Abstract
A steer-by-wire system may comprise: a first powerpack comprising a first motor; a second powerpack comprising a second motor; a steering rack operably coupled to the first motor of the first powerpack and the second motor of the second powerpack, the steering rack configured to be linearly movable in response to rotation of at least one of the first motor and the second motor, wherein a rotation ratio associated with the first motor and a rotation ratio associated with the second motor are different from each other. The steer-by-wire system may identify a linear position of the steering rack based on the position of the first motor and the position of the second motor using a Vernier algorithm.
