Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or devices.

[0046] The present application discloses a method and system for assisting charging between new energy vehicles, which is useful for increasing the amount of electricity that can be charged into the battery by the solar panels installed on the roof of the new energy vehicle. A detailed description is provided below with reference to the accompanying drawings.

[0047] See also Figure 1 , Figure 1 This is a flow chart of the first embodiment of the charging assistance method between new energy vehicles disclosed in the embodiment of this application. Figure 1 In the charging assistance method between new energy vehicles shown in the figure, the roof of the first new energy vehicle is equipped with a first solar panel, and the first solar panel participates in supplying power to the battery of the first new energy vehicle. The first parking space currently occupied by the first new energy vehicle is located in an open-air parking lot. Figure 1 As shown, the charging assistance method between new energy vehicles may include the following steps:

[0048] 101. The first new energy vehicle detects whether the first current output power of the first solar panel in the first parking space is lower than the target output power; if not, end this process; if so, execute step 102.

[0049] In an embodiment of the present application, if the first parking space is gradually covered by the shadow of trees or buildings over time, the first new energy vehicle can detect that the first current output power of the first solar panel in the first parking space where the first new energy vehicle is located is lower than the target output power.

[0050] 102. The first new energy vehicle determines a second new energy vehicle from the open-air parking lot; a second current output power of a second solar panel equipped on the roof of the second new energy vehicle in a second parking space where the second new energy vehicle is located is higher than the target output power.

[0051] In some embodiments, the first new energy vehicle determines the second new energy vehicle from the open-air parking lot, including:

[0052] The first new energy vehicle turns on the wireless access hotspot (such as a Wi-Fi hotspot) of the first new energy vehicle and requests other new energy vehicles in the open-air parking lot to access the wireless access hotspot; for example, the first new energy vehicle can send an access request to surrounding vehicles scanned by the wireless access hotspot, and the access request is used to request other new energy vehicles in the open-air parking lot to access the wireless access hotspot; for a certain vehicle, after hearing the access request, it can detect whether its current parking space is located in the open-air parking lot. If it is, it can further check whether it is a new energy vehicle. If it is, it responds to the access request to access the wireless access hotspot; on the contrary, if it is not a new energy vehicle, it refuses to access the wireless access hotspot;

[0053] The first new energy vehicle determines, from among the other new energy vehicles that have successfully accessed the wireless access hotspot, several new energy vehicles that have second solar panels on their roofs. For example, the first new energy vehicle may send an inquiry message to each of the other new energy vehicles that have successfully accessed the wireless access hotspot, the inquiry message being used to inquire whether the roof of the new energy vehicle is configured with a second solar panel. If the new energy vehicle returns response information indicating that the roof of the new energy vehicle is configured with a second solar panel to the first new energy vehicle, the first new energy vehicle determines that the new energy vehicle is the new energy vehicle that has the second solar panel on its roof, thereby enabling the determination of several new energy vehicles that have second solar panels on their roofs from among the other new energy vehicles that have successfully accessed the wireless access hotspot.

[0054] The first new energy vehicle determines a new energy vehicle from the multiple new energy vehicles as the second new energy vehicle; wherein, among the multiple new energy vehicles, the second solar panel equipped on the roof of the second new energy vehicle has the highest second current output power at the second parking space where the second new energy vehicle is located; for example, the multiple new energy vehicles include new energy vehicle X1, new energy vehicle X2, new energy vehicle X3, new energy vehicle X4 and new energy vehicle X5; wherein, the second solar panel equipped on the roof of the new energy vehicle X1 has a second current output power P1 at the second parking space where the new energy vehicle X1 is located, and the second solar panel equipped on the roof of the new energy vehicle X2 has a second current output power P2 at the second parking space where the new energy vehicle X1 is located. The second current output power of the second parking space in which the new energy vehicle X2 is located is P2, the second current output power of the second solar panel on the roof of the new energy vehicle X3 in the second parking space in which the new energy vehicle X3 is located is P3, the second current output power of the second solar panel on the roof of the new energy vehicle X4 in the second parking space in which the new energy vehicle X4 is located is P4, and the second current output power of the second solar panel on the roof of the new energy vehicle X5 in the second parking space in which the new energy vehicle X5 is located is P5; and if P1>P3>P2>P4>P5, then the first new energy vehicle may determine the new energy vehicle X1 as the second new energy vehicle. In other embodiments, if P1=P3>P2>P4>P5, then the first new energy vehicle may randomly determine the new energy vehicle X1 or the new energy vehicle X3 as the second new energy vehicle.

