Patent number: 6454675Abstract: A line pressure control device for a continuously variable transmission comprises: a target line pressure setting part that sets a target value of a line pressure, which is able to adjust a clamping force applied to a transmission member of the continuously variable transmission; and an engine torque suppressing part that suppresses an engine torque to prevent the transmission member from slipping. When it is impossible to suppress the engine torque and thus a torque non-suppressible flag is set, the target value of the line pressure is corrected to a greater value to prevent the transmission member from slipping. Otherwise, the target value of the line pressure is set to a smaller value. This makes it possible to surely prevent the transmission member from slipping.Type: GrantFiled: April 26, 2001Date of Patent: September 24, 2002Assignee: Mitsubishi Jidosha Kogyo Kabushiki KaishaInventors: Hiroki Asayama, Tatsuo Nakamura
