[0002] As fuel cell vehicles gradually come into the public eye and receive widespread attention, it is inevitable that they will be widely adopted by households. Drivers typically determine whether the vehicle has started by checking if the start indicator light is on, thus confirming whether the vehicle can be driven normally.

[0003] In the prior art, when the hybrid control unit (HCU) in a fuel cell vehicle illuminates the vehicle start indicator light, the vehicle may fail to start normally, which could mislead the driver. Summary of the Invention

[0017] If the detected value of the power battery is greater than the second preset value, the FCU is controlled to start the purging function, and the power battery is controlled to supply power to the fuel cell;

[0018] When the purging function is detected to be complete and the vehicle is started via the fuel cell, the vehicle start indicator light is controlled to display.

[0019] Optionally, after the step of sending a request to the fuel cell controller (FCU) to obtain the fuel cell status when the power battery charge value is detected to be less than or equal to the first preset value, so that the FCU can determine the fuel cell status based on the stack parameters, the method further includes:

[0020] Receive the second fuel cell status returned by the FCU;

[0021] If the second fuel cell state is found to meet the preset conditions, it is determined whether the power battery charge value is greater than a third preset value.

[0022] If the power battery's charge level is detected to be greater than a third preset value, the power battery is controlled to supply power to the fuel cell.

[0023] If the vehicle is detected to be started by the fuel cell, the vehicle start indicator light is controlled to be displayed.

[0024] Optionally, detecting whether the power system has a fault includes:

[0025] Send a power-on command to the power system of the target vehicle so that the power system performs a power-on operation according to the power-on command, and send the status parameters of each component in the power system to the HCU;

[0026] Determine whether there is any abnormal parameter information based on the status parameters returned by the power system;

[0027] The abnormal parameter information is used to detect whether the power system is faulty.

[0028] Optionally, after the step of sending a request to the fuel cell controller (FCU) to obtain the fuel cell status when the power battery charge value is detected to be less than or equal to the first preset value, so that the FCU can determine the fuel cell status based on the stack parameters, the method further includes:

[0029] If the power battery charge value is detected to be less than a target threshold, a warning command is sent to the vehicle dashboard to cause the vehicle dashboard to display a warning message, wherein the target threshold includes a second preset value or a third preset value.

[0030] According to a second aspect of the embodiments of this application, a vehicle indicator light display device is provided, the device comprising:

[0031] The detection module is used to detect whether there is a fault in the power system when the vehicle is powered on.

[0032] The sending module is used to send a request to the battery management system (BMS) to close the relay when the normal operation of the power system is detected, so that the BMS closes the relay.

[0033] The acquisition module is used to acquire the power battery's charge level.

[0034] The determination module is used to determine the status of the vehicle start indicator light based on the relationship between the power battery charge value and a first preset value, wherein the vehicle start indicator light is used to indicate whether the fuel cell vehicle is in a startable state.

[0035] According to a third aspect of the embodiments of this application, an electronic device is provided, comprising:

[0036] processor;

[0037] Memory used to store the processor's executable instructions;

[0038] The processor is configured to execute the instructions to implement the vehicle indicator light display method as described in the first aspect.

[0039] According to a fourth aspect of the embodiments of this application, a computer-readable storage medium is provided, which, when the instructions in the storage medium are executed by a processor of a mobile terminal, enables the mobile terminal to perform the vehicle indicator light display method as described in the first aspect of this application.

[0040] According to a fifth aspect of the embodiments of this application, a vehicle is provided, including the electronic equipment described in the third aspect of this application.

