  • Publication number: 20170080972
    Abstract: A drive-by-wire steering system on a vehicle requiring counter-steering includes a driver input mechanism, for example, a steering wheel, joystick, voice command receiver, or keyboard, and a control system. A sensor receives driver input and sends that information to the control system. An engagement mechanism, for example, a clutch, separates the driver input mechanism from controlling the vehicle. The control system further includes at least one actuator, a wheel, and a mechanical linkage controllable via the engagement mechanism in order for the control system to articulate a steering mechanism, for example, the front wheel of the vehicle, as appropriate.

    Abstract: In embodiments of the invention, a vehicle stabilization control unit may determine a control moment value for one or more gyroscopes coupled to a vehicle frame to exert for stabilization of the vehicle frame. A number of input axes for the flywheels of the one or more gyroscopes to precess may be increased in order to generate the determined control moment value. In some embodiments, the one or more gyroscopes are further coupled to a turntable, and increasing the number of input axes for the flywheels comprises rotating the turntable. Furthermore, in some embodiments, the one or more gyroscopes comprise at least two gyroscopes coupled inline to the vehicle frame (e.g., aligned lengthwise with respect to the front and rear wheel to spin and precess in opposite directions with respect to each other).
