Continuously variable transmission

A continuously variable transmission, comprising:

• a continuous gear-change unit to increase and decrease a speed of a rotational output of a driving source used for causing an automobile to travel, the continuous gear-change unit capable of continuously changing a gear ratio;
• a gearshift lever that is capable of selecting by a driver a first position from a neutral position and a second position from the neutral position through the first position in a manual mode in to an upshift direction or a downshift direction;
• a timer that measures a duration time during which the gearshift lever is at the second position;
• a first gear-change operating unit to which a first gear-change operation is input;
• a second gear-change operating unit to which a second gear-change operation is input, the second gear-change operation being performed at a same time as the first gear-change operation or subsequently to the first gear-change operation;
• and
• a gear-change controlling unit that calculates a gear ratio by adding a predetermined gear ratio of the manual mode to a gear ratio corresponding to the duration time during which the gearshift lever is at the second position when detecting that the gearshift lever is moved to the second position from the neutral position through the first position toward the upshift or downshift direction in case of selecting the manual mode,
• wherein, in the first gear-change operation, which is operated by moving the gearshift lever to the first position from the neutral position, the gear-change controlling unit performs gearshift from a present gear ratio to a next-predetermined gear ratio of the manual mode, and
• wherein, in the second gear-change operation, which is detected that the gearshift lever has moved from the neutral position to the second position through the first position, the gear-change controlling unit performs gearshift from the present gear ratio to an intermediate gear ratio that is added to the gear ratio corresponding to the duration time during which the gearshift is at the second position to a next predetermined gear ratio after the next predetermined gear ratio of the manual mode.
