Abstract

PURPOSE:To prevent engine stall due to overload even in a working vehicle mounting a relatively small output engine by detecting the work load as a driving load and quickening response of deceleration control against increase of load. CONSTITUTION:A hydraulic pump 5 and a hydraulic driving motor 6 are coupled through a circulation oil path 18 constituted with pressure oil hose. A pressure sensor 7 for detecting hydraulic driving pressure of the hydraulic motor 6 is coupled to the circulation oil path 18. Signals from the pressure sensor 7 and a vehicle speed sensor 12 are fed to a controller 14 and compared each other, and deceleration control of a hydraulic pump 15 in a hydrostatic continuously variable transmission 3 is carried out through a motor 13 when increment of hydraulic driving pressure is detected such that the hydraulic driving pressure of a working device and driving speed satisfy a preset relation.
