[0026] The following describes a method for controlling a vehicle according to an embodiment of the present invention with reference to the accompanying drawings.

[0027] Reference Figure 1 As shown, the vehicle according to the embodiment of the present invention is operated by the control method of the vehicle according to the embodiment of the present invention, and the vehicle includes a fuel cell system and a battery pack. The vehicle has a fuel cell system power supply mode and a battery pack power supply mode. By selecting different power supply modes, different power supply modes of the vehicle can be realized to meet different user needs. When the vehicle adopts the fuel cell system power supply mode, zero emissions can be achieved, which is conducive to reducing greenhouse gas emissions and making the vehicle run smoothly and without noise; when the vehicle adopts the battery pack power supply mode, it is conducive to increasing power, ensuring stability in use, good reliability, and long service life.

[0028] The control method according to an embodiment of the present invention includes:

[0029] Determine whether the area where the vehicle is located is a high-pollution area. In other words, when the vehicle starts to start, or during the vehicle's starting process, it can be determined whether the area where the vehicle is located is a high-pollution area;

[0030] If yes, the vehicle adopts the battery pack power supply mode, that is, the battery pack is controlled to work to realize power supply to the vehicle, or the vehicle can adopt the battery pack power supply mode and the fuel cell system power supply mode at the same time, that is, the battery pack and the fuel cell system are controlled to work at the same time to realize power supply to the vehicle, for example, the battery pack can be a lithium-ion battery or a storage battery, etc.;

[0031] If not, the vehicle adopts the fuel cell system power supply mode, that is, the fuel cell system is controlled to work to power the vehicle.

[0032] Therefore, when the vehicle is in a high-pollution area, by controlling the vehicle to adopt the battery pack power supply mode or the battery pack power supply mode and the fuel cell system power supply mode at the same time, it is possible to avoid or reduce the problem of the fuel cell system inhaling air pollutants due to the use of the fuel cell system power supply mode, thereby avoiding or reducing the entry of air pollutants into the fuel cell system and easily reducing the service life and performance of the fuel cell system, ensuring the operational reliability of the fuel cell system, and eliminating the need for redesign of other structures, which is conducive to reducing development costs.

[0033] According to the vehicle control method of the embodiment of the present invention, it is determined whether the area where the vehicle is located is a high-pollution area; if so, the vehicle adopts the battery pack power supply mode or the battery pack power supply mode and the fuel cell system power supply mode at the same time; if not, the vehicle adopts the fuel cell system power supply mode. Therefore, when the vehicle is in a high-pollution area, by controlling the vehicle to adopt the battery pack power supply mode or the battery pack power supply mode and the fuel cell system power supply mode at the same time, it is possible to avoid or reduce the problem of the fuel cell system inhaling air pollutants due to the use of the fuel cell system power supply mode, which is beneficial to improving the service life and performance of the fuel cell system, ensuring the operational reliability of the fuel cell system, and reducing development costs.

[0034] Since the control method of the vehicle according to the embodiment of the present invention has the above-mentioned beneficial technical effects, the vehicle according to the embodiment of the present invention determines whether the area where the vehicle is located is a high-pollution area; if so, the vehicle adopts the battery pack power supply mode or adopts the battery pack power supply mode and the fuel cell system power supply mode at the same time; if not, the vehicle adopts the fuel cell system power supply mode. Therefore, when the vehicle is in a high-pollution area, by controlling the vehicle to adopt the battery pack power supply mode or adopting the battery pack power supply mode and the fuel cell system power supply mode at the same time, it is possible to avoid or reduce the problem of the fuel cell system inhaling air pollutants due to the use of the fuel cell system power supply mode, which is beneficial to improving the service life and performance of the fuel cell system, ensuring the operational reliability of the fuel cell system, and helping to reduce development costs.

[0035] In some embodiments of the present invention, Figure 1 As shown, judging whether the area where the vehicle is located is a high-pollution area includes:

[0036] The current location of the vehicle can be accurately obtained by obtaining the current location of the vehicle through the vehicle's Global Positioning System (GPS);

[0037] Whether the current area is a high-pollution area can be determined based on the current area. In other words, whether the area where the vehicle is located is a high-pollution area can be determined directly through the vehicle's positioning information, making it simpler and more convenient to obtain the concentration of air pollutants, facilitating subsequent control of the vehicle, and helping to reduce the production cost of the vehicle.

[0038] In some embodiments, network information is used to determine whether the current area is a high-pollution area. Thus, by combining the vehicle positioning information obtained by the global positioning system with the network information of the corresponding area, the air pollutant concentration corresponding to the current area can be obtained, making it simpler and more convenient to obtain the air pollutant concentration, which is beneficial to reducing the production cost of the vehicle.

