1. A vehicle test apparatus comprising: a test article installation vehicle body to which four axles corresponding to four wheels that are a left front wheel, a right front wheel, a left rear wheel and a right rear wheel are attached, and on which a test article is installed;a first motion base that supports the test article installation vehicle body, and that allows the test article installation vehicle body to make motions of six degrees of freedom;four second motion bases each of which supports a corresponding one of the axles, and each of which allows a corresponding one of the axles to make motions of six degrees of freedom; andfour electric motors that are connected to outer end portions of the respective axles, and that apply torques to the respective axles, whereineach of the motion bases includes a stationary base, a movable base disposed above the stationary base, and an actuator that is disposed between and connected to the stationary base and the movable base, and that allows the movable base to make motions of six degrees of freedom,the test article installation vehicle body is disposed on the movable base of the first motion base and fixed to the movable base of the first motion base, andthe axles are supported by the corresponding movable bases of the second motion bases via motor bodies of the electric motors to which the corresponding axles are connected. 2. A vehicle test system comprising: the vehicle test apparatus according to claim 1; anda control unit that controls the motion bases. 3. The vehicle test system according to claim 2, wherein the control unit comprises:a position and posture target value generator that generates target values of a position and a posture to be taken by each of the motion bases, for each of the motion bases; anda controller that controls each of the motion bases so as to cause a position and a posture of each of the motion bases to coincide with the target values of the position and the posture generated by the position and posture target value generator. 4. The vehicle test system according to claim 2, wherein the control unit comprises:a detector that detects forces of respective six degrees of freedom generated by each of the motion bases;a force target value generator that generates, for each of the motion bases, target values of forces of respective six degrees of freedom to be generated by each of the motion bases; anda controller that controls each of the motion bases so as to cause the forces of respective six degrees of freedom detected by the detector, to coincide with the target values of forces generated by the force target value generator. 5. A vehicle test system comprising: a vehicle test apparatus; anda control unit, whereinthe vehicle test apparatus comprises:a test article installation vehicle body to which four axles corresponding to four wheels that are a left front wheel, a right front wheel, a left rear wheel and a right rear wheel are attached, and on which a test article is installed;a first motion base that supports the test article installation vehicle body, and that allows the test article installation vehicle body to make motions of six degrees of freedom; andfour second motion bases each of which supports a corresponding one of the axles, and each of which allows a corresponding one of the axles to make motions of six degrees of freedom, andthe control unit controls the motion bases and comprises:a position and posture target value generator that generates target values of a position ad a posture to be taken by each of the motion bases, for each of the motion bases; anda controller that controls each of the motion bases so as to cause a position ad a posture of each of the motion bases to coincide with the target values of the position and the posture generated by the position and posture target value generator. 6. A vehicle test system comprising: a vehicle test apparatus; anda control unit, whereinthe vehicle test apparatus comprises:a test article installation vehicle body to which four axles corresponding to four wheels that are a left front wheel, a right front wheel, a left rear wheel and a right rear wheel are attached, and on which a test article is installed;a first motion base that supports the test article installation vehicle body, and that allows the test article installation vehicle body to make motions of six degrees of freedom; andfour second motion bases each of which supports a corresponding one of the axles, and each of which allows a corresponding one of the axles to make motions of six degrees of freedom, andthe control unit controls the motion bases and comprises:a detector that detects forces of respective six degrees of freedom generated by each of the motion bases;a force target value generator that generates, for each of the motion bases, target values of forces of respective six degrees of freedom to be generated by each of the motion bases; anda controller that controls each of the motion bases so as to cause the forces of respective six degrees of freedom detected by the detector, to coincide with the target values of forces generated by the force target value generator.
