Abstract
It is necessary to be able to carry a load to any kind of place by transportation vehicle safely. For that purpose load-carrying platform horizontal level-keeping performance is significant on a transportation vehicle. However, a vehicle does not have a platform level-keeping function generally. Such a vehicle needs to have enough traveling performance also. Therefore it is aimed that the stability of the load-carrying platform on level-keeping. We confirm the performance with an experiment machine that has leveling control with the signal of the acceleration sensor in traveling.
