[0049] The embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein.

[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 the same type of information from each other. For example, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0052] In the related art, the fault isolation accuracy of the power distribution system of the flying car is low, and it is easy to isolate the faulty operating units from the non-faulty operating units, which makes the flying car at risk of failing to operate normally, and thus easily affects the overall safety of the flying car.

[0053] In response to the above problems, an embodiment of the present application provides a flying car power distribution system control method, which can effectively ensure accurate isolation of faults, avoid fault propagation, and improve the overall safety performance of the flying car.

[0054] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0055] In the flying car power distribution system control method of the present application, the flying car power distribution system includes a power supply bus main line and multiple loads electrically connected to the power supply bus main line. Among them, the load may include a power unit. Among them, the power unit may refer to a working unit used to provide flying power for the flying car, such as a working unit composed of rotating blades and related drive devices. In addition, the load may also include other working units other than the power unit, which will not be described here. The power supply bus main line corresponds to the main power supply line of the distribution system, and the load is realized by connecting to the power supply bus main line.

[0056] Figure 1 It is a flow chart of a flying car power distribution system control method shown in an embodiment of the present application.

[0057] See also Figure 1 The flying car power distribution system control method of the present application includes:

[0058] S110, grouping all loads in advance according to preset rules to obtain at least two different types of load groups, and configuring 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 main line are grouped in advance according to preset rules, and different types of isolation devices are configured for different types of load groups according to the obtained different types of load groups.

[0060] The number of each type of load grouping may be at least one group.

[0061] S120, when a fault is detected in any load group, different isolation processes are performed according to different types of configured isolation devices.

[0062] In this step, when a fault is detected in any load group, different isolation processes are performed through the pre-configured isolation device. It should be understood that different types of isolation devices use different isolation processes. Among them, the isolation device of the present application can include at least two different types.

[0063] In this embodiment, the flying car power distribution system control method of the present 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 there is a short circuit or open circuit fault in any load group, the load group with the fault is accurately isolated by the pre-configured isolation device to avoid the spread of the fault and ensure the normal operation of the remaining load groups, so that the flying car maintains normal operation, thereby significantly improving the overall safety performance of the flying car.

[0064] Figure 2 It is another flow chart of the flying car power distribution system control method shown in the embodiment of the present application.

[0065] See also Figure 2 The flying car power distribution system control method of the present application includes:

[0066] S210, all loads are grouped in advance according to the rules necessary for maintaining the normal operation of the flying car, to obtain a first load grouping of a necessary type and a second load grouping of a non-necessary type; wherein the first load grouping is configured with a fast isolating switch, and the second load grouping is configured with a non-fast isolating switch.

[0067] In this step, all loads are grouped in advance according to the rules necessary for maintaining the normal operation of the flying car, and a first load group corresponding to a necessary type and a second load group corresponding to a non-necessary type are obtained. It should be understood that the necessary type may refer to the necessary type for maintaining the normal flight of the flying car, and the non-necessary type may refer to the non-necessary type for the normal flight of the flying car. Among them, a fast isolation switch is configured for the first load group to perform isolation processing on the first load group, and a non-fast isolation switch is configured for the second load group to perform isolation processing on the second load group.

[0068] Among them, the fast isolating switch can be a solid-state relay, a transistor, a field effect transistor or a composite form of the above components. The fast isolating switch can switch between on and off under the control of the control unit. The fast isolating switch has the advantages of fast cutting speed, low loss, light weight, high reliability and recoverability after cutting. Among them, the non-fast isolating switch can be one of the ordinary fuse and the smart fuse. The non-fast isolating switch has low cost and cannot be recovered after disconnection. Therefore, using a non-fast isolating switch to isolate non-essential types of loads can reduce the impact on the driving safety of the flying car.

[0069] The first load group and the second load group can be in a backup relationship. That is, when any first load group fails to work, another second load group can be converted into a first load group of a necessary type, thereby ensuring that the flying car can maintain normal flight. The number of first load groups is at least two, and the number of second load groups is at least one.

