[0023] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0024] Hydrogen-powered vehicles mainly use 35MPa or 70MPa high-pressure gaseous hydrogen storage. Due to the flammable and explosive properties of hydrogen, the monitoring and treatment of hydrogen leakage and exhaust concentration are particularly important. In general, high-precision hydrogen concentration sensors are often used to monitor whether hydrogen-powered vehicles have hydrogen leakage. In related technologies, multiple hydrogen concentration sensors are usually arranged near the fuel cell engine and the hydrogen storage bottle. When hydrogen leakage occurs at any monitored location, safety measures can be taken to ensure the safety of the vehicle and passengers.

[0025] In the related technology, the collected values ​​of multiple hydrogen concentration sensors are mainly processed by the hydrogen system controller HMS (Hydrogen Management System), and the maximum value is taken as the alarm value of hydrogen leakage. The hydrogen system controller will report the maximum value to the fuel cell controller FCU (Fuel Cell Unit) and the vehicle controller VCU (Vehicle Control Unit). When the maximum value exceeds the limit, the hydrogen system controller will also send an alarm message to the instrument ICU (Instrument Cluster Unit) and take corresponding measures.

[0026] However, the inventors found that when checking whether there is hydrogen leakage around hydrogen-powered vehicles through related technical methods, the monitoring is all done when the vehicle is powered. When the vehicle is parked and the doors are locked, the high and low voltage power supply units are turned off, and the driver leaves, low-voltage components such as hydrogen concentration sensors and hydrogen system controllers will not work without power, and it will be impossible to monitor whether the vehicle has hydrogen leakage, which will bring greater safety risks of hydrogen leakage.

[0027] In view of this, the present disclosure provides a vehicle monitoring system, method, storage medium, vehicle and program product to solve the technical problems existing in the above-mentioned related technologies.

[0028] like Figure 1 As shown, Figure 1 is a schematic diagram showing a vehicle monitoring system according to an exemplary embodiment of the present disclosure, referring to Figure 1 , including a low-voltage battery 2, a low-voltage battery controller 3, a vehicle controller 4 and a hydrogen concentration sensor 1, wherein the output end of the low-voltage battery 2 is respectively connected to the input end of the low-voltage battery controller 3 and the input end of the hydrogen concentration sensor 1, the output end of the low-voltage battery controller 3 is connected to the input end of the vehicle controller 4, and the vehicle controller 4 is connected to the low-voltage battery 2; The low-voltage battery controller 3 is used to obtain the charge state of the low-voltage battery 2 when the vehicle is in a power-off state, and transmit the charge state to the vehicle controller 4; The vehicle controller 4 is used to control the low-voltage battery 2 to supply power to the low-voltage battery controller 3, the vehicle controller 4 and the hydrogen concentration sensor 1 according to the state of charge, so as to monitor the hydrogen concentration of the environment where the vehicle is located.

[0029] Through the above technical solution, when the vehicle is in a power-off state, the charge state of the low-voltage battery 2 is obtained through the low-voltage battery controller 3, and the charge state is transmitted to the vehicle controller 4. The vehicle controller 4 controls the low-voltage battery 2 to supply power to the low-voltage battery controller 3, the vehicle controller 4 and the hydrogen concentration sensor 1 according to the charge state to monitor the hydrogen concentration of the vehicle's environment. By controlling the low-voltage battery 2 to supply power to the low-voltage battery controller 3, the vehicle controller 4 and the hydrogen concentration sensor 1 when the vehicle is powered off to monitor the hydrogen concentration of the vehicle's environment, it is possible to monitor whether the vehicle has hydrogen leakage around the clock, thereby reducing the risk of hydrogen leakage when the vehicle is parked and powered off, and at the same time, it is also possible to improve the hydrogen safety of the vehicle.

[0030] In order to enable those skilled in the art to better understand the vehicle monitoring system provided by the present disclosure, the above steps are described in detail with examples below.

