Abstract

Official abstract text for this publication.

A system and method for recovering the optimum power level during regenerative mode is disclosed. Equations for determining the optimum regenerative power level receivable by an energy storage system, for example for any given deceleration event, are derived and disclosed. The equations consider various losses such as the efficiency of the electric motor generator in the generator mode, wind resistance, rolling resistance, transmission losses, engine losses, and losses in the energy storage system. Also disclosed is at least one embodiment of a procedure for controlling a hybrid drive system to achieve the optimum energy recovery.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method of controlling regenerative braking in a hybrid electric vehicle, comprising: detecting a deceleration state of the vehicle, wherein detecting the deceleration state includes detecting a torque provided from a transmission to the electric motor generator, and wherein the electric motor generator is coupled to the transmission; calculating a predicted vehicle energy loss for a vehicle using a vehicle controller, wherein the vehicle has an ele…
