This paper introduces one functional safety development solutions of Dual Clutch Transmission (DCT) equipped with Position 2 (P2) hybrid control system, which mainly includes the concept development stage (only for selected part), the system development stage (only for selected part), the hardware development stage (only for selected part) and the software development stage (only for selected part). It is carried out based on ISO 26262 standard and the selected system topology (details can be found in the paragraph). In the concept development stage of the DCT equipped with P2 hybrid control system, the hazard analysis and risk assessment of the item will be carried out based on the selected objects according to defined working condition. Especially the hybrid transmission control features are analyzed. And the safety goals will be summarized according to the evaluation results. The preliminary system architecture, functional safety requirements and concepts will be analyzed based on the obtained safety goals and selected objects. In the system development stage, the detailed system architecture, technical safety requirements and concepts will be analyzed based on the functional safety requirements with the help of the safety analysis tool. The system safety requirements for software and hardware will also be decomposed, and the decomposition strategy is described in detail.
