The invention discloses an electric power steering torque controller. The electric power steering torque controller comprises a basic power module, a turning angle self-adjusting module and a power output module, wherein the basic power module obtains a present basic power torque according to present vehicle speed and a power characteristic curve; the turning angle self-adjusting module comprises an anticipant control torque unit, a comparing unit and a compensating unit; the anticipant control torque unit obtains a present anticipant control torque according to the present vehicle speed, a present steering wheel turning angle and an anticipant control torque table; the comparing module calculates and outputs a present deviation value; the present deviation value is a difference value between a present real-time detected control torque and the present anticipant control torque; the compensating module obtains a present compensating power torque according to the present vehicle speed, the present deviation value and a compensating torque table; the power output module outputs a present target power torque; and the present target power torque is the sum of the present basic power torque and the present compensating power torque. According to the electric power steering torque controller, the steering hand feel can be automatically adjusted along with a turning angle of a steering wheel.