[0031] For example, the low-voltage battery 2 can be used as a device to provide power to the low-voltage electrical system in the vehicle. Among them, the low-voltage battery 2 can be a 12V lead-acid battery or a lithium-ion battery, which is not specifically limited in the embodiments of the present disclosure. The low-voltage battery controller 3 can be used to manage and monitor the status of the low-voltage battery 2 to ensure the stability and safety of the operation of the low-voltage battery 2. The vehicle controller 4 can be used to coordinate and manage various systems in the vehicle. The hydrogen concentration sensor 1 can be used to monitor and control the hydrogen supply.

[0032] The power-off state may be the state in which the high and low voltage power supply units are turned off when the vehicle is parked and the doors are locked. In the embodiment of the present disclosure, when the vehicle is in the power-off state, the state of charge of the low-voltage battery 2 can be obtained by the low-voltage battery controller 3, and the state of charge can be transmitted to the vehicle controller 4. When the low-voltage battery controller 3 obtains the state of charge of the low-voltage battery 2, the low-voltage battery controller 3 can be controlled to obtain the state of charge of the low-voltage battery 2 according to the preset time, so as to monitor the voltage of the low-voltage battery 2 in real time, so as to avoid the low-voltage battery 2 from running out of power, and thus protect the service life of the low-voltage battery 2. Among them, the preset time length can be 10s or 30s, and the embodiment of the present disclosure does not make any specific limitation on this.

[0033] After receiving the state of charge, the vehicle controller 4 can control the low-voltage battery 2 to supply power to the low-voltage electrical module in the vehicle according to the state of charge. The low-voltage electrical module may include a low-voltage battery controller 3, a vehicle controller 4, and a hydrogen concentration sensor 1. The disclosed embodiment does not specifically limit this. The vehicle may be a hydrogen energy vehicle. The disclosed embodiment does not specifically limit this.

[0034] When the hydrogen concentration sensor 1 is powered by the low-voltage battery 2, it can be ensured that the hydrogen concentration sensor 1 monitors the hydrogen concentration of the vehicle in a power-off state. Among them, multiple hydrogen concentration sensors 1 can be set, or one can be set. The hydrogen concentration sensor 1 can be set near the fuel cell engine of the vehicle, or near the hydrogen storage bottle, and this is not specifically limited in the embodiments of the present disclosure.

[0035] When the vehicle is in a power-off state, the low-voltage battery 2 is controlled to supply power to the low-voltage battery controller 3, the vehicle controller 4 and the hydrogen concentration sensor 1 according to the charge state of the low-voltage battery 2, so as to monitor the hydrogen concentration in the vehicle's environment. This can achieve all-weather monitoring of whether there is hydrogen leakage in the vehicle, thereby reducing the risk of hydrogen leakage when the vehicle is parked and powered off, and at the same time can improve the hydrogen safety of the vehicle.

[0036] In a possible manner, the vehicle controller 4 is used to: When the state of charge is greater than or equal to a preset state of charge, the low-voltage battery 2 is controlled to supply power to the low-voltage battery controller 3, the vehicle controller 4 and the hydrogen concentration sensor 1; When the state of charge is less than a preset state of charge, the vehicle's power battery is controlled to supplement the low-voltage battery 2, and when the state of charge is greater than or equal to the preset state of charge, the low-voltage battery 2 is controlled to supply power to the low-voltage battery controller 3, the vehicle controller 4 and the hydrogen concentration sensor 1.

[0037] It should be understood that the state of charge (SOC) is the ratio between the remaining capacity of the low-voltage battery and its capacity in a fully charged state. The preset state of charge can be the lowest state of charge of the low-voltage battery 2 under normal power supply conditions. When the state of charge is greater than the preset state of charge, it can represent that the low-voltage battery 2 can normally supply power to each module in the low-voltage electrical system. At this time, the low-voltage battery 2 can be directly controlled to supply power to the low-voltage battery controller 3, the vehicle controller 4 and the hydrogen concentration sensor 1 to monitor the hydrogen concentration in the vehicle's environment.

