  • Publication number: 20100257139
    Abstract: A method for validating variable data transmitted in a vehicle having at least one primary processor and at least one secondary processor includes generating a control copy and a redundant copy of the variable data in the at least one primary processor, providing the redundant copy of the variable data to the at least one secondary processor over a period of time, calculating one or more average values for the redundant copy of the variable data over the period of time in the at least one secondary processor, generating a transmittal message using the control copy of the data in the at least one primary processor during the period of time, providing the transmittal message to the at least one secondary processor, and comparing the transmittal message with the one or more calculated average values for the redundant copy of the variable data in the at least one secondary processor.

  • Patent number: 7747359
    Abstract: A vehicle includes a semi-active suspension including suspension dampers controllably adjustable in accordance with electronic stability control commands and ride and handling commands. Vehicle steering response states, turning direction states and vehicle dynamics states are binary coded in respective state variables and suspension control calibrations are binary coded in calibration words. Integrity and security of state variables and calibration words are ensured in efficient binary digit resource allocation schemes.

  • 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.
