Abstract: When a synchronizing sleeve that is driven by an actuator in response to gear shift request is stroked from a release position to an engagement position, a differential rotation speed between an input rotation and an output rotation is calculated at stroke positions after a synchronization completion position; and when the said differential rotation speed is equal to or more than a predetermined threshold value, a damage determination index is calculated based on the said differential rotation speed. Further, when a cumulative value of the damage determination index accumulated for each gear position becomes equal to or more than a predetermined threshold value, the engagement operation of the gear position corresponding to the said cumulative value is disabled. This makes it possible to effectively determine the degree of damage when a gear whine occurs to a synchronized engaging device.
Abstract translation: 当由致动器响应于变速请求而驱动的同步套筒从释放位置被触发到接合位置时，在同步完成位置之后的行程位置处计算输入旋转和输出旋转之间的差速旋转速度; 并且当所述差速旋转速度等于或大于预定阈值时，基于所述差速旋转速度来计算损伤确定指数。 此外，当对于每个档位累积的伤害判定指标的累积值变为等于或大于预定阈值时，与所述累积值相对应的档位的接合操作被禁用。 这使得可以有效地确定当齿轮发生到同步接合装置时的损坏程度。

Abstract: A transmission includes first and second input shafts connected via a first clutch to a power source, an output shaft, a first shift gear group including shift gears arranged between the first input and output shafts, a first switching mechanism including a synchronizer for selecting one shift gear from the group, a second shift gear group including shift gears arranged between the second input shaft and the output shaft, and a second switching mechanism including a synchronizer for selecting one shift gear from the group. In order to learn a synchronizer balk position, either the first or second shift gear group, where no targeted synchronizer belongs, is set to any shift gear, both the first and second clutches are engaged, the balk position of the synchronizer is detected in a process of the targeted synchronizer being slid, and information specifying the detected position is stored.
