to the carbon emission request; and updating the first display scheme based on the carbon emission amount represented by the carbon emission data.

[0007] According to the above-mentioned technical means, in addition to obtaining electricity price information, the vehicle also downloads carbon emission data from the power grid in real time after connecting to the charging pile to indicate the high and low carbon emissions in different areas at different times. It also displays the high and low carbon emissions by controlling the target lights on the vehicle with preset lighting effects. The lighting effects can guide users to choose environmentally friendly charging and discharging time periods for charging or discharging, which can further improve the environmental protection effect of electricity consumption of new energy vehicles.

[0008] In a possible implementation, the method further includes: acquiring the operating state of the vehicle; when the operating state is a stationary state, determining whether the vehicle is in a charging state or a discharging state; generating a second display scheme based on the charging state or the discharging state; and applying the second display scheme to the target lights of the vehicle.

[0009] According to the above technical means, when the vehicle is charging or discharging, different second display schemes can be customized according to the corresponding charging and discharging status, such as plug-in charging, scheduled charging, plug-in discharging, charging power, etc., to be applied to the vehicle's target light. Therefore, the vehicle's target light can not only display information such as electricity prices, but also prompt the vehicle's charging and discharging status, guiding users to more intuitively understand the vehicle's charging and discharging status, so that when the vehicle is charged and discharged, it can be disconnected from the charging pile in time and put into use, thereby improving the vehicle's charging and discharging efficiency.

[0010] In one possible implementation, the second display scheme is applied to the target lights of the vehicle, including: when the first display scheme and the second display scheme do not conflict, the target lights are controlled simultaneously based on the first display scheme and the second display scheme; when the first display scheme and the second display scheme conflict, the target lights are first controlled to light up for a preset duration through the first display scheme, and then the target lights are lit through the second display scheme, or the target lights are controlled to light up in an alternating manner using the first display scheme and the second display scheme.

[0011] According to the above technical means, the vehicle will also automatically detect whether there is a conflict in lighting effect between the first display scheme and the second display scheme. If there is no conflict, the target light is controlled by the first display scheme and the second display scheme at the same time, so that the target light can express more information during the lighting process. If there is a conflict, the user is guided by staggering the first display scheme and the second display scheme to solve the problem of information confusion.

[0012] In a possible implementation manner, the first display scheme generated based on electricity price information and carbon emission data includes: obtaining a first matching relationship between electricity price values and the light flashing frequency; determining a first target frequency from the first matching relationship according to the electricity price information; generating a first display scheme based on the first target frequency; obtaining a second matching relationship between carbon emission amounts and light colors; determining a first target color from the second matching relationship according to the carbon emission amount; and updating the first display scheme based on the first target color.

[0013] In a possible implementation manner, the first display scheme generated based on electricity price information and carbon emission data includes: obtaining a third matching relationship between electricity price values and light colors; determining a second target color from the third matching relationship according to the electricity price information; generating a first display scheme based on the second target color; obtaining a fourth matching relationship between carbon emission amounts and the light flashing frequency; determining a second target frequency from the fourth matching relationship according to the carbon emission amount; and updating the first display scheme based on the second target frequency.

[0014] In a possible implementation manner, generating a second display scheme according to the charging state or the discharging state includes: if the charging state is a charging failure, taking the first preset sub-scheme as the second display scheme; if the charging state is the charging gun inserted but not charging, taking the second preset sub-scheme as the second display scheme; if the charging state is the charging gun inserted and charging, taking the third preset sub-scheme as the second display scheme; if the charging state is fully charged, taking the fourth preset sub-scheme as the second display scheme; if the charging state is scheduled charging, taking the fifth preset sub-scheme as the second display scheme; if the discharging state is a discharging failure, taking the sixth preset sub-scheme as the second display scheme; if the discharging state is the discharging gun inserted but not discharging, taking the seventh preset sub-scheme as the second display scheme; if the discharging state is the discharging gun discharging, taking the eighth preset sub-scheme as the second display scheme; if the discharging state is the discharging gun discharging to a preset warning value, taking the ninth preset sub-scheme as the second display scheme; if the discharging state is scheduled discharging, taking the tenth preset sub-scheme as the second display scheme; if the charging state and the discharging state are simultaneous charging and discharging, taking the eleventh preset sub-scheme as the second display scheme; where the first preset sub-scheme to the eleventh preset sub-scheme are all different, and the first preset sub-scheme to the eleventh preset sub-scheme at least include one control effect of flashing, pulsating, breathing, flowing water, and color.

