[0056] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0057] Before providing a detailed explanation of the power supply method and system for an AR-HUD system provided in the embodiments of this application, the application scenarios provided in the embodiments of this application will be described first.

[0058] With the continuous development of society, automobiles have become an indispensable means of transportation in people's daily lives. Consequently, traffic safety issues are becoming increasingly serious, and traffic accidents have become the leading cause of death and property loss in today's society. Therefore, vehicle safety has become a major direction for future automotive development. AR-HUD systems are a type of automotive visual safety driving system. This system projects important information needed by the driver onto the windshield through its light path, eliminating the need for the driver to look down at the dashboard and allowing them to keep their eyes focused on the road ahead, reducing the impact of looking down on safe driving. However, with the increasing number of electrical appliances in automobiles, power imbalances in the vehicle's electrical system can occur, leading to low voltage and causing some electrical appliances to malfunction. This affects the virtual image display of the AR-HUD system, thus posing a threat to driving safety and comfort.

[0059] Based on this application scenario, this application provides a power supply method and system for an AR-HUD system that improves power supply safety and reliability.

[0060] Figure 1 This is a schematic diagram of the power supply system of an AR-HUD system provided in an embodiment of this application. See also... Figure 1 The power supply system is installed in the vehicle and includes a first battery 1, a second battery 2, a backup power supply 3, and a power controller 4. The power controller 4 is connected to the first battery 1, the second battery 2, and the backup power supply 3. The first battery 1 is a battery that supplies power to the AR-HUD system 5 in the vehicle, the second battery 2 is a battery that supplies power to the electrical appliances in the vehicle, and the backup power supply 3 is used to charge the first battery 1 and the second battery 2.

[0061] In this embodiment, since the car is equipped with a backup power supply that can charge the first battery, when the first battery's charge is insufficient to support the car's AR-HUD system, the backup power supply can charge the first battery, thereby ensuring that the first battery meets the power requirements for powering the AR-HUD system. This improves the situation where the AR-HUD system's display status is unstable due to low battery, thereby enhancing driving safety and comfort.

[0062] It should be noted that the first battery 1 is a battery dedicated solely to powering the AR-HUD system in the vehicle; that is, the first battery 1 is the built-in small battery of the AR-HUD system, specifically used to power the AR-HUD system. The second battery 2 is a battery that powers the electrical appliances in the vehicle; that is, the second battery 2 powers all electrical appliances in the vehicle except for the AR-HUD system.

[0063] In some embodiments, the power controller 4 can acquire the power status of the first battery 1, the second battery 2, and the backup power supply 3 in the vehicle; when the first battery 1 is less than the power threshold, the power controller 4 can process the first battery 1 according to the power status of the second battery 2 and the backup power supply 3, and supply power to the AR-HUD system 5 through the first battery 1.

[0064] As an example, when the charge of the first battery 1 is less than the charge threshold and the charge of the backup power supply 3 is greater than or equal to the charge threshold, the power controller 4 can control the backup power supply 3 to charge the first battery 1; when the charge of the first battery 1 and the charge of the backup power supply 3 are less than the charge threshold and the charge of the second battery 2 is greater than or equal to the charge threshold, the second battery 2 is controlled to charge the first battery.

[0065] When the charge level of the first battery 1 is less than the charge threshold, it indicates that the charge level of the first battery 1 may be insufficient to power the AR-HUD system 5. Under such circumstances, the AR-HUD system 5 may experience display instability. Therefore, it is necessary to charge the first battery 1 promptly. When charging the first battery 1, if the charge level of the backup power supply 3 is greater than or equal to the charge threshold, the power controller 4 can control the backup power supply 3 to charge the first battery 1; if the charge level of the backup power supply 3 is less than the charge threshold, but the charge level of the second battery 2 is greater than or equal to the charge threshold, the power controller 4 can control the second battery 2 to charge the first battery.

