Line pressure control system for automatic transmission |
| abstract |
A hydraulic pressure control system for an automatic transmission comprising a multiple transmission gear mechanism having a plurality of gear stages and frictional elements for switching power transmitting paths in the transmission gear mechanism, hydraulic control mechanism for controlling engagement and disengagement of the frictional elements to establish one of said gear stages, line pressure control valve (32) for controlling line pressure of said hydraulic control mechanism (30), solenoid valve (33) for receiving a control signal and controlling a pilot pressure based on the control signal allowing the line pressure control valve (32) to control the line pressure, frequency control device (100) for increasing a frequency of the control signal for the solenoid valve (33) during a shift operation of the transmission. A responsive line pressure control is accomplished to reduce the torque shock during a shift operation of the transmission. |
