The invention discloses a hydraulic integrated control system of a vehicle, and the vehicle. The hydraulic integrated control system of the vehicle comprises an oil tank, a parking brake, a braking hydraulic system, a parking braking switch, a pressure switch and a steering hydraulic system; the braking hydraulic system is in communication with the parking braking switch and the pressure switch; in the parking braking state, the braking hydraulic system supplies hydraulic oil to the steering hydraulic system; and in the parking braking release state, the braking hydraulic system supplies the hydraulic oil to the parking brake till the pressure switch detects the situation that the pressure of the parking brake reaches braking release pressure, and then the braking hydraulic system suppliesthe hydraulic oil to the steering hydraulic system. The hydraulic integrated control system of the vehicle integrates the steering function and the parking braking function and has the advantages ofbeing convenient to operate, good in parking braking effect, high in parking braking stability, good in ramp parking capacity, high in safe reliability, long in service life, simple in structure, lowin cost, small in size and the like.
