    Abstract: A steering system for an automotive vehicle is disclosed. The steering system includes, in some embodiments, a steering shaft, a steering column jacket encircling at least a portion of the steering shaft, an emulator enclosed within a housing, the emulator coupled to the steering shaft, and a travel limiter assembly enclosed within the housing and coupled with the steering shaft, the travel limiter assembly comprising at least one rotational member having a pin and a groove configured to receive the pin, the groove including a stop portion. In some embodiments, the at least one rotational member and at least a portion of the steering shaft rotates within the housing and the pin travels within the groove until the pin encounters the stop portion after a predetermined degree of rotation of the steering shaft.

    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.

    Abstract: Methods and apparatus are provided for controlling a steering assist unit of a vehicle. The method includes receiving sensor data indicating a wheel position of a wheel relative to a frame of the vehicle, and determining a travel limit value for the steering assist unit based at least on the wheel position of the wheel. The method further includes outputting a control signal to control the travel of the steering assist unit based on the travel limit value.

    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.
