CLUTCH CONTROL DEVICE FOR HYDRAULICALLY DRIVEN VEHICLE

摘要

A first motor 3 and a second motor 4 of variable displacement type are in parallel to each other connected to a hydraulic pump 2 in a closed circuit, through which the output torque from the first motor 3 is transmitted to an output shaft 6. A clutch control unit 10 controls a clutch device 15 as: when the engine speed is N1, which is the case where the accelerator pedal is fully depressed, the clutch is disengaged at the vehicle speed v1. When the engine speed is N3 (< N1), which is the case where the accelerator pedal is half depressed, the clutch is disengaged at the vehicle speed v3(< v1).
