Description

Technical Field

[0001] The present application relates to the field of automobile safety technology, for example, to a method, device and system for suppressing automobile functions. Background Art

[0002] Automotive function suppression technology is widely used in various automotive electronic systems, such as engine control systems, braking systems, and steering systems. When a fault occurs in one of these systems, automotive function suppression technology can quickly respond and take appropriate measures to suppress the fault's impact, ensuring vehicle safety and reliability. The core purpose of automotive function suppression technology is to prevent the spread of the fault, mitigate its impact, and maintain vehicle usability with limited functionality as much as possible, allowing the vehicle to continue driving safely or enter a safe state. For example, in the event of an engine control unit (ECU) fault, the vehicle's maximum speed or power can be limited to prevent further damage or danger.

[0003] Related technologies typically use a Function Inhibition Manager (FIM) to provide control mechanisms for software components and their functions. FIM functionality is implemented by manually adding a Function Identifier (FID) to a fault event in the configuration software. The configuration software then generates a dynamic configuration file that traverses the event state, ultimately affecting the FID to achieve function suppression.

[0004] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0005] After a fault event is detected, the vehicle function is suppressed through the function prohibition manager, which is prone to inaccurate assessment and may affect the normal operation of the vehicle.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field. Summary of the Invention

[0007] The embodiments of the present disclosure provide a method, device, and system for suppressing automobile functions to improve the accuracy of automobile function suppression.

[0012] The method, device, and system for suppressing automobile functions provided by the embodiments of the present disclosure can achieve the following technical effects:

[0013] Achieving precise suppression of vehicle functions is one of the core advantages of this technical solution. In the disclosed technical solution, a matrix relationship table of fault event signals and vehicle function suppression signals is first obtained, and multiple fault event input signals are merged to obtain a virtual vector signal; then, based on the matrix relationship table, the actual cumulative value of the vehicle function suppression signal corresponding to the virtual vector signal is obtained, and finally, based on the actual cumulative value, the vehicle function suppression signal group corresponding to the virtual vector signal is output. Through the precise mapping of the matrix relationship table, it is possible to quickly locate the vehicle function associated with each fault event and calculate the actual cumulative value of the corresponding suppression signal, ensuring that only those vehicle functions that are actually affected by the fault will be suppressed without affecting the use of other normal functions.

It should be understood that the terms used in this manner are interchangeable where appropriate to describe the embodiments of the present disclosure herein.

The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0028] Combine Figure 1 As shown, the embodiment of the present disclosure provides a method for suppressing automobile functions, comprising the following steps:

[0029] S101, obtaining a matrix relationship table of fault event signals and vehicle function inhibition signals.

[0030] Optionally, obtaining a matrix relationship table of fault event signals and vehicle function inhibition signals includes: determining an association relationship table between each fault event signal and the vehicle function inhibition signal; and vectorizing multiple association relationship tables to obtain a matrix relationship table.

[0031] In practical applications, a correlation table between fault event signals and vehicle function inhibition signals is constructed. The correlation table lists all possible fault event signals and their corresponding vehicle function inhibition signals that need to be suppressed. For example, Table 1 below shows an exemplary correlation table:

[0032] Table 1. Association table

[0033] Fault event signal Car function inhibition signal 1 Car function inhibition signal 2 Engine temperature is too high Limiting engine power output / Brake system failure Activate Emergency Brake Assist Speed ​​limit Tire pressure is too low Turn on the tire pressure warning light Speed ​​limit

[0034] Combine Figure 5As shown, multiple association tables are represented as vectors to obtain a matrix relationship table. Each association table is converted into a vector, where the fault event signal is one element of the vector and the corresponding vehicle function inhibition signal is another element of the vector. Multiple such vectors are combined to form a matrix, which is a matrix relationship table of the fault event signal and the vehicle function inhibition signal.

[0035] Through precise mapping within the matrix relationship table, the system can quickly and accurately identify fault events and output corresponding vehicle function suppression signals. Furthermore, the matrix relationship table design makes the system easy to expand and modify. Adding new fault events or vehicle function suppression signals requires simply updating the matrix relationship table. This adaptability allows the system to adapt to ever-changing vehicle functions and fault types, enhancing its flexibility and scalability.

