High Performance and Cost-Effective Electronic Controller Architecture for Powertrain Systems

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.
