[0002] With the development of automotive systems, vehicle instrument systems have become increasingly complex, and the functions performed by the instruments have become more and more complicated. The reliability of the instruments themselves has become an issue that cannot be ignored.

[0003] Among common instrument panels, alarm information has the highest priority. Although the instrument panel is a warning device to ensure vehicle safety, it can also malfunction. When an instrument panel malfunctions, there is no system to serve the instrument panel's faulty state, nor is there a backup system to monitor whether the instrument panel is malfunctioning and temporarily take over the original warning function to perform the alarm duties.

[0004] Therefore, a backup alarm solution for vehicles is needed, which can temporarily replace the original instrument system to emit an alarm sound when the original instrument system fails or partially fails to emit an alarm. Summary of the Invention

[0059] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0060] Figure 1 This is a flowchart of a vehicle backup alarm method provided by one or more embodiments of the present invention.

[0061] like Figure 1 The vehicle backup alarm methods shown include:

[0062] Step S1, receiving information from the external system includes fault type information generated by the external system and abnormal status of the external system in processing fault type information;

[0063] Step S2: Based on the information received from the external system, activate the preset alarm sound.

[0064] The above solution achieves the following beneficial technical effects:

[0065] This application receives information from other systems on the filter bus, identifies the operating status of other systems, and identifies abnormal states when systems process and interact with fault data based on the functional relationships between the systems, thereby providing an alarm function for the operating status of other systems.

[0066] This application identifies an abnormal time interval between fault data information and the status information of the warning commands in the fault data by verifying the fault data information and automatically activating a preset alarm sound, thereby assisting in the execution of the warning commands.

[0067] This application identifies commands sent by other systems on the bus and directly outputs preset alarm tones. It can both monitor the abnormal status of other systems and serve as an alarm unit of the warning system, directly executing commands sent by other systems.

[0068] Specifically, the vehicle backup alarm system primarily acquires interactive data from other external systems via a bus. Because it senses external systems through a bus, the source and purpose of the data can be understood from its content. External systems, as opposed to the vehicle backup alarm system, can include the vehicle's main infotainment system and the instrument cluster system.

[0069] For example, under normal circumstances, the vehicle's main system sends fault information to the bus based on the working status of the hardware and software it manages. For instance, if a cooling component under the management of the main system malfunctions, the instrument cluster system will then instruct the instrument cluster screen to display an icon indicating that the cooling component is overheating, based on the malfunction status of the cooling component.

[0070] During this period, issues such as instrument system malfunction or poor communication between the vehicle's main system and the instrument system cannot be ruled out. Based on information from the aforementioned external systems, the vehicle's backup alarm system can provide auxiliary or supplementary alarms.

[0071] For example, although the instrument system is used for alarms, it may also malfunction, so there is a need to have a backup alarm solution for the instrument system.

[0072] Therefore, based on the command sent by the vehicle's main system to display warning information and the feedback information that the instrument system cannot display warning information normally, the backup alarm system can be triggered to output a preset alarm sound.

[0073] In this embodiment, the abnormal state of the external system processing fault information includes instruction information corresponding to the external system fault state:

[0074] Based on instructions sent by the external system and corresponding to the external system's fault status, a preset alarm sound is activated.

[0075] Specifically, for example, if the vehicle's main infotainment system has self-diagnostic capabilities and can obtain feedback information from the instrument cluster system via the bus, indicating an instrument cluster malfunction or an inability to obtain feedback information normally, the main infotainment system can directly switch to sending commands to the backup alarm system. The backup alarm system then temporarily acts as the instrument cluster system or replaces a portion of its functions, sending alarm sounds. In this case, the backup alarm system is equivalent to an alarm unit within the entire warning system or instrument cluster system.

[0076] For example, the vehicle's main infotainment system and instrument cluster system can use network probe technology to detect each other's communication.

[0077] In this embodiment, the abnormal state of the external system processing fault information also includes information related to the abnormality of the warning function in the corresponding fault information:

[0078] Receive alert information about abnormal alert functions based on alert commands sent from external systems;

[0079] Upon receiving a warning message indicating a malfunction, the system will issue a corresponding warning command and activate a preset alarm sound.

[0080] Specifically, although the instrument cluster system receives a warning command from the vehicle's main infotainment system, it detects a fault while executing the warning command to fulfill its warning function. The instrument cluster system then sends a warning message about the abnormal function to the vehicle's backup warning system, which in turn executes the warning command on behalf of the instrument cluster system. The backup warning system monitors the fault information sent by the main system and provides auxiliary backup warnings.

[0081] In this embodiment, the abnormal state of the external system processing fault information also includes:

[0082] The fault information received from the first external system includes warning commands sent by the external system;

[0083] Receive fault information from the second external system, including feedback information from executing warning commands;

[0084] Determine whether the delay in receiving the feedback information of the execution warning command compared to receiving the warning command sent by the external system exceeds a preset delay threshold;

[0085] If the preset delay threshold is exceeded, a preset alarm sound will be activated for the corresponding fault information of the first external system.

