Propulsion system for hybrid vehicle, has controller which varies operating conditions of electric motor/generator system in response to battery condition, state of electric motor, and coolant temperature of internal combustion engine

摘要

A controller (28) varies the operating conditions of an electric motor/generator during engine cranking sequence in response to the battery condition, state of electric motor, coolant temperature of internal combustion engine. Independent claims are included for the following: (1) propulsion system controller; (2) propulsion system operating method; and (3) propulsion system state varying method.
