Filed:

Mar 28, 2002

Appl. No.:

10/063188

Inventors:

Susan Rebecca Cikanek - Wixom MI
Kathleen Ellen Bailey - Dearborn MI
Natarajan Sureshbabu - Canton MI
Barry Kay Powell - Belleville MI

Assignee:

Ford Global Technologies, LLC - Dearborn MI

International Classification:

B60K 100

US Classification:

180 656, 701 22, 477 7

Abstract:

A method of distributing a torque demand in a hybrid electric vehicle having an internal combustion engine and an electric motor is provided. In hybrid operation, the motor initially starts the vehicle. When the vehicle desired power demand reaches a first vehicle operational parameter, a controller switches the torque demand to the engine. An accelerator pedal has a position sensor which determines a non-fixed pedal first position during transition between the motor and engine. The accelerator pedal also has a preset second position wherein a maximum of engine torque is requested. The controller , cognizant of the accelerator pedal first and second positions, linearly scales the accelerator pedal to provide a uniform torque-responsive accelerator pedal.

International Classification:

B60K 6/02

US Classification:

180 652, 903941

Abstract:

A method for operating a hybrid vehicle having a primary power generating system and a secondary power generating system coupled via a power transmission assembly for delivery of tractive force for the vehicle. The method includes determining acceleration of input speed to the power transmission assembly when the primary power generating system is deactivated, and inferring activation of the primary power generating system based at least in part on the acceleration of the power transmission assembly.

International Classification:

B60K 6/44
B60W 10/00

US Classification:

180 65225, 180 65265

Abstract:

A control method and control system for a hybrid electric vehicle powertrain with a multiple-ratio transmission is disclosed in which engine start events are separated in time from transmission ratio shift events to effect a smooth transition from an electric drive state with the engine off to a drive state in which the engine delivers driving power.

Appl. No.:

Inventors:

Susan Cikanek - Wixom MI, US

Assignee:

International Classification:

B60T008/64

US Classification:

303/152000

Abstract:

A regenerative braking system for use with a hybrid electric vehicle including an internal combustion engine , an electric motor/generator or transaxle assembly , and a transmission assembly which selectively receives torque from the engine and transaxle and delivers the received torque to vehicle's wheels . The engine is connected to the transmission assembly by use of a clutch . During regenerative braking events, the system automatically disengages clutch , thereby allowing a maximum amount of energy to be recovered by the transaxle assembly , as engine “drag” is eliminated. Furthermore, the system disengages clutch during idling conditions, and utilizes transaxle to provide a negative torque to the driveline, effective to recover energy and to simulate engine drag forces due to compression braking effects, thereby providing a driver of the vehicle with consistent feel during all operating modes.
