[0063] Embodiment 1

[0064] Reference Figures 1-3 For an embodiment of the present application, a transportation vehicle fault management method is provided, as shown in Figure 1 comprises:

[0065] S1: dividing the hydrogen fuel cell transportation vehicle into a fuel cell system part and a power battery system part;

[0066] S2: In the hybrid mode, the vehicle controller receives and detects the fault information of the whole machine and each component in real time, handles it through the fault handling control process, and ensures the safety of the whole machine, components and transported objects.

[0067] Further, as shown in Figure 2 The power system architecture diagram of the hydrogen fuel cell transport vehicle is shown. The power system of the hydrogen fuel cell transport vehicle includes a hydrogen system and its hydrogen supply pipeline, a fuel cell system, a high-voltage bus, a power battery system, and an electric drive system. In the hydrogen fuel cell system, it is mainly composed of a stack, a system switch, a DCDC boost circuit, and a high-voltage relay at the back end. In the power battery system, it is mainly composed of a high-voltage relay and a power battery module.

[0068] Further, the hydrogen fuel cell transport vehicle power system can control the opening and closing of the fuel cell system high-voltage relay and the power battery system relay, as well as the power transmission of the system, so as to realize the multiple power driving modes of the hydrogen fuel cell transport vehicle, including single hydrogen fuel cell system driving, single power battery system driving, and hybrid power system driving.

[0069] Further, for the hydrogen fuel cell transport vehicle power system architecture, when the whole machine or component fails, the following fault management method is designed to reasonably handle it to ensure the safety of the whole machine, components and transported objects. The hydrogen fuel cell transport vehicle power system fault management method is shown in Figure 3 .

[0070] Further, the fault handling control process includes five fault levels. Level 0 is no fault of the part, level 1 is slight fault of the part, level 2 is whole vehicle power limiting fault, level 3 is whole vehicle stop fault, and level 4 is whole vehicle emergency power-off fault. The severity of the fault increases from level 0 to level 4.

[0071] Further, the hydrogen fuel cell transport vehicle power system fault management method includes the following steps:

[0072] Step 1: In the hybrid mode, the vehicle controller (VCU) receives and detects the fault information of the whole machine and each component in real time:

[0073] If the whole machine or component has a serious fault (level 4 fault), the VCU sends the fuel cell system shutdown and disconnects the fuel cell high-voltage relay instruction to the fuel cell system, and sends the hydrogen system bottle valve closing instruction to the hydrogen system, respectively cutting off the energy supply circuit of the hydrogen system and the fuel cell system and entering step 2;

[0074] If the whole machine or component does not have a serious fault (level 4 fault), step 5 is entered;

[0075] Step two: VCU continuously receives the high-voltage relay state signal sent by the fuel cell system. If the fuel cell high-voltage relay has been disconnected or the operation has timed out, the VCU enters step three;

[0076] Step three: After ending step one and step two, the VCU sends a command to disconnect the high-voltage relay of the power battery system to the power battery system and sends a command to actively discharge to the electric drive system, so that the high-voltage loop of the power battery is cut off and the remaining energy is discharged. At this time, since the high-voltage relay of the fuel cell system has been disconnected one step earlier, the active discharge action of the fuel cell system and the whole machine is isolated, and the failure of the fuel cell to respond to the emergency stop and active discharge in time will not cause risks to the active discharge of the whole machine.

[0077] Step four: VCU continuously receives the high-voltage relay state signal sent by the power battery system. If the power battery high-voltage relay has been disconnected or the operation has timed out, the VCU prohibits any high-voltage electrical work and lowers the high voltage;

[0078] Step five: The vehicle controller (VCU) receives real-time fault information of the hydrogen system and the fuel cell system. If a level 3 fault occurs, the VCU sends a fuel cell system shutdown command to the fuel cell system and a hydrogen system bottle valve closing command to the hydrogen system, only cutting off the energy supply loop of the hydrogen system, and the whole machine can still run in a separate power battery power mode; if neither the hydrogen system nor the fuel cell system has a level 3 fault, step eight is entered;

