Handwheel damping control of active steering system |
摘要 |
An active front steering (AFS) system that provides hand-wheel damping. The AFS system includes a damping control sub-system that determines a hand-wheel angular velocity based on the rate of change of a hand-wheel angle signal. The damping control sub-system determines the damping control signal by multiplying the angular velocity of the hand-wheel angle signal with a control gain. The damping control signal is added to a steering signal from a variable gear ratio control sub-system to generate a steering command signal. The damping control sub-system sets to the damping control signal to zero if a signal from a vehicle stability enhancement sub-system is activated.
