Electronic controllers for powertrain systems are required to meet the demands for increased system performance and functionality at reasonable cost. It is indispensable to examine the solutions from a range of view points synthetically for cost optimization. This paper describes a cost-effective hardware and software architecture of the electronic controllers for powertrain systems. A new method for noise reduction of a switching regulator, and a low standby current wakeup solution are also discussed as further functions needed for high performance powertrain systems.
