Patent ID: 7285927

Claim:
A control apparatus for an electro mechanical brake for generating a thrust force by causing an electric motor, controlled by an inverter, to push brake pads against a brake disk, said control apparatus comprising: switching means for selectively switching a power supply line of said inverter to a ground line, said switching means being inserted between said inverter and a power source; power consumption means inserted between said switching means and said ground line; and thrust force detecting means for detecting a thrust force applied to said brake pads; wherein, a feedback control is performed for the thrust force detected with said thrust force detecting means; said switching means is closed upon occurrence of an abnormal state in which a control deviation of the feedback control equals or exceeds a predetermined value; said inverter is of a microcomputer control type; and two microcomputers execute the same calculation process, and if calculation results by two microcomputers are not coincident, said switching means is closed.
