Detailed ways

The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

Fig. 1 is a flowchart of a hydrogenation control method for a hydrogen fuel cell vehicle provided by an exemplary embodiment. As shown in Figure 1, the method may include the following steps:

In step S11, if the hydrogenation instruction triggered by the user is received, the vehicle control unit (VCU) sends a hydrogenation request to the hydrogen storage controller.

In step S12, if the hydrogenation request is received, the hydrogen storage controller determines whether the hydrogen management system (Hydrogen Management System, HMS) meets the hydrogenation conditions.

In step S13, if it is determined that the HMS has hydrogenation conditions, the hydrogen storage controller or the VCU sends a cover opening request to the body control module (BCM).

In step S14, if the lid opening request is received, the BCM controls the hydrogenation port lid to open.

In step S15, if it is determined that the HMS has hydrogenation conditions, the hydrogen storage controller controls the HMS to perform hydrogenation.

When refueling a hydrogen fuel cell vehicle, the user can press a physical button dedicated to hydrogen refueling to send a hydrogen refueling instruction. When the VCU receives the hydrogenation instruction, it can send a hydrogenation request to the hydrogen storage controller.

At this time, if while sending a hydrogenation request to the hydrogen storage controller, the VCU also sends a lid opening request to the BCM so that the BCM will open the hydrogenation port cover, and the hydrogen storage controller cannot jump to the hydrogenation state so that In the case that the vehicle cannot be hydrogenated, the hydrogenation port cover will still be opened. Even if the instrument can prompt the driver "the hydrogen refueling system is faulty, please close the hydrogen refueling port cover", the driver is still required to manually close the hydrogen refueling port cover, which is complicated for the customer to operate. In addition, for safety reasons, it is also necessary to output a message prompting the user to close the hydrogenation port cover, for example: "The hydrogenation system is faulty, please close the hydrogenation port cover". More importantly, because the hydrogenation port cover is opened but not hydrogenated, there may be hydrogen leakage. If the hydrogenation port cover is not closed in time, it may cause the hydrogenation port to continuously leak hydrogen. The strategy has unavoidable security risks.

This solution solves the above technical problems. Specifically, when the VCU sends a hydrogenation request to the hydrogen storage controller, it does not send a lid opening request to the BCM at the same time. Instead, after the hydrogen storage controller determines that the HMS has the hydrogenation conditions, the hydrogen storage controller or VCU sends a lid opening request to the BCM.

The hydrogen storage controller is the core control component in the HMS, which is used to control other components in the HMS to realize the hydrogenation function. Whether the HMS has the hydrogenation conditions can be judged by detecting one or more of the hydrogen concentration in the vehicle, the hydrogen concentration in the hydrogen tank of the HMS, temperature, pressure, and whether the hydrogen fuel cell is abnormal. For example, when the hydrogen concentration in the vehicle is less than a predetermined concentration threshold, it means that there is no hydrogen leakage. The judgment condition can also be determined according to related technologies, and will not be described in detail here.

In another embodiment, based on FIG. 1, if it is determined that the HMS has hydrogenation conditions, the hydrogen storage controller or the VCU sends a lid opening request to the BCM (step S13) may include:

If it is determined that the HMS has the hydrogenation conditions, the hydrogen storage controller sends a confirmation message to the VCU; if the confirmation message is received, the VCU sends a lid opening request to the BCM.

In this embodiment, the VCU sends a lid opening request to the BCM, and the VCU controls both the BCM and the hydrogen storage controller. Therefore, the control strategy is concentrated in the VCU, and the hydrogen storage controller does not need to communicate with the BCM, thus saving hydrogen storage. The communication line between the controller and the BCM.

In another embodiment, on the basis of FIG. 1, if it is determined that the HMS is capable of hydrogenation, the step of the hydrogen storage controller or VCU sending a cap opening request to the BCM (step S13) may include: if it is determined that the HMS is capable of hydrogenation If conditions are met, the hydrogen storage controller directly sends a lid opening request to the BCM.

In this embodiment, after determining that the HMS has hydrogenation conditions, the hydrogen storage controller directly sends a lid opening request to the BCM, and the VCU only needs to communicate with the BCM. Therefore, the control strategy in the VCU is relatively simple, which reduces the risk of errors. Both the VCU and the hydrogen storage controller jointly control the hydrogenation process, which can reduce the risk of hydrogen leakage when the hydrogenation port cover is opened under abnormal conditions.

In another embodiment, based on FIG. 1, if a hydrogenation instruction triggered by a user is received, the step of sending a hydrogenation request by the vehicle controller VCU to the hydrogen storage controller (step S11) may include:

If the hydrogenation instruction triggered by the user is received, the VCU determines whether the state of the vehicle's power system allows hydrogenation; if it is determined that the state of the vehicle's power system allows hydrogenation, the VCU sends a hydrogenation request to the hydrogen storage controller.

Among them, according to the state of the power system (including each device), it can be judged whether the power system of the vehicle is ready for hydrogen refueling. The state of the power system allows hydrogenation as a necessary condition for the VCU to send a hydrogenation request to the hydrogen storage controller. In this way, when the vehicle's power system is ready for hydrogenation, the hydrogenation request is sent to the hydrogen storage controller to avoid the start of the subsequent hydrogenation control process when the vehicle is not suitable for hydrogenation. Trouble or avoid unnecessary actions.

Specifically, the above-mentioned VCU judging whether the state of the vehicle's power system allows hydrogen refueling may include: if the vehicle is stationary, the current gear is in P gear, the power mode of the vehicle is in the non-power-on mode, and the predetermined multiple control devices in the power system are In the standby state, the VCU determines that the state of the vehicle's power system allows hydrogen refueling.

Among them, if the vehicle speed is less than a predetermined threshold (for example, 2km/h), the vehicle can be considered to be stationary; if the current gear is in the P gear, it can be considered that the vehicle can perform hydrogen refueling operations in the parking state; no power-on mode It may include the power supply in the OFF, ACC, and IG positions. For example, the non-power-on mode may be the position where the power supply is ON; the predetermined multiple control devices in the power system may include, for example, a starter motor, a drive motor, a DCDC module, and a battery management system. Any number of ones. If these control devices are in the standby state, it can be further determined that the state of the power system allows hydrogenation.

In this embodiment, by detecting the states of multiple vehicle components, it is possible to identify whether the state of the power system allows hydrogen refueling. The method is simple and easy to operate.

In another embodiment, based on FIG. 1, the method may further include: if it is determined that the HMS does not meet the hydrogenation conditions, the hydrogen storage controller sends a prompt instruction to the output device to cause the output device to output a fault prompt message.

Among them, the output device may be a meter or a display screen of the vehicle. For example, a message box can be displayed on the display screen: "The hydrogenation system is faulty, the vehicle cannot be hydrogenated" or "The hydrogenation system is faulty, please go to the 4S shop for repair". In this embodiment, if it is determined that the HMS does not have the hydrogenation conditions, a prompt message is output so that the user can understand the fault situation in time, so as to take corresponding measures in time to reduce the damage of the fault.