[0041] The technical solutions provided by the embodiments of this application may include the following beneficial effects:

[0042] This application detects a fault in the power system upon receiving a vehicle power-on signal. If the power system is detected to be operating normally, a request to close a relay is sent to the Battery Management System (BMS) to close the relay. The battery charge level is then acquired. The status of the vehicle start indicator light is determined based on the relationship between the battery charge level and a first preset value. The vehicle start indicator light indicates whether the fuel cell vehicle is ready to start. Specifically, during vehicle power-on, the HCU detects a fault in the vehicle's power system. If the power system is operating normally, the BMS is controlled to close a relay. Given that the power system is fault-free and the relay is closed, the battery charge level is assessed to determine if it is sufficient to start the vehicle. The relationship between the battery charge level and a preset value is then used to determine whether to illuminate the vehicle start indicator light. When the HCU illuminates the start indicator light, it indicates that the vehicle is ready to start and drive. This solves the problem in existing technologies where relying solely on power system fault detection and relay closure results in indicator light display that fails to meet regulatory requirements, leading to vehicle inability to start. This application determines whether the vehicle starts normally by obtaining the power battery charge value based on whether the power system is faulty and whether the relay is closed. In other words, by setting the rules for the vehicle start indicator light display, it reduces the misleading effect on the driver caused by the vehicle start indicator light displaying incorrectly due to insufficient power battery charge, thereby improving the user driving experience.

[0043] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0052] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0053] It should be noted that the embodiments of this application are applied to fuel cell vehicles. Fuel cell vehicles have two drive units (power battery and fuel cell). As long as one drive unit is working properly, the vehicle can drive normally. Currently, after the HCU determines that there are no faults in the power system-related components, it first requests the power battery to close the relay. If the power battery relay is closed, the Ready light will be lit (lighting the Ready light means that the vehicle can drive normally). If the power battery charge is too low to support the vehicle's pure electric start-up, it will then determine whether the current charge can support the fuel cell to start. If the fuel cell cannot start, the Ready light will be turned off. This does not comply with the regulatory requirement that the Ready light should be lit to indicate that the vehicle can drive normally.

[0054] The first embodiment of this application relates to a vehicle indicator light display method, see [link to relevant documentation]. Figure 1 , Figure 1 This is a flowchart of a vehicle indicator light display method provided in an embodiment of this application, including the following steps:

[0055] Step 101: Upon receiving a vehicle power-on signal, check for any faults in the powertrain system.

[0056] It should be noted that in this embodiment, when the driver performs the vehicle power-on operation, specifically, the driver can power on the vehicle by turning the ignition key to the ON or START position. At this time, by pressing a button, such as one-button start, the KBCM (Electronic Region Control System Body, integrated with the Body Electronic Domain Control Unit PEPS and BCM) will send a KL15 ON signal to wake up the vehicle. The HCU will send a POWERUP signal to the relevant power system components. It should be noted that KL15 is a standard automotive contact in the German Institute for Standardization standard document DIN 72552, which represents the engine ignition signal and the signal to start the vehicle. In this embodiment, it is the vehicle power-on signal. After receiving the vehicle power-on signal, the HCU will detect whether there is a fault in the power system.

[0057] Specifically, detecting whether the powertrain system is faulty includes: sending a power-on command to the powertrain system of the target vehicle so that the powertrain system performs a power-on operation according to the power-on command; sending the status parameters corresponding to each component in the powertrain system to the HCU; determining whether there is abnormal parameter information based on the status parameters returned by the powertrain system; and detecting whether the powertrain system is faulty based on the abnormal parameter information.

[0058] It should be noted that in this embodiment, when the HCU receives the KL15 ON signal, it will send a POWERUP signal, that is, send a power-on command to the relevant power system components. The relevant power system components include the motor controller, the power battery controller, the high-low voltage converter, and the fuel cell controller. After receiving the power-on command, each relevant component will perform a power-on operation and jump to the relevant state, and then report its own status to the HCU. The HCU will detect the status of each component. If any component reports a fault, the HCU will request the Instrument Panel (IP) to issue a relevant alarm. At this time, the vehicle cannot be powered on and the vehicle start indicator (Ready light) will not be illuminated.

[0059] Step 102: If the power system is detected to be operating normally, a request to close the relay is sent to the battery management system (BMS) so that the BMS closes the relay.

