Requirement Modeling of Distributed Logic Control Systems Using Simulink
Nate Rolfes, Ford
Driver assistance technology features require coordination and control of ECUs, sensors, and actuators, that are distributed functionally throughout the vehicle and in constant communication through CAN networks. The systems engineer is challenged to design, validate, and verify these distributed control systems, which are composed of hardware and software from disparate sources. Engineering specifications typically describe system logic requirements with natural language, tables, diagrams, and flow charts. These “non-executable” requirements allow for ambiguities, typos, and logical errors that introduce defects into software implementations. In this session, Nate demonstrates how creating executable models of system requirements in Simulink® has reduced software defects and improved product development timing. He also explores some best practices and tools developed for efficiently implementing the requirement modeling methodology.
