A Method of Control of Plural Autonomous Dump Trucks in Heavy Construction Sites

It is anticipated that autonomous dump trucks system could reduce approximate 30 % of the workers required at a heavy construction site (i.e., dam constructions, road constructions, etc.) in the future. The technologies required for an automatic dump truck are developed by using the test vehicle. On paved roads, the continuous driving distance that the unmanned driving control could achieve is 2 km at the maximum speed of 30 km/h. The difference between the planned path and the trajectory is within ±100 cm. This paper describes the communication function to control plural autonomous dump trucks in heavy construction sites. This system can control five autonomous dump trucks automatically in wide area by utilizing some radio station and cable communication.