[0066] It should be noted that, in the case where the first battery 1 is below the power threshold and the power of the backup power supply 3 is greater than or equal to the power threshold, the case where the power of the backup power supply 3 is greater than or equal to the power threshold includes situations where the power of both the backup power supply 3 and the second battery 2 is greater than or equal to the power threshold, and situations where the power of the backup power supply 3 is greater than or equal to the power threshold and the power of the second battery 2 is less than the power threshold. When the power of both the backup power supply 3 and the second battery 2 is greater than or equal to the power threshold, the power controller 4 preferentially selects the backup power supply 3 to charge the first battery 1. Alternatively, the power controller 4 can also charge the first battery through either the backup power supply 3 or the second battery 2.

[0067] It should be noted that the power threshold can be set in advance according to needs, for example, the power threshold can be 20 mAh, 10 mAh, etc.

[0068] In some embodiments, the power levels of the first battery 1, the second battery 2, and the backup power supply 3 may all be less than the power threshold. In this case, the power alarm information can be displayed on the virtual image of the AR-HUD system 5.

[0069] Since the power levels of the first battery 1, the second battery 2, and the backup power supply 3 are all below the power threshold, the power controller 4 cannot charge the first battery 1 through the second battery 2 and the backup power supply 3. Therefore, the AR-HUD system 5 can directly display the power alarm information on the virtual image to remind the driver that the battery is low.

[0070] In some embodiments, the charge of the first battery 1 may be greater than or equal to the charge threshold. In this case, the first battery 1 does not need to be charged by the second battery 2 or the backup power supply 3, and the first battery 1 can directly power the AR-HUD system 5.

[0071] In some embodiments, when the charge of the first battery 1 and the backup power supply 3 may be greater than or equal to the charge threshold, and the charge of the second battery is less than the charge threshold, the power controller 4 can charge the second battery 2 through the backup power supply 3.

[0072] See Figure 1 The backup power source 3 includes wind power 31 and / or solar power 32.

[0073] In some embodiments, the backup power supply 3 can also be other power sources, such as other batteries, etc.

[0074] As an example, when the power level of either wind power source 31 or solar power source 32 is greater than or equal to a power threshold, if charging of the first battery 1 or the second battery 2 is required, the power controller 4 can control at least one of the wind power source 31 and solar power source 32 to charge the first battery 1 or the second battery 2. When only one of the wind power source 31 and solar power source 32 has a power level greater than or equal to the power threshold, and charging of the first battery 1 or the second battery 2 is required, the power controller 4 controls the power source with a power level greater than or equal to the power threshold to charge the first battery 1 or the second battery 2. When the power levels of both wind power source 31 and solar power source 32 are less than the power threshold, it is determined that the power level of the backup power source 3 is less than the threshold, and the first battery 1 or the second battery 2 cannot be charged through the backup power source 3.

[0075] See Figure 1 The wind power source includes a wind generator 311, a wind controller 312, and a wind supercapacitor 313; the wind generator 311 is connected to the wind controller 312, the wind controller 312 is connected to the wind supercapacitor 313, and the wind supercapacitor 313 is connected to the power controller 4.

[0076] As an example, the wind turbine 311 is installed at the rear of the car and generates electricity by the crosswinds generated by the car while it is in motion; the wind controller 312 is used to convert the electricity generated by the wind turbine 311 into electricity that can be stored in the wind supercapacitor 313; the wind supercapacitor 313 is used to store the electricity generated by the wind turbine 311.

[0077] It should be noted that when the power controller 4 controls the wind power to charge the first battery 1 or the second battery 2, it controls the wind supercapacitor 313 to transmit the electricity generated by the wind generator 311 to the first battery 1 or the second battery 2.

[0078] See Figure 1 The solar power source 32 includes a solar panel 321, a photovoltaic controller 322, and a solar supercapacitor 323; the solar panel 321 is connected to the photovoltaic controller 322, the photovoltaic controller 322 is connected to the solar supercapacitor 323, and the solar supercapacitor 323 is connected to the power controller 4.

