Four-wheel steering improves maneuverability and stability on the highway while making low-speed parking and turning easier for the driver. With four-wheel steering, the rear wheels are controlled by an electronic system. At high speeds, the rear wheels are steered in the same direction as the front. The result: the car drives as if on rails as the system compensates for the lateral force exerted on the rear wheels that can cause a vehicle to sway or skid. Safety and performance are enhanced. At low speeds, the rear wheels are steered in the opposite direction from the front to reduce the vehicle’s turning circle making parallel parking a piece of cake.
Novotechnik position sensors at the driver’s wheel and the rear axle provide the high-resolution, multiple-redundant measurements necessary to implement four-wheel steering.