[0036] S102 , combining multiple fault event input signals to obtain a virtual vector signal.

[0037] By combining multiple fault event input signals into a virtual vector signal, the complexity of signal processing is simplified.

[0038] S103 , based on the matrix relationship table, obtaining the actual accumulated value of the vehicle function inhibition signal corresponding to the virtual vector signal.

[0039] S104 , outputting a vehicle function inhibition signal group corresponding to the virtual vector signal according to the actual accumulated value.

[0040] The method for inhibiting automobile functions provided by the embodiments of the present disclosure first obtains a matrix relationship table of fault event signals and automobile function inhibition signals, and combines multiple fault event input signals to obtain a virtual vector signal. Then, based on the matrix relationship table, the actual cumulative value of the automobile function inhibition signal corresponding to the virtual vector signal is obtained, and finally the automobile function inhibition signal group corresponding to the virtual vector signal is output according to the actual cumulative value. Through the accurate mapping of the matrix relationship table, the relevant automobile function can be quickly located for each fault event, and the actual cumulative value of the corresponding automobile function inhibition signal is calculated, so that only those automobile functions that are truly affected by the fault are inhibited, without affecting the use of other normal functions. At the same time, since the cumulative value is used to represent the strength of the automobile function inhibition signal, the degree of automobile function inhibition can be flexibly adjusted according to the severity of the fault, realizing more detailed and accurate control. This accurate inhibition method not only helps to avoid unnecessary performance loss, but also maximizes the safety and reliability of the vehicle, providing a more stable and reliable driving experience for the driver. Through accurate automobile function inhibition, measures can be taken in time when the automobile fails, avoiding the expansion of the influence of the fault on the automobile function, which helps to improve driving safety and reliability and reduce accidents and losses caused by faults.

[0041] In some embodiments, combining the multiple fault event input signals to obtain the virtual vector signal comprises: screening out fault event input signals irrelevant to automobile driving safety from the multiple fault event input signals; sorting the screened fault event input signals according to the influence degree on automobile driving safety; and integrating the sorted fault event input signals to obtain the virtual vector signal.

[0042] During the driving of the automobile, the system will receive multiple fault event input signals in real time. In order to improve processing efficiency and accuracy, these fault event input signals need to be screened first to remove those irrelevant to automobile driving safety. For example, some fault signals related to non-critical functions such as entertainment systems and air conditioning systems can be screened out.

[0043] For the remaining fault event input signals related to automobile driving safety, they need to be sorted according to their influence degree on automobile driving safety. The basis for sorting can be the severity, frequency, and potential threat to driving safety of the fault event. By considering these factors comprehensively, the fault event input signals can be prioritized. The sorted fault event input signals are integrated to form a unified virtual vector signal. This virtual vector signal not only contains the information of the fault event, but also reflects its influence degree and priority on automobile driving safety.

[0044] By filtering out fault event input signals unrelated to vehicle driving safety, the system reduces the amount of information it must process, thereby improving fault handling efficiency. Sorting and integrating fault event input signals allows the system to prioritize those with the greatest impact on driving safety. This helps ensure timely action to mitigate or eliminate the impact of fault events on driving safety, thereby improving driving safety.

[0045] In some embodiments, based on a matrix relationship table, an actual cumulative value of a vehicle function inhibition signal corresponding to a virtual vector signal is obtained, including: obtaining a first weight corresponding to the sorting order of each fault event input signal according to the sorting order of the fault event input signal in the virtual vector signal; and based on the matrix relationship table, using the first weight to determine a first actual cumulative value of each vehicle function inhibition signal corresponding to the fault event input signal.

[0046] Here, the first weight is positively correlated with the sorting order of the fault event input signal in the virtual vector signal, that is, the higher the sorting order of the fault event input signal in the virtual vector signal, the greater the first weight corresponding to the sorting order of the fault event input signal, indicating that the fault event has a greater impact on the driving safety of the vehicle and needs to be handled with priority.

