Abstract
A rumble-strip following system for automated vehicle steering includes a vibration-detector, a steering-device, and a controller-circuit. The vibration-detector is configured to detect vibration experienced by a host-vehicle traveling a roadway. The steering-device is configured to steer the host-vehicle. The controller-circuit is in communication with the vibration-detector and the steering-device. The controller-circuit is configured to determine that the vibration is indicative of a tire of the host-vehicle contacting a rumble-strip arranged parallel to a heading of the roadway, and operate the steering-device so the tire follows the rumble-strip.