[0079] As an example, a solar panel 321 is installed on the roof of a car and is used to convert solar energy into electricity; a photovoltaic controller 322 is used to convert the electricity generated by the solar panel 321 under sunlight into electricity that can be stored in a solar supercapacitor 323; the solar supercapacitor 323 is used to store the electricity generated by the solar panel 321 under sunlight.

[0080] It should be noted that when the power controller 4 controls the solar power supply 32 to charge the first battery 1 or the second battery 2, it controls the solar supercapacitor 323 to transmit the electricity generated by the solar panel 321 to the first battery 1 or the second battery 2.

[0081] It should also be noted that the wind power supercapacitor 313 and the solar power supercapacitor 323 are both supercapacitors, a type of power source with special properties that lies between traditional capacitors and batteries. They primarily rely on the electric double layer and redox pseudocapacitance to store electrical energy. However, no chemical reaction occurs during their energy storage process, making it reversible. Since supercapacitors can be repeatedly charged and discharged hundreds of thousands of times, the function of the solar power supercapacitor 323 is to temporarily store the electrical energy generated by the solar panel 321 and processed by the photovoltaic controller 322. The function of the wind power supercapacitor 313 is to temporarily store the electrical energy generated by the wind turbine 311 and processed by the wind power controller 312.

[0082] In some embodiments, when the charge of the first battery 1 is less than the charge threshold, and the solar panel 321 does not receive light and cannot generate enough power, and the wind generator 311 also cannot generate power, the power controller 4 can transfer the power of the second battery 2 to the built-in first battery 1 when the charge of the second battery 2 is greater than or equal to the charge threshold, so as to power the AR-HUD system through the first battery 1.

[0083] In this embodiment, since the car is equipped with a backup power supply that can charge the first battery, when the first battery's charge is insufficient to support the car's AR-HUD system, the backup power supply can charge the first battery, thereby ensuring that the first battery meets the power requirements for powering the AR-HUD system. This improves the situation where the AR-HUD system's display status is unstable due to low battery, thereby enhancing driving safety and comfort.

[0084] Figure 2 This is a flowchart of a power supply method for an AR-HUD system provided in an embodiment of this application. The power supply method for the AR-HUD system may include the following steps:

[0085] Step 201: Obtain the power status of the first battery, the second battery, and the backup power supply in the vehicle. The first battery is a battery that powers the augmented reality head-up display (AR-HUD) system in the vehicle. The second battery powers the electrical appliances in the vehicle. The backup power supply is used to charge the first battery and the second battery.

[0086] Step 202: When the first battery is below the power threshold, process the first battery according to the power status of the second battery and the backup power supply.

[0087] Step 203: After charging the first battery, power the AR-HUD system through the first battery.

[0088] In this embodiment, when the first battery that powers the AR-HUD system is low, the first battery can be charged according to the power status of the backup power supply and the second battery that powers the electrical appliances in the vehicle. This allows the first battery to meet the power requirements for powering the AR-HUD system, improving the situation where the AR-HUD system's display status is unstable due to low power, thereby enhancing driving safety and comfort.

[0089] In some embodiments, when the first battery is below a power threshold, the first battery is processed according to the power status of the second battery and the backup power supply, including:

[0090] When the charge of the first battery is less than the charge threshold and the charge of the backup power supply is greater than or equal to the charge threshold, the backup power supply is controlled to charge the first battery.

[0091] When the power of the first battery and the power of the backup power source are less than the power threshold, and the power of the second battery is greater than or equal to the power threshold, the second battery is controlled to charge the first battery.

[0092] In some embodiments, after obtaining the state of charge of the first battery, the second battery, and the backup power supply in the vehicle, the method further includes:

[0093] When the power levels of the first battery, the second battery, and the backup power supply are all below the power threshold, a power alarm message is displayed on the virtual image of the AR-HUD system.