[0015] According to the above technical means, the provided first display scheme and second display scheme are composed of various light effects such as flashing, pulsating, breathing, flowing water, and color, thereby significantly increasing the scenarios and quantities of information expressed by the light effects, so that users can more fully intuitively understand information on electricity price, carbon emission, and charging and discharging states through the vehicle's lights, and improving the expression accuracy of the target light information.

[0016] In a possible implementation, the steps of controlling the target lamp by the first display scheme and the second display method further include: monitoring the distance between the user and the vehicle; when the distance is short, using the ambient lamp in the vehicle as the target lamp and controlling the target lamp by the first display scheme and the second display method; when the distance is medium, using at least one of the daytime running lamp, position lamp, turn signal lamp, and rear tail lamp outside the vehicle as the target lamp and controlling the target lamp by the first display scheme and the second display method; when the distance is long, using at least one of the daytime running lamp, position lamp, turn signal lamp, and rear tail lamp outside the vehicle as the target lamp and controlling the target lamp by the first display scheme and the second display method; when the distance is long, simultaneously sending electricity price information and charge and discharge status information to the user terminal so that the user terminal can display the electricity price information and charge and discharge status information through the screen.

[0017] According to the above technical means, based on detecting the short, medium, and long distances between the user and the vehicle, different vehicle lights are switched as the target lamp, and in cooperation with the user terminal, the flexibility and convenience of the user to obtain electricity price information and charge and discharge status by observing the target lamp are significantly improved, and the speed and efficiency of the user to obtain information are improved.

[0018] In a possible implementation, monitoring the distance between the user and the vehicle includes: identifying the user near the vehicle through an ultra-wideband positioning radar, and when the user is detected, determining that the distance is short; when the ultra-wideband positioning radar fails to identify the user, detecting the signal strength of the wireless communication signal between the user device and the vehicle; when the signal strength is between the preset minimum strength threshold and the preset maximum strength threshold, determining that the distance is medium; when the signal strength is less than the preset minimum strength threshold, determining that the distance is long.

[0019] According to the above technical means, based on the mechanism of the ultra-wideband positioning radar and the wireless communication signal strength, the distance between the user and the vehicle is determined, thereby further improving the accuracy of user distance detection.

[0020] In a second aspect, the present invention provides a display device for grid electricity prices. The device includes: a request module for sending an electricity price request to the grid platform when the vehicle is connected to the charging device; an electricity price acquisition module for receiving the electricity price information sent by the grid platform in response to the electricity price request; a first display scheme generation module for generating a first display scheme based on the electricity price information, and the first display scheme is used to control the lighting effect of the target lamp on the vehicle, and the target lamp is a lamp installed inside or outside the vehicle; a target lamp display module for controlling the lighting of the target lamp on the vehicle based on the first display scheme.

[0021] In a third aspect, the present invention provides a vehicle, comprising: a memory and a processor, which are communicatively connected to each other. The memory stores computer instructions, and the processor executes the computer instructions to execute the method according to the first aspect or any corresponding embodiment thereof above.

[0022] In a fourth aspect, the present invention provides a computer-readable storage medium, on which computer instructions are stored. The computer instructions are used to cause a computer to execute the method according to the first aspect or any corresponding embodiment thereof above.

[0024] The technical solution provided by the present invention has the following advantages:

[0025] (1) According to the above technical means, when the vehicle establishes a charging connection with the charging device, it includes two situations: vehicle charging and discharging. The vehicle automatically sends a request to the power grid to obtain the electricity price, so that the electricity price information is transmitted into the vehicle. The vehicle controls the target lamp on the vehicle to be lit according to the specified lamp effect scheme in cooperation with the preset first display scheme according to the level of the electricity price, and directly uses the lamp effect of the vehicle to intuitively remind the user of the electricity price of the power grid. Furthermore, the user can select a suitable area or time for charging or discharging according to the level of the electricity price, which not only solves the problem of expensive charging or low discharging income for the user, but also can adjust the balance of power consumption of the power grid, promote more consumption of electricity when the power grid is idle, and reduce electricity consumption when the power grid is short of electricity, significantly improving the economy of the vehicle charging.

[0026] (2) According to the above technical means, in addition to obtaining the electricity price information, the vehicle also downloads carbon emission data from the power grid in real time after connecting to the charging pile to represent the high and low carbon emissions in different periods and different regions, and controls the target lamp on the vehicle to display the high and low carbon emissions with a preset lamp effect. By guiding the user to choose an environmentally friendly charging and discharging period for charging or discharging through the lighting effect, the environmental protection effect of the new energy vehicle can be further improved.

