Embodiment Construction
[0017] Below, refer to Figure 1-Figure 4 , the first embodiment of the hybrid power device of the present invention will be described. In this first embodiment, the control system of the hybrid power plant of the present invention is applied to figure 1 Shown is an automatic transmission TM with 6 forward speeds and 1 reverse speed.
[0018] This automatic transmission TM is a dual-clutch type. In the transmission case H, the first input shaft 13a and the second input shaft 13b, which are arranged parallel to each other and are supported so as to be freely rotatable, pass through the first friction clutch C1 and the second friction clutch C2, respectively. , is connected with the output shaft 10a of the engine 10 . The input member of the first friction clutch C1 is coupled to the support shaft 11d of the driven gear 11b, and the drive gear 11a that rotates integrally with the output shaft 10a of the engine 10 meshes with the driven gear 11b. Similarly, the input member o...

A first input shaft that transmits the driving force of the engine through a first friction clutch and a second input shaft that transmits the driving force of the engine through a second friction clutch are installed on the first input shaft and the second input shaft, respectively. The first gear transmission mechanism and the second gear transmission mechanism, and the final output shaft connected to the output shafts of the two gear transmission mechanisms, and the first input shaft or the second input shaft is connected to the motor generator In the hybrid power device, when the detected temperature of lubricating oil contained in the transmission is lower than a predetermined lower limit value, a shift stage of the gear train is selected to use the first gear transmission mechanism or the second gear transmission mechanism to transfer to The final output shaft transmits a torque larger than the required torque. In this state, the motor generator is operated as an electric motor, and then the first friction clutch or the second friction clutch is engaged, and by using the second The gear train of the shift speed selected by the 2-gear transmission mechanism or the 1st gear transmission mechanism transmits the driving force of the said engine to the said final output shaft.
Description
technical field [0001] The present invention relates to a hybrid device for a vehicle, and more particularly, to a hybrid device suitable for a dual-clutch type vehicle transmission in which the temperature of the lubricating oil contained in the transmission is rapidly raised when the lubricating oil is at a low temperature control system. Background technique [0002] Japanese Patent Application Laid-Open No. 2005-186931 discloses a hybrid device employing such a dual clutch. The hybrid device has a first input shaft and a second input shaft which are coaxially arranged and can rotate relative to each other and selectively transmit the driving force of the engine through a dual clutch, and are respectively installed on the first output shaft arranged in parallel with the two input shafts. The first gear transmission mechanism and the second gear transmission mechanism on the shaft and the second output shaft, and the driving wheel connected to the second output shaft and ...
