Detailed Description
Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. In the drawings, like reference numbers indicate identical or functionally similar elements. Although various aspects of the embodiments are illustrated in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
The word "exemplary" is used herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.
In addition, numerous specific details are set forth in the following detailed description in order to provide a better understanding of the present application. It will be understood by those skilled in the art that the present application may be practiced without some of these specific details. In some instances, methods, means, elements, and circuits have not been described in detail as not to unnecessarily obscure the present application.
It should be noted that, a possible sequence of steps is shown in the following figures, and is not limited to the strict order of the sequence. Some steps may be performed in parallel without mutual dependency.
Specifically, fig. 1 shows a flowchart of a vehicle security processing method according to an embodiment of the present application. As shown in fig. 1, the method is applied to an automatic driving car, and the method may include:
s100, acquiring a target dangerous level corresponding to a target dangerous event, a corresponding target trigger event and a target trigger event probability corresponding to the target trigger event.
It is understood that the target risk event may be regarded as a risk event as a target object of interest. A dangerous event may be considered a dangerous event caused by failure of a vehicle component in the vehicle as a whole of an automatically driven automobile, external disturbance, mutual failure between vehicle components, or lack of a control mechanism, or the like. Each vehicle component may correspond to a plurality of hazard events. The target trigger event may be considered a trigger event that is a target object of interest, and the trigger event may be considered a factor that causes a dangerous event. The target trigger event probability may be regarded as a probability of occurrence corresponding to a target trigger event as an object of interest. The target risk level is used to characterize a risk severity level of the target risk event.
In one implementation, the collision of the autopilot is taken as the target dangerous event, the corresponding relationship between the target dangerous event and the target dangerous level, the corresponding relationship between the target dangerous event and the target trigger event, and the corresponding relationship between the target trigger event and the target trigger event probability can be referred to as the following table 1.
TABLE 1
It is to be understood that a collision here may be considered as a collision of an autonomous car with a car travelling in front or a car collision of an autonomous car travelling in rear.
As an implementation scheme, the triggering event of the dangerous event and the probability corresponding to the triggering event can be obtained through a great number of experiments. The risk event class corresponding to the risk event may be classified based on a predetermined classification criterion. Preferably, the classification criteria may be divided with reference to the IEC61508 standard or the road vehicle function safety standard (ISO 26262) in the safety integrity level SIL.
It will be appreciated that table 1, which is formed by the above correspondence between the target dangerous event and the target dangerous level, the correspondence between the target dangerous event and the target trigger event, and the correspondence between the target trigger event and the target trigger event probability, is merely an exemplary illustration, and in other possible implementations, there may be multiple target dangerous events corresponding to the same table, and each target dangerous event may correspond to multiple target trigger events, which is not enumerated herein.
S102, determining safety index information corresponding to the target trigger event according to the target trigger event probability and the target dangerous event level.
It will be appreciated that the security index information corresponding to the target trigger event may be used to characterize the security level of the target trigger event. In one possible implementation scheme, according to the target trigger event probability and the target dangerous event level, the determining the security index information corresponding to the target trigger event may specifically be taking the product of the target trigger event probability and the target dangerous event level as the security index information corresponding to the target trigger event. It will be appreciated that the currently determined target risk event level is a severity level, and cannot be directly calculated with the probability value of the target trigger event probability, and the target risk event level needs to be converted into a probability form.
Step S102 will be exemplarily described below using the target trigger event as a brake operation delay. In one possible implementation, the target hazard classes may be classified based on the IEC61508 standard in the safety integrity class SIL, for example into 5 classes. If the exposure rate of the braking operation is very high in the whole life cycle of the automobile, it can be defined as 1, the probability of occurrence of the operation delay is 0.01, the probability of occurrence of the casualties is 0.1, the probability of the target hazard class is 10-3, the probability of occurrence of the casualties is the result, and the highest class 5 corresponding to the severity consequences is SIL4, the safety index information (safety class) of the braking operation delay is SIL4. It will be appreciated that the safety levels SIL are divided into four levels, SIL1, SIL2, SIL3, SIL4, with the levels increasing in sequence.
S104, determining target vehicle components matched with the target trigger event.
