The invention discloses an electric power-assisted steering controller easy in forming. The electric power-assisted steering controller comprises a PCB, a base and a cover board, wherein tapered supporting columns and a heat conducting seat in a right-angled trapezium shape are integrally formed on the base; the PCB is arranged 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; 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; a plurality of bar-shaped heat conducting grooves extending to left and right are formed in the back of the base. Through the adoption of the electric power-assisted steering controller, the phenomena that the base and the cover board slightly swing after being mounted, the situation that 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 is easy in forming.
