Abstract

Provided is a power transmission device with which it is possible to alleviate wasteful fuel consumption and prevent deterioration in the operating sensitivity of an actuator when restarting an engine. The power transmission device is provided with control devices (main controller (100) and ECU (101)) which, upon detecting that a console means (35) has not been operated for a prescribed time (non-operation adjudication threshold t1) or longer, shut off an engine (10), interrupt a clutch (15), and block the supply of power from a battery (60) to a motor generator (50); upon detecting thereafter that the console means (35) has been operated, activate the engine (10) with a cell motor (80) and allow the supply of power from the battery (60) to the motor generator (50); and after the RPMs (Ne) of the engine (10) reach or exceed a prescribed value (RPM Np), carry out an idling stop control, connecting the clutch (15) and blocking the supply of power from the battery (60) to the motor generator (50).

Description

technical field [0001] The present invention relates to technology of a power transmission device using an engine and an electric motor. Background technique [0002] Conventionally, technologies related to a power transmission device that automatically stops or starts an engine under predetermined conditions have been known. For example, as described in Patent Document 1. [0003] The power transmission device described in Patent Document 1 includes an engine as a power source, a hydraulic pump for discharging hydraulic fluid, a clutch interposed between an output shaft of the engine and an input shaft of the hydraulic pump, and an input shaft of the hydraulic pump. A connected electric motor (electric motor), a flywheel fixed to an input shaft of the electric motor, an actuator driven by hydraulic oil supplied from a hydraulic pump, and an operating member for operating the actuator. [0004] With near no load applied to the actuator, the clutch is disengaged, the engine...
