Guidelines for Determining ASIL Levels of Electrical and Electronic Systems
1 Scope
This document presents methods for determining the ASIL (Automotive Safety Integrity Level) of electrical and electronic systems in road vehicles. Determine the Department of Electrical and Electronics
The traditional ASIL (Automotive Safety Integrity Level) is required by GB/T 34590.3-2022.
This document applies to equipment and safety equipment containing one or more electrical/electronic systems installed on mass-produced road vehicles other than mopeds.
All related systems.

4 Hazard analysis and risk assessment
4.1 Identification of hazards
Hazard Analysis and Risk Assessment (HARA) is an analytical process that identifies potential hazards and combines them with operational scenarios to form a set of
Assess the risk of each hazardous event to determine its ASIL level and safety target.
Dependent item definition is a prerequisite for HARA. Hazard identification can be achieved through different hazard analysis techniques. This document gives
An example of hazard identification using Hazard and Operability Analysis (HAZOP) techniques is given. HAZOP is an exploratory analysis method,
It can be used to identify and evaluate the abnormal performance of related items, and it is helpful to check the operation of related items at the vehicle level in a structured and systematic manner.
The analysis method assumes different abnormal performances by adding appropriate guide words to each function of related items, and the abnormal function table
could now result in a hazard that could be harmful to the occupants of the target vehicle, other vehicles and their occupants, or other persons at risk, such as
Pedestrians, cyclists, or maintenance personnel in the vicinity of the target vehicle cause potential injury.
Other effective methods can also be used to identify relevant hazards. This document does not recommend or support a specific hazard identification method.
Identification is part of hazard analysis and risk assessment. Appendix A describes the motion behavior of the vehicle along different axes.
The following is an example of the application of a simple HAZOP method to identify hazards caused by potential abnormal performance of related items.
Harmful. For example, based on the functionality described in the dependency definition, consider the role and capabilities of the dependency actuator, and then assume the following dependency
Abnormal performance of item function.
