<P>PROBLEM TO BE SOLVED: To take measures by correctly detecting vibration of a belt in a vehicle on which a belt-type continuously variable transmission is mounted. <P>SOLUTION: An ECT_ECU executes a program including a step (S100) of detecting the clamping force of the belt, a step (S110) of analyzing variation in the clamping force (vibration data) of the belt, and a step (S150) of controlling the clamping force for avoiding the belt vibration when judging that the vibration occurs in the belt (YES in S140) in the case where a frequency f of the vibration data is within a predetermined range (YES in S120) and in the case where a state in which an amplitude A of the vibration data is equal to or larger than a threshold value continues for a period of time equal to or larger than a predetermined time (YES in S130). <P>COPYRIGHT: (C)2007,JPO&INPIT |
