Description

Technical Field

[0001] This invention relates to the field of electric vehicle technology, and more specifically, to a protection system and method for vehicle-to-vehicle charging. Background Technology

[0002] In the field of new energy vehicles, vehicle-to-vehicle charging technology, which involves the vehicle's ability to discharge electricity, is already a relatively mature technology. However, there are still some problems to be solved in the area of ​​vehicle-to-vehicle charging.

[0003] Specifically, in the practical application of vehicle-to-vehicle charging, it is necessary to warn oncoming vehicles in various scenarios, including but not limited to the following three scenarios: Scenario 1: Two lanes merging into a single lane at an intersection during vehicle-to-vehicle charging; Scenario 2: Other vehicles suddenly cutting in at close range during vehicle-to-vehicle charging; Scenario 3: Vehicles accelerating to overtake during vehicle-to-vehicle charging. This allows surrounding drivers to clearly and quickly identify which two vehicles are currently charging each other, thus avoiding potential problems that could interfere with vehicle-to-vehicle charging in the aforementioned scenarios. Related technologies use hazard lights and indicator lights at the rear of the vehicle for warning, but the warning effect of indicator lights at the rear is limited, only making it noticeable to vehicles approaching from behind. Therefore, using hazard lights and indicator lights at the rear of the vehicle cannot effectively solve the warning problem of vehicle-to-vehicle charging.

[0004] There is currently no effective solution to the problem that in related technologies, vehicle-to-vehicle charging uses indicator lights and hazard lights at the rear of the vehicle to warn other vehicles, which only makes the vehicles behind notice the signal.

[0005] Therefore, it is necessary to improve the relevant technology to overcome the aforementioned defects. Summary of the Invention

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0036] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0037] To address the aforementioned issues, this embodiment provides a protection system for vehicle-to-everything (V2X) charging while driving. (See attached document.) Figure 1 and Figure 2 The system includes:

[0038] A first vehicle 1 and a second vehicle 2 are respectively provided with a first holographic display device 11 and a second holographic display device 21 at their top ends.

[0039] The first holographic display device 11 is used to display a first holographic image to indicate that the first vehicle 1 is in a vehicle-to-vehicle charging state, and the second holographic display device 21 is used to display a second holographic image to indicate that the second vehicle 2 is in a vehicle-to-vehicle charging state. A charging cable 4 is connected between the first vehicle 1 and the second vehicle 2. The structure of the charging cable 4 and its connection with the first vehicle 1 and the second vehicle 2 can adopt any structure in the prior art, and there is no limitation herein.

[0040] In the aforementioned system, a first holographic display device 11 and a second holographic display device 21 are respectively installed on the top of the first vehicle 1 and the top of the second vehicle 2. The first holographic display device 11 displays a first holographic image to indicate that the first vehicle 1 is in a vehicle-to-vehicle charging state, and the second holographic display device 21 displays a second holographic image to indicate that the second vehicle 2 is in a vehicle-to-vehicle charging state. A charging cable 4 connects the first vehicle 1 and the second vehicle. That is, by displaying holographic images on the tops of the two vehicles engaged in vehicle-to-vehicle charging, the system solves the problem that warnings of vehicle-to-vehicle charging via indicator lights and hazard lights at the rear of the vehicle are only noticeable to vehicles approaching from behind. Therefore, by using rooftop holographic warnings, the coverage of the warning information is expanded, ensuring that vehicles from all directions can clearly see that the first and second vehicles are engaged in vehicle-to-vehicle charging.

