Abstract

The electric motor in a hybrid electric vehicle is an integral part of the vehicle as a dynamic system. As such, the fast electrical dynamics of the electric machine contain information on the impending response of the vehicle system. It is possible to utilize the fast dynamics of the inner loop response as analytical redundancy so that sensors can be minimized or eliminated. The availability of dedicated electric motor control DSPs and high MIPs DSPs provide added impetus to employ the DSP for more refined sensorless control and for prognostics
