  • Architecture using integrated backup control and protection hardware
    Patent number: 8340793
    Abstract: An electronic control configuration includes at least one secondary microprocessor operable to control a device. The at least one secondary microprocessor assumes protection control of the device responsive to a first type of failure by transmitting a protection control signal to a first effector. The at least one secondary microprocessor assumes backup control of the device responsive to a second type of failure by transmitting a backup control signal to a second effector. The backup control functionality of the at least one secondary microprocessor can be selectively disabled.
    Type: Grant

  • Controller and method of controlling a hydraulic control network with latching valve
    Patent number: 5922032
    Abstract: A control method for managing a hydraulic control system of a vehicle is disclosed. The method includes the steps of scheduling the invocation of a plurality of vehicle functions through system operations, which functions are used for operating the vehicle; prioritizing the invocation of the vehicle functions and associated operations by the system; performing the operations based on prioritization created in the step of prioritizing; and superseding the performance of one of the operations with the performance of a higher priority one of the operations. This occurs if the higher priority operation arises for performance during the performance of the one of the operations. A related controller is also disclosed.