[0041] In an exemplary embodiment, the protection system includes a flexible connection device 3, with its two ends connected to the first vehicle 1 and the second vehicle 2, respectively. The flexible connection device 3 is used to indicate that the first vehicle 1 and the second vehicle 2 are in a vehicle-to-vehicle charging state and to prevent other vehicles from cutting in. This embodiment, by combining a holographic display device with the flexible connection device 3, can better warn vehicles approaching from all directions during vehicle-to-vehicle charging. Specifically, the holographic display device and the flexible connection device work together. The holographic display device is placed on the roof of the vehicle, avoiding the safety issues caused by insufficient light at night making the flexible connection device between vehicles difficult to observe. The flexible connection device 3 can more directly deter and warn against cutting in and overtaking, ensuring that vehicles traveling on both sides will not interfere with vehicle-to-vehicle charging when the warning effect of the holographic display device is weaker during the day compared to night. Furthermore, the flexible connection device 3 is flexible in length, allowing it to extend or retract as the relative distance between the two vehicles changes.

[0042] In an exemplary embodiment, the charging cable 4 is connected between the front of the first vehicle 1 and the rear of the second vehicle 2; it includes two sets of elastic connecting devices 3 spaced apart along a first direction, both connected between the front of the first vehicle 1 and the rear of the second vehicle 2, and the charging cable 4 is located between the two sets of elastic connecting devices 3 along the first direction, wherein the first direction is perpendicular to the travel direction of the first vehicle and the second vehicle. See also Figure 3In the vehicle-to-vehicle charging system, the first vehicle 1 and the second vehicle 2 are connected by two sets of parallel elastic connection devices 3. The charging cable 4 is placed between the two sets of elastic connection devices 3, providing better protection for the charging process between the two vehicles. However, besides the parallel connection method, alternative solutions include cross-connection, multiple sets of elastic connection devices, and elastic connection devices with lighting. The elastic connection devices 3 can use prominent colors such as fluorescent yellow for better warning. The elastic connection devices can also employ springs or other elastic components.

[0043] In one exemplary embodiment, such as Figure 3 As shown, the first holographic display device 11 includes a first display screen 111 and N first projection plates 112 respectively connected to the first display screen 111, wherein N is a positive integer; the first display screen 111 is used to project a first holographic image; the N first projection plates 112 are used to refract the first holographic image projected by the first display screen 111 to display the first holographic image; as shown Figure 4 As shown, the second holographic display device 21 includes a second display screen 211 and M second projection plates 212 respectively connected to the second display screen 211, wherein M is a positive integer; the second display screen 211 is used to project a second holographic image; the M second projection plates 212 are used to refract the second holographic image projected by the second display screen 211 to display the second holographic image.

[0044] Optionally, the projection direction of the display screens of the holographic display device, including the first holographic display device 11 and the second holographic display device 21, can be downward projection. (See below) Figure 3 Alternatively, the display screen can be projected upwards. (See below) Figure 6 The projection direction does not affect the final imaging effect, but to protect the holographic display device in rainy or snowy weather and avoid potential damage to the device, a downward projection method is preferred.

[0045] In an exemplary embodiment, the top of the first vehicle 1 is provided with a first groove 12. One end of each of the N first projection panels 112 is rotatably connected to the first display screen 111, and the other end of each of the N first projection panels 112 is slidably disposed in the first groove 12. When the other end of the N first projection panels 112 slides away from the first display screen 111, the first display screen 111 can move towards the first groove 12, so that the first holographic display device 11 is laid flat in the first groove 12. When the other end of the N first projection panels 112 slides towards the first display screen 111, the first display screen 111 can move away from the first groove 12, so that the N first projection panels 112 and the first display screen 111 combine to form a three-dimensional structure, such as a multi-faceted platform or other three-dimensional structure, constituting the first holographic display device 11. The second vehicle 2 has a second groove 22 on its top. One end of each of the M second projection plates 212 is rotatably connected to the second display screen 211, and the other end of each of the M second projection plates 212 is slidably disposed in the second groove 22. When the other end of the M second projection plates 212 slides away from the second display screen 211, the second display screen 211 can move towards the second groove 22, so that the second holographic display device 12 is laid flat in the second groove 22. When the other end of the M second projection plates 212 slides towards the second display screen 211, the second display screen 211 can move away from the second groove 22, so that the M second projection plates 212 and the second display screen 211 are combined to form a three-dimensional structure, such as a multi-faceted platform, to constitute the second holographic display device. The rotatable connection between the display screen and the projection panel can adopt existing structures, such as setting a sleeve on the projection panel and setting a rotating shaft on the display screen, and achieving the rotatable connection by fitting the sleeve onto the rotating shaft; while the sliding connection between the projection panel and the groove can also be achieved by using existing slide rails and sliders, etc., which will not be described in detail here.

