Abstract
The objective of the present invention is to present a reliable evaluation method for determining whether a moving vehicle is in a stable antiskid control operation or in an unstable antiskid control operation even when there are wheel speed pulsation caused, and a device based on such a method. In the antiskid control apparatuses and the methods of the invention, it is determined that the moving vehicle is in the stable control when the wheel acceleration being generated while the wheel speed is decreasing exceeds a predetermined threshold value, and also determined that the moving vehicle is in the unstable control when the wheel acceleration is below the threshold value. In another antiskid control apparatus and the method of the invention, it is determined that moving vehicle is in the unstable control or in the stable control basis on the changes in the wheel slipping rate with respect to the coefficient of friction between the wheel and a road.
