[0024] Embodiment 1
[0025] According to an embodiment of the present disclosure, an embodiment of a risk assessment method for a vehicle function scenario is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in an order different from that shown herein.
[0026] FIG. 1 is a flowchart of an optional risk assessment method for a vehicle function scenario according to an embodiment of the present disclosure, as shown in FIG. 1, the method comprises the following steps:
[0027] Step S102, acquiring the function use case of the intelligent driving function of the vehicle, wherein the function use case is used to represent the conditions that need to be met by the intelligent driving function in different function scenarios.
[0028] The above-mentioned vehicle refers to a vehicle containing intelligent driving function, including but not limited to a car, a truck, a van, a bus, etc. containing intelligent driving function.
[0029] The above-mentioned intelligent driving function is a system that improves driving safety and convenience by using advanced technology. These functions enable vehicles to achieve partial or full automation through the integration of sensors, cameras, radars and other devices, as well as artificial intelligence and machine learning algorithms. In the present disclosure, the intelligent driving function of the vehicle needs to be functional, and the safety of the vehicle when starting the intelligent driving function is ensured by the functional intelligent driving function of the vehicle.
[0030] Table 1
[0031] The above function case refers to the function index of the vehicle intelligent driving function in different function scenarios. The more comprehensive the function case of the vehicle intelligent driving function is, the more comprehensive the function index of the vehicle intelligent driving function in different function scenarios is, so that the intelligent driving function of the vehicle is more effective. The function case of the vehicle intelligent driving function includes but is not limited to: version number of the function case, function case brief, vehicle intelligent driving function requirement description, vehicle mode, function case precondition, function case postcondition, path information, non-functional requirement, and vehicle human-machine interface (HMI) requirement.
[0032] The above function scenario refers to a simulated scenario for the function vehicle intelligent driving function. The function scenario can be set according to the conditions that the vehicle may encounter during intelligent driving. Therefore, for different conditions that the vehicle may encounter during intelligent driving, different function scenarios are set, and the vehicle performs the intelligent driving function in the function scenario to determine whether the vehicle intelligent driving function is perfect.
[0033] In an optional embodiment, the function case of the vehicle intelligent driving function can be artificially designed based on experience and actual situation. For example, Table 1 is a function case table of the automatic driving function of the vehicle driver navigation. The function case of the automatic driving function of the vehicle driver navigation (Navigate on Pilot, NOP) is shown in Table 1.
[0034] As shown in Table 1, the function case of the automatic driving function of the vehicle driver navigation is used to indicate the conditions that need to be met when the automatic driving function of the vehicle driver navigation performs functions in different function scenarios.
[0035] In another optional embodiment, the function case of the vehicle intelligent driving function can also be obtained by software calculation. The function case is used to indicate the conditions that need to be met when the intelligent driving function performs functions in different function scenarios.
[0036] In the present disclosure, by obtaining the function case of the vehicle intelligent driving function, the conditions that need to be met when the vehicle performs functions in different function scenarios are more comprehensive, the comprehensiveness of the vehicle function scenario is improved, and the effectiveness of the vehicle intelligent driving function is improved.
[0037] In step S104, the target behavior of the intelligent driving function in the function case is analyzed to determine at least one function scenario containing the trigger condition corresponding to the target behavior and the vehicle behavior of the vehicle. The vehicle behavior is formed by the influence of the target behavior on the vehicle. The target behavior is used to indicate the behavior that does not meet the corresponding expected standard of the intelligent driving function during use of the intelligent driving function.
[0038] The target behavior refers to a behavior of the vehicle that has an impact on the vehicle and has the potential to cause the vehicle to be dangerous when the vehicle uses the intelligent driving function. When the vehicle uses the intelligent driving function, the vehicle can have a behavior that does not meet the expected standard corresponding to the intelligent driving function. This behavior that does not meet the expected standard corresponding to the intelligent driving function can have an impact on the vehicle and cause the vehicle to be dangerous, and therefore the behavior that does not meet the expected standard corresponding to the intelligent driving function is defined as the target behavior.
[0039] The at least one functional scenario containing the trigger condition corresponding to the target behavior refers to a functional scenario containing the trigger condition triggering the target behavior. When the functional scenario contains the trigger condition of the target behavior, the target behavior can occur in the functional scenario. When the functional scenario does not contain the trigger condition of the target behavior, the target behavior cannot occur in the functional scenario.
[0040] The vehicle behavior refers to a vehicle behavior of the vehicle caused by the impact of the target behavior. Since the target behavior has an impact on the vehicle and has the potential to cause the vehicle to be dangerous, after the vehicle is affected by the target behavior, the vehicle can have behaviors such as overspeeding, being out of control, and greatly decelerating. The vehicle behavior can cause the vehicle to be dangerous.
