Electronic control of automatic transmission systems have become indispensable in order to satisfy driver expectations of comfort and vehicle response. The increasing complexity of such systems has resulted in a huge increase of control data volumes handled by electronic transmission control units (ETCUs).This paper describes the development, operation and evaluation by JATCO Corporation and Nissan Motor Co., Ltd of a Read Only Memory (ROM) management system for use with ETCUs. The system makes extensive use of computer aided design(CAD) techniques to create ROM data from standard format drawings, and vice-versa.The paper also presents the evaluation system developed for ETCU use. Making use of computer simulated testing, this increases the reliability of units and reduces testing time.
