METHOD AND APPARATUS FOR CONTROLLING A MULTI-MODE POWERTRAIN SYSTEM |
| 摘要 |
A multi-mode powertrain system includes a transmission configured to transfer torque among an internal combustion engine, torque machines and an output member. A method for controlling the powertrain system includes operating the multi-mode powertrain system to execute an engine intake manifold pump down mode, and aborting the engine intake manifold pump down mode and fueling the engine, wherein aborting is based upon intake manifold pressure and system constraints. |
