The invention discloses a real-time monitoring method and device for the working state of a steering system of an automatic driving engineering vehicle. The method comprises the steps that the value of an inlet pressure sensor Pin is recorded as P0 under the condition that a steering pump works normally and steering does not act; respectively fitting a relation interpolation table Pin (x) of different steering rates x and inlet pressure of each type of vehicle; the invention discloses an automatic driving engineering vehicle. A controller obtains the current inlet pressure Pin value and the current steering rate x 'of the vehicle, and if the current inlet pressure Pin value is smaller than the P0 * per1 value of the vehicle of the same type or/and the current inlet pressure Pin value is smaller than the Pin (x') * per5 value, it is indicated that the working state of a steering hydraulic system of the vehicle is abnormal, the steering failure risk exists, and parking protection is needed. The working state of
