摘要： A continuously variable transmission (100), wherein pressure equalization control is performed to make line pressure (PL) equal to secondary pressure (Psec) when prescribed start conditions are satisfied. During pressure equalization control, a secondary pressure indicated value (Psec_co) is raised by a prescribed amount (S10), then a line pressure indicated value (PL_co) is gradually decreased (S30). If determination is made that line pressure is the same as the secondary pressure after secondary actual pressure (Psec) is lowered (S40), then the line pressure is controlled so that the secondary actual pressure (Psec) becomes the secondary pressure indicated value (Psec_co) (S50). At the start of pressure equalization control, if the difference (ΔPsec) found by subtracting the secondary pressure indicated value from the secondary actual value is negative (S120), then a primary pressure indicated value is corrected on the basis of the difference (S130).
摘要翻译：一种无级变速器（100），其中，当满足规定的起动条件时，执行均压控制以使管线压力（PL）等于二次压力（Psec）。在压力平衡控制期间，次级压力指示值（Psec_co）升高规定量（S10），然后管路压力指示值（PL_co）逐渐减小（S30）。如果在二次实际压力（Psec）降低之后确定管路压力与次级压力相同（S40），则管路压力被控制为使得次级实际压力（Psec）变为次级压力指示值（Psec_co ）（S50）。在压力均衡控制开始时，如果通过从次级实际值减去次级压力指示值求得的差值（ΔPsec）为负值（S120），则基于该差值校正主压力指示值（S130）。
