Abstract
A steering control system is provided for a vehicle with a steered wheel. The vehicle includes a control member that maneuvers within a range between leftward and rightward stops, and that delivers a requested steering signal. The steering control system includes: an actuator that acts on a steering angle of a steered wheel, and a controller that determines a control angle for controlling the actuator to steer the vehicle. The controller includes: a first unit that determines, according to the vehicle's speed and a parameter characteristic of the vehicle's equilibrium, a maximum steering angle on a steered wheel of an equivalent bicycle model of the vehicle, a second unit that determines a gearing-down ratio according to the range of the control member and the maximum steering angle, and a third unit that determines a steering angle according to the gearing-down ratio and the requested steering signal.
