METHOD OF CONTROLLING VEHICLE TORQUE |
| 摘要 |
In response to a transmission upshift command and a transmission element speed being greater than a threshold, a controller may reduce a rate of engine air intake prior to initial engagement of an oncoming shift element, at least until a target speed ratio is achieved. This reduction may reduce a transmission input torque such that upshift driveline disturbances are reduced. |

1. A method of controlling transmission input torque comprising:
in response to a transmission upshift command, a transmission element speed greater than a speed threshold, and a transmission input torque greater than a torque threshold, reducing a rate of engine air intake prior to initial engagement of an oncoming shift element at least until a target speed ratio is achieved to reduce the transmission input torque such that driveline disturbances associated with the upshift are reduced. |
