Abstract: In recent years, automotive electronic control systems have become more advanced and their application has expanded beyond the engine to include the powertrain chassis and other vehicle systems. As a result, the control algorithms have become much more complicated. This paper presents a design support system that allows more efficient development of electronic control systems. This support system consists of a NOAH (Nissan Operation Aid with High-level language) controller for automotive applications and a software support environment. The controller is built around a 68000 general-purpose microprocessor. It is provided with many input/output ports and a firmware job manager which is tailored for automotive control. The software management offers control input/output specifications, program execution and associated documentation. Using this support system, complicated control programs can easily be written in C language and efficiently implemented in the NOAH controller. Another advantage is that the use of this system is not limited to the laboratory: it can also be installed in a vehicle during the development process. Results have verified that this system greatly enhances the efficiency of electronic control system development.
