[0036] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0037] In order to solve the problem that there is still a lack of a more comprehensive method for dealing with fuel cell vehicle fuel and power anomalies, an embodiment of the present invention provides a fuel cell vehicle fuel and power anomaly processing method, such as Figure 1 As shown, the method includes:

[0038] S101, obtaining operating condition data of a fuel cell system of a target vehicle;

[0039] The above step S101 further includes S1011:

[0040] S1011. Acquire operating condition data of a fuel cell system of a target vehicle based on vehicle sensors; when the operating condition data indicates that the fuel cell system of the target vehicle is abnormal, feedback the abnormality of the fuel cell system to a VCU; and perform alarm operations and risk avoidance operations based on the VCU.

[0041] For example, when the fuel cell vehicle is working, the vehicle sensors normally receive operating condition data from the vehicle and the fuel-electric system. When an abnormality occurs in the fuel-electric system, the vehicle sensors receive abnormal signals from the fuel-electric system and report them to the VCU, which is used to control the execution of alarm operations and risk avoidance operations.

[0042] Specifically, the present application can reasonably install hydrogen leakage sensors at locations where hydrogen leakage may occur. It is recommended to install no less than 4 sensors at the hydrogen filling port, hydrogen storage system, and fuel cell installation location, and they should be installed at locations where hydrogen is most likely to accumulate, generally at the highest local point and in places with poor ventilation. At the same time, a temperature test recorder is used to monitor the temperature of the fuel cell and its related components, and a voltage and current sensor is used to detect the voltage and current.

[0043] Exemplarily, the architecture of the embodiments of the present application includes a fuel cell system, a fuel cell stack, a solenoid valve, a drive motor, a power battery, a braking device, a VCU (Voltage Control Unit), a FCCU (Fuel Cell Control Unit), a sensor, an air compressor, a hydraulic lift rod, a buzzer, a warning light, and the like.

[0044] The above-mentioned VCU is an indispensable electronic control system for new energy vehicles, and it is also the control center of pure electric vehicles. Its core responsibilities cover the collection of vehicle information, the interpretation of driver intentions, the control of vehicle operation, and the diagnosis and handling of faults. It can fully receive signals from various key components such as the motor automatic control system, accelerator pedal, brake pedal, and conduct in-depth analysis and precise response based on the driver's driving intentions. It is responsible for supervising the attitude layer of the control panel of the next-level components, and plays a leading role in the feedback of the rechargeable battery heating brake system, network security management, fault detection and repair, and real-time monitoring of vehicle conditions.

[0045] The FCCU provides a hardware channel to collect faults and put the device into a safe state when a fault is detected in the device. No CPU intervention is required for the collection and control operations, providing a systematic fault collection and control method.

[0046] S102: When the operating condition data feedback indicates that the fuel cell system of the target vehicle is abnormal, executing an alarm operation and a risk avoidance operation.

[0047] The above step S102 further includes S1021:

[0048] S1021. The alarm operation includes an internal alarm operation and an external alarm operation. The method further includes: when the operating condition data feedback indicates that the fuel cell system of the target vehicle is abnormal, performing an internal alarm operation and an external alarm operation, wherein the internal alarm operation includes a display screen alarm and a voice alarm, and the external alarm operation includes a warning light alarm and a buzzer alarm.

[0049] For example, when the operating condition data feedback indicates that the fuel cell system of the target vehicle is abnormal, the vehicle display screen displays the fuel-electric system abnormality and gives voice feedback to the driver, and performs internal alarm operations in a timely manner through both sound and light channels; then the VCU first sends instructions to the buzzer and warning light, requiring the buzzer to beep at 80dB and the warning light to flash to alert nearby pedestrians, so as to realize external alarm operations. When the vehicle has an abnormality, the buzzer and warning light can be used to warn surrounding vehicles and pedestrians to avoid possible accidents.

[0050] Based on the setting of the above scheme, the automatic alarm and warning function can trigger the buzzer with a high decibel when an abnormality occurs, and make the warning light flash at a high frequency, so that the surrounding cars and pedestrians can avoid the abnormal fuel cell vehicle in time to avoid danger.

[0051] S1022, control the fuel cell system to execute a fuel-electric shutdown command to stop providing power to the drive motor; and control the power battery system to execute a deceleration shutdown command to control the drive motor to brake. The fuel-electric shutdown command and the deceleration shutdown command are received from the VCU via the FCCU.

[0052] For example, the present application considers that the fuel-electric system should not continue to provide power due to a fault at this time, controls the VCU to send a fuel-electric shutdown command to the FCCU, and the fuel-electric system receives and executes the shutdown command, and at the same time issues a vehicle deceleration command to the power battery system, so as to ensure that the fuel-electric system does not cause further danger due to the fault problem when power is stopped and the drive motor is braked. Through the integrated shutdown and deceleration setting, after the fuel cell system shuts down due to a fault, the vehicle no longer continues to run, but uses the power battery to decelerate the vehicle until it stops, ensuring the safety of the vehicle driver and passengers.

[0053] Specifically, the power battery system adjusts the power output of the drive motor, assists the drive motor in controlling the brake equipment, and decelerates the vehicle. When the fuel-electric system is abnormal, it can ensure that the fuel-electric system is shut down and no longer outputs power to the drive motor, ensuring that the fuel-electric system and the battery stack are not further damaged, and that the safety of the driver and passengers is not affected due to faulty operation.