[0094] In some embodiments, after obtaining the state of charge of the first battery, the second battery, and the backup power supply in the vehicle, the method further includes:

[0095] When the charge of the first battery and the backup power supply is greater than or equal to the charge threshold, and the charge of the second battery is less than the charge threshold, the second battery is charged through the backup power supply.

[0096] All of the above-mentioned optional technical solutions can be combined in any way to form optional embodiments of this application, and the embodiments of this application will not be described in detail one by one.

[0097] Figure 3 This is a flowchart illustrating a power supply method for an AR-HUD system provided in this application embodiment. This embodiment uses the application of this AR-HUD system's power supply method in a vehicle as an example for illustration. The power supply method for the AR-HUD system may include the following steps:

[0098] Step 301: The vehicle obtains the power status of the first battery, the second battery, and the backup power supply.

[0099] It should be noted that the first battery is dedicated to powering the AR-HUD system in the car, while the second battery powers the car's electrical appliances. A backup power supply is used to charge both batteries. In other words, the first battery is the AR-HUD system's built-in battery, specifically for powering the AR-HUD system, while the second battery powers all other electrical appliances in the car besides the AR-HUD system.

[0100] Since the first battery powers the AR-HUD system in the car, a low battery level can affect the virtual image display. Therefore, the car needs to monitor the first battery's charge level. The second battery powers the car's electrical systems, and a backup power supply can charge both the first and second batteries. Therefore, the car also needs to monitor both the second battery and the backup power supply.

[0101] As an example, the vehicle can monitor and acquire the power status of the first battery, the second battery, and the backup power source in real time, at specified time intervals, upon receiving an acquisition command, after starting the vehicle, and after the AR-HUD system is activated.

[0102] It should be noted that this specified time interval can be preset according to requirements, such as 1 hour, 3 hours, 6 hours, etc. The command to acquire can be triggered when the driver performs a specified operation on the car's virtual or hardware switch, such as a click, swipe, toggle, press, or voice command.

[0103] In some embodiments, the charge status of the first battery, the second battery, and the backup power source obtained by the vehicle can include various situations, such as: the charge of the first battery, the second battery, and the backup power source is all less than a charge threshold; or, the charge of the first battery is less than the charge threshold and the charge of the second battery and the backup power source is greater than or equal to the charge threshold; or, the charge of the first battery and the second battery is less than the charge threshold and the charge of the backup power source is greater than or equal to the charge threshold; or, the charge of the first battery and the backup power source is less than the charge threshold and the charge of the second battery is greater than or equal to the charge threshold; or, the charge of the first battery, the second battery, and the backup power source is greater than or equal to the charge threshold; or, the charge of the first battery and the second battery is greater than or equal to the charge threshold and the charge of the backup power source is less than the charge threshold; or, the charge of the first battery and the backup power source is greater than or equal to the charge threshold and the charge of the second battery is less than the charge threshold, etc.

[0104] It should be noted that the power threshold can be set in advance according to needs, for example, the power threshold can be 20 mAh, 10 mAh, etc.

[0105] In some embodiments, the way the vehicle supplies power varies depending on the charge status of the first battery, the second battery, and the backup power supply.

[0106] As an example, the AR-HUD system is powered by the first battery when the battery charge is greater than or equal to a charge threshold.

[0107] Since the first battery is a dedicated battery for powering the AR-HUD system in the car, it can power the AR-HUD system as long as it has sufficient charge.

[0108] As an example, when the charge of the first battery and the backup power supply is greater than or equal to the charge threshold, and the charge of the second battery is less than the charge threshold, the second battery is charged through the backup power supply.

[0109] Since the first battery can power the AR-HUD system when its charge is greater than or equal to the charge threshold, and the first battery does not require backup power, the backup power will charge the second battery when the backup power is sufficient and the charge of the second battery is less than the charge threshold.

