Abstract
A vehicle implements a steering anti-catch (SAC) algorithm that reduces a superimposition angle added to the steering wheel angle in order to reduce occurrence of steering catch. The superimposition angle may be determined according to an AFS system. The reduction of the superimposition angle according to the SAC algorithm is amplified when the driver is steering away from a center position, the vehicle speed is below a threshold, and a voltage for powering the power steering system is below a threshold. The amount by which the superimposition angle is reduced may be limited to a maximum reduction and may be subject to a limit in its rate of change as well.
