Magnetorheological (mr) clutches for hybrid drivetrain power distribution

Abstract

Systems and techniques for controlling a power distribution of a hybrid powertrain system using magnetorheological (MR) clutches. In embodiments, MR clutches may be used to control the power transfer from a mechanical power source to a plurality of loads. For example, mechanical power produced by a mechanical power source (e.g., an internal combustion engine (ICE)) may be transferred to each load of the plurality of loads using an MR clutch respectively connected to each load. In this example, the amount of mechanical power transferred from the mechanical power source to each of the loads of the plurality of loads may be controlled and/or managed using the MR clutch connected to each respective load. In embodiments, a load may be engaged or disengaged from the mechanical power source gradually, such as by ramping up or ramping down the amount of mechanical power transferred via the MR clutch to the load.