[0055] 103. The first new energy vehicle sends a parking space exchange charging request to the second new energy vehicle, where the parking space exchange charging request carries the location information of the first parking space.

[0056] Exemplarily, the location information of the first parking space may be a unique parking space number of the first parking space, or the location information of the first parking space may be the geographic coordinates of the first parking space.

[0057] 104. The second new energy vehicle responds to the transposition charging request and detects whether the current power level of the battery of the second new energy vehicle powered by the second solar panel is higher than the power level set by the owner of the second new energy vehicle; if not, execute step 105; if so, execute steps 106-109.

[0058] Among them, the power level set by the owner of the second new energy vehicle can be set by the owner of the second new energy vehicle according to actual needs, and is not limited in this embodiment of the present application.

[0059] 105. The second new energy vehicle sends a response of disagreement with the position-swap charging to the first new energy vehicle, and ends this process.

[0060] 106. The second new energy vehicle sends a parking space swap charging consent response to the first new energy vehicle, and automatically drives out of the second parking space and drives towards the first parking space.

[0061] In an embodiment of the present application, the second new energy vehicle can automatically drive out of the second parking space and drive towards the first parking space based on an automatic driving strategy.

[0062] 107. In response to the parking change charging consent response, the first new energy vehicle automatically drives out of the first parking space and drives towards the second parking space.

[0063] In an embodiment of the present application, the first new energy vehicle can automatically drive out of the first parking space and drive towards the second parking space based on an automatic driving strategy.

[0064] 108. When the second new energy vehicle automatically drives to the first parking space and recognizes that the first parking space is vacant, the second new energy vehicle automatically drives into the first parking space to continue solar charging.

[0065] 109. When the first new energy vehicle automatically drives to the second parking space and recognizes that the second parking space is vacant, the first new energy vehicle automatically drives into the second parking space to continue solar charging.

[0066] It is understandable that the execution order of the above steps 108 and 109 can be interchanged, or the above steps 108 and 109 can be executed simultaneously, which is not limited in the embodiment of the present application.

[0067] It can be seen that implementation Figure 1 The charging assistance method between new energy vehicles shown is beneficial to increasing the amount of electricity charged into the battery by the first solar panel equipped on the roof of the first new energy vehicle, thereby helping to increase the cruising range of the first new energy vehicle.

[0068] See also Figure 2 , Figure 2 This is a flow chart of the second embodiment of the charging assistance method between new energy vehicles disclosed in the embodiment of this application. Figure 2 In the charging assistance method between new energy vehicles shown in the figure, the roof of the first new energy vehicle is equipped with a first solar panel, and the first solar panel participates in supplying power to the battery of the first new energy vehicle. The first parking space currently occupied by the first new energy vehicle is located in an open-air parking lot. Figure 2 As shown, the charging assistance method between new energy vehicles may include the following steps:

[0069] 201. When the driver's left hand and right hand simultaneously hold the circular steering wheel of the first new energy vehicle and a first gripping force applied by the left hand at a first designated position of the circular steering wheel and a second gripping force applied by the right hand at a second designated position of the circular steering wheel both exceed a preset gripping force, the length of the steering wheel arc passed by the left hand when the left hand, while holding the circular steering wheel, slides from the first designated position along the circular steering wheel toward the right hand held at the second designated position and stops sliding is detected.

[0070] 202. The first new energy vehicle determines whether the steering wheel arc length exceeds a specified arc length. If not, execute step 203; if so, execute steps 204-205.

