DRIVE SYSTEM CONTROL DEVICE FOR WORKING VEHICLE |
摘要 |
In a working vehicle, it is possible to achieve a downsizing of an engine by securing an output torque in a low rotating region of the engine without using any supercharger. In the working vehicle having the engine mounted to a travel machine body, a common rail type fuel injection device which injects fuel to the engine, and a continuously variable transmission which shifts power from the engine, a rotating speed N of the engine is limited to two kinds, N#1 and N#2. Further, a change gear ratio of the continuously variable transmission is changed and regulated in such a manner as not to change a vehicle speed of the travel machine body before and after changing the rotation speed N whichever of the two kinds N#1 and N#2 the rotating speed N of the engine is changed to. |