[0047] Using the matrix relationship table and the first weight, a first actual accumulated value of the vehicle function inhibition signal corresponding to the fault event input signal is calculated. Specifically, for each vehicle function inhibition signal, the matrix relationship table is searched to find all corresponding fault event input signals, and the vehicle function inhibition signal is weighted and summed based on the first weight of the fault event input signal to obtain the first actual accumulated value of the vehicle function inhibition signal. The first actual accumulated value can be calculated according to the following formula:

[0048] E1=α 11 ×E 11 +α 12 ×E 12 +…+α 1n ×E 1n

[0049] Among them, E1 is the first actual accumulated value, E 11 is the vector value of the vehicle function inhibition signal corresponding to the first fault event input signal, E 12 is the vector value of the vehicle function inhibition signal corresponding to the second fault event input signal, E 1n is the vector value of the vehicle function inhibition signal corresponding to the nth fault event input signal, α 11 is the first weight corresponding to the first fault event input signal, α 12 is the first weight corresponding to the second fault event input signal, α 1na first weight corresponding to the nth fault event input signal.

[0050] In some specific implementations, in combination with Figure 2 As shown in the figure, the method for inhibiting the automobile function comprises the following steps:

[0051] S201, obtaining a matrix relationship table of fault event signals and automobile function inhibition signals.

[0052] S202, screening out fault event input signals irrelevant to automobile driving safety from the plurality of fault event input signals.

[0053] S203, sorting the screened-out fault event input signals according to the influence degree on automobile driving safety.

[0054] S204, integrating the sorted fault event input signals to obtain a virtual vector signal.

[0055] S205, obtaining a first weight corresponding to the sorting order of each fault event input signal according to the sorting order of the fault event input signals in the virtual vector signal.

[0056] S206, determining a first actual cumulative value of each automobile function inhibition signal corresponding to the fault event input signal based on the matrix relationship table and the first weight.

[0057] S207, outputting a group of automobile function inhibition signals corresponding to the virtual vector signal according to the first actual cumulative value.

[0058] If the first actual cumulative value of a certain automobile function inhibition signal exceeds a preset threshold value, it is considered that this automobile function inhibition signal is effective and needs to be output and executed.

[0059] In the embodiments of the present disclosure, by assigning a first weight to the fault event input signal and calculating a first actual cumulative value of the automobile function inhibition signal according to the first weight, it can be ensured that the fault events with the greatest impact on automobile driving safety are given priority. According to the severity and urgency of the fault event, the output of the automobile function inhibition signal is dynamically adjusted, which can adapt to different fault conditions and take corresponding measures to ensure driving safety. At the same time, by giving priority to the fault events with greater impact on driving safety, the limited resources (such as processor computing power, communication bandwidth, etc.) of the automobile can be more effectively utilized, thereby reducing the overall energy consumption and cost of the system.

[0060] In some embodiments, based on a matrix relationship table, an actual accumulated value of a vehicle function inhibition signal corresponding to a virtual vector signal is obtained, including: obtaining a second weight corresponding to each fault event input signal; based on the matrix relationship table, determining a second actual accumulated value of each vehicle function inhibition signal corresponding to the fault event input signal based on the second weight.

[0061] For each fault event input signal, a second weight is assigned based on factors such as its severity, impact on driving safety, and urgency of repair. The second weight reflects the importance of the fault event in the current situation.

[0062] The second actual accumulated value of the vehicle function inhibition signal corresponding to each fault event is calculated using the matrix relationship table and the second weight of the fault event input signal. Specifically, for each fault event input signal, the matrix relationship table is searched to find all corresponding fault event input signals. The vehicle function inhibition signal is then weighted and summed based on the second weight of the fault event input signal to obtain the second actual accumulated value of the vehicle function inhibition signal. The second actual accumulated value can be calculated using the following formula:

[0063] E2=α 21 ×E 21 +α 22 ×E 22 +…+α 2n ×E 2n

[0064] Among them, E2 is the second actual accumulated value, E 21 is the vector value of the vehicle function inhibition signal corresponding to the first fault event input signal, E 22 is the vector value of the vehicle function inhibition signal corresponding to the second fault event input signal, e 2n is the vector value of the vehicle function inhibition signal corresponding to the nth fault event input signal, α 21 is the second weight corresponding to the first fault event input signal, α 22 is the second weight corresponding to the second fault event input signal, α 2n is the second weight corresponding to the nth fault event input signal.