[0060] It should be noted that, in the embodiments of this application, if the HCU detects that there are no abnormalities after each component in the power system completes its own state transition, that is, the power system is working normally, the HCU requests the Battery Management System (BMS) to close the relay.

[0061] It should be noted that the Hybrid Control Unit (HCU) is the main controller of the hybrid system, responsible for managing the entire powertrain. Based on the driver's driving intentions, the vehicle's driving status, and the operating status of various vehicle components, it determines operations such as torque distribution between the generator and motor, the opening and closing of high-voltage circuits, engine starting or stopping, and accessory activation. The HCU collects various switch and sensor signals related to vehicle control and achieves coordinated control of the transmission controller (TCU), battery management system (BMS), and motor controller, etc., through command and data exchange via the CAN bus.

[0062] In this embodiment, the BMS is the controller of the power battery. The BMS determines the remaining power of the power battery based on information such as voltage and current. The power battery relay is controlled by the HCU through the BMS to control the opening and closing of the main circuit. At the same time, in the early stage of charging and discharging, the pre-charge relay needs to be closed for pre-charging. Therefore, the process of closing the relay is as follows: the HCU sends a relay closure request to the BMS. After receiving this request, the BMS controls its internal relay to perform the closing action and feeds back the closed status to the BMS.

[0063] Step 103: Obtain the power battery's charge level.

[0064] It should be noted that in step 103, the power battery capacity value is obtained. Specifically, the HCU sends a request to the BMS to obtain the capacity value. The BMS determines the remaining power battery capacity based on information such as voltage and current of the power battery and sends the battery capacity value to the HCU. Therefore, the HCU obtains the power battery capacity value.

[0065] Step 104: Determine the vehicle start indicator status based on the relationship between the power battery charge value and the first preset value, wherein the vehicle start indicator is used to indicate whether the fuel cell vehicle is in a startable state.

[0066] It should be noted that after obtaining the power battery charge value in step 103, the charge value is compared with a first preset value. Based on the comparison result between the charge value and the first preset value, it is determined whether the vehicle start indicator light is turned on. It should be noted that the vehicle start indicator light status refers to the vehicle start indicator light being normally displayed, i.e., lit, or the vehicle start indicator light not being displayed, i.e., off. The vehicle start indicator light is used to indicate whether the fuel cell vehicle is in a startable state.

[0067] In this application embodiment, the first preset value is specifically defined by a first preset value calibrated before the vehicle leaves the factory. The first preset value means that if the vehicle needs to start in pure electric mode, the remaining charge of the power battery must be greater than the first preset value. For example, the charge of the power battery must be greater than 5% (when the vehicle is fully charged, it is 100%) before the vehicle can support pure electric start. In this application embodiment, the first preset value is different for different vehicles, and no specific limitation is made here.

[0068] This application addresses the issue of prior art relying solely on power system malfunction detection upon receiving a vehicle power-on signal. Upon detecting a normal power system operation, it sends a request to the Battery Management System (BMS) to close a relay, causing the BMS to close the relay. It also acquires the battery charge level and, if the battery charge level exceeds a first preset value, controls the vehicle's start indicator light to illuminate. In other words, during vehicle power-on, the HCU detects power system malfunctions. If the power system is functioning normally, the HCU controls the BMS to close a relay. Given a fault-free power system and a properly closed relay, the HCU determines whether the battery charge is sufficient for pure electric drive. If the battery charge exceeds the first preset value, the HCU illuminates the start indicator light, indicating the vehicle is ready to start. This solves the problem of existing technologies that rely solely on power system malfunction detection and relay closure, resulting in indicator light display but failure to start the vehicle, which does not meet regulatory requirements. This application determines whether the vehicle starts normally by obtaining the power battery charge value based on whether the power system is faulty and whether the relay is closed. In other words, by setting the rules for the vehicle start indicator light display, it reduces the misleading effect on the driver caused by the vehicle start indicator light displaying incorrectly due to insufficient power battery charge, thereby improving the user driving experience.

