  • Gear change control device
    Patent number: 9523426
    Abstract: A gear change control device is provided in which a feedback control level for making an actual gear ratio between input rotational speed and output rotational speed of a transmission coincide with a target gear ratio is calculated. A control level calculation device calculates the feedback control level based on a deviation of acceleration of change in the actual gear ratio with respect to acceleration of change in the target gear ratio thereby making it possible to enhance the control responsiveness compared with a case in which the feedback control level is calculated based on the deviation of the actual gear ratio with respect to the target gear ratio, and also to detect the occurrence of a deviation of the actual value from the target value at early stage and carry out feedback, thus enabling gear change control to be carried out more linearly than in a conventional manner.
