The invention discloses a magnetorheological semi-active suspension switching control system and method based on image recognition. The method comprises the steps that a monocular camera is adopted to shoot a road surface image in front of a vehicle in real time, and obstacle recognition is carried out through a pre-trained deep learning model; according to real-time vehicle speed data collected by the vehicle speed sensor, the controller matches control parameters adapting to the current vehicle speed and the obstacle type by using a control parameter switching rule table obtained through simulation in advance in combination with an obstacle recognition result; according to the control parameters and the control algorithm, the controller calculates expected current needed by the magnetorheological damper on the basis of vehicle dynamic data collected in real time; the current source outputs actual current to the magnetorheological damper according to the calculated expected current, and the damping force of the magnetorheological damper is changed by adjusting current input of the magnetorheological damper. According to the invention, real-time identification of front obstacles can be realized, the comfort and the stability of the suspension system under complex road conditions are improved through an optimized control strategy, and particularly, the vibration reduction performance is obviously improved when the suspension system passes through typical obstacles.
