Abstract
A steer-by-wire system includes a hand wheel actuator coupled to a steering column, a steering angle sensor coupled to the steering column and configured to measure movement of the steering column, a road wheel actuator configured to engage a steering rack, and a controller in electrical communication with the hand wheel actuator, the steering angle sensor, and the road wheel actuator. The controller is configured to identify movement of a hand wheel actuator mechanically coupled to the steering column with a steering angle sensor and determine an acceleration of the hand wheel actuator. The controller is also configured to determine an acceleration of a road wheel actuator configured to engage the steering rack for selectively changing a wheel angle and increase a steering ratio of the steer-by-wire system when the acceleration of the road wheel actuator is above a predetermined threshold value.