[0038] When the state of charge is less than the preset state of charge, it means that the low-voltage battery 2 cannot supply power to each module in the low-voltage electrical system. At this time, the vehicle's power battery can be controlled to supplement the low-voltage battery 2, and when the state of charge is greater than or equal to the preset state of charge, the low-voltage battery 2 can be controlled to supply power to the low-voltage battery controller 3, the vehicle controller 4 and the hydrogen concentration sensor 1 to monitor the hydrogen concentration in the environment where the vehicle is located. Among them, the power battery can be used as a battery system to provide electrical energy to the vehicle.

[0039] By comparing the state of charge with the preset state of charge and then controlling the power supply mode of the low-voltage battery 2, the low-voltage power supply demand of the low-voltage battery 2 can be ensured, and the low-voltage battery 2 can be intelligently replenished.

[0040] In a possible manner, the low-voltage battery controller 3 is used to generate a supplementary power request signal according to the state of charge when the state of charge is less than the preset state of charge, and input the supplementary power request signal to the vehicle controller 4; The vehicle controller 4 is also used for: After receiving the power replenishment request signal, the power battery of the vehicle is controlled to charge the low-voltage battery 2 according to the charge state, and when the charge state is greater than the preset charge state, the power battery of the vehicle is controlled to stop charging the low-voltage battery 2.

[0041] It should be understood that after the low-voltage battery controller 3 obtains the state of charge of the low-voltage battery 2, it compares the state of charge with the preset state of charge. When the state of charge is less than the preset state of charge, the low-voltage battery controller 3 can generate a power replenishment request signal according to the state of charge, and input the power replenishment request signal into the vehicle controller 4. Among them, the power replenishment request signal can be a signal requesting the power battery to enable the low-voltage battery 2 with high voltage, and this embodiment of the present disclosure does not make specific limitations on this.

[0042] After receiving the charging request signal, the vehicle controller 4 controls the vehicle's power battery to charge the low-voltage battery 2. After that, the state of charge of the low-voltage battery 2 can be continuously monitored, and the state of charge can be compared with the preset state of charge. When the state of charge is greater than the preset state of charge, it can represent that the state of charge of the low-voltage battery 2 at this time satisfies the energy for providing output power to the outside. At this time, the power battery can be stopped from charging the low-voltage battery 2.

[0043] The low-voltage battery controller 3 sends a power replenishment request signal to the vehicle controller 4, and the vehicle controller 4 controls the power battery to replenish the low-voltage battery 2, so that the low-voltage battery 2 supplies power to the low-voltage battery controller 3, the hydrogen concentration sensor 1 and the vehicle controller 4, and then when the vehicle is in a power-off state, it can monitor whether there is hydrogen leakage in the vehicle, and then it can monitor whether there is hydrogen leakage around the vehicle in real time, which can improve the hydrogen safety of the vehicle. At the same time, it can also reduce the hidden dangers of hydrogen leakage and improve the hydrogen safety of the vehicle.

[0044] In a possible manner, the vehicle monitoring system further includes a hydrogen system controller 5, the input end of the hydrogen system controller 5 is respectively connected to the output end of the hydrogen concentration sensor 1 and the output end of the low-voltage battery 2, and the output end of the hydrogen system controller 5 is connected to the input end of the vehicle controller 4; The hydrogen concentration sensor 1 is used to detect the hydrogen concentration of the environment where the vehicle is located, and transmit the hydrogen concentration to the hydrogen system controller 5; The hydrogen system controller 5 is used to generate early warning fault information according to the hydrogen concentration and the preset early warning fault condition, and send the early warning fault information to the vehicle controller 4; The vehicle controller 4 is used to send the warning fault information to the terminal to remind relevant personnel to handle it; The low-voltage battery 2 is used to supply power to the hydrogen system controller 5 when the vehicle is in a power-off state.

[0045] It should be understood that when a vehicle has a hydrogen leak and the concentration of the leaked hydrogen reaches a certain threshold, the vehicle is in a relatively dangerous environment. Therefore, it is necessary to monitor in real time whether there is hydrogen around the vehicle and the concentration of the leaked hydrogen when the vehicle has a hydrogen leak, so that relevant operators can handle it in time after receiving the hydrogen concentration information.

