[0021] When the charging current at the charging port exceeds a preset threshold, the control unit controls the corresponding fast disconnect switch to disconnect the charging port from all the power supply units.

[0022] A second aspect of this application provides a control device for a flying car power distribution system, the flying car power distribution system including a power supply bus main line and multiple loads electrically connected to the power supply bus main line, the device comprising:

[0027] In some implementations, the isolated execution module includes:

[0049] Embodiments of this application will now be described in more detail with reference to the accompanying drawings. While embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.

[0050] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The singular forms “a,” “the,” and “the” used in this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0051] It should be understood that although the terms "first," "second," "third," etc., may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0052] In related technologies, the fault isolation accuracy of the power distribution system of flying cars is low, which can easily isolate faulty operating units together with non-faulty operating units. This may cause the flying car to fail to operate normally, which in turn may affect the overall safety of the flying car.

[0053] To address the aforementioned issues, this application provides a control method for the power distribution system of a flying car, which can effectively ensure accurate isolation of faults, prevent fault spread, and improve the overall safety performance of the flying car.

[0054] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0055] In the control method for the flying car power distribution system of this application, the flying car power distribution system includes a main power supply bus and multiple loads electrically connected to the main power supply bus. The loads may include power units. A power unit can refer to a working unit that provides flight power to the flying car, such as a working unit composed of rotating propellers and related drive components. Alternatively, the loads may include other working units besides the power unit, which will not be elaborated here. The main power supply bus corresponds to the main power supply line of the power distribution system, and the loads are connected to the main power supply bus.

[0056] Figure 1 This is a flowchart illustrating the control method for the power distribution system of a flying car as shown in an embodiment of this application.

[0057] See Figure 1 The flying car power distribution system control method of this application includes,

[0058] S110 pre-groups all loads according to preset rules to obtain at least two different types of load groups, and configures different types of isolation devices for different types of load groups.

[0059] In this step, all loads on the two sections of the power supply bus are pre-grouped according to preset rules, and different types of isolation devices are configured for different types of load groups.

[0060] Each type of load group can have at least one group.

[0061] S120 performs different isolation procedures based on the different types of isolation devices configured when a fault is detected in any load group.

[0062] In this step, when a fault is detected in any load group, different isolation processes are performed using pre-configured isolation devices. It should be understood that different types of isolation devices employ different isolation processes. Specifically, the isolation devices in this application may include at least two different types.

[0063] In this embodiment, the flying car power distribution system control method of this application divides the loads in the power distribution system into multiple different types of load groups according to preset rules, and configures different types of isolation devices for different types of loads. When a fault such as a short circuit or open circuit exists in any load group, the pre-configured isolation devices accurately isolate the faulty load group, preventing the fault from spreading and ensuring the normal operation of the remaining load groups. This allows the flying car to maintain normal operation, thereby significantly improving the overall safety performance of the flying car.

[0064] Figure 2 This is another schematic flowchart illustrating the control method of the power distribution system of a flying car as shown in the embodiments of this application.

[0065] See Figure 2 The flying car power distribution system control method of this application includes,

[0066] S210, all loads are pre-grouped according to the rules necessary for maintaining the normal operation of the flying car, resulting in a first load group of necessary types and a second load group of non-necessary types; wherein, the first load group is equipped with a fast disconnect switch and the second load group is equipped with a non-fast disconnect switch.

[0067] In this step, all loads are pre-grouped according to rules regarding their necessity for maintaining the normal operation of the flying car, resulting in a first load group of necessary types and a second load group of non-necessary types. It should be understood that necessary types can refer to those required for maintaining the flying car's normal flight, while non-necessary types can refer to those not required for normal flight. Specifically, a fast-isolating switch is configured for the first load group to perform isolation processing, and a non-fast-isolating switch is configured for the second load group to perform isolation processing.

[0068] Fast-disconnecting switches can be solid-state relays, transistors, field-effect transistors, or a combination of these components. Under the control of a control unit, fast-disconnecting switches can switch between on and off states, offering advantages such as fast disconnection speed, low loss, small weight, high reliability, and recoverability after disconnection. Non-fast-disconnecting switches can be either ordinary fuses or smart fuses. Non-fast-disconnecting switches are low-cost and non-recoverable after disconnection; therefore, using them to isolate non-essential loads can reduce the impact on the driving safety of flying cars.

