  • Patent number: 7706941
    Abstract: A method and system for coordinating a vehicle stability control system with a suspension damper control sub-system includes a plurality of dampers, each of which are controlled directly by the suspension damper control sub-system. A plurality of sensors sense a plurality of vehicle parameters. A supervisory controller generates vehicle damper commands based on the plurality of vehicle parameters for each of the dampers. A damper controller in electrical communication with the supervisory controller receives the vehicle damper commands and generates sub-system damper commands based on a portion of the plurality of vehicle parameters for each of the dampers. The damper controller also determines if any of the vehicle damper commands for any one of the dampers has authority over the corresponding sub-system damper command.

  • Patent number: 5603217
    Abstract: A compliant master cylinder includes a primary piston and a secondary piston which are movable to provide fluid pressure to effect wheel braking in a vehicle. In addition, the master cylinder includes a compliant assembly which supplies conventional pedal feel and travel characteristics when the primary and secondary pistons are substantially immovable due to isolation the master cylinder from the wheel brakes. The compliant assembly includes a push rod piston that is movable against a selected amount of fluid pressure and spring force while the primary piston remains stationary. The fluid force is supplied by controlling the flow of fluid from behind the push rod piston through a flow restrictive orifice to a conventional fluid reservoir on the master cylinder assembly.