It is understood that the target vehicle component may be an associated feature on the autopilot that triggers an event. For example, taking the above-mentioned target trigger event as an example, when the target trigger event is a distance detection failure, the target vehicle component corresponding to the target trigger event is a distance detection sensor, and when the target trigger event is a brake operation delay, the target vehicle component corresponding to the target trigger event is a brake controller.
S106, acquiring expected functional safety index information corresponding to the target vehicle component.
It will be appreciated that the expected functional safety index information corresponding to the target vehicle component is used to characterize the expected functional safety level of the target vehicle, which is required to meet the safety development requirements of the vehicle component. The safety development requirements of the vehicle component may be predetermined based on performance requirements of the vehicle component, etc., for example, the intended functional safety level of the vehicle component may be SIL3, etc.
S108, if the safety index information does not meet the expected functional safety index information, carrying out safety processing on the target vehicle component.
It will be appreciated that if it is determined that the safety index information is less than the intended functional safety index information, the safety index information is deemed to satisfy the intended functional safety index information, otherwise the safety index information is deemed not to satisfy the intended functional safety index information. If the safety index information meets the safety index information of the expected function, the target triggering event corresponding to the safety index information can be accepted to affect the whole automobile, and at the moment, the safety processing of the target automobile component corresponding to the target triggering event is not needed. If the safety index information does not meet the safety index information of the expected function, the target triggering event corresponding to the safety index information has larger influence on the whole automobile of the automobile, is unacceptable, and needs to carry out safety treatment on the target automobile component corresponding to the target triggering event.
In one possible implementation, the performing the security process on the target vehicle component in step S108 may include:
and sending the safety processing information to the terminal, wherein the safety processing information comprises the component identification of the target vehicle component needing to be subjected to safety processing.
It can be understood that by sending the component identification security information including the target vehicle component to be processed safely to the terminal, the user can quickly locate the target vehicle component to be processed safely, so as to process the target vehicle component safely, and improve the function optimization efficiency of the target vehicle component.
In one possible implementation, the security process may refer to improving the functionality of the target vehicle component corresponding to the target trigger event or adding constraints to the functional operation of the vehicle component. For example, as described above, when the target trigger event is a distance detection error and the target vehicle component corresponding to the target trigger event is a distance detection sensor, the safety process for the target vehicle component may be to optimize the detection performance of the distance detection sensor, for example, improve the measurement sensitivity of the distance detection sensor, and so on. Still further exemplary, as described above, when the target trigger event is a brake operation delay and the target vehicle component corresponding to the target trigger event is a brake controller, the safety process for the target vehicle component may be to reduce a reaction event of the brake controller, such as increasing a data transmission speed, or the like.
It will be appreciated that the security process in the example given above is only a preferred manner, and that in other embodiments, corresponding improvements may be implemented based on the target functional requirements of the target vehicle component, and are not enumerated here.
According to the method and the device, the safety indexes of the triggering events can be screened in advance based on the expected functional safety index requirements of the vehicle components, the later test verification work is reduced, the vehicle components corresponding to the triggering events with the safety indexes not reaching standards can be safely processed, the optimization flow is saved, and the safety processing efficiency of the vehicle components is improved.

In one possible implementation, verifying the security of the target trigger event may include reproducing the target trigger event and testing the autonomous vehicle to verify a security performance indicator of the target trigger event. Specifically, the test for the reproduction of the target trigger event for the automatic driving vehicle may refer to a specific test procedure in the prior art, and will not be described herein.

s200, acquiring a vehicle component and a preset operation scene corresponding to the vehicle component.
It is understood that the preset operating scenario is used to characterize the driving environment of the vehicle component. In one possible implementation, the preset operating scenario may include, but is not limited to, a road scenario, a traffic environment, a meteorological condition, and the like. The preset operating scenario corresponding to the vehicle component may be an operating scenario under a certain preset condition, and the preset condition may include, but is not limited to, a preset time. Corresponding preset operation scenes under different preset conditions are different.
S202, determining a dangerous event corresponding to the vehicle component according to the vehicle component and a preset operation scene corresponding to the vehicle component.
