  • Patent number: 10442459
    Abstract: A vehicle and a steering system of a vehicle. The steering system includes a steering column emulator that generates an electrical driving signal in response to a driver input, a steering rack assembly that receives the electrical driving signal from the steering column emulator and controls steering of the vehicle as indicated by the received signal, and a backup system. The backup system provides a backup electrical driving signal to the steering rack assembly upon a failure of the steering column emulator, and the steering rack assembly steers the vehicle as indicated by the backup electrical driving signal upon the failure of the steering column emulator.

  • Patent number: 10427705
    Abstract: A steering system for an automotive vehicle is disclosed. The steering system includes a steering column assembly, a steering wheel assembly secured to the steering column assembly, the steering wheel assembly comprising a steering wheel frame, a steering wheel rim, and a hub, and an emulator enclosed within a housing, the emulator secured to the steering column assembly. The steering wheel frame and the hub are stationary and the steering wheel rim rotates relative to the steering wheel frame and the hub.

  • Publication number: 20130323525
    Abstract: An automotive product having a plurality of components coated with a refractory interface coating and method for making the same are provided. The automotive product may include at least a first component and a second component configured to interconnect and engage one another. The first component may be composed of a first high-density material. The second component may be formed of a second lower-density material. A refractory interface coating may be applied at the interconnection between the first and second components to provide an enhanced surface finish to limit friction, prevent metallurgical bonding between the first material and second material, provide a barrier against galvanic corrosion, and provide a thermal barrier between the first component and second component to guard against thermal deformation or change in dimension of the second component.
