Outline
A Model-Based System Engineering (MBSE) approach has been proposed to construct a human-vehicle takeover requirement model, aiming to achieve complex functionality requirement management. This paper takes the human-vehicle takeover function application scenario as a use case, where the driver and the vehicle are considered as the main elements in accomplishing tasks together. The interaction capability is derived by combining the psychological, perceptual, and behavioral characteristics of humans in takeover tasks. Activity and sequence diagrams are established according to the takeover process, and a Systems Modeling Language (SysML) model tool is used for system capability allocation and system model establishment. The effectiveness and feasibility of this method have been verified through a case study and a comparison with traditional requirement analysis method has been conducted to demonstrate the advantages of this approach in managing complex functionality requirements.
