Method of determining initial transmission calibration |
摘要 |
A process for learning the pressure and volume characteristics for a given torque-transmitting mechanism is established on the final assembly line wherein a powertrain incorporating the desired transmission learning is installed within a vehicle. During the test process, the vehicle speed is generally maintained at Idle and the vehicle shift mechanism is maintained in Park, thereby mechanically locking the transmission output shaft. The torque-transmitting mechanisms to be learned are then engaged and disengaged in a predetermined sequence and the volume of the torque-transmitting mechanisms and the pressure characteristics of the controlling solenoid are learned. |