[0071] In an embodiment of the present application, the first new energy vehicle can detect, through sensors embedded on the circumference of the circular steering wheel, the length of the steering wheel arc that the left hand has traveled through when the left hand, while holding the circular steering wheel, stops sliding from the first designated position along the circular steering wheel toward the right hand, which is held at the second designated position. In the process of sliding from the first designated position along the circular steering wheel toward the right hand, which is held at the second designated position, while holding the circular steering wheel, the left hand sequentially touches a plurality of sensors on the circumference of the circular steering wheel, and the first new energy vehicle can identify, based on the positions of the touched plurality of sensors, the length of the steering wheel arc that the left hand has traveled through when the left hand, while holding the circular steering wheel, stops sliding from the first designated position along the circular steering wheel toward the right hand, which is held at the second designated position, while holding the circular steering wheel.

[0072] Among them, the implementation of the above-mentioned embodiment allows the driver to easily and flexibly set the target output power corresponding to the first solar panel equipped on the roof of the first new energy vehicle by keeping both hands on the circular steering wheel during the driving of the first new energy vehicle. This not only improves driving safety, but also enhances the intelligence and driving experience of the first new energy vehicle.

[0073] 203 . The first new energy vehicle uses the preset minimum output power of the first solar panel as the target output power and jumps to execute step 205 .

[0074] 204. The first new energy vehicle obtains the arc length difference between the steering wheel arc length and the specified arc length, obtains the output power change that is directly proportional to the arc length difference, and obtains the sum of the output power change and the preset first solar panel minimum output power as the target output power.

[0075] It can be understood that, when the arc length difference is larger, the output power variation is larger; conversely, when the arc length difference is smaller, the output power variation is smaller.

[0076] In addition, implementing the above step 204 is conducive to increasing the probability that the first new energy vehicle detects that the first current output power of the first solar panel in the first parking space is lower than the target output power, thereby helping to increase the probability that the first new energy vehicle executes the position change for solar charging.

[0077] 205. The first new energy vehicle detects whether the first current output power of the first solar panel in the first parking space is lower than the target output power; if not, end this process; if so, execute steps 206 to 208.

[0078] 206. The first new energy vehicle determines a second new energy vehicle from the open-air parking lot; a second current output power of a second solar panel equipped on the roof of the second new energy vehicle in a second parking space where the second new energy vehicle is located is higher than the target output power.

[0079] 207. The first new energy vehicle sends a parking space exchange charging request to the second new energy vehicle, where the parking space exchange charging request carries the location information of the first parking space.

[0080] 208. The second new energy vehicle responds to the transposition charging request by detecting whether the current power level of the battery of the second new energy vehicle powered by the second solar panel is higher than the power level set by the owner of the second new energy vehicle; if not, execute step 209; if so, execute steps 210-213.

[0081] 209. The second new energy vehicle sends a response of disagreement with the position-swap charging to the first new energy vehicle, and ends this process.

[0082] 210. The second new energy vehicle sends a parking space swap charging consent response to the first new energy vehicle, and automatically drives out of the second parking space and toward the first parking space.

[0083] 211. In response to the parking change charging consent response, the first new energy vehicle automatically drives out of the first parking space and drives towards the second parking space.

[0084] 212. When the second new energy vehicle automatically drives to the first parking space and identifies that the first parking space is vacant, it automatically drives into the first parking space to continue solar charging and sends a first notification message to the electronic device of the owner of the second new energy vehicle. The first notification message includes at least the location information of the first parking space.

[0085] 213. When the first new energy vehicle automatically drives to the second parking space and identifies that the second parking space is vacant, it automatically drives into the second parking space to continue solar charging and sends a second notification message to the electronic device of the owner of the first new energy vehicle, where the second notification message includes at least the location information of the second parking space.

[0086] Among them, implementing the above-mentioned steps 212 and 213 can also facilitate the owner of the second new energy vehicle to quickly find the second new energy vehicle in the open-air parking lot; and can also facilitate the owner of the first new energy vehicle to quickly find the first new energy vehicle in the open-air parking lot.

[0087] It can be seen that implementation Figure 2 The charging assistance method between new energy vehicles shown is beneficial to increasing the amount of electricity charged into the battery by the first solar panel equipped on the roof of the first new energy vehicle, thereby helping to increase the cruising range of the first new energy vehicle.