[0046] The hydrogen system controller 5 can be used to manage and control the equipment of the hydrogen energy system. When the hydrogen concentration sensor 1 detects the hydrogen concentration, the hydrogen concentration can be transmitted to the hydrogen system sensor. The hydrogen system controller 5 can generate corresponding early warning fault information according to the hydrogen concentration and the preset early warning fault condition, and send the early warning fault information to the vehicle controller 4. The vehicle controller 4 sends the early warning fault information to the terminal for relevant personnel to handle. Among them, the early warning fault information can be fault information of different levels, and the higher the level, the more serious the hydrogen leakage fault. The terminal can be a cloud platform 7 or a terminal device. The terminal device can be a mobile phone, a computer, and a tablet. This is not specifically limited in the embodiments of the present disclosure.

[0047] The low-voltage battery 2 can also supply power to the hydrogen system controller 5 in real time, so that the hydrogen system controller 5 can compare the received hydrogen concentration with the preset warning fault condition in real time, and then when the vehicle is in a power-off state, it can judge in real time whether there is a hydrogen leak around the vehicle, and when there is a hydrogen leak around the vehicle, whether the leaked hydrogen concentration needs to be handled in time, thereby reducing safety hazards.

[0048] In a possible manner, the hydrogen system controller 5 is further configured to: When the hydrogen concentration is greater than a first preset threshold and less than a second preset threshold, generating a first warning fault information; When the hydrogen concentration is greater than the second preset threshold, second early warning fault information is generated, and the first early warning fault information and the second early warning fault information have different fault levels.

[0049] It should be understood that in the hydrogen system controller 5, when the early warning fault information is generated according to the hydrogen concentration and the preset early warning fault condition, when the hydrogen concentration is greater than the first preset threshold and less than the second preset threshold, it can represent that the hydrogen leakage of the vehicle may fail, and the first early warning fault information can be generated, wherein the first preset threshold can be a specific value, and the second preset threshold can be a specific number, for example, the first preset threshold can be 0.4%, and the second preset threshold can be 1%. When the hydrogen concentration is greater than the second preset threshold, it can represent that the hydrogen leakage of the vehicle has a serious fault, and the second early warning fault information can be generated. Among them, the fault severity of the second early warning fault information is greater than the fault severity of the first early warning fault information.

[0050] Different early warning fault information is generated according to different hydrogen concentrations and sent to the terminal, which can remind relevant personnel to adopt different methods to deal with them in a timely manner according to different early warning fault information, thereby improving hydrogen safety.

[0051] In a possible manner, the vehicle monitoring system further comprises a telematics processing module 6, the input end of the telematics processing module 6 is respectively connected to the output end of the low-voltage battery 2 and the output end of the vehicle controller 4, and the output end of the telematics processing module 6 is connected to the terminal; The vehicle controller 4 is used to report the early warning fault information to the cloud platform 7 through the remote information processing module 6, so that the cloud platform 7 sends the early warning fault information to the terminal; The low-voltage battery 2 is used to supply power to the telematics module 6 when the vehicle is in a power-off state.

[0052] It should be understood that the telematics module 6T-BOX (Telematics Box) can be used as a module for vehicle remote communication and data management. Figure 2 As shown, when the vehicle controller 4 transmits the warning fault information, the warning fault information can be sent to the cloud platform 7 through the remote information processing module 6, so that the cloud platform 7 sends the warning fault information to the terminal. For example, the cloud platform 7 can send the warning fault information to the APP (Application) of the client 8, and the APP of the client 8 can broadcast the warning fault information or issue a related prompt sound to remind the driver that the vehicle has a hydrogen leak and needs to be handled in time.

[0053] The remote information processing module 6 is powered by the low-voltage battery 2, and can transmit the warning fault information to the APP of the client 8 in real time when the vehicle is in a power-off state, so as to promptly remind the driver that there is a hydrogen leak in the vehicle and timely processing is required.

