Vehicle vibration method and vehicle vibration device

Abstract

A vehicle vibration method suitable for performing a test simulating a rough road, the vehicle vibration method using a vibration device that causes at least one wheel of a test target vehicle, the method including: an initial height setting step including setting a shaft distance in the front-rear direction between a front shaft and a rear shaft to an initial setting distance and setting the wheel at an initial setting height; a vibration step including performing vibration by at least one selected from a raising operation step including narrowing the shaft distance from the initial setting distance to raise the wheel from the initial setting height, and a lowering operation step including widening the shaft distance from the initial setting distance to lower the wheel from the initial setting height; and a return step including setting back the shaft distance to the initial setting distance.