[0088] See also Figure 3 , Figure 3 This is a flow chart of the third embodiment of the charging assistance method between new energy vehicles disclosed in the embodiment of this application. Figure 3 In the charging assistance method between new energy vehicles shown in the figure, the roof of the first new energy vehicle is equipped with a first solar panel, and the first solar panel participates in the operation of supplying power to the battery of the first new energy vehicle. The first new energy vehicle is also provided with a first UWB (Ultra-Wide Band) antenna. The first parking space currently occupied by the first new energy vehicle is located in an open-air parking lot. Figure 3 As shown, the charging assistance method between new energy vehicles may include the following steps:

[0089] 301. When the driver's left hand and right hand simultaneously hold the circular steering wheel of the first new energy vehicle and a first gripping force applied by the left hand at a first designated position of the circular steering wheel and a second gripping force applied by the right hand at a second designated position of the circular steering wheel both exceed a preset gripping force, the length of the steering wheel arc passed by the left hand when the left hand stops sliding from the first designated position along the circular steering wheel toward the right hand held at the second designated position while holding the circular steering wheel is detected.

[0090] 302. The first new energy vehicle determines whether the steering wheel arc length exceeds a specified arc length. If not, execute step 303; if so, execute steps 304-305.

[0091] 303 . The first new energy vehicle uses the preset minimum output power of the first solar panel as the target output power and jumps to execute step 305 .

[0092] 304. The first new energy vehicle obtains the arc length difference between the steering wheel arc length and the specified arc length, obtains the output power change that is directly proportional to the arc length difference, and obtains the sum of the output power change and the preset first solar panel minimum output power as the target output power.

[0093] 305. The first new energy vehicle detects whether the first current output power of the first solar panel in the first parking space is lower than the target output power; if not, end this process; if so, execute step 306.

[0094] In an embodiment of the present application, if the first parking space is gradually covered by the shadow of trees or buildings over time, the first new energy vehicle can detect that the first current output power of the first solar panel in the first parking space where the first new energy vehicle is located is lower than the target output power.

[0095] 306.

[0096] 307. The first new energy vehicle determines a second new energy vehicle from the open-air parking lot; a second current output power of a second solar panel equipped on the roof of the second new energy vehicle in a second parking space where the second new energy vehicle is located is higher than the target output power.

[0097] 308. The first new energy vehicle sends a parking space exchange charging request to the second new energy vehicle, where the parking space exchange charging request carries the location information of the first parking space.

[0098] 309.

[0099] 310. The second new energy vehicle sends a response of disagreement with the position-swap charging to the first new energy vehicle, and ends this process.

[0100] 311 The second new energy vehicle sends the first interactive information to the electronic device of the owner of the second new energy vehicle. The first interactive information includes at least a first field and a second field. The first field is used to indicate that the current power of the battery of the second new energy vehicle is higher than the power set by the owner of the second new energy vehicle; the second field is used to ask the owner of the second new energy vehicle whether he agrees to charge in a different position.

[0101] 312. The second new energy vehicle detects whether it has received the second interactive information sent by the electronic device of the owner of the second new energy vehicle, indicating that the owner of the second new energy vehicle agrees to the charging swap; if not, return to step 310; if received, execute steps 313-316.

[0102] The implementation of the above steps 311 and 312 is beneficial to improving the accuracy of the charging exchange between the first new energy vehicle and the second new energy vehicle.

[0103] 313. The second new energy vehicle sends a parking space swap charging consent response to the first new energy vehicle, and automatically drives out of the second parking space and toward the first parking space.

[0104] 314. The first new energy vehicle automatically drives out of the first parking space and toward the second parking space in response to the charge swap consent response; and, while driving toward the second parking space, if it is detected that the distance between the first UWB antenna and the second UWB antenna provided on any other vehicle in the open-air parking lot is less than or equal to a preset distance, the first UWB antenna is controlled to send a notification message carrying the location information of the first parking space and describing that the current output power of the solar panel in the first parking space is lower than the target output power to the second UWB antenna provided on any other vehicle, so that any other vehicle learns, based on the notification message, that the current output power of the solar panel in the first parking space is lower than the target output power.