[0054] In actual applications, when the vehicle is powered off and stored, the vehicle cannot be powered by low voltage, which causes the hydrogen concentration sensor 1, vehicle controller 4, hydrogen system controller 5, fuel cell controller 9 and other controllers to fail to work properly. In order to ensure that hydrogen safety is under real-time monitoring, such as Figure 2As shown, the low-voltage battery controller 3 is connected to the low-voltage battery 2, and the state of charge (SOC_act value) of the low-voltage battery 2 is monitored by the low-voltage battery controller 3, and the state of charge of the low-voltage battery 2 is fed back to the vehicle controller 4. Among them, the low-voltage battery controller 3 can be awakened once every 10s or 30s to detect the state of charge of the low-voltage battery 2 to ensure that the low-voltage battery 2 can continue to supply power to the low-voltage controller, such as Figure 3 As shown, the fuel cell controller 9 can be used to manage and monitor the equipment of the fuel cell system.

[0055] The specific working principle of the vehicle monitoring system is as follows Figure 4 As shown, when the low-voltage battery controller 3 detects that the state of charge of the low-voltage battery 2 is higher than the preset state of charge, the hydrogen concentration sensor 1, the hydrogen system controller 5, the vehicle control, and the telematics processing module 6 are all in a power supply state. Among them, the hydrogen system controller 5 determines the level of hydrogen leakage fault of the vehicle by the hydrogen concentration in different areas sent by the hydrogen concentration sensor 1. When the hydrogen concentration in the air is between 0.4% and 1%, the warning fault information is determined to be level 1 hydrogen leakage fault information, and the hydrogen system controller 5 can report the level 1 hydrogen leakage fault information to the vehicle controller 4, and the vehicle controller 4 can report to the cloud platform 7 through the telematics processing module 6. The APP distributed by the cloud platform 7 to the client 8 displays the hydrogen leakage abnormality and asks for maintenance to prompt the driver, wherein the level 1 hydrogen leakage fault information can be the first warning fault information. When the hydrogen concentration in the air is above 1%, the warning fault information can be determined to be level 2 hydrogen leakage fault information. The hydrogen system controller 5 will report the level 2 hydrogen leakage fault information to the vehicle controller 4. The vehicle controller 4 will report it to the cloud platform 7 through the remote information processing module 6. The APP distributed by the cloud platform 7 to the user client 8 shows that it needs to be processed immediately and continues to buzz to remind the driver. Among them, the level 2 hydrogen leakage fault information can be the second warning fault information.

[0056] When the low-voltage battery controller 3 detects that the state of charge of the low-voltage battery 2 is lower than the preset state of charge, the low-voltage battery controller 3 will send a charging request signal to the vehicle controller 4. After comprehensively judging the vehicle status, the vehicle controller 4 will increase the high voltage and enable the DCDC converter (DC-DC Converter) to charge the low-voltage battery 2. This monitoring method can always ensure that the low-voltage battery 2 has sufficient power, and can achieve the effect of full-time domain monitoring of hydrogen leakage in the whole vehicle, thereby improving hydrogen safety.

[0057] Through the above technical solution, in the vehicle monitoring system, a low-voltage battery controller 3 is set to monitor the charge state of the low-voltage battery 2, and according to the charge state and the preset charge state, the power supply of the low-voltage battery 2 is controlled by the vehicle controller 4, so that the vehicle can be monitored in real time whether there is hydrogen leakage after the vehicle is parked and the power is turned off, thereby filling the hidden danger of hydrogen leakage when the vehicle is parked and powered off, and improving the safety of hydrogen use, and improving the feasibility and scalability of the vehicle monitoring system. At the same time, the low-voltage battery 2 can be replenished in real time according to the charge state of the low-voltage battery 2, thereby ensuring the low-voltage power supply demand of the low-voltage battery 2.

[0058] Based on the same concept, this embodiment also provides a vehicle monitoring method, such as Figure 5 As shown, Figure 5 is a schematic diagram showing a vehicle monitoring method according to an exemplary embodiment of the present disclosure, with reference to Figure 5 , the vehicle monitoring method comprises: S501: When the vehicle is in a power-off state, determining the charge state of the low-voltage battery 2 of the vehicle; S502: According to the state of charge, control the low-voltage battery 2 to supply power to the low-voltage battery controller 3, the vehicle controller 4 and the hydrogen concentration sensor 1 to monitor the hydrogen concentration of the environment where the vehicle is located.
