  • STEERING SYSTEM FOR AN AUTONOMOUSLY DRIVEN VEHICLE AND METHODS OF STEERING THE SAME
    Publication number: 20140277893
    Abstract: A steering system for an autonomously driven vehicle and methods of steering the vehicle are disclosed. A main controller signals a secondary steering assembly to operate in a first phase when a power steering controller is in a first mode and a second phase to steer the vehicle when the power steering controller is in a second mode. The main controller signals a friction device to actuate to a disengaged position when the power steering controller is in the first mode and the secondary steering assembly is in the first phase, and to signal the friction device to actuate to an engaged position to secure a steering wheel in an initial position when the power steering controller is in the second mode and the secondary steering assembly is in the second phase to allow the secondary steering assembly to steer the vehicle.

  • STEERING SYSTEM FOR AN AUTONOMOUSLY DRIVEN VEHICLE AND METHODS OF STEERING THE SAME
    Publication number: 20140214256
    Abstract: A steering system for an autonomously driven vehicle and methods of steering the vehicle are disclosed. A brake device is operable in a first phase to brake the vehicle when a power steering controller is in a first mode and operable in a second phase to steer the vehicle when the power steering controller is in a second mode. A main controller is in communication with a friction device to signal the friction device to actuate to a disengaged position when the power steering controller is in the first mode and the brake device is in the first phase, and signal the friction device to actuate to an engaged position to secure a steering wheel in an initial position when the power steering controller is in the second mode and the brake device is in the second phase to allow the brake device to steer the vehicle.
