Control Development for Hybrid Vehicle Powertrain with Magnetic Continuously Variable Transmission

This paper presents a control development for a hybrid vehicle powertrain with magnetic continuously variable transmission-MAGSPLIT. This is shown that in comparison with conventional continuously variable transmission (CVT) hybrid powertrain, a MAGSPLIT-based powertrain can provide similar functionality but with a number of advantages including efficiency improvement due to neglecting mechanical losses, inherent torsional vibration attenuation, and simplification of mechanical arrangement leading to improvement on powertrain safety and reliability. The proposed control strategy is developed with a MotoHawk hybrid transmission control unit (HTCU) and validated by both hardware in the loop (HIL) study and measurements from a MAGSPLIT-based powertrain brassboard.