[0046] Specifically, taking the first holographic display device 11 of the first vehicle 1 as an example, see... Figure 3 and Figure 5The first holographic display device 11 includes a first display screen 111 and four first projection panels 112 respectively connected to the first display screen 111, i.e., N=4. Further, the first holographic display device 11 employs a four-sided pseudo-holographic projection. The four-sided pseudo-holographic projection is a 45° inclined four-sided platform made of holographic glass, holographic film, or a combination of holographic glass and holographic film. It can utilize video sources of two-dimensional objects captured from four different angles, then refract the images at a 45-degree angle and converge them to form a three-dimensional image with sensory dimensions. Optionally, transparent panels such as acrylic can be used instead of holographic glass to make the four-sided pseudo-holographic projection. Furthermore, when not in use for vehicle-to-vehicle charging, and the first holographic display device 11 is in the off state, it lies flat within the first groove 12 and is embedded in the vehicle roof. When the first holographic display device 11 is turned on, each of the first projection panels 112 slides towards the first display screen 111, causing the first display screen 111 to move away from the first groove 12. The first display screen 111 and the first projection panels 112 combine to form a four-sided platform for displaying the first holographic image. When charging is finished and the holographic projection is turned off, each of the first projection panels 112 in the first holographic display device 11 slides back to the flat state. The second holographic display device 21 can adopt the same structure as the first holographic display device 11, and will not be described further here.

[0047] The holographic display device used in this embodiment of the invention is low in cost and has a good projection effect. It can be automatically assembled and disassembled. When not charging while driving, the holographic projection device is laid flat and embedded in the roof of the vehicle, thereby reducing the waste of space. When projection begins, it automatically assembles into a three-dimensional structure. When an obstacle located above the roof is encountered, the holographic projection device can return to the flat state to avoid damage to the holographic projection device.

[0048] The methods and embodiments provided in this invention can be executed on a computer terminal or similar computing device. Taking running on a computer terminal as an example, Figure 7 This is a hardware structure block diagram of the computer terminal for the vehicle-to-vehicle charging protection method according to an embodiment of the present invention. Figure 7 As shown, a computer terminal may include one or more Figure 7 The diagram shows only one processor 702, which may include, but is not limited to, a microprocessor unit (MPU) or a programmable logic device (PLD), and a memory 704 for storing data. In an exemplary embodiment, the computer terminal may also include a transmission device 706 for communication functions and an input / output device 708. Those skilled in the art will understand that... Figure 7The structure shown is for illustrative purposes only and does not limit the structure of the computer terminal described above. For example, the computer terminal may also include components that are more complex than those described above. Figure 7 The more or fewer components shown, or having the same Figure 7 Equivalent functions or ratios shown Figure 7 The functions shown have more different configurations.

[0049] The memory 704 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the vehicle charging protection method in this embodiment of the invention. The processor 702 executes various functional applications and data processing by running the computer program stored in the memory 704, thereby implementing the above-described method. The memory 704 may include high-speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 704 may further include memory remotely located relative to the processor 702, and these remote memories can be connected to a computer terminal via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0050] Transmission device 706 is used to receive or send data via a network. Specific examples of the network described above may include a wireless network provided by a communication provider for the computer terminal. In one example, transmission device 706 includes a Network Interface Controller (NIC), which can connect to other network devices via a base station to communicate with the Internet. In another example, transmission device 706 may be a Radio Frequency (RF) module, used for wireless communication with the Internet.