[0069] The second embodiment of this application relates to another method for displaying vehicle indicator lights; see [link to related document]. Figure 2 , Figure 2 This is a flowchart of another vehicle indicator light display method provided in this application embodiment, including the following steps:

[0070] Step 101: Upon receiving a vehicle power-on signal, check for any faults in the powertrain system.

[0071] Step 102: If the power system is detected to be operating normally, a request to close the relay is sent to the battery management system (BMS) so that the BMS closes the relay.

[0072] Step 103: Obtain the power battery's charge level.

[0073] Steps 101-103 above are discussed in the preceding paragraphs and will not be repeated here.

[0074] Step 1041: If the power battery charge value is detected to be greater than the first preset value, control the vehicle start indicator light to display.

[0075] It should be noted that after the HCU obtains the power battery's charge level in step 103, the HCU further needs to determine whether the power battery's charge level can support the pure electric start of the fuel cell vehicle. Specifically, this is determined by a first preset value calibrated before the vehicle leaves the factory. This first preset value represents the minimum remaining charge level of the power battery required for the vehicle to start in pure electric mode. For example, the power battery's charge level must be greater than 5% (100% when the vehicle is fully charged) for the vehicle to support pure electric start. In this embodiment, the first preset value varies depending on the vehicle, and no specific limitation is made here. Therefore, when the power battery's charge level is detected to be greater than the first preset value, the vehicle starts in pure electric mode, and the HCU controls the vehicle's start indicator light to illuminate, i.e., the Ready light illuminates. At this time, the driver can determine whether the vehicle can be driven normally based on the indicator light.

[0076] Step 1042: If the power battery charge value is detected to be less than or equal to the first preset value, control the vehicle start indicator light to display according to the vehicle start status.

[0077] Furthermore, such as Figure 3 As shown, Figure 3 yes Figure 2 A flowchart of a method for displaying vehicle indicator lights according to an exemplary embodiment, step 1042, includes steps 10421-10425.

[0078] Step 10421: If the power battery charge value is detected to be less than or equal to the first preset value, a request to obtain the fuel cell status is sent to the fuel cell controller (FCU) so that the FCU can determine the fuel cell status based on the stack parameters.

[0079] It should be noted that for fuel cell vehicles, since both a power battery and a fuel cell are used for vehicle propulsion, the vehicle can start either on pure electric power or relying on the fuel cell. However, during the initial startup process, the fuel cell still requires power from the power battery. Therefore, when the power battery's charge is insufficient for pure electric startup, the vehicle needs the fuel cell's involvement. It should also be noted that a fuel cell is a device that directly converts the chemical energy of fuel into electrical energy. This conversion is achieved through a redox reaction between the fuel and an oxidant, providing energy to the vehicle for propulsion. The fuel cell can be a hydrogen fuel cell, or a fuel cell using other energy sources such as natural gas, methanol, carbon monoxide, or hydrocarbons. For ease of understanding by those skilled in the art, this application uses pure hydrogen startup as an example of fuel cell startup, but this does not mean that the fuel cell in this application can only be a hydrogen fuel cell.

[0080] Therefore, when the detected charge value of the power battery is less than or equal to the first preset value, the system sends a signal to the fuel cell control unit (FCU). It should be noted that the FCU and BMS correspond to the fuel cell and the power battery, respectively. Therefore, the FCU controls the fuel cell. Before starting the fuel cell, it needs to determine whether a purging action is required. The hydrogen fuel cell engine will perform purging when it is stopped. The gas used for purging is an inert gas, mostly nitrogen, under laboratory conditions. This is to blow out residual water inside the fuel cell to prevent the water from freezing in the flow channel or gas diffusion layer at low temperatures. This would block the gas from reaching the catalyst layer to participate in the electrochemical reaction during low-temperature startup, thus preventing the generation of electricity.