[0041] In an optional embodiment, the target behavior of the intelligent driving function in the functional use case can be analyzed by hazard and operability study. After determining the target behavior that does not meet the expected standard corresponding to the intelligent driving function, the vehicle behavior that can be caused by the target behavior and at least one functional scenario corresponding to the target behavior are determined by hazard and operability study. Hazard and operability study is a structured and systematic process design and operation analysis method for identifying, evaluating and controlling potential risks in the process. In this disclosure, hazard and operability study is used to analyze potential risks in the functional use case to determine the target behavior of the intelligent driving function in the functional use case.
[0042] In this disclosure, by analyzing the target behavior of the intelligent driving function in the functional use case, at least one functional scenario containing the trigger condition corresponding to the target behavior and the vehicle behavior of the vehicle can be determined. The risk of the functional scenario is evaluated based on the vehicle behavior, and then it is judged whether the functional scenario needs to be adjusted. When the risk of the functional scenario is low, the functional scenario does not need to be adjusted. When the risk of the functional scenario is high, the functional scenario needs to be adjusted. The rationality of the functional scenario is improved, and the accuracy of the intelligent driving function of the vehicle is improved.
[0043] In step S106, the at least one function scene is risk evaluated based on the vehicle behavior to obtain an evaluation result, wherein the evaluation result is used to indicate whether the at least one function scene meets the expected function safety.
[0044] The risk evaluation refers to risk evaluation of the at least one function scene based on whether the vehicle behavior will cause an accident or violate traffic rules, etc., to determine whether the risk factor can be accepted. The expected function safety can be a pre-set risk evaluation standard.
[0045] The evaluation result refers to a result obtained after risk evaluation of the at least one function scene, and the evaluation result is that the function scene meets the expected function safety or the function scene does not meet the expected function safety.
[0046] The expected function safety is a pre-set risk standard used to determine whether the function scene needs to be adjusted. When the function scene meets the expected function safety, it is determined that the risk factor is acceptable. When the function scene does not meet the expected function safety, it is determined that the risk factor is not acceptable.
[0047] In an optional embodiment, the at least one function scene is risk evaluated based on the vehicle behavior to obtain an evaluation result. It is determined whether the at least one function scene meets the expected function safety or the at least one function scene does not meet the expected function safety.
[0048] In the present disclosure, the expected function safety is pre-set, and it is determined whether the at least one function scene meets the expected function safety by risk evaluation of the at least one function scene, so that it is determined whether the function scene meets the expected function safety, and the function scene is adjusted to improve the rationality of the vehicle function scene.
[0049] The function use case of the intelligent driving function of the vehicle is obtained through the above steps; the target behavior of the intelligent driving function in the function use case is analyzed to determine at least one function scene containing a trigger condition corresponding to the target behavior and a vehicle behavior of the vehicle; the at least one function scene is risk evaluated based on the vehicle behavior to obtain an evaluation result; and the vehicle function scene of the vehicle is generated based on the evaluation result and the at least one function scene. The disclosure obtains the function use case to determine the conditions that need to be met by the vehicle intelligent driving function in different scenes to obtain the conditions for the vehicle to perform the function more comprehensively, determines the target behavior of the vehicle that does not meet the expected standard of the intelligent driving function through the function use case, determines the function scene corresponding to the target behavior and the vehicle behavior caused by the influence of the target behavior on the vehicle, and evaluates the risk of the function scene through the vehicle behavior, sets a standard to judge whether the function scene meets the expectation, and generates the vehicle function scene based on the evaluation result and the function scene, so that when the function scene does not meet the expectation, the function scene is adjusted to meet the expectation, so that the vehicle function scene is more reasonable, the comprehensiveness and rationality of the vehicle function scene are improved, thereby realizing the technical effect of improving the accuracy of the vehicle intelligent driving function, and further solving the technical problem of poor safety of vehicle intelligent driving caused by low accuracy of the vehicle intelligent driving function.
[0050] Optionally, the method further comprises: generating a vehicle function scene of the vehicle based on the evaluation result and the at least one function scene.
[0051] The vehicle function scene is an adjusted function scene. After obtaining the evaluation result, it is determined whether the at least one function scene needs to be adjusted based on the evaluation result. If there is a function scene in the at least one function scene that does not meet the expected function safety, the function scene that does not meet the expected function safety is adjusted to obtain an adjusted function scene, i.e., the vehicle function scene. If there is no function scene in the at least one function scene that does not meet the expected function safety, the at least one function scene is the vehicle function scene. The vehicle function scene has higher adaptability and is more comprehensive than the function scene.
