The invention discloses an electric power-assisted steering controller in a square-box shape. The electric power-assisted steering controller comprises a PCB, a base and a cover board, wherein tapered supporting columns and a heat conducting seat are integrally formed on the base; the PCB is placed on the tapered supporting columns, positioned through two positioning columns penetrating through the PCB, and is fixed on the heat conducting seat through screws in a combining manner; the two positioning columns have different cross sections; the base and the cover board are pressed together; mounting bulges are inserted in corresponding mounting notches; the tapered supporting columns are positioned in the cover board, and the cover board and the base are buckled more and more tightly through the tapered supporting columns; four circular columns which are distributed in a rectangular shape and extend upwards are integrally formed on the base; a plurality of thread mounting blind holes corresponding to the the circular columns in position are formed in the back of the base, wherein the number of the thread mounting blind holes is the same as that of the circular columns. Through the adoption of the structure, the phenomena that the base and the cover board slightly swing after being mounted, the PCB and the base slightly swing after being mounted can be effectively avoided, and the problem that the local temperature of the PCB is too high is solved; the PCB can be prevented from being arranged inversely in the fore-and-aft direction; the electric power-assisted steering controller has a dust preventing effect.