[0081] Therefore, the FCU determines whether purging is necessary based on the internal conditions of the fuel cell. Specifically, the FCU acquires some stack parameters inside the fuel cell, such as the internal temperature, humidity, and hydrogen and oxygen concentrations. It should be noted that the fuel cell stack is the site of electrochemical reactions and the core component of the fuel cell power system. When the FCU determines whether these state parameters meet preset conditions, if they do, it means that the fuel cell does not require purging and can be started directly. If they do not meet the conditions, it means that the fuel cell is in a state awaiting purging and needs to be purged before starting.

[0082] Step 10422: Receive the first fuel cell status returned by the FCU.

[0083] It should be noted that the FCU will determine whether purging is needed based on the internal condition of the fuel cell. Once the FCU has made its determination, it will send the fuel cell status to the HCU. Therefore, the HCU receives the first fuel cell status returned by the FCU.

[0084] Step 10423: If the first fuel cell is detected to be in a state to be purged, determine whether the charge value of the power battery is greater than a second preset value.

[0085] It should be noted that, referring to the explanation in step 10421, when the first fuel cell is in the purging state, it means that the fuel cell stack inside the fuel cell needs to be purged to ensure the normal operation of the fuel cell. However, the purging of the fuel cell also requires power from the power battery to proceed normally, and the normal start-up process of the fuel cell after purging also requires power from the power battery. Therefore, when the first fuel cell is detected to be in the purging state, it is determined whether the power battery's charge value is greater than the second preset value. It should be noted that the second preset value represents the minimum charge value that the power battery must meet if the vehicle starts with pure hydrogen and the vehicle's fuel cell needs to be purged. It can be understood that for the same target vehicle, the second preset value is less than the first preset value. Similarly, the second preset value can be a value calibrated before the vehicle leaves the factory.

[0086] Step 10424: When the power battery is detected to be larger than the second preset value, control the FCU to start the purging function and control the power battery to supply power to the fuel cell.

[0087] Therefore, when the power battery charge is detected to reach the second preset value, the HCU will control the FCU to start the purging function to purge the inside of the fuel cell, and the HCU will control the power battery to supply power to the fuel cell through the BMS.

[0088] Step 10425: If the purging function is detected to be complete and the vehicle is started via the fuel cell, control the vehicle start indicator light to be displayed.

[0089] Since the power battery supplies power to the fuel cell, the purging process inside the fuel cell can be completed, and the fuel cell can start the vehicle. Therefore, when the purging function is detected to be complete and the vehicle is started by the fuel cell, it means that the vehicle can be started with pure hydrogen, and the vehicle start indicator light, i.e., the Ready light, will illuminate.

[0090] Furthermore, for the target vehicle, starting the vehicle with pure hydrogen may require purging the fuel cell stack. If the internal conditions of the fuel cell stack meet preset conditions, the FCU does not need to purge the stack. In this case, the vehicle start indicator light will illuminate, and the specific process of starting the vehicle with pure hydrogen will be as follows: Figure 4 As shown, Figure 4 yes Figure 2According to an exemplary embodiment, another method flowchart of step 1042 in another vehicle indicator light display method is shown, which further includes steps 10421-10429.

[0091] Step 10421: If the power battery charge value is detected to be less than or equal to the first preset value, a request to obtain the fuel cell status is sent to the fuel cell controller (FCU) so that the FCU can determine the fuel cell status based on the stack parameters.

[0092] The above steps 10421 are discussed in the preceding paragraphs and will not be repeated here.

[0093] Step 10426: Receive the second fuel cell status returned by the FCU.

[0094] Step 10427: If the state of the second fuel cell is found to meet the preset conditions, determine whether the charge value of the power battery is greater than a third preset value.

[0095] Step 10428: If the power battery charge value is detected to be greater than a third preset value, control the power battery to supply power to the fuel cell.

[0096] Step 10429: If the vehicle is detected to be started by the fuel cell, control the vehicle start indicator light to be displayed.

