METHOD FOR USING SOFTWARE/ELECTRONIC COMPONENTS TO CORRECT AUTOMATIC TRANSMISSION CONTROL SYSTEM, ESPECIALLY MEASURING COEFFICIENTS OF SPECIFIC EQUATION ARE CHECKED

摘要

PURPOSE: A method for using software/electronic components to correct an automatic transmission control system is provided to correct a solenoid installed between valves and valve systems. CONSTITUTION: According to the method(70) for correcting an electronic hydraulic control system providing output response in response to an input current, a specific equation of an electronic hydraulic system including a number of coefficients is checked(72). The electronic hydraulic system is connected to a test stand. A number of currents are applied to the electronic hydraulic system. Output response of the electronic hydraulic system as to each of the currents is measured. And the coefficients of the specific equation are checked from output response measurement values(78).