[0069] The first load group and the second load group can be in a backup relationship. That is, if either the first load group fails, another second load group can be converted into a necessary first load group, thereby ensuring that the flying car can maintain normal flight. There are at least two first load groups and at least one second load group.

[0070] The load can consist of a power propulsion unit and other load units. The power propulsion unit can refer to the working unit that provides the flight power for the flying car, while other load units can refer to other working units in the power distribution system besides the power propulsion unit, such as detection units, power distribution units, voltage stabilization units, etc.

[0071] Furthermore, during the grouping process, the first load group can consist of the power propulsion units necessary for the normal operation of the flying car. The second load group can consist of power propulsion units not necessary for the normal operation of the flying car, as well as other load units.

[0072] Furthermore, load grouping can also be based on the positional relationship of the loads. Specifically, the load grouping process can take into account the positional symmetry of the loads. The first load group can consist of at least two groups, each of which may include two symmetrically distributed power propulsion units necessary for the normal operation of the flying vehicle. The second load group can consist of at least one group, each of which may include two symmetrically distributed power propulsion units not necessary for the normal operation of the flying vehicle.

[0073] Furthermore, other load units can be distributed across different second load groups based on their relative backup relationships. It should be understood that any two mutually backing load units can be located in different second load groups. This ensures that even if one second load group fails and is isolated, other load units in other second load groups with backup relationships can maintain normal operation.

[0074] As an example, a flying car has six propulsion units (i.e., loads). To ensure the continuous safe flight and landing of the flying car, at least four propulsion units need to operate continuously. When grouping the aforementioned recommended propulsion units, they can be divided into two first load groups that are necessary for maintaining the continuous safe flight and landing of the flying car, and a second load group that is not necessary for maintaining the continuous safe flight and landing of the flying car. Each first load group includes two symmetrically distributed propulsion units. Similarly, the second load group also includes two symmetrically distributed propulsion units.

[0075] As another example, taking the flying car mentioned above as an example, the flying car also includes three other load units. Among the three other load units, there is a backup relationship between two of the other load units. Then, one of the other load units that has a backup relationship among the three other load units can form a second load group with the two power propulsion units that are not necessary for maintaining the continuous safe flight and landing of the flying car. The remaining two other load units are grouped into an independent second load group.

[0076] S220, when a fault is detected in any first load group, the control unit controls a pre-configured fast disconnect switch to disconnect the faulty first load group from the power supply bus main line; or when a fault is detected in any second load group, the control unit controls a pre-configured non-fast disconnect switch to disconnect the faulty second load group from the power supply bus main line.

[0077] In this step, after pre-grouping all loads, fault detection is continuously performed on all load groups. When a fault is detected in any first load group or any second load group, the faulty load group is isolated using a pre-configured isolation device. Specifically, when a fault is determined to be in the first load group, the control unit controls a pre-configured fast disconnect switch to disconnect the faulty first load group from the main power supply bus. When a fault is in the second load group, a pre-configured non-fast disconnect switch directly disconnects the faulty second load group from the main power supply bus. It should be understood that the non-fast disconnect switch can generally disconnect automatically after a preset condition is met (such as an instantaneous current increase to a preset value).

[0078] In this system, if any of the first load groups fails and is isolated, a corresponding second load group can be automatically activated to replace the failed first load group, thereby ensuring that the flying car can maintain normal flight. It should be understood that the activated second load group includes at least two symmetrically distributed propulsion units.

[0079] The flying car power distribution system in this application may further include at least two power supply units connected to the main power supply bus. It is understood that a power supply unit can refer to a working unit in the flying car used to provide power. The power supply unit can be a battery or other component capable of providing electrical energy. When the power supply unit is working, it controls the power supply unit to power on and off the entire high-voltage power distribution system via relays, for example, powering on before the flying car takes flight and powering off when the flying car is not flying.

[0080] Figure 3 This is another schematic flowchart illustrating the control method of the power distribution system of a flying car as shown in the embodiments of this application.

[0081] See Figure 3 After performing steps S210 and S220, the flight car power distribution system control method of this application can also perform the following steps:

[0082] S230, pre-group all power supply units to obtain multiple power supply groups; wherein non-fast disconnect switches are configured for each power supply group, and fast disconnect switches are configured between any two power supply groups.

