Description

Security icon control method, system, electronic device and storage medium Technical Field

[0001] The present invention relates to the field of vehicle technology, and in particular to a safety icon control method, system, electronic equipment, storage medium and vehicle. Background Art

[0002] Currently, the primary function of warning lights (audio / icon-based information) in traditional automotive instrument clusters is to alert users to vehicle component failures, such as brake system failures and abnormal tire pressure. These warning lights alert users to abnormal operating conditions and present driving risks. However, with technological advancements and rising safety awareness, functional safety-focused design is increasingly being applied to automotive development. Traditional instrument cluster warning lights are no longer able to meet these requirements.

[0003] Patent document CN116700224A discloses a method and apparatus for detecting functional safety mechanism failures in a vehicle. The method comprises: detecting the current operating stage of a microprocessor; if the current operating stage is the initialization monitoring stage, performing a BIST check on the microprocessor; and if the check result indicates a microprocessor failure, verifying the check result using a preset failure reconfirmation strategy, and obtaining microprocessor fault information based on the check result; interrupting the current operating process of the microprocessor based on the fault information, identifying the current fault type of the microprocessor, and matching a corresponding fault handling strategy based on the current fault type to execute the fault handling strategy on the microprocessor. Embodiments of the present application can differentially monitor the operating stage of the microprocessor and match corresponding fault handling strategies to reduce the risk of power interruption during vehicle operation and improve vehicle driving safety.

[0004] In the above-mentioned patent documents and existing technologies, the system fault monitoring capability is low and no clear prompts are given to users.

[0062] 1 , a security icon control method includes:

[0063] S101, in response to a vehicle start signal, obtaining the vehicle CAN bus information based on a defined safety control module, wherein the safety control module is further configured to identify the CAN bus information;

[0064] It can be understood that the safety control module can be a body control system in a vehicle. In this step, the definition of the safety control module is improved accordingly.

[0065] In some embodiments, in order to implement the safety icon control method, the safety control module includes a CSC control module; the CSC control module includes a SOC chip and an MCU control unit, and the SOC chip is communicatively connected to the MCU control unit; the safety icon is displayed on the MFD display module; the SOC chip and the MCU control unit are respectively communicatively connected to the MFD;

[0066] It can be understood that the safety control module in this embodiment includes a CSC (cockpit domain controller) control module, which includes an SOC chip and an MCU control unit. The defined content includes establishing a communication relationship between the SOC chip and the MCU control unit, and establishing a communication relationship between the SOC chip and the MCU control unit and the MFD (vehicle instrument screen module) display module respectively.

[0067] In some applications, in order to obtain CAN bus information in a targeted manner, in response to a vehicle start signal, based on a defined safety control module, the vehicle CAN bus information is obtained. Based on the CSC control module, a communication relationship between the SOC chip and the MCU control unit and the vehicle CAN bus is established; based on the communication relationship, the SOC chip and the MCU control unit synchronously identify and obtain the CAN bus information; the SOC chip and the MCU control unit synchronously obtain the CAN bus information through the identification information of the CSC control module;

[0068] It can be understood that in this application, the SOC chip and MCU control unit in the CSC control module are respectively connected to the CAN bus for communication, and the SOC chip and MCU control unit synchronously obtain the identification information related to the CAN bus information of the CSC control module, that is, the identification information.

[0069] S102, analyzing and processing the CAN bus information based on the safety control module to generate functional safety information;

[0070] It can be understood that in this step, by analyzing and processing the CAN bus information, the type of functional safety information can be analyzed.

[0071] In some applications, in order to accurately generate functional safety information and facilitate the analysis of related faults, the CAN bus information is analyzed and processed based on the safety control module. In generating functional safety information, the CAN bus information synchronously obtained by the SOC chip and the MCU control unit is analyzed and processed based on the safety function information contained in the CSC control module. When the CAN bus information contains content that triggers safety function information, functional safety information is generated based on the triggering content. Functional safety information includes information related to hardware faults in the CSC control module.

[0072] It can be understood that in this application, the safety function information contained in the CSC control module is obtained, such as information related to hardware faults in the CSC control module or the corresponding safety functions contained therein, such as safety function information such as the vehicle body stability system, and it is determined whether the CAN bus information synchronously obtained by the SOC chip and the MCU control unit triggers the above-mentioned safety function information. When the safety function information is triggered, functional safety information is generated based on the triggering content.