[0051] To address the aforementioned issues, this embodiment provides a protection method for vehicle-to-vehicle charging interoperability, applied to the aforementioned computer terminal. Figure 8 This is a flowchart of a vehicle-to-vehicle charging protection method according to an embodiment of the present invention, the process including the following steps:

[0052] Step S802: When the first vehicle 1 and the second vehicle 2 are successfully connected by the charging cable and the first vehicle 1 and the second vehicle 2 are in a mutual charging state, turn on the first holographic display device 11 and the second holographic display device 21, wherein the first holographic display device 11 is disposed on the top of the first vehicle 1 and the second holographic display device 21 is disposed on the top of the second vehicle 2.

[0053] Step S804: Control the first holographic display device 11 to display the first holographic image and the second holographic display device 21 to display the second holographic image, wherein the first holographic image is used to indicate that the first vehicle 1 is in a vehicle mutual charging state, and the second holographic image is used to indicate that the second vehicle 2 is in a vehicle mutual charging state.

[0054] Optionally, the first holographic display device 11 and the second holographic display device 21 can display the same holographic image.

[0055] Through the above steps, after successfully connecting the first vehicle 1 and the second vehicle 2 via charging cables, and with the first vehicle 1 and the second vehicle 2 in a mutual charging state, the first holographic display device 11 and the second holographic display device 21 are activated. The first holographic display device 11 is located on the top of the first vehicle 1, and the second holographic display device 21 is located on the top of the second vehicle 2. The first holographic display device 11 displays a first holographic image, and the second holographic display device 21 displays a second holographic image. The first holographic image indicates that the first vehicle 1 is in a mutual charging state, and the second holographic image indicates that the second vehicle 2 is in a mutual charging state. That is, by displaying holographic images on the roofs of the two vehicles engaged in mutual charging, the problem of using indicator lights and hazard lights at the rear of the vehicle for warnings is solved, as these warnings are only noticed by vehicles approaching from behind. Therefore, by using rooftop holographic warnings, the coverage of the warning information is expanded, ensuring that vehicles from all directions can clearly see that the first and second vehicles are mutually charging.

[0056] In an exemplary embodiment, the method further includes: determining whether the first vehicle 1 and the second vehicle 2 are connected by an elastic connection device 3, wherein the elastic connection device 3 is used to indicate that the first vehicle 1 and the second vehicle 2 are in a vehicle mutual charging state and to prevent other vehicles from cutting in; determining the current connection mode of the elastic connection device; and if the current connection mode is determined to be the same as the preset connection mode, the elastic connection device is successfully connected.

[0057] It is understood that in this embodiment of the invention, the flexible connection device and the holographic display device can be used independently for a warning purpose. That is, confirming whether the flexible connection device is successfully connected is unrelated to whether the first and second holographic display devices are turned on; there is no sequential relationship between their activation and deactivation. Confirmation can be made first regarding the successful connection of the flexible connection device, or first regarding the activation of the first and second holographic display devices, or both can be performed simultaneously. For example, if it is determined that the current connection method of the flexible connection device is the same as the preset connection method, then activation of both the first and second holographic display devices is permitted.

[0058] Furthermore, this embodiment of the invention simultaneously uses Scheme 1: holographic display technology, and Scheme 2: connecting the first vehicle 1 and the second vehicle 2 through the elastic connection device 3. The combination of these two schemes is used to provide driving warnings to surrounding vehicles of the first vehicle 1 and the second vehicle 2 that are connected by vehicle-to-vehicle communication.

[0059] Specifically, Option 1 can use four-sided pseudo-holographic projection technology; Option 2 can use a spring structure installed between vehicles. Both options can block and warn vehicles coming from all directions.

