Abstract:
An antiskid braking control system comprising:a braking force generating means for generating braking force applied to a vehicle wheel; a braking force controlling means for controlling the braking force generated by the braking force generating means; and a wheel speed detecting means for detecting a rotational speed of a wheel, wherein a control parameter for the braking force controlling means is determined based upon at least the wheel speed detected by the wheel speed detecting means, and the braking force controlling means is, controlled in accordance with the determined control parameter,a steering factor detecting means for detecting at least one of steering factors including a steering torque and steering effort applied to a steering system extending from a steering wheel to a suspension of a vehicle; an aligning torque estimating means for estimating aligning torque produced on at least a wheel of the vehicle on the basis of the steering factor detected by the steering factor detecting means; a vehicle state variable detecting means for detecting a state variable of the vehicle; a wheel factor estimating means for estimating at least one of wheel factors including a side force and slip angle applied to the wheel on the basis of the state variable detected by the vehicle state variable detecting means; a grip factor estimating means for estimating a grip factor of at least a tire of the wheel, in accordance with a relationship between the alignment torque estimated by the aligning torque estimating means and the wheel factor estimated by the wheel factor estimation means; and a control parameter adjusting means for adjusting the control parameter based upon the grip factor estimated by the grip factor estimating means.
