Claim 0:
1. An apparatus for controlling an autonomous vehicle brake, comprising:
a first brake controller configured to control a brake module of an autonomous vehicle by receiving a deceleration command from an autonomous controller for controlling autonomous driving of the autonomous vehicle;
a second brake controller configured to control the brake module of the autonomous vehicle by receiving a deceleration command from the autonomous controller; and
a sensor unit configured to detect a driving state of the autonomous vehicle to transmit the detected driving state to each of the first and second brake controllers independently,
wherein:
the sensor unit comprises:
a first wheel speed sensor directly connected to the first brake controller for detecting a wheel speed of the autonomous vehicle to transmit the detected wheel speed to the first brake controller;
a second wheel speed sensor directly connected to the second brake controller for detecting a wheel speed of the autonomous vehicle to transmit the detected wheel speed to the second brake controller;
a first inertial measurement unit (IMU) for detecting inertia for at least one of acceleration, rotation, and inclination of the autonomous vehicle to transmit the detected inertial to the first and second brake controllers; and
a second IM U for detecting inertia for at least one of acceleration, rotation, and inclination of the autonomous vehicle to transmit the detected inertial only to the second brake controller to enable the second brake controller to maintain control of the brake module of the autonomous vehicle when an error occurs in the first brake controller; and

the first and second brake controllers are configured to exchange monitoring information with each other in a predetermined communication manner to monitor an operation state, so that control of the brake module is transferred according to the result of monitoring.
