A multi-function hitch accessory retaining device and method which includes an assembly comprising a housing, receiver engagement pin, biasing mechanism, fastener, and coupling pin that is inserted into an accessory shank and configured to easily engage and disengage a conventional hitch receiver as well as a method of firmly securing the shank within the hitch receiver tube.

A vehicle steering device in which turn signal switches are disposed along axial directions of grip members of left and right steering units. While the grip members are being operated in opposite forward and rearward directions when turning to the right or left, the turn signal switches are also operated in opposite axial directions upon turning to the right or left or the like, and therefore, are easily matched with the movements of the steering units. More specifically, there is continuity between the movement of the arms during turning and the movement of the fingers of the right and left turning indicators, and thus operation of the vehicle steering device is facilitated.

A driving operation apparatus for a vehicle, and a steering unit provided on a center display, an acceleration unit provided on a right display, and a braking unit provided on a left display become a driving operation system of a vehicle and is integrally modularized as one system, and the driving operation apparatus may have a display to assist to improve a passenger's entertainment in an autonomous driving situation and provide vehicle information and nearby information in a manual driving mode.

A selectively extendable length trolley for supporting and conveying various sized and configured containers for pieces or components in an industrial plant. The trolley includes an adjustable length trolley structure, front and rear adjustable frames and locating supports for the containers that include side supports adjustable in position in a transverse direction, orthogonal to the longitudinal direction (L). A steering control unit (2) of the trolley (1) is articulated to the front frame (32) and operates in such a way that the front wheel unit and the rear wheel unit are made to oscillate in opposite directions to keep the wheels aligned with the curved path to be followed. In a preferred embodiment, the front and rear adjustable frames are T-shaped providing an open or free space at the two sides of the central structure of the trolley.

In some embodiments, a vehicle may include a frame having longitudinal axis. The vehicle may include a steering assembly having a steering input and at least one wheel. The steering assembly may be coupled to the frame and configured to steer the vehicle based on input from a steering input. The vehicle may include a first drive wheel and a second drive wheel. The vehicle may include a steering position sensor configured to detect steering input including a position of the steering input and at least one of i) a rate of change of position of steering input and ii) steering position time. The vehicle may include at least one controller configured to process a signal from the steering position sensor and, in response to the processed signal, drive the first drive wheel and the second drive wheel, the first drive wheel being driven independent of the second drive wheel.
