ROLLING COMPACTION MACHINE
To provide a rolling compaction machine capable of appropriately changing a deceleration degree when braking an airframe.SOLUTION: A rolling compaction machine comprises a compaction roller (3), a deceleration device (7) to decelerate an airframe, a speed sensor (31), a distance sensor (33) to detect an obstacle distance (L) from an obstacle located in a travel direction of the airframe, and a controller (40) to control the deceleration device. The controller includes a deceleration degree setting portion (51) to set the maximum deceleration (A1, A2, A3) of the airframe, a collision timing estimation portion (53) to estimate a collision timing (T1) when the airframe collides with the obstacle, and a deceleration controller (55) to control the deceleration device. The deceleration degree setting portion sets the maximum deceleration according to the road surface state. The collision timing estimation portion estimates the collision timing based on the speed of the airframe, obstacle distance and the maximum deceleration. The deceleration controller controls the deceleration device to decelerate the airframe at the maximum deceleration and stop the airframe by the collision timing.SELECTED DRAWING: Figure 4
