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.

The present application provides a steering mechanism, a vehicle, and an apparatus and method for producing a steering mechanism, and belongs to the technical field of vehicles. Wherein the steering mechanism comprises a first directive wheel, a second directive wheel, a first driving device, and a second driving device. The first driving device is connected to the first directive wheel; and the second driving device is connected to the second directive wheel.
