Charge controller

The power transmission mechanism reliably starts an internal combustion engine that is stopped during travel of a vehicle. While the internal combustion engine is stopped and the internal combustion engine and the transmission are disengaged by the main clutch, it is determined whether the mode is the EV travel mode, corresponding to the driving mode by the electric motor. In the case of the motor driving mode, and if the vehicle speed is less than a predetermined value, the engine is started in a neutral mode. If the vehicle speed is higher than a predetermined value, the engine is started in a standby mode. When starting in the standby mode, a gear set is selected based on the vehicle speed, and the input shaft and the output shaft are engaged.

Power transmission mechanism

The present invention is made to operate auxiliary machine while an engine is stopped, to start an engine and to charge a battery by providing a single motor and a simple construction and by providing a simple control operation. An engine system comprises an engine, a motor, and auxiliary machine, and further comprises a planetary mechanism having three elements comprising a sun gear, a carrier and a ring gear, to which any one of an output shaft of the engine, an output shaft of the motor and a drive shaft of the auxiliary machine are respectively connected, a uniting connection device capable of uniting two or more elements of the planetary mechanism, and a rotation direction restriction device which restricts a rotation direction of the drive shaft of the auxiliary machine to one direction.

Engine system, operating method therefor, and engine starting apparatus

In a hybrid vehicle control system equipped with an internal combustion engine ( ), an electric motor ( ) connected to the engine through a hydraulic clutch ( ) and an automatic transmission ( ) connected to the motor to be inputted with an output torque outputted from the engine and the motor to transmit the same to driven wheels ( ) of the vehicle, the output torque of the motor (TM) and supply of hydraulic pressure to the clutch (PCL) is increased until the determined speed difference (dN) is less than a threshold value (dN ) and then the output torque of the engine is reduced such that the engine speed (NE) is synchronized with the motor speed (NM) when the speed difference (dN) becomes less than the predetermined value (dN ), while increasing the supply of hydraulic pressure to a line pressure equivalent value. With this, it can effectively reduces shock at clutch engagement during switchover from electric motor-powered driving to internal combustion engine-powered driving.
