What are the benefits of rear-wheel steering and how is it controlled?

Rear-wheel steering improves both low-speed maneuverability and high-speed stability. At low speeds, rear wheels turn opposite to fronts, reducing turning radius by up to 20%. At high speeds, rear wheels turn in the same direction as fronts, improving stability during lane changes and providing virtual wheelbase extension. Control strategies use vehicle speed, steering angle, and yaw rate inputs. The typical angle range is +/-5 degrees. Benefits include reduced parking effort, improved agility, and enhanced stability.
