The present invention provides an electric power steering controller and an electric power steering system that allow appropriate operation even when the operation of their torque sensors is abnormal. The controller 100 of a main microcomputer 1-1 outputs motor drive signals 3 to a drive circuit 5 based on first and second torque signals detected by a torque sensor 2 that detects steering force. The drive circuit 5 drives a motor 6 to generate assistive torque. A torque sensor abnormality detector 101 is installed within the main microcomputer 1-1 and detects abnormalities of the torque sensor 2 based on the first and second torque signals. An excessive torque detector 102 is installed within an external device 1-2 and outputs a motor stop signal when either of the first and second torque signals exceeds a given value.
