System and Method of Extending Regenerative Braking in a Hybrid Electric Vehicle

摘要

A method of generating brake force to decelerate a vehicle is provided. The vehicle includes an internal combustion engine coupled to an input of a first electric energy device, the first electric energy device having an output coupled to a transmission device, and a second electric energy conversion device coupled downstream of the transmission device, the first and second electric energy conversion devices being powered at least by a battery. The method includes during a deceleration condition, generating brake torque via the second electric energy conversion device to generate electric energy storable in the battery; and rotating the internal combustion engine via torque output from the first electric energy device to deplete electric energy from the battery.
