The invention discloses a semi-active control type hydraulic suspension and a vehicle having the same. The semi-active control type hydraulic suspension comprises a base, a rubber main spring, a bottom film, an upper baffle plate and a lower separation plate, a movable decoupling disc, an elastic decoupling film and a control valve, wherein the elastic decoupling film and the upper baffle plate or the lower separation plate divide an air chamber from an upper liquid chamber; the elastic decoupling film separates the air chamber from the rest part of the upper liquid chamber; an air hole is formed in the upper baffle plate or the lower separation plate for connecting the air chamber with atmosphere; and the control valve is used for controlling the communication and the separation of the air hole and the atmosphere. The semi-active control type hydraulic suspension is provided with the air chamber; through the communication and the separation of the air hole and the atmosphere, the semi-active control type hydraulic suspension generates no dynamic hardening phenomenon under high frequency, or prominently improves the dynamic hardening frequency, reduces the high-frequency dynamic stiffiness, can prominently attenuate the vehicle vibration under high-frequency excitation, reduces the in-vehicle vibration and the noise level, enhances the vibration isolating effect, and improves the sitting comfort.