[0065] In some specific implementations, combined with Figure 3 As shown, the method for suppressing a vehicle function comprises the following steps:

[0066] S301: Obtain a matrix relationship table of fault event signals and vehicle function inhibition signals.

[0067] S302 , combining multiple fault event input signals to obtain a virtual vector signal.

[0068] S303, obtaining a second weight corresponding to each fault event input signal.

[0069] S304, determining, based on the matrix relationship table, a second actual cumulative value of each automobile function inhibition signal corresponding to the fault event input signal based on the second weight.

[0070] S305, outputting the automobile function inhibition signal group corresponding to the virtual vector signal according to the second actual cumulative value.

[0071] If the second actual cumulative value of a certain automobile function inhibition signal exceeds a preset threshold value, it is considered that this automobile function inhibition signal is effective and needs to be output and executed.

[0072] In the embodiments of the present disclosure, by assigning a second weight to the fault event input signal and calculating a second actual cumulative value of the automobile function inhibition signal according to the second weight, it can be ensured that the fault events that have the greatest impact on the safety of the automobile are given priority for processing, which helps to reduce the inconvenience and safety hazards caused by faults. Timely fault processing and output of the automobile function inhibition signal can reduce the inconvenience and safety hazards caused by faults, thereby improving the driving experience and satisfaction of the user. At the same time, since the system can dynamically adjust the output of the inhibition signal according to the severity of the fault event, unnecessary performance loss and function limitation can be avoided, further improving the user experience.

[0073] In some embodiments, the actual cumulative value includes an actual sub-cumulative value corresponding to each automobile function inhibition signal. According to the actual cumulative value, the automobile function inhibition signal group corresponding to the virtual vector signal is output, including: determining a first automobile function inhibition signal in which the actual sub-cumulative value of the automobile function inhibition signal is greater than a first cumulative threshold value, taking the first automobile function inhibition signal as the automobile function inhibition signal group and outputting; determining a second automobile function inhibition signal in which the actual sub-cumulative value of the automobile function inhibition signal is less than the first cumulative threshold value and greater than a second cumulative threshold value; obtaining a historical occurrence frequency of the second automobile function inhibition signal; taking a third automobile function inhibition signal in which the historical occurrence frequency of the second automobile function inhibition signal is greater than a preset occurrence frequency threshold value as the automobile function inhibition signal group and outputting; wherein the first cumulative threshold value is greater than the second cumulative threshold value.

[0074] In some specific actual application scenarios, it is assumed that a vehicle has multiple functions, such as ABS (anti-lock braking system), ESP (electronic stability program), TCS (traction control system), etc. These functions need to be inhibited when certain fault events occur to prevent further damage or ensure safety. The method of the embodiments of the present disclosure aims to intelligently decide which automobile functions need to be inhibited by comprehensively considering multiple fault event signals.

[0075] As shown in Table 2 below, a matrix relationship table (first matrix relationship table) is created, which defines the corresponding relationship between different fault event signals and vehicle function inhibition signals. For example:

[0076] Table 2. First matrix relationship table

[0077] Fault event signal ABS suppression ESP suppression TCS inhibition Signal A 1 0 0 Signal B 0 1 0 Signal C 1 1 0 Signal D 0 0 1

[0078] Among them, 1 means that the corresponding car function needs to be suppressed, and 0 means it does not need to be suppressed.

[0079] Assuming that the fault event input signals currently received are signal A and signal C, the merged virtual vector signal is [1, 0, 1, 0] (corresponding to signals A, B, C, D, where B and D are not triggered).

[0080] According to the virtual vector signal [1,0,1,0] and the matrix relationship table, the actual sub-accumulated value of each vehicle function inhibition signal is calculated:

[0081] ABS suppression: 1 (signal A) + 1 (signal C) = 2

[0082] ESP suppression: 0 (signal A) + 1 (signal C) = 1

[0083] TCS suppression: 0 (signal A) + 0 (signal C) = 0

[0084] The first cumulative threshold is set to 2, the second cumulative threshold is set to 1, and the preset occurrence frequency threshold is set to a certain historical statistical value (such as 5 times / 100 hours).

[0085] The actual sub-accumulation value of ABS suppression is 2, which is greater than the first accumulation threshold, so the ABS suppression signal is output immediately.