[0027] (3) According to the above technical means, when the vehicle is charging or discharging, different second display schemes can also be customized according to the corresponding charging and discharging states, such as plugging in the gun for charging, scheduled charging, plugging in the gun for discharging, the state of the charged electricity, etc., and applied to the target lamp of the vehicle. Thus, the target lamp of the vehicle can not only display information such as the electricity price, but also prompt the charging and discharging state of the vehicle, guiding the user to more intuitively understand the charging and discharging situation of the vehicle, so as to timely disconnect the connection with the charging pile and put it into use when the vehicle charging and discharging is completed, improving the charging and discharging efficiency of the vehicle.

[0028] (4) According to the above technical means, the vehicle will also automatically detect whether there is a conflict in lighting effects between the first display scheme and the second display scheme. If there is no conflict, the target light is controlled by the first display scheme and the second display scheme at the same time, so that the target light can express more information during the lighting process. If there is a conflict, the user is guided by staggering the first display scheme and the second display scheme to solve the problem of information confusion.

[0029] (5) According to the above technical means, the first display scheme and the second display scheme provided are composed of a combination of various lighting effects such as flashing, jumping, breathing, flowing water, and color, thereby significantly improving the scenarios and number of lighting effects that express information, so that users can more fully and intuitively understand the information on electricity prices, carbon emissions, and charging and discharging status through the vehicle's lights, thereby improving the accuracy of the expression of target light information.

[0030] (6) According to the above technical means, by detecting the close distance, medium distance and long distance between the user and the vehicle, switching different lights of the vehicle as target lights, and cooperating with the user terminal, the flexibility and convenience of the user in obtaining electricity price information and charging and discharging status by observing the target lights are significantly improved, and the speed and efficiency of the user in obtaining information are improved.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts fall within the protection scope of the present invention.

[0037] According to an embodiment of the present invention, an embodiment of a method for displaying grid electricity prices is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. And although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0038] In this embodiment, a method for displaying grid electricity prices is provided. Figure 1 It is a flowchart of a method for displaying grid electricity prices according to an embodiment of the present invention. As Figure 1 shown, the process includes the following steps:

[0039] Step S101: When the vehicle is connected to the charging device, send an electricity price request to the grid platform;

[0040] Step S102: Receive the electricity price information sent by the grid platform in response to the electricity price request;

[0041] Step S103: Generate a first display scheme based on the electricity price information. The first display scheme is used to control the lighting effect of the target lamp on the vehicle. The target lamp is a lamp installed inside or outside the vehicle;

[0042] Step S104: Control the target lamp on the vehicle to light up based on the first display scheme.

[0043] Specifically, the charge and discharge state display method provided in the embodiments of the present application can be applied to a terminal, or to a server, or can also be software running on a terminal or a server. In some embodiments, the terminal can be an electronic device such as a smartphone, a tablet computer, a laptop computer, or a desktop computer embedded in an electric vehicle. Of course, the terminal can also be an electric vehicle. If the electric vehicle is networked through a server, it can be configured as an independent physical server, or can be configured as a server cluster or a distributed system composed of multiple physical servers, or can also be configured as a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, and big data and artificial intelligence platforms; the software can be an application program for charge and discharge display, etc., but is not limited to the above forms.

[0044] In the embodiments of the present invention, a vehicle is taken as an example of the executing entity. The vehicle refers to a vehicle powered by electric energy, including but not limited to pure electric vehicles, range-extended electric vehicles, plug-in hybrid electric vehicles, fuel (hydrogen energy, ethanol) cell vehicles, etc. The charging device is a device used to charge the vehicle. Currently, the commonly used charging device is a charging pile set in the charging area. With the development of technology, the charging device can also be a wireless charging device. In this embodiment, the connection between the vehicle and the charging device includes but is not limited to wired connection and wireless connection. As long as the connection method can enable the charging device to supply power to the vehicle, it shall be within the protection scope of this application.

[0045] When the vehicle is connected to the charging device, it means that the vehicle is about to perform the work of charging or discharging. At this time, when the in-vehicle computer detects the connection signal between the vehicle and the charging device, it docks with the smart grid through the charging pile or the wireless communication module and sends a power price request to the grid platform. After receiving the power price request, the grid platform feeds back the latest power price information at the current time to the vehicle.

