Description

Technical Field

[0001] This invention belongs to the field of vehicle control technology, and specifically provides a vehicle-mounted equipment control method, computer equipment, storage medium, and vehicle. Background Technology

[0002] Energy replenishment solutions for new energy electric vehicles mainly include two modes: vehicle charging and battery swapping. Compared to vehicle charging, battery swapping allows for quicker battery replacement, enabling users to swap and go immediately. This significantly improves the problem of long waiting times for energy replenishment in new energy electric vehicles, saving users time.

[0003] Currently, when a vehicle arrives at a battery swapping station, all occupants are typically required to exit the vehicle. Station staff then drive the vehicle into the swapping bay, complete the swap, and return the vehicle to the driver. With technological advancements, the safety of the swapping process has improved, and on-board battery swapping, where occupants do not need to leave the vehicle, is becoming increasingly common at swapping stations. However, during the swapping process, most vehicle equipment becomes unusable, leading to increased boredom and frustration, especially in hot or cold weather. Therefore, how to ensure users can continue using some comfort-oriented in-vehicle equipment (such as air conditioning and seat heating) and / or entertainment-oriented equipment (such as in-vehicle displays and audio systems), and stay informed about the swapping progress, while allowing the low-voltage battery to maintain a comfortable environment and alleviate the boredom of waiting, has become a pressing issue.

[0004] Accordingly, a new solution is needed in this field to address the aforementioned problems. Summary of the Invention

[0014] Always enable the first priority device.

[0015] In one embodiment of the above-mentioned vehicle-mounted equipment control method, "controlling the vehicle-mounted equipment according to the low-voltage battery charge and the preset vehicle-mounted equipment priority" further includes:

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0039] First read Figure 1 , Figure 1 This is a flowchart illustrating the main steps of the vehicle-mounted equipment control method according to an embodiment of the present invention. Figure 1 As shown, the vehicle-mounted equipment control method of the present invention includes:

[0040] Step S101: Obtain the low-voltage battery power of the low-voltage power supply module;

[0041] Step S102: Control the vehicle equipment according to the low-voltage battery power and the preset vehicle equipment priority.

[0042] After a new energy electric vehicle enters the battery swapping station, the vehicle central controller (VCC) and the station controller (PES) are connected via Wi-Fi, Bluetooth or other wireless communication methods, and the vehicle enters the battery swapping mode.

[0043] The battery swapping process mainly includes: vehicle certification, vehicle preparation, battery swapping preparation, high-voltage battery swapping, vehicle self-inspection, and high-voltage power-on.

[0044] Typically, during the battery swapping preparation phase, the vehicle's central controller controls the high-voltage battery management module (BMS) to enter a single-point sleep state, shutting off the high-voltage power supply to meet the needs of battery insertion and removal operations during battery swapping, thereby ensuring the safety of personnel and equipment.

[0045] Furthermore, after shutting down all onboard devices (excluding those currently in use by the user and those not of the highest priority) and reducing the low-voltage load, the onboard devices are then powered by the low-voltage battery module (LBM).

[0046] In step S101, the vehicle central controller obtains the low-voltage battery power (e.g., the power of a 12V battery) of the low-voltage power supply module through the vehicle's CAN bus.

[0047] In step S102, the vehicle equipment is controlled based on the low-voltage battery charge obtained in step S101 and the pre-set priority classification of the vehicle equipment. By making reasonable use of the low-voltage battery, users can turn on some comfort and / or entertainment-type vehicle equipment during the battery swapping process, reflecting a human-centered design and improving the user experience.

[0048] In this embodiment of the invention, the priority of in-vehicle devices is set after comprehensively considering factors such as functionality, power consumption, and user usage frequency. For example, functions can be categorized into vehicle control functions, entertainment functions, and comfort functions, with vehicle control devices having a higher priority than entertainment / comfort devices; low-power in-vehicle devices having a higher priority than high-power devices; and frequently used in-vehicle devices having a higher priority than infrequently used devices. Furthermore, users can also set the priority of in-vehicle devices according to their personal preferences.

