摘要：
The line oil pressure PL that is a basic pressure of a needed Pin pressure and a Pd pressure is set by line oil pressure setting device on the basis of the higher oil pressure of the oil pressure values obtained by adding reference margin values EX to the needed Pin pressure and the to Pd pressure. Therefore, a requirement minimum line oil pressure PL with respect to the needed Pin pressure needed for shifting and the Pd pressure needed for the belt clamping pressure is appropriately set so that good shifting performance and good belt clamping pressure are secured.