[0046] In the vehicle, a first display scheme is pre-configured. The first display scheme includes different lighting effects corresponding to different power prices. For example, different power prices correspond to different colors, or different power prices correspond to different lighting brightness, or different power prices correspond to different lighting flashing frequencies. This embodiment only takes this as an example and is not limited thereto. Thus, the vehicle generates a first display scheme according to the power price information. The first display scheme is used to control the lighting effect of the target lamp on the vehicle, so that the target lamp on the vehicle is displayed according to the first display scheme. In this embodiment, the target lamp refers to a lamp installed inside or outside the vehicle, including but not limited to the ambient lamp inside the vehicle, the turn signal outside the vehicle, the daytime running lamp, the running light, the prompt lamp near the charging port, etc.

[0047] In addition, in this embodiment, in addition to the target lamp, the power price information obtained by the vehicle can also be directly displayed on the in-vehicle screen of the vehicle.

[0048] According to the above technical means, when the vehicle establishes a charging connection with the charging device, the vehicle automatically sends a request to the power grid to obtain the electricity price, so that the electricity price information is transmitted to the vehicle. The vehicle controls the target lights on the vehicle to be lit according to the specified lighting effect scheme in cooperation with the preset first display scheme according to the level of the electricity price, so as to directly remind the user of the power grid electricity price intuitively through the lighting effect of the vehicle. Furthermore, it guides the user to choose a suitable area or time for charging or discharging according to the level of the electricity price. For example, when the lighting effect of the target light indicates that the current electricity price is high, the charging user can cancel the charging and choose another time or area with a low electricity price for charging to avoid excessive consumption; while the discharging user can safely choose the current area for discharging because more discharging income can be obtained. It not only solves the problem of expensive charging or less discharging income for users, but also can adjust the balance of power grid power consumption. For example, it promotes more consumption of the power grid power when the grid is idle and reduces power consumption when the grid is short of power. Through the above scheme, not only the economy of the vehicle charging is significantly improved, but also the user does not need to use devices such as mobile phones and computers to query the electricity price of the local area at that time period, saving the user's operation and solving the problem that some users who cannot use terminals such as mobile phones cannot obtain the electricity price. In addition, compared with some charging pile schemes equipped with electricity price prompts, since the charging pile manufacturers are different, even if the charging pile does not have the function of electricity price prompt, the embodiments of the present invention can also use the vehicle's own lights to prompt the user, significantly increasing the convenience for the user to obtain the electricity price.

[0049] In some alternative embodiments, the charge and discharge state display method provided by the present invention further includes:

[0050] Step a1, sending a carbon emission request to the power grid platform;

[0051] Step a2, receiving the carbon emission data sent by the power grid platform in response to the carbon emission request;

[0052] Step a3, updating the first display scheme based on the carbon emissions represented by the carbon emission data.

[0053] Specifically, the embodiments of the present invention also provide a lighting effect guiding function for carbon emissions. When the vehicle establishes a connection with the charging device, the vehicle also sends a carbon emission request for obtaining carbon emission data to the power grid platform, so that the power grid platform feeds back the carbon emission data to the vehicle in response to the carbon emission request. The carbon emission data is data recording the carbon emissions in each region at the current time and can characterize the environmental protection situation in different regions at the current time.

[0054] The vehicle updates the first display scheme based on the carbon emission data. For example, in an alternative embodiment, green lights are used for low carbon emissions and red lights are used for high carbon emissions. Combining with the first display scheme of the electricity price information, in an alternative embodiment, the first display scheme can be a combination of color representing carbon emissions + blinking frequency representing the level of the electricity price.

[0055] According to the above technical means, in addition to obtaining electricity price information, the vehicle also downloads carbon emission data from the power grid in real time after connecting to the charging pile to represent the high and low carbon emissions in different regions at different times, and controls the target lights on the vehicle to display the high and low carbon emissions with a preset light effect. By guiding users to choose environmentally friendly charging and discharging periods through the light effect, the environmental protection effect of using electricity for new energy vehicles can be further improved.

[0056] In some alternative embodiments, the charge and discharge state display method provided by the present invention further includes:

[0057] Step b1, obtaining the operating state of the vehicle;

[0058] Step b2, when the operating state is a stationary state, determining whether the vehicle is in a charging state or a discharging state;

[0059] Step b3, generating a second display scheme according to the charging state or the discharging state;

[0060] Step b4, applying the second display scheme to the target lights of the vehicle.