[0110] It is worth noting that when the power of the second battery is less than the power threshold and the power of the backup power supply is greater than or equal to the power threshold, the backup power supply charges the second battery without needing to charge the first battery, thus maximizing resource utilization and saving the vehicle's electrical energy.

[0111] In some embodiments, when the charge of the first battery is greater than or equal to a charge threshold, and the charges of the second battery and the backup power supply are both less than the charge threshold, the first battery AR-HUD system supplies power, and the first battery does not charge the second battery and the backup power supply.

[0112] In some embodiments, when the charge levels of both the first battery and the second battery are greater than or equal to a charge threshold, and the charge level of the backup power supply is less than the charge threshold, the first battery supplies power to the AR-HUD system, the second battery supplies power to other electrical appliances in the vehicle, and neither the first battery nor the second battery charges the backup power supply.

[0113] In some embodiments, when the first battery is below a power threshold, it indicates that the first battery cannot power the vehicle's AR-HUD system with its own power. In this case, the vehicle can perform the operation of step 302 below.

[0114] Step 302: When the first battery is below the power threshold, the vehicle processes the first battery according to the power status of the second battery and the backup power supply.

[0115] Since the vehicle's handling of the first battery depends on the charge levels of the second battery and the backup power supply when the first battery is below the charge threshold, the vehicle needs to handle the first battery according to the charge levels of the second battery and the vehicle's backup power supply.

[0116] As an example, when the first battery's charge level is below a threshold, the vehicle's operation of processing the first battery based on the charge levels of the second battery and the backup power supply includes: when the first battery's charge level is below the threshold and the backup power supply's charge level is greater than or equal to the threshold, controlling the backup power supply to charge the first battery; and when both the first battery's charge level and the backup power supply's charge level are below the threshold, and the second battery's charge level is greater than or equal to the threshold, controlling the second battery to charge the first battery.

[0117] When the power of the first battery is less than the power threshold, it means that the power of the first battery may not be sufficient to power the AR-HUD system. Under such circumstances, the AR-HUD system may experience display instability. Therefore, it is necessary to charge the first battery in a timely manner.

[0118] It should be noted that, in the scenario where the first battery's charge level is below the threshold and the backup power supply's charge level is greater than or equal to the threshold, the scenario where the backup power supply's charge level is greater than or equal to the threshold includes situations where both the backup power supply and the second battery's charge levels are greater than or equal to the threshold, and situations where the backup power supply's charge level is greater than or equal to the threshold, but the second battery's charge level is less than the threshold. When both the backup power supply and the second battery's charge levels are greater than or equal to the threshold, the vehicle can preferentially select the backup power supply to charge the first battery; alternatively, the vehicle can also charge the first battery through either the backup power supply or the second battery.

[0119] In some embodiments, when the charge levels of both the first and second batteries are less than a charge threshold, and the charge level of the backup power supply is greater than or equal to the charge threshold, the backup power supply can continue to charge the second battery after charging the first battery. If the charge level of the backup power supply is still greater than the charge threshold and the charge level of the second battery is less than the charge threshold, the backup power supply can continue to charge the second battery.

[0120] As an example, when the power levels of the first battery, the second battery, and the backup power supply are all below a power threshold, a power alarm message is displayed on the virtual image of the AR-HUD system.

[0121] When the levels of the first battery, the second battery, and the backup power supply are all below the power threshold, it indicates that the overall battery level of the vehicle is low and none of the power sources can provide sufficient power. Therefore, the vehicle can display a battery warning message on the virtual image of the AR-HUD system to alert the driver that the battery is low.

[0122] In some embodiments, after the vehicle displays a battery warning message on the virtual image of the AR-HUD system, it can also turn off the vehicle's AR-HUD system after a specified period of time.

[0123] As can be seen from the above, backup power sources include wind power and / or solar power. Wind power sources include wind turbines, wind controllers, and wind supercapacitors. Solar power sources include solar panels, photovoltaic controllers, and solar supercapacitors. Wind supercapacitors and solar supercapacitors are a type of supercapacitor. Therefore, the amount of electricity in backup power sources refers to the amount of electricity in wind supercapacitors and / or solar supercapacitors.

