The invention discloses a one-time assembled electric power-assisted steering controller for vehicles. 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 trapezoid 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 fixed on the heat conducting seat by screws in a combining manner; the base and the cover board are mounted together in a pressing manner; the tapered supporting columns are positioned in the cover board, and the cover board and the base are fastened more and more tightly; a round anti-misassembly label is arranged at a position which is close to the left front corner, at the top of the cover board; a plurality of bar-shaped heat conducting grooves extending left and right are formed in the back of the base. According to the electric power-assisted steering controller, the slight swing between the base and the cover board, as well as the slight swing between the PCB and the base after the base, the cover board and the PCB are mounted can be effectively avoided, and the problem that the local temperature of the PCB is too high is solved; the cover board is prevented from being arranged inversely, and one-time assembly is realized.
