Model-driven requirements validation for automotive embedded software using UML

Nowadays, A lot of effects are making a change in how the automotive field develops software. Some of these effects include: growing complexity of the embedded software; increasing amount of software in the vehicle; limited resources of development period, manpower, money; and the emergency of software-driven safety-critical systems. However, since all works including the communication about design, data, constraint, performance between supplier and original equipment manufacturer (OEM) are only document-driven, such document-driven development (DDD) process has some intrinsic problems. Obscure specification may generate errors and misunderstandings and so on. In this paper, the model-driven software development process is realized and that for a body control module (BCM) is demonstrated to verify and validate automotive embedded software requirements for solving these problems without any additional cost and equipments.
