A study of a pressure regulator for an anti-lock braking system for low-powered vehicles

Abstract

This study proposes an innovative design of a hydraulic pressure regulator for an anti-lock braking system, called EconABS, for extremely low-powered vehicles. This system utilizes the braking force generated at the caliper as the energizing force to reduce the pressure in the caliper and to prevent over-braking. This approach limits power consumption and means that only minimal electric power is manipulated to supply the electric circuit and logic valve. The mathematical model is derived and the operating performance is simulated. Experimental results for the static situation are retrieved using a test rig. The experimental results represent consistency with the simulations as the design parameters are modified. The regulator design is shown to be a feasible solution for extremely low-powered vehicles.
