    摘要: In a working vehicle 141, there is dissolved a risk that a black smoke is discharged, a knocking is generated and an engine stall is caused, if a lot of load is applied to a rotary tiller 24 during various works while traveling at a low speed. In the working vehicle 141 provided with an engine 70 which is mounted to a travel machine body 142, a common rail type fuel injection device 117 which injects fuel to the engine 70, and a continuously variable transmission 159 which shifts power from the engine 70, an engine driving point Q (Q1→Q2) relating to a rotating speed N and a torque T of the engine 70 is changed in such a manner that the rotation speed come to a high speed side rotating speed N2 dissolving an overload, and a change gear ratio of the continuously variable transmission 159 is modified and regulates in such a manner that a vehicle speed V of the travel machine body 142 does not change in the case that the overload acts on the engine 70 of having a low speed N1 in the rotating speed N.

    摘要: A hydraulic transmission (21) has an electric actuator (86) for changing its output/input rotation speed ratio. A controller 90 of the actuator memorizes a command current value to the actuator supposing that load is not applied on the hydraulic transmission, and calculates a value of load applied on the hydraulic transmission by calculating a difference between an actual command current value to the actuator and the memorized command current value. A command current value is compensated based on the value of load, and the actuator receives feedback to be controlled. A vehicle may have a differential mechanism (10), which combines rotation powers on input side and output side of the hydraulic transmission. A detector (82) detects rotation speed of a main speed change output shaft (27) serving as an output shaft of the differential mechanism. If the detected rotation speed differs from target rotation speed of the shaft (27) determined based on operation of a speed change operation tool, the actuator is forcedly controlled. This difference is supposed to be caused by load applied on the hydraulic transmission, whereby the load is calculated.
