Problems solved by technology

[0004] In such a hybrid system, when the transmission is shifted, due to the inertial force caused by the rotating electric machine connected to the input shaft of the transmission, it takes time to synchronize the rotation, and the time required for the shift increases.

Embodiment Construction

[0012] exist figure 1 Among them, 1 is an engine, 2 is a gear type transmission, and a friction clutch 3 is installed between the output shaft of the engine 1 and the input shaft 2a of the transmission 2 .

[0013] As for the engine 1, a diesel engine or a CNG engine (an engine fueled by compressed natural gas) can be used. 4 is a rotating electric machine (motor generator), which functions as a generator and a motor. The input / output shaft 4a of the rotary electric machine 4 is connected to the input shaft 2a side of the transmission 2 via a rotation transmission mechanism 5 serving as a gearbox.

[0014] The transmission 2 is provided with a control unit 6 for controlling the shifting. Connect the control unit 6 to the shift lever device 7 and the hybrid electronic control unit 10 (hybrid ECU). Command the corresponding gear shift.

[0015] A propeller shaft is connected to the output shaft 2b of the transmission 2 to transmit driving force to the wheels.

Abstract

In a hybrid-drive electric vehicle, upon request of gear shifting of a transmission (2), a clutch (3) is first disconnected and the transmission (2) is set to a neutral position. The rotating electric generator 4 is then operated in a motor mode or a power generating mode so that a rotational speed of an input shaft of the transmission (2) reaches a region of a synchronizing rotational speed in accordance with a requested gear position. When the rotational speed of the input shaft of the transmission (2) reaches the region of the synchronizing rotational speed, the gear position of the transmission (2) is changed over from the neutral position to the requested gear position. Thus the rotation synchronizing time for the gear shifting in the transmission (2) is reduced, making it possible to perform the gear shifting for a short period of time.

Description

technical field [0001] In particular, the present invention relates to a speed change control device for a transmission in a vehicle that includes an engine and a rotating electric machine (motor generator) as a power source of the vehicle and includes a parallel type hybrid drive system. Background technique [0002] JP-A-10-304513 and JP-A-2001-103603 propose a hybrid system including an engine and an electric motor for driving a vehicle. [0003] In addition, there is known a system in which a clutch is installed between an engine and a transmission, and a rotating electric machine that functions as a motor and a generator is connected to an input side of the transmission. [0004] In such a hybrid system, when the transmission is shifted, the inertial force caused by the rotating electric machine connected to the input shaft of the transmission acts, so rotation synchronization takes time, and the time required for the shift increases.
