Embodiment Construction

[0020] FIG. 1 is a block diagram showing the structure of a hybrid vehicle according to an embodiment of the present invention. The output shaft of the internal combustion engine 1 is directly connected to the input shaft of the hydraulic torque converter 2 . The output shaft of the hydraulic torque converter 2 is fixedly connected to the input shaft of the multi-stage transmission 3 via a coupling unit 9 . The multi-stage transmission 3 includes an actuator 31 for mechanically controlling the shift-combination of the multi-stage transmission 3, and a transmission control circuit 32 for electrically controlling the actuator. The transmission control circuit 32 includes an program control circuit (ECU).

[0021] The transmission control circuit 32 determines the optimal gear ratio of the multi-stage transmission according to input information including vehicle speed, engine speed, accelerator pedal operation information and the like. The actuator 31 mechanically controls the ...

Abstract

A rotary shaft of a motor-generator of a hybrid-powered vehicle is connected to an output shaft of a torque converter (2) connected to an output shaft of an internal combustion engine (1). A control of acceleration or deceleration of the vehicle is assisted by controlling the motor-generator as a motor or a generator during a time period in which a slip occurs in the torque converter with a speed change control.

Description

technical field [0001] The invention relates to a hybrid vehicle equipped with an internal combustion engine and a motor-generator. The present invention relates to a technique for realizing a hybrid vehicle in which an internal combustion engine and a motor-generator are mounted as power sources on a vehicle having a power transmission system including a torque converter and a multi-stage transmission. The present invention relates to improving the driving performance of a hybrid vehicle and reducing energy loss due to the vehicle's torque converter. Background technique [0002] In order to effectively utilize the torque of the vehicle's internal combustion engine as its power source over a wide speed range, a transmission is provided between the power source and the axle. In addition, cars with automatic transmissions that do not require a clutch pedal to change gears while driving are becoming more and more popular, and almost all drivers today are familiar with such au...
