SYSTEM AND METHOD FOR CONTROLLING A TRANSMISSION |
| 摘要 |
The present invention provides a smoother driving experience through the use of an advanced powertrain system for a vehicle. The powertrain system includes a transmission having a gear selection controller adapted to select one of a plurality of gear ratios, an electronic control unit, at least one information acquisition unit wherein the electronic control unit uses information from the information acquisition unit to determine if the vehicle is stationary and if the vehicle is on an expressway. If the electronic control unit determines the vehicle is stationary and the vehicle is on an expressway, then the electronic control unit sends a signal to the gear selection controller of the transmission to select a lower gear ratio that would normally be used to transition the vehicle from a stationary to a moving state. |

1. A powertrain system for a vehicle comprising;
a transmission having a gear selection controller adaptive to select one of a plurality of gear ratios; an electronic control unit; at least one information acquisition unit; wherein the electronic control unit uses information from the information acquisition unit to determine when the vehicle is stationary and when the vehicle is on an expressway, when the electronic control unit determines the vehicle is stationary and the vehicle is on an expressway then the electronic control unit sends a signal to the gear selection controller of the transmission to select a lower gear ratio than would normally be used to transition the vehicle from a stationary to a moving state. |
