The invention relates to the technical field of suspension control methods, in particular to a vehicle intelligent suspension variable rigidity and variable damping switching control method under an impact working condition, which comprises the steps of building an impact working condition database, acquiring vehicle real-time information, identifying a driving working condition and controlling variable rigidity and variable damping. Corresponding controllers can be selected according to different impact working conditions to perform variable-stiffness variable-damping switching control, so that the reduction efficiency of response acceleration is improved, and the time for the vehicle to reach the stability is shortened; and a variable-stiffness variable-damping switching control system under the magnetorheological-air suspension impact working condition is built according to the variable-stiffness variable-damping switching control method for the vehicle intelligent suspension under the impact working condition. The method has the effects of effectively attenuating the response acceleration of the vehicle, enabling the vehicle to quickly reach a stable state and improving the riding comfort.
