摘要： To provide a traveling control mechanism and a traveling control method capable of controlling a traveling mechanism taking into consideration operation contents of a remote control valve. The problem is solved by a traveling control mechanism comprising a remote control valve (21, 22, 23, 24), a pressure adjusting solenoid valve (61, 62), a setting mechanism (70), and a controller (60). The traveling mechanism (8) allows a traveling speed to be switched between a high speed and a low speed in accordance with an operation amount of the remote control valve (21, 22, 23, 24). An HST circuit (30) is provided with a pump (31, 32) and a traveling motor (33), the pump (31, 32) connects to a pilot line (41, 42, 43, 44) allowing a hydraulic oil supplied from the remote control valve (21, 22, 23, 24) to flow therethrough, a pressure sensor (45) is attached to the pilot line (41, 42, 43, 44), and a rotation sensor (65) is attached to the traveling motor (33). The controller (60) controls a pressure of the hydraulic oil supplied from the remote control valve (21, 22, 23, 24) independently of a manual operation of the remote control valve (21, 22, 23, 24), on the basis of a setting signal, a pressure signal, and a rotation speed signal. The remote control valve (21, 22, 23, 24) controls a flow rate of the hydraulic oil discharged from the pump (31, 32) by changing or keeping constant the pressure inside the pilot line (41, 42, 43, 44).
