The invention discloses a self-powered type vehicle active suspension which comprises an actuator, a spring, a power module circuit, a super capacitor and a controller; the actuator and the spring are arranged between a vehicle body and a vehicle bridge in parallel; the input end of the controller is connected with a sprung mass speed sensor and an unsprung mass speed sensor; the actuator is composed of a piston barrel, a linear motor unit, a variable damping unit, an upper lifting lug, a lower lifting lug, a piston barrel upper end cover and a piston barrel lower end cover; the linear motor unit is composed of a piston rod and a plurality of permanent magnets; a partition plate is arranged in the piston barrel; a plurality of silicon steel sheets and a plurality of primary windings are arranged in the piston barrel between the piston barrel upper end cover and the partition plate; the variable damping unit is composed of a piston and a damping liquid channel; and a plurality of proportional electromagnetic valves are arranged on the damping liquid channel. The invention also discloses a coordinated control method of the self-powered type vehicle active suspension. The self-powered type vehicle active suspension is high in working stability, reliability, energy reclaiming efficiency and real time and can be in the optimal vibration attenuation state.
