摘要： The advantage of the theoretically correct Ackerman steering of land vehicles is well documented in the literature. Steering forces, vehicle handling, and tire wear are greatly improved by having correct toe angles of all steerable wheels. Adjustements in the suspension system and steering apparatus at the factory only provide first-order corrections to toe angles. A process for actively adjusting toe angles during operation of the vehicle is disclosed in this invention. Vehicle dynamics measuring devices to sense vehicle motion or position steering devices to measure toe angles are used in this process. Secondary toe angle corrections can be actively provided to account for inherent toe angle changes during maneuvers of the vehicle. An aftermarket apparatus for actively adjusting the toe angle is an embodiment of this invention. One such device includes a mechanical screw actuator apparatus, a microstepping motor with optical encoder, computer with control strategy chip and a toe angle sensing device or an onboard dynamics computer. This apparatus can be used on all land vehicles and is especially useful for modifying existing truck and bus steering systems.