[0073] S103, performing verification analysis on the functional safety information based on a preset safety verification algorithm, and generating corresponding safety display information;

[0074] It is understandable that a safety verification algorithm is pre-set in this step, and the algorithm is used to parse the generated functional safety information to generate corresponding safety display information.

[0075] In some applications, to ensure data security and accurate generation of safety display information, functional safety information is verified and analyzed based on a preset safety verification algorithm. When generating corresponding safety display information, the functional safety information generated synchronously by the SOC chip and the MCU control unit carries E2E verification information. The SOC chip and the MCU control unit have preset CRC verification algorithms. When the SOC chip and the MCU control unit generate functional safety information, the functional safety information is verified using the CRC verification algorithm, and corresponding safety display information is generated based on the verification results.

[0076] It can be understood that in this application, the preset verification algorithm includes a CRC verification algorithm. The functional safety information synchronously generated by the SOC chip and the MCU control unit carries E2E verification information. The generated functional safety information is verified and analyzed through the CRC verification algorithm, thereby analyzing and generating corresponding safety display information.

[0077] S104, generating a corresponding security icon based on the security display information, and controlling the security icon to be displayed;

[0078] Among them, the safety control module includes a chip and a micro control unit. The chip and the micro control unit synchronously obtain the CAN bus information. The micro control unit is also used to detect the chip and control the display of the safety icon accordingly based on the detection result.

[0079] It can be understood that in this step, the chip and the micro control unit respectively analyze and process the acquired CAN bus information. In order to ensure that the safety icon can be displayed smoothly, when the chip fails, the micro control unit can control the safety icon to be displayed accordingly.

[0080] In some applications, in order to successfully display the safety icon when encountering an emergency, the corresponding safety icon is generated based on the safety display information. When controlling the display of the safety icon, the SOC chip and the MCU control unit communicate via the SPI interface; the SOC chip and the MCU control unit communicate with the MFD display module via the IIC interface respectively; based on the IIC interface, the SOC chip controls the display of the safety display icon on the MFD display module; based on the SPI interface, the SOC chip periodically sends its own operating status message to the MCU control unit at a preset detection time; when the MCU control unit detects a fault in the SOC chip, based on the IIC interface, the MCU control unit controls the display of the safety display image on the MFD display module;

[0081] It can be understood that in this application, in the defined safety control module, a communication relationship is established between the SOC chip and the MCU control unit, and the communication relationship is established through the SPI (Serial Peripheral Interface) interface. The communication relationship is used to detect the SOC chip through the MCU control unit. For example, the SOC chip periodically sends its own operating status message to the MCU control unit. The period can be 100ms. When the SOC chip fails, the safety icon is controlled to be displayed on the MFD display module through the communication relationship between the defined MCU control unit and the MFD display module through the IIC interface. When the SOC chip is not faulty, the safety icon is controlled to be displayed on the MFD display module through the communication relationship between the SOC chip and the MFD display module through the IIC interface.

[0082] Through the above steps, the system fault monitoring capability can be improved. When a hazardous event occurs, the user can still be given a prominent prompt to inform the user whether the current vehicle is at risk, thereby reducing the probability of personal injury to the driver.

[0083] The following describes embodiments of the security icon control method of the present invention in some applications with reference to FIG. 2 to FIG. 6 :

[0084] As shown in Figure 2, conventional automotive instrument cluster modules (MFDs) often utilize IIC communication. In existing cockpit domain controller (CSC) designs, MFD displays are implemented through information exchange with the CSC's underlying SOC chip. Display content is similar to traditional instrument clusters, providing the driver with information such as vehicle faults, component operating status, and multimedia information. In this solution, there is no information exchange between the CSC's MCU and the MFD.

[0085] This architecture has two disadvantages: 1. If the SOC function fails and cannot send a message to the display, the driver will not be able to determine whether the vehicle has a fault, posing a risk to their own safety; 2. This traditional solution only indicates functional failures of the component itself, lacks ASIL design practices based on functional safety for systematic failures / random hardware failures, and does not provide the driver with warning icons based on functional safety design.

