Embodiment Construction

[0028] Embodiments of the power transmission control device for a vehicle according to the present invention will be described below with reference to the drawings.

[0029] (structure)

[0030] figure 1 A schematic configuration of a vehicle equipped with a power transmission control device (hereinafter referred to as "this device") according to an embodiment of the present invention is shown. This vehicle is a hybrid vehicle having an internal combustion engine and a motor generator as power sources and having a so-called electromechanical automatic transmission (AMT) using an active stage transmission and clutch.

[0031] This vehicle has an engine E / G, a transmission T / M, a clutch C / D, and a motor generator M / G. The E / G is one of known internal combustion engines, for example, a gasoline engine that uses gasoline as fuel, and a diesel engine that uses light oil as fuel.

[0032]An output shaft A1 of the engine E / G is configured to be driven and rotated by a starter mot...

Abstract

When the internal combustion engine driving torque (Te) is transmitted to the drive wheels and the vehicle is running, Te and the clutch torque (Tc) are reduced and the motor driving torque (Tm ) increases. Thereafter, when Tc becomes zero ( t2 ), an upshift operation is performed while maintaining Tc at zero and Tm is transmitted to the drive wheels ( t2 to t3 ). Thereafter, Te and Tc are increased and Tm is decreased (t3 to t5) according to the completion of the upshift operation (t3). During the period (t1 to t2) until Tc becomes zero after the upshift condition is established, the generator driven to rotate by the output shaft of the internal combustion engine generates a load torque (Ts). In a hybrid vehicle equipped with an AMT, it is possible to reduce power consumption associated with driving the motor when an upshift operation is performed with assistance from the driving torque of the motor.

Description

technical field [0001] The present invention relates to a power transmission control device for a vehicle, and particularly relates to a power transmission control device for a vehicle that is applicable to a vehicle having an internal combustion engine and an electric motor as power sources and a clutch. Background technique [0002] In recent years, a power transmission control device has been developed (for example, refer to Patent Document 1), which has: a stepped transmission having a plurality of shift speeds and not having a torque converter; a clutch inserted in the Between the output shaft of the internal combustion engine and the input shaft of the stepped transmission and can adjust the clutch torque (the maximum value of the torque that the clutch can transmit); the control mechanism that uses the actuator to control the clutch torque and The gears of the stepped transmission. This power transmission control device is also called an electromechanical automatic t...