[0049] Preferably, the priority of on-board equipment includes first-priority equipment, second-priority equipment, and third-priority equipment. The first-priority equipment is mainly vehicle control equipment, specifically including: vehicle central controller, vehicle control unit (VCU), low-voltage battery management module, body control module (BCM), air conditioning controller (ACC), cockpit domain controller (CDC), etc.

[0050] During the low-voltage power supply period, the first-priority devices will always be enabled to ensure network communication between controllers. This allows them to respond promptly to user operations based on instructions from the vehicle's central controller and control the operation of the second-priority and third-priority devices. Simultaneously, it ensures data communication between the vehicle and the battery swapping station, enabling the vehicle's central controller to obtain real-time information on the vehicle's battery swapping progress.

[0051] The second and third priority devices are primarily devices that provide comfort and entertainment functions for drivers and passengers. Users can turn devices on and off, and set device parameters via buttons, knobs, or smart terminals connected to the vehicle. After receiving the user's operation request, the vehicle's central controller can choose to respond to or reject the user's operation request based on the low-voltage battery level, and notify the corresponding vehicle control device in the first priority device, which then controls the corresponding execution device.

[0052] Second-priority equipment includes: seat heating devices, air conditioning fans, and ambient lighting. Third-priority equipment includes: in-vehicle display devices, in-vehicle audio systems, reading lights, and vanity mirror lights.

[0053] Next, combine Figure 2 This section explains the specific implementation process of step S102.

[0054] As an example, the first power threshold is set to 85% of the low-voltage battery capacity, the second power threshold is set to 70% of the low-voltage battery capacity, and the third power threshold is set to 60% of the low-voltage battery capacity. Those skilled in the art can also set appropriate power thresholds based on factors such as the low-voltage battery capacity and the power of the on-board equipment.

[0055] Scenario 1: The low-voltage battery charge is greater than or equal to the first charge threshold. At this time, the low-voltage battery has sufficient charge to provide users with more comfort and / or entertainment services. In this case, it is allowed to respond to the user's activation command for the second priority device and / or the third priority device, and activate one or more of the in-vehicle devices at the same time.

[0056] As an example, a user in the vehicle wants to activate the low-volume air recirculation mode while also watching a short video on the central control screen (in-vehicle display device). After receiving signals from the user operating the relevant switches and knobs of the air conditioning equipment, the vehicle's central controller responds to the user's operation by sending switch signals and fan operating parameters (airflow parameters) to the air conditioning controller via the CAN bus. Upon receiving the relevant instructions, the air conditioning controller controls the operation of the air conditioning fan.

[0057] Furthermore, after receiving the operation signal from the central control screen, the vehicle's central controller also responds to the user's operation by sending a command to the cockpit domain controller via the CAN bus, allowing the cockpit domain controller to control the central control screen to display the short video set by the user.

[0058] Scenario 2: The low-voltage battery power is greater than or equal to the second power threshold and less than the first power threshold. In this case, the low-voltage battery power is still relatively sufficient, and it can continue to allow the user to respond to the second priority device's activation command, while disabling the third priority device.

[0059] As an example, a user in the vehicle wants to activate the low-speed air recirculation mode and watch a short video on the central control screen. In this situation, the vehicle's central controller will not respond to the user's air conditioning operation request, but it can respond to the user's central control screen operation request and play the short video. Furthermore, it can send a notification to the user via the car audio system and / or the central control screen, informing them that the low-voltage battery power is low and the air conditioning fan cannot be turned on.

[0060] Scenario 3: The low-voltage battery power is greater than or equal to the third power threshold and less than the second power threshold. In this case, the low-voltage battery power is slightly insufficient, the third priority device is disabled, and the user's command to activate the second priority device is prohibited. However, the vehicle control system displays vehicle system messages through the in-vehicle display device and / or in-vehicle audio system set in the second priority device.

[0061] As an example, a user in the vehicle wants to activate the low-speed air recirculation mode and watch a short video on the central control screen. In this case, the vehicle's central controller will not respond to the user's requests for air conditioning or central control screen operation. Furthermore, it can send a notification to the user via the car audio system and / or the central control screen, informing them that the low-voltage battery is low and cannot operate the air conditioning fan or play the video.

