Hybrid powertrain's operating point controlling method for vehicle, involves optimizing operating point of powertrain that determines speed set-point of heat engine, torque to wheels, and power delivered or stored by energy storage element

摘要

The method involves optimizing an operating point of a hybrid powertrain that determines speed set-points of a heat engine, torque to wheels and power delivered or stored by an energy storage element (S) i.e. battery. The heat engine of the powertrain is connected to the wheels by a kinematics chain (C), where the speed of the heat engine is chosen based on charging state of the storage element. An electric variator is formed of electrical machines (ME1, ME2) that examine power supplied to the wheels by the engine. An independent claim is also included for a device for controlling an operating point of a hybrid powertrain in a vehicle.
