The invention relates to the technical field of vehicle steering, and particularly discloses a steering control system and control method based on electric control pump closed-loop hydraulic pressure and a vehicle. The system comprises a first cavity and a second cavity which are formed in the two sides of a first piston in a first steering hydraulic cylinder; a third cavity and a fourth cavity are formed in the two sides of a second piston in a second steering hydraulic cylinder coaxial with the first steering hydraulic cylinder, one end of an electric control pump is communicated with the second cavity and the fourth cavity in a sealed mode through an oil pipe, and the other end of the electric control pump is communicated with the first cavity and the third cavity in a sealed mode. The electric control pump is in communication connection with the electric control steering wheel and the wheel rotating speed monitoring sensor; according to the system, the arrangement space of parts in the vehicle is saved, the structural layout of the system is more regular, simpler and modularized, the fault occurrence probability of the steering control system is reduced, meanwhile, the leakage flow loss and throttling loss of a traditional hydraulic steering system are solved, and the reliability of the system is improved. And the idle speed energy consumption of a traditional steering pump is reduced.