[0086] The actual sub-accumulation value of ESP suppression is 1, which is less than the first accumulation threshold but greater than the second accumulation threshold. Further checking of its historical occurrence frequency is required.

[0087] Assuming that the historical occurrence frequency of ESP suppression is greater than the preset occurrence frequency threshold, an ESP suppression signal is also output.

[0088] The actual sub-accumulated value of TCS suppression is 0 and is not output.

[0089] By comprehensively considering multiple fault event signals and historical data, it intelligently determines which vehicle functions need to be suppressed, improving decision-making accuracy and flexibility. Furthermore, by setting cumulative thresholds and historical frequency thresholds, it avoids false suppression caused by a single, accidental fault event, improving system stability and reliability.

[0090] In some embodiments, the actual accumulated value further includes an actual total accumulated value corresponding to the vehicle function inhibition signal. Based on the actual accumulated value, a vehicle function inhibition signal group corresponding to the virtual vector signal is output. The vehicle function inhibition method further includes: before determining the first vehicle function inhibition signal or the second vehicle function inhibition signal, determining that the actual total accumulated value is greater than a total accumulated threshold.

[0091] In some specific practical application scenarios, assume that a car is equipped with four main functions: ABS (anti-lock braking system), ESP (electronic stability program), TCS (traction control system) and ASR (anti-skid system), and these functions may need to be suppressed when certain fault events occur.

[0092] As shown in Table 3 below, a matrix relationship table (second matrix relationship table) is created, which defines the corresponding relationship between different fault event signals and vehicle function inhibition signals. For example:

[0093] Table 3. Second matrix relationship table

[0094] Fault event signal ABS suppression ESP suppression TCS inhibition ASR suppression Signal A 1 0 0 0 Signal B 0 1 0 0 Signal C 1 1 0 0 Signal D 0 0 1 0 Signal E 0 0 0 1

[0095] Assume that the fault event input signals currently received are signal A, signal C, and signal D.

[0096] Calculate the actual sub-accumulated value:

[0097] ABS suppression: signal A(1) + signal C(1) = 2

[0098] ESP suppression: signal B(0)+signal C(1)=1

[0099] TCS suppression: signal D(1) = 1

[0100] ASR suppression: signal E(0) = 0

[0101] Actual total accumulated value = ABS suppression (2) + ESP suppression (1) + TCS suppression (1) + ASR suppression (0) = 4. Assuming the total accumulated threshold is 3, since the actual total accumulated value (4) is greater than the total accumulated threshold (3), the next step of judgment is entered.

[0102] The actual sub-accumulated value (2) of ABS suppression is greater than the first cumulative threshold (assuming it is 2), so an ABS suppression signal is output. The actual sub-accumulated values ​​of ESP suppression and TCS suppression (respectively 1) are less than the first cumulative threshold (2) but greater than the second cumulative threshold (assuming it is 0). The historical occurrence frequencies of ESP suppression and TCS suppression are queried. If the historical occurrence frequency of ESP suppression is greater than a preset occurrence frequency threshold (e.g., 10 times / month), an ESP suppression signal is output. If the historical occurrence frequency of TCS suppression is also greater than the preset occurrence frequency threshold, a TCS suppression signal is output. The final output vehicle function suppression signal group is: ABS suppression, ESP suppression, and TCS suppression.

[0103] By introducing the actual total accumulated value judgment step, a more comprehensive assessment of the impact of the current fault event on vehicle functions can be made. When the actual total accumulated value exceeds a certain threshold, it means that multiple functions may be affected simultaneously. At this time, more careful decisions must be made on which functions to suppress to ensure driving safety and system stability.

[0104] In some specific implementations, combined with Figure 4 As shown, the method for suppressing a vehicle function comprises the following steps:

[0105] S401: Obtain a matrix relationship table of fault event signals and vehicle function inhibition signals.

[0106] S402 , combining multiple fault event input signals to obtain a virtual vector signal.

[0107] S403 : Based on the matrix relationship table, obtain the actual accumulated value of the vehicle function inhibition signal corresponding to the virtual vector signal.

[0108] S404 , determining an actual total accumulated value and an actual sub-accumulated value corresponding to the vehicle function inhibition signal in the actual accumulated value.

