摘要： 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.

摘要： A method of testing an actuation system for positioning an actuator, the actuation system including a primary electronic system, a secondary hydro-mechanical system is disclosed. The method includes the steps of measuring the actual position of the actuation device as set by the primary electronic system; measuring the system inputs and computing an ideal actuator position based thereon; determining the difference between the actual actuator position and the ideal position. The difference is then compared to a first threshold value which represents a disturbance beyond which the system cannot safely operate. Control is transferred from the primary control to the secondary control if the difference exceeds the first threshold. If the difference is less than the first threshold, the difference is compared to a second threshold value which represents an operating condition that can be tolerated for a period of time. Control is transferred from the primary control to secondary control if the difference exceeds the second threshold for longer than the time period.

摘要： A velocity adaptive method for testing the control of dynamic devices of a system having a position schedule influenced by a dynamic factor is disclosed. The method includes the steps of introducing a step into the position schedule and causing a disturbance in the system; maintaining the step for an interval of time; removing the step; calculating step response by the system while accounting for the dynamic factor; and comparing the step response to a threshold value for determining one of the failure and successful operation of the control.

摘要： A vibration monitoring system employing a capacitive accelerometer determines the energy associated with one or more frequency components within the frequency spectrum of the vibration signal. The capacitive accelerometer operates as a mixer due to its time varying capacitance which provides a measure of the vibration. When the accelerometer is excited by an AC signal the output from the accelerometer comprises beat frequencies due to the mixing of the time varying capacitance and the AC signal. By changing the frequency of the AC signal the location of the beat frequencies in the frequency domain of the accelerometer output can be shifted. Subsequent bandpass filtering to attenuate frequencies except those associated with the frequency component and demodulation to bandshift the energy of the filtered signal energy to DC, creates a DC value which provides a measure of the energy present at the frequency component.