[0083] In this step, all power supply units are pre-grouped, with each power supply unit grouped as an independent group, resulting in multiple independent power supply groups. A non-fast disconnect switch is configured for each power supply group to perform isolation processing. When there are two or more power supply groups, at least one fast disconnect switch is configured between any two power supply groups to ensure the normal operation of other power supply groups in the event of a fault in one power supply group (such as a short circuit).

[0084] Each power supply group can be connected to the main power supply bus via a non-fast disconnect switch. This means that each power supply group can be connected to the main power supply bus at its output port via a non-fast disconnect switch (such as a standard fuse). When a power supply group experiences a fault, such as a short circuit, isolation can be achieved from its output port.

[0085] S240, when a fault is detected in any power supply group, disconnect the faulty power supply group from the main power supply bus by means of a pre-configured non-fast disconnect switch; and / or, control the fast disconnect switches corresponding to the remaining power supply groups to be turned on by means of a control unit.

[0086] In this step, after all power supply groups are pre-grouped, fault detection is continuously performed on all power supply groups. When a fault is detected in any power supply group, the faulty power supply group is disconnected from the main power supply bus via the corresponding non-fast disconnect switch, thereby isolating the faulty power supply group. After the faulty power supply group is isolated, the control unit controls the fast disconnect switches of the remaining power supply groups to be turned on, thus allowing the remaining power supply groups to supply power normally and ensuring the normal operation of the flying car.

[0087] It is understandable that when a short circuit occurs in a power supply unit within a power supply group, it can easily lead to an increase in the current in the main power supply bus. When a fault is detected in any power supply group, the control unit first controls the fast disconnect switches corresponding to the other power supply groups to disconnect, thereby protecting the other power supply groups.

[0088] Furthermore, based on the grouping results, a non-fast disconnecting switch (such as a smart fuse) can be configured in advance in the main power supply bus, between any two power supply groups; when a fault is detected in any power supply group, the corresponding non-fast disconnecting switch in the main power supply bus can be controlled to disconnect, so as to prevent the large current caused by the power supply group fault from causing damage to the main power supply bus.

[0089] In the flying car power distribution system of this application, at least one backup fast disconnect switch is also configured between any two first load groups.

[0090] Figure 4 This is another schematic flowchart illustrating the control method of the power distribution system of a flying car as shown in the embodiments of this application.

[0091] See Figure 4 After performing steps S210 and S230, the flight car power distribution system control method of this application can also perform the following steps:

[0092] S250, at least one backup fast disconnect switch is configured between any two first load groups in advance according to the grouping results, and at least two control units are configured to control a preset number of fast disconnect switches and backup fast disconnect switches respectively.

[0093] In this step, based on all the grouping results in this application, at least one backup fast disconnect switch is configured between any two first load groups in advance, and at least two control units are configured to control a preset number of fast disconnect switches and backup fast disconnect switches respectively. The backup fast disconnect switches are mainly used when the control unit or fast disconnect switch corresponding to a first load group fails, preventing the first load group from connecting to the power supply bus main line via the corresponding fast disconnect switch. In this case, other control units can use the corresponding backup fast disconnect switches to enable the first load group to connect to the power supply bus main line and operate normally.

[0094] The number of fast disconnect switches controlled by any two control units can be the same or different. Specifically, the number of fast disconnect switches controlled by each control unit can be set using pre-defined association rules, such as evenly or alternately distributing them to all control units. Furthermore, the fast disconnect switch corresponding to each first load group is controlled by an independent control unit. For example, if the power distribution system has two first load groups, the fast disconnect switch corresponding to each first load group is controlled by an independent control unit. This minimizes the impact of a failure in any control unit on the normal operation of the flying car, ensuring the safety of the flying car's flight.

[0095] The number of backup fast disconnect switches controlled by any two control units can be the same or different. A single backup fast disconnect switch can be controlled by one independent control unit or by two or more control units simultaneously. For example, a power distribution system may have a backup fast disconnect switch that can be controlled by two control units simultaneously. If either control unit fails, the other control unit can control the backup fast disconnect switch to conduct, thereby ensuring the normal operation of the first load group in the flying car.

[0096] S260, when a fault is detected in any control unit, controls the corresponding preset number of fast disconnect switches and all backup fast disconnect switches to be turned on through the other control units.

