Filed:

Aug 16, 2001

Appl. No.:

09/931519

Inventors:

Michael C. Pfeil - South Charleston OH
Gary C. Fulks - Spring Valley OH
Paul F. Flanagan - Dayton OH

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

F16D 6536

US Classification:

701 70, 701 36, 188171

Abstract:

Apparatus, method and program product that controls the release of an electronically activated parking brake. An algorithm adjusts for cable stretch and limits the occurrence of over-release and wheel drag within the brake system. A controller monitors force incident on an actuator during a brake release operation. When a preset load is indicated, the controlling parameter of the algorithm transitions from force to position control. Once in position control, the controller uses previous position measurements and equipment specific constants to calculate a release point.

Assignee:

DELPHI TECHNOLOGIES INC.

International Classification:

G05G001/14

US Classification:

074/560000

Abstract:

A pedal emulator assembly and method for a motor vehicle. The assembly includes at least one pedal for generating a dynamic reaction force against an applied pedal force. The pedal is deformed as a result of the applied pedal force. The assembly further includes at least one sensor operably attached to the pedal for estimating the applied pedal force based on the pedal deformation. The method includes deforming at least one pedal with an applied pedal force. A dynamic reaction force is generated against the applied pedal force with the pedal. The applied pedal force is estimated based on the pedal deformation.