[0105] Among them, for any other car, after receiving the notification information through the second UWB antenna set by any other car, it can be obtained that the output power of the solar panel in the first parking space is lower than the target output power. In this way, any other car can exclude the first parking space when it needs to change seats for solar charging, which is conducive to any other car quickly finding a parking space where the output power of the solar panel is higher than the target output power.

[0106] 315. When the second new energy vehicle automatically drives to the first parking space and identifies that the first parking space is vacant, it automatically drives into the first parking space to continue solar charging and sends a first notification message to the electronic device of the owner of the second new energy vehicle. The first notification message includes at least the location information of the first parking space.

[0107] 316. When the first new energy vehicle automatically drives to the second parking space and identifies that the second parking space is vacant, it automatically drives into the second parking space to continue solar charging and sends a second notification message to the electronic device of the owner of the first new energy vehicle, where the second notification message includes at least the location information of the second parking space.

[0108] It can be seen that implementation Figure 3 The charging assistance method between new energy vehicles shown is beneficial to increasing the amount of electricity charged into the battery by the first solar panel equipped on the roof of the first new energy vehicle, thereby helping to increase the cruising range of the first new energy vehicle.

[0121] As an optional implementation, Figure 4 In the charging assistance system between the new energy vehicles shown:

[0122] The second new energy vehicle 402 is also used to send a first interactive message to the electronic device of the owner of the second new energy vehicle 402 after detecting that the current power of the battery of the second new energy vehicle 402 powered by the second solar panel is higher than the power set by the owner of the second new energy vehicle 402. The first interactive message includes at least a first field and a second field. The first field is used to indicate that the current power of the battery of the second new energy vehicle 402 is higher than the power set by the owner of the second new energy vehicle 402; the second field is used to inquire whether the owner of the second new energy vehicle 402 agrees to the charging switch; and detect whether the second interactive message sent by the electronic device of the owner of the second new energy vehicle 402 is received to indicate that the owner of the second new energy vehicle 402 agrees to the charging switch; if received, execute the step of sending the charging switch consent response to the first new energy vehicle 401.

[0123] As an optional implementation, Figure 4 In the charging assistance system between new energy vehicles shown, the first new energy vehicle 401 determines the second new energy vehicle 402 from the open-air parking lot in the following manner:

[0124] The first new energy vehicle 401 turns on the wireless access hotspot of the first new energy vehicle 401 and requests other new energy vehicles in the open-air parking lot to access the wireless access hotspot;

[0125] The first new energy vehicle 401 determines a number of new energy vehicles with second solar panels configured on their roofs from other new energy vehicles that have successfully accessed the wireless access hotspot;

[0126] The first new energy vehicle 401 determines a new energy vehicle from the several new energy vehicles as the second new energy vehicle 402; wherein, among the several new energy vehicles, the second solar panel equipped on the roof of the second new energy vehicle 402 has the highest second current output power in the second parking space where the second new energy vehicle 402 is located.

[0127] As an optional implementation, Figure 4 In the charging assistance system between new energy vehicles shown, before the first new energy vehicle 401 detects whether the first current output power of the first solar panel at the first parking space is lower than the target output power, it is further configured to:

[0130] As an optional implementation, Figure 4 In the charging assistance system between new energy vehicles shown, the first new energy vehicle 401 is provided with a first UWB antenna. After the first new energy vehicle 401 responds to the swap charging consent response and automatically drives out of the first parking space and drives towards the second parking space, it is also used to:

[0131] When driving towards the second parking space, detect whether the distance between the first UWB antenna and the second UWB antenna set on any other car in the open-air parking lot is less than or equal to a preset distance; if so, control the first UWB antenna to send a notification message carrying the location information of the first parking space to the second UWB antenna set on any other car, which is used to describe that the current output power of the solar panel in the first parking space is lower than the target output power, so that any other car learns from the notification information that the current output power of the solar panel in the first parking space is lower than the target output power.