[0061] Specifically, in addition to displaying electricity prices and carbon emissions through lights, the vehicle provided by the present invention can also display the charge and discharge states. Before the display, first monitor the operating state of the electric vehicle, and the operating state includes a driving state and a stationary state. If it is detected that the electric vehicle is in a stationary state (the stationary state means that the electric vehicle gear is in the P gear mode and the vehicle machine display screen is in the off state), at this time the vehicle may establish an electrical connection with the charging device, so as to obtain the charge and discharge state of the electric vehicle. In this embodiment, the charge and discharge state includes a charging state and a discharging state. Due to the different charge and discharge states, different states can represent different charge and discharge progress. Intuitively displaying the charge and discharge state to the user through the light effect of the target lights can improve the efficiency of the user's understanding of the charge and discharge progress.

[0062] In the embodiment of the present invention, the vehicle controls the target lights to respond with a second display scheme according to the situations corresponding to the charging state or / and the discharging state. Among them, the second display scheme can be composed of a combination of colors and lighting methods, and the display content of the second display scheme corresponds to each situation of the charge and discharge state.

[0063] In this embodiment, judging the situations corresponding to the electric vehicle in the charging state or / and the discharging state through the charge and discharge signal may include charging failure, normal charging, reserved charging, discharging failure, simultaneous charging and discharging, etc.

[0064] By combining the color, flashing, breathing, flowing, jumping, frequency, etc. of the target light, different situations corresponding to the charging and discharging status can be characterized. For example, the magnitude of the frequency can be positively correlated with the magnitude of the charging power or the discharging power. In an embodiment of the present invention, according to the situation corresponding to the charging state and / or discharging state of the vehicle, a combination of color and light effects is used to intuitively display the charging and discharging status, and the user-defined function increases flexibility, and controls the target light to respond to a preset display scheme. By customizing different second display schemes and applying them to the target lights of the vehicle, the target lights of the vehicle can not only display information such as electricity prices, but also prompt the charging and discharging status of the vehicle, guiding users to more intuitively understand the charging and discharging of the vehicle, so that when the charging and discharging of the vehicle is completed, the connection with the charging pile can be promptly disconnected and put into use, thereby improving the charging and discharging efficiency of the vehicle.

[0065] In some optional implementations, the above step b4 includes:

[0066] Step c1, when the first display scheme and the second display scheme do not conflict, controlling the target light based on the first display scheme and the second display scheme simultaneously;

[0067] Step c2, when the first display scheme and the second display scheme conflict, first control the target light to light up for a preset time using the first display scheme, and then light up the target light using the second display scheme, or control the target light to light up in an alternating manner using the first display scheme and the second display scheme.

[0068] Specifically, in the embodiment of the present invention, the first display scheme and the second display scheme are both control schemes based on a combination of light effects such as flashing, color, and flowing water, and are customized and generated according to the user's wishes. On this basis, if the first display scheme and the second display scheme are display control schemes that do not conflict at all, the target light is controlled by the first display scheme and the second display scheme at the same time, so that the target light can express more information during the lighting process, thereby improving the user's ability to perceive the charging status.

[0069] If the first display scheme and the second display scheme have conflicts in some lighting effects, for example, the first display scheme involves color, and the second display scheme also involves color, and the two colors cannot be displayed at the same time. Then the embodiment of the present invention first controls the target light to be lit for a preset duration through the first display scheme, and then controls the target light to be lit through the second display scheme. For example, after the first display scheme lights up the target light for a preset duration, it turns off or displays it in other ways that are always on to indicate a scheme switching moment, and then lights up the target light with the second display scheme. Alternatively, the target light is controlled to be lit in an alternating manner with the first display scheme and the second display scheme. Thus, by guiding the user in a staggered display manner of the first display scheme and the second display scheme, the problem of confusing guidance information is solved, and the accuracy of the user's perception of the charging and discharging status of the vehicle is improved.

[0070] In some alternative embodiments, the specific steps of the first display scheme generated based on electricity price information and carbon emission data include:

[0071] Step d1, obtain the first matching relationship between the electricity price value and the light flashing frequency;

[0072] Step d2, determine the first target frequency from the first matching relationship according to the electricity price information;

[0073] Step d3, generate the first display scheme based on the first target frequency;

[0074] Step d4, obtain the second matching relationship between the carbon emission and the light color;

[0075] Step d5, determine the first target color from the second matching relationship according to the carbon emission;

[0076] Step d6, update the first display scheme based on the first target color.

