1. An electric brake booster for an autonomous vehicle having a dual actuator, comprising:
a body part configured to receive a power cylinder for generating braking pressure in an autonomous driving/braking mode;
a driving shaft movable in an axial direction in the power cylinder and coupled to a piston;
a first motor connected to a first side of the driving shaft and configured to provide driving power to the driving shaft;
a second motor connected to a second side of the driving shaft and configured to provide driving power to the driving shaft in a direction equal to a direction of the driving power provided from the first motor; and
a controller configured to determine whether the first motor or the second motor operates normally and to simultaneously or separately operate the first motor and the second motor based on a magnitude of the pressure in the power cylinder or on whether emergency braking occurs;
wherein any one of the first motor and the second motor has a hollow structure to receive the piston therein and move the piston.
