The invention discloses an automobile electric power steering device. The automobile electric power steering device consists of a lock body, a driving part assembly, a lock rod, a printed circuit board and a locking/unlocking sensing part, wherein one side of the lock body is open, and is provided with a lock hole; the printed circuit board and the driving part assembly are arranged in the lock body, and the lock rod is driven by the driving part assembly to move in a reciprocating way in the lock hole; the locking/unlocking sensing part is arranged on the edge of the printed circuit board, is in contact with a part of the locking/unlocking sensing part, and is used for sensing the steering column locking position and the steering column unlocking position of a locking rod according to the contact position change of the driving part assembly. By applying the automobile electric power steering device disclosed by the invention, the influence of a surrounding magnetic field on an electronic component is avoided from the source, the practical locking and unlocking states of a steering column can be sensed without any error through a physical measure for over 30, 000 times, the durability and reliability of a product are enhanced, and the assembly time is greatly shortened.