[0077] Specifically, the present invention provides a specific application embodiment of the first display scheme. It includes a first display scheme that represents the electricity price value by the light flashing frequency and characterizes the carbon emission by the color. Among them, a first matching relationship between the electricity price value and the light flashing frequency is pre-configured. For example, the first matching relationship can be that the light flashing frequency increases as the electricity price value increases, or the light flashing frequency decreases as the electricity price value increases. As long as the first matching relationship can correspond the electricity price value and the light flashing frequency one by one. When the vehicle obtains the electricity price information, it queries the first target frequency corresponding to the electricity price information from the first matching relationship, so as to control the target light of the vehicle to flash at the first target frequency, giving the user a guiding effect on the electricity price.

[0078] Correspondingly, a second matching relationship between the carbon emission and the light color is also pre-configured. For example, when the carbon emission is the lowest, it is green, and when the carbon emission is the highest, it is red. As the carbon emission increases, the color in the second matching relationship is recorded as a gradient color that changes from green to red. When the vehicle obtains the carbon emission, it queries the first target color corresponding to the carbon emission from the second matching relationship, so as to control the target light of the vehicle to emit light at the first target color, giving the user a guiding effect on the carbon emission.

[0079] Through the above technical means, the changes in the light flashing and the light color can be displayed at the same time, so as to achieve the comprehensive guiding effect of carbon emission and electricity price based on the cooperation of flashing and color, improving the accuracy and efficiency of the user to obtain grid information.

[0080] In some alternative embodiments, the specific steps of the first display scheme generated based on electricity price information and carbon emission data include:

[0081] Step e1, obtain the third matching relationship between the electricity price value and the light color;

[0082] Step e2, determine the second target color from the third matching relationship according to the electricity price information;

[0083] Step e3, generate the first display scheme based on the second target color;

[0084] Step e4, obtain the fourth matching relationship between the carbon emission and the light flashing frequency;

[0085] Step e5, determine the second target frequency from the fourth matching relationship according to the carbon emission;

[0086] Step e6, update the first display scheme based on the second target frequency.

[0087] Specifically, steps e1 to e6 are specific scenario embodiments for characterizing the carbon emission through the light flashing frequency and characterizing the electricity price through the color. The principles of steps e1 to e6 are the same as those of the foregoing steps d1 to d6, and reference can be made to the descriptions of the foregoing steps d1 to d6, which will not be elaborated here.

[0088] In some alternative embodiments, the above step b3 includes:

[0089] Step f1, if the charging status is a charging failure, use the first preset sub-scheme as the second display scheme;

[0090] Step f2, if the charging status is that the charging gun is plugged in but not charging, use the second preset sub-scheme as the second display scheme;

[0091] Step f3, if the charging status is that the charging gun is plugged in and charging, use the third preset sub-scheme as the second display scheme;

[0092] Step f4, if the charging status is fully charged, use the fourth preset sub-scheme as the second display scheme;

[0093] Step f5, if the charging status is scheduled charging, use the fifth preset sub-scheme as the second display scheme;

[0094] Step f6, if the discharging status is a discharging failure, use the sixth preset sub-scheme as the second display scheme;

[0095] Step f7, if the discharging status is that the discharging gun is plugged in but not discharging, use the seventh preset sub-scheme as the second display scheme;

[0096] Step f8, if the discharging status is that the discharging gun is plugged in and discharging, use the eighth preset sub-scheme as the second display scheme.

[0097] Step f9, if the discharge state is charging with the charging gun plugged in until a preset warning value is reached, then use the ninth preset sub-scheme as the second display scheme;

[0098] Step f10, if the discharge state is scheduled discharge, then use the tenth preset sub-scheme as the second display scheme;

[0099] Step f11, if the charging state and the discharge state are simultaneous charging and discharging, then use the eleventh preset sub-scheme as the second display scheme;

[0100] Among them, the first preset sub-scheme to the eleventh preset sub-scheme are all different, and the first preset sub-scheme to the eleventh preset sub-scheme at least include one control effect among flashing, pulsating, breathing, flowing water, and color.

