APPARATUS FOR LEARN CONTROL OF AUTOMATIC TRANSMISSION AND METHOD THEREOF |
摘要 |
An apparatus for a learn control of an automatic transmission includes a storage unit configured to store an initial fill time value and a gain value corresponding to a revolution per minute (RPM) peak to peak of a turbine. An oil pressure applier is configured to apply an oil pressure to a non-operating friction element. An RPM measurer is configured to measure the RPM of the turbine, and a learn controller is configured to control the oil pressure applier to apply the oil pressure to the non-operating friction element during a preset reference time and control the initial fill time based on the RPM peak to peak of the turbine showing a difference between a measured value RPM of the turbine measured by the RPM measurer and a preset targeted value while a vehicle is in a coasting operation in an in gear state. |

1. An apparatus for a learn control of an automatic transmission, comprising:
a storage unit configured to store an initial fill time value and a gain value corresponding to a revolution per minute (RPM) peak to peak of a turbine; an oil pressure applier configured to apply an oil pressure to a non-operating friction element; an RPM measurer configured to determine a measured value RPM of the turbine; and a learn controller configured to control the oil pressure applier to apply the oil pressure to the non-operating friction element during a preset reference time and control the initial fill time based on the RPM peak to peak of the turbine showing a difference between the measured value RPM of the turbine determined by the RPM measurer and a preset targeted value, while a vehicle is in a coasting operation in an in gear state. |
