Patent AT-E401516-T1: [Translated] AUTOMATIC SHIFT CONTROL DEVICE FOR A MOTOR VEHICLE AND METHOD FOR DETERMINING THE SYNCHRONOUS POINT

A vehicle automatic shift operation controlling apparatus includes a synchronizer ring (32) having plural synchronizer ring teeth (320) arranged circumferentially at the synchronizer ring (32), and an opposing member (47) having plural opposing teeth (470) circumferentially at the opposing member (47), the plural opposing teeth (470) engageable with the plural synchronizer ring teeth (320) at a time of a change in a gear ratio in a transmission (2). The apparatus further includes a first processing unit (6m) configured to determine in actual practice a first balk point, which is one of the shift-up and shift-down side balk points, by implementing one of the shift-up and shift-down operations; and a second processing unit (6n) configured to anticipate, on a basis of the first balk point, a predicted value of a second balk point which is an other one of the shift-up and shift-down side balk points. <IMAGE>
