Abstract:
A method for a steer by wire steering system. The method includes determining a difference between a commanded steering ratio and an achieved steering ratio and determining whether the difference between the commanded steering ratio and the achieved steering ratio is greater than a threshold. The method also includes, in response to a determination that the difference between the commanded steering ratio and the achieved steering ratio is greater than the threshold, adjusting the commanded steering ratio to be equal to the achieved steering ratio. The method also includes, in response to a determination that the difference between the commanded steering ratio and the achieved steering ratio is greater than the threshold, selectively adjusting a bandwidth of a filter based on at least one vehicle characteristic of an associated vehicle and adjusting, using the filter, the commanded steering ratio to be equal to a desired steering ratio.
