Line pressure control apparatus for continuously variable transmission

A line pressure control apparatus for a continuously variable transmission, which includes a primary pulley, a secondary pulley, and a V belt entraining the first and second pulleys, and in which line pressure is generated according to a running condition and oil pressure to be applied to the primary pulley and the secondary pulley is generated from the line pressure, the apparatus comprising:

• engine speed detecting means for detecting an engine speed;
• line pressure upper limit setting means for setting an upper limit of the line pressure;
• and
• line pressure control means for controlling the line pressure according to the running condition,
• wherein said line pressure upper limit setting means is operable when the engine speed detected by said engine speed detecting means is equal to or higher than a predetermined speed, for setting the upper limit of the line pressure, and
• wherein said line pressure control means controls the line pressure such that the line pressure does not exceed the upper limit of the line pressure set by said line pressure upper limit setting means regardless of the line pressure generated according to the running condition.
