 This is a model of motor drive unit
 specifically parameterized for Motor Generator 1 (MG1),
 which is used as part of power-split hybrid electric vehicle.
+MG1 controls the power splitting of internal combustion engine
+to distribute engine's mechanical power for
+driving vehicle axle and generating electric power.
 This component is designed to be used
 as a reusable model.