[0124] As an example, when the power output of either the wind power source or the solar power source is greater than or equal to a power threshold, the vehicle can control at least one of the wind power source or the solar power source to charge the first or second battery if charging is required. When only one of the wind power source or the solar power source has a power output greater than or equal to the power threshold, the vehicle can control the power source with a power output greater than or equal to the power threshold to charge the first or second battery. When the power output of both the wind power source and the solar power source is less than the power threshold, it is determined that the power output of the backup power source is less than the threshold, and the first or second battery cannot be charged using the backup power source.

[0125] Step 303: After charging the first battery, the vehicle supplies power to the AR-HUD system through the first battery.

[0126] When the first battery's charge level is below the threshold, it can be charged by the backup power source or the second battery if the backup power source or the second battery has sufficient charge. Therefore, the first battery will not experience a power outage, and the car can still supply power to the AR-HUD system through the first battery.

[0127] In this embodiment, when the first battery, which powers the AR-HUD system, has a low charge, the vehicle can charge the first battery based on the status of the backup power supply and the second battery, which powers the vehicle's electrical appliances. This ensures the first battery meets the power requirements for the AR-HUD system, improving the stability of the AR-HUD system's display due to low battery levels, thereby enhancing driving safety and comfort. Simultaneously, since the backup power supply can also charge the second battery when its charge is low and the first battery does not need to be charged, maximum resource utilization is ensured, saving overall vehicle energy.

[0128] Figure 4 This is a schematic diagram of the power supply device for an AR-HUD system provided in an embodiment of this application. The power supply device for the AR-HUD system can be implemented by software, hardware, or a combination of both. The power supply device for the AR-HUD system may include: an acquisition module 401, a processing module 402, and a power supply module 403.

[0129] The acquisition module 401 is used to acquire the power status of the first battery, the second battery and the backup power supply in the car. The first battery is a battery that supplies power to the augmented reality head-up display (AR-HUD) system in the car. The second battery supplies power to the electrical appliances in the car. The backup power supply is used to charge the first battery and the second battery.

[0130] Processing module 402 is used to process the first battery according to the power status of the second battery and the backup power supply when the first battery is less than the power threshold.

[0131] The power supply module 403 is used to supply power to the AR-HUD system through the first battery after the first battery has been charged.

[0132] In some embodiments, the processing module 402 is used to:

[0133] When the charge of the first battery is less than the charge threshold and the charge of the backup power supply is greater than or equal to the charge threshold, the backup power supply is controlled to charge the first battery.

[0134] When the charge of the first battery and the charge of the backup power supply are less than the charge threshold, and the charge of the second battery is greater than or equal to the charge threshold, the second battery is controlled to charge the first battery.

[0135] In some embodiments, see Figure 5 The device further includes:

[0136] Display module 404 is used to display power alarm information on the virtual image of the AR-HUD system when the power of the first battery, the second battery and the backup power supply are all less than the power threshold.

[0137] In some embodiments, see Figure 6 The device further includes:

[0138] The charging module 405 is used to charge the second battery through the backup power supply when the charge of the first battery and the backup power supply is greater than or equal to the charge threshold, and the charge of the second battery is less than the charge threshold.

[0139] In this embodiment, when the first battery, which powers the AR-HUD system, has a low charge, the vehicle can charge the first battery based on the status of the backup power supply and the second battery, which powers the vehicle's electrical appliances. This ensures the first battery meets the power requirements for the AR-HUD system, improving the stability of the AR-HUD system's display due to low battery levels, thereby enhancing driving safety and comfort. Simultaneously, since the backup power supply can also charge the second battery when its charge is low and the first battery does not need to be charged, maximum resource utilization is ensured, saving overall vehicle energy.
