Abstract

Official abstract text for this publication.

A method of improving fuel economy through electrical vehicle (EV) control of a hybrid vehicle having various modes includes applying an APS input by releasing a brake, identifying whether a second clutch is released when an input split mode command is applied from a first control unit, determining whether the second clutch is released, generating a target revolutions per minute (RPM) of an engine, comparing the target RPM of the engine with an actual RPM of the engine to generate a first motor torque in response to a difference therebetween through feedback control and feedforward control, applying an injection signal when the RPM of the engine is increased, applying an engine torque according to an engine torque restriction amount of the first control unit to complete a vehicle starting condition, and recognizing completion of vehicle starting when engine torque restriction requirement does not exist.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of improving fuel economy through electrical vehicle (EV) control of a hybrid vehicle having a starting mode in which a brake is released while a clutch is fixed, wherein the method is executed by a control unit including a hybrid control unit (HCU), the method comprising: releasing the clutch by a Transmission Control Unit (TCU) when an input split mode command is applied from the HCU; generating a target revolutions per minute (RPM) of an engine…
