Design Considerations of Adaptive Brake Control Systems

In this paper, some of the design aspects of adaptive brake control systems are studied, especially the interaction of the software with the hardware of the system. Two modes of operation of the brake pressure modulator have been considered; the software changes are effected to modify further the mode of operation of the system. The effect of the rate of rise of wheel cylinder pressure and the effect of rate of decay of pressure on the effectiveness and the maximum wheel slip in the first cycle have been studied. The hardware and the software are so modified as to give satisfactory performance of the wheel and the vehicle for four different forward speeds and for three different road conditions.
