Problems solved by technology

[0009] However, in this case, since the driving force of the motor / generator output from the motor / generator output system cannot be utilized, the driving force transmitted to the driving wheels is insufficient, and there is a problem that the vehicle cannot start and accelerate properly.

Embodiment Construction

[0029] Embodiments of the present invention will be described below based on the drawings.

[0030] FIG. 1 is a configuration diagram of main parts of a hybrid vehicle 1 to which the present invention is applied. The output shaft of the diesel engine, that is, the engine 2 is connected to the input shaft of the clutch 4 . The output shaft of the clutch 4 passes through the rotating shaft of the permanent magnet synchronous motor / generator (hereinafter referred to as the motor / generator) 6 and the automatic transmission (hereinafter referred to as the transmission) with a 5-speed forward gear (hereinafter referred to as the gear) 8 input shaft connections. The output shaft of the transmission 8 is connected to left and right drive wheels 16 via a propeller shaft 10 , a differential device 12 , and a drive shaft 14 .

[0031] Therefore, when the clutch 4 is engaged, both the output shaft of the engine 2 and the rotation shaft of the motor / generator 6 can be mechanically connec...

Abstract

A hybrid electric vehicle is equipped with an engine output system that makes the engine generate a driving force and outputs the driving force of the engine and a motor output system that makes an electric motor generate a driving force and outputs the driving force of the electric motor, and is capable of transmitting to driving wheels the driving forces outputted from the respective systems. If a failure of the motor output system is not detected, a vehicle ECU sets the gear of an automatic transmission for start-up of the vehicle to a first gear. If the failure is detected, the vehicle ECU sets the gear of the automatic transmission for start-up the vehicle to a second gear that is lower than the first gear.

Description

technical field [0001] The present invention relates to a control device for a hybrid vehicle, and more particularly to a control device for a hybrid vehicle capable of separately transmitting driving force of an engine and driving force of a motor / generator to drive wheels of the vehicle. Background technique [0002] Currently, a hybrid vehicle is known that has: an engine output system that causes an engine to generate and output driving force; and a motor / generator output system that causes a motor / generator to generate and output driving force. As a type of such a hybrid vehicle, a so-called parallel hybrid vehicle capable of transmitting the driving force output by the above-mentioned two systems to the driving wheels of the vehicle is being developed and put into practical use. [0003] As such a parallel type hybrid vehicle, there is, for example, a hybrid vehicle proposed in Japanese Patent Laid-Open No. 5-176405 (hereinafter referred to as Patent Document 1), which...