[0097] In steps 10426-10429, the HCU receives the second fuel cell status returned by the FCU. The second fuel cell status meets the preset conditions, which means that the FCU does not need to perform purging work on the inside of the fuel cell stack. At this time, the power battery only needs to supply power to the fuel cell when it starts up, and does not need to provide the power required for the purging function. At this time, the third preset value represents the minimum amount of power required by the power battery if the vehicle starts with pure hydrogen and does not need to perform fuel cell purging work. Therefore, when the power battery's power value is detected to be greater than the third preset value, the HCU controls the power battery to supply power to the fuel cell through the BMS. When the vehicle can start with pure hydrogen, the HCU controls the vehicle start indicator light to illuminate, that is, the Ready light is turned on.

[0098] This application determines whether the vehicle can start normally by obtaining the power battery charge value based on whether the power system is faulty and whether the relay is closed. If the vehicle cannot start purely on electric power, the vehicle start indicator light will not illuminate. The HCU needs to further determine whether the vehicle can start purely on hydrogen and then control whether the vehicle start indicator light illuminates. By setting the rules for the vehicle start indicator light display, the application reduces the possibility of the start indicator light misleading the driver due to insufficient power battery charge, thereby improving the user's driving experience.

[0099] The third embodiment of this application relates to another method for displaying vehicle indicator lights, see [link to relevant documentation]. Figure 5 , Figure 5 This is a flowchart of another vehicle indicator light display method provided in this application embodiment, including the following steps:

[0100] Step 101: Upon receiving a vehicle power-on signal, check for any faults in the powertrain system.

[0101] Step 102: If the power system is detected to be operating normally, a request to close the relay is sent to the battery management system (BMS) so that the BMS closes the relay.

[0102] Step 103: Obtain the power battery's charge level.

[0103] Step 10421: If the power battery charge value is detected to be less than or equal to the first preset value, a request to obtain the fuel cell status is sent to the fuel cell controller (FCU) so that the FCU can determine the fuel cell status based on the stack parameters.

[0104] The steps 101-10421 above are discussed in the preceding paragraphs and will not be repeated here.

[0105] Step 104210: If the power battery charge value is detected to be less than the target threshold, a warning command is sent to the vehicle dashboard to make the vehicle dashboard display warning information, wherein the target threshold includes a second preset value or a third preset value.

[0106] It should be noted that, in this embodiment of the application, when the power battery charge value is detected to be less than the target threshold, a warning command is sent to the vehicle dashboard, and the vehicle dashboard displays a warning message to remind the driver that the vehicle's power battery charge is insufficient and that it cannot start on pure electric or pure hydrogen.

[0107] Therefore, the target threshold in this application embodiment may include a second preset value and a third preset value. That is, if the vehicle cannot start with pure electric power, it also cannot start with pure hydrogen power. At this time, the vehicle indicator light will not be displayed, that is, the vehicle Ready light will not be lit, and the vehicle will not be able to start.

[0108] This application determines whether the vehicle can start normally by obtaining the power battery charge value based on whether the power system is faulty and whether the relay is closed. If the vehicle cannot start purely on electric power, the vehicle start indicator light will not illuminate. The HCU needs to further determine whether the vehicle can start purely on hydrogen and then control whether the vehicle start indicator light illuminates. By setting the rules for the vehicle start indicator light display, the application reduces the misleading information to the driver caused by insufficient power battery charge, improves the user driving experience, and displays warning information on the vehicle dashboard to further remind the driver that the vehicle has insufficient power battery charge and cannot start.

[0109] It should be noted that all embodiments in this example are only for the purpose of enabling those skilled in the art to better understand the technical solutions in this example, and are not intended to limit the structure in this example.

[0110] The fourth embodiment of this application relates to a vehicle indicator light display device, such as... Figure 6 As shown, Figure 6 This is a block diagram of a vehicle indicator light display device according to an exemplary embodiment, the device including the following modules:

[0111] The detection module 601 is used to detect whether there is a fault in the power system when a vehicle power-on signal is received;
