A vehicular powertrain includes an electro-mechanical transmission mechanically-operatively coupled to an internal combustion engine. A method for operating the powertrain includes monitoring operator inputs, monitoring a transmission output, and terminating an engine operating mode when a time-rate change in the transmission output exceeds a threshold absent a change in the monitored operator ...

A system and method of controlling a hybrid electric vehicle powertrain is provided. The hybrid-electric powertrain includes an engine, a battery, an electric motor, an electric generator and a transmission with a planetary gear unit. The planetary gear unit mechanically couples the engine, the electric motor and the electric generator to effect power delivery to vehicle traction wheels. Stored electrical power is delivering to the electric motor to drive the traction wheels in an electric-only ...

Inventors:  Miyazaki, Takeshige; TSUJIMURA, Manabu; Kamiya, Mitsutoshi

When a gear position at a higher speed range than a “specific gear position at a lower speed range” (e.g., first speed) is determined (when the torsional vibration is difficult to occur), a clutch torque is controlled such that a clutch is in a totally engagement state (a revolution speed Ne of an output shaft of an engine=revolution speed Ni of an input shaft of a transmission). On the other hand, when the “specific gear position at the lower speed range” (e.g., first speed) is ...

Boosted engine operation and spark timing of an engine may be adjusted with alcohol content of the fuel in a direct injection engine. Further, various adjustments may be performed in numerous related systems to account for increased maximum engine torque, such as traction control, transmission shifting, ...

In a hybrid vehicle having a locking mechanism in which a play elimination process is required in the locking, a torque shock in the play elimination is reduced. In a hybrid vehicle 1 having a locking mechanism 700 which is a cam-lock type engaging apparatus, an ECU 100 performs MG1 locking control. In the control, play is formed between a cam 710 and a clutch plate 720 of the locking mechanism 700. The formed play is gradually reduced such that ...
