  • Patent number: 11724737
    Abstract: A steering system and method can determine one or more position-related characteristics of a steering column of a machine, determine that the one or more position-related characteristics indicate that a resistive force is to be applied to the steering column, and control operation of an electric motor to apply the resistive force to the steering column, wherein a mechanical stop (e.g., a progressive mechanical stop) can be provided to restrict rotation of the steering column. One or more virtual stops may be set to limit rotation of the steering column by way of controlling the operation of the electric motor to apply the resistive force.

  • Patent number: 11292502
    Abstract: A steering assembly for a machine is provided. The steering assembly includes a frame. The steering assembly also includes a steering column mounted on the frame. The steering column includes a steering input device and a controller communicably coupled to the steering input device. The steering assembly further includes a steering wheel operably coupled to the steering column. The steering wheel is disposed adjacent to the steering input device.

  • Publication number: 20200086911
    Abstract: A machine is disclosed. The machine may comprise a steering device configured to move along a steering position range in response to a force applied on the steering device by a machine operator. The steering device may have at least one soft stop position along the steering position range. The machine may further comprise a biasing member mechanically coupled to the steering device and configured to apply an opposing force that opposes movement of the steering device when the steering device is at or beyond the soft stop position. A magnitude of the opposing force may be sufficiently low such that the machine operator can move the steering device past the soft stop position. The machine may further comprise an electronic control device configured to determine the soft stop position based on one or more operation conditions of the machine.
