Identify customer needs and expectations for vehicle functionality and safety
This task involves understanding the needs and expectations of the customers regarding the functionality and safety of the vehicle. It is crucial to gather comprehensive information to ensure that the vehicle meets the requirements of the customers. What are the key factors that customers look for in terms of functionality and safety? What features should the vehicle have to meet these needs and expectations? Gather feedback from customers through surveys, interviews, and market research to identify their preferences and concerns. This task will contribute to the overall process by providing valuable insights that will guide the design and development of the vehicle. Challenges that you may encounter include conflicting customer needs and expectations, complex requirements, and ambiguity. To overcome these challenges, engage in regular communication with customers and stakeholders to clarify requirements, prioritize needs, and manage expectations.
Review and analyze system requirements for vehicle functionality and safety
In this task, you will review and analyze the system requirements for the functionality and safety of the vehicle. System requirements define the capabilities and behavior of the vehicle and ensure that it meets the desired functionality and safety standards. Analyzing these requirements will help identify any gaps, contradictions, or potential issues that need to be addressed. It is important to ensure that the requirements are clear, complete, and aligned with the customer needs and expectations. Consider the impact of the requirements on the overall design and performance of the vehicle. Challenges that you may encounter include conflicting requirements, incomplete specifications, and technical complexities. To overcome these challenges, collaborate with the relevant stakeholders such as system architects, engineers, and designers. Document any changes or updates to the requirements for future reference.
Design a safety concept for the driving/designated function of the vehicle
In this task, you will design a safety concept for the driving or designated function of the vehicle. The safety concept defines the measures and strategies to ensure the safety of the vehicle and its occupants. Consider various factors such as potential hazards, risk assessments, and mitigation strategies. Identify the critical safety functions and define the necessary safety mechanisms and controls to address them. The safety concept should align with the overall functionality and performance requirements of the vehicle. Challenges that you may encounter include complex safety considerations, integration of safety features with the overall design, and compliance with regulatory standards. To overcome these challenges, collaborate with experts in functional safety engineering, conduct thorough risk assessments, and ensure compliance with relevant safety standards.
Perform safety analyses including FMEA and FTA
In this task, you will perform safety analyses including Failure Mode and Effects Analysis (FMEA) and Fault Tree Analysis (FTA). FMEA helps identify potential failure modes, their causes, and their effects on the vehicle's safety. FTA, on the other hand, analyzes the logical relations between failures and determines the probability of system failures. These analyses contribute to the identification and mitigation of safety risks. Document the results of the analyses and prioritize the identified risks based on their severity. Challenges that you may encounter include complexity in analyzing failure modes and logical relations, limited availability of relevant data, and interpretation of analysis results. To overcome these challenges, collaborate with experts in safety analysis, gather relevant data through testing and simulations, and use specialized tools for analysis.
Verification and validation of safety requirements
In this task, you will verify and validate the safety requirements of the vehicle. Verification involves checking whether the safety requirements have been implemented correctly, while validation ensures that the implemented safety measures are effective in mitigating safety risks. Develop test plans and procedures to verify and validate the safety requirements. Conduct tests, inspections, and simulations to assess the performance and effectiveness of the safety measures. Document the test results and identify any non-conformities or issues that need to be addressed. Challenges that you may encounter include complex test scenarios, resource constraints, and ensuring the repeatability and reproducibility of tests. To overcome these challenges, collaborate with the test team, use standardized testing methods, and prioritize the most critical safety requirements for testing.

Support in defining safety goals and ASILs
This task involves supporting the definition of safety goals and Automotive Safety Integrity Levels (ASILs) for the vehicle. Safety goals define the desired levels of safety performance, while ASILs determine the necessary safety requirements based on the severity of potential hazards. Collaborate with the safety team to identify and prioritize safety goals based on the risk assessment. Determine the appropriate ASIL for each safety goal considering factors such as potential harm, exposure, and controllability. Documentation of safety goals and ASILs is essential for ensuring clarity and traceability throughout the development process. Challenges that you may encounter include complex risk assessments, conflicting safety goals, and uncertainty in assigning ASILs. To overcome these challenges, consult with functional safety experts, conduct thorough risk assessments, and use guidelines and standards for assigning ASILs.
Safety reporting to stakeholders
In this task, you will provide safety reports to stakeholders to communicate the status and progress of safety activities. Safety reports should include information on safety goals, risk assessments, safety requirements, safety measures, and any identified non-conformities or issues. Determine the frequency and format of the reports based on the needs and expectations of the stakeholders. Ensure that the reports are clear, concise, and provide sufficient details for stakeholders to understand the safety status of the project. Challenges that you may encounter include presenting technical information to non-technical stakeholders, managing the volume of information, and ensuring consistency in reporting. To overcome these challenges, use visual aids such as charts or diagrams to simplify complex information, summarize key findings and recommendations, and maintain a standardized reporting format.
Coordination of safety activities with internal and external partners
In this task, you will coordinate safety activities with internal and external partners involved in the development process. Safety activities require collaboration and coordination among various stakeholders such as engineers, designers, suppliers, and regulatory authorities. Communicate safety requirements, goals, and progress to ensure alignment and consistency across the development team. Establish clear communication channels and mechanisms to address any safety-related issues or concerns. Challenges that you may encounter include conflicting priorities, communication gaps, and ensuring compliance with regulations and standards. To overcome these challenges, establish regular communication channels, schedule meetings or workshops to facilitate collaboration, and ensure compliance through regular audits and reviews.
Communicate the safety design and validation to the development team
In this task, you will communicate the safety design and validation outcomes to the development team. The safety design and validation outcomes provide guidance and information to the development team on the necessary safety measures and controls that need to be implemented. Ensure that the communication is clear, concise, and easily understandable by the development team. Provide supporting documentation, such as safety requirements, test reports, and design documents, to facilitate the implementation of the safety design. Challenges that you may encounter include technical complexity, information overload, and ensuring comprehension by all members of the development team. To overcome these challenges, utilize visual aids or diagrams to simplify complex concepts, break down information into manageable chunks, and conduct training or workshops to enhance understanding.