[0109] S405: Determine whether the actual total accumulated value is greater than the total accumulated threshold.

[0110] S406 : When the actual total accumulated value is greater than the total accumulated threshold, determine a first vehicle function inhibition signal in which the actual sub-accumulated value in the vehicle function inhibition signal is greater than the first accumulated threshold.

[0111] S407: Output the first vehicle function inhibition signal as a vehicle function inhibition signal group.

[0112] S408 : When the actual total accumulated value is greater than the total accumulated threshold, determine a second vehicle function inhibition signal in which the actual sub-accumulated value in the vehicle function inhibition signal is less than the first accumulated threshold and greater than the second accumulated threshold.

[0113] S409: Obtain a historical occurrence frequency of the second vehicle function inhibition signal.

[0114] S410 , taking the third vehicle function inhibition signal in the second vehicle function inhibition signal whose historical occurrence frequency is greater than a preset occurrence frequency threshold as a vehicle function inhibition signal group and outputting the group.

[0115] In the disclosed embodiment, an actual total cumulative value judgment step is introduced. When multiple fault events occur simultaneously, the degree of their impact on the vehicle's functions can be comprehensively assessed. Only when the actual total cumulative value exceeds the set threshold is the suppression of specific functions further considered, thereby avoiding system overreaction caused by individual fault events. At the same time, combined with the judgment of the actual sub-accumulated values, the vehicle functions that need to be suppressed can be more accurately identified, avoiding functional failures or safety hazards caused by misjudgments. By intelligently determining which functions need to be suppressed, the normal operation of the vehicle can be maintained to the greatest extent possible, reducing the inconvenience caused by function suppression.

[0116] Combine Figure 6 As shown, an embodiment of the present disclosure provides a device for suppressing automobile functions, including a calibration module 601, an input signal module 602, a table lookup module 603, an accumulation module 604 and an output signal module 605, wherein: the calibration module 601 is configured to obtain a matrix relationship table of fault event signals and automobile function suppression signals; the input signal module 602 is configured to merge multiple fault event input signals to obtain a virtual vector signal; the table lookup module 603 is connected to the calibration module 601 and the table lookup module 602, and is configured to determine the automobile function suppression signal corresponding to the virtual vector signal based on the matrix relationship table; the accumulation module 604 is connected to the table lookup module 603, and is configured to obtain the accumulated value of the automobile function suppression signal corresponding to the virtual vector signal; the output signal module 605 is connected to the accumulation module 604, and is configured to output the automobile function suppression signal group corresponding to the virtual vector signal according to the accumulated value.

[0117] In practical applications, combined with Figure 7As shown, the suppression device for automobile functions is implemented based on a Simulink model. The calibration module 601 uses the Constant module from the Simulink built-in library model, and data conversion is achieved through the Data Type Conversion module uont16 from the Simulink built-in library model.

Signal links are connected between the modules using lines according to the directions and ports shown in the diagram.

[0118] By using the Simulink model and subsequently generating C code, the parameter calibration quantity can be changed through the corresponding tool chain or calibration data to achieve diversified requirements.

[0123] The inhibition device for the automobile function first obtains a matrix relationship table of the fault event signal and the automobile function inhibition signal, and combines multiple fault event input signals to obtain a virtual vector signal; then, based on the matrix relationship table, an actual cumulative value of the automobile function inhibition signal corresponding to the virtual vector signal is obtained, and finally, according to the actual cumulative value, a group of automobile function inhibition signals corresponding to the virtual vector signal is output. Through the accurate mapping of the matrix relationship table, for each fault event, the automobile function associated therewith can be quickly located, and the actual cumulative value of the corresponding automobile function inhibition signal can be calculated, so that only those automobile functions that are truly affected by the fault are inhibited, without affecting the use of other normal functions. At the same time, since the cumulative value is used to represent the strength of the automobile function inhibition signal, the degree of automobile function inhibition can be flexibly adjusted according to the severity of the fault, so that more detailed and accurate control is realized. Through accurate automobile function inhibition, measures can be taken in time when the automobile fails, so as to avoid the expansion of the influence of the fault on the automobile function, which helps to improve the driving safety and reliability, and reduce accidents and losses caused by the fault.
