20100022350 | VEHICLE WITH AN ENGINE AND AN AUTOMATIC TRANSMISSION - A vehicle is provided with an engine and an automatic transmission and a process for controlling an automatic transmission. In order to reduce the reaction time after a slight tip in of less than 50% during a closed throttle downshift, it is proposed to send a positive torque request to the engine at the beginning of the tip in on the accelerator. This is based on the idea to use a transmission positive torque request to force the engine to override its tip in torque management functions and provide a faster torque increase. This positive torque request at the beginning of the tip in improves considerably the engine response time. The vehicle reaction time when tipping in during a closed throttle downshift has been reduced by about 250 ms or 30%. | 01-28-2010 |
