  • APPARATUS AND METHOD FOR CONTROLLING STEER-BY-WIRE SYSTEM TO PROVIDE IMPROVED FEEDBACK TO STEERING WHEEL
    Publication number: 20220266901
    Abstract: A steer-by-wire system can be controlled using a hypothetical or virtual model of a conventional automotive steering system such as an electric power steering (EPS) system in which a steering wheel is mechanically linked to one or more road wheels. The model of the EPS system may be implemented in algorithms or instructions of software. In order to reconstruct driving feedback similar to the conventional steering system in the steer-by-wire system, the steer-by wire system may use the model of the EPS system. For example, a controller of the steer-by-wire system controls an angular velocity of a steering feedback actuator of the steer-by-wire system operably connected with the steering wheel so as to provide a steering feedback to a driver or operator using the model of the EPS system.

  • Method for determining an absolute rotational position of a vehicle steering column
    Patent number: 8375779
    Abstract: A method for determining an absolute rotational position of a vehicle steering column is provided. In one exemplary embodiment, the method determines a relative position of a steering assist motor utilizing a relative position sensor. Thereafter, the method determines the absolute rotational position of the vehicle steering column based upon the relative position of the steering assist motor.
