1. A vehicle vibration method with a vibration device that causes at least one wheel of a test target vehicle to vibrate in a front-rear direction and an up-down direction by sandwiching the wheel by a front shaft and a rear shaft extending in a left-right direction and causing at least one selected from the front shaft and the rear shaft to move back and forth in a horizontal direction, the method comprising:
an initial height setting step including setting a distance in the front-rear direction between the front shaft and the rear shaft to a predetermined initial setting distance and setting the wheel at a predetermined initial setting height;
a vibration step including performing vibration such that a tilt angle of the test target vehicle changes to simulate driving on a rough road by at least one selected from a raising operation step including narrowing the distance in the front-rear direction between the front shaft and the rear shaft from the initial setting distance to raise the wheel from the initial setting height, and a lowering operation step including widening the distance in the front-rear direction between the front shaft and the rear shaft from the initial setting distance to lower the wheel from the initial setting height; and
a return step including setting back the distance in the front-rear direction between the front shaft and the rear shaft to the initial setting distance.