[0060] Furthermore, regarding the above-mentioned Scheme 1: a first holographic display device 11 and a second holographic display device 21 are respectively installed on the roofs of the first vehicle 1 and the second vehicle 2, such as... Figure 2 As shown. The first holographic display device 11 and the second holographic display device 21 can adopt the structure described in the above embodiments, for example, both adopt four-sided pseudo-holographic projection, such as... Figures 3 to 5 As shown, this four-sided pseudo-holographic projection uses a 45° tilted four-sided platform made of holographic glass, holographic film, or a combination of both. It utilizes video sources of two-dimensional objects captured from four different angles, which are then refracted at a 45-degree angle and converged to form a three-dimensional image with sensory dimensions. Alternatively, transparent panels such as acrylic can be used instead of holographic glass to create the four-sided pseudo-holographic projection.

[0061] It should be noted that the four-sided pseudo-holographic projection used in this embodiment of the invention is low in cost and has a good projection effect. It can be automatically assembled and disassembled. When not in-vehicle charging, the holographic projection device is laid flat and embedded in the vehicle roof. When projection begins, it automatically assembles into a four-sided platform, thereby reducing space waste. Figure 3 and Figure 4 As shown

[0062] Optionally, in embodiment one of the present invention, the projection direction of the first holographic display device 11 and the second holographic display device 21 can be downward projection of the display screen, such as... Figure 3 Alternatively, the display screen can project upwards, such as... Figure 6As shown. The projection direction will not affect the final imaging effect, but in order to protect the holographic display device in rainy or snowy weather and avoid adverse effects such as damage to the device, the projection method with the screen facing downward should be selected.

[0063] Based on the above, this embodiment of the invention, by combining a holographic display device with a flexible connection device, can better warn vehicles approaching from all directions while the vehicle is charging. Specifically, the holographic display device and the flexible connection device interact. The holographic display device is placed on the roof of the vehicle, which avoids the safety problem caused by insufficient light at night, where the spring-loaded barrier between vehicles may not be easily observed. The spring device can more directly deter and warn against vehicles cutting in or overtaking, thus ensuring that vehicles traveling on both sides will not interfere with the charging process, even when the warning effect of the holographic display device is weaker during the day compared to at night.

[0064] In an exemplary embodiment, after controlling the first holographic display device 11 to display a first holographic image and the second holographic display device 21 to display a second holographic image, the method further includes: monitoring whether a fault event occurs during the mutual charging process between the first vehicle 1 and the second vehicle 2, wherein the fault event includes at least one of the following: the elastic connection device 3 is disconnected, or the first holographic display device 11 or the second holographic display device 21 malfunctions; if the fault event is detected, sending a parking instruction message to the first vehicle 1 and the second vehicle 2 to instruct the first vehicle 1 and the second vehicle 2 to stop and continue mutual charging.

[0065] Optional, such as Figure 9 As shown, this embodiment of the invention uses a vehicle control system to control and monitor the holographic display device and the flexible connection device 3. Both the first vehicle 1 and the second vehicle 2 can be equipped with a vehicle control system, which can control and monitor the holographic display device and the flexible connection device 3 on both vehicles. Optionally, the vehicle control systems on the first vehicle 1 and the second vehicle 2 can also monitor and control only their respective vehicles. For example, the vehicle control system on the first vehicle 1 monitors the spring connection status on the first vehicle 1 and the first holographic display device 11 on the roof of the first vehicle 1; then, through information interaction between the first vehicle 1 and the second vehicle 2, it determines the device status of the other vehicle (the other vehicle for the first vehicle is the second vehicle, and vice versa). The device status includes, but is not limited to, whether the holographic display device is successfully turned on, whether a display malfunction has occurred, whether a vehicle malfunction event has occurred, and the vehicle's battery level.

