The invention discloses an electric power steering controller for an automobile. The electric power steering controller comprises a printed circuit board (PCB), a base and a cover plate. Tapered support columns and a heat-conducting seat are integrally formed on the base. The PCB is disposed on the tapered support columns and located through two locating columns penetrating through the PCB, and the PCB is fixed to the heat-conducting seat by the combination with screws. The base and the cover plate are arranged together in a press fit mode. Mounting protrusions are inserted into corresponding mounting notches, the tapered support columns are disposed in the cover plate, the cover plate and the base are made to be fastened tighter and tighter, and a circular mistaken-mounting prevention mark is arranged at the position, close to the front left corner, of the top of the cover plate. Four cylinders which extend upwards and are distributed in a rectangular shape are integrally formed on the base, and threaded mounting blind holes with the number identical to the number of the cylinders and the positions corresponding to the positions of the cylinders are formed in the back of the base. By means of the structure of the electric power steering controller, the problems of slight shaking between the base and the cover plate as well as between the PCB and the base after mounting, too high local temperature of the PCB and reverse disposing of the cover plate are effectively solved; besides, the dustproof effect is achieved.
