The invention relates to the technical field of automobiles, in particular to an automobile full-active suspension system and a vehicle, the automobile full-active suspension system comprises a shock absorber assembly, a hydraulic control oil way and an oil supply system, the shock absorber assembly comprises a first hydraulic cavity and a second hydraulic cavity, a piston push rod is arranged in the first hydraulic cavity, and an electromagnetic valve is arranged in the piston push rod; the electromagnetic valve controls whether the first hydraulic cavity is communicated with the second hydraulic cavity or not and controls the opening degree by adjusting the opening degree of a valve port of the electromagnetic valve; the hydraulic control oil way comprises an oil inlet way, a first oil return way and a second oil return way. The oil inlet way feeds oil into the first hydraulic cavity or the second hydraulic cavity through the pressure distribution valve. The first hydraulic cavity or the second hydraulic cavity returns oil through the pressure distribution valve, and the oil supply system is used for supplying oil to the oil inlet way and returning oil to the first oil return way and the second oil return way. According to the suspension, the rigidity and the damping of the suspension are dynamically and rapidly adjusted in a self-adaptive mode through mutual matching control of hydraulic pressure and the built-in electromagnetic valve, and the comfort and the stability of a vehicle in the running process are improved.
