Abstract:There have been many difficulties in system functional requirements， such as difficult to accurately identify， difficult to fully identify， difficult to identify by structured method， etc. By firstly identifying all operating states of the system， and then successively identifying the response output of the system to all external input signal combinations in each operating state， the complete functional requirements of the system could be obtained after synthesis， which would greatly improve the integrity and accuracy of the identification of system functional requirements. The functional requirements identification method was structured， and was easy to be used and automated. Combined with the system use cases， external actors， external interface relationship， and effective range of external signals， an analysis method based on automatic control theory was proposed to improve the integrity and accuracy of system functional requirements. Finally， an example of adaptive cruise system was given to verify the effectiveness of the proposed method.

Key words:requirement analysis;functional requirement;integrity of requirement;structured requirement analysis;automotive control system
