The invention discloses an automotive power steering electric controller for preventing a cover plate or a PCB from being placed reversely. The automotive power steering electric controller comprises the PCB, a base and the cover plate. Conical supporting columns and a heat conduction seat in the shape of a right trapezoid are integrally formed above the base. The PCB is arranged on the conical supporting columns and located through two locating columns penetrating the PCB, and the PCB is fixed to the heat conduction seat by being combined with screws. The cross sections of the two locating columns are different. Mounting notches are arranged in the left side of the base, and mounting protrusions are arranged on the left side wall and the right side wall of the cover plate. The base and the cover plate are arranged together in a pressed manner. The mounting protrusions are inserted in the corresponding mounting notches, and the conical supporting columns are located in the cover plate, so that the cover plate and the base are buckled more and more tightly. A triangular misloading prevention mark is arranged at the position, close to the right rear corner, of the top of the cover plate, and a plurality of strip-shaped heat conduction grooves extending left and right are formed in the back face of the base. The problems that the base and the cover plate slightly shake after being mounted, the PCB and the base slightly shake after being mounted, and the local temperature of the PCB is too high are effectively solved, and the PCB or the cover plate is prevented from being placed reversely in the front-back direction.
