Abstract

A high reliability and low power consumption anti-lock brake system is disclosed. The two pilot valves are controlled so as not to be energized concurrently. The secondary battery of the anti-lock brake system is charged by a power supply and/or a generator. An electric double layer capacitor having a housing made of functionally graded aluminum ceramic material is used as the secondary battery.