[0086] As shown in Figure 3, in this embodiment, an MCU-based monitoring design is added to improve the hazard event monitoring capability, and a functional safety icon display is added to the instrument screen. When a specified hazard event occurs, the driver is notified of the danger through the icon display, meeting the functional safety requirements and upgrading the original QM-level design to ASILB level.

[0087] As shown in Figures 3 and 4, both the SOC and MCU synchronously obtain functional safety information via the CAN bus. This information carries E2E verification information, and the SOC and MCU have equal parsing and processing capabilities for this information. This verification method verifies the content of the entire CAN message frame. The basic message format can be described as: CANID+DATA0+DATA1+....+DATAN+CRC. At the sending end, the ECU uses the CRC8 calculation function to introduce the data from CANID to DATAN into the formula for calculation. Similarly, after receiving the CAN message, the SOC and MCU use the same algorithm to obtain the message. Only after the verification is passed will the information content be used.

[0088] The CRC algorithm uses the polynomial of the CRC-8-SAE J1850 algorithm, that is, the polynomial value is 0x1D (x8+x4+x3+x2+1).

[0089] As shown in Figures 3 and 5, an IIC communication interface has been added between the MCU and the MFD, enabling the MCU to also control the display of the MFD functional safety icon;

[0090] When the SOC itself is operating normally, it will periodically send icon lighting information to the MPD via the IIC communication interface. In this state, the MCU does not actively send messages to the MPD. When the SOC is operating abnormally, the MCU will send icon lighting information to the MPD via the IIC interface.

[0091] As shown in Figures 3 and 6, a new SPI communication logic is added between the MCU and the SOC. The SOC periodically sends its own operating status message to the MCU (e.g., a 100ms period). The MCU monitors the status. If the operating status sent by the SOC is detected to be abnormal or the SOC message is not received for a long time (e.g., 500ms), the MCU determines that the SOC has failed and cannot send the correct display information to the MPD. In this case, the MCU actively sends a display icon message to the MPD through the IIC communication interface.

[0092] A new functional safety warning message (Function Safety Warning) has been added to the MFD display side; when a hazardous event occurs, a new functional safety icon is used to remind the driver of the current vehicle danger. The MPD obtains the "Enable Functional Safety Icon" signal from the IIC. When the signal value is 1, the MPD will light up the functional safety icon to issue a danger warning to the driver.

[0093] In this embodiment, the functional safety icon display logic is as follows:

[0094] The SOC and MCU synchronously acquire and analyze E2E functional safety information from the CAN bus to determine whether a functional safety failure has occurred. When a failure is detected, the SOC illuminates the functional safety icon on the MFD via IIC communication to provide a safety reminder to the driver. When the SOC is operating normally, the MCU does not send a functional safety icon illumination message to the MFD.

[0095] To prevent the functional safety icon from failing to display due to abnormal SOC operation, the MCU determines the SOC's operating status through SPI communication. If the MCU detects an SOC malfunction or a heartbeat loss, it determines that the SOC is unable to properly illuminate the functional safety icon. In this scenario, the MCU proactively sends a message to the MFD to illuminate the functional safety icon based on the results of the functional safety information analysis, taking over the function of illuminating the functional safety icon.

[0096] For example, while the car is driving, if the driver opens multiple multimedia applications and the SOC suddenly freezes due to long-term heavy load, the SOC will be unable to send alarm information to the display screen (MPD). In this scenario, the MCU finds that it cannot receive the SPI information periodically sent by the SOC, and believes that it has a fault. It actively forwards the icon lighting information to the MPD to ensure that in the event of danger to the vehicle, the driver can perceive the danger from the MPD, thereby achieving the purpose of protecting the driver's safety.

[0097] This embodiment is applicable to a vehicle's intelligent cockpit system. In this solution, the SOC identifies E2E functional safety information and updates the functional safety icon on the display. The MCU monitors the SOC's operating status. If the MCU detects an SOC fault, it proactively updates the status of the functional safety icon on the instrument panel, meeting functional safety requirements.

[0098] For the method steps disclosed in the above embodiments, for the purpose of simple description, the method steps are expressed as a series of action combinations. However, those skilled in the art should be aware that the embodiments of the present invention are not limited by the order of the actions described, because according to the embodiments of the present invention, certain steps can be performed in other orders or simultaneously.