[0101] Specifically, in the embodiments of the present invention, the charging and discharging states of the vehicle include eleven different state representations, specifically including charging failure, charging gun not charging, charging gun plugged in and charging, fully charged, scheduled charging, discharging failure, charging gun not discharging, charging gun discharging, charging gun discharging, scheduled discharging, and simultaneous charging and discharging. Based on the above eleven different charging and discharging states, the embodiments of the present invention respectively define eleven different preset sub-schemes to represent the second display scheme. Each preset sub-scheme is generated by one of flashing, pulsating, breathing, flowing water, and color. Thus, for each charging and discharging state, the second display scheme can accurately display, so as to guide the user to fully understand the charging and discharging progress, significantly improve the scenarios and quantities of the information expressed by the lamp effect, so that the user can more fully intuitively understand the electricity price, carbon emissions, and charging and discharging state information through the vehicle's lights, and improve the expression accuracy of the target lamp information.

[0102] For example, in an embodiment of a specific scenario, the above first preset sub-scheme to the eleventh preset sub-scheme may include:

[0103] If the charging state is charging failure, then use red flashing as the second display scheme;

[0104] If the charging state is charging gun not charging, then use blue constant on as the second display scheme;

[0105] If the charging state is charging gun plugged in and charging, then use green flashing as the second display scheme;

[0106] If the charging state is fully charged, then use green constant on as the second display scheme;

[0107] If the charging state is scheduled charging, then use blue and purple alternating flashing as the second display scheme;

[0108] If the discharge state is discharging failure, then use yellow constant on as the second display scheme;

[0109] If the discharge state is that the charging gun is inserted but not discharging, then use a constantly lit gray color as the second display scheme;

[0110] If the discharge state is that the charging gun is inserted and discharging, then use a flashing gray color as the second display scheme;

[0111] If the discharge state is that the charging gun discharges to a preset warning value, then use a flashing orange color as the second display scheme;

[0112] If the discharge state is scheduled discharge, then use a light yellow flowing water as the second display scheme;

[0113] If the charging state and the discharge state are simultaneous charging and discharging, then use an alternating flashing of blue and green as the second display scheme.

[0114] In some alternative embodiments, the embodiments of the present invention can also distinguish the charging stages (constant current / constant voltage / trickle) and discharge modes (V2L / V2G / V2V), and represent different charging and discharging stages by establishing a dynamic light effect library, and the dynamic light effect library supports user-defined parameters. In some alternative embodiments, it is also allowed to set color values corresponding to different battery state of charge levels (low / medium / high). For example, when the battery state of charge is higher, the corresponding color value is deeper, and when the battery state of charge is lower, the corresponding color value is shallower.

[0115] In some alternative embodiments, the steps of controlling the target lamp by the first display scheme and the second display method in the embodiments of the present invention further include:

[0116] Step g1, monitor the distance between the user and the vehicle;

[0117] Step g2, when the distance is short, use the ambient lamp in the vehicle as the target lamp, and control the target lamp by the first display scheme and the second display method;

[0118] Step g3, when the distance is medium, use at least one of the daytime running lamp, position lamp, turn signal lamp, and rear tail lamp outside the vehicle as the target lamp, and control the target lamp by the first display scheme and the second display method;

[0119] Step g4, when the distance is long, use at least one of the daytime running lamp, position lamp, turn signal lamp, and rear tail lamp outside the vehicle as the target lamp, and control the target lamp by the first display scheme and the second display method; when the distance is long, simultaneously send electricity price information and charge and discharge state information to the user terminal so that the user terminal displays the electricity price information and charge and discharge state information through the screen.

[0120] Specifically, the embodiment of the present invention provides a vehicle target light control scheme for different distances. In this embodiment, the target lights of the vehicle include, but are not limited to, ambient lights, daytime running lights, position lights, turn signals, and taillights. In this embodiment, based on the positioning technology, the distance between the user and the vehicle is determined, and the distance between the user and the vehicle is determined to be one of close range, medium range, or long range through different distance thresholds. When the user is in close proximity to the vehicle (for example, the user is sitting in the vehicle or standing outside the vehicle door), the embodiment of the present invention uses the ambient lights inside the vehicle as the target lights and controls the target lights through the first display scheme and the second display method. When the user is at a medium distance from the vehicle (for example, the user and the vehicle are within the range of 3 - 10 meters), this embodiment uses at least one of the daytime running lights, position lights, turn signals, and taillights outside the vehicle as the target lights, so that it is easier to display the electricity price information and the charge and discharge status to the user through the lights outside the vehicle. When the user is at a long distance from the vehicle, for example, at a distance greater than 10 meters, on the one hand, at least one of the daytime running lights, position lights, turn signals, and taillights outside the vehicle is used as the target lights to display to the user, and on the other hand, the vehicle transmits the electricity price information and the charge and discharge status information to the user terminal (such as the user's mobile phone, tablet, etc.) through a wireless communication mechanism, so that the user terminal displays the electricity price information and the charge and discharge status information through the screen. Thus, when the user is far from the vehicle, the user can also obtain the display of the electricity price information in real time and understand the charge and discharge progress of the vehicle. According to the above technical means, based on detecting the close, medium, and long distances between the user and the vehicle, different lights of the vehicle are switched as the target lights and cooperate with the user terminal, significantly improving the flexibility and convenience for the user to obtain the electricity price information and the charge and discharge status by observing the target lights, and improving the speed and efficiency of the user to obtain information.