[0039] According to some embodiments of the present invention, Figure 1 As shown, judging whether the area where the vehicle is located is a high-pollution area includes:

[0040] Obtaining the concentration of air pollutants in the area where the vehicle is located. In other words, when the vehicle starts to start or during the starting process of the vehicle, the concentration of air pollutants in the area where the vehicle is located can be obtained;

[0041] Determine whether the concentration of air pollutants is greater than a preset concentration;

[0042] If it is determined that the area where the vehicle is located is a high-pollution area, the concentration of air pollutants can be judged to achieve the determination of the high-pollution area, making the judgment more accurate, and effectively avoiding or reducing the problem of the fuel cell system inhaling air pollutants due to the use of the fuel cell system power supply mode, thereby ensuring the operating reliability of the fuel cell system.

[0043] It should be noted that "obtaining the concentration of air pollutants in the area where the vehicle is located" here can be to continuously obtain the concentration of air pollutants in the area where the vehicle is located, or to obtain the concentration of air pollutants in the area at set intervals. For example, the concentration of air pollutants in the area where the vehicle is located can be obtained once every set time (for example, 1 second, 2 seconds, 3 seconds).

[0044] In some embodiments, the specific value of the preset concentration can be set according to actual conditions. For example, the preset concentration can be set before leaving the factory to avoid high concentrations of air pollutants in the area where the vehicle is located, which may affect the service life and performance of the fuel cell system.

[0045] According to some embodiments of the present invention, the vehicle includes a detection module, and obtaining the concentration of air pollutants in the area where the vehicle is located includes:

[0046] By detecting the concentration of air pollutants in the area where the vehicle is located through the detection module, the concentration of air pollutants in the area where the vehicle is located can be accurately obtained, which is convenient for detecting the concentration of air pollutants. It can meet the required needs of obtaining the concentration of air pollutants in the area where the vehicle is located, and has a simple structure, which is conducive to reducing production costs.

[0047] In some embodiments of the present invention, the fuel cell system includes a fuel cell stack and an air filter, and the outlet of the air filter is connected to the air inlet of the fuel cell stack, so that external air can enter the air filter for filtration and enter the fuel cell stack through the outlet of the air filter and the air inlet of the fuel cell stack, thereby realizing the normal operation of the fuel cell system. The air filter can absorb harmful gases in the air, remove dust and other particulate matter in the air, and ensure the purity of the air flowing out of the air filter.

[0048] In addition, when the concentration of air pollutants is greater than the preset concentration, by controlling the vehicle to use the battery pack power supply mode, it is possible to avoid problems such as the air filter absorbing more air pollutants and reducing its service life, thereby ensuring the operational reliability of the fuel cell system.

[0049] According to some embodiments of the present invention, Figure 2 As shown, the control method also includes:

[0050] Determining that the cumulative mileage of the vehicle in the fuel cell system power supply mode is greater than the preset mileage;

[0051] Generate a reminder message for replacing the air filter so that the user can replace the air filter in time after receiving the reminder message, avoid saturation of the air filter and affect the filtering effect of the air filter, and ensure the operational reliability of the fuel cell system.

[0052] In some embodiments, the specific value of the preset mileage can be set according to actual conditions, for example, the preset mileage can be set before leaving the factory to prevent the air filter from becoming saturated and affecting the filtering effect of the air filter. For example, the preset mileage can be 20,000 km.

[0053] In some embodiments, Figure 3 As shown, the control method includes:

[0054] Get the current saturation level of the air filter;

[0055] When the current saturation level of the air filter is equal to the maximum saturation level of the air filter, a prompt message for replacing the air filter is generated so that the user can replace the air filter in time after receiving the prompt message, thereby avoiding the saturation of the air filter and affecting the filtering effect of the air filter, thereby ensuring the operating reliability of the fuel cell system.

[0056] At the same time, by judging the current saturation level of the air filter and generating a reminder message for replacing the air filter, it is possible to avoid problems such as contamination of the fuel cell stack caused by the air filter being saturated for a long time without being replaced, and to avoid reducing the power of the fuel cell stack, so that the air filter can be replaced more timely, or the air filter can be replaced when it is not saturated, thereby avoiding waste caused by replacing the air filter too early, which is beneficial to reducing the user's additional service costs.

[0057] In some embodiments, the reminder information may include various modules to ensure that the user can find the reminder to replace the air filter in time.

[0058] In some embodiments of the present invention, the prompt information may be an indicator light displayed on the dashboard of the vehicle, so that the user can replace the air filter in time after observing that the indicator light on the dashboard is on, so as to avoid saturation of the air filter and affect the filtering effect of the air filter, thereby ensuring the service life and performance of the fuel cell system. For example, the indicator light may be a constant light, a flashing light, a digital display, a text display, an icon display, etc.

[0059] According to some embodiments of the present invention, the prompt information may be a prompt tone, so that the user can replace the air filter in time after hearing the prompt tone, so as to avoid the air filter from becoming saturated and affecting the filtering effect of the air filter, thereby ensuring the service life and performance of the fuel cell system. For example, the prompt tone may be a voice reminder and a ring tone reminder.

[0060] In some embodiments, the prompt information may include both an indicator light and a prompt sound, and may provide a reminder in a variety of ways to avoid neglect that may affect the filtering effect of the air filter after the air filter is saturated.