[0066] Understandably, once the flexible connection device 3 is connected, the holographic display device is projecting normally, and the first vehicle 1 and the second vehicle 2 are already engaged in mutual charging while driving, the vehicle control system in this embodiment of the invention will monitor the display status of the holographic display device and the connection status of the flexible connection device in real time throughout the entire charging process. If any malfunction is detected in the display status of the holographic display device or the connection status of the flexible connection device 3, the driver will be notified to stop driving, and the vehicle will be stopped for mutual charging if it is safe to do so.

[0067] Furthermore, in this embodiment of the invention, when both Scheme 1 and Scheme 2 in the above embodiments are used simultaneously, the control process of the vehicle control system for the entire vehicle charging process is as follows: Figure 10 As shown, it includes the following steps:

[0068] Step S1001: Confirm to perform vehicle-to-vehicle charging;

[0069] Step S1002: Determine whether the connection device (i.e., the flexible connection device 3) between the front and rear vehicles (i.e., the first vehicle 1 and the second vehicle 2) is complete. If the connection is not complete, proceed to step S1003; if the connection is complete, proceed to step S1004.

[0070] Step S1003: Report connection failure, end.

[0071] Step S1004: Turn on the holographic projection device, which is equivalent to the holographic display device in the above embodiment, and wait for the device to respond.

[0072] Step S1005: Select the image to be projected on the display screen.

[0073] Step S1006: Determine if the device is projecting normally. If the projection is abnormal, proceed to step S1007; if the projection is normal, proceed to step S1008.

[0074] Step S1007: Report a projection device malfunction, end.

[0075] Step S1008: Perform vehicle charging.

[0076] Step S1009: Determine whether to end vehicle charging. If it is determined that the charging has ended, proceed to step S1010; if it is determined that the charging has not ended, proceed to step S1008.

[0077] Step S1010: Turn off the holographic projection device, end.

[0078] In an exemplary embodiment, after activating the first holographic display device and the second holographic display device, the method further includes: confirming whether a first response message from the first holographic display device 11 and a second response message from the second holographic display device 21 are received within a preset time interval, wherein the first response message indicates that the first holographic display device 11 has been successfully activated, and the second response message indicates that the second holographic display device 21 has been successfully activated; and selecting the first holographic image and the second holographic image from a holographic image library upon receiving the first response message and / or the second response message.

[0079] It is understandable that both the first vehicle 1 and the second vehicle 2 are equipped with holographic display devices. To ensure the driving safety of both vehicles during the mutual charging process, both the first holographic display device 11 and the second holographic display device 21 need to be able to turn on normally and be in a normal holographic display state during operation. Therefore, during the activation phase, it can be determined by whether the first response message and the second response message are received simultaneously within a preset time interval. If they are received simultaneously, the activation is normal.

[0080] Specifically, if a target event occurs within the preset time interval, a holographic display device fault information is reported, wherein the target event includes one of the following:

[0081] Only the first response message is received within the preset time interval;

[0082] Only the second response message is received within the preset time interval;

[0083] No response message is received within the preset time interval, wherein the any response message is either the first response message or the second response message;

[0084] An error response message is received within the preset time interval, wherein the error response message is used to indicate that the first response message and / or the second response message is an error response message.

[0085] During the activation phase, if either the first response message or the second response message has been received within a preset time interval, the first holographic image and the second holographic image to be displayed can be selected, saving waiting and selection time. Optionally, the image selection operation can be performed by either a first target object bound to the first vehicle or a second target object bound to the second vehicle, or the first target object can be the first holographic display device on the roof of the first vehicle to select the first display image, etc. This embodiment of the invention does not limit this.

[0086] In an exemplary embodiment, after controlling the first holographic display device 11 to display a first holographic image and the second holographic display device 21 to display a second holographic image, the process includes: determining whether a display failure has occurred in the holographic display device, wherein the holographic display device includes the first holographic display device 11 and the second holographic display device 21, and the display failure includes at least one of the following: the holographic display device cannot display the holographic image, or the holographic display device displays the holographic image incompletely, wherein the holographic image includes the first holographic image and the second holographic image; and, in the event of a display failure in the holographic display device, reporting display failure information.