[0070] The load may be composed of a power propulsion unit and other load units. The power propulsion unit may refer to a working unit for providing flying power for the flying car, and other load units may refer to other working units in the power distribution system except the power propulsion unit, such as a detection unit, a power distribution unit, a voltage stabilizing unit, etc.

[0071] Furthermore, during the grouping process, the first load grouping may be composed of power propulsion units necessary to maintain the normal operation of the flying car, and the second load grouping may be composed of power propulsion units not necessary to maintain the normal operation of the flying car and other load units.

[0072] Furthermore, the load grouping can also be combined with the positional relationship of the loads, and specifically, the load grouping process can be combined with the positional symmetry relationship of the loads. The number of the first load grouping can be at least two groups, wherein each first load grouping can include two symmetrically distributed power propulsion units necessary for maintaining the normal operation of the flying car; the number of the second load grouping can be at least one group, wherein each second load grouping can include two symmetrically distributed power propulsion units not necessary for maintaining the normal operation of the flying car.

[0073] Furthermore, other load units can be distributed in different second load groups according to the relative backup relationship. It should be understood that any two other load units that back up each other can be located in different second load groups, so that after any second load group fails and is isolated, other load units in other second load groups that have a backup relationship can also maintain the normal operation of the corresponding functions.

[0074] As an example, a flying car has six power propulsion units (i.e., loads), among which, in order to ensure the continuous safe flight and landing of the flying car, at least four power propulsion units need to work continuously. When the above-mentioned recommended power units are grouped, 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, wherein each of the first load groups includes two symmetrically distributed power propulsion units, and similarly, the second load group also includes two symmetrically distributed power propulsion units.

[0075] As another example, taking the flying car in the aforementioned example, the flying car also includes three other load units, and there is a backup relationship between two of the three other load units. Then, one of the other load units in the backup relationship among the three other load units can form a second load group with two power propulsion units that are not necessary for maintaining the continuous safe flight and landing of the flying car, and 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 isolating switch to disconnect the first load group with the fault from the power supply bus main line; or when a fault is detected in any second load group, the pre-configured non-fast isolating switch is used to disconnect the second load group with the fault from the power supply bus main line.

[0077] In this step, after all load groups are grouped in advance, all load groups are continuously detected for faults. When any first load group is detected to have a fault or any second load group is detected to have a fault, the load group with the fault is isolated through the corresponding pre-configured isolation device; wherein, when it is determined that the first load group has a fault, the control unit controls the pre-configured fast isolating switch to disconnect the first load group with the fault from the power supply bus main line, and when the second load group has a fault, the pre-configured non-fast isolating switch is directly used to disconnect the second load group with the fault from the power supply bus main line. It should be understood that the non-fast isolating switch can generally be disconnected autonomously after the preset conditions are met (such as the instantaneous current increases to a preset value).

[0078] After any first load group has a fault and is isolated, a corresponding second load group can be automatically activated to replace the faulty 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 power propulsion units.

[0079] In the present application, the flying car power distribution system may also include: at least two power supply units connected to the power supply bus main line. It can be understood that the power supply unit may refer to a working unit in the flying car for providing power. Among them, the power supply unit may be a battery or other component that can provide electrical energy. When the power supply unit is working, the power supply unit is controlled by a relay to power on and off the entire high-voltage power distribution system, for example, powering on before the flying car flies and powering off when the flying car is not flying.

[0080] Figure 3 It is another flow chart of the flying car power distribution system control method shown in the embodiment of the present application.

[0081] See also Figure 3 After executing the above steps S210 and S220, the flying car power distribution system control method of the present application may further execute the following steps:

[0082] S230, pre-grouping all power supply units to obtain a plurality of power supply groups; wherein a non-fast isolating switch is configured for each power supply group, and a fast isolating switch is configured between any two power supply groups.

