The paper investigates the possible practical virtual sensing solutions for electric drive trains. Two types of solutions: virtual sensors for machine sensorless control and physical sensor on-board diagnostics are particularly addressed, which provide the advantages of system cost reduction and reliability enhancement. Various virtual sensor configurations with advanced control and signal processing techniques are studied and their performance are compared based on the state of the art survey and preliminary simulation. The opportunities and challenges for the application of these virtual sensor configurations in electrified transportation system are also discussed.
