Line pressure control device and method for belt type continuously variable transmission |
摘要 |
In a line pressure control device for a belt type continuously variable transmission according to this invention, when a line pressure is feedback-controlled to equal a target line pressure which is equal to or greater than the larger of oil pressures supplied to a primary pulley and a secondary pulley (S1), and it is determined that the target line pressure has fallen below a first low pressure, leading to a divergence between the target line pressure and the actual line pressure (S6), the target line pressure is restricted such that the target line pressure does not fall below a lower limit value (S7). |