[0052] In an optional embodiment, the function scene that does not meet the expected function safety in the at least one function scene is determined through the evaluation result. The target behavior in the function scene that does not meet the expected function safety can be determined in a human-determined manner, and the adjustment requirement of the function scene that does not meet the expected function safety is determined according to the target behavior. The function scene that does not meet the expected function safety is adjusted based on the adjustment requirement to obtain the vehicle function scene. If the evaluation result is that there is no function scene in the at least one function scene that does not meet the expected function safety, the at least one function scene does not need to be adjusted, and the vehicle function scene is directly generated.
[0053] In another optional embodiment, the function scene that does not conform to the expected function safety is determined through the evaluation result, and the target behavior in the function scene that does not conform to the expected function safety is also determined through program calculation, and the adjustment requirement of the function scene that does not conform to the expected function safety is artificially determined according to the target behavior, and the function scene that does not conform to the expected function safety is adjusted based on the adjustment requirement to obtain the vehicle function scene. If the evaluation result is that there is no function scene that does not conform to the expected function safety in the at least one function scene, the at least one function scene does not need to be adjusted, and the vehicle function scene is directly generated.
[0054] In the present disclosure, the function scene that does not conform to the expected function safety is adjusted to obtain the function scene that conforms to the expected function safety after adjustment, so that the accuracy of intelligent driving of the vehicle is improved, and the user experience is effectively improved.
[0055] Optionally, the vehicle function scene of the vehicle is generated based on the evaluation result and the at least one function scene, including: determining a target function scene in the at least one function scene based on the evaluation result, wherein the target function scene is a scene that does not conform to the expected function safety in the at least one function scene; determining a safety requirement condition of the target function scene according to a target behavior in the target function scene, wherein the safety requirement condition is used to represent a condition that needs to be met to cope with the target behavior; adding a threshold parameter associated with the target behavior to the target function scene based on the safety requirement condition to obtain the vehicle function scene.
[0056] The target function scene refers to the function scene that does not conform to the expected function safety, wherein since the target behavior can correspond to multiple function scenes, the function scene that does not conform to the expected function safety in the at least one function scene, i.e., the target function scene, is determined through the evaluation result.
[0057] The safety requirement condition refers to a safety requirement condition that needs to be met by the target function scene that does not conform to the expected function safety to conform to the expected function safety, and is also a condition that needs to be met by the target function scene to eliminate the influence brought by the target behavior. The safety requirement condition can be set according to the target behavior and the target function scene, the safety requirement condition can also be artificially set according to experience and requirements, and the safety requirement condition can also be set according to actual application scenarios.
[0058] The threshold parameters refer to some parameters of the vehicle when the vehicle is intelligently driven, including but not limited to: vehicle speed, vehicle torque, vehicle control time, vehicle acceleration, probability of vehicle violation of traffic rules, etc. The threshold parameters include probability type and numerical type thresholds. The threshold parameters can be set according to target behavior and target function scenarios. The threshold parameters can also be set by experience and demand through human setting. The threshold parameters can also be set according to actual application scenarios.
[0059] In an optional embodiment, the target behavior can correspond to multiple function scenarios, i.e., the target behavior corresponds to at least one function scenario of the trigger condition. Based on the vehicle behavior and risk assessment, an evaluation result is obtained, and it is determined whether there is a function scenario that does not meet the expected function safety in the at least one function scenario, i.e., a target function scenario is determined. According to the target behavior in the target function scenario, a safety requirement condition of the target function scenario is artificially determined, and a threshold parameter for adjusting the target function scenario is determined according to the safety requirement condition of the target function scenario, i.e., the threshold parameter associated with the target behavior is increased according to the safety requirement condition of the target function scenario, the adjusted target function scenario is determined, and the vehicle function scenario is determined.
[0060] In the present disclosure, by adjusting the function scenario, the rationality and accuracy of the vehicle function scenario are effectively improved.
[0061] Table 2
[0062] Optionally, the threshold parameter associated with the target behavior is added to the target function scenario based on the safety requirement condition to obtain the vehicle function scenario, including: obtaining the behavior type of the target behavior; determining the threshold type according to the behavior type of the target behavior, wherein the threshold type includes at least one of the following: probability threshold and numerical threshold, the probability threshold is used to represent the threshold corresponding to the probability of occurrence of the target behavior, and the numerical threshold is used to represent the threshold corresponding to the associated numerical value in the target behavior; determining the threshold parameter based on the threshold type and the safety requirement condition; adding the threshold parameter to the target function scenario to obtain the vehicle function scenario.
[0063] The behavior type refers to the type of vehicle motion state determined according to the parameters and types of the vehicle. Each target behavior type corresponds to a threshold type, and the target behavior type is divided into a probability type and a numerical type. The probability type of the target behavior corresponds to a probability threshold, and the numerical type of the target behavior corresponds to a numerical threshold.
