HYDRAULIC CONTROL SYSTEM OF AUTOMATIC TRANSMISSION FOR A VEHICLE

摘要

An automatic transmission controller which provides smooth shifting of gears and reduces gear shifting-caused shocks during a change in speed. There is provided a control means whereby, when gear shifting of the automatic transmission is decided during a switch-on of an air-conditioning unit, then the air-conditioning unit is kept on at least during the aforesaid gear shifting. Further, the control means selects an air conditioner-on-mode timer table in order to actuate the transmission in a controlled manner, and then to control a rev-up state of the engine speed.
