Method and apparatus for loss of control inhibitor systems
First Claim
1. A loss of control inhibitor system for a vehicle, said system comprising:
- an inceptor for receiving a control input from an operator of said vehicle, an effector for effecting a control output in response to said control input from said operator of said vehicle, an inceptor sensor, wherein said inceptor sensor measures a value of said control input, an effector sensor, wherein said effector sensor measures an actual effector output of said effector, means for modeling a relationship between said control input and said control output for a predetermined range of conditions, wherein said modeling means produces an expected effector output from said control input, means for determining a distortion metric, wherein said distortion metric comprises a difference between said expected effector output and said actual effector output, and means for providing a feedback force to said inceptor, wherein said feedback force is a function of said distortion metric.

Abstract
Active and adaptive systems and methods to prevent loss of control incidents by providing tactile feedback to a vehicle operator are disclosed. According to the present invention, an operator gives a control input to an inceptor. An inceptor sensor measures an inceptor input value of the control input. The inceptor input is used as an input to a Steady-State Inceptor Input/Effector Output Model that models the vehicle control system design. A desired effector output from the inceptor input is generated from the model. The desired effector output is compared to an actual effector output to get a distortion metric. A feedback force is generated as a function of the distortion metric. The feedback force is used as an input to a feedback force generator which generates a loss of control inhibitor system (LOCIS) force back to the inceptor. The LOCIS force is felt by the operator through the inceptor.
