Abstract
Currently, almost all automotive and supplier companies are trying to expand Model Based Development (MBD) (1) (2) (3) (4) for control system development. Conventional development processes depend heavily on actual engine and vehicle testing, which means that control logic design can not start before the hardware is completed. And when performance is not sufficient, hardware and control design iteration is required. To shorten the development period, concurrent development of hardware and software is effective. Moreover, the control logic complexity is becoming higher in accordance with the implementation of new sensors, actuators, and improved control system performance. In turn, this increased complexity results in a huge control logic parameter calibration task. Various studies that use modelling to reduce calibration measurements have been tried. To expand MBD throughout our development process, we require that models are developed in a rapid and timely manner. In this paper, we discuss the concepts of MBD and concurrent development, and introduce some example applications. We also describe some key points for efficient model development.
