RUN-UP LEARNING METHOD IN THE POWER ON UP SHIFT TRANSMISSION OF THE VEHICLE WHICH THE FLUID PRESSURE OF THE RELEASE ELEMENT IS OPTIMIZED, CAN RISE THE SPEED CHANGE QUALITY AND DURABILITY

摘要

PURPOSE: The correction time of the fluid pressure duty factor of the release element is reduced by revising the fluid pressure duty factor of the release element to the correction fluid pressure having the run-up learning method in the power on up shift transmission of vehicle is the correction slope and goal status and correction time.;CONSTITUTION: The turbine rotational number variation rate is detected among the power-on up shift gear shift process in the shift begin point(101). Run-up is created the turbine rotational number variation rate to the basis(107). It is outputted from the map table value corresponding to the run-up size in which the correction fluid pressure pitches the turbine rotational number variation rate as the basis(111). It is driven to the fluid pressure duty factor having the release element is the goal status(113).;COPYRIGHT KIPO 2010