[0087] That is, to strictly ensure the safety of cross-charging while driving, before actual cross-charging, the vehicle control system can perform strict holographic image display detection on the holographic display device after it starts displaying the image. Optionally, a display threshold can be set for incomplete display of the holographic image: for example, if the incomplete display exceeds 30% of the holographic image, a display fault information needs to be reported.

[0088] In an exemplary embodiment, after controlling the first holographic display device 11 to display a first holographic image and the second holographic display device 21 to display a second holographic image, the method further includes: confirming that the first vehicle 1 and the second vehicle 2 have ended the vehicle mutual charging state under the condition of satisfying preset conditions, wherein the preset conditions include at least one of the following: determining that the battery level of the first vehicle 1 is not higher than a first threshold, or the battery level of the second vehicle 2 is higher than a second threshold, wherein the first vehicle 1 is a charging vehicle, the second vehicle 2 is a vehicle being charged, the first threshold is a battery level threshold that satisfies the safe operation of the first vehicle 1, and the second threshold is a battery level threshold that satisfies the safe operation of the second vehicle 2; determining that a charging end command from a first target object has been received, and a confirmation end command from a second target object has been received, wherein the first target object is bound to the first vehicle 1, the second target object is bound to the second vehicle 2, the first vehicle 1 is a charging vehicle, and the second vehicle 2 is a vehicle being charged.

[0089] Optionally, this embodiment of the invention also provides a scheme for determining whether vehicle-to-vehicle charging has ended based on preset conditions. Specifically, preset condition 1: The electric vehicle in this embodiment of the invention is equipped with a power threshold to maintain the safe operation of the electric vehicle, which is equivalent to the first threshold and the second threshold in the above embodiment. Different electric vehicles may have different power thresholds for safe operation. The first vehicle 1, as the charging vehicle that outputs electrical energy, must charge the second vehicle 2 while ensuring its own safe operation. Therefore, if during the charging process, the power of both the first vehicle 1 and the second vehicle 2 is exactly above the safety protection threshold, that is, the first vehicle 1 still has surplus power and the second vehicle 2 is fully charged, which is equivalent to "the power of the second vehicle 2 is higher than the second threshold", then vehicle-to-vehicle charging can end. If the power cannot be satisfied by being above the first threshold and the second threshold respectively, when the power of the first vehicle 1 is no higher than the first threshold of the first vehicle, then vehicle-to-vehicle charging also ends. At this time, the vehicle can be rearranged to charge the second vehicle.

[0090] Preset condition 2: The charging termination can be determined based on the charging termination command initiated by the first target object driving the first vehicle 1 and the termination confirmation command selected by the second target object driving the second vehicle 2. Specifically, the first target object selects to terminate charging on the in-vehicle display screen, thereby initiating the charging termination command; the charging termination command will trigger a confirmation selection box to appear on the in-vehicle display screen of the second vehicle. If the second target object clicks the confirmation selection box, the termination confirmation command is triggered, thereby ending the charging termination.

[0091] In an exemplary embodiment, after confirming that the first vehicle and the second vehicle have ended the vehicle mutual charging state, the method further includes: controlling the first holographic display device and the second holographic display device to simultaneously display a third holographic image, wherein the third holographic image is used to indicate that the first vehicle and the second vehicle disconnect after a preset time period; disconnecting the charging cable; and turning off the first holographic display device 11 and the second holographic display device 21.

[0092] It should be noted that, in this embodiment of the invention, after confirming the end of vehicle-to-vehicle charging, a third holographic image will be displayed via a holographic display device to warn surrounding vehicles that the first and second vehicles are about to lose connection. The preset time period can be selected as 1-2 minutes. When using a flexible connection device, the flexible connection device, charging cable, and holographic display device are simultaneously disconnected. After the flexible connection device and charging cable are disconnected, they will automatically reconnect to the first and / or second vehicles.