[0083] In this step, all power supply units are grouped in advance, wherein each power supply unit is grouped into an independent group, and a plurality of independent power supply groups are obtained. A non-fast isolating switch is configured for each power supply group to perform isolation processing on the power supply group. When the number of power supply groups is more than two, at least one fast isolating switch is configured between any two power supply groups to ensure the normal use of other power supply groups when any power supply group has a fault (such as a short circuit).

[0084] Each power supply group can be connected to the power supply main line through a non-fast isolating switch. It can be understood that each power supply group can be connected to the power supply main line through a non-fast isolating switch (such as a common fuse) at the output port. When a power supply group has a fault such as a short circuit, the power supply group with the fault can be isolated from the output port of the power supply group.

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

[0086] In this step, after all power supply groups are grouped in advance, all power supply groups are continuously tested for faults. When any power supply group is detected to have a fault, the corresponding non-fast isolating switch is used to disconnect the power supply group with the fault from the power supply bus main line, so as to isolate the power supply group with the fault. After the power supply group with the fault is isolated, the control unit controls the fast isolating switches corresponding to the remaining power supply groups to be turned on, so that the remaining power supply groups can be powered normally, ensuring the normal operation of the flying car.

[0087] It can be understood that when a short circuit occurs in a power supply unit in a power supply group, it is easy to cause an increase in the current in the power supply bus main line. When a fault is detected in any power supply group, the control unit will first control the fast isolating switches corresponding to the remaining power supply groups to disconnect, thereby achieving protection for other power supply groups.

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

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

[0090] Figure 4 It is another flow chart of the flying car power distribution system control method shown in the embodiment of the present application.

[0091] See also Figure 4 After executing the above steps S210 and S230, the flying car power distribution system control method of the present application may further perform the following steps:

[0092] S250, pre-configure at least one backup fast isolating switch between any two first load groups according to the grouping result, and configure at least two control units to respectively control a preset number of fast isolating switches and the backup fast isolating switch.

[0093] In this step, at least one backup fast isolating switch is configured between any two first load groups in advance according to all the grouping results in this application, and at least two control units are configured to respectively control a preset number of fast isolating switches and backup fast isolating switches. The backup fast isolating switch is mainly used for connecting the first load group to the power supply bus main line and performing normal operation by using other control units through the corresponding backup fast isolating switch after the control unit or fast isolating switch corresponding to the first load group fails, that is, when the first load group cannot be connected to the power supply bus main line through the corresponding fast isolating switch.

[0094] Among them, the number of fast isolating switches controlled by any two control units can be the same or different. Specifically, the number of fast isolating switches controlled by each control unit can be set by a pre-set association rule, for example, by evenly distributing or alternatingly distributing the fast isolating switches to all control units. Furthermore, the fast isolating switches corresponding to each first load grouping are controlled by an independent control unit. For example, if there are two groups of first load groups in the power distribution system, the fast isolating switches corresponding to each group of first load groups are controlled by an independent control unit. In this way, the impact on the normal operation of the flying car caused by a failure in any control unit can be avoided to the maximum extent, thereby ensuring the safety of the flying car.

[0095] The number of backup fast isolating switches controlled by any two control units may be the same or different. The same backup fast isolating switch may be controlled by an independent control unit or by two or more control units at the same time. For example, there is a backup fast isolating switch in the power distribution system, and the backup fast isolating switch may be controlled by two control units at the same time. When any control unit fails, the backup fast isolating switch may be turned on by the other control unit to ensure the normal operation of the first load group in the flying car.

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

[0097] In this step, after pre-configuring the control units, all control units are continuously detected. When any control unit fails, it means that the fast isolating switch it controls fails. Then, the corresponding fast isolating switches and all backup fast isolating switches are controlled by the remaining control units to ensure the normal operation of all first load groups.

[0098] Figure 5 It is another flow chart of the flying car power distribution system control method shown in the embodiment of the present application.

