The invention discloses an automobile automatic steering device equipped with an electronic control unit communicated with a CAN bus. The electronic control unit outputs a signal to a motor; the motor drives an electromagnetic clutch to complete steering actions; a steering wheel rotary angle transmitter outputs a steering wheel steering signal to the CAN bus; a microprocessor receives the steering signal of the steering wheel rotary angle transmitter via the CAN bus; the automobile automatic steering device is further provided with an electronic switch; an output end of the microprocessor is connected with an input end of a DA conversion chip; an output end of the DA conversion chip is connected with a normally-open end of the electronic switch; a COM port of the electronic switch is connected with an input end of a buffer; and the buffer outputs a signal to the electronic control unit. The automobile automatic steering device is an unmanned vehicle steering automatic control device based on an electric steering system; original vehicle resources can be fully utilized; and the automobile automatic steering device is advantaged by low development cost, simple joints, easy installation and debugging and convenient manual/automatic switching.