[0054] Based on the above scheme, the drive motor can adjust the power of the whole vehicle by identifying the abnormality of the fuel-electric system and receiving the instructions sent by the VCU, so as to slow down the vehicle until it stops, ensuring that the vehicle will not get out of control and affect the safety of the driver and passengers and traffic safety.

[0055] It should be noted that this application is also scalable, that is, the VCU can add an automatic rescue call module according to needs, and after installing a visual recognition system, it can realize automatic parking recognition, helping drivers avoid making wrong operations in critical situations.

[0056] S1023, controlling the air compressor to purge the hydrogen inside the fuel cell system.

[0057] It is understandable that the raw fuels such as natural gas, oil, methanol, etc., as reactants, enter the battery body after hydrogen is separated by the "fuel reforming device", and the oxygen in the air at the other end enters the battery body and supplies the battery electrodes respectively, and the hydrogen and oxygen undergo electrochemical reactions through the electrolyte to generate a potential difference, thereby forming a low-voltage direct current output. As the "heart" of hydrogen fuel cell vehicles, the fuel cell system bears the heavy responsibility of energy conversion and power drive. It not only needs to efficiently convert hydrogen into electrical energy, but also ensure stable operation under various working conditions, especially its electronic control system. For hydrogen fuel cell vehicles, it is like the human nervous system, responsible for the control and overall regulation of various components of the power system, and obtains key parameters such as air pressure, hydrogen pressure, temperature, humidity, etc. through various sensors to ensure that the hydrogen flow and pressure remain within a safe range. Any small leak may cause a serious safety accident.

[0058] Exemplarily, the present application simultaneously controls the air compressor to purge the residual hydrogen inside the fuel-electric system to ensure that there is no residual hydrogen in the system to ensure safety. When the fuel-electric system is shut down and stops providing power to the drive motor, the residual hydrogen is also purged at the same time.

[0059] Based on the above scheme, it can ensure that the residual hydrogen can be purged smoothly when the fuel cell system is shut down, ensuring that there is no residual hydrogen in the system, and facilitating subsequent inspections while ensuring safety.

[0060] S1024, controlling the engine compartment solenoid valve to drive the hydraulic mechanical rod to rise to open the vehicle engine compartment cover.

[0061] For example, after the vehicle completes deceleration braking and the fuel-electric system completes residual hydrogen purging, the VCU sends a control command to the front engine compartment solenoid valve, which is powered by the power battery to drive the hydraulic mechanical rod to rise and automatically open the front engine compartment cover, providing convenience for subsequent fuel cell system maintenance and ensuring the safety of the driver and passengers.

[0062] Based on the above scheme, the solenoid valve can be adjusted to prop up the hydraulic mechanical rod, thereby opening the engine cover, realizing the shutdown and purging of the fuel-electric system, and automatically opening the engine cover after the whole vehicle slows down and stops, which is convenient for driver and passenger safety and subsequent maintenance.

[0063] The above scheme is set up to complete the shutdown and purging of the fuel cell system in the vehicle; after the vehicle completes deceleration and parking, the front engine cover is automatically opened. On the one hand, it improves safety and prevents the accumulation of purging hydrogen. On the other hand, it helps to prevent the driver from making incorrect operations due to nervousness when encountering emergencies, and it also facilitates subsequent engineers to carry out fuel-electric system maintenance.

[0064] Through the above technical scheme, the fuel cell vehicle fuel-electric abnormality processing method provided by the present invention is to solve the problem that there is still a lack of a more comprehensive response method for fuel cell vehicle fuel-electric abnormality. The present invention uses the fuel cell system monitoring and protection function, and the fuel-electric system sensor monitors the abnormal data signal of the fuel cell system. When an abnormal signal occurs, it automatically sends the fault condition to the VCU, and the feedback causes the fuel-electric system to shut down, the system to be purged, the whole vehicle to slow down and stop, and the front engine cover to open automatically. In the above scheme, a self-protection control method for fuel cell vehicle fuel-electric system abnormality is proposed to maintain the safety of drivers and passengers, ensure that when a vehicle failure occurs, the fuel-electric system can automatically shut down, the engine cover will automatically pop up, the buzzer and warning light will remind surrounding cars and pedestrians to avoid it, the remaining hydrogen will be purged to prevent accidents caused by high temperature, and the heat will be quickly dissipated, which is convenient for further maintenance of the fuel-electric system.

[0065] Furthermore, as a response to the above Figure 1 In order to realize the method shown in the figure, the embodiment of the present invention also provides a fuel cell vehicle fuel and power abnormality processing device for Figure 1 The device embodiment corresponds to the aforementioned method embodiment. For ease of reading, this device embodiment will not repeat the details of the aforementioned method embodiment one by one, but it should be clear that the device in this embodiment can correspond to all the contents of the aforementioned method embodiment.

[0067] The operating unit 22 is used to perform warning operations and risk avoidance operations when the operating condition data feedback indicates that the fuel cell system of the target vehicle is abnormal.

[0068] The processor includes a kernel, and the kernel calls the corresponding program unit from the memory. One or more kernels can be set, and a fuel cell vehicle fuel and power abnormality processing method is implemented by adjusting kernel parameters, which can solve the problem that there is still a lack of a more comprehensive response method for fuel cell vehicle fuel and power abnormality.