[0099] See also Figure 5 In the flying car power distribution system of the present application, the flying car power distribution system may further include a charging port. It should be understood that the charging port may be connected to any position of the power supply bus main line or to a branch formed by connecting the first load groups.

[0100] After executing the above steps S210 and S230, the flying car power distribution system control method of the present application may further execute the following steps:

[0101] S270, pre-configure at least one fast isolating switch between the charging port and any power supply unit according to the access position of the charging port.

[0102] In this step, at least one fast isolating switch is pre-configured between the charging port and any power supply unit according to the access position of the charging port in the power distribution system.

[0103] Among them, 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. That is, at least one fast isolating switch is provided between the charging port and any power supply unit.

[0104] S280: When it is detected that the charging current of the charging port exceeds a preset threshold, the control unit controls the corresponding fast isolating switch to disconnect the charging port from all power supply units.

[0105] In this step, when a fault occurs in the charging port, that is, when a surge in charging current is detected and exceeds a preset threshold, the control unit controls the corresponding fast isolating switch to disconnect the charging port from all power supply units, thereby avoiding damage to the power supply units. After the charging port returns to normal, the corresponding fast isolating switch can be turned on again to restore the connection between the charging port and all power supply units, thereby restoring the charging function of all power supply units.

[0106] Among them, at least one fast isolating switch or at least one non-fast isolating switch can also be configured between the charging port and the first load group and the second load group. In this way, when a fault occurs in the charging port, the connection between the charging port and the first load group and the second load group can be disconnected through the corresponding fast isolating switch or non-fast isolating switch.

[0107] Figure 6 It is another flow chart of the flying car power distribution system control method shown in the embodiment of the present application.

[0108] See also Figure 6 In the present application, the aforementioned steps S210, S230, and S270 can be performed simultaneously, and then the aforementioned step S250 is performed, and then the aforementioned steps S220, S240, S260, and S280 are performed simultaneously. That is to say, the flying car power distribution system control method of the present application can first pre-group the loads and power supply units in the power distribution system, and then configure the corresponding isolation devices according to the grouping results, and then continuously detect faults. After detecting that the corresponding group has a fault, the pre-configured isolation device (i.e., a fast isolation switch or a non-fast isolation switch) is used to implement isolation processing for the group with the fault.

[0109] It should be noted that in the present application, the same fast isolating switch or non-fast isolating switch can be used to perform isolation processing for different groups with faults at the same time. That is, different isolation devices are configured according to different groups. In different isolation processing steps such as steps S220, S240, S260, and S280, the same type of isolation device used to perform isolation processing can be the same fast isolating switch or non-fast isolating switch. In addition, in the present application, there may be only a single fault, that is, there is only a single fault in all load groups, power supply groups, control units, and charging ports.

[0110] In this embodiment, the control method of the power distribution system of the flying car of the present application is to pre-group the loads in the flying car into the first and second load groups according to whether they are necessary to maintain normal operation, and respectively configure fast and non-fast isolating switches. When the first load group fault is detected, the control unit controls the fast isolating switch to disconnect it from the power supply bus main line; when the second load group fault is detected, the non-fast isolating switch is disconnected. Through the above control method, the fault isolation pertinence and efficiency can be effectively improved, thereby optimizing the stability and reliability of the power distribution system, and because the number of fast isolating switches configured is effectively reduced, the overall cost and complexity of the power distribution system can also be reduced; the control method of the power distribution system of the flying car of the present application is also configured in advance according to the grouping results. At least two control units are configured to control the preset number of fast isolating switches and backup fast isolating switches respectively, so as to realize the redundant design of the control unit, and when any control unit is detected to have a fault, the remaining control units can control the corresponding preset number of fast isolating switches and all backup fast isolating switches to be turned on, effectively avoiding the failure of the fast isolating switch to work normally due to the failure of a single control unit, thereby ensuring the safety performance of the flying car.
