The invention discloses an automatic exhaust method and device for a hydraulic braking system, and the method comprises the steps: obtaining hydraulic braking parameters, collected by a first sensor, in the hydraulic braking system in response to a detected first event; a theoretical pressure intensity value corresponding to the braking stroke is obtained, and when it is determined that the difference value between the braking pressure intensity and the theoretical pressure intensity value exceeds a first set threshold value, a pressure relief instruction is sent to a pressure relief execution mechanism; when the pressure relief component generates relative motion relative to the hydraulic load, the second sensor is triggered to detect substances discharged by the pressure relief part, and a detection result is obtained; when it is determined that the discharged substance is brake fluid and the pressure reaches a set value, a recovery instruction is sent to a pressure relief executing mechanism; the pressure relief executing mechanism can respond to the recovery instruction to control the pressure relief component to generate relative motion relative to the hydraulic load, so that the pressure relief component is fixedly connected with the hydraulic load, and the hydraulic braking system recovers the braking capacity based on the hydraulic load. The braking effect of the vehicle is guaranteed, and braking failure is avoided.
