Hybrid vehicle and method of controlling transmission

A hybrid vehicle comprising:

• a driving information detection unit configured to interoperate with various sensors of the hybrid vehicle to detect driving information according to operation of the vehicle;
• a driver acceleration/deceleration prediction unit configured to generate a predicted value of a near-future acceleration/deceleration intention of a driver reflecting a driving environment of the vehicle, using information transmitted from the driving information detection unit by utilizing an acceleration/deceleration prediction model;
• a hybrid control unit configured to determine a first torque and determine a second torque using the predicted value of the near-future acceleration/deceleration intention, the first torque being a current required torque and the second torque being a required torque expected to be generated at a near-future time after a current time;
• and
• a transmission control unit configured to compare, when the first torque is greater than or equal to a first threshold, the second torque with a second threshold set according to the near-future time and to control a transmission to perform downshifting when the second torque is greater than or equal to the second threshold as a result of the comparison.

• wherein the hybrid control unit controls the transmission control unit to maintain a current transmission gear stage when the first torque is less than the first threshold value or when the second torque is less than a second threshold value set according to the near-future time as a result of comparison between the second torque and the second threshold value.