[0086] Specifically, the external system can be either the vehicle's main infotainment system or the instrument cluster system; both are external systems relative to the vehicle's backup alarm system. The main infotainment system doesn't simply send out fault information; it also sometimes reports warning information as part of the instrument cluster system. The main infotainment system may also have subsystems similar to the instrument cluster system. The instrument cluster system sometimes doesn't just have screen display, warning, and alarm functions; it can also detect and manage the fault status of other systems, managing and outputting warnings for the summarized fault statuses. Therefore, the first external system can be considered the main infotainment system, and the second external system can be considered the instrument cluster system. For example, the infotainment system sends fault information, including warning commands, to the bus. If the instrument cluster system receives the warning command, it will implement the preset warning functions according to the command, such as displaying a warning icon or sending a warning sound. After executing the warning function, it will send information about executing the warning command to the bus, such as illuminating the control screen display icon or driving other components according to the warning command, leaving "feedback" information on the bus. The backup alarm system can receive both the warning command and the corresponding execution information from the bus.

[0087] Normally, after receiving the alert command data, the backup alarm system quickly receives the corresponding information from the instrument cluster system to execute the alert command. However, it's possible that instrument cluster system resources are being used by other processes, preventing immediate execution of the alert command. Nevertheless, the instrument cluster system should be able to execute alert commands quickly within a preset timeframe. Therefore, the backup alarm system can filter alert commands and corresponding feedback information. Through delay verification, if it detects a prolonged period without receiving feedback for the corresponding alert command, it can issue an alert sound on behalf of the instrument cluster system, ensuring timely execution of the alert command. Simultaneously, it can also alert the instrument cluster system to suspected faults or anomalies in the vehicle's main infotainment system.

[0088] Figure 2 This is a structural diagram of a vehicle backup alarm device provided in one or more embodiments of the present invention.

[0089] like Figure 2 As shown, the vehicle backup alarm device includes: an information receiving module and an alarm module;

[0090] The information receiving module is used to receive information from external systems, including fault-type information generated by external systems and abnormal states in which external systems process fault-type information.

[0091] The alarm module is used to activate a preset alarm sound based on information received from an external system.

[0092] It is worth noting that although this system only discloses the information receiving module and the alarm module, it does not mean that this device is limited to the above-mentioned basic functional modules. On the contrary, what this invention is meant to express is that, based on the above-mentioned basic functional modules, those skilled in the art can add one or more functional modules in combination with the prior art to form an infinite number of embodiments or technical solutions. That is to say, this system is open rather than closed. It cannot be assumed that the scope of protection of the claims of this invention is limited to the above-disclosed basic functional modules just because this embodiment only discloses a few basic functional modules.

[0093] Figure 3 This is a structural diagram of a vehicle backup alarm system provided by one or more embodiments of the present invention.

[0094] like Figure 3 As shown, the vehicle backup alarm system includes: an on-board embedded module, a main system module, and an alarm function module;

[0095] The main system module is used to generate fault data information;

[0096] The alert function module is used to generate status information for alert commands in the execution fault data;

[0097] An in-vehicle embedded module is used to output preset alarm tones;

[0098] The main system module sends fault data information;

[0099] The warning function module receives fault data information, executes the warning commands in the data, and sends the status information of executing the warning commands.

[0100] The vehicle-mounted embedded module receives fault data and status information for executing warning commands.

[0101] The vehicle-mounted embedded module outputs a preset alarm sound based on the abnormal status in the status information of the warning command executed by the warning function module.

[0102] Specifically, the in-vehicle embedded module, comprised of an embedded system, performs tasks such as bus communication, data verification, and data filtering, processing data from the main system module. The main system module can be considered equivalent to the vehicle's infotainment system, while the warning function module can be equivalent to the instrument cluster system. The in-vehicle embedded module can receive information from the infotainment system, instrument cluster system, and various in-vehicle components such as MCUs and SOCs. These components can communicate via the CAN bus or use direct-connection interrupt lines to handle higher-priority tasks.

[0103] The warning function module may include instrument systems, speaker systems, screen systems, and systems embedded in other systems that display and output fault status. The warning function module can, according to instructions from the main system module, provide warning lights, sounds, and image displays.

[0104] In this embodiment, the vehicle-mounted embedded module includes an instrument signal unit module, a functional safety function module, and a backup audio playback unit module:

[0105] Instrument signal unit module, used for data filtering;

[0106] Functional safety function module, used for data validation;

[0107] The backup sound playback unit module is used to play preset alarm sounds.

[0108] The instrument signal unit module filters bus data, selects fault data information and status information of warning commands in the fault data, and sends them to the functional safety function module.

