The invention discloses an electric hydraulic power steering system for a vehicle. The system comprises a steering oil tank, an electric hydraulic steering pump, a hydraulic power-assisted braking device and an electro-hydraulic steering gear which are communicated through a hydraulic pipeline, and an electro-hydraulic controller. An oil outlet of the steering oil tank is connected with an oil inlet of the electric hydraulic steering pump; an oil outlet of the electric hydraulic steering pump is connected with an oil inlet of the hydraulic power-assisted braking device; an oil outlet of the hydraulic power-assisted braking device is connected with an oil inlet of the electro-hydraulic steering gear; an oil return port of the hydraulic power-assisted braking device is connected with a firstoil return port of the steering oil tank; an oil return port of the electro-hydraulic steering gear is connected with a second oil return port of the steering oil tank; and the electro-hydraulic steering gear is connected with the electro-hydraulic controller. The system is convenient to arrange and high in system integration degree, the arrangement space of the whole vehicle is saved, the cost is reduced, and meanwhile the stability of a steering system and a braking system is improved.