[0064] The probability threshold refers to a vehicle target behavior that cannot be determined by a specific numerical value, for example, the probability of a vehicle violating traffic rules. The probability threshold is generally applicable to industry regulations and is used to determine the residual safety risk that still exists when a certain measure is taken during vehicle operation. The probability threshold can be set according to the target behavior and the target functional scenario, and the probability threshold can also be set artificially according to experience and demand, and the probability threshold can also be set according to the actual application scenario.
[0065] The numerical threshold refers to a vehicle target behavior that can be determined by a specific numerical value, for example, the acceleration of the vehicle. The numerical threshold is generally applicable to national and industry standards and is used to determine whether a collision or other traffic accident risk will occur during vehicle operation. The numerical threshold can be set according to the target behavior and the target functional scenario, and the numerical threshold can also be set artificially according to experience and demand, and the numerical threshold can also be set according to the actual application scenario.
[0066] In an optional embodiment, the behavior type of the target behavior is obtained, and it is determined that the behavior type of the target behavior is a probability type or a numerical type. If the behavior type of the target behavior is the probability type, it is determined that the threshold parameter is the probability threshold, the probability threshold is used to represent the threshold corresponding to the probability of the probability type target behavior, the probability threshold is determined based on the threshold type being the probability threshold and the safety requirement condition, and the probability threshold is added to the target functional scenario to obtain the vehicle functional scenario. If the type of the target behavior is the numerical type, it is determined that the threshold parameter is the numerical threshold, the numerical threshold is used to represent the threshold of the numerical type target behavior of the vehicle, the numerical threshold is determined based on the threshold type being the numerical type and the safety requirement condition, and the numerical threshold is added to the target functional scenario to obtain the vehicle functional scenario. For example, Table 2 is a threshold parameter confirmation table corresponding to the vehicle target behavior, and the threshold parameter is determined as shown in Table 2, where the target functional scenario is the vehicle over-the-air diagnostics (ODC) scene of the navigation on pilot (NOP) function. The numerical threshold such as acceleration and displacement deviation is obtained by calculation, for example, Table 3 is a longitudinal acceleration confirmation table, and the longitudinal acceleration ≤ Xm / s 2 is obtained as shown in Table 3.
[0067] The threshold parameter is obtained by the threshold parameter functional use case, and the lane and other parameters are obtained to calculate the specific numerical value of the threshold parameter. Thus, the specific numerical value of the threshold parameter is obtained according to the specific situation. After the threshold parameter is determined, the threshold parameter is added to the target functional scenario to obtain the vehicle functional scenario.
[0068] Table 3
[0069] In the present disclosure, the specific threshold parameter value is obtained through the threshold parameter function use case, so that the threshold parameter acquisition has flexibility, the adaptability of the threshold parameter is improved, and the applicable range of the vehicle function scene is greatly improved.
[0070] Optionally, the target behavior of the intelligent driving function in the function use case is analyzed to determine at least one function scene containing a trigger condition corresponding to the target behavior and a vehicle behavior of the vehicle, including: determining that the behavior containing a preset keyword in the multiple behaviors corresponding to the intelligent driving function is the target behavior; determining that the function scene in which the target behavior of the intelligent driving function exists under different function scenes is at least one function scene; determining the vehicle behavior corresponding to the target behavior in the at least one function scene based on a preset correspondence, wherein the preset correspondence is used to represent the correspondence between the target behavior and the vehicle behavior in different function scenes.
[0071] The above-mentioned preset keyword refers to a keyword of hazard and operability study, which is a keyword of a structured safety evaluation method. The selected keywords of hazard and operability study include but are not limited to: cannot / can not, unexpected, too early, too late, too small / too little, too large / too much, reverse, logical opposite, partial function, simultaneous action with other functions, etc. When the behavior containing the above-mentioned preset keyword in the multiple behaviors corresponding to the intelligent driving function is determined as the target behavior.
[0072] Table 4
[0073] The above-mentioned preset correspondence refers to the correspondence between the target behavior and the vehicle behavior in different function scenes, wherein the above-mentioned preset correspondence can be set according to the target behavior and the vehicle behavior, the above-mentioned preset correspondence can also be set artificially according to experience and demand, and the above-mentioned preset correspondence can also be set according to the actual application scene. In an optional embodiment, the vehicle includes multiple behaviors when the intelligent driving function is started. When the behavior containing the preset keyword in the multiple behaviors is determined as the target behavior. The function scene containing the target behavior is at least one function scene, i.e. the target function scene. Based on the preset preset correspondence, the vehicle behavior corresponding to the target behavior in the at least one function scene is determined. For example, Table 4 is a vehicle behavior confirmation table.