[0109] The functional safety function module receives the status information of the warning command and the fault data information in the execution fault data, and verifies whether the time interval between receiving the two is abnormal.

[0110] If the time interval between the two is abnormal, a command to play a preset alarm tone will be sent.

[0111] The backup sound playback unit module receives the instruction to play a preset alarm sound and plays the preset alarm sound according to the instruction.

[0112] Specifically, the functions of the in-vehicle embedded module can be implemented by an embedded system, such as an MCU or FPGA. The instrument signal unit module, embedded within the embedded system, can be implemented by program or hardware. It is specifically used to filter fault-related information associated with the instrument system, such as warning commands, the instrument the warning command points to, and feedback information from executing the warning command. The functional safety function module, also implemented by program or hardware, is specifically used to verify data, such as verifying whether the feedback information from executing a warning command in fault data is delayed. The functional safety function module has a corresponding clock program that starts counting after receiving a warning command. If no feedback information for executing the corresponding warning command is received within a preset clock cycle, it indicates that the warning command was not successfully executed, and a corresponding preset alarm tone can be sent. The backup sound playback unit module is used to activate the preset alarm tone. This module can be externally played using the buzzer device integrated into the in-vehicle embedded module, and its function of selecting warning tones can be implemented by program or hardware. There are multiple alarm sounds. For example, one sound indicates a delay in the execution of alarm commands corresponding to fault data, while another sound temporarily assists the instrument system in issuing an alarm. Select the appropriate preset alarm sound based on the actual alarm content and format.

[0113] Figure 7 This is a schematic diagram of the structure of a vehicle backup alarm system according to a specific embodiment of the present invention.

[0114] like Figure 7 As shown, the MCU system internally includes functional zones such as an instrument signal unit, a functional safety function, and a backup audio playback unit. This system acquires data from the CAN bus or signals directly from the SOC, such as interrupt signals. The instrument signal unit filters out instrument-related signals or data and sends the data to the functional safety function for verification, ensuring the data is normal. If the data is abnormal, a command is sent, and the backup audio playback unit selects the corresponding sound file to play based on the type of data anomaly. If the playback power of the backup audio playback unit is too low, the existing instrument speaker can be used. Similarly, if the instrument speaker cannot produce sound, the instrument system can directly send a request to the MCU system to have the backup audio playback unit play the sound in place of the instrument system's speaker. The MCU system indirectly acquires data from the SOC system to the instrument system and interactive information from the instrument system back to the SOC via the bus.

[0115] Figure 4 This is a schematic diagram of the process of a vehicle backup alarm system alarming according to a specific embodiment of the present invention.

[0116] like Figure 4 As shown, the MCU system (e.g., a vehicle backup alarm system) directly receives the backup tone activation signal (e.g., a command from the vehicle's main system) from the SOC or CAN bus. The functional safety function identifies the type of alarm tone to be played. When a signal indicating the need to activate the backup tone is detected, an interrupt is provided to the external MCU, which can synchronously activate the backup alarm tone module. This is equivalent to the vehicle backup alarm system directly sending commands to the backup alarm system.

[0117] Figure 5 This is a schematic diagram of the process of a vehicle backup alarm system triggering an alarm based on an abnormal alarm function, according to a specific embodiment of the present invention.

[0118] like Figure 5 As shown, a signal unit is generated on the MCU to receive instrument-related signals; a functional safety function verifies the data from the SOC or CAN backup tone unit to ensure the accuracy of the input backup alarm tone signal; the backup tone is activated, and an interrupt is provided to the outside of the MCU.

[0119] This is equivalent to the instrument system detecting that it cannot execute the warning command and sending a request to the backup alarm system, which then outputs an alarm sound in place of the instrument system.

[0120] Figure 6 This is a schematic diagram illustrating the process of a vehicle backup alarm system that triggers an alarm based on verification fault data, according to a specific embodiment of the present invention.

[0121] like Figure 6 As shown, a signal unit is generated on the MCU to receive instrument-related signals; a functional safety function verifies the data from the screen alarm light unit fault to ensure the accuracy of the output backup alarm sound signal; at the same time, the delay is verified, and when the delay of the alarm light unit (e.g., information fed back from the instrument system) exceeds 50ms, the backup alarm sound unit is started; the backup sound is turned on, and an interrupt is provided to the outside of the MCU.

[0122] This is equivalent to the vehicle backup alarm system detecting the execution of warning commands and checking for excessive delays. If the delay is too long, a backup alarm is triggered.

The operating system can be any one or more computer operating systems that control the electronic device through processes, such as Linux, Unix, Android, iOS, or Windows. Furthermore, in this embodiment of the invention, the electronic device can be a smartphone, tablet computer, or other handheld device, or a desktop computer, portable computer, or other electronic device; there is no particular limitation in this embodiment.

This firmware is provided by the supplier, and different storage media may have the same or different firmware; no limitation is made here.