[0079] Step six: In the separate power battery power mode, the VCU collects the SOC value of the power battery system in real time and compares it with the first threshold value: when the power battery SOC is greater than or equal to the first threshold value, the whole machine is allowed to run at full power of the power battery, otherwise step seven is entered;

[0080] Step seven: The VCU collects the SOC value of the power battery system in real time and compares it with the second threshold value: when the power battery SOC is greater than or equal to the second threshold value, the whole machine runs at a limited power of the power battery and sends a fault prompt message to the vehicle instrument, otherwise the whole machine executes at zero torque;

[0081] Step eight: The vehicle controller (VCU) receives real-time fault information of the hydrogen system and the fuel cell system. If a level 2 fault occurs, the whole machine runs at a limited power of the fuel cell system and sends a fault prompt message to the vehicle instrument, otherwise step nine is entered;

[0082] Step nine: The vehicle controller (VCU) receives real-time fault information of the hydrogen system and the fuel cell system. If a level 1 fault occurs, the whole machine only sends a fault prompt message and runs at full power in a hybrid power mode, otherwise it directly runs at full power in a hybrid power mode.

[0083] The embodiment also provides a transport vehicle fault management system, comprising:

[0084] The division module divides the hydrogen fuel cell transport vehicle into a fuel cell system part and a power battery system part.

[0085] The disposal module, when the whole machine is in the hybrid mode, receives and detects the fault information of the whole machine and each component in real time, and disposes through a fault processing control flow, so as to ensure the safety of the whole machine, the components and the transported objects.

[0086] Further, the system further comprises:

[0087] The memory is configured to store the program.

[0088] The processor is configured to load the program to execute the transport vehicle fault management method.

[0089] The embodiment also provides a computer readable storage medium storing a program, and the program is executed by a processor to implement the transport vehicle fault management method.

[0090] The storage medium provided by the embodiment belongs to the same inventive concept as the transport vehicle fault management method provided by the above embodiment, and the technical details not described in detail in the embodiment can be referred to the above embodiment, and the embodiment has the same beneficial effects as the above embodiment.

[0091] Through the above description of the embodiments, those skilled in the art can clearly understand that the present application can be realized by software and necessary general hardware, and of course can be realized by hardware, but in many cases the former is a better embodiment. Based on this understanding, the technical solutions of the present application or the part that contributes to the prior art can be embodied in the form of a software product, which can be stored in a computer readable storage medium, such as a floppy disk, a read-only memory (ROM), a random access memory (RAM), a FLASH, a hard disk or an optical disk, etc., including a plurality of instructions to make a computer device (which can be a personal computer, a server, or a network device, etc.) execute the method of each embodiment of the present application.

[0092] Embodiment 2

[0093] The following is another embodiment of the present application, which provides a transport vehicle fault management method. In order to verify the beneficial effects of the present application, the specific embodiment and the implementation effect are scientifically demonstrated.

[0094] The embodiment is as follows:

[0095] The present application is applied on a company vehicle, and the hydrogen fuel cell transport vehicle can run in multiple power driving modes of single hydrogen fuel cell system driving, single power battery system driving and hybrid power system driving respectively.

[0096] When a 3-level fault occurs in the hydrogen system or the fuel cell system, the whole machine runs in the single power battery system power mode, runs at full power when the SOC is higher than 50%, runs at limited power of 50% when the power battery SOC is between 30% and 50%, and the whole machine is zero-torque limited when the SOC is lower than 30%, i.e. the whole machine is parked.

[0097] The present application reasonably classifies and manages the faults of the power system of the hydrogen fuel cell transport vehicle, and when a 4-level fault occurs in the whole machine power system, the power system can be quickly cut off, thereby ensuring the safety of the transported objects, the whole machine and the parts; when a 3-level fault occurs in the hydrogen system or the fuel cell system, the whole machine can still run in the single power battery system power mode, so that the transported objects can slowly drive the vehicle to a safe place or a repair point, thereby ensuring the safety of the transported objects or timely repairing the vehicle. The fault management method provided by the present application can provide a good vehicle experience for users.

[0098] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
