The invention relates to an automobile stability parameter test bench and a test method using the same, which are used for integrally testing automobile mass parameters, centroid position parameters and anti-tipping angle parameters. The automobile stability parameter test bench of the invention comprises a measuring platform, four platform balances, platform supporting columns, a foundation, three hydraulic cylinders, an inclination angle measuring device, hydraulic sensors, a pump station and a computer, wherein the four platform balances are installed on the measuring platform and are supported by a weighting sensor; the supporting points of the platform supporting columns are distributed in rectangular peaks; the foundation is used for bearing the supporting columns and the platform; the three hydraulic cylinders are arranged between the platform and the foundation and can enable the platform to incline longitudinally or laterally; the inclination angle measuring device is fixed on the platform; the hydraulic sensors are installed in the positions of the upper cavity and the lower cavity of the two hydraulic cylinders which enable the platform to incline longitudinally; the pump station is connected with the hydraulic cylinders; and the computer is used for acquiring and calculating the data of the weighing sensor, the oil pressure of the hydraulic cylinders and the inclination angle data of the platform. Compared with the existing test equipment, the invention can finish tests of automobile total mass, axle loads, wheel loads, centroid positions, anti-tipping angles and the like, so that the test workload and the test cost of the parameter tests are greatly reduced.
