| 发明名称 | Step-ratio transmission control for a hybrid vehicle | ||
| 摘要 | A parallel hybrid electric vehicle discrete step-ratio automatic transmission shift strategy attempts to cause a speed of a motor to approach a target motor speed to increase fuel economy for a coupled engine when in hybrid mode. A controller shifts the transmission according to a magnitude of a driver torque demand, the current rotor or impeller speed, and whether the motor is consuming or producing current. | ||

| 主权项 | 1. A parallel hybrid powertrain comprising: an automatic transmission capable of shifting between predetermined gear ratios; an engine coupled with the transmission; a motor including a rotor coupled with the engine; and a controller programmed to shift the gear ratio of the transmission to cause a speed of the rotor to approach a target rotor speed selected according to a magnitude of a driver torque demand and whether the motor is consuming or producing current. | ||