[0062] Scenario 4: When the low-voltage battery charge is below the third charge threshold, in order to ensure the smooth completion of the battery swapping process and protect the low-voltage battery from damage due to over-discharge, all third-priority and second-priority devices will be disabled, and only the first-priority devices will be allowed to operate. In other words, the third-priority and second-priority devices will not respond to user operation requests, and the vehicle's central controller will no longer display vehicle system messages through the second-priority devices.

[0063] In another embodiment, with the low-voltage battery fully charged, the user turns on the air conditioner fan and watches a video via the central control screen.

[0064] As the user uses the device, the low-voltage battery power decreases. When the low-voltage battery power drops to the first power threshold, the user will be notified that the air conditioner fan (the third priority device) will be automatically turned off due to the low-voltage battery power. The countdown time can also be displayed simultaneously.

[0065] At this point, the user can manually turn off the air conditioning fan, or leave it as is. After the countdown ends, the vehicle's central controller will automatically control the air conditioning controller to turn off the air conditioning fan.

[0066] As the user continues to use the device, the low-voltage battery level continues to decrease. When the low-voltage battery level drops to the second power threshold, a second prompt message is sent to the user, indicating that the video playback function of the central control screen (second priority device) will be automatically turned off due to the further decrease in the low-voltage battery level, and a countdown timer can be displayed simultaneously.

[0067] At this point, the user can manually turn off the central control screen, or leave it as is. After the countdown ends, the vehicle's central controller will automatically control the cabin domain controller to turn off the central control screen.

[0068] In this embodiment of the invention, in order to enable users to understand the battery swapping process in real time, the battery swapping process information can be displayed in different forms through the vehicle display device during the battery swapping waiting process, based on the low-voltage battery power.

[0069] When the low-voltage battery charge is greater than or equal to the second charge threshold, the battery swapping process information can be displayed in an animated manner on the central control screen. This provides a more intuitive and vivid presentation of the battery swapping process, offering users a better interactive experience. For example, it can display the location trajectory of the removed and / or replaced battery, and dynamic battery swapping progress animations.

[0070] When the central control screen displays an animation of the battery swapping process, if the user wants to watch a video on the screen, the user's needs are prioritized, and the user-defined video content is displayed. Simultaneously, the battery swapping process information is displayed as text and / or images in a message box in the corner of the central control screen, instead of being displayed as an animation. Furthermore, the user can drag this message box to their desired location using the touch panel of the central control screen. This method maximizes user consideration, making the method more user-friendly and further enhancing the user's interactive experience and satisfaction.

[0071] When the low-voltage battery charge is greater than or equal to the third charge threshold and less than the second charge threshold, the battery swapping progress information will be displayed in text and / or image format via a message box on the central control screen. Simultaneously, the backlight of the central control screen can be turned off or dimmed to reduce its power consumption and extend the usable time of the low-voltage battery.

[0072] If the central control screen is being used before the low-voltage battery level falls below the second power threshold, such as playing a user-defined video or displaying an animation showing the battery swapping progress, then when the low-voltage battery level equals the second power threshold, the user-defined display content will be automatically turned off, or the animated battery swapping progress information will be turned off. Instead, the battery swapping progress information will be displayed in the form of text and / or images through a message box. This reduces the power consumption of the central control screen, extends the time that users can access battery swapping progress information, and ensures that users can still keep track of the battery swapping progress in a timely manner, thus guaranteeing a good user experience.

[0073] When displaying battery swapping progress information on the central control screen, it can also simultaneously display low-voltage battery level, vehicle and / or battery swapping station alarm information, according to user settings. Furthermore, when displaying alarm information, the corresponding handling measures can be shown simultaneously, providing users with more targeted services and improving the user experience. For example, when the low-voltage battery level drops to a set threshold, the central control screen displays a low-voltage battery level alarm and a prompt to shut down equipment.

[0074] When the low-voltage battery charge is less than the third charge threshold, all second-priority devices will be prohibited from use. This includes the vehicle central controller, which will no longer control the central control screen to display battery swapping progress information, vehicle system messages, etc., through the cockpit domain controller.