[0097] In this step, after the control unit is pre-configured, all control units are continuously monitored. When any control unit fails, it means that the fast disconnect switch it controls has failed. Then, the other control units control the corresponding fast disconnect switches and all backup fast disconnect switches to ensure that all first load groups work normally.

[0098] Figure 5 This is another schematic flowchart illustrating the control method of the power distribution system of a flying car as shown in the embodiments of this application.

[0099] See Figure 5 In the flying car power distribution system of this application, the flying car power distribution system may also include a charging port. It should be understood that the charging port can be connected to any location on the main power supply bus or to a branch formed by the connection between the first load groups.

[0100] After performing steps S210 and S230 above, the flight car power distribution system control method of this application may also perform the following steps:

[0101] S270, at least one fast disconnect switch is pre-configured between the charging port and any power supply unit according to the access location of the charging port.

[0102] In this step, at least one fast disconnect switch is configured between the charging port and any power supply unit in advance, based on the access location of the charging port in the power distribution system.

[0103] Specifically, at least one fast-isolating switch corresponding to the power supply unit can be configured according to the charging current path of the charging port. In other words, at least one fast-isolating switch is provided between the charging port and any power supply unit.

[0104] S280, when it detects that the charging current of the charging port exceeds a preset threshold, controls the corresponding fast isolation switch through the control unit to disconnect the charging port from all power supply units.

[0105] In this step, when a charging port malfunctions—that is, when a surge in charging current is detected exceeding a preset threshold—the control unit activates the corresponding fast-isolating switch to disconnect the charging port from all power supply units, thus preventing damage to the power supply units. Alternatively, after the charging port returns to normal operation, the corresponding fast-isolating switch can be reactivated to restore the connection between the charging port and all power supply units, thereby restoring the charging function for all power supply units.

[0106] The charging port can be configured with at least one fast disconnect switch or at least one non-fast disconnect switch between the charging port and the first load group and the second load group. In this way, when the charging port fails, the connection between the charging port and the first load group and the second load group can be disconnected by the corresponding fast disconnect switch or non-fast disconnect switch.

[0107] Figure 6 This is another schematic flowchart illustrating the control method of the power distribution system of a flying car as shown in the embodiments of this application.

[0108] See Figure 6 In this application, the aforementioned steps S210, S230, and S270 can be performed simultaneously, followed by the aforementioned step S250, and then the aforementioned steps S220, S240, S260, and S280 can be performed simultaneously. In other words, the flying car power distribution system control method of this application can first pre-group the loads and power supply units in the power distribution system, then configure corresponding isolation devices according to the grouping results, and then continuously detect faults. After detecting a fault in a corresponding group, the faulty group is isolated using pre-configured isolation devices (i.e., fast disconnect switches or non-fast disconnect switches).

[0109] It should be noted that in this application, the same fast-disconnecting switch or non-fast-disconnecting switch can be used simultaneously to perform isolation processing on different faulty groups. That is, as mentioned above, different isolation devices are configured according to different groups. In different isolation processing steps, such as steps S220, S240, S260, and S280, the isolation devices of the same type performing the isolation processing can be the same fast-disconnecting switch or non-fast-disconnecting switch. Furthermore, in this application, there can be only a single fault; that is, there is one and only one fault in all load groups, power supply groups, control units, and charging ports.

[0110] In this embodiment, the flying car power distribution system control method of this application pre-groups the loads in the flying car into first and second load groups based on whether they are necessary to maintain normal operation, and configures fast and non-fast disconnect switches respectively. When a fault is detected in the first load group, the control unit controls the fast disconnect switch to disconnect its connection with the main power supply bus; when a fault is detected in the second load group, the non-fast disconnect switch disconnects. Through the above control method, the fault isolation targeting and efficiency can be effectively improved, thereby optimizing the stability and reliability of the power distribution system. Furthermore, by effectively reducing the number of fast disconnect switches, the overall cost and complexity of the power distribution system can also be reduced. The flying car power distribution system control method of this application also pre-configures at least two control units according to the grouping results to control a preset number of fast disconnect switches and backup fast disconnect switches respectively, realizing the redundancy design of the control units. When a fault is detected in any control unit, the remaining control units can control the corresponding preset number of fast disconnect switches and all backup fast disconnect switches to conduct, effectively avoiding the failure of fast disconnect switches to work properly due to the failure of a single control unit, thereby ensuring the safety performance of the flying car.