[0121] In some alternative embodiments, the above step g1 includes:

[0122] Step g11, identifying the user near the vehicle through an ultra-wideband positioning radar, and when the user is detected, determining the distance as close range;

[0123] Step g12, when the ultra-wideband positioning radar fails to identify the user, detecting the signal strength of the wireless communication signal between the user device and the vehicle;

[0124] Step g13, when the signal strength is between the preset minimum strength threshold and the preset maximum strength threshold, determining the distance as medium range;

[0125] Step g14, when the signal strength is less than the preset minimum strength threshold, determining the distance as long range.

[0126] Specifically, the embodiments of the present invention provide a detection solution for the close, medium, and long distances between users and vehicles. Among them, when the vehicle is charging or discharging, the ultra-wideband positioning radar is activated. Ultra-wideband (UWB) technology is a wireless carrier communication technology that can achieve centimeter-level positioning accuracy for target objects, so that high-precision positioning effects can be achieved for users inside and near the vehicle. As long as the user falls within the positioning range of the ultra-wideband positioning radar, it can be regarded as the close distance state between the user and the vehicle. In some optional embodiments, an in-vehicle camera can also be used to assist the ultra-wideband positioning radar in jointly positioning the close-distance users to increase the user positioning accuracy. When the ultra-wideband positioning radar fails to identify the user, it is necessary to determine whether the distance between the user and the vehicle is long or medium. In this embodiment, medium-distance positioning is achieved based on the principle that the signal of the wireless communication device attenuates with distance. In this embodiment, the wireless communication device can be a Bluetooth device or a WIFI device used and carried by the user, and the corresponding wireless communication signals include but are not limited to Bluetooth signals and WIFI signals.

[0127] At the same time, the embodiments of the present invention pre-define a preset minimum intensity threshold and a preset maximum intensity threshold for the signal intensity of the wireless communication signal, which are used to represent the minimum range and the maximum range of the medium distance respectively. Thus, when the wireless communication signal intensity falls within the range of the preset minimum intensity threshold and the preset maximum intensity threshold, it can be determined that the distance between the user and the vehicle is medium; while when the wireless communication signal intensity exceeds the preset maximum intensity threshold, it can be determined that the user and the vehicle are in the long-distance state. According to the above technical means, the distance between the user and the vehicle is determined based on the mechanism of the ultra-wideband positioning radar and the wireless communication signal intensity, thereby further improving the accuracy of user distance detection.

[0128] In addition, in some optional embodiments, the booth direction of the user can be further determined according to the ultra-wideband positioning radar and the wireless communication signal intensity. Thus, when the user is outside the vehicle, based on the booth direction of the user, the vehicle can select a lamp that is consistent with the user's direction from the external lamps of the vehicle such as the daytime running lights, position lights, turn signals, and rear tail lights as the target lamp, thereby further improving the convenience of the user observing the target lamp. At the same time, as the user moves, the target lamp dynamically switches among the external lamps of the vehicle such as the daytime running lights, position lights, turn signals, and rear tail lights along with the user's direction, further improving the convenience of the user observing the target lamp.

[0129] The technical solution provided by the present invention improves the interaction experience between the vehicle and the user. Through spatial light effects guidance, it realizes "what you see is what you get" interaction of electricity price, carbon emissions, charging and discharging, which is associated with five dimensions of SOC / power / temperature / electricity price / carbon emissions, and improves the user recognition efficiency. It supports personalized light effect configuration. Users can define exclusive solutions through the mobile APP, customize in-depth parameters, and save them in a scenario-based manner. It realizes system cost optimization, reuses existing vehicle lamp components, reduces the number of independent indicator modules, and reduces the hardware cost. It adopts a software-defined light effect mode, eliminating the need for physical structure modification. It enables intelligent energy management, combines grid price signals with the vehicle's SOC status, provides a visual expression of charging and discharging strategy suggestions, and supports visual tracking of the energy flow direction in the V2X mode.
