Technical Examples
  1. An automatic transmission control device adjusts a hydraulic pressure of a working fluid to generate pressures applied to a plurality of friction elements of an automatic transmission to control the engagement or disengagement of the friction elements. The control device includes a plurality of electromagnetic valves, a plurality of application pressure control valves, a selector, and a line pressure control valve. The application pressure control valves control pressures applied to the friction elements according to the output pressures of the electromagnetic valves. The selector selects the maximum pressure from the output pressures of the electromagnetic valves. The line pressure control valve controls a line pressure according to the output pressure selected by the selector.