[0111] To facilitate understanding of the technical solutions of this application, the following will further describe this application in detail with reference to the system application framework shown in Embodiments 1 and 2. These embodiments are for illustrative purposes only and are not limited to the application scope of this application. Unless otherwise specified, the devices or working units used in this application can be obtained commercially or by conventional methods. Specifically, as follows:

[0115] Specifically, power supply groups 11 and 12 are connected to the main power supply bus via ordinary fuses 51 and 52, respectively. A fast disconnect switch 41, a smart fuse 61, and a fast disconnect switch 42 are installed on the main power supply bus between ordinary fuses 51 and 52.

The first load group 22 is connected between ordinary fuses 52 and 44 on the main power supply bus via a fast disconnect switch 44. The second load groups 31 and 32 are connected to the main power supply bus positions on both sides of the smart fuse 61 via ordinary fuses 53 and 54, respectively. The first load groups 21 and 22 are also connected via a backup fast disconnect switch 91. The charging port 71 is connected to the main power supply bus between the smart fuse 61 and the ordinary fuse 52. The control unit 81 controls the connection of fast disconnect switches 41 and 44, and the control unit 82 controls the connection of fast disconnect switches 42 and 43, as well as the backup fast disconnect switch 91.

[0124] The isolation device configuration module 310 is used to pre-group all loads according to preset rules to obtain at least two different types of load groups, and to configure different types of isolation devices for different types of load groups.

[0125] The isolation execution module 320 is used to perform different isolation processes based on the different types of isolation devices configured when a fault is detected in any load group.

[0127] See Figure 10 In some embodiments, the isolation device configuration module 310 includes a first isolation configuration module 311.

[0128] In some embodiments, the isolation execution module 320 includes a first isolation execution module 321 and a second isolation execution module 322. The first isolation execution module 321, upon detecting a fault in any first load group, controls a pre-configured fast disconnect switch to disconnect the faulty first load group from the power supply bus main line via a control unit. The second isolation execution module 322, upon detecting a fault in any second load group, disconnects the faulty second load group from the power supply bus main line via a pre-configured non-fast disconnect switch.

[0129] In some embodiments, the flying car power distribution system further includes at least two power supply units connected to the main power supply bus; the isolation device configuration module 310 further includes a second isolation configuration module 312. The second isolation configuration module 312 is used to pre-group all power supply units to obtain multiple power supply groups; wherein a non-fast isolation switch is configured for each power supply group, and a backup fast isolation switch is configured between any two power supply groups. The isolation execution module 320 further includes a third isolation execution module 323; the third isolation execution module 323 is used to disconnect the faulty power supply group from the main power supply bus through a pre-configured non-fast isolation switch when a fault is detected in any power supply group; and / or, control the fast isolation switches corresponding to the remaining power supply groups to be turned on through the control unit.

[0130] In some embodiments, the isolation device configuration module 310 further includes a third isolation configuration module 313; the third isolation configuration module 313 is configured to configure at least one backup fast disconnect switch between any two first load groups, and to configure at least two control units to control a preset number of fast disconnect switches and backup fast disconnect switches respectively. The isolation execution module 320 further includes a fourth isolation execution module 324; the fourth isolation execution module 324 is configured to, when a fault is detected in any control unit, control the corresponding preset number of fast disconnect switches and all backup fast disconnect switches to be turned on through the remaining control units.

[0131] In some embodiments, the flying car power distribution system also includes a charging port, and the isolation device configuration module 310 further includes: a fourth isolation configuration module 314; the fourth isolation configuration module 314 is used to pre-configure at least one fast isolation switch between the charging port and any power supply unit according to the access location of the charging port. The isolation execution module 320 further includes: a fifth isolation execution module 325; the fifth isolation execution module 325 is used to control the corresponding fast isolation switch to disconnect the charging port from all power supply units when the charging current of the charging port is detected to exceed a preset threshold.

[0132] In this implementation, the flying car power distribution system control device of this application divides the load in the power distribution system into multiple different types of load groups according to preset rules, and configures different types of isolation devices for different types of loads. When a fault such as a short circuit or open circuit exists in any load group, the faulty load group is accurately isolated by the pre-configured isolation devices to prevent the fault from spreading and to ensure the normal operation of the remaining load groups, so that the flying car can maintain normal operation, thereby significantly improving the overall safety performance of the flying car.
