CONTROL EQUIPMENT FOR AUTOMATIC TRANSMISSION

Japanese Patent JP3519030

B2

PROBLEM TO BE SOLVED: To provide a control equipment that conforms to a driver's sensibilities by measuring accurately a friction coefficient of clutch (friction coupling element), by deciding an appropriate volume of oil being supplied using the measured coefficient, and accordingly by absorbing effectively a shift shock.
SOLUTION: The control equipment computes an oil pressure value QATON to be applied (S1620) using those results such as FDISK (pushing pressure of hydraulic clutch) and other values that are derived, by calculating a revolution difference of dnm.nc (S1612) and a state value S (Sommerfeld equation value) (S1614), by retrieving a clutch disk coefficient of kinetic friction μd from the calculated state value S (S1616), and by calculating FDISK based on a targeted clutch torque TQON value (S1618).
